    Full Text Available GRADSTEIN, R.    et al. 2010. Bryophytes of Mount Patuha, West  JavaIndonesia.  Reinwardtia  13(2:  107–123. This  paper  presents  the  results  of  a  two–day  survey  of  the  bryophyte  flora of Mt.  Patuha  and  its  surroundings  near Bandung, West Java, carried out in the framework of the 5th regional training course on bryophyte and lichen diversity and conservation organized by SEAMEO BIOTROP, Bogor, in July 2009. A total of 159 bryophyte species were identi-fied,  including 98 mosses, 60  liverworts, and 1 hornwort, representing almost 1/6 of the  total bryophyte flora of Java. Three moss species, Bryohumbertia subcomosa (Dix. J.–P. Frahm, Fissidens gymnogynus Besch. and F. polypodioidesHedw., and one liverwort, Lejeunea pectinella Mizut., are new additions to the Javanese flora. The bryophyte diversity of Mt. Patuha is well representative of the Malesian flora and is rich in uncommon species. However, the relatively poor representation of shade epiphytes and commonness of sun epiphytes and generalists reflect disturbance of the forest by anthropogenic activities. Careful attention should be given  to conservation of  the  remaining natural  forest  in order  to prevent further losses of the rich bryophyte diversity of the area.

    The climatology and variability of dry spells are valuable information for scientists, engineers, planners, and managers working in water-related sectors such as agriculture, ecology, hydrology, and water resources. The dry spell concerns consecutive dry days which are the largest number of consecutive days with less than 1 mm of daily precipitation within a year. The objective of this study is to analyse the spatial and temporal characteristics of dry spells and also specifically investigate the frequency patterns of the dry spell distribution based on historical observed daily precipitation from 1981 to 2010. The longest dry spell occured at Pasirukem with the length of 252 days. The northern coast of West Java have higher probabilities of dry spells more than 5, 10, 15, and 20 days.

    Java Island, Indonesia is the most populated area and one of the most tectonically active coastal nations on Earth. This island is the volcanic arc and accretionary wedge of the subduction zone of the Sunda and the Australia plate, where the Java Trench is located. However, the Java Trench hasn't had a mega or giant earthquake for at least 430 years according to historical records. Up to 30 m of slip may have accumulated on the subduction zone interface during this time, which is enough to produce a Mw 9.0 earthquake and large tsunami. One of the largest seismic gaps along the Sunda Arc is a 640 km section of the coast of west Java. The largest population center in this region is Pelabuhan Ratu, with is partially built on ridge and swale coastal plain topography. Candidate tsunami deposits were found in swales that may indicate inundation up to 1 km inland. Numerical modeling of various possible tsunami scenarios indicate that the configuration of the coastline may amplify a tsunami and cause high run-up in the most populated areas or the coast. Also, data from questionnaire surveys administered in Pelabuhan Ratu show a lack of awareness about how tsunamis threaten these communities and plans of action.

    Dengue is endemic and affects people in all Indonesian provinces. Increasing dengue cases have been observed every year in Sukabumi in West Java province. Despite the endemicity, limited data is available on the genetic of dengue viruses (DENV) circulating in the country. To understand the dynamics of dengue disease, we performed molecular and serological surveillance of dengue in Sukabumi. A total of 113 patients were recruited for this study. Serological data were obtained using anti-dengue IgM and IgG tests plus dengue NS1 antigen detection. Dengue detection and serotyping were performed using real-time RT-PCR. Viruses were isolated and the envelope genes were sequenced. Phylogenetic and evolutionary analyses were performed to determine the genotype of the viruses and their evolutionary rates. Real-time RT-PCR detected DENV in 25 (22%) of 113 samples. Serotyping revealed the predominance of DENV-2 (16 isolates, 64%), followed by DENV-1 (5 isolates, 20%), and DENV-4 (4 isolates, 16%). No DENV-3 was detected in the samples. Co-circulation of genotype I and IV of DENV-1 was observed. The DENV-2 isolates all belonged to the Cosmopolitan genotype, while DENV-4 isolates were grouped into genotype II. Overall, their evolutionary rates were similar to DENV from other countries. We revealed the distribution of DENV serotypes and genotypes in Sukabumi. Compared to data obtained from other cities in Indonesia, we observed the differing predominance of DENV serotypes but similar genotype distribution, where the infecting viruses were closely related with Indonesian endemic viruses isolated previously.

    A tsunami earthquake (Mw = 7.7) occurred south of Java on 17 July 2006. The event produced relatively low levels of high-frequency radiation, and local felt reports indicated only weak shaking in Java. There was no ground motion damage from the earthquake, but there was extensive damage and loss of life from the tsunami along 250 km of the southern coasts of West Java and Central Java. An inspection of the area a few days after the earthquake showed extensive damage to wooden and unreinforced masonry buildings that were located within several hundred meters of the coast. Since there was no tsunami warning system in place, efforts to escape the large waves depended on how people reacted to the earthquake shaking, which was only weakly felt in the coastal areas. This experience emphasizes the need for adequate tsunami warning systems for the Indian Ocean region.

    Hart, Barry T; van Dok, Wendy; Djuangsih, Nani

    2002-04-01

    A preliminary nutrient budget for Saguling Reservoir is reported as a first attempt to quantify the behaviour of nutrients entering this reservoir. This work is part of a larger Indonesia-Australia collaborative research and training project, involving Padjadjaran University and Monash University, established to study nutrient dynamics in Saguling Reservoir. Saguling Reservoir, the first of a chain of three large reservoirs (Saguling, Cirata and Jatilahur), built on the Citarum River in central Java, was completed in 1985. It has already become highly polluted, particularly with domestic and industrial effluent (organic matter, nutrients, heavy metals) from the urban areas of Bandung (population 2 million). The reservoir experiences major water quality problems, including excessive growths of floating plants, toxic cyanobacterial blooms and regular fish-kills. The work reported in this paper shows that Saguling receives a very large nutrient load from the city of Bandung and because of this, is highly eutrophic. It is unlikely that the water quality of Saguling will improve until a substantial part of Bandung is sewered and adequate discharge controls are placed on the many industries in the region upstream of the reservoir.

    Full Text Available Thermal waters at Ciarinem and Cilayu, Pameungpeuk, West Java, Indonesia have different characteristics: Ciarinem water is a steam heated sulfate type and occurs as hot springs, whereas Cilayu water discharges as hot pools and is a chloride water type. Their chemical compositions indicate that the thermal waters are outflows of a volcanic–magmatic associated geothermal system. The solute geothermometers calculate that the subsurface reservoir temperatures range from 150o to 200ºC.

    This research was conducted to differentiate and characterize eight Newcastle disease virus (NDV) isolates collected from vaccinated chicken at commercial flocks in West Java, Indonesia, in 2011, 2014 and 2015 by pathotype specific primers. A total of eight NDV isolates collected from clinical outbreaks among commercial vaccinated flocks in West Java, Indonesia, in 2011, 2014, and 2015 were used in this study. Reverse transcription-polymerase chain reaction was used to detect and differentiate virulence of NDV strains, using three sets of primers targeting their M and F gene. First primers were universal primers to detect NDV targeting matrix (M) gene. Other two sets of primers were specific for the fusion (F) gene cleavage site sequence of virulent and avirulent NDV strains. Our results showed that three isolates belong to NDV virulent strains, and other five isolates belong to NDV avirulent strains. The nucleotide sequence of the F protein cleavage site showed (112)K/R-R-Q/R-K-R/G-F(117) on NDV virulent strains and (112)G-K/R-Q-G-R-L(117) on NDV avirulent strain. Result from the current study suggested that NDV virulent strain were circulating among vaccinated chickens in West Java, Indonesia; this might possess a risk of causing ND outbreaks and causing economic losses within the poultry industry.

    We isolated an arbovirus from bovine blood in Indonesia. The arbovirus was obtained from the plasma of a cow showing no clinical symptoms in West Java in February 2014, and was identified as Akabane virus (AKAV) by AKAV-specific RT-PCR and subsequent sequence analysis. Phylogenetic analysis based on partial S segment indicated the AKAV isolate, WJ-1SA/P/2014, was most closely related with two isolates from Israel and Turkey reported in 2001 and 2015, respectively, and that WJ-1SA/P/2014 isolate belongs to AKAV genogroup Ib. This is the first isolation of AKAV from Indonesia.

    Malaria is a serious health issue in Indonesia. We investigated the dusk to dawn anopheline mosquito activity patterns, host-seeking and resting locations in coastal plain, hilly and highland areas in West Timor and Java. Adult mosquitoes were captured landing on humans or resting in houses or animal barns. Data analyzed were: mosquito night-time activities; period of peak activity; night-time activity in specific periods of time and for mosquito resting locations. Eleven species were recorded; data were sparse for some species therefore detailed analyses were performed for four species only. In Java Anopheles vagus was common, with a bimodal pattern of high activity. In West Timor, its activity peaked around midnight. Other species with peak activity around the middle of the night were An. barbirostris and An. subpictus. Most species showed no biting and resting preference for indoors or outdoors, although An. barbirostris preferred indoors in West Timor, but outdoors in Java. An. aconitus and An. annularis preferred resting in human dwellings; An. subpictus and An. vagus preferred resting in animal barns. An. barbirostris preferred resting in human dwellings in West Timor and in animal barns in Java. The information is useful for planning the mosquito control aspect of malaria management. For example, where mosquito species have peak activity at night indoors, bednets and indoor residual spraying should reduce malaria risk, but where mosquitoes are most active outdoors, other options may be more effective.

    2013-01-01

    Full Text Available Motorcycle provides several positive aspects in providing mobility, but its rapid increase in ownership and usage should be anticipated. The West Java Province has the highest number of population in Indonesia, which is potential to have the highest number of motorcycle. This study aims to develop a prediction model of motorcycle number and to develop a model of motorcycle ownership. Two models are proposed to predict the motorcycle growth in West Java, with gross regional domestic product and number of population as the independent variables. Four ordered probit models are proposed to explain motorcycle ownership in Bandung City based on economic, personal, user’s travel behavior, and motorcycle characteristics. This study explains that the increase of motorcycle ownership was not influenced by economic condition only, but also by travel behavior and their activity. Thus, besides economic aspects, the anticipation should also be based on travel and activity changes of the user.

    Full Text Available A study at several geothermal systems in West Java, Indonesia shows that thermal waters could naturally contain up to 2.6 ppm As and 6.5 ppb Hg, and the surface hydrothermal alteration could contribute up to 50 ppm As and 800 ppb Hg. The higher the chloride content, the higher the contents of As and Hg of thermal waters. The amounts of As and Hg in an active geothermal system are influenced by the type of host rock, boiling and mixing processes, and adsorption of vapor and volcanic gases into thermal waters.

    Malaria is a serious health issue in Indonesia. Mosquito control is one aspect of an integrated malaria management programme. To focus resources on priority areas, information is needed about the vectors and their habitats. This research aimed to identify the relationship between anopheline mosquitoes and topography in West Timor and Java. Study areas were selected in three topographic types in West Timor and Java. These were: coastal plain, hilly (rice field) and highland. Adult mosquitoes were captured landing on humans identified to species level and counted. Eleven species were recorded, four of which were significant for malaria transmission: Anopheles aconitus, Anopheles barbirostris, Anopheles subpictus and Anopheles sundaicus. Each species occupied different topographies, but only five were significantly associated: Anopheles annularis, Anopheles vagus and Anopheles subpictus (Java only) with hilly rice fields; Anopheles barbirostris, Anopheles maculatus and Anopheles subpictus (West Timor only) with coastal areas. Information on significant malaria vectors associated with specific topography is useful for planning the mosquito control aspect of malaria management.

    We have conducted seismic tomographic inversions to obtain a P-wave seismic velocity structure beneath the Sunda Strait and West Java regions, Indonesia. The Sunda Strait is located in a complex geological system i.e. in the transition from the oblique subduction beneath Sumatra to the nearly perpendicular subduction below Java. The Krakatau active volcano is located in the Sunda Strait. In this study, we have used selected P-wave arrival times from the data catalogs of the SeisComP-BMKG network (from 2009 to 2011) and the BMKG BALAI II network (from 1992 to 2011) compiled by Badan Meteorologi,Klimatologi dan Geofisika (BMKG), Indonesia. In total, there are 1,598 local earthquakes and 10,366 P-wave phases from 25 seismographic stations that have been used for the tomographic inversions. We have also relocated the hypocenter locations along with velocity inversions simultaneously. Our preliminary results depict some prominent geological features that include: (1) a low velocity anomaly beneath north of the Ujung Kulon region, which coincides with a low gravity anomaly resulting from a previous study, (2) a low velocity anomaly alignment beneath the Krakatau volcano in the Sunda Strait, (3) a sharp contrast in velocity anomalies extending from Pelabuhan Ratu towards Jakarta with a strike of SW-NE, and (4) a low velocity anomaly in the offshore of Pelabuhan Ratu that may be correlated with the continuation of the Cimandiri fault zone. More detailed information will be presented during the meeting. Keywords: tomography, Sunda Strait, West Java, velocity anomaly

    Full Text Available Some hypertensive subjects in Indonesia consume traditional herbal medicines in addition to the usual pharmacological drugs. This paper studied the relationship between several traditional herbal medicines, such as morinda, star fruit, garlic, or jamu, believed to control hypertension and the risk of current pharmacological antihypertensive drug users in subjects with stage 1 and 2 hypertension in a rural community West Java, Indonesia. The data were obtained from 3 field studies by the second year medical students of the Faculty of Medicine, University of Indonesia conducted in 2001, 2002, and 2003 in a subdistrict of the Bogor regency. The subjects were selected randomly from neighborhood clusters. Interviews and blood pressure measurements were conducted at the houses of the subjects by specially trained second year medical students supervised by faculty members. There were 496 subjects with stage 1 or 2 hypertension, with 11.5% under current antihypertensive drugs. Compared with the hypertension stage 1 subjects, hypertension stage 2 subjects were 5.4 times more likely to be currently taking pharmacological antihypertensive medication (adjusted odds ratio = 5.44; 95% confidence interval = 2.64-11.27. The combined of current antihypertensive medication with traditional medicines were cucumber which being the most dominant followed by star fruit and morinda. Reasons for this were probably the strong influence of culture, the limited medical facilities, and high cost of the antihypertensive drugs. It was concluded that in a rural Indonesia, it was common for hypertensive subjects to take pharmacological drugs as well as traditional medicine for antihypertensive therapy.

    Cianjur Regency is one of “lumbung” paddies in West Java Province that can contribute to rice sufficiency for West Java 13.5%. However conversion of paddy field into other land use still happen in Indonesia because of land rent of paddy field less than other land use and also the low commitment of Government to protect the paddy field to get food self-sufficiency. Objectives are analysis of paddy field protection and recommendation of regional planning. Paddy field protection was determined based on existing paddy field, land suitability, economic value and Regional Spatial Planning (RTRW). Recommendation of regional planning was determined based on priority level of paddy field protection, Regional Spatial Planning (RTRW) and rice sufficiency status. The results showed that land suitability, economic value and also allocating land for paddy field in the RTRW can support realization of paddy field protection. The paddy field that included into the first and third priority is 30.14% and 38.45%, respectively. The other priorities of paddy field protection are around 15%. This research is recommended that 87.5% of the paddy field existing can be protected to get rice sufficiency with surplus around 48.782 ton.

    West Java is one of the provinces in Indonesia which is prone to landslide. Over the past few years, landslides in this area have resulted in a large number of victims. One of the areas in West Java with the highest risk of landslide occurrence is Rancabali Ciwidey. In general, the morphology around the landslide location is steep hills, with the slope > 30° and the altitude between 1550 - 1865 m above sea level. Several indications of ground movements can be seen in the form of slumps and cracks on the village roads and tea plantation, as well as slanting trees and electricity poles. The ground movement monitoring in this area is necessary for disaster mitigation. Several methods that can be used to monitor the landslide are using Terrestrial Laser Scanner (TLS) and robotic total station. This research aims is monitoring the landslide using these methods. The methodology used in this research is by obtaining the scanning data using TLS C-10 and Robotic total station MS05 measurements to obtain the coordinates of monitoring point clouds and prism. The TLS software that we used are Cyclone 8.1 and Maptek I-Site. For robotic total station, the software that we used is MSP software. These method hopefully can be used for early warning system of landslide in Rancabali area.

Community structure and habitat associations of amphibians and reptiles on both rainy and dry seasons of six habitat types of three sites in Gunung Ciremai National Park, West Java were investigated in March and October 2008. The data of herpetofauna was obtained by opportunistic searches. Herpetofaunal diversity for each habitat was determined by using Shannon Wiener index, the species abundance per unit area was calculated by using Margalef’s index, and the homogeneity of distribution of species in relation to other species in a sampled per unit area was evaluated using Evenness index. The similarity in herpetofauna communities among habitat types was determined using Sorensen’s coefficient, meanwhile the Jaccard’s index was used to estimate similarities in habitat utilization. Thus, both of community similarities and habitat utilization displayed in cluster dendrogram. A total of 46 amphibian and reptile taxa were recorded, comprising 16 anurans, 22 lizards and 8 snakes. Of the total taxa, four anurans are endemic and an unusual specimens probably new in sciences referred to the genus Cyrtodactylus and Eutropis. There were differed in sequential of biological indices among habitat types but not much different in their values. The result of cluster analysis showed different patterns on the community similarity among habitat type and habitat utilization during rainy and dry seasons.

    To determine the water environment and pollutants in West Java, the contents of metals and general water quality of the Ciliwung River in the Jakarta area were measured. High Escherichia coli number (116-149/mL) was detected downstream in the Ciliwung River. In addition to evaluate mercury pollution caused by gold mining, mercury contents of water and sediment samples from the Cikaniki River, and from paddy samples were determined. The water was not badly polluted. However, toxic metals such as mercury were detected at levels close to the baseline environmental standard of Indonesia (0.83-1.07 μg/g of sediments in the Cikaniki River). From analyses of the paddy samples (0.08 μg/g), it is considered that there is a health risk caused by mercury.

    Large-scale landslide occurred in Margamukti village, Pangalengan, Bandung Regency, West Java Province, Indonesia. The landslide damaged geothermal gas pipeline along 300 m in Wayang Windu Geothermal Field. Based on field observation, landslide occured in rotational sliding movement. Laboratory analysis were conducted to obtain the characteristics of the soil. Based on the condition of the landslide in this area, the Factor of Safety can be simulated by the soil mechanics approach. Factor of safety analysis based on soil cohesion and internal friction angle was conducted using manual sensitivity analysis for back analysis. The analysis resulted soil cohesion in critical condition (FS<1) is 6.01 kPa. This value is smaller than cohesion of undisturbed slope soil sample. Water from rainfall is the most important instability factors in research area. Because it decreases cohesion in soils and increases weight and pore water pressure in granular media.

    2010-03-01

    Full Text Available Organic farming provides many benefits in Indonesia: it can improve soil quality, food quality and soil carbon sequestration. This study was designed to compare soil carbon sequestration levels between conventional and organic rice farming fields in west Java, Indonesia. The results from soil analysis indicate that organic farming leads to soil with significantly higher soil carbon storage capacity than conventional farming. Organic farming can also cut some farming costs, but it requires about twice as much labor. The sharecropping system of rice farming in Indonesia is highly exploitative of workers; therefore, research should be conducted to develop a fairer organic farming system that can enhance both local and global sustainability.

    Full Text Available Sundanese are the largest indigenous ethnic group in the western part of Java Island. Sundanese culture closely relates to Animist, Hindu-Buddhist, and Islam philosophies. It led to the unique creation of the Sundanese traditional houses called Rumah Adat in Kampung Naga where the ancient tradition from their ancestor were upheld until today. Kampung Naga was listed as one of the Sundanese traditional villages known as Kampung Adat in West Java. This village has its own characteristics which enable the conveyance of tremendous tradition from the past, since the reign of Padjajaran Kingdom to the present. Additionally, it has the ability to accelerate globalization of culture these days. The objectives of this paper are to reintroduce and observe the in-depth meaning of Sundanese traditional houses within Kampung Naga. This paper employed qualitative investigation with the support of exploratory literature review. The result of this study portrayed that Sundanese traditional village are depicted as sacred spaces when the founder, the belief, and the nature spirit are interrelated. Thus, the creation of traditional houses in Kampung Naga does not only serve as shelters, but it also has “breath”, “soul” and may embody cosmological value. This paper is prominent in the documentation of Sundanese traditional buildings as one of cultural identity of Indonesia, which will deliver the cultural knowledge to the world wide.

    Demographic and Health Survey Indonesia (DHSI) is a national designed survey to provide information regarding birth rate, mortality rate, family planning and health. DHSI was conducted by BPS in cooperation with National Population and Family Planning Institution (BKKBN), Indonesia Ministry of Health (KEMENKES) and USAID. Based on the publication of DHSI 2012, the infant mortality rate for a period of five years before survey conducted is 32 for 1000 birth lives. In this paper, Small Area Estimation (SAE) is used to estimate the number of infant mortality in districts of West Java. SAE is a special model of Generalized Linear Mixed Models (GLMM). In this case, the incidence of infant mortality is a Poisson distribution which has equdispersion assumption. The methods to handle overdispersion are binomial negative and quasi-likelihood model. Based on the results of analysis, quasi-likelihood model is the best model to overcome overdispersion problem. The basic model of the small area estimation used basic area level model. Mean square error (MSE) which based on resampling method is used to measure the accuracy of small area estimates.

    We have deployed about 48 three component seismometers around "AFA" hydrothermal are in West Java, Indonesia from October 2012 up to October 2014 in order to detect microseismic event and to enhance our knowledge about subsurface seismic stucture. The seismometer network in this study, is the first dense seismometer array monitoring around hydrothermal area in Indonesia so far. We analyzed a huge waveform data set to distinguish microseismic, local and regional events. Then, we picked the onset of P-and S-wave arrival of microseismic events carefully visually by eye. We determined the initial microseismic event by applying Geiger's method with uniform seismic velocity model. Totally, we have been successfully determined 2,497 microseismic events around this hydrothermal area. We also improved 1D seismic velocities (Vp, Vs) and simultaneously with hypocenter adjustment as input for the tomography inversion in this study. Overall, the microseismic events are concentrated around production area activities and we also found strong cluster microseismic event in Southern part of this region which still need to be investigated in more details. Now, we are going on tomographic inversion step by using double-difference method. We are going to show more information during the meeting.

    Administering a half dose of an anthelmintic is a simple method for detecting resistance in parasites infesting small ruminants. When a single anthelmintic fails in native sheep from Indonesia, a combination of anthelmintics from different chemical classes with different modes of action are administered as an alternative parasite-control strategy. This study compared the anthelmintic efficacy of ivermectin (IVM) and albendazole (ABZ) given either separately as a single dose or half dose or co-administered to sheep naturally infected with Haemonchus contortus. Twelve sheep from Bogor, West Java, Indonesia were divided into the following six treatment groups: half-dose IVM, full-dose IVM, half-dose ABZ, full-dose ABZ, combined IVM + ABZ, and control. The treatment efficacy was determined using the faecal egg count reduction test (FECRT) at day 0 (pre-treatment) and post-treatment at days 7, 14, 21, 28, 35, and 42. The efficacies of half-dose IVM, full-dose IVM, half-dose ABZ, full-dose ABZ, and the combination treatment ranged from -1900% to 100%, 99% to 100%, -167% to 100%, -467% to 89%, and -200% to 100%, respectively. The FECRT for the half-dose IVM, half-dose ABZ, full-dose ABZ showed that H. contortus is resistant to half-dose IVM and ABZ. Full-dose IVM was effective against H. contortus. The combined treatment was more effective against H. contortus than ABZ alone.

    Spatially, climate condition is vary within a region and considered as essential information for planning activities such as agro-climate zonation. An approach to understand the spatial climate variability is the utilization of climate regionalization that is applied to rainfall data to distinguish differences in the pattern and magnitude (characteristics) of spatial rainfall variability over a region. Unfortunately, the application of climate regionalization poses a challenging issue in Indonesia, considering the availability of climate data. Recent advances in satellite and reanalysis data measuring climate variability over a large area provided an opportunity for the application of climate regionalization in the country. Using the West Java, one of main crop production regions in Indonesia, climate regionalization techniques were applied to map spatial variability of climate types based on rainfall data recorded by climate stations (point based analysis) and estimated by modeled/reanalysis data and satellite observations (gridded data). The regionalization derived from gridded rainfall data have reasonably better in capturing the zonal pattern of differences in climate types within the study region than the regionalization applied to insufficient numbers of site-based rainfall observation. This indicates that the gridded data offers an alternative for climate regionalization, when site-based observations are unavailable or limited.

    Background The village midwife is a central element of Indonesia's strategy to improve maternal and child health and family planning services. Recently there has been concern that the midwives were not present in the villages to which they had been assigned. To determine the extent to which this was the case we conducted a field-based census and survey of village midwives in three districts in West Java Province, Indonesia. Findings In June 2009 we interviewed a random sample of village midwives from three districts - Ciamis, Garut and Sukabumi - in West Java Province. Trained interviewers visited all villages represented in the sample to interview the midwives. We also obtained information about the midwives and their professional activities in the last year. Thirty percent of village midwives had moved to another location in the 12 months between the end of 2008, when the sampling frame was constructed, and December 2009 when the survey was conducted; most had moved to a government health center or another village. Of those who were present, there was considerable variation between districts in age distribution and qualifications. The total number of services provided was modest, also with considerable variation between districts. The median number of deliveries assisted in the last year was 64; the amount and mix of family planning services provided varied between districts and were dominated by temporary methods. Conclusions Compared to an earlier survey in an adjacent province, the village midwives in these three districts were younger, had spent less time in the village and a higher proportion were permanent civil servants. A high proportion had moved in the previous year with most moving to a health center or another village. The decision to move, as well as the mix of services offered, seems to be largely driven by opportunities to increase their private practice income. These opportunities are greater in urban areas.

    Full Text Available Talun-huma is an intensified land use system for swidden agriculture in Indonesia. Talun is a productive fallow system that is meaningful from ecological, social, and economic perspectives. Although it is considered a typical practice in West Java, this study proves that the term talun was used in many places in Indonesia besides West Java during colonial times.  This study also shows that talun-huma and agroforestry practice in the surveyed village is closely linked to the socioeconomic structure of the rural society based on the data collected in 2000–1. Huma is more likely to be practiced by the lower strata owning little agricultural and forestry land. The economic development reflected in the growth of banana leaf production and income from the non-­agricultural sector income has not excluded or diminished talun-huma and agro­forestry practices. Sharecropping practices and agricultural labor relations among the villagers have established huma practice. The social forestry program implemented in this region also supports the continuity of huma practice. Increase in banana leaf production does not diminish the practice of huma and talun agro­forestry, although banana leaf production tends to shorten the duration of the cycle. Moreover, the development of non-agricultural sectors and wet rice cultivation has had a positive impact on the existence of huma practices and the continuation of slash-and-burn practices.  Talun-huma and permanent forests with or without talun are good practices that keep the system sustainable from an economic and social point of view. Diversified farming, balanced rotation of land use, and diversity of plants, as well as the planting of leguminous land conservation trees such as kaliandra and gamal, play an important role in sustaining the system.  The introduction of banana leaf plants to the village in the 1990s has contributed significantly to the continuity of the system because the plants are a

    The assessment of geothermal resources requires the understanding of the structure and the dynamics of geothermal reservoirs. We deployed a multidisciplinary geophysical network around geothermal areas in the south of Bandung, West Java, Indonesia. The first deployment included a network of 30 broadband and 4 short-period seismic stations with Güralp and Trillium sensors (0.008 - 100 Hz) since October 2012. In a second step, we extended the network in June 2013 with 16 short-period (1 Hz) seismometers. We describe the set-up of the seismic networks and discuss first observations and results. The co-existence of a large variety of intense surface manifestations like geysers, hot-steaming grounds, hot water pools, and active volcanoes suggest an intimate coupling between volcanic, tectonic and hydrothermal processes in this area. Preliminary location of earthquakes is performed using a non-linear algorithm, which allows us to define at least 3 seismic clusters. We discuss this seismic pattern within the geothermal fields.

    In Indonesia, because of the rapidly growing demand for dairy products, the development of milk production in rural communities can play a strong role in reducing poverty. However, the development of smallholder dairy production requires adequate support from the government, development organizations, and private firms. To assess the needs and situations of poor dairy farmers, we conducted a study in Ciater sub-district in West Java Province to compare the current situation with the situation that prevailed 4 years ago, i.e., before the implementation of a dairy development project. Data were collected from 61 farms in June 2014. The average number of cows on the farms surveyed was three to four, and each relied on cultivating an average of 0.4 ha of forage. Results showed that thanks to the project activities, milk productivity per cow and net income from milk production increased by 25% between 2010 and 2014. These results underline the importance of providing training and technical support for the development of the livelihoods of dairy smallholders.

We describe the set-up of the seismic and geodetic networks and we discuss first observations and results. As a first estimation of this excellent data set, we performed preliminary location of earthquakes using a non-linear algorithm, which allows us to define at least 3 seismic clusters. We use this first estimate to perform joint inversion tomography of hypocenters and velocity model. We discuss the found seismic pattern within the area.

    A 15-month bionomic study of Anopheles species was conducted in two ecologically distinct villages (coastal and upland) of Sukabumi District, West Java, Indonesia from June 2006 to September 2007. Mosquitoes were captured using human-landing collections at both sites. During the study, a total of 17,100 Anopheles mosquitoes comprising 13 Anopheles species were caught: 9,151 at the coastal site and 7,949 at the upland site. Anopheles barbirostris, Anopheles maculatus, and Anopheles vagus were the predominant species caught at the coastal site, and Anopheles aconitus, Anopheles barbirostris, and An. maculatus predominated in the upland site. Overall, species were exophagic at both sites, but there was variation between species. Anopheles aconitus was endophagic at the coastal site, exophagic at the upland site, collected most often in April 2007 and had a peak landing time between 22:00 and 23:00. Anopheles sundaicus was only collected at the coastal site, exophagic, collected most often in October 2006, and had a peak landing time between 19:00 and 20:00. Potential malaria vector species such An. aconitus, An. maculatus, and An. sundaicus were present throughout the year. None of the 7,770 Anopheles tested using CSP-ELISA were positive for malaria, although the risk for malaria outbreaks in Sukabumi district remains high.

    Dietary habits of children, including snack foods consumption, in developing countries have seldom been investigated in relation to their nutrition and health. To assess the effects of snack foods consumption of 154 children aged 1-12 years in a rural village of West Java, Indonesia, a 3-hour-interval food recall survey for all meals and snack foods consumed in seven consecutive days for each subject, anthropometry, and interviews for sociodemographic indicators were conducted. Their overall prevalence of stunting and underweight was 69.5% and 35.7%. There were 221 foods consumed by the subjects, among which 68 foods were categorized as snack foods. Though the children of both <7 year and ≥7 year age groups consumed snack foods similarly throughout the day, the latter group only consumed larger amounts of energy from snack foods at school recess-times. The mean percent contribution of snack foods was 59.6% for fat, 40.0% for energy, 20.6% for calcium, and <10% for vitamins A and C. Half number of the subjects who snacked more than the median amount consumed less carbohydrate and vitamin C than the remaining half. Furthermore, the more snack-consuming group the lower z score for height-for-age (HAZ) among schoolchildren. To improve this nutritionally vulnerable situation, consumption of snack foods should be replaced by the non-snack foods which contain much higher nutrient density; i.e. 15 times for calcium and 32 times for vitamin A. Moreover, considering high snack foods consumption of ≥7 y age group at school, appropriate school nutrition programs should be promoted.

    Full Text Available Ecotourism, as an alternative tourism, involves visiting natural areas in order to learn, to study or to carry out activities environmentally friendly, that is a tourism based on the nature experience which enables the economic and social development of local communities. Ecotourism encourages rural economics and provides benefits to income and employment generation. It is considered as an alternative for enhancing rural lifestyle and for leading positive changes in the distribution of income. One of the area which has ecotourism site in Indonesia is Karangkamulyan site, Ciamis District of West Java. There is a tourist attraction that not only offers natural beauty, history and cool atmosphere, it also serves as a place of education and research on the history in the field of archeology. This attraction should receive special attention from the local government so that the tourists and local people also get the benefits. Ecotourism can be classified as possessing public goods-type characteristics, and as such, welfare benefit estimates must utilize non-market valuation techniques. This study employs the travel cost method and contingent valuation method. Travel cost and contingent valuation methods are applied to the problem of estimating the potential consumer surplus available to tourists from ecotourism in Ciamis. The results are compared with contingent valuation analysis of willingness-to-pay of tourists in their current trip to ecotourism sites of Ciamis. The result of travel cost method indicates that tourists’ average travel cost is estimated at no more than one hundred thousand rupiahs. The contingent valuation method concludes that the tourists’ average willingness to pay in their trip to ecotourism sites of Ciamis is are about IDR 6,800 in average.

    Observation of micro-seismic events induced by intensive geothermal exploitation in a particular geothermal field, located in West Java region, Indonesia was used to detect the fracture and permeability zone. Using local monitoring seismometer network, tomographic inversions were conducted for the three-dimensional Vp, Vs, and Vp/Vs structure of the reservoir for January - December 2007, January - December 2008, and January - December 2009. First, hypocenters location was relocated using joint hypocenter determination (JHD) method in purpose to estimate best location. Then, seismic tomographic inversions were conducted using delay time tomography for dataset of every year respectively. The travel times passing through the three-dimensional velocity model were calculated using ray tracing pseudo-bending method. Norm and gradient damping were added to constrain blocks without ray and to produce smooth solution model. The inversion algorithm was developed in Matlab environment. Our tomographic inversion results from 3-years of observations indicate the presence of low Vp, low Vs, and low Vp/Vs ratio at depths of about 1 - 3 km below sea level. These features were interpreted may be related to steam-saturated rock in the reservoir area of this geothermal field. The locations of the reservoir area were supported by the data of well- trajectory, where the zones of high Vp/Vs were observed around the injection wells and the zones of low Vp/Vs were observed around the production wells. The extensive low Vp/Vs anomaly that occupies the reservoir is getting stronger during the 3-years study period. This is probably attributed to depletion of pore liquid water in the reservoir and replacement with steam. Continuous monitoring of Vp, Vs, and Vp/Vs is an effective tool for geothermal reservoir characterization and depletion monitoring and can potentially provide information in parts of the reservoir which have not been drilled.

    Surveillance of medically important mosquitoes is critical to determine the risk of mosquito-borne disease transmission. The purpose of this research was to test self-supporting, exposure-free bednet traps to survey mosquitoes. In the laboratory we tested human-baited and unbaited CDC light trap/cot bednet (CDCBN) combinations against three types of traps: the Mbita Trap (MIBITA), a Tent Trap (TENT), and a modified Townes style Malaise trap (TSM). In the laboratory, 16 runs comparing MBITA, TSM, and TENT to the CDCBN were conducted for a total of 48 runs of the experiment using 13,600 mosquitoes. The TENT trap collected significantly more mosquitoes than the CDCBN. The CDCBN collected significantly more than the MBITA and there was no difference between the TSM and the CDCBN. Two field trials were conducted in Cibuntu, Sukabumi, West Java, Indonesia. The first test compared human-baited and unbaited CDCBN, TENT, and TSM traps during six nights over two consecutive weeks per month from January, 2007 to September, 2007 for a total of 54 trapnights. A total of 8,474 mosquitoes representing 33 species were collected using the six trapping methods. The TENT-baited trap collected significantly more mosquitoes than both the CDCBN and the TSM. The second field trial was a comparison of the baited and unbaited TENT and CDCBN traps and Human Landing Collections (HLCs). The trial was carried out from January, 2008 to May, 2008 for a total of 30 trap nights. A total of 11,923 mosquitoes were collected representing 24 species. Human Landing Collections captured significantly more mosquitoes than either the TENT or the CDCBN. The baited and unbaited TENT collected significantly more mosquitoes than the CDCBN. The TENT trap was found to be an effective, light-weight substitute for the CDC light-trap, bednet combination in the field and should be considered for use in surveys of mosquito-borne diseases such as malaria, arboviruses, and filariasis.

    Sumedang Observatory (6.91°S, 107,84°E) was established in 1975 and is one of the solar observation facilities of the Space Science Center of Indonesian National Institute of Aeronautics and Space (LAPAN), located around 40 km, east part of Bandung City, West Java, Indonesia. Several instrumentations for solar and space observation such as optical telescopes, radio solar spectrograph, flux gate magnetometer, etc. are operated there, together with an ionosphere sounding system (ionosonde) that was set up later. In July 2014, a standard Callisto (Compound Astronomical Low-cost Low-frequency Instrument for Spectroscopy and Transportable Observatory) spectrometer was installed at Sumedang Observatory for solar radio activity monitoring. Callisto has been developed in the framework of IHY2007 and ISWI, supported by UN and NASA. Callisto spectrometer has observation capability in the frequency range of 45-870 MHz. The Callisto spectrometer receives signal by using a set of 21 elements log-periodic antenna, model CLP5130-1N, pointed to the Sun and equipped with a low noise pre-amplifier. With respect to the Radio Frequency Interferences (RFI) measurements, the Callisto spectrometer is operated individually in frequency ranges of 45-80 MHz and 180-450 MHz. Observation status and data flow are monitored in on-line from center office located in Bandung. The data was transferred to central database at FHNW (Fachhochschule Nordwestschweiz) server every 15 minutes to appear on e-Callisto network subsequently. A real time data transfer and data processing based on Python software also has been developed successfully to be used as an input for Space Weather Information and Forecasting Services (SWIFtS) provided by LAPAN. On 5th November 2014, Callisto spectrometer at Sumedang observed the first clear solar radio event, a solar radio burst type II corresponding to a coronal mass ejection (CME), indicated by a strong X-ray event of M7.9 that was informed on by Space Weather

    Indonesia has insufficient resources to adequately respond to the HIV/AIDS epidemic, and thus faces a great challenge in prioritizing interventions. In many countries, such priority setting processes are typically ad hoc and not transparent leading to unfair decisions. Here, we evaluated the priority setting process in HIV/AIDS control in West Java province against the four conditions of the accountability for reasonableness (A4R) framework: relevance, publicity, appeals and revision, and enforcement. We reviewed government documents and conducted semi-structured qualitative interviews based on the A4R framework with 22 participants of the 5-year HIV/AIDS strategy development for 2008-13 (West Java province) and 2007-11 (Bandung). We found that criteria for priority setting were used implicitly and that the strategies included a wide range of programmes. Many stakeholders were involved in the process but their contribution could be improved and particularly the public and people living with HIV/AIDS could be better engaged. The use of appeal and publicity mechanisms could be more transparent and formally stated. Public regulations are not yet installed to ensure fair priority setting. To increase fairness in HIV/AIDS priority setting, West Java should make improvements on all four conditions of the A4R framework.

    Tangkuban Parahu is an active stratovolcano located 17 km north of the city of Bandung in the province west Java, Indonesia. All historical eruptive activity at this volcano has been confined to a complex of explosive summit craters. About a dozen eruptions-mostly phreatic events- and 15 other periods of unrest, indicated by earthquakes or increased thermal activity, have been noted since 1829. The last magmatic eruption occurred in 1910. In late 1983, several small phreatic explosions originated from one of the summit craters. More recently, increased hydrothermal and earthquake activity occurred from late 1985 through 1986. Tilt measurements, using a spirit-level technique, have been made every few months since February 1981 in the summit region and along the south and east flanks of the volcano. Measurements made in the summit region indicated uplift since the start of these measurements through at least 1986. From 1981 to 1983, the average tilt rate at the edges of the summit craters was 40-50 microradians per year. After the 1983 phreatic activity, the tilt rate decreased by about a factor of five. Trilateration surveys across the summit craters and on the east flank of the volcano were conducted in 1983 and 1986. Most line length changes measured during this three-year period did not exceed the expected uncertainty of the technique (4 ppm). The lack of measurable horizontal strain across the summit craters seems to contradict the several years of tilt measurements. Using a point source of dilation in an elastic half-space to model tilt measurements, the pressure center at Tangkuban Parahu is located about 1.5 km beneath the southern part of the summit craters. This is beneath the epicentral area of an earthquake swarm that occurred in late 1983. The average rate in the volume of uplift from 1981 to 1983 was 3 million m3 per year; from 1983 to 1986 it averaged about 0.4 million m3 per year. Possible causes for this uplift are increased pressure within a very

    to evaluate the costs-effectiveness of scaling up community-based VCT in West-Java. the Asian epidemic model (AEM) and resource needs model (RNM) were used to calculate incremental costs per HIV infection averted and per disability-adjusted life years saved (DALYs). Locally monitored demographic, epidemiological behavior and cost data were used as model input. scaling up community-based VCT in West-Java will reduce the overall population prevalence by 36% in 2030 and costs US$248 per HIV infection averted and US$9.17 per DALY saved. Cost-effectiveness estimation were most sensitive to the impact of VCT on condom use and to the population size of clients of female sex workers (FSWs), but were overall robust. The total costs for scaling up community-based VCT range between US$1.3 and 3.8 million per year and require the number of VCT integrated clinics at public community health centers to increase from 73 in 2010 to 594 in 2030. scaling up community-based VCT seems both an effective and cost-effective intervention. However, in order to prioritize VCT in HIV/AIDS control in West-Java, issues of budget availability and organizational capacity should be addressed.

    Conceptual modeling and predictive mapping of potential for geothermal resources at the regional-scale in West Java are supported by analysis of the spatial distribution of geothermal prospects and thermal springs, and their spatial associations with geologic features derived from publicly available regional-scale spatial data sets. Fry analysis shows that geothermal occurrences have regional-scale spatial distributions that are related to Quaternary volcanic centers and shallow earthquake epicenters. Spatial frequency distribution analysis shows that geothermal occurrences have strong positive spatial associations with Quaternary volcanic centers, Quaternary volcanic rocks, quasi-gravity lows, and NE-, NNW-, WNW-trending faults. These geological features, with their strong positive spatial associations with geothermal occurrences, constitute spatial recognition criteria of regional-scale geothermal potential in a study area. Application of data-driven evidential belief functions in GIS-based predictive mapping of regional-scale geothermal potential resulted in delineation of high potential zones occupying 25% of West Java, which is a substantial reduction of the search area for further exploration of geothermal resources. The predicted high potential zones delineate about 53-58% of the training geothermal areas and 94% of the validated geothermal occurrences. The results of this study demonstrate the value of regional-scale geothermal potential mapping in: (a) data-poor situations, such as West Java, and (b) regions with geotectonic environments similar to the study area.

    Indonesia currently faces both an increasing HIV incidence and a high hepatitis B virus (HBV) burden. The objective of our study is to examine the prevalence, risk factors, and genotypic distribution of HBV infection among HIV infected patients in West Java, Indonesia. A cross sectional study was conducted among a cohort of HIV infected patients in 2008. Demographic and disease related variables were compared between HBV negative and positive patients. Logistic regression was applied to determine risk factors for HBV co-infection. HBV and HIV genotyping was performed in co-infected patients. Of 636 HIV-infected patients, the rate of HBV co-infection was 7%. The proportion of males was higher in HBV/HIV co-infected patients than in HIV mono-infected patients (93% vs. 72%, P=0.001). A history of injecting drug use (IDU), but not tattooing, was associated with HBV co-infection [P=0.035 OR 2.41 (95% CI 1.06-5.47)]. In the HIV and HBV treatment naive patients, CD4 cells counts Java. However, an increased prevalence was observed in men with a history of IDU, underlining the need for routine HBV screening and monitoring. Copyright © 2014 Elsevier B.V. All rights reserved.

    Full Text Available Background: Falls are major cause of morbidity and mortality in elderly patients. Mobility assessment is important in preventing falls in elderly. This study was conducted to determine the level of fall risk in elderly people at Karitas Cimahi Nursing Home, West Java, Indonesia by using ‘timed up and go test’(TUG. Methods:This cross-sectional descriptive study was conducted at Karitas Cimahi Nursing Home from June–November 2013. The risk of falls was categorized into two; high and low risk of falls. High risk of falls indicated when the participants complete the TUG test with time taken >10 seconds, and low risk of falls indicated when the time taken is 10 seconds. Conclusions: The level of fall risk in elderly people at Karitas Cimahi Nursing Home based on the test showed that all participants, both male and female, regardless of using assistive device have high level risk of falls.

    Full Text Available This article is concerned with the linkages between the livelihoods of tea smallholders and domestic value chains in Indonesia. Theoretically, our empirical inquiry is informed by an integration of the sustainable livelihoods approach and value chain analyses. This enables a better investigation of micro (livelihoods — meso (industry — macro (national and international trends and political economy interdependencies and interactions. In addition to value chains and socioeconomic challenges, tea smallholders in Indonesia are also confronted with droughts due to climate change and the 2015–2016 El Niño. The empirical work consisted of 36 semi-structured interviews in Girimukti village in West Java; a remote village relatively far from urban markets. Overall, our analysis demonstrates that tea smallholders are not poor, but are in a vulnerable position and remain far below the level of a stable lower-middle class. The smallholders lack human and financial capital and growing tea is not supported by horizontal coordination/social capital. In contrast, a few wealthy tea agripreneurs have established themselves as providers of inputs, intermediaries, tea drying factories, informal rural banks and village philanthropists. In other words, Girimukti is host to a process of increasing rural inequality driven by endogenous actors who are able to accumulate and concentrate tea assets and position themselves as essential nodes within the domestic tea value chain. The adaptive strategy of rural-urban migration from Girimukti to escape rural marginalisation is unattractive because of relatively low human capital levels.

    Full Text Available Bacillus pumilus is a spore-forming bacteria that is rod-shaped, gram positive, and aerobic. B. pumilus produced pumilacidins, known to have toxic effects on epithelial cells. Antibiotics were usually used to treat the disease caused by bacteria. Antibiotic typing test of B. pumilus indigenous from sewage water showed that this isolate was resistant to ampicillin and clindamycin. An alternative way was by application of bacteriophages as biocontrol agents to reduce B. pumilus in environment. The aim of this study were to isolate and characterize B. pumilus bacteriophage isolated from Ciapus River in Bogor, West Java. Bacteriophages infecting B. pumilus were isolated from river water using the double agar overlay method. Phages were defined by plaque morphology, structure, host range, and characteristic of molecular weight protein phage. Phage FBa1, FBa2, and FBa3 had narrow host range and they were specific for infecting B. pumilus. Electron microscope observation showed that phage FBa1 had icosahedral head without tail (166.67 nm in diameter, so it is called phage-like particles. Characterization of phage FBa1 by SDS-PAGE showed five proteins band. Molecular weight of FBa1 proteins was 70.9, 54.9, 33.8, 28.3, and 21.4 kDa.

    Full Text Available An extension program to control fasciolosis in cattle and buffalo was undertaken in collaboration with officers of the District of Livestock Services (DLS and farmer organizations in the Surade district of West Java. Control strategies were based on results of extensive epidemiological studies on fasciolosis in this area over the past 4 years. Recommendations included: (1 preventing animals grazing harvested rice fields adjacent to a village or cattle pen; (2 feeding stock only the top two-thirds of freshly cut rice stalks; (3 mixing cattle or buffalo faeces with manure of ducks or chicken naturally infected with Echinostoma revolutum, before using them as fertilizer in rice fields; and (4 a single treatment with triclabendazole in July, about 6 weeks after harvest of the last seasonal rice crop. Farmers were surveyed in January 1996 to determine their level of knowledge about fasciolosis. The extension program commenced in February, soon after planting the second seasonal rice crop in four villages. At first, leaflets were distributed to farmers, and posters were displayed in each village to provide basic information. Following discussions with village leaders, groups of farmers met in each village to discuss the advantages they saw in each strategy, ways they could implement them, and to identify socio-economic constraints that needed to be overcome. Taped interviews were prepared for a local radio station and the farmer groups. In August, final survey was conducted to determine the change in knowledge and attitudes that had occurred as a result of the extension program. Bennett’s hierarchy was used at each stage to evaluate the effects of inputs and activities. Farmers adopted the techniques of cutting and feeding rice-stems 2/3 above water-level, and isolating cattle from rice-fields during harvest time, as these appeared to be beneficial in social and economic terms; but they rejected the two other practices where they perceived that

    Freshwater fish demand in West Java is supported by cage aquaculture in reservoirs. Cirata Reservoir is one of three cascading hydropower reservoirs built along the Citarum River that receives domestic and industrial wastes. Water pollution by heavy metals, such as copper and lead, increases the health risk of humans who consume the fish. The study was aimed to evaluate the concentration of copper and lead in fish, specifically on Cyprinus carpio, that are widely cultivated in the Cirata Reservoir. Two sizes of fish were collected from five sampling points around floating-cage area. The liver of the fish was found to contain the highest copper level, followed by gills, skin, and muscle. In contrast, lead was also high in the liver, followed by skin, gills, and the muscle, but the copper concentration found in the tissues studied was much higher (31.111 +/- 17.911 mg/kg dry wt) than the lead content (0.290 +/- 0.346 mg/kg dry wt). The concentration of metals in smaller fish was always higher than than that in bigger fish. The metals content was also compared to those in fish exposed in a semistatic laboratory-scale study using Oreochromis niloticus. After 28 days exposure with 0.01 mg Cu/L, fish accumulated 21.53 mg Cu/kg dry wt, whereas for Pb exposure of 0.016 mg/L, fish accumulated up to 7 mg/kg dry wt. However, estimates of Cu and Pb intake from C. carpio consumption were still below the average daily intake (ADI) limit. This study suggested that monitoring of water quality and heavy metals in cultured fish is important in protecting human health.

    Full Text Available These studies were carried out in three locations representing low, medium and high altitudes in West Java to determine the effects of season, climate, management, growth and mortality on nematode parasitism in sheep and goats. Basically, the animals in each location were divided into treated and untreated groups with anthelmintics. Animals were weighed and faecal samples were collected every 2 to 4 weeks. Haemonchus contortus and Trichostrongylus spp. were the predominant species of gastrointestinal nematodes recovered from faecal cultures. In low altitude areas, faecal egg counts dropped progressively throughout the dry season and rose again with the onset of the wet season. The proportion of H. contortus larvae decreased progressively throughout the dry season and increased with the onset of the wet season, however the opposite pattern occurred with proportions of larvae of Trichostrongylus spp. In medium altitude areas, there was no consistent pattern of rising or falling faecal egg counts associated with fluctuations in rainfall. In high altitude areas, there was a trend for egg counts to increase progressively after the onset of the wet season even faecal egg counts were below 1500 epg. After treated with anthelmintics, faecal egg counts were suppressed to only few eggs in two weeks and then rose again in four week later, however in animals received medicated phenothiazine, mean egg counts were maintained below 500 epg. Treated animals in medium areas maintained low egg counts until the end of the trial. Seasonal fluctuation in weight gain of sheep was observed in low areas. Treated animals had significantly lower mortality than untreated animals but the evidence that parasitism contributed to this mortality is persuasive. It was concluded that nematode parasites cause a significant loss of production in sheep during wet season in coastal regions and in areas of rainfall throughout the year.

    The improper handling of pesticides in agriculture has caused serious health problems in many developing countries. In this study, we report the pesticide usage condition among Indonesian farmers and its association with symptoms of pesticide toxicity. A questionnaire survey on personal history regarding agricultural labor, pesticide storage and disposal, pesticide use and health history was conducted using a structured questionnaire in rural Sundanese villages in West Java, Indonesia. The most frequently used pesticides included dithiocarbamates, pyrethroids and organophosphates. In approximately 80% of sprayings, category II pesticides (World Health Organization (WHO) categorization; "moderately hazardous") were used. Many of the subject farmers worked in a highly unsafe occupational environment; protective measures and safe handling were rarely observed, whereas smoking and drinking during spraying were frequently practiced. Correlation analysis revealed that farmers who wore a long sleeve shirt and headgear showed health symptoms less frequently. Moreover, farmers who had skin contact with the spray solution during measuring or mixing (excluding the hands), who wore wet clothing (skin exposure to pesticide), and who smoked and rubbed their eyes during spraying showed more symptoms. Among these factors, headgear use, wearing wet clothing (skin exposure to pesticide), and smoking during spraying were the significant determining factors for developing health symptoms. Preventing such behaviors will be an effective method of reducing health problems among the subject farmers.

    Talaga Bodas Volcano, located near the border of Garut and Tasikmalaya regencies, West Java, Indonesia, is an active stratovolcano whose apparent shape is mainly dominated by the steep-side-cone type. Hence, monitoring Talaga Bodas Volcano to mitigate its potential hazard is extremely necessary. In this research, potential hazards are studied by observing and monitoring the deformation of the Talaga Bodas Crater using the geodetic Terrestrial Laser Scanner (TLS) tool. TLS is a relatively new positioning method in geodesy. TLS is able to obtain the position of the object points (point clouds) in a huge amount and high precision in a relatively short time. This research aims at identifying the deformation and also rock textures and structure around the Crater of Talaga Bodas. The methodology used in this research is by obtaining the scanning data using TLS in 2012 and 2015 and GPS measurements to obtain the coordinates of the reference points. The data processing methods consist of several steps, namely target to target registration, filtering, georeference, and analysis of the registered point clouds. These steps were done using the cyclone 8 software. Registered point clouds show the 3 dimension of the crater. It was found that the average values for the down-lift and up-lift deformation around the crater are about -6.4 cm and 5.1 cm, respectively. Reflected point clouds show the differences of the intensity color of the surface around the crater. This result indicates the differences of the rocks texture and structure around the crater.

    Lembang Fault is a normal fault situated at the southern flank of Tangkuban Parahu Volcano in West Java Indonesia. The fault's movement may have caused the formation of sag pond in the vicinity of its which is characterized by the soil layers of the sag pond. The characteristics of the soil can be examined based on its electrical properties such as conductivity (the inverse of resistivity) and dielectric permittivity. Direct field measurement was conducted using DC-resistivity Wenner-Schlumberger method on the sag pond as well as laboratory resistivity measurement of cores taken from the sag pond. Two resistivity crosssections were obtained after performing 2D inversion of the data which reveal that the resistivity distribution consist of a resistive layer (40-60 ohm.m) overlying a medium resistive layer (30-35 ohm.m). The third layer has relatively low resistivity of 16-25 ohm.m. At the intersection of these two lines we took coring samples down to depth of 5 m below surface and measured the electrical conductivity and dielectric permittivity for each 1 cm of sample using EM-50 data logger. Results from both field and laboratory measurement were analysed to get a better understanding of the sag pond.

This research was of a retrospective and cross sectional design. This research was conducted in Subang Farming Regency, West Java. There are two types of population (farmer households, namely, those of horticultural region and those of rice field region. The sample size at each location was 261 households, so the total sample was 522 households.  The results of this research show that in general the frequency and quantity of food consumed by the non poor households are relatively better than those of the poor households. Further, as the centers of agricultural production, both regions (rice and horticulture will produce certain foods in abundance and will affect the patterns of food consumption among the local community and households.  Children’s nutritional status is in general of good category (based on W/A and H/A. Husband’s and wives’ nutritional status is normal. The length of upper respiratory tract infection on wives and children is quite low (.

    In the last several decades we have been realized for the Global Climate Change situation. Some indicators are worldwide increasing temperature, decreasing volume of ice in Antarctica, and the sea level rise. Relating to the decreased of ice volume and the sea level rise, this situation has been predicted to endanger the living at the coastal area in the future. Prediction models have shown some coastal cities area would suffer flood by tidal inundation and even permanent flooding. Coincidently, today in the North West of Demak District Central Java Indonesia we literally can see the early picture of Global Climate Change impact to the coastal areas as mention. The occurrence of tidal inundation in this area was recognized at least in the early 2000 and even earlier, and in the recent years the tidal inundation comes not only at a high tide but even at the regular tide, and in fact some of this area are obviously sinking to the sea through times. This early picture is truly showing a disaster. Adaptation has been made in facing the disaster such as increasing the house and infrastructures, and built dyke. We have been done some investigations to this area by field observations (mapping the flooded area, interviewing people and seeing the adaptations, conduct GPS measurement to see deformation, etc.), gather information from digital media and also using remotely time series of high resolution satellite image data to mapping the tidal inundation in this area. We noted people increased their house and the local goverment elevated the road and the bridge, etc. regulary over less decade periode. Our conclusions said that the adaptation only made temporaly since the sea level keep rising worsening by the land subsidence significantly.

    Land use patterns and the occurrence of Anopheles species larvae were studied in Sukabumi District, West Java, Indonesia, from October 2004 to September 2005. Two land use maps derived using remote sensing were used. One map derived from Quickbird satellite images of 150 km2 of the Simpenan and Ciemas subdistricts (106 degrees 27' 53"-106 degrees 38' 38" E and 6 degrees 59' 59"-7 degrees 8' 46" S) in Sukabumi and one using ASTER images covering 4,000 km2 of Sukabumi District from 106 degrees 22' 15"-107 degrees 4' 1" E and 6 degrees 42' 50" - 7 degrees 26' 13" S. There was a total of 11 Anopheles spp. collected from 209 sampling locations in the area covered by the Quickbird image and a total of 15 Anopheles spp. collected from 1,600 sampling locations in the area covered by the ASTER map. For the area covered by the land use maps, ten species were found to have statistically positive relationships between land use class and species presence: Anopheles aconitus, An. annularis, An. barbirostris. An. flavirostris, An. insulaeflorum, An. kochi, An. maculatus, An. subpictus, An. sundaicus, and An. vagus. Quickbird and ASTER satellite images both produced land maps that were adequate for predicting species presence in an area. The land use classes associated with malaria vector breeding were rice paddy (An. aconitus, An. subpictus), plantation located near or adjacent to human settlements (An. maculatus), bush/shrub (An. aconitus, An. maculatus, An. sundaicus), bare land, and water body land use on the coast located < or = 250 m of the beach (An. sundaicus). Understanding the associations of habitat and species in one area, predictions of species presence or absence can be made prior to a ground survey allowing for accurate vector survey and control planning.

    A 12-mo ecological study of the spatial-temporal distribution of immature stages of Anopheles species was conducted in Sukabumi District, West Java, Indonesia. The study characterized 1,600 sites from a contiguous coastal and hill zone (0-800-m elevation) of which 64% contained Anopheles larvae. Principal component and multiple logistic regression analyses identified ecological parameters associated with presence of nine [Anopheles aconitus Doenitz, Anopheles annularis Van de Wulp, Anopheles barbirostris Van der Wulp, Anopheles flavirostris (Ludlow), Anopheles insulaeflorum (Swellengrebel and Swellengrebel de Graaf), Anopheles kochi Doenitz, Anopheles maculatus Theobald, Anopheles sundaicus (Rodenwaldt), and Anopheles vagus Doenitz] of 15 Anopheles species collected. Combined data for all nine species showed increased Anopheles presence associated with wet season periods and higher elevation habitats exhibiting reduced tree canopy coverage, higher water temperatures, and shallower water depths. Habitat variables measured included topography (elevation), water conditions (temperature, pH, salinity depth, and velocity), habitat characteristics (substrate and canopy cover), density and type of aquatic vegetation coverage (riparian, floating, and emergent), and distance from nearest human habitation. Significant relationships were found for nine species when using all habitats in the analysis. Habitat characteristics for three species were refined. An. aconitus and An. barbirostris were associated with higher elevation rice, Oryza savita L., paddies with relatively shallow water depths, higher water temperatures, higher acidity and salinity concentrations, and a greater average distance from human habitation. An. vagus presence in rice paddies was associated with lower elevation fields, deeper and cooler water, less acidic and saline conditions, and habitats closer to human dwellings. Overall, the distribution of Anopheles species in Sukabumi was found to be nonrandom

    To investigate qualitatively and quantitatively the performance of a programme for managing the child contacts of adult tuberculosis patients in Indonesia. A public health evaluation framework was used to assess gaps in a child contact management programme at a lung clinic. Targets for programme performance indicators were derived from established programme indicator targets, the scientific literature and expert opinion. Compliance with tuberculosis screening, the initiation of isoniazid preventive therapy in children younger than 5 years, the accuracy of tuberculosis diagnosis and adherence to preventive therapy were assessed in 755 child contacts in two cohorts. In addition, 22 primary caregivers and 34 clinic staff were interviewed to evaluate knowledge and acceptance of child contact management. The cost to caregivers was recorded. Gaps between observed and target indicator values were quantified. THE GAPS BETWEEN OBSERVED AND TARGET PERFORMANCE INDICATORS WERE: 82% for screening compliance; 64 to 100% for diagnostic accuracy, 50% for the initiation of preventive therapy, 54% for adherence to therapy and 50% for costs. Many staff did not have adequate knowledge of, or an appropriate attitude towards, child contact management, especially regarding isoniazid preventive therapy. Caregivers had good knowledge of screening but not of preventive therapy and had difficulty travelling to the clinic and paying costs. The study identified widespread gaps in the performance of a child contact management system in Indonesia, all of which appear amenable to intervention. The public health evaluation framework used could be applied in other settings where child contact management is failing.

    Mount Ciremai's spring zone exhibits complex relationships among modern and solitaire topography, lava flow geometries, and groundwater flow patterns. As many as 161 springs were observed (140 on east slope and 21 on west slope). The majority of springs show hypothermal signal, on both slopes. TDS-Water temperature shows more homogeneous plot on east slope, representing identical geological control on the three volcanic aquifers. Scattered points on west slope signify heterogeneous geological control, including faults from previous geophysical mapping. Elevation-EC chart on both slopes show larger EC readings on lower elevation. East slope plot shows value range from 19 to 200 μSiemens with scattered anomaly from 300 to 620 μSiemens, indicating less mineralization in the system, from geothermal or older marine sediments. West slope plots show similar range with EC reading not more than 300 μSiemens, indicating less influence of additional mineralization.Elevation-Q chart demonstrates scattered points on east slope indicating there are at least two systems: captive system aquifer with no water leakage from the above aquifer and open system aquifer with leakage between aquifers. West slope illustrates more regular trend indicating interaction between aquifers towards lower elevation and positive break demonstrating possible fault boundary. In young volcanic deposits with large amounts of annual precipitation, high recharge rates coupled with fractured volcanic aquifers that have large near-surface hydraulic conductivity lead to broad systems. The aquifer is locally guided by the extent of permeable lava flows. The air and water temperature in most of the springs are close to atmospheric, implying shallow flow paths. Water discharging at large and hypothermal springs have limited interaction with geothermal system. Anomalously large springs suggest that topographically defined watersheds may not correspond to aquifer boundaries. The field observations reveal that

    Suhari, S.; Siebenhüner, M.

    The demand on land and natural resources in the Greater Bandung area increases rapidly with increasing population and economic growth. Land use changes and over-exploitation of natural resources have significantly caused negative environmental impacts. In the period 1989-1993, an Indonesian-German technical cooperation project between the Directorate of Environmental Geology (Indonesia) and the Federal Institute for Geosciences and Natural Resources (Germany) has been conducting a study to improve the conservation and management of the natural resources for regional planning in the Bandung Basin. The Bandung Basin consists of a plain which is surrounded by a mountainous chain. The mountainous area is mostly dominated by Quaternary volcanic products such as lava, breccia, agglomerate, lahar, tuff, and andesite intrusions. The plain comprises thick alluvial deposits of river and lacustrine origin. Tertiary sediments only cover the western part of the basin. The Quaternary volcanic products do not only produce fertile agricultural soils but also are the important source of various construction materials and act as groundwater recharge. From the environmental geology point of view, the physical development,of the Greater Bandung area faces various constraints. These include conflict among urban development, agricultural land, groundwater protection, extraction of mineral resources, and potential waste disposal sites. In addition, some areas are restricted for development due to: (a) their poor foundation characteristics; (b) location in flood prone areas; and (c) geological hazards such as landslides and lahar flows. Operation of many existing and abandoned waste disposal dumping facilities in geologically unfavorable areas has contaminated both the groundwater and surface water. Improper exploitation technique in many quarries and pits has also endangered the environment, such as destabilization of slope, increasing danger of landslides and erosion, and increasing

    West Java, part of the Sunda Arc, has relatively high seismicity due to subduction activity and faulting. The first step of tomography study in order to infer the geometry of the structure beneath West Java is to conduct precise earthquake hypocenter determination. In this study, we used earthquake waveform data taken from the regional Meteorological, Climatological, Geophysical Agency (BMKG) network from South Sumatra to central Java. We have repicked P and S arrival times from about 800 events in the period from April 2009 to December 2015. We selected the events which have azimuthal gap program to determine the earthquake hypocenters. The hypocenter location results give better clustering earthquakes which are correlated well with geological structure in the study region. We also compared our results with BMKG catalog data and found that the average hypocenter location difference is about 12 km in latitude direction, 9.5 km in longitude direction, and the average focal depth difference is about 19.5 km. For future studies, we will conduct tomographic imaging to invert 3-D seismic velocity structure beneath the western part of Java.

    The objective of this study is to determine boundary and how to know surrounding area between Lembang Fault and Cimandiri fault. For the detailed study we used three methodologies: (1). Surface deformation modeling by using Boundary Element method and (2) Controlled Source Audiomagneto Telluric (CSAMT). Based on the study by using surface deformation by using Boundary Element Methods (BEM), the direction Lembang fault has a dominant displacement in east direction. The eastward displacement at the nothern fault block is smaller than the eastward displacement at the southern fault block which indicates that each fault block move in left direction relative to each other. From this study we know that Lembang fault in this area has left lateral strike slip component. The western part of the Lembang fault move in west direction different from the eastern part that moves in east direction. Stress distribution map of Lembang fault shows difference between the eastern and western segments of Lembang fault. Displacement distribution map along x-direction and y-direction of Lembang fault shows a linement oriented in northeast-southwest direction right on Tangkuban Perahu Mountain. Displacement pattern of Cimandiri fault indicates that the Cimandiri fault is devided into two segment. Eastern segment has left lateral strike slip component while the western segment has right lateral strike slip component. Based on the displacement distribution map along y-direction, a linement oriented in northwest-southeast direction is observed at the western segment of the Cimandiri fault. The displacement along x-direction and y-direction between the Lembang and Cimandiri fault is nearly equal to zero indicating that the Lembang fault and Cimandiri Fault are not connected to each others. Based on refraction seismic tomography that we know the characteristic of Cimandiri fault as normal fault. Based on CSAMT method th e lembang fault is normal fault that different of dip which formed as

    The integrated management of childhood illness (IMCI) is a comprehensive approach to child health, which has been adopted in Indonesia since 1997. This study aims to provide an overview of IMCI implementation at community health centres (puskesmas) in West Java province, Indonesia. Data were derived from a cross-sectional study conducted in 10 districts of West Java province, from November to December 2012. Semi-structured interviews were used to obtain information from staff at 80 puskesmas, including the heads (80 informants), pharmacy staff (79 informants) and midwives/nurses trained in IMCI (148 informants), using semi-structured interviews. Quantitative data were analysed using frequency tabulations and qualitative data were analysed by identifying themes that emerged in informants' responses. Almost all (N = 79) puskesmas implemented the IMCI strategy; however, only 64% applied it to all visiting children. Several barriers to IMCI implementation were identified, including shortage of health workers trained in IMCI (only 43% of puskesmas had all health workers in the child care unit trained in IMCI and 40% of puskesmas conducted on-the-job training). Only 19% of puskesmas had all the essential drugs and equipment for IMCI. Nearly all health workers acknowledged the importance of IMCI in their routine services and very few did not perceive its benefits. Lack of supervision from district health office staff and low community awareness regarding the importance of IMCI were reported. Complaints received from patients'families were generally related to the long duration of treatment and no administration of medication after physical examination. Interventions aiming to create local regulations endorsing IMCI implementation; promoting monitoring and supervision; encouraging on-the-job training for health workers; and strengthening training programmes, counselling and other promotional activities are important for promoting IMCI implementation in West Java province

    Java has been experiencing deforestation due to high population pressure. A lot of natural forests which play an important role as wildlife habitat are loss. The remaining natural forest distribute in mountainous areas in the form natural conservation area, meanwhile the others have been converted into settlement andinfrastructure, food crops, cash crops plantation, estate and private forest plantation. Javan langur (Presbytiscomata) is an endemic species of Java and used to utilize natural forest as their habitat. However, in a recent observation the species isfound inside plantation forest in Kuningan district, West Java. This is a unique finding, due to the fact that a plantation forest is not suitable habitat for Javan langur. The research is aimed to develop Habitat Suitability for this species based on physical, biological and human disturbance factors. Data on Javan langur presence and its habitat component were derived from field observation and secondary data/map. Result showed HSI could be developed based on 4 PC and showed that the study area mostly is occupied by low HIS Index or not suitable area for surili.

    This paper assesses the presence of navigational hazards due to underestimation of charted depths originated from an establishment of a sea-level-related reference plane, i.e. datum. The study domain is situated in one of Indonesia's densest marine traffic, SW Java Sea, Indonesia. The assessment is based on the comparison of the authorized Chart Datum (CD), being uniformly located at 0.6 m below Mean Sea Level (MSL), and a spatially varying Lowest Astronomical Tide (LAT) generated for the purpose of this research. Hazards are considered here as the deviation of LAT from CD and quantified as the ratio of LAT -CD deviation with respect to the allowable Total Vertical Uncertainty (TVU), i.e. the international standard for accuracy of depth information on nautical charts. Underestimation of charted depth is expected for the case that LAT falls below CD. Such a risk magnifies with decreasing depths, as well as the increasing volume of traffic and draught of the vessel. It is found that most of the domain is in the interior of risk-free zone from using uniform CD. As much as 0.08 and 0.19 parts of the area are in zones where the uncertainty of CD contributes respectively to 50% and 30% of Total Vertical Uncertainty. These are zones where the hazard of navigation is expected to increase due to underestimated lowest tidal level.

    Full Text Available Abstract Background Trained birth attendants at delivery are important for preventing both maternal and newborn deaths. West Java is one of the provinces on Java Island, Indonesia, where many women still deliver at home and without the assistance of trained birth attendants. This study aims to explore the perspectives of community members and health workers about the use of delivery care services in six villages of West Java Province. Methods A qualitative study using focus group discussions (FGDs and in-depth interviews was conducted in six villages of three districts in West Java Province from March to July 2009. Twenty FGDs and 165 in-depth interviews were conducted involving a total of 295 participants representing mothers, fathers, health care providers, traditional birth attendants and community leaders. The FGD and in-depth interview guidelines included reasons for using a trained or a traditional birth attendant and reasons for having a home or an institutional delivery. Results The use of traditional birth attendants and home delivery were preferable for some community members despite the availability of the village midwife in the village. Physical distance and financial limitations were two major constraints that prevented community members from accessing and using trained attendants and institutional deliveries. A number of respondents reported that trained delivery attendants or an institutional delivery were only aimed at women who experienced obstetric complications. The limited availability of health care providers was reported by residents in remote areas. In these settings the village midwife, who was sometimes the only health care provider, frequently travelled out of the village. The community perceived the role of both village midwives and traditional birth attendants as essential for providing maternal and health care services.

    West Java Province is the most landslide risky area in Indonesia owing to extreme geo-morphological conditions, climatic conditions and densely populated settlements with immense completed and ongoing development activities. So, a landslide susceptibility map at regional scale in this province is a fundamental tool for risk management and land-use planning. Logistic regression and Artificial Neural Network (ANN) models are the most frequently used tools for landslide susceptibility assessment, mainly because they are capable of handling the nature of landslide data. The main objective of this study is to apply logistic regression and ANN models and compare their performance for landslide susceptibility mapping in volcanic mountains of West Java Province. In addition, the model application is proposed to identify the most contributing factors to landslide events in the study area. The spatial database built in GIS platform consists of landslide inventory, four topographical parameters (slope, aspect, relief, distance to river), three geological parameters (distance to volcano crater, distance to thrust and fault, geological formation), and two anthropogenic parameters (distance to road, land use). The logistic regression model in this study revealed that slope, geological formations, distance to road and distance to volcano are the most influential factors of landslide events while, the ANN model revealed that distance to volcano crater, geological formation, distance to road, and land-use are the most important causal factors of landslides in the study area. Moreover, an evaluation of the model showed that the ANN model has a higher accuracy than the logistic regression model.

    It is unclear whether habitat degradation correlates with tolerance of marine invertebrates to abiotic stress. We therefore tested whether resistance to climate change-related stressors differs between populations of the green mussel Perna viridis from a heavily impacted and a mostly pristine site in West Java, Indonesia. In laboratory experiments, we compared their oxygen consumption and mortality under lowered salinity (-13 and -18 units, both responses), hypoxia (0.5 mg/l, mortality only) and thermal stress (+7 °C, mortality only). Mussels from the eutrophied and polluted Jakarta Bay showed a significantly smaller deviation from their normal oxygen consumption and higher survival rates when stressed than their conspecifics from the unaffected Lada Bay. This shows that human induced habitat degradation correlates with mussel tolerance to environmental stress. We discuss possible mechanisms - e.g. the selection of tolerant genotypes or habitat-specific differences in the nutritional status of the mussels - that could explain our observation.

    Indonesia is the country with the 4th largest population in the worlds; the population reached more than 237 million people. With rice as the staple food for more than 95 percent of the population, there is an important role of paddy field in Indonesian food security. Actually, paddy field in Java has produced 52,6% of the total rice production in Indonesia, showing the very high dependence of Indonesia on food production from paddy fields in Java island. Karawang Regency is one of the regions in West Java Province that contribute to the national food supply, due to its high soil fertility and its high extent of paddy field. Dynamics of land use change in this region are high because of its proximity to urban area; this dynamics has led to paddy field conversion to industry and residential landuse, which in turn change the regional rice production capacity. Decreasing paddy field landuse in this region could be serve as an example case of the general phenomena which occurred in Javanese rice production region. The objective of this study were: (i) to identify the suitable area for paddy field, (ii) to modelize the decreasing of paddy field in socio-economic context of the region, and (iii) to plan the spatial priority area of paddy field protection according to model prediction. A land evaluation for paddy was completed after a soil survey, while IKONOS imagery was analyzed to delineate paddy fields. Dynamic system model of paddy field land use is built, and then based on the model built, the land area of paddy field untill 2040 in some scenarios was developped. The research results showed that the land suitability class for paddy fields in Karawang Regency ranged from very suitable (S1) to marginally suitable (S3), with various land characteristics as limiting factors. The model predicts that if the situation of paddy field land use change continues in its business as usual path, paddy field area that would exist in the region in 2040 will stay half of the recent

    The Basic Health Research of the Ministry of Health Indonesia in 2008 reported that the single most important cause of death was stroke, in both urban and rural populations. The risk factors underlying the cause of death are associated with hypertension, obesity and dyslipidemia. The purpose of this study was to determine the mean intake of trans fatty acids and its relation to dyslipidemia in a sample of Indonesian adults. A cross-sectional study was conducted on a total of 180 adult male and female respondents aged 35-60 years living in rural and urban areas of Depok city, West Java. Dietary intake was assessed by means of 24-hour recall and semi-quantitative FFQ. The mean intake of trans fatty acids was 0.48% of total calories (urban 0.40% and rural 0.55%). The prevalence of dyslipidemia in the rural and urban subjects were 61.1% and 66.7%, respectively. There was a statistically significant relationship between trans fatty acids intake and hypercholesterolemia and hypertriglyceridemia. The intake of trans fatty acid among the Indonesian adults studied was half the recommended level. The high prevalence of dyslipidemia found indicates the need for intervention to reduce the rising incidence of cardiovascular diseases in Indonesia.

    Due to the high burden of pneumonia in Indonesia, the inclusion of pneumococcal conjugate vaccine (PCV) into Indonesia's National Immunization Program (NIP) is recommended by World Health Organization. Prior to the introduction of new vaccines, it is imperative to assess the perceptions of the public and medical community about the disease and the vaccine. The purpose of this qualitative study was to explore the knowledge, perceptions, and attitudes of mothers and health care providers (HCPs) toward PCV in Bandung, West Java, Indonesia. Fifty-five respondents (26 mothers and 29 HCPs) were interviewed at public and private health care facilities in Bandung using semi-structured interviews in May-June 2011. Data were analyzed manually according to pre-defined themes. Although most mothers had low knowledge about PCV, did not perceive themselves as susceptible to the disease, perceived that cost was the main barrier to PCV access, and obtained little information on PCV, they considered pneumonia as a severe disease and a priority health problem, perceived benefits of the vaccine, and were likely to adopt it. Similarly, knowledge about PCV among most HCPs was limited. Despite perceiving cost as the main barrier, most HCPs perceived benefits of the vaccine, susceptibility and severity of the disease, regarded pneumonia as a priority health problem, and were likely to suggest the new vaccination. Despite the poor knowledge of mothers and HCPs about PCV, they are aware of the high burden of pneumonia and the need for a vaccine in the NIP. Perceived severity and benefits among mothers, and, additionally, perceived susceptibility among HCPs were manifested in the willingness to accept PCV. The findings would contribute to better understanding the factors, which could support decision-making about vaccine introduction, and be utilized for developing suitable messages for mothers and HCPs.

    Gede Volcano (West Java) is part of an andesitic stratovolcano complex consisting of Pangrango in the north-west and Gede in the south-east. The last recorded eruptive activity was a phreatic subvolcanian ash eruption in 1957. Current activity is characterized by episodic swarms at 2-4 km depth, and low-temperature (~160°C) crater degassing in two distinct summit crater fumarolic areas. Hot springs occur in the saddle between the Gede and Pangrango edifice, as well as on the NE flank base. The most recent eruptive events produced pyroclastic material, their flow deposits concentrate toward the NE. A collaborative effort between the Center for Volcanology and Geological Hazard Mitigation (CVGHM), Geological Agency and the Earth Observatory of Singapore (EOS) is since 2010 aimed at upgrading the geophysical and geochemical monitoring network at Gede Volcano. To support the monitoring instrumentation upgrades under way, surveys of soil CO2 degassing have been performed on the flanks of Gede, in circular and radial traverses.The goal was to establish a spatial distribution of flank CO2 fluxes, and to allow smart siting for continuous gas monitoring stations. Crater fluxes were not surveyed, as its low-temperature hydrothermal system is likely prone to large hydraulic changes in this tropical environment, resulting in variable permeability effects that might mask signals from deeper reservoir or conduit degassing. The high precipitation intensity in the mountains of tropical Java pose challenges to this method, since soil gas permeability is largely controlled by soil moisture content. Simultaneous soil moisture measurements were undertaken. The soil CO2 surveys were carried out using a LI-8100A campaign flux chamber instrument (LICOR Biosciences, Lincoln, Nebraska). This instrument has a very precise and highly stable sensor and an atmospheric pressure equilibrator, making it highly sensitive to low fluxes. It is the far superior choice for higher precision low

    In the present study, we assessed the composition of Bacteria in four biotopes namely sediment, seawater and two sponge species (Stylissa massa and Xestospongia testudinaria) at four different reef sites in a coral reef ecosystem in West Java, Indonesia. In addition to this, we used a predictive metagenomic approach to estimate to what extent nitrogen metabolic pathways differed among bacterial communities from different biotopes. We observed marked differences in bacterial composition of the most abundant bacterial phyla, classes and orders among sponge species, water and sediment. Proteobacteria were by far the most abundant phylum in terms of both sequences and Operational Taxonomic Units (OTUs). Predicted counts for genes associated with the nitrogen metabolism suggested that several genes involved in the nitrogen cycle were enriched in sponge samples, including nosZ, nifD, nirK, norB and nrfA genes. Our data show that a combined barcoded pyrosequencing and predictive metagenomic approach can provide novel insights into the potential ecological functions of the microbial communities. Not only is this approach useful for our understanding of the vast microbial diversity found in sponges but also to understand the potential response of microbial communities to environmental change.

    The Sundanese inhabiting West Java, the second largest ethnic group in Indonesia, are characterized by a high prevalence of child malnutrition, together with high fertility. Based on an anthropometric measurement and interview survey of 310 children aged 5-12 years in a rural Sundanese village, this study examined the relative significance of the effects of eight biological, eight socioeconomic status (SES) and four health behavioural factors on their Z scores for height-for-age (HAZ) and weight-for-age (WAZ) in particular. Three biological factors, i.e. birth interval, birth weight and mother's body weight, and one SES factor, i.e. mother's occupation, were selected as the predictors of the two Z scores by regression analysis, indicating more significant effects of the biological factors than the other factors. This pattern is judged to occur in less-developed and high-fertility populations. Since these two Z scores were worse in the subject children than in the under-5-year-old children from the same village, more attention should be paid to the long-lasting effects of birth-related biological factors up to pre-adolescent ages, as an insufficient nutritional status tends to damage growth and health in adolescence and adulthood.

    The immunodominant 33/35kDa antigen of a Theileria isolate from West Java, Indonesia, was characterised and immuno-affinity purified by use of a monoclonal antibody, KUL-a4, and was shown to be representative of the T. orientalis/sergenti/buffeli group. The aminoterminal sequence of the purified 35kDa peptide (20 residues) was determined by automated Edman degradation and found to correspond to the predicted amino acid sequence of a prospective p33 gene previously sequenced from the same isolate. The cleavage site of a putative signal peptide was identified and conforms the (-3, -1) rule for signal peptidases. The existence of dimeric and trimeric forms of the p33/35 antigen is hypothesised from Western blot profiles. KUL-a4 appeared specific for the T. orientalis/sergenti/buffeli group. It did not recognise in indirect fluorescence antibody test (IFAT), intraerythrocytic bodies of Anaplasma marginale or piroplasms and schizonts of T. mutans, T. parva and T. annulata, whereas cattle antisera raised to these species showed cross-reactivity in IFAT. It however, appeared weakly cross-reactive in Western blot and ELISA, with the 34kDa piroplasm antigen of one T. annulata (Gharb) isolate. The present study indicates that the isolated antigen belongs to the p33/34 antigen family described within the T. sergenti/orientalis/buffeli group, and documents the group-specificity of one of its epitopes.

    Mercury pollution is caused by artisanal and small-scale gold mining (ASGM) operations along the Cikaniki River (West Java, Indonesia). The atmosphere is one of the primary media through which mercury can disperse. In this study, atmospheric mercury levels are estimated using the native epiphytic fern Asplenium nidus complex (A. nidus) as a biomonitor; these estimates shed light on the atmospheric dispersion of mercury released during mining. Samples were collected from 8 sites along the Cikaniki Basin during September-November, 2008 and September-November, 2009. The A. nidus fronds that were attached to tree trunks 1-3m above the ground were collected and measured for total mercury concentration using cold vapor atomic absorption spectrometry (CVAAS) after acid-digestion. The atmospheric mercury was collected using porous gold collectors, and the concentrations were determined using double-amalgam CVAAS. The highest atmospheric mercury concentration, 1.8 × 10(3) ± 1.6 × 10(3) ngm(-3), was observed at the mining hot spot, and the lowest concentration of mercury, 5.6 ± 2.0 ngm(-3), was observed at the remote site from the Cikaniki River in 2009. The mercury concentrations in A. nidus were higher at the mining village (5.4 × 10(3) ± 1.6 × 10(3) ngg(-1)) than at the remote site (70 ± 30 ngg(-1)). The distribution of mercury in A. nidus was similar to that in the atmosphere; a significant correlation was observed between the mercury concentrations in the air and in A. nidus (r=0.895, P<0.001, n=14). The mercury levels in the atmosphere can be estimated from the mercury concentration in A. nidus using a regression equation: log (Hg(A.nidu)/ngg(-1))=0.740 log (Hg(Air)/ngm (-3)) - 1.324.

    School lunch is not provided in public elementary schools in Indonesia, and students frequently buy and eat snacks at school. We hypothesized that providing a traditional Sundanese meal as school lunch would be beneficial for children in rural West Java. To test this hypothesis, we evaluated the effect of a 1-month school lunch intervention aiming at sustainability and based on children's nutritional intake, hemoglobin and hematocrit levels, and body mass index (BMI). A lunch (including rice, vegetable dish, animal protein dish, plant protein dish, and fruit) containing one-third of the recommended daily allowance of energy was offered every school day for 1 month, targeting 68 fourth-grade elementary schoolchildren. At baseline, the prevalence of anemia was 33.3%. The prevalence of stunting and underweight were 32.4% and 2.9%, respectively, whereas that of overweight and obesity combined was 17.6%, indicating a double burden of malnutrition among the subjects. During the intervention, intakes of protein (p < 0.05), calcium (p < 0.05), and vitamin C (p < 0.001) significantly increased, while that of fat significantly decreased (p < 0.001). After the intervention, hemoglobin (p < 0.05) and hematocrit (p < 0.05) levels were significantly improved, thereby almost halving the rate of anemia. These changes were significantly larger in the baseline anemic group than the non-anemic group (p < 0.01). BMI significantly increased in the baseline underweight/normal group (p < 0.001) but not in the overweight/obese group. The school lunch intervention significantly improved nutritional intakes and health statuses, implying its potential for reducing anemia and resolving the double burden of malnutrition among rural Indonesian schoolchildren.

    The purpose of this study was to determine the association of potential risk factors to the spread and maintenance of the highly pathogenic avian influenza (HPAI) H5N1 virus in poultry and humans at the district level in West Java Province, Indonesia. The association of demography and environmental risk factors including poultry density, human density, road density, percentage of paddy field, and percentage of swamp, dyke and pond with both HPAI human cases and HPAI outbreaks in poultry were assessed using a descriptive epidemiological design. We also assessed the association of HPAI outbreaks in poultry with HPAI human cases. Poisson regression (generalized linear modeling and generalized estimating equations) was used to analyze the data corrected for over-dispersion. There were 794 HPAI outbreaks in poultry covering 24 of the 25 districts in our study during 2003-2008 and 34 HPAI human cases involving 12 districts during 2005-2008. We found that two risk factors--poultry density and road density--had a statistically significant correlation with the number of HPAI outbreaks in poultry. The number of poultry outbreaks had a negative association with poultry density (29% effect) and a positive association with road density (67% effect). The number of human cases was significantly associated with the number of poultry outbreaks (34% effect), but with none of the other risk factors considered. We conclude that the most effective way to prevent human HPAI cases is to intervene directly in the poultry sector. Our study further suggests that implementing preventive measures in backyard chicken farming and limiting transport of live poultry and their products are promising options to this end.

    Full Text Available http://dx.doi.org/10.17014/ijog.vol2no1.20072Papandayan is a strato volcano situated in West Java, Indonesia. After the last magmatic eruptionin 1772, only few phreatic explosions have been occurring. At the present time, the activity is centeredin the northeast crater manifested by the presence of fumaroles and hot springs. In November 2002an explosive eruption occurred and ejected ash and altered rocks. Study of the altered rocks revealedthat an advanced argillic alteration took place in the hydrothermal system by an interaction betweenacid fl uids and rocks. Four zones of alteration have been formed as a limited extension along faults oracross permeable structures at different levels beneath the active crater of the volcano.Two types of acid fl uids are distinguished in the crater of the Papandayan Volcano: (1 acidsulphate-chloride water with pH values between 1.6 and 4.6, and (2 acid sulphate water with pHvalues between 1.2 and 2.5. The samples collected after the eruption revealed an increase in the SO4/Cl and Mg / Cl ratios. This evolution is likely explained by an increase in the neutralization of acidfl uids which tends to show that water-rock interactions were more signifi cant after the eruption. Thechanges in chemistry observed in 2003 were the consequence of the opening of new fractures whereunaltered or less altered volcanic rocks were in contact with the ascending acid water. The high δ34Svalues (9-17‰ observed in the acid sulphate-chloride water before the November 2002 eruptionsuggest that dissolved sulphates were mainly formed by the disproportionation of magmatic SO2. Onthe other hand, the low δ34S values (-0.3-7 ‰ observed in acid sulphate-chloride water sampled afterthe eruption suggest that the origin of dissolved sulphates for these waters is the surfi cial oxidation ofhydrogen sulphide.

    Tangkuban Parahu is one of the active volcano in Indonesia located about 15 km northern part of Bandung city. The objective of this study is to investigate the seismic activity in the time periods of January 2013 to December 2013. First, we identified seismic events induced by volcano-tectonic activities. These micro-earthquake events were identified as having difference of P-wave and S-wave arrival times less than three seconds. Then, we constrained its location of hypocenter to locate the source of the activities. Hypocenter determination was performed using adaptive simulated annealing method. Using these results, seismic tomographic inversions were conducted to image the three-dimensional velocity structure of Vp, Vs, and the Vp/Vs ratio. In this study, 278 micro-earthquake events have been identified and located. Distribution of hypocenters around Tangkuban Parahu volcano forms an alignment structure and may be related to the stress induced by magma below, also movement of shallow magma below Domas Crater. Our preliminary tomographic inversion results indicate the presences of low Vp, high Vs, and low Vp/Vs ratio that associate to accumulated young volcanic eruption products and hot material zones.

    We analyze the spatial pattern of active deformation in Java, Indonesia with the aim of characterizing the deformation of the upper plate of the subduction zone in this region. The lack of detailed neotectonic studies in Java is mostly because of its relatively low rate of deformation in spite of significant historical seismic activity. In addition, the abundance of young volcanic materials as well as the region's high precipitation rate and vegetation cover obscure structural relationships and prevent reliable estimates of offset along active faults as well as exhumed intra-arc faults. Detailed maps of active faults derived from satellite and field-based neotectonic mapping, paleoseismic data, as well as new data on the fault kinematics and estimates of orientation of principal stresses from volcano morphology characterize recently active faults and folds. The structures in West Java are dominated by strike-slip faulting, while Central and northern part of East Java are dominated by folds and thrusting with minor normal faulting. The structures vary in length from hundreds meters to tens of kilometers and mainly trend N75°E, N8°E with some minor N45°W. Our preliminary mapping indicates that there are no large scale continuous structures in Java, and that instead deformation is distributed over wide areas along small structures. We established several paleoseismic sites along some of the identified structures. We excavated two shallow trenches along the Pasuruan fault, a normal fault striking NW-SE that forms a straight 13 km scarp cutting Pleistocene deltaic deposits of the north shore of East Java. The trenches exposed faulted and folded fluvial, alluvial and colluvial strata that record at least four ground-rupturing earthquakes since the Pleistocene. The Pasuruan site proves its potential to provide a paleoseismic record rarely found in Java. Abundant Quaternary volcanoes are emplaced throughout Java; most of the volcanoes show elongation in N100°E and N20

It has a lot of mountain area which is disaster-prone area for landslide. We have collected landslide data in 305 villages in Ponorogo and make it to be Hazards Index. Then we also calculate Vulnerability Index, Economic Loss index, Environmental Damage Index and Capacity Index. The risk analysis map is composed of three components H (Hazards), V (Vulnerability, Economic Loss index, Environmental Damage Index) and C (Capacity Index). The method is based on regulations of National Disaster Management Authority (BNPB) number 02/2012 and number 03/2012. It has three classes of risk index, i.e. Low, Medium and High. Ponorogo city has a medium landslide risk index.

    Antenatal, delivery and postnatal care services are amongst the recommended interventions aimed at preventing maternal and newborn deaths worldwide. West Java is one of the provinces of Java Island in Indonesia with a high proportion of home deliveries, a low attendance of four antenatal services and a low postnatal care uptake. This paper aims to explore community members' perspectives on antenatal and postnatal care services, including reasons for using or not using these services, the services received during antenatal and postnatal care, and cultural practices during antenatal and postnatal periods in Garut, Sukabumi and Ciamis districts of West Java province. A qualitative study was conducted from March to July 2009 in six villages in three districts of West Java province. Twenty focus group discussions (FGDs) and 165 in-depth interviews were carried out involving a total of 295 respondents. The guidelines for FGDs and in-depth interviews included the topics of community experiences with antenatal and postnatal care services, reasons for not attending the services, and cultural practices during antenatal and postnatal periods. Our study found that the main reason women attended antenatal and postnatal care services was to ensure the safe health of both mother and infant. Financial difficulty emerged as the major issue among women who did not fulfil the minimum requirements of four antenatal care services or two postnatal care services within the first month after delivery. This was related to the cost of health services, transportation costs, or both. In remote areas, the limited availability of health services was also a problem, especially if the village midwife frequently travelled out of the village. The distances from health facilities, in addition to poor road conditions were major concerns, particularly for those living in remote areas.

    Flying foxes have been considered to be involved in the transmission of serious infectious diseases to humans. Using questionnaires, we aimed to determine the direct and/or indirect contacts of flying foxes in an Indonesian nature conservation area with domestic animals and humans living in the surrounding area. We surveyed 150 residents of 10 villages in West Java. Villages were classified into 3 groups: inside and/or within 1 km from the outer border of the conservation area and 1-5 km or 5-10 km away from the reserve's outer border. Data were collected by direct interview using a structured questionnaire consisting of the respondent characteristics (age, sex and occupation); histories of contacts between flying foxes and humans, dogs and other domestic animals; and knowledge about infectious diseases, mainly rabies, in flying foxes. We found that flying foxes from the nature conservation area often enter residential areas at night to look for food, especially during the fruit season. In these residential areas, flying foxes had direct contacts with humans and a few contacts with domestic animals, especially dogs. People who encounter flying foxes seldom used personal protective equipment, such as leather gloves, goggles and caps. The residents living around the conservation area mostly had poor knowledge about flying foxes and disease transmission. This situation shows that the population in this region is at a quite high risk for contracting infectious diseases from flying foxes.

    Ciloto is one of the most prone landslide hazard areas in Indonesia. Several landslides in 2012 and 2013 had been recorded in Ciloto and damaged infrastructure around the area. Investigating the history of ground movement along slope area before the landslide happened could support the hazard mitigation in the future. Considering to an efficient surveying method, space-borne SAR processing is the one appropriate way to monitor the phenomenon in past years. The purpose of this study is detecting ground movement using multi-temporal synthetic aperture radar images. We use 13 ALOS PALSAR images from 2007 to 2009 with combination Fine Beam Single (FBS) and Fine Beam Double (FBD) polarization to investigate the slow movement on slope topography. MAI (Multiple Aperture Interferometry) InSAR method is used to analyze the ground movement from both line-of-sight and along-track direction. We split the synthetic aperture into two-looking aperture so that along-track displacement could be created by the difference of forward-backward looking interferograms. With integration of both methods, we could more precisely detect the movement in prone landslide area and achieve two measurements produced by the same interferogram. However, InSAR requires smaller baseline and good temporal baseline between master and slave images to avoid decorellation. There are only several pairs that meet the condition of proper length and temporal baseline indeed the location is also on the agriculture area where is mostly covered by vegetation. The result for two years observation shows that there is insignificant slow movement along slope surface in Ciloto with -2 - -7 cm in range looks or line of sight and 9-40 cm in along track direction. Based on geometry SAR , the most visible detecting of displacement is on the north-west area due to utilization of ascending SAR images.

To achieve this target, Government puts energy sector as one of the top priorities since it is the second strongest contributor to national GHG emissions. The main purpose of this paper is to apply the method of fugitive emissions calculation to the existing natural gas pipeline in Indonesia. Fugitive emissions are the major component of GHG emissions from natural gas systems and methane (CH4, the primary component of natural gas pipeline, is a potent GHG. Tiered approaches from Interstate Natural Gas Association of America (INGAA are implemented in this paper as the estimation guidelines. A case study of a natural gas pipeline system in Indonesia is analyzed to compare the GHG emissions level resulted from Tier 1 and Tier 2 methods. In these methods, the input data are pipeline length, the number of compressor stations, and the number of meter and pressure regulation stations. In this case, the GHG emissions level of Tier 2 is significantly different from Tier 1. The variation of pipeline length shows that for the length under 479.2 miles, Tier 1 gives lower amount of CO2 equivalent than Tier 2. The differences of these estimation methods and results can be furtherly developed to provide relevant information and recommendation for the Companies and Government to record the emissions level from natural gas transmission pipeline according to their needs and purposes.

    Indonesia has great number of geothermal potential separated by two kind of potential, 16.13 GW for high enthalpy and 7.88 GW for low enthalpy speculative resources [4]. In the end of 2013, Ministry of Energy and Mineral Resources stated that Geothermal Power Plant (GPP) in Indonesia have been built about 1.34 GW in capacity and wanted to seriously develop geothermal potential up to 6.64 GW by 2025 [8]. Cost is one of famous obstacle in Indonesia's GPP Development. To reduce grand total cost of GPP, this paper will present the relation between thermodynamic and economic analysis in purpose to find the most economical gas removal system in GPP. By gleaning data at Kamojang Steam Field on behalf of PT Pertamina Geothermal Energy, this study will thermodynamically analyze and calculate a GPP preliminary design with software, named as Cycle Tempo 5.0. In additional, writers create motive steam calculator (based on C++ language) to enhance thermodynamic analysis for gas removal system (GRS) and adapted the results in Cycle Tempo 5.0. After thermodynamic analysis has been done, economic study will be undertaken by Net Present Value Analysis to compare the utilization cost of three different GRS and find which kind of GRS is more economical for nearly 30 years operation. For the result, Dual LRVP has higher performance than the others, spend less utilization cost and more economical for nearly 30 years operation. Moreover, the economic analysis for replacement of gas removal system shown in this paper too. In conclusion, GPP with Dual LRVP is proper to be developed in the future Geothermal Power Plant or to replace the existing GRS in some existing GPP in Indonesia.

    Inadequate nutrient intake as part of a complementary feeding diet is attributable to poor feeding practices and poor access to nutritious foods. Household socio-economic situation (SES) has an influence on food expenditure and access to locally available, nutrient-dense foods and fortified foods. This study aimed to develop and compare complementary feeding recommendations (CFR) for 12-23-month-old children in different SES and evaluate the contribution of fortified foods in meeting nutrient requirements. A cross-sectional survey was conducted in low and medium SES households (n 114/group) in urban Bandung district, West Java province, Indonesia. Food pattern, portion size and affordability were assessed, and CFR were developed for the low SES (LSES) and middle SES (MSES) using a linear programming (LP) approach; two models - with and without fortified foods - were run using LP, and the contribution of fortified foods in the final CFR was identified. Milk products, fortified biscuits and manufactured infant cereals were the most locally available and consumed fortified foods in the market. With the inclusion of fortified foods, problem nutrients were thiamin in LSES and folate and thiamin in MSES groups. Without fortified foods, more problem nutrients were identified in LSES, that is, Ca, Fe, Zn, niacin and thiamin. As MSES consumed more fortified foods, removing fortified foods was not possible, because most of the micronutrient-dense foods were removed from their food basket. There were comparable nutrient adequacy and problem nutrients between LSES and MSES when fortified foods were included. Exclusion of fortified foods in LSES was associated with more problem nutrients in the complementary feeding diet.

During extensive field researches on the diversity and distribution of Selaginella in Java, between 2007 and 2014, an alien species has been found in nature, i.e. Selaginella uncinata. This species is a trailing herb with small, wiry, creeping main stem, fan-shaped branches, rooting at the nodes to c.a. 100 cm long or more; leaves are dimorphic, 4-ranked, and characterized by conspicuous blue iridescent; strobili are tetragonal, up to c.a. 2 cm long. S. uncinata was found growing wild in the highlands with high rainfall, namely: Cibodas Botanical Garden, Cianjur, West Java and Tawangsari, in the city district of Wonosobo, Central Java, Indonesia. Transplant experiments showed that this plant was able to grow and reproduce well in lowlands (Depok, 107 m asl. and highlands (Wonosobo, 768 m asl.. In the experimental garden, it could compete successfully with native species of Javan selaginellas, for space, sunlight and nutrients. Therefore, we must be concerned about the invasion ability of this species.

    Indonesia is the source of raw essential oil in the world. Essential oils are used in various types of industries such as food and beverage, flavour, fragrance, perfumery, pharmaceuticals, and cosmetics. However, the development of Indonesian essential oil industry has not been encouraging for the production of essential oils, further it is unable to meet global demand. Besides that, the quality of volatile oil resulted cannot meet the international market standards. Based on the facts, the potential of Indonesian essential oils needs to be developed to provide added value, through increased production, improved quality and product diversification. One part of Indonesia having abundant of raw essential oil source is Central Java. Central Java has the quite large potential production of essential oils. Some essential oils produced from refining industry owned by the government, private and community sectors include cananga oils (Boyolali district), clove oils (Semarang district), patchouli oils (Brebes district, Pemalang district, and Klaten district). The main problem in the development of plants industries that producing essential oil in Central Java is low crops production, farming properties, quality of essential oils are diverse, providing poor-quality products and volatile oil price fluctuations. Marketing constraints of Central Java essential oils are quite complex supply chain. In general, marketing constraints of essential oils due to three factors, namely the low quality due to type of essential oil business that generally shaped small businesses with different capital and technology, domestic marketing is still a buyer-market (price determined by the buyer) because of weak bargaining position processors businessman, and prices fluctuate (domestic and foreign) due to uncontrolled domestic production and inter-country competition among manufacturers.

    Indonesia has a high vulnerability towards earthquakes. The low adaptive capacity could make the earthquake become disaster that should be concerned. That is why risk management should be applied to reduce the impacts, such as estimating the economic loss caused by hazard. The study area of this research is West Java. The main reason of West Java being vulnerable toward earthquake is the existence of active faults. These active faults are Lembang Fault, Cimandiri Fault, Baribis Fault, and also Megathrust subduction zone. This research tries to estimates the value of earthquakes economic loss from some sources in West Java. The economic loss is calculated by using HAZUS method. The components that should be known are hazard (earthquakes), exposure (building), and the vulnerability. Spatial modeling is aimed to build the exposure data and make user get the information easier by showing the distribution map, not only in tabular data. As the result, West Java could have economic loss up to 1,925,122,301,868,140 IDR ± 364,683,058,851,703.00 IDR, which is estimated from six earthquake sources with maximum possibly magnitude. However, the estimation of economic loss value in this research is the worst case earthquakes occurrence which is probably over-estimated.

    We sought to elucidate the role of migratory birds in transmission of H5N1 in an enzoonotic area. Resident, captive, and migratory birds were sampled at five sites in Java, Indonesia. Mist nets were used to trap birds. Birds were identified to species. RNA was extracted from swabs and reverse transcriptase polymerase chain reaction (RT-PCR) conducted for the HA and M genes of H5N1. Antibodies were detected by enzyme-linked immunosorbent assay and hemagglutination inhibition test. Between October 2006 and September 2007, a total of 4,067 captive, resident, and migratory birds comprising 98 species in 23 genera were sampled. The most commonly collected birds were the common sandpiper (6% of total), striated heron (3%), and the domestic chicken (14%). The overall prevalence of H5N1 antibodies was 5.3%. A significantly higher percentage of captive birds (16.1%) showed antibody evidence of H5N1 exposure when compared to migratory or resident birds. The greatest number of seropositive birds in each category were Muschovy duck (captive), striated heron (resident), and the Pacific golden plover (migratory). Seven apparently well captive birds yielded molecular evidence of H5N1 infection. Following amplification, the HA, NA, and M genes were analyzed. Phylogenetic analysis of the HA gene showed that the isolates were 97% similar to EU124153.1 A/chicken/West Java/Garut May 2006, an isolate obtained in a similar region of West Java. While no known markers of neuraminidase inhibitor resistance were found within the NA gene, M segment analysis revealed the V27A mutation known to confer resistance to adamantanes. Our results demonstrate moderate serologic evidence of H5N1 infection in captive birds, sampled in five sites in Java, Indonesia, but only occasional infection in resident and migratory birds. These data imply that in an enzoonotic region of Indonesia the role of migratory birds in transmission of H5N1 is limited.

    This research note aims to understand the impact of parental migration on the children who stay behind by examining the issue of smoking. It asks whether tobacco use and exposure are higher among children in migrant households compared with those in non-migrant households in Java, Indonesia. Data were collected in 2008 in two provinces, West Java and East Java, as part of the Child Health and Migrant Parents in South-East Asia (CHAMPSEA) Project. The analytical sample used here relates to children aged 9, 10 and 11 living in both non-migrant and transnational households (N=451). The findings show that the incidence of ever having smoked among these primary school-aged children is relatively low at less than 10 percent, but that boys are much more likely to have used tobacco than girls. Findings from multivariate logistic models predicting smoking behavior show no difference between the children of migrants and non-migrants; nor does household wealth appear to influence whether or not a child has tried tobacco. Gender, child stunting (low height-for-age), carer's education, family functioning and tobacco use by friends are the four main factors found to be significantly associated with child smoking.

    Diatoms are popular name for Bacillariophyte, the microalgae with the specific characteristic of silicious cell walls that well preserved in the sediments. The different diatoms assemblage in the sediment layers indicate different environment at the time of the diatoms live and deposited. Telaga Warna is small lake in Dieng Plateau. Telaga means lake, Warna means colour. It is called Telaga Warna because previously have 4 colours i.e. red, white, blue, and yellow which was influenced by weather, time, and site of view. This study aims to analysis the diatoms communities and water quality of Telaga Warna Dieng, Java, Indonesia. Coring conducted at three different locations. Water sampling carried out on all three spots. Analysis of diatoms consist of three stages: digestion, preparation, and identification of diatoms. There were 59 diatoms species found in Telaga Warna Dieng that were belong to 9 groups diatoms of centric, arafid, eunotoid, birafid, monorafid, birafid, epitemid, nitzschioid, and surirelloid. Eunotia, Pinnularia, and Melosira were the dominant genus from Telaga Warna. The water quality parameters that exceeded Indonesia Water Quality Standard were pH (2.2 – 5.4), Pb, Cd, Cr, Cu. Based on the abundance of species Eunotia and Pinnularia in Telaga Warna Dieng indicates that water tends to be acidic. The dominance of Melosira indicates waters rich in nitrogen. Based on the total concentration of nitrogen and phosphorous, Telaga Warna was in an eutrophic – hipereutrophic conditions with total nitrogen concentration > 1.9 mg/L and total phosphorus concentration > 0.1 mg/L.

    Japanese encephalitis virus (JEV) is a fatal disease in Asia. Pigs are considered to be the effective amplifying host for JEV in the peridomestic environment. Bali Island and Java Island in Indonesia provide a model to assess the effect of pigs on JEV transmission, since the pig density is nearly 100-fold higher in Bali than Java, while the geographic and climatologic environments are equivalent in these areas. We surveyed antibodies to JEV among 123 pigs in Mengwi (Bali) and 96 pigs in Tulungagung (East Java) in 2008 by the hemagglutination-inhibition (HAI) test. Overall prevalences were 49% in Bali and 6% in Java, with a significant difference between them (P Java. In addition, 2-mercaptoethanol-sensitive antibodies were found only from Bali samples. Further, the average HAI antibody titer obtained from positive samples was significantly higher in Bali (1:52) than Java (1:10; P Java.

    This paper presents δ11B data for hot springs, hot acid crater lakes, geothermal brines and a steam vent from Java, Indonesia. The processes that produce a large range of the δ11B values were investigated, including the possible input of seawater as well as the contrast δ11B compositions of acid sulfate and acid chloride crater lakes. The δ11B values of hot springs ranged from - 2.4 to + 28.7‰ and acid crater lakes ranged from + 0.6 to + 34.9‰. The δ11B and Cl/B values in waters from the Parangtritis and Krakal geothermal systems confirmed seawater input. The δ11B values of acid sulfate crater lakes ranged from + 5.5 to + 34.9‰ and were higher than the δ11B of + 0.6‰ of the acid chloride crater lake. The heavier δ11B in the acid sulfate crater lakes was caused by a combination of vapor phase addition and further enrichment due to evaporation and B adsorption onto clay minerals. In contrast, the light δ11B of the acid chloride crater lake was a result of acid water-rocks interaction. The correlations of δ11B composition with δ18O and δ2H indicated that the B isotope corresponded to their groundwater mixing sources, but not for J21 (Segaran) and J48 (Cikundul) that underwent 11B isotope enrichment by B adsorption into minerals.

    Surabaya river is one of urban rivers in East Java Province, Indonesia that is a part of Brantas river that flows in four urban and industrial cities of Mojokerto, Gresik, Sidoarjo, and Surabaya. The urban populations and industries along the river pose serious threat to the river mainly for their anthropogenic pollutants. This study aims to characterize the magnetic properties of sediments in various locations along Surabaya river and correlate these magnetic properties to the level of pollution along the river. Samples are taken and measured through a series of magnetic measurements. The mass-specific magnetic susceptibility of sediments ranges from 259.4 to 1134.8 × 10-8 m3kg-1. The magnetic minerals are predominantly PSD to MD magnetite with the grain size range from 6 to 14 μm. The mass-specific magnetic susceptibility tends to decreases downstream as accumulation of magnetic minerals in sediments is affected not only by the amount of household and industrial wastes but also by sediment dredging, construction of embankments, and extensive erosion arround the river. Sediments located in the industrial zone on the upstream area tend to have higher mass-specific magnetic susceptibility than in the non-industrial zones on the downstream area.

    More than one-quarter of under-five children in the developing world are stunted, and those with poor nutrient intake are at risk of irreversible cognitive impairment. The purpose of this study was to determine the relationship between dietary diversity and child stunting in an Indonesian context. Dietary diversity was assessed using a maternal-reported checklist of 12 food groups, summed as a Household Dietary Diversity Score. Stunting was defined as Java, Indonesia. Logistic regression models were constructed to test the association between dietary diversity and child stunting. The prevalence of child stunting was 39.4%, and the percentage of households consuming food groups high in protein and calcium, like dairy products (41%), and meat/poultry, (65%) was lower compared with other food groups. The unadjusted model revealed that higher dietary diversity scores were associated with lower likelihood of child stunting (OR=0.89; 95% CI=0.80-0.98). This relationship remained significant after adjustment for family size, maternal literacy, food expenditure, breastfeeding, energy, and protein intake (OR=0.89; 95% CI=0.80-0.99). The dietary diversity score was moderate, with consumption of dairy products and meat/poultry lowest among 12 food groups. Hence, population interventions should focus on promoting food groups currently lacking in maternal and child diet, including those rich in growth-promoting nutrients like dairy, meat/poultry. These results, from an Indonesian context, confirm the widely observed protective relationship between dietary diversity and child stunting.

  1. Halimeda bioherms of the eastern Java Sea, Indonesia

    Extensive areas of coalescing bioherms composed primarily of disarticulated Halimeda plates occur on a large carbonate bank (Kalukalukuang Bank) located 50 to 70 km east of the central Sunda Shelf margin (eastern Java Sea, Indonesia). High-resolution seismic profiles suggest that these features attain maximum thicknesses of up to 52 m above an acoustically reflective surface interpreted as the top of the Pleistocene. Piston cores and vibracores from the bioherms indicate a composition of Halimeda packstone containing varying amounts of foraminifera-rich carbonate mud. A shell lag occurs at their base above the Pleistocene(?) surface. Seismic stratigraphy of the bioherms suggests that they generally developed as individual mounds that accreted both vertically and laterally until they coalesced to form composite features. Discordant reflectors are common and probably represent morphological modifications associated with high-energy events, current scour, or local mass movement. Halimeda bioherms occur in water depths ≥20 m on both exposed and reef-protected bank margins, unlike the only other recorded modern examples, which occur in the lagoonal facies behind the northern Great Barrier ribbon reefs of Australia. Their presence and rapid growth rates (to 5.9 m/1000 yr as determined from carbon-14 dating of piston core subsamples) are possibly related to upwelling of deep, nutrient-rich, south-moving water from Makassar Strait.

    Full Text Available The importance of medicinal plants for the preparation of “jamu" has been recognized in Indonesia and especially Java since ancient times. Jamu usually consists of blends of several kinds of plants or other natural materials. Jamu remains popular and there is an increasing demand for jamu in such diverse fields as health and beauty care, medical treatment and the preparation of fresh beverages. The problems result from the fact of most materials needed for preparation of jamu being natural resources. These materials are collected by the people in the forest and sold to the producers without thought for the conservation of these plants in nature with the consequence that some of the medicinal plants concerned have become difficult to find in the wild. Studies in the field in West, Central and East Java and at jamu enterprises and raw material sales centre show that several species of jamu raw material are very scarce. They should be classified as endangered. In this paper the significance of the endangered species as jamu in traditional Indonesian medicine is assessed and a strategy for conserving them "in situ and ex situ " is discussed.

The cinder cones occur singly or in small groups, with diameter of the base ranges from 130 - 750 m and the height is around 250 m. Within the volcanic field, the cinder cones are spread over the volcanic area at the distance of 4 to 14 km from the eruption center of the Slamet Volcano. They are concentrated within latitudes 7°11’00” - 7°16’00” S,, and longitudes 109°15’00” - 109°18’00” E. The density of the cinder cones is about 1.5 cones/km2. Most of the cinder cones lie on the Tertiary sedimentary rocks along the NW-trending fault system and on radial fractures. The structural pattern may be related to the radial faults in this region. The cone surfaces are commonly blanketed by Slamet air-falls and lava flows. The deposits consist of poorly bedded, very coarse-grained, occasionally overlain by oxidized scoria, and large-sized of ballistic bombs and blocks. There are various kind of volcanic bombs originating from scoriae ballistic rock fragments. The other kind of volcanic bombs are breadcrust bomb, almond seed or contorted shape. All of the cinder cones have undergone degradation, which can be observed from the characters of gully density and surface morphology. By using Porter parameters, Hco is equal to 0.25 Wco, whilst Wcr is equal to 0.40 Wco. The Hco/Wco ratio is higher than Hco = 0.2 Wco reference line.

    Merapi is an almost persistently active basalt to basaltic andesite volcanic complex in Central Java (Indonesia) and often referred to as the type volcano for small-volume pyroclastic flows generated by gravitational lava dome failures (Merapi-type nuées ardentes). Stratigraphic field data, published and new radiocarbon ages in conjunction with a new set of 40K-40Ar and 40Ar-39Ar ages, and whole-rock geochemical data allow a reassessment of the geological and geochemical evolution of the volcanic complex. An adapted version of the published geological map of Merapi [(Wirakusumah et al. 1989), Peta Geologi Gunungapi Merapi, Jawa Tengah (Geologic map of Merapi volcano, Central Java), 1:50,000] is presented, in which eight main volcano stratigraphic units are distinguished, linked to three main evolutionary stages of the volcanic complex—Proto-Merapi, Old Merapi and New Merapi. Construction of the Merapi volcanic complex began after 170 ka. The two earliest (Proto-Merapi) volcanic edifices, Gunung Bibi (109 ± 60 ka), a small basaltic andesite volcanic structure on Merapi's north-east flank, and Gunung Turgo and Gunung Plawangan (138 ± 3 ka; 135 ± 3 ka), two basaltic hills in the southern sector of the volcano, predate the Merapi cone sensu stricto. Old Merapi started to grow at ~30 ka, building a stratovolcano of basaltic andesite lavas and intercalated pyroclastic rocks. This older Merapi edifice was destroyed by one or, possibly, several flank failures, the latest of which occurred after 4.8 ± 1.5 ka and marks the end of the Old Merapi stage. The construction of the recent Merapi cone (New Merapi) began afterwards. Mostly basaltic andesite pyroclastic and epiclastic deposits of both Old and New Merapi (<11,792 ± 90 14C years BP) cover the lower flanks of the edifice. A shift from medium-K to high-K character of the eruptive products occurred at ~1,900 14C years BP, with all younger products having high-K affinity. The radiocarbon record points towards an

The moisture content (m.c., intactness of kernels, and the percentages of groundnut kernels infected by each species of fungi were analyzed. In genera, the m.c. of the samples collected during the dry season was lower than of those collected during the wet season. Also, the m.c. of samples collected from FHG, FSS and MW was higher than of those collected from WS and RS. The m.c. of samples collected from FHG was the highest (12.5-45.75%, but the percentages of damaged kernels were the lowest (2.5-13.8%, because the samples were shelled manually. A total of 25 species of fungi were isolated from samples collected from the 4 localities. They were Acremonium strictum, Aspergillus candidus, A. flavus, A. niger, A. ochraceus, A. tamarii, A. wentii, Botryodiplodia theobromae, Cladosporium cladosporioides, C. sphaerospermum, Eumtium chevalieri, E. repens, E. rubrum, Fusarium equiseti, F. longipes, F. oxysporum, F. semitectum, Mucor sp., Papulaspora sp., Pestalotia sp., Penicillium aethiopicum, P. citrinum, Rhizapus sp., R. stolonifer and Syncephalastrum sp.

    Sangiran (Solo Basin, Central Java, Indonesia) is the singular Homo erectus fossil locale for Early Pleistocene Southeast Asia. Sangiran is the source for more than 80 specimens in deposits with (40)Ar/(39)Ar ages of 1.51-0.9 Ma. In April 2001, we recovered a H. erectus left maxilla fragment (preserving P(3)- M(2)) from the Sangiran site of Bapang. The find spot lies at the base of the Bapang Formation type section in cemented gravelly sands traditionally called the Grenzbank Zone. Two meters above the find spot, pumice hornblende has produced an (40)Ar/(39)Ar age of 1.51 ± 0.08 Ma. With the addition of Bpg 2001.04, Sangiran now has five H. erectus maxillae. We compare the new maxilla with homologs representing Sangiran H. erectus, Zhoukoudian H. erectus, Western H. erectus (pooled African and Georgian specimens), and Homo habilis. Greatest contrast is with the Zhoukoudian maxillae, which appear to exhibit a derived pattern of premolar-molar relationships compared to Western and Sangiran H. erectus. The dental patterns suggest distinct demic origins for the earlier H. erectus populations represented at Sangiran and the later population represented at Zhoukoudian. These two east Asian populations, separated by 5000 km and nearly 800 k.yr., may have had separate origins from different African/west Eurasian populations.

    The estuarine ecosystem is known as suitable breeding sites for fishes because this particular habitat is receiving continuous organic matters from river ways and constant sunlight due to its depth that allows sunlight penetration. Cimandiri estuary is one of the estuaries located in the south of Java Island close to the Indian Ocean and known as a suitable habitat for eel larva that routinely collected by local people. Eel habitat has a relationship with the dynamic of space. This dynamic influenced by season, water flow, tide, bathymetry, salinity and dissolved oxygen (DO). The geographic information system is an approach in studying habitat dynamic, through modeling. Furthermore, the spatial model for eel larva habitat is required for land use planning that aimed to achieve sustainable eels larva rearing and conserve estuarine habitat as well. The aim of this research was to investigate dynamics on spatial habitat of eel larva at Cimandiri estuary, West Java.

    Sustainable water resources management is essential since it ensures the integration of social, economical and environmental issues into all stages of water resources management. The development and application of water sustainability indices to achieve sustainable water management has been successfully done in the last few years. Although existing water sustainability indices have successfully provided information on current conditions of water resources and prioritised water related issues, they have been developed for specific case study areas. This study therefore aims at developing a water sustainability index for West Java, Indonesia. The overall steps for developing the index include developing a conceptual framework, application of Delphi technique to finalise the components/indicators of the index, applying the index to case studies and robustness analysis of the index. This paper, which is the first in a two-part series, discusses the first step, namely developing the conceptual framework of the West Java Water Sustainability Index (WJWSI). It outlines the criteria for identifying the initial set of components/indicators and based on those criteria, a detailed justification for selecting each component and indicator is also presented. The second paper of the series presents the application of Delphi technique to finalise the framework of WJWSI based on feedback from selected stakeholders. The remaining steps of developing WJWSI will be undertaken in the future.

    The Lembang fault is located around eight kilometers from Bandung City, West Java, Indonesia. The existence of this fault runs through densely populated settlement and tourism area. It is an active fault structure with increasing seismic activity where the 28 August 2011 earthquake occurred. The seismic response at the site is strongly influenced by local geological conditions. The ambient noise measurements from the western part of this fault give strong implication for a complex 3-D tectonic setting. Hence, near surface Electromagnetic (EM) measurements are carried out to understand the location of the local active fault of the research area. Hence, near surface EM measurements are carried out to understand the location of the local active fault and the top of the basement structure of the research area. The Transientelectromagnetic (TEM) measurements are carried out along three profiles, which include 35 TEM soundings. The results indicate that TEM data give detailed conductivity distribution of fault structure in the study area.

It is an active fault structure with increasing seismic activity where the 28 August 2011 earthquake occurred. The seismic response at the site is strongly influenced by local geological conditions. The ambient noise measurements from the western part of this fault give strong implication for a complex 3-D tectonic setting. Hence, near surface Electromagnetic (EM) measurements are carried out to understand the location of the local active fault of the research area. Hence, near surface EM measurements are carried out to understand the location of the local active fault and the top of the basement structure of the research area. The Transientelectromagnetic (TEM) measurements are carried out along three profiles, which include 35 TEM soundings. The results indicate that TEM data give detailed conductivity distribution of fault structure in the study area.

    Full Text Available Indonesia consistently experiences dry climatic conditions and droughts during El Niño, with significant consequences for rice production. To mitigate the impacts of such droughts, robust, simple and timely rainfall forecast is critically important for predicting drought prior to planting time over rice growing areas in Indonesia. The main objective of this study was to predict drought in rice growing areas using ensemble seasonal prediction. The skill of National Oceanic and Atmospheric Administration’s (NOAA’s seasonal prediction model Climate Forecast System version 2 (CFSv2 for predicting rice drought in West Java was investigated in a series of hindcast experiments in 1989-2010. The Constructed Analogue (CA method was employed to produce downscaled local rainfall prediction with stream function (y and velocity potential (c at 850 hPa as predictors and observed rainfall as predictant. We used forty two rain gauges in northern part of West Java in Indramayu, Cirebon, Sumedang and Majalengka Districts. To be able to quantify the uncertainties, a multi-window scheme for predictors was applied to obtain ensemble rainfall prediction. Drought events in dry season planting were predicted by rainfall thresholds. The skill of downscaled rainfall prediction was assessed using Relative Operating Characteristics (ROC method. Results of the study showed that the skills of the probabilistic seasonal prediction for early detection of rice area drought were found to range from 62% to 82% with an improved lead time of 2-4 months. The lead time of 2-4 months provided sufficient time for practical policy makers, extension workers and farmers to cope with drought by preparing suitable farming practices and equipments.

    The low and unstable yields of rainfed lowland rice in Central Java can be attributed to drought, nutrient stress, pest infestation or a combination of these factors. Field experiments were conducted in six crop seasons from 1997 to 2000 at Jakenan Experiment Station to quantify the yield loss due t

    New Pb isotope data are presented for Gede Volcanic Complex, Salak and Galunggung volcanoes in West Java, Merbabu and Merapi volcanoes in Central Java and Ijen Volcanic Complex in East Java of the Sunda arc, Indonesia. New O isotope data for Merbabu and new geochemical and radiogenic isotope data (Sr-Nd-Hf-Pb) for three West Javanese, upper crustal, Tertiary sedimentary rocks are also presented. The data are combined with published geochemical and isotopic data to constrain the relative importance of crustal assimilation and subducted input of crustal material in petrogenesis in Java. Also discussed are the significance of limestone assimilation in controlling the geochemical and isotopic characteristics of erupted Javanese rocks and the geochemical impact upon central and eastern Javanese arc rocks due to the subduction of Roo Rise between 105 and 109°E. The negative correlation between Pb isotopes and SiO2, combined with mantle-like δ18O values in Gede Volcanic Complex rocks, West Java, are most likely explained by assimilation of more isotopically-primitive arc rocks and/or ophiolitic crust known to outcrop in West Java. The negative Pb isotope-SiO2 trend cannot be explained by assimilation of the known compositions of the upper crustal rocks. A peak in δ18O whole-rock and mineral values in Central Javanese volcanic rocks (Merbabu and Merapi) combined with along-arc trends in Sr isotope ratios suggest that a different or additional crustal assimilant exerts control on the isotopic composition of Central Javanese volcanic rocks. This assimilant (likely carbonate material) is characterised by high δ18O and high Sr isotope ratio but is not particularly elevated in its Pb isotopic ratio. Once the effects of crustal assimilation are accounted for, strong East to West Java regional variations in Ba concentration, Ba/Hf ratio and Pb isotopic composition are evident. These differences are attributed to heterogeneity in the subducted source input component along the

    Universal childhood hepatitis B vaccination was introduced in Indonesia in 1997; by 2008, coverage was estimated to be 78%. This study aimed to investigate the serologic status and virologic characteristics of hepatitis B virus (HBV) among the children in East Java. A total of 229 healthy children born during 1994-1999 were enrolled in this study. Overall, 3.1% were positive for hepatitis B surface antigen (HBsAg) and 23.6% were positive for antibody to HBsAg (anti-HBs). HBV DNA was detected in 5 of 222 HBsAg-negative carriers, which were suggested to be cases of occult HBV infection. A single amino substitution (T126I) in the S region was frequently found. HBV infection remains endemic, and the prevalence of anti-HBs remains insufficient among children in East Java, Indonesia.

    The aim of this paper is to discuss the characteristics of recorded seismic noise in central Java by using empirical interstation Green's function (EGF). We have utilized the data from the MERAMEX project (May - October 2004) to determine the EGF within the study area. We have calculated 6893 cross correlations based Green's function of vertical-vertical components. In order to study both primary and secondary microseisms, we measured azimuthal dependence of signal-to-noise ratio (SNR) of Green's function at a period range from 3 to 25 s (or 0.04 - 0.33 Hz). In general, the cross-correlation functions (CCF) of positive and negative axes are not symmetric, which indicate that the dominant source locations are not evenly distributed. Based on period-azimuth maps of SNR the relatively higher SNRs are appeared in the period from 3 to 12 s (0.08 - 0.33 Hz), which can be related to the secondary microseisms. Our result also indicates that the most energetic seismic noise source came from or was generated in the northeastern part or northern part of the study region with range of azimuth form 290° to 360° and from 0° to 25°, which is related to the coupling of the northern coast of central Java and the ocean current of the Java sea.

    East Nusa Tenggara (NTT) and Central Java Provinces, Indonesia. To estimate the average annual risk of tuberculous infection (ARTI) among school children aged 6-9 years in each province. Children attending Classes 1-4 in 65 schools in NTT and 79 in Central Java, selected by two-stage sampling, were intradermally administered 2 tuberculin units of purified protein derivative RT23 with Tween 80 on the mid-volar aspect of the left forearm. The maximum transverse diameter of induration was measured 72 h later. The analysis was carried out among 5479 satisfactorily test-read children in NTT and 6943 in Central Java. One hundred and fifty-five new sputum smear-positive pulmonary tuberculosis (PTB) cases (78 in NTT and 77 in Central Java) were also tuberculin tested. Based on the frequency distribution of reaction sizes among the children and PTB cases, the prevalence of infection was estimated by the mirror-image method using the modes of tuberculous reactions at 15 and 17 mm. Using the 15 mm mode, ARTI was estimated at 1% in NTT and 0.9% in Central Java. Using the 17 mm mode, ARTI was estimated at 0.5% in NTT and 0.4% in Central Java. Transmission of tuberculous infection may be further reduced by intensification of tuberculosis control efforts.

    We study the local seismicity around the spectacular Lusi eruption site, a sedimentary- hosted hydrothermal system in East Java. Lusi is located 10 km NE of the Arjuno-Welirang volcanic complex and is fed by both mantellic and hydrothermal fluids rising and mixing with those present in the sedimentary formations. During a period of 17 months, we observed 289 micro-seismic earthquakes with local magnitudes ranging from ML0.5 to ML1.7. The events predominantly nucleate at depths of 8-13 km below the Arjuno-Welirang volcanic complex. Despite the geological evidence of active tectonic deformation and faulting observed at the surface, little to no seismicity is observed in the sedimentary basin hosting Lusi. Although we cannot entirely rule out artifacts due to a significantly increased detection threshold in the sedimentary basin, the deficit in seismicity suggests aseismic deformation beneath Lusi due to the large amount of fluids that may lubricate the fault system. An analysis of focal mechanisms of seven selected events around the Arjuno-Welirang volcanic complex indicate predominantly strike-slip faulting activity in the region SW of Lusi. This type of activity is consistent the orientation and the movements observed for the Watukosek fault system that extends from the volcanic complex towards the NE of Java. Our results suggest that the tectonic deformation of the region is characterized by scattered faulting, rather than localized along a distinct fault plane.

    Paddy field is an important agricultural land in Indonesia, as one of the largest rice producing-country in the world. At least 26 from 33 provinces in Indonesia are characterized by the existence of paddy field landscape. However, due to the increasing of population and development of infrastructure building, a conversion of paddy field rapidly occurs in many sites. This study aimed to examine the dynamics change in paddy field in Karawang District-West Java during the period of 1994-2015. The method used in this study mainly by the remote sensing technique using satellite images data. The result indicated that conversion of paddy fields to built area/infrastructure in Karawang is approximately 10.326,6 ha. It took up 56% from the paddy that were changed. Based on the result, the changes are likely to occur in the middle of karawang district, near the central city. This result showed the change of paddy field in 1994 converted into some built-up areas such as settlement or roads in 2015. However, about 85.597,56 ha paddy field is not changed during these period. The study showed that paddy fields landscape is facing a changes over the last two decades.

    Tropical marine molluscs are traded globally. Larger species with slow life histories are under threat from over-exploitation. We report on the trade in protected marine mollusc shells in and from Java and Bali, Indonesia. Since 1987 twelve species of marine molluscs are protected under Indonesian law to shield them from overexploitation. Despite this protection they are traded openly in large volumes. We collected data on species composition, origins, volumes and prices at two large open markets (2013), collected data from wholesale traders (2013), and compiled seizure data by the Indonesian authorities (2008-2013). All twelve protected species were observed in trade. Smaller species were traded for Java and Bali, but the trade involves networks stretching hundreds of kilometres throughout Indonesia. Wholesale traders offer protected marine mollusc shells for the export market by the container or by the metric ton. Data from 20 confiscated shipments show an on-going trade in these molluscs. Over 42,000 shells were seized over a 5-year period, with a retail value of USD700,000 within Indonesia; horned helmet (Cassis cornuta) (>32,000 shells valued at USD500,000), chambered nautilus (Nautilus pompilius) (>3,000 shells, USD60,000) and giant clams (Tridacna spp.) (>2,000 shells, USD45,000) were traded in largest volumes. Two-thirds of this trade was destined for international markets, including in the USA and Asia-Pacific region. We demonstrated that the trade in protected marine mollusc shells in Indonesia is not controlled nor monitored, that it involves large volumes, and that networks of shell collectors, traders, middlemen and exporters span the globe. This impedes protection of these species on the ground and calls into question the effectiveness of protected species management in Indonesia; solutions are unlikely to be found only in Indonesia and must involve the cooperation of importing countries.

    Mature, synrift lacustrine shales of Eocene to Oligocene age and mature, late-rift coals and coaly shales of Oligocene to Miocene age are source rocks for oil and gas in two important petroleum systems of the onshore and offshore areas of the Northwest Java Basin. Biogenic gas and carbonate-sourced gas have also been identified. These hydrocarbons are trapped primarily in anticlines and fault blocks involving sandstone and carbonate reservoirs. These source rocks and reservoir rocks were deposited in a complex of Tertiary rift basins formed from single or multiple half-grabens on the south edge of the Sunda Shelf plate. The overall transgressive succession was punctuated by clastic input from the exposed Sunda Shelf and marine transgressions from the south. The Northwest Java province may contain more than 2 billion barrels of oil equivalent in addition to the 10 billion barrels of oil equivalent already identified.

    The eruption site in East Java nicknamed Lusi is an active sedimentary hosted hydrothermal system that has been active since the 29th of May 2006. The sedimentary sequences pierced by the Lusi feeder channel are brecciated and expelled at the surface as mud breccia mixed with boiling fluids. The depth of the conduit remains so far unknown as well as the age of some of the inferred stratigraphic sequences. Over the years we documented and collected a large set of erupted clast specimens since the initiation of the eruption. Here we describe the results of foraminifera and 87Sr/86Sr dating of selected scleractinian coral fragments and carbonate clasts rich in planktonic foraminifera collected around the eruption crater site. The clasts were collected in 2006 during the early eruptive phases of Lusi. The aim of this work is to constrain the age of the components and to improve the understanding of the, so far unknown, sequence of carbonate deposits inferred in this region of Java. Kujung and Tuban are the two formations consisting of carbonates known from this region. Based on planktonic foraminifera biostratigraphy, one group of the samples reveal to belong to the Planktonic Foraminifera Zone M5, with an age comprised between 16.29 and 15.10 Ma (Miocene, Latest Burdighalian to Langhian). The Sr isotope-based ages of clasts analysed for 87Sr/86Sr cover a larger time window spanning from Pliocene (Zanclean and Piacenzian), Miocene (Messinian) down to Oligocene (Chatian). The Pliocene and Messinian ages are unreasonably young from what is known of the local geology and one sample provided an 87Sr/86Sr age that is 8 My younger compared to that obtained from the planktonic foraminifera assemblage occurring in that sample. This suggests that this and the young samples have been contaminated by geological sediments with higher radiogenic Sr isotope composition. Therefore these samples may be ascribed to the Miocene Tuban Formation. The minimum age of 23.77 Ma obtained by 87

    Our previous study on MERAMEX data (Zulfakriza et al., 2014) obtained features of the tomographic images which correlate well with the surface geology of central Java in periods between 1 to 12 sec. Kendeng Basin and active volcanoes in the central part of this region are clearly imaged with low group velocities with values around 0.8 km/sec, while the carbonate structures in the southern part of the region correspond to higher group velocities in the range of 1.8 to 2.0 km/sec. In this current study, we invert dispersion curves obtained from seismic noise tomography to estimate shear wave-depth profiles of the region. The results are used to discuss the spatial variation of shear wave velocities for a depth range down from the surface to upper crust. Most of the shear wave velocity anomalies, including the upper crustal areas of the Kendeng basin and active volcanoes, are consistent with our previous study of Rayleigh wave group velocities and fit to the regional geology.

  15. Porous boundaries : Addressing calamities in East Java, Indonesia

    Directory of Open Access Journals (Sweden)

    Robert Wessing

    2010-04-01

    Full Text Available Social constructions of reality must account for adversity and calamities. In East Java this is commonly done with reference to the spirit world and to God, with only occasional appeals to modern science. Rather than being a uniform phenomenon, adversity can be conceptualized as happening on the individual, the household, the community, and the state levels. Explanations similarly vary from specific individual offences, to communal household or community culpability, and national-level disasters like tsunamis and volcanic eruptions that are blamed on the activities of gods and spirits. All these social units are seen as porous, and care must be taken to protect them from deleterious outside influences. Parallel to these explanations at all levels run appeals to God and His mercies. The difference between these streams of explanation is resolved in the case of the more pious by either denying the spirit world, or otherwise resolving them in various ways by unifying the categories of God and the spirit world.

    Full Text Available The benefit and transaction cost flow which people earn economically and socially from wild medicinal plant harvesting are addressed in this study. The objectives of this study are three aspects: defining how many users are involved in utilization of medicinal plant raw materials (MPRM, how users describing their perception and motivation and describing benefit and transaction cost which influence users to harvest the plants. Results showed that utilization of medicinal plants in Java is still widely used as commercial products then medical services. There are 41 stakeholders who involved in this study and the highest motivation and perception in production and industrial clusters are economic interest. But stakeholder's perception and motivation in traditional healthcare cluster is social interest. The different motivation and perception in both clusters causing stakeholder who are work in traditional healthcare lack of market information, but they are important if the government will improve the traditional medicine. Recommendation of this study is that medicinal plants need further research and product development which can help to expand the medicinal plant culture area in the natural forest. By this reason, government should develop good political will to increase the medicinal plant resources for public healthcare.

    Alien plants are invading protected areas worldwide, but there is little information from tropical Asia. Java has the longest record of human occupation in Asia and today supports 145 m people. Remnants of natural ecosystems survive in 12 small National Parks surrounded by dense human populations, making them highly vulnerable to invasions. We surveyed eight of these, along a rainfall gradient from lowland rainforest with >3000 mm annual rainfall to savanna with <1500 mm, and a 0-3158 m altitudinal gradient, using 403 10 × 5 m plots along trails. We found 67 invasive alien plant species, of which 33 occurred in only one park and two (Chromolaena odorata and Lantana camara) in all. Historical factors relating to plant introduction appeared to be as important as environmental factors in determining which species occurred in which park, while within parks canopy cover and altitude were generally most influential. Spread away from trails was only evident in open habitats, including natural savannas in Baluran National Park, threatened by invasion of Acacia nilotica. Existing control attempts for invasive aliens are reactive, localized, and intermittent, and insufficient resources are currently available for the early detection, prompt action, and continued monitoring that are needed.

    Fasciola gigantica and aspermic (hybrid) Fasciola flukes are thought to be distributed in Southeast Asian countries. The objectives of this study were to investigate the distribution of these flukes from unidentified ruminants in western Java, Indonesia, and to determine their distribution history into the area. Sixty Fasciola flukes from western Java were identified as F. gigantica based on the nucleotide sequences of the nuclear phosphoenolpyruvate carboxykinase (pepck) and DNA polymerase delta (pold) genes. The flukes were then analyzed phylogenetically based on the nucleotide sequence of the mitochondrial NADH dehydrogenase subunit 1 (nad1) gene, together with Fasciola flukes from other Asian countries. All but one F. gigantica fluke were classified in F. gigantica haplogroup C, which mainly contains nad1 haplotypes detected in flukes from Thailand, Vietnam, and China. A population genetic analysis suggested that haplogroup C spread from Thailand to the neighboring countries including Indonesia together with domestic ruminants, such as the swamp buffalo, Bubalus bubalis. The swamp buffalo is one of the important definitive hosts of Fasciola flukes in Indonesia, and is considered to have been domesticated in the north of Thailand. The remaining one fluke displayed a novel nad1 haplotype that has never been detected in the reference countries. Therefore, the origin of the fluke could not be established. No hybrid Fasciola flukes were detected in this study, in contrast to neighboring Asian countries. Copyright © 2016. Published by Elsevier Ireland Ltd.

    This paper presents the development of spectral hazard maps for Sumatra and Java islands, Indonesia and microzonation study for Jakarta city. The purpose of this study is to propose a revision of the seismic hazard map in Indonesian Seismic Code SNI 03-1726-2002. Some improvements in seismic hazard analysis were implemented in the analysis by considering the recent seismic activities around Java and Sumatra. The seismic hazard analysis was carried out using 3-dimension (3-D) seismic source models (fault source model) using the latest research works regarding the tectonic setting of Sumatra and Java. Two hazard levels were analysed for representing 10% and 2% probability of exceedance (PE) in 50 years ground motions for Sumatra and Java. Peak ground acceleration contour maps for those two hazard levels and two additional macrozonation maps for 10% PE in 50 years were produced during this research. These two additional maps represent short period (0.2 s) and long-period (1.0 s) spectra values at the bedrock. Microzonation study is performed in order to obtain ground motion parameters such as acceleration, amplification factor and response spectra at the surface of Jakarta. The analyses were carried out using nonlinear approach. The results were used to develop contour of acceleration at the surface of Jakarta. Finally, the design response spectra for structural design purposes are proposed in this study.

    Full Text Available One hundred forty–five individual lianas were distributed on 2 East facing ridges on the second highest mountain on Java, Mt. Slamet (3418 m., Central Java, Indonesia. Twenty one colonies were observed on small flat areas on ridges. The liana species observed include: Embelia pergamacea, Toddalia asiatica, Elaeagnus latifolia, Schefflera lucida, Vaccinium laurifolium and Lonicera javanica. Diameter of each liana was measured and liana density/flat area calculated. Floristic collecting was under- taken within the elevational gradient of liana distribution. Data suggest an ecotone transition from lower to upper mon- tane forest is observed between 2200 and 2300 m, though forest types are difficult to determine due to disturbance caused by fire at the upper elevations. Observing lianas at these unusuall high elevations with near pluvial rainfall, con- tradict established scientific theory concerning global distribution and abundance of lianas.

    The most extensive and thickestHalimeda bioherms reported from modern seas occur along both open and protected margins of Kalukalukuang Bank, eastern Java Sea (Indonesia). Seismic profiles suggest these features average 20 to 30 m thick (maximum ˜ 50 m) and developed over large areas by coalescence of individual mounds. Bioherm morphologies range from numerous small mounds (˜ 10 20 m diameter) through “hay-stack” features (˜ 100 m diameter) to broad swells. Some modern bank bioherms display surface forms that appear related to onbank flow from Makassar Strait. Upwelling of cold, nutritive water is likely responsible for unusualHalimeda productivity and large bioherm development.

    Full Text Available Begomovirus had been proved as the causal agent of leaf curl disease in tobacco in Indonesia, or commonly in Indonesia called as penyakit krupuk tembakau. Association of Begomovirus with the disease was further confirmed by sequence analysis. Amplification of the virus was conducted following whitefly (Bemisia tabaci Genn. transmission. Fragment of DNA 1.6 kb was amplified by polymerase chain reaction (PCR located within the replication initiator protein gene and coat protein gene (top region. Conserved sequence of stem loop region was found, included nonanucleotide sequence TAATATTAC present in all geminiviruses. Begomovirus associated with leaf curl disease in tobacco showed the closest relationship with Ageratum yellow vein virus - Zimbabwe, a strain of Tobacco leaf curl virus from Southern Africa. It was also known that Begomovirus associated with leaf curl disease in tobacco from Jember, East Java was different from other Indonesian Begomoviruses reported earlier.

    The Brantas is one of Indonesia's most important catchments. It is the "rice bowl" of Java and nationally important for its industrial activity. Surabaya, Indonesia's second largest city, is located at the mouth of the Brantas River which is pivotal to the city's water supply. The challenges associated with the institutional framework for natural resource management in East Java parallels that of many states and provinces around the globe. It is multi-layered and complex. Integrated Catchment Management (ICM) may be defined as "the co-ordinated and sustainable management of land, water, soil vegetation, fauna and other natural resources on a water catchment basis". Over a period of six months, an ICM Strategy was researched and facilitated for the Brantas River Catchment in East Java via a short term advisor attachment. The aim of the Strategy is to improve coordination, co-operation, communication and consistency of government and community efforts towards sustaining the catchment's environmental, economic and social values. The attachment was part of the Pollution Control Implementation (PCI) Project funded by AusAid and the Indonesian Government. The ICM Strategy developed was broad based and addressed the priority natural resource management issues facing the Brantas Catchment. It was co-ordinated by BAPEDALDA, the Provincial Environmental Protection Agency, and developed by all agencies involved in natural resource management in the catchment. Various Universities and Non Government Organisations (NGOs) were also involved in the ICM process which developed the Strategy. At the conclusion of the attachment, a draft ICM Strategy and a proposed institutional framework had been developed. A working group of key agencies was also established to further enhance local "ownership", finalise timescales and implementation responsibilities within the Strategy and bring the institutional arrangements into being through a Governor's Decree.

    Full Text Available Rubella spreads around the world and dangerous especially for pregnant women because it can cause abortion, fetal death or congenital rubella syndrome (CRS almost 90% cases. Spread and identifiation of rubella genotypes in Indonesia is important to ensure the indigenous or importation virus. The purpose of this study was to determine the rubella genotype distribution and spread in West Java in effective prevention efforts. This study was conducted by examining the urine samples of suspect measles patients using WHO protocol through the virus isolation in vero cells, PCR, DNA sequencing, and analysis of the sequencing results. Samples taken from the measles-rubella surveillance program nationwide in 2011 ̶ 2013. Of the 251 urine samples were examined, 32 samples (12.7% were positive. A total of 28 cases (87.5% were genotype 1E while the remaining 4 cases (12.5% were genotype 2B. Rubella virus spread primarily occurs in District of Kuningan, Garut, Tasikmalaya, Bandung City, Cimahi City, and Tasikmalaya City. Prevention of the rubella diseases and CRS surveillance in endemic areas should be priority task to break the chain of transmission.

    Full Text Available The genus Macaca, member of sub-family Cercopithecinae, is the most widely distributed non-human primates in Asian countries. The habitats are strongly influence the dietary variation of the populations. The dietary variation of the macaques reflect ecological plasticity in coping with differences both in availability and abundance of food. The macaques are plastic in taking any kind of food that available in their home range and adjust their behaviour according to its abundance. Here, we present the dietary variation of long-tailed macaques (Macaca fascicularis in the high altitude rain forest of Telaga Warna, West Java, Indonesia. The proportion of their food from natural sources is greater than those from visitors. The natural food consisted of plants, small animals (insects and earthworm, fungi and water from lake. The plant food comprised of 29 species plus a few mosses. The frequency of eating artificial food was influenced by visitors who come for picnic. In this site, the macaques learned that the visiting of tourists is identical with food.

    In Indonesia, Toxoplasma and its associations with blood-borne viruses have been poorly studied. In order to study the association between anti-Toxoplasma antibodies and blood-borne viral antibodies, blood samples from 497 participants (375 inmates from four prisons in Central Java, Indonesia and 122 HIV patients at a Voluntary Counseling and Testing Clinic in Surakarta, Indonesia) were tested for serological markers of Toxoplasma, human immunodeficiency virus (HIV), hepatitis B virus (HBV), hepatitis C virus (HCV), hepatitis D virus (HDV) and human T-lymphotropic virus types I and II (HTLV-1/2). Anti-Toxoplasma IgG and IgM positivity rates were 41.6% and 3.6%, respectively. One point two percent of participants was positive for both anti-Toxoplasma IgG and IgM antibodies. Sixteen point five percent, 11.3%, 2.6% and 2.8% of participants were positive for anti- Toxoplasma IgG combined with anti-HCV antibodies, anti-Toxoplasma IgG combined with anti-HIV antibodies, anti-Toxoplasma IgM combined with anti-HIV antibodes and anti-Toxoplasma IgG combined with both anti-HIV and anti-HCV antibodies, respectively. Anti-Toxoplasma IgM seropositivity was associated with anti-HIV (aOR = 4.3; 95% CI: 1.112-16.204, p = 0.034). Anti-Toxoplasma IgG antibodies were associated with anti-HCV (aOR = 2.8; 95% CI: 1.749-4.538, p < 0.001) and history of injection drug use (aOR = 3.1; 95% CI: 1.905-5.093, p < 0.001). In conclusion, we recommend patients with HIV, HCV infection and injection drug users should be screened for Toxoplasma infection in Indonesia.

    Full Text Available West Java is one of the provinces in Indonesia which is culturally rich and diverse. The cultural wealth in Tatar Sunda (West Java is centered on several areas that serve as the settlement of indigenous communities, from the eastern region of Ciamis, to Sukabumi. Each region has its own cultural uniqueness. Among the cultural heritage which is still in existence and preserved is Kampung Naga. It was a traditional village that firmly preserves its ancestral tradition (karuhun passed down from generation to generation. One of the interesting features of the community of Kampung Naga is the life cycle ritual which they perform with no outside influence. This article will describe the life cycle ritual performed by the indigenous community of Kampung Naga. The ethnographic method approach is used in this study, where the author was directly involved in the process of performing the ritual. Observations, in-depth interviews and participation in any activity were used to collect verifiable data. This research showed that the daur hidup (life cycle ritual performed by the traditional community of Kampung Naga included the rituals for pregnant mother, child birth, circumcision, gusaran, marriage, and prayer to the dead. The ritual carried out by the community is derived from the old Sundanese belief combined with Islamic culture that came in later

    We describe the hominin skull (called here "Bukuran") discovered in the lower Kabuh (or "Bapang") series near Sendangbusik, from the Bukuran area in the Sangiran dome. The fossil, heavily mineralized, consists of the parieto-occipital and the left temporal, and the frontal bones. When combined, those two cranial parts represent a rather complete and well-preserved calvaria. Its stratigraphic position was established after the discovery. A detailed description is presented of the morphological and metric features of the Bukuran calvaria, and comparisons are made with Asian Homo erectus from Indonesia and China. The estimated cranial capacity of Bukuran, the general shape of its cranial vault, its ectocranial structures, and its morphological and metrical characters are in the range of Asian Homo erectus, and show clear affinities with other Indonesian members of the species. We discuss the evolutionary status of the Bukuran calvaria and its implication for hominin history on Java.

    Four strains of Steinernema feltiae from Eastern Java, Indonesia were characterized based on morphometric, morphological and molecular data. In addition, their virulence against last instar Tenebrio molitor and heat tolerance was tested. Infective juvenile have a mean body length ranging from 749 to 792 microm. The maximum sequence difference among the four strains was 7 bp (8.8%) in the ITS and 2 bp (0.3%) in D2D3 regions of the rDNA. All the strains are not reproductively isolated and can reproduce with European strain S. feltiae Owiplant. The lowest LC50 was observed for strain SCM (373) and the highest for S. feltiae strain Owiplant (458) IJs/40 T. molitor. All four strains showed relatively better mean heat tolerance when compared with S. feltiae Owiplant, both in adapted and non-adapted heat tolerance experiments.

    2015-04-01

    Full Text Available The distribution of anthropogenic radionuclides 137Cs was measured from industrial waste effluent of Gresik to Gresik Sea in east Java, Indonesia. The activity of 37Cs detected at all stations was much lower than in northeast Japan both before and after NPP Fukushima accident. This indicated that in Gresik industrials waste did not consist of 137Cs. The lowest activity 137Cs occurred at the station nearest to the industrial waste effluent that contained some particle ions that were able to scavenge 137Cs and then precipate this radionuclide. Furthermore, the greatest 137Cs occured at the station that has high current speeds that stirred up sediment to release 137Cs in seawater as a secondary source. The lowest salinity did not effect on the activity of 137Cs even though the lowest salinity and activity 137Cs occured at the same station

    This paper examines voluntary participation in community forest management, and characterizes how more participation may be induced. We implemented a survey of 571 respondents and conducted a case study in Central Java, Indonesia. The study's novelty lies in categorizing the degrees of participation into three levels and in identifying how socio-economic factors affect people's participation at each level. The analysis finds that voluntary participation responds to key determinants, such as education and income, in a different direction, depending on each of the three levels. However, the publicly organized programs, such as information provision of benefit sharing, are effective, irrespective of the levels of participation. Overall, the results suggest a possibility of further success and corrective measures to enhance the participation in community forest management. Copyright © 2014 Elsevier Ltd. All rights reserved.

    The 29th of May 2006 numerous eruption sites started in northeast Java, Indonesia following to a M6.3 earthquake striking the island.Within a few weeks an area or nearly 2 km2 was covered by boiling mud and rock fragments and a prominent central crater (named Lusi) has been erupting for the last 9.5 years. The M.6.3 seismic event also triggered the activation of the Watukosek strike slip fault system that originates from the Arjuno-Welirang volcanic complex and extends to the northeast of Java hosting Lusi and other mud volcanoes. Since 2006 this fault system has been reactivated in numerous instances mostly following to regional seismic and volcanic activity. However the mechanism controlling this activity have never been investigated and remain poorly understood. In order to investigate the relationship existing between seismicity, volcanism, faulting and Lusi activity, we have deployed a network of 31 seismometers in the framework of the ERC-Lusi Lab project. This network covers a large region that monitors the Lusi activity, the Watukosek fault system and the neighboring Arjuno-Welirang volcanic complex. In particular, to understand the consistent pattern of the source mechanism, relative to the general tectonic stress in the study area, a detailed analysis has been carried out by performing the moment tensor inversion for the near field data collected from the network stations. Furthermore these data have been combined with the near field data from the regional network of the Meteorological, Climatological and Geophysical Agency of Indonesia that covers the whole country on a broader scale.

    2007-01-01

    A begomovirus (2747 nucleotides) and a satellite DNA beta component (1360 nucleotides) have been isolated from Ageratum conyzoides L. plants with yellow vein symptoms growing in Java, Indonesia. The begomovirus is most closely related to Tomato leaf curl Java virus (ToLCJV) (91 and 98% in the total nucleotide and coat protein amino acid sequences, respectively), although the products of ORFs C1 and C4 are more closely related to those of Ageratum yellow vein virus-[Java] (91 and 95% identity, respectively). For this reason, the begomovirus it is considered to be a strain of ToLCJV and is referred to as ToLCJV-Ageratum. The virus probably derives from a recombination event in which nucleotides 2389-2692 of ToLCJV have been replaced with the corresponding region of the AYVV-[Java] genome, which includes the 5' part of the intergenic region and the C1 and C4 ORFs. Infection of A. conyzoides with ToLCJV-Ageratum alone produced no symptoms, but co-infection with DNAbeta induced yellow vein symptoms. Symptoms induced in Nicotiana benthamiana by ToLCJV-Ageratum, ToLCJV and AYVV-[Java] are consistent with the exchange of pathogenicity determinant ORF C4 during recombination.

    Indonesia, an archipelago of 13,500 islands, ranks 5th as the most populous nation in the world. It has 175 million people, 105 million of which live on the island of Java alone. Indonesia has many distinct cultural and linguistic groups. Islam almost wholly replaced Hindu by the end of the 16th century, after arriving in the 12th century. Today 88% of the people are Muslim, while the rest includes Christians, Hindus, Buddhists, and others. The constitution guarantees religious freedom. Indonesia gained independence from the Netherlands in 1949. Indonesia's 1st president, Sukarno, led the rebellion leading to independence and remained in power from 1949-1967. After aligning with Asian communist countries and establishing an authoritarian regime in the early 1960s, the people rebelled, attempted a coup and, in 1967, the People's,s Consultative Assembly named Soeharto as president. He continues to be Indonesia's president and the dominant government and political figure. The constitution provides limited separation of executive, legislative, and judicial power. During the 1970s, the strong economy was based on high oil revenues and an industrial policy which protected domestic industries. Beginning in the 1980s, however, lower energy earnings assisted by low inflation, a downward float against the dollar, and the government eliminating regulatory obstacles turned the economic tide. Even though Indonesia has a larger unrescheduled external debt than any other developing nation, the government is dealing successfully with servicing this debt. Foreign interests participate in the oil and minerals sectors. Indonesia acts on its free and active foreign policy by playing a prominent role in Asian affairs, but avoiding involvement in conflicts among major powers. Indonesia is on friendly terms with its neighbors, and the military does not advocate developing the capability to project its power. The US and Indonesia carry on cordial diplomatic and trade relations

    We describe a gridded daily meteorology dataset consisting of precipitation, minimum and maximum temperature over Java Island, Indonesia at 0.125°×0.125° (~14 km) resolution spanning 30 years from 1985-2014. Importantly, this data set represents a marked improvement from existing gridded data sets over Java with higher spatial resolution, derived exclusively from ground-based observations unlike existing satellite or reanalysis-based products. Gap-infilling and gridding were performed via the Inverse Distance Weighting (IDW) interpolation method (radius, r, of 25 km and power of influence, α, of 3 as optimal parameters) restricted to only those stations including at least 3,650 days (~10 years) of valid data. We employed MSWEP and CHIRPS rainfall products in the cross-validation. It shows that the gridded rainfall presented here produces the most reasonable performance. Visual inspection reveals an increasing performance of gridded precipitation from grid, watershed to island scale. The data set, stored in a network common data form (NetCDF), is intended to support watershed-scale and island-scale studies of short-term and long-term climate, hydrology and ecology.

Gap-infilling and gridding were performed via the Inverse Distance Weighting (IDW) interpolation method (radius, r, of 25 km and power of influence, α, of 3 as optimal parameters) restricted to only those stations including at least 3,650 days (~10 years) of valid data. We employed MSWEP and CHIRPS rainfall products in the cross-validation. It shows that the gridded rainfall presented here produces the most reasonable performance. Visual inspection reveals an increasing performance of gridded precipitation from grid, watershed to island scale. The data set, stored in a network common data form (NetCDF), is intended to support watershed-scale and island-scale studies of short-term and long-term climate, hydrology and ecology.

    An estimated 110,000 babies are born with congenital rubella syndrome (CRS) worldwide annually; a significant proportion of cases occur in Southeast Asia. Rubella vaccine programs have led to successful control of rubella and CRS, and even the elimination of disease in many countries. However, if vaccination is poorly implemented it might increase the number of women reaching childbearing age who remain susceptible to rubella and thereby paradoxically increase CRS. We used an age-structured transmission model to compare seven alternative vaccine strategies for their impact on reducing CRS disease burden in East Java, a setting which is yet to implement a rubella vaccine program. We also investigated the robustness of model predictions to variation in vaccine coverage and other key epidemiological factors. Without rubella vaccination, approximately 700 babies are estimated to be born with CRS in East Java every year at an incidence of 0.77 per 1000live births. This incidence could be reduced to 0.0045 per 1000 live births associated with 99.9% annual reduction in rubella infections after 20 years if the existing two doses of measles vaccine are substituted with two doses of measles plus rubella combination vaccine with the same coverage (87.8% of 9-month-old infants and 80% of 6-year-old children). By comparison a single dose of rubella vaccine will take longer to reduce the burden of rubella and CRS and will be less robust to lower vaccine coverage. While the findings of this study should be informative for settings similar to East Java, the conclusions are dependent on vaccine coverage which would need consideration before applying to all of Indonesia and elsewhere in Asia.

    The island of Java in Indonesia is the most densely populated island on earth, and is situated within one of the most tectonically active regions on the planet. Deadly tsunamis struck Java in 1994 and 2006. We conducted an assessment of tsunami hazards on the south coast of Java using a team of geologists, public health professionals, and disaster education specialists. The social science component included tsunami awareness surveys, education in communities and schools, evacuation drills, and evaluation. We found that the evacuation routes were generally appropriate for the local hazard, and that most people were aware of the routes and knew how to use them. However, functional tsunami warning systems were lacking in most areas and knowledge of natural warning signs was incomplete. We found that while knowledge of when to evacuate improved after our educational lesson, some incorrect beliefs persisted (e.g. misconceptions about types of earthquakes able to generate tsunamis and how far inland tsunamis can reach). There was a general over-reliance on government to alert when evacuation is needed as well as reluctance on the part of local leaders to take initiative to sound tsunami alerts. Many people on earth who are at risk of tsunamis live in areas where the government lacks resources to maintain a functional tsunami warning system. The best hope for protecting those people is direct education working within the local cultural belief system. Further collaboration is needed with government agencies to design consistent and repeated messages challenging misperceptions about when to evacuate and to encourage individuals to take personal responsibility based on natural warning signs.

    One of the most serious problems for tuberculosis (TB) control is non-adherence to TB treatment. We studied the factors influencing non-adherence to TB treatment in Indonesia to inform TB treatment adherence strategies. We con- ducted semi-structured interviews with non-adherent patients and key informants in Jepara, Central Java, Indonesia. Three major themes were found in reasons for non-adherence to TB treatment: 1) knowledge about TB, 2) knowledge about TB treatment and 3) choosing and changing a health care treatment facility. Respondents had an inadequate knowledge about TB and its treatment. Feeling healthy and having financial problems were the most common reasons for TB treatment non-adherence. Respondents sought treatment from many different health care providers, and often changed the treatment facility location. TB treatment adherence might improve by providing better education about the disease and its treatment to those undergoing treatment. Providing information about where to receive treatment and that treatment is free could also improve compliance.

    Maternal health remains a persisting public health challenge in Indonesia. Postnatal complications, in particular, are considered as maternal health problems priority that should be addressed. Conducting adequate care for postnatal complications will improve the quality of life of mothers and babies. With the universal health coverage implementation, the Indonesian government provides free maternal and child health services close to clients at the village level, which include postnatal care. Our study aimed to explore barriers to utilization of postnatal care at the village level in Klaten district, Central Java Province, Indonesia. A qualitative study was conducted in March 2015 - June 2016 in Klaten district, Central Java, Indonesia. We selected a total of 19 study participants, including eight mothers with postnatal complications, six family members, and five village midwives for in-depth interviews. We conducted a content analysis technique on verbatim transcripts of the interviews using open code software. This study found three categories of barriers to postnatal care utilization in villages: mother and family members' health literacy on postnatal care, sociocultural beliefs and practices, and health service responses. Most mothers did not have adequate knowledge and skills regarding postnatal care that reflected how they lacked awareness and practice of postnatal care. Inter-generational norms and myths hindered mothers from utilizing postnatal care and from having adequate nutritional intake during the postnatal period. Mothers and family members conducted unsafe self-treatment to address perceived minor postnatal complication. Furthermore, social power from extended family influenced the postnatal care health literacy for mother and family members. Postnatal care in the village lacked patient-centered care practices. Additionally, midwives' workloads and capacities to conduct postnatal information, education and counseling were also issues. Despite the

    Hominid fossils from Ngandong and Sambungmacan, Central Java, Indonesia, are considered to be the most anatomically derived and youngest representatives of Homo erectus. Nondestructive gamma-ray spectrometric dating of three of these Homo erectus skulls showed that all samples underwent uranium leaching. Nevertheless, we could establish minimum age estimates of around 40ka, with an upper age limit of around 60 to 70ka. This means that the Homo erectus of Java very likely survived the Toba eruption and may have been contemporaneous with the earliest Homo sapiens in Southeast Asia and Australasia.

    Full Text Available Phosphorus Sorption Characteristics of Red Soils from Lampung, West- and Central Java (S.A. Siradz : Red soilis a common name used to identify any soil showing yellowish to reddish colour, these soils mainly occur in tropicaland subtropical regions. The term is frequently used to convey an image of red, infertile, acid soils in the tropics andis associated with tropical and subtropical climates which are characterized by high temperature and humidity. Majorsoil constraints to crop production may include low pH, low available P and high P fixation capacity, toxicity due toAl and sometimes Mn and Fe, deficiencies of N, Ca, Mg, K, and micronutrients e.g. Mo, Zn and Cu, low CEC and lowbase saturation, and very low content of weatherable minerals. The aim of this study was to determine the phosphorussorption characteristics of red soils from Lampung, West Java and Central Java. Soils were sampled at depth of 0-20cm from minimally disturbed sites after discarding the uppermost few cm consisting of an accumulation of litter. Thesamples were air-dried, crushed using a ceramic mortar and pestle and then passed through a 0.5 mm stainless steelsieve. Measurements of P sorption were conducted by equilibrating 200 mg of air dry soil ( West Java and Central Java. Values of pH(NaF, Ald, and exchangeable Ca were most predictive of Psorption in these soils.

    During febrile surveillance in the western Java City of Bandung, Indonesia, a patient with clinical symptoms consistent with hantavirus infection was found to have elevated titers of hantavirus-specific immunoglobulin M (IgM) and IgG antibodies. A subsequent epizoological investigation demonstrated a higher prevalence of hantavirus IgG antibodies in rodents trapped in the vicinity of the patient's home compared with rodents from a control area (13.2% vs. 4.7%, p = 0.036). The Old World Seoul hantavirus was detected by reverse transcriptase-polymerase chain reaction in the organs of 71% of the seropositive rodents tested. This is the first report of a Seoul virus infection in Indonesia supported by clinical, serological, and epizoological evidences. These findings suggest that hantavirus infection should be on the clinical differential diagnosis when acutely ill febrile patients report for care in western Java.

    The LUSI mud volcano has been erupting since May 2006 in a densely populated district of the Sidoarjo regency (East Java, Indonesia), forcing the evacuation of 40,000 people and destroying industries, farmlands, and 10,000 homes. Peak mud extrusion rates of 180,000 m3/d were measured in the first few months of the eruption, which have decreased to water, is erupted at temperatures close to boiling. Gases are periodically released by the bursting of bubbles approximately 3 m in diameter, triggering mud fountains ~20 m in height. No appreciable gas seepage was detected in the quiescent intervals between bubble bursts. Absorption spectrometry in the infrared spectrum reveals that the gas released during explosions consists of 98.5% water vapor, 1% carbon dioxide, and 0.3% methane. On rare occasions, minor amounts of ammonia were also detected. Using simplified plume geometries based on observations, we estimate that LUSI releases approximately 1,500 T/yr of methane, which is equivalent to 0.5% of the yearly methane production from the 2.7 million heads of cattle in the East Java province. We observed explosion periods from 1 to 3 minutes with a median period of 100 s. Two conceptual models for the periodic behavior are assessed: 1) decompressional boiling of water as fluids ascend a pathway to the surface suggests that bubbles form 10s of meters below the surface and continue to expand as they rise; periodicity results from the time to reheat the fluid in the vicinity of bubble formation and 2) gas bubbles are seeded at much greater depths where carbon dioxide exsolves from solution and coalesce in a manner similar to that of slug flow.

    Defining the spectrum of specific thalassemia mutations is an important issue when planning prevention programs in large multi ethnic countries as is Indonesia. In a first attempt to define the prevalence of the common mutations in East Java we selected a cohort of 17 transfusion-dependent patients attending the Dr. Soetomo Hospital, Surabaya, Indonesia. After basic diagnostics we performed direct DNA sequencing for all β-globin genes. The results obtained on 34 independent chromosomes revealed the following prevalence rates: c.79 G>A p. Glu27Lys (Hb E) 47.0%; c.92+5G>C (IVS-I-5 G>C) 20.6%; c.109_110 delC p.Pro37Leu fs X7 [codon 35 (-C)] 17.6%; c.46del T p.Trp16Gly fsX4 [codon 15 (-T)] 5.9%; c.126_129delCTTT p.

Our preliminary results show that the distribution of the prevalent mutations in our cohort is quite homogeneous but with different forms than previously reported. This indicates that more studies on a larger scale and in different geographical areas are needed to refine our provisional results and to characterize the molecular background of the disease in the whole country.

    The 2006 Java Earthquake (Mw 7.2) has generated a tsunami that reached Pangandaran coastal plain with 9.7 m above sea level height of wave. In 2014 we examined the tsunami deposit exposed in shallow trenches along a∼300 m at 5 transect from shoreline to inland on Karapyak and Madasari, Pangandaran. We documented stratigraphically and sedimentologically, the characteristics of Java Tsunami deposit on Karapyak and Madasari and compared both sediments. In local farmland a moderately-sorted, brown soil is buried by a poorly-sorted, grey, medium-grained sand-sheet. The tsunami deposit was distinguished from the underlying soil by a pronounced increase in grain size that becomes finner upwards and landwards. Decreasing concentration of coarse size particles with distance toward inland are in agreement with grain size analysis. The thickest tsunami deposit is about 25 cm found at 84 m from shoreline in Madasari and about 15 cm found at 80 m from shoreline in Karapyak. The thickness of tsunami deposits in some transect become thinner landward but in some other transect lack a consistent suggested strongly affected by local topography. Tsunami deposits at Karapyak and Madasari show many similarities. Both deposits consist of coarse sand that sharply overlies a finer sandy soil. The presence mud drapes and other sedimentary structure like graded bedding, massive beds, mud clasts in many locations shows a dynamics process of tsunami waves. The imbrication coarse and shell fragments of the 2006 Java, tsunami deposits also provide information about the curent direction, allowing us to distinguish run up deposits from backwash deposits.

    In Java, Indonesia, during March 2007-March 2008, 96 farms with scavenging ducks that were not vaccinated against highly pathogenic avian influenza (HPAI) were monitored bimonthly. Bird-level (prevalence among individual birds) H5 seroprevalence was 2.6% for ducks and 0.5% for chickens in contact with ducks. At least 1 seropositive bird was detected during 19.5% and 2.0% of duck- and chicken-flock visits, respectively. Duck flocks were 12.4x more likely than chicken flocks to have seropositive birds. During 21.4% of farm visits,

    Based on light and scanning electron microscopical studies, the following five species of the Philometridae (Nematoda: Dracunculoidea) are described from female specimens collected from marine fishes off the southwestern coast of Java, Indonesia: Philometra lobotidis sp. n. from the abdominal cavity of the Atlantic tripletail Lobotes surinamensis (Bloch) (Lobotidae, Perciformes); Philometra javaensis sp. n. from the abdominal cavity of the immaculate puffer Arothron immaculatus (Bloch et Schneider) (Tetraodontidae, Tetraodontiformes); Philometra psettoditis sp. n. from the musculature of the Indian spiny turbot Psettodes erumei (Bloch et Schneider) (Psettodidae, Pleuronectiformes); Philometroides indonesiensis sp. n. from the musculature of the hound needlefish Tylosurus crocodilus crocodilus (Péron et Lesueur) (Belonidae, Beloniformes); and Philometroides trichiuri sp. n. from the dorsal fin of the largehead hairtail Trichiurus lepturus Linnaeus (type host) and the savalai hairtail Lepturacanthus savala (Cuvier) (both Trichiuridae, Perciformes). All these new species are distinguished from their congeners parasitizing marine fishes by morphological (mainly the shape and structure of the cephalic and caudal ends and of the oesophagus) and biometrical features. Besides previously known Philometra pellucida (Jägerskiöld, 1893) and Philometra ocularis Moravec, Ogawa, Suzuki, Miyazaki et Donai, 2002, they are the only nominal philometrid species recorded from Indonesian waters.

Active faults controlling landform development in tectonically active regions, and it has significantly affected fluvial systems and mountain - front landscapes in the Baturagung Mountain. To assess tectonic activities in the area used quantitative analysis (morphometric). Morphometric analysis consists of 5 parameters geomorphic indices: drainage basin asymmetry (AF), hypsometric curve and integral (Hc and Hi), stream length gradient (SL) index, basin shape index (Bs), and mountain-front sinuosity (Smf). These indices were combined to yield the relative tectonic activity index (RTAI) using geographic information systems (GIS). The result found that RTAI in the study area are divided into three classes: Class 2 (high 0.6% of the watershed area (1.32 km2)); Class 3 (moderate 58.9% (122.1 km2)); and Class 4 (low 40.4% (83.75 km2)). All of morphometric analysis generally indicates this area more influenced by tectonics than erosion. The results are consistent with geomorphological observations.

    No vaccine is currently available for dengue virus (DENV), therefore control programmes usually focus on managing mosquito vector populations. Entomological surveys provide the most common means of characterising vector populations and predicting the risk of local dengue virus transmission. Despite Indonesia being a country strongly affected by DENV, only limited information is available on the local factors affecting DENV transmission and the suitability of available survey methods for assessing risk. We conducted entomological surveys in the Banyumas Regency (Central Java) where dengue cases occur on an annual basis. Four villages were sampled during the dry and rainy seasons: two villages where dengue was endemic, one where dengue cases occurred sporadically and one which was dengue-free. In addition to data for conventional larvae indices, we collected data on pupae indices, and collected adult mosquitoes for species identification in order to determine mosquito species composition and population density. Traditionally used larval indices (House indices, Container indices and Breteau indices) were found to be inadequate as indicators for DENV transmission risk. In contrast, species composition of adult mosquitoes revealed that competent vector species were dominant in dengue endemic and sporadic villages. Our data suggested that the utility of traditional larvae indices, which continue to be used in many dengue endemic countries, should be re-evaluated locally. The results highlight the need for validation of risk indicators and control strategies across DENV affected areas here and perhaps elsewhere in SE Asia.

    Kebumen area is located in central Java Province, Indonesia, where outcrop of Pretertiary rock of old accretion wedge presence. However, the subsurface of the area, limestone, igneous rock, and Conglomeratic-clay of Karangsambung Formation, is poorly understood in subsurface. The current survey of gravity and AMT data is executing to delineate this boundary. The gravity profile and three point AMT is measure for reconnaissance study. The field observations for rock formations are also scrutinized, but the soil is prohibiting to seen more deep in detail. The general result of interpretation and modeling, show reaching depth of one and half kilo meter, the gravity data cover the mayor rock, but the AMT is more significance in better delineating the boundary. Hence the lithology could be distinguished for mélange rock (1000 Ohm.m) and Karangsambung Formation of clay-conglomerate (80 Ohm.m), but also diabase of volcanic-plutonic rock (4000 Ohm.m). The preliminary result shows two mayor results, for limestone and Diabase. Limestone is spread-out on this area, probably the olistolith, and its extensions is more pronounce in the sounding point than the surface observations only. The mysterious of diabase, is more possible as sill product rather than vertical dike.

    Full Text Available Bacteria are the most dominant group of microorganisms in aquatic environments due to their role in organic matter decomposition. Decomposition activity is related to the type and dominance of bacteria in the communities. Therefore, study of bacterial diversity is an important step to understand their role in aquatic ecosystems. This study was to determine bacterial diversity and their physiological characters of bacteria from Bandealit Coast in Jember East Java Indonesia. The bacteria were confirmed by BOX-PCR profile for their genetic polymorphisms. Identification of potential isolate was conducted based on 16S rRNA gene sequence. The result showed that BA011109 isolate was able to utilize D-cellobiose as a sole substrate, indicating its ability to hydrolyse -glucoside bond. This isolate was a potential decomposer in the area considering that most of organic pollutants were from plants that cointain high cellulose. Based on its 16S rRNA gene sequence, this isolate was closely related to Microbacterium esteraromaticum with 100% homology. Further study on quantitative hydrolytic activities is needed to elucidate its role as an organic matter decomposer in aquatic environment.

    The Indonesian island of Java is routinely subjected to intense flooding, drought and related natural hazards, resulting in severe social and economic impacts. Although an improved understanding of the island's hydrology would help mitigate these risks, data scarcity issues make the modeling challenging. To this end, we developed a hydrological representation of Java using the Variable Infiltration Capacity (VIC) model, to simulate the hydrologic processes of several watersheds across the island. We measured the model performance using Nash-Sutcliffe Efficiency (NSE) at monthly time step. Data scarcity and quality issues for precipitation and streamflow warranted the application of a quality control procedure to data ensure consistency among watersheds resulting in 7 watersheds. To optimize the model performance, the calibration parameters were estimated using Borg Multi Objective Evolutionary Algorithm (Borg MOEA), which offers efficient searching of the parameter space, adaptive population sizing and local optima escape facility. The result shows that calibration performance is best (NSE ~ 0.6 - 0.9) in the eastern part of the domain and moderate (NSE ~ 0.3 - 0.5) in the western part of the island. The validation results are lower (NSE ~ 0.1 - 0.5) and (NSE ~ 0.1 - 0.4) in the east and west, respectively. We surmise that the presence of outliers and stark differences in the climate between calibration and validation periods in the western watersheds are responsible for low NSE in this region. In addition, we found that approximately 70% of total errors were contributed by less than 20% of total data. The spatial variability of model performance suggests the influence of both topographical and hydroclimatic controls on the hydrological processes. Most watersheds in eastern part perform better in wet season and vice versa for the western part. This modeling framework is one of the first attempts at comprehensively simulating the hydrology in this maritime, tropical

    Reconstruction of the eruptive history of Sundoro volcano is needed to forecast the probability of future eruptions and eruptive volumes. Sundoro volcano is located in Central Java (Indonesia), 65 km northwest of Yogyakarta, and in one of the most densely populated areas of Indonesia. On the basis of stratigraphy, radiocarbon dating, petrography, and whole-rock geochemistry, we recognize the following 12 eruptive groups: (1) Ngadirejo, (2) Bansari, (3) Arum, (4) Kembang, (5) Kekep, (6) Garung, (7) Kertek, (8) Watu, (9) Liyangan, (10) Kledung, (11) Summit, and (12) Sibajak. The Ngadirejo (34 ka BP) to Kledung (1 ka) eruptive groups are inferred to have been the stratovolcano building phase. Based on compositions of deposits, one or more magma reservoirs of intermediate chemical composition are inferred to have existed below the volcano during the periods of time represented by the eruptive groups. SiO2 of juvenile eruptive products ranges from 50 to 63 wt%, and K2O contents range from high K to medium K. The chemical composition and phenocryst content of eruptive products change with time. The lower SiO2 products contain mainly plagioclase, clinopyroxene, and olivine, whereas the more evolved rocks contain plagioclase, clinopyroxene, orthopyroxene, and rare hornblende and olivine. Our work has defined Sundoro's eruptive history for the period 1-34 ka, and this history helps us to forecast future activity. We estimated that the total amount of magma discharged since 34 ka is approximately 4.4 km3. The average eruption rate over this group ranges from 0.14 to 0.17 km3/kyr. The eruption rate and the frequency of individual eruptions indicate that the volcano has been very active since 34 ka, and this activity in combination with our petrological data suggest the presence of one or more magma reservoirs that have been repeatedly filled and then discharged as eruptions have taken place. Our data further suggest that the volume of the crustal reservoir system has

    Full Text Available High rainfall intensity is major factor governing leaching process, where leaching is often the most important process of N loss from the field and lead to agricultural environmental pollution. In order to measure the movement of mineral-N in soil profile, a field research had been conducted in two sites of center vegetable farming area with six farmer cooperators in Central Java, Indonesia. Regular soil sampling was done from Improve Practice (IP and Farmer Practice (FP treatment for three planting seasons during 2007. Almost all treatments FP applied higher rate of N fertilizer compare to IP, but it was not reflected in N profile. Comparison of predicted and measured mineral N content was simulated using Burns  model, then the closeness of the estimation and measured calculated using Coefficient of Residual Mass (CRM calculation as an indicator with 0 as ideal value. Out of 9 measurements of IP and FP treatment, eight and seven measurements had negative CRM representinga slight overestimation. The NO3- N loss estimated using the Burns model for IP and FP was in average of 67% for IP and 71% for FP of total N fertilizer added or 67% for IP and 76% for FP of total-N surplus, respectively. The calculation of potential nitrate concentration (PNC at 1 m soil depth at the end of the third season showed a high concentration with significant different of IP and FP having mean value of 59.8 and 82.5 mg N L-1. From the gathered data it was obvious that over N fertilization had negative effect to agricultural environment.

    The 29th of may 2006, gas water and mud breccia started to erupt at several localities along the Watukosek fault system, in the Sidoarjo Regency in East java, Indonesia. The most prominent eruption, named Lusi, is still active and covering a surface of nearly 7 km2, resulting in the displacement of ~ 30 000 people. Although the origin and the chemical composition of the erupted fluids have been documented, the mechanical and physical properties of the mud are poorly constrained, and many aspects still remain not understood. Very little is known about the internal dynamics of the Lusi conduit(s). In this study, conducted in the framework of the Lusi Lab project (ERC grant n°308126) we use both analytical and numerical methods to better understand the flow dynamics within the main conduit and to try to explain the longevity of the edifice. The 2D numerical model considers a vertical conduit with a reservoir at its base and solves the stokes equations, discretized on a finite element mesh. Although, three phases (solid, liquid and gas) are present in nature, we only consider the liquid phase. The solid phase is treated as rigid particles in suspension in the liquid. The gaseous phase (methane and carbon dioxide) is treated in an analytical manner using the equations of state of the H2O-CO2 and H2O-CH4 systems. Here, we discuss the effects of density, viscosity, gas concentration and clasts concentration and size on the dynamics of the flow in the conduit as well as implications of the conduit stability.

    Arjuno-Welirang is a twin strato-volcano system located in the East of Java (Indonesia). It features two main peaks: Arjuno (3339 masl) and Welirang (3156 masl). The last recorded eruptive activity took place in August 1950 from the flanks of Kawah Plupuh and in October 1950 by the NW part of the Gunung Welirang. This strato-volcano is characterized by a solfataric area, with high T-vent fumarole at least up to 220°C, located mainly in the Welirang crater zone where sulphur deposits are abundant. In addition, several hot springs vent from the flanks of the volcano, indicating the presence of a large hydrothermal system During July 2015 we carried out a geochemical field campaign on the Arjuno-Welirang volcano-hydrothermal system area sampling water and dissolved gases from the thermal and cold springs located on the flanks of the volcano and from two high-T fumaroles located on the summit area of Welirang. Hydrothermal springs reveal temperatures up to 53°C and pH between 6.2 and 8.2. The hydrothermal springs show a volatile content (mainly CO2 and He) that is several order of magnitude higher than the Air Saturated Waters values (ASW) indicating a strong gas/water interaction processes between waters of meteoric origin and deep volatiles of volcanic origin. The hydrothermal springs have dissolved helium isotopic values with clear magmatic signature (R/Ra around 7) that is remarkably close to the helium isotope values from the fumaroles (R/Ra= 7.30).

Segara Anakan is a significant environmental zone, with many unique ecosystem features, all of which are under threat from illegal land reclamation and timber theft, which have caused great damage. This study analyses how conflict arises between groups and how the rulers interact with villagers in Kampung Laut sur-rounding Nusakambangan Island. The result shows, as Reichel et al. (2009 notes, population growth and lagoon sedimentation indeed have directing to crucial conflicts between groups. However, histori-cal and the rulers approach factors also contribute to Kampung Laut conflicts. Long historical journey contribute to the formation of Kampung Laut villagers’ characters. It is the history of Galuh and Mata-ram Kingdoms’ networks through Babad Pasirluhur and Tanah Jawi in conquering Nusakambangan. More importantly, rulers’ policies and state apparatuses approaches also contribute to the creation of Kampung Laut villagers’ identity. The policies are often inconsistent and create more problems than solutions. Thus, dissatisfaction has directing to the creation of Kampung Laut identity marker as rebel-lions. In short, this hard situation led to conflicts between villagers and rulers. Our study suggest that it is very important to bring the state back in on the isolated and poor area like Kampung Laut Sub-District through more affirmative regional public policies and more over create additional income re-sources, for example eco-tourism that could support its sustainable outcomes.

    One-dimensional (1D) and two-dimensional (2D) magnetotelluric data inversion were conducted to reveal the subsurface resistivity structure beneath the eastern part of a volcano in Central Java, Indonesia. Fifteen magnetotelluric sounding data spanning two lines of investigation were inverted using Occam's inversion scheme. The result depict that there are extensively conductive layer (2-10 ohm meter) below the volcanic overburden. This conductive layer is interpreted as the clay cap resulted from thermal alteration. A higher resistivity layer (10-80 ohm meter) underlies the clay cap and is interpreted as the reservoir whose top boundaries vary between 1000 m above and 2000 m below sea level.

    We examined gonococci isolated in 2004, in East Java and Papua, Indonesia, to review the suitability of ciprofloxacin-based and other treatment regimens. Gonococci from the two provinces were tested in Sydney for susceptibility to penicillin, tetracycline, spectinomycin, ceftriaxone, ciprofloxacin, gentamicin, azithromycin and rifampicin. Of 163 gonococcal isolates from East Java (91) and Papua (72), 120 (74%) of gonococci, 62 (68%) and 58 (80%) from East Java and Papua, respectively, were penicillinase-producing gonococci and 162 displayed high-level tetracycline resistance. Eighty-seven isolates (53%) were ciprofloxacin resistant, 44 (48%) from East Java and 43 (60%) from Papua. All isolates were sensitive to cefixime/ceftriaxone, spectinomycin and azithromycin. Minimum inhibitory concentrations of gentamicin were in the range 0.05-8 mg/L. Sixty-nine gonococci (42%) showed combined resistance, to penicillin, tetracycline and quinolones. Quinolone resistance has now reached unacceptable levels, and their use for the treatment of gonorrhoea in Indonesia should be reconsidered.

    Full Text Available Hundreds of species of wild-caught birds are offered for sale in the bird markets of Java and Bali, Indonesia, to meet the demand for the largely-domestic pet and songbird trade. In the past, owls were offered only in very small numbers in these bird markets but since the release of the Harry Potter series in Indonesia in the early 2000s their popularity as pets has increased. Whereas in the past owls were collective known as Burung Hantu (“Ghost birds”, in the bird markets they are now commonly referred to as Burung Harry Potter (“Harry Potter birds”. We made a retrospective quantitative assessment of the abundance of owls in the bird markets (1979–2010 and conducted 109 surveys in 20 bird markets in 2012–2016 to quantify owls in trade. In the 1980s, 1990s and early 2000s owls were rarely recorded in Indonesia's bird markets, typically one or two and up to five per survey, and frequently no owls were recorded at all. The trade was largely confined to small scops owls. In the late 2000s more species were offered for sale, including barn and bay owls, and larger owl species such as wood-owls, eagle-owls and fish-owls; typically 10 + owls were observed per survey. In recent years, the number of owl species increased even more, and on average we recorded 17 owls per survey, yielding a total of 1810 owls, and in >90% of the surveys owls were present. In the larger bird markets in Jakarta and Bandung typically 30 to 60 owls are on offer of up to 8 species at a time. The number of owls as a proportion of all birds in the markets increased from 0.43% post 2008, suggesting a delayed Harry Potter effect. Over this period, common species have become cheaper and less common ones have become more expensive. The owls are largely, if not exclusively, wild-caught and are sold into the domestic pet market. The release of Harry Potter films and novels in Indonesia coincided with the rise of the Internet and social media and, with some delay, the

    Toxoplasmosis is a concern in both human and veterinary medicine, and the consumption of undercooked meat infected with Toxoplasma gondii is a major risk factor in human infection. Establishing the prevalence of the parasite in food-producing livestock is essential to reduce the risk of human infection. This study aimed to determine the prevalence of T. gondii-specific antibodies in cattle and pigs in Western Java, Indonesia. Serum samples from 598 cattle and 205 pigs from 18 locations in Western Java, Indonesia, were tested for antibodies to T. gondii using an enzyme-linked immunosorbent assay (ELISA). The seroprevalence was 14.6% in pigs and 7.4% in cattle, and significantly more pigs were seropositive compared with cattle (p<0.01). The results of this study suggest that consumption of undercooked meat should be regarded as an important source of infection in people. This study suggests that the risk factors for T. gondii infection in livestock appeared to be different in each location because geographical variation in seroprevalence was observed. The results of this study will facilitate further research to identify and control risk factors for T. gondii in the surveyed locations. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

    This study explores the benefits of multi-objective optimization of Variable Infiltration Capacity (VIC) model for five watersheds in Java, the most populous island in Indonesia. Six objective functions: Nash Sutcliffe Efficiency (NSE), percent bias (PBIAS), logarithmic function of root mean square error (Log-RMSE), predictive efficiency (Pe), percent errors in peak (PEP) and slope of flow duration curve error (SFDCE) were selected as evaluation metrics. These metrics were optimized by tuning four VIC model parameters: infiltration shape parameter (b), fraction of maximum baseflow where nonlinear baseflow begin (Ds), thickness of soil layer 2 (thick2) and thickness of soil layer 3 (thick3). We employed Borg Multiobjective Evolutionary Algorithm (Borg MOEA), an automatic simulation-optimization algorithm, to search for non-dominated solutions. We identified the redundancy between NSE and Log-RMSE, Pe, and PEP through visual inspection of their sensitivity to parameters b and Ds of VIC model and to baseflow index (BFI). Accordingly, we proposed NSE, PBIAS and SFDCE as critical objective functions to represent hydrologic processes in tropical region of Java, Indonesia. Using these three objective functions, we culled the objective functions based on at least - NSE > 0.75, PBIAS resources planning and management.

    An increasing number of claims place hominids outside Africa and deep in Southeast Asia at about the same time that Homo erectus first appears in Africa. The most complete of the early specimens is the partial child's calvaria from Mojokerto (Perning I), Java, Indonesia. Discovered in 1936, the child has been assigned to Australopithecus and multiple species of Homo, including H. modjokertensis, and given developmental ages ranging from 1-8 years. This study systematically assesses Mojokerto relative to modern human and fossil hominid growth series and relative to adult fossil hominids. Cranial base and vault comparisons between Mojokerto and H. sapiens sapiens (Hss) (n = 56), Neandertal (n = 4), and H. erectus (n = 4) juveniles suggest a developmental age range between 4 and 6 years. This range is based in part on new standards for assessing the relative development of the glenoid fossa. Regression analyses of vault arcs and chords indicate that H. erectus juveniles have more rounded frontals and less angulated occipitals than their adult counterparts, whereas Hss juveniles do not show these differences relative to adults. The growth of the cranial superstructures and face appear critical to creating differences in vault contours between H. erectus and Hss. In comparison with adult H. erectus and early Homo (n = 27) and adult Hss (n = 179), the Mojokerto child is best considered a juvenile H. erectus on the basis of synapomorphies of the cranial vault, particularly a metopic eminence and occipital torus, as well as a suite of characters that describe but do not define H. erectus, including obelion depression, supratoral gutter, postorbital constriction, mastoid fissure, lack of sphenoid contribution to glenoid fossa, and length and breadth ratios of the temporomandibular joint. Mojokerto is similar to other juvenile H. erectus in the degree of development of its cranial superstructures and its vault contours relative to adult Indonesian specimens. The

Thus, studies on natural JEV activities in an environment with a small size of pig population have been limited. Here, we surveyed antibodies against JEV in inhabitants of Jakarta and Surabaya located in Java Island (Indonesia), which has a small swine population. Overall, 2.2% of 1,211 sera collected in Jakarta and 1.8% of 1,751 sera collected in Surabaya had neutralizing antibody titers of >or= 1:160 (90% plaque reduction). All the samples with titers of >or= 1:160 against JEV were also examined for neutralizing antibodies against each of four dengue viruses to confirm that JEV antibody prevalences obtained in the present survey were not attributable to serologic cross-reactivities among flaviviruses distributed in Java. These results indicated that people in Java Island are exposed to natural JEV infections despite a small swine population.

    motivator bagi ibu hamil supaya bersedia mengonsumsi tablet zat besi ≥ 90 tablet selama kehamilannya. Kata kunci: Tablet zat besi, kumuh perkotaan, Jabar, DIYABSTRACTBackground:The maternal mortality rate in Indonesia is still quite high. At the provincial level, the maternal mortality vary widely. West Java Province is the largest contributor to maternal mortality with the estimated number 19.8% of all maternal deaths in Indonesia. While the province of Yogyakarta contribution is relatively small (1.1%. Objective:To compare the provision of iron tablets by health workers and pregnant women compliance consume, in urban slums in West Java Province and Yogyakarta. Methods:This study describes and analyzes object that is obtained from the Riskesdas 2010. Results:Based on the characteristics, the majority of mothers in the province of Yogyakarta are in middle education level, working as a self employed/farmer/fisherman/laborer. Meanwhile, in West Java province, mostly just poorly educated and do not have a job. Total ownership of health insurance in the province of Yogyakarta relatively more than in the province of West Java. Based on the scope of the giving of iron tablets, it appears that most of the mothers in the province of West Java and Yogyakarta get iron tablets during pregnancy (84.7% vs 96.0%. However, this condition is much different when viewed from the percentage of pregnant women who consumed at least 90 tablets of iron tablets. Seen that pregnant women who consumed iron tablets ≥ 90 in West Java province only 12.6 percent. By contrast, in the province of Yogyakarta, the consumption of iron tablets ≥ 90 percentage is quite high, reaching 60.0%. Conclusion:Coverage giving iron tablets in both provinces relatively good. However, the consumption of iron tablets ≥ 90 tablets in Yogyakarta Province is relatively better than in West Java Province. Recomendations:It is suggested for the provincial government of West Java and other areas for the promotion and

    Full Text Available Adhikerana AS, Sugardjito J (2010 Characterizing forest reduction in Ketapang district, West Kalimantan, Indonesia. Biodiversitas 11: 46-54. We have characterized deforestation in the Ketapang district forests when we implemented the Orangutan (Pongo pygmaeus wurmbii Conservation in Trans-boundary Landscape between Central and West Kalimantan provinces. For the purpose of evaluating the changes in land use and land cover in the study areas, a series of Landsat imageries have been analyzed. Each of the Landsat imagery data set for all study areas was initially classified using unsupervised classification into 13 different land-cover types. Ground truth checks were undertaken for Ketapang district forests and Sungai Puteri peat swamp forest, from which the results were used for the supervised land use classification of these two study areas. Between 1992 and 2000 there was only small conversion of primary forest into secondary forests. During this period barren land remained extensive about 30.17% of the total area of Ketapang district. Both agriculture and plantation areas substantially increased 56% and 55% respectively during 2003, while at the same time the extent of both primary and peat swamp forests were considerably reduced up to 15% and 28% respectively. The most striking conversion was from secondary forest to agricultural land and from peat swamp forest to swamp areas. A fraction of lowland forest was also converted into oil-palm plantation which was extended with considerable size into agricultural land. The patterns of land use changes detected in this study indicated a number of possible causes that trigger deforestation in this district include, the local government policy and market demand.

    The overall objective of the CASINDO programme is to establish a self-sustaining and self-developing structure at both the national and regional level to build and strengthen human capacity to enable the provinces of North Sumatra, Yogyakarta, Central Java, West Nusa Tenggara and Papua to formulate sound policies for renewable energy and energy efficiency and to develop and implement sustainable energy projects. Energy has a very important role and has become a basic necessity in national sustainable development. Therefore, energy should be used sparingly and in a rational manner so that present and future energy demand can be met. Given the importance of using energy efficiently Government needs to devise a framework regulating the utilization of energy resources through the efficient application of technology and stimulating energy-saving behaviours. The purpose of this technical working group in CASINDO project is to research the steps and policy measures needed to improve the efficiency of electrical energy consumption in the household, industrial, and commercial buildings sector for Central Java. The government's efforts in promoting energy efficiency in Indonesia are still hampered by public awareness factor. This study exists to promote public awareness of energy efficiency by describing the financial benefits and possibilities of savings energies in order to support the government's energy saving program, replacement of old equipment that uses high power consumption with a new low-power one, reduction of unnecessary lighting, appreciation to the people who find and develop energy-efficient power utilization, persuade industries to uses the speed controller driver for production and fan motor to streamline the electrical energy usage.

  2. Variations in Organic Matter Burial and Composition in Sediments from the Indian Ocean Continental Margin Off SW Indonesia (Sumatra - Java - Flores) Since the Last Glacial Maximum

    Global climate change is a mosaic of regional changes to a large extent determined by region-specific feedbacks between climate and ecosystems. At present the ocean is forming a major sink in the global carbon cycle. Organic matter (OM) storage in sediments displays large regional variations and varied over time during the Quaternary. Upwelling regions are sites of high primary productivity and major depocenters of organic carbon (OC), the least understood of which is the Indian Ocean upwelling off Indonesia. In order to reconstruct the burial and composition of OM during the Late Quaternary, we analyzed five sediment cores from the Indian Ocean continental margin off the Indonesian islands Sumatra to Flores spanning the last 20,000 years (20 kyr). Sediments were analyzed for bulk composition, stable carbon and nitrogen isotopes of OM, amino acids and hexosamines and terrestrial plant wax n-alkanes and their stable carbon isotope composition. Sedimentation rates hardly varied over time in the western part of the transect. They were slightly lower in the East during the Last Glacial Maximum (LGM) and deglaciation, but increased strongly during the Holocene. The amount and composition of OM was similar along the transect with maximum values during the deglaciation and the late Holocene. High biogenic opal covarying with OM content indicates upwelling-induced primary productivity dominated by diatoms to be a major control of OM burial in sediments in the East during the past 20 kyr. The content of labile OM was low throughout the transect during the LGM and increased during the late Holocene. The increase was stronger and the OM less degraded in the East than in the West indicating that continental margin sediments off Java and Flores were the major depocenter of OC burial along the Indian Ocean margin off SW Indonesia. Temporal variations probably resulted from changes in upwelling intensity and terrestrial inputs driven by variations in monsoon strength.

  3. Organic chemical composition of mud from the LUSI mud volcano, Sidoarjo, East Java, Indonesia

    Sidoarjo, East Java, Indonesia is the site of LUSI, a terrestrial mud volcano that has been erupting since May 29, 2006. In response to a U.S. Department of State request, the U.S. Geological Survey has been assisting the Indonesian Government to describe the geological and geochemical aspects and potential health risk of the mud eruption. We report here on the organic chemical composition of the mud. Organic chemical analyses were carried out by gas chromatography/mass spectroscopy following organic extraction by microwave-assisted solvent extraction and compound fractionation by adsorption chromatography. There is a petroliferous component in the mud that is fresh, immature, and nonbiodegraded. There is a complete suite of n-alkanes with a bell-shaped pattern typical of fresh petroleum with a Cmax around C20. The alkane content ranges from 0.12 to 1.01 mg/kg dry mud. The presence of certain hopanes (i.e. 17 α,21β(H)-30-norhopane and 17α,21β(H)-hopane) is also indicative of the presence of oil. The proportions of other biomarker compounds (pristane/phytane = 2.4) and the dominance of the C27 sterane (5α(H),14α(H),17α(H)-chlolestane) suggest that oil formed under oxic conditions and has a likely coastal marine or terrigenous source. The presence of oleanane indicates a Cretaceous or younger age for the petrogenic material. These geochemical parameters are consistent with Indonesian oil derived from Tertiary marlstone source rocks that contained kerogen deposited under oxic conditions, probably the upper Miocene Klasafet Formation. Polycyclic aromatic hydrocarbons (PAHs) are present and range in content from 0.1 to 2.2 mg/kg dry mud. The low molecular weight (LMW) PAHs, in particular, naphthalene and methyl-naphthalene are dominant except for perylene which is ubiquitous in the environment. The presence of both parent and higher homologue PAHs indicate a petrogenic rather than combustion source. PAHs are known carcinogens but toxicity data in sediments are

    Transitions in degassing regimes at erupting volcanoes can cause significant changes in magma rheology and the intensity of eruptive activity. The October/November 2010 events at Merapi Volcano, Java, Indonesia began with an intrusive stage (Phase 1), followed by an explosion on October 26th (Phase 2) that removed the pre-existing dome causing deadly pyroclastic density currents (PDCs). This led to rapid ascent of juvenile magma that progressively degassed and crystallized until a large-scale collapse (Phase 3) of the new lava dome on November 5th and associated explosions produced even larger PDCs, killed more citizens, and destroyed several more distal villages. PDC deposits from the two main surge events on October 26th and November 5th, in addition to tephras generated by intermediate explosions, were sampled from numerous locations on the edifice. Secondary ion mass spectrometer (SIMS) depth profiling analyses were performed on free feldspar phenocrysts from the PDC deposits to examine the behavior of volatile elements during the eruptive events of 2010. Phenocrysts were mounted in indium and depth profiled with an O2+ primary ion beam for 2-14 hours. Profiles encounter glass and groundmass on the surface of the crystals before the feldspar is reached, determined from the point at which the B/Si and F/Si signals fall below detection limits. For all samples, the H/Si signal decreases from the glass into the crystal, but the Li/Si signal behaves differently between samples from Phase 2 and Phase 3. In Phase 2 samples, Li/Si ratios are higher in the glass compared to the crystal, revealing a build-up of Li in the groundmass not observed in Phase 3 samples. These observations suggest that Li was able to successfully diffuse out of both the feldspar and the surrounding groundmass in the Phase 3 products, but remained trapped in the groundmass of the Phase 2 products. The build-up of Li in the groundmass, coupled with textural evidence of a late-stage vesiculation

    Anthropometric data are a prerequisite for designing agricultural tools and equipment that enable workers to achieve better performance and productivity while providing better safety and comfort. A set of thirty anthropometric dimensions was collected from a total sample of 371 male and female farm-workers from three different regions (west, central and east) of Java Island, Indonesia. The mean stature is 162.0 cm and 152.5 cm, the sitting height is 82.9 cm and 77.4 cm, and the body weight is 57.1 kg and 52.3 kg for male and female subjects, respectively. The index of relative sitting height (RSH) was 0.51 on average for both male and female subjects. Significant differences are found in most of the anthropometric dimensions between gender and regional data groups as well. Compared with groups of people from several other countries, the anthropometric dimensions of Indonesian people are quite similar to Indian people, but are relatively smaller than Filipino, Chinese, Japanese, British, and American people. An attempt was conducted to illustrate the use of this anthropometric database and ergonomic considerations in refining the design of traditional tools and equipment commonly in use for rice farming operations.

    Lembang Fault is an active fault structure lied beneath a populous area of West Java. It is located at about 9 km from the city centre of Bandung. We have conducted an electromagnetic survey in the area suggested as the zone of Lembang Fault, the Karyawangi Village, West Bandung. Time domain electromagnetic (TDEM) measurements were carried out using two profiles, with a total number of 34 soundings. The TDEM data gives detail information of the shallow conductivity structure down to a depth of 100 m. The 1-D models consist of three layers in the research area. The first layer at the depth between 0 to 3 meters is dominated by low resistivity ( 100 Ωm). The third layer with a resistivity of 10 - 100 Ωm corresponds to sandstone. The model indicates a local fault structure in the study area.

Parade inoculated manually with extracts from symptomatic leaves showed the symptoms indicating the presence of virus. Symptomatic leaf samples tested positive in enzyme linked immunosorbent assay (ELISA with antibodies to group specific Potyvirus and Cucumber mosaic virus (CMV. Total RNA derived from symptomatic leaves was subjected to reverse transcription-polymerase chain reaction (RT-PCR using primers specific to the cylindrical inclusion (CI protein of potyviruses and CMV coat protein (CP specific primers. Pair wise comparison of sequences obtained from cloned RT-PCR products with corresponding nucleotide sequences in the GenBank confirmed the presence of Bean common mosaic virus strain Blackeye (BCMV-BlC and CMV in the symptomatic beans. Sequences of BCMV and CMV isolates from the beans showed maximum nucleotide sequence identities (92-97% and (90%, respectively with BCMV-BIC and CMV isolates from Taiwan. Each virus isolate also clustered closely with corresponding isolates from Taiwan in a phylogenetic analyses. These results provide first evidence of the occurrence of multiple infection of BCMV-BIC and CMV in the yard long been from Bogor, West Java.

    A fossil femur excavated by Eugène Dubois between 1891-1900 in the Lower/Middle Pleistocene bonebed of the Trinil site (Java, Indonesia) was recognised by us as that of a Hylobatidae. The specimen, Trinil 5703 of the Dubois Collection (Leiden, The Netherlands), has the same distinctive form of fossilization that is seen in many of the bonebed fossils from Trinil in the collection. Anatomical comparison of Trinil 5703 to a sample of carnivore and primate femora, supported by morphometric analyses, lead to the attribution of the fossil to gibbon. Trinil 5703 therefore provides the oldest insular record of this clade, one of the oldest known Hylobatidae fossils from Southeast Asia. Because living Hylobatidae only inhabit evergreen rain forests, the paleoenvironment within the river drainage in the greater Trinil area evidently included forests of this kind during the Lower/Middle Pleistocene as revealed here.

    Neospora caninum can cause fetal abortion and neonatal mortality in cattle, and is a cause of economic concern worldwide. This study aimed to determine the prevalence of Neospora caninum-specific antibodies in cattle from Western Java, Indonesia. Serum samples from 991 cattle from 21 locations were tested for antibodies to N. caninum by using an enzyme-linked immunosorbent assay (ELISA) on the basis of recombinant NcSAG1. The overall seroprevalence was 16.6%, ranging from 0 to 87.5% in the sampled locations. The results of this study indicate latent infection rates of sampled animals were different in each location. Further studies are necessary to elucidate the relationship between N. caninum infection and abortion in cattle, and to identify risk factors for infection in high-prevalence environments.

    Geological structure in the region of central Java is very important for understanding its tectonic setting. The presence of several active volcanoes such as Mt. Merapi, Mt. Sumbing and Mt. Lawu, as well as the Kendeng Basin and Opak fault all contribute to the complex geology of central Java. Understanding some of the characteristics of the geological structure can be improved using a geophysical approach such as seismic tomography. In this study we show the image of the subsurface in central Java obtained from ambient seismic noise tomography. We use simultaneously operated 134 short period and broadband seismometers from the Merapi Amphibious Experiment (MERAMEX) network covering a region of 150 x 200 km around central Java and Yogyakarta. More than 5000 Rayleigh wave component of the Green's function are extracted from cross-correlations of available station pairs. We filter the retrieved Green's functions with a phase-matched filter to measure Rayleigh wave group dispersion at periods between 0.5 and 20 s. We apply a 2-D nonlinear iterative tomographic method for inverting the measured travel times. The results are then used to create group velocity perturbation maps. The velocity perturbation maps show a high correlation with local tectonic features. The Kendeng basin and active volcanoes in the central part of central Java are clearly imaged with lower group velocities and the southern part has the carbonate region is marked with higher group velocities.

    In order to elucidate the genetic relationships and reproductive-isolation mechanisms among the Fejervarya limnocharis complex from Indonesia and other Asian countries, allozyme analyses and crossing experiments were carried out using 208 individuals from 21 localities in eight Asian countries. The allozyme analyses revealed that 17 enzymes examined were controlled by genes at 27 loci, and that 7.9 phenotypes were produced by 5.2 alleles on average. The two species recognized in F. limnocharis sensu lato from Southeast Asia (i.e., F. limnocharis sensu stricto and F. iskandari) were found to occur sympatrically at three localities (Bogor, Cianjur and Malingping), all on Java, Indonesia. Fejervaya iskandari was dominant at each of these localities and showed substantial geographic genetic variation. Laboratory-produced hybrids between F. limnocharis and F. iskandari from Java became underdeveloped and died at the tadpole stage, suggesting that these species are completely isolated by hybrid inviability. Hybrids between topotypic F. limnocharis and the Malaysian and Japanese conspecific populations developed normally to metamorphosis. Likewise, hybrids between topotypic F. iskandari and the Thailand and Bangladesh conspecific populations also showed normal viability throughout larval development. The present allozyme analyses and crossing experiments strongly suggested the presence of two distinct forms, the large type and the small type, in the F. limnocharis complex from Asia, and further subdivision of the large type into the F. limnocharis assemblage and the F. iskandari assemblage. The small type was found in samples from India, Thailand, Bangladesh and Sri Lanka, and included at least three different species. The sample from Pilok, Thailand, was considered to represent an undescribed species.

    To help guide surveillance and control of highly pathogenic avian influenza subtype H5N1 (H5N1-HPAI), the Food and Agriculture Organization of the United Nations in 2004 devised a poultry farm classification system based on a combination of production and biosecurity practices. Four "Sectors" were defined, and this scheme has been widely adopted within Indonesia to guide national surveillance and control strategies. Nevertheless, little detailed research into the robustness of this classification system has been conducted, particularly as it relates to independent, small to medium-sized commercial poultry farms (Sector 3). Through an analysis of questionnaire data collected as part of a survey of layer farms in western and central Java, all of which were classified as Sector 3 by local veterinarians, we provide benchmark data on what defines this sector. A multivariate analysis of the dataset, using hierarchical cluster analysis, identified three groupings of the farms, which were defined by a combination of production-and biosecurity-related variables, particularly those related to farm size and (the lack of) washing and disinfection practices. Nevertheless, the relationship between production-related variables and positive biosecurity practices was poor, and larger farms did not have an overall higher total biosecurity score than small or medium-sized ones. Further research is required to define the properties of poultry farms in Indonesia that are most closely related to effective biosecurity and the prevention of H5N1-HPAI.

    The purpose of this study was to investigate the prevalence of house rat zoonotic intestinal parasites from Surabaya District, East Java, Indonesia that have the potential to cause opportunistic infection in humans. House rat fecal samples were collected from an area of Surabaya District with a dense rat population during May 2015. Intestinal parasites were detected microscopically using direct smear of feces stained with Lugol's iodine and modified Ziehl-Neelsen stains. The fecal samples were also cultured for Strongyloides stercoralis. Ninety-eight house rat fecal samples were examined. The potential opportunistic infection parasite densities found in those samples were Strongyloides stercoralis in 53%, Hymenolepis nana in 42%, Cryptosporidium spp in 33%, and Blastocystis spp in 6%. This is the first report of this kind in Surabaya District. Measures need to be taken to control the house rat population in the study area to reduce the risk of the public health problem.

    Full Text Available Agricultural and plantation activities in Indonesia, especially in Semarang, Central Java, Indonesia rely on water supply from the rainfall. The rainfall in the future is basically influenced by rainfall patterns, humidity and temperature in the past. In this case, Vector Autoregression (VAR multivariate model is applied to forecast the rainfall in the future, in which all along Indonesian Agency for Meteorology, Climatology and Geophysics (BMKG generally uses ARIMA model (Autoregressive Integrated Moving Average to carry out the same thing. The study applied the data, comprising the data of rainfall, humidity and temperature taken on a monthly basis during 2001-2013 periods from 5 measurement stations. Plotting of rainfall forecast result with VAR method is portrayed in the form of isohyet contour map to see the correlation between rainfall and coordinates of the area of the rainfall. The forecast result shows that VAR method is quite accurate to use for rainfall forecast in the study area as well as better than ARIMA method to forecast the same thing as having smaller Mean Absolute Error (MAE and Mean Absolute Percentage Error(MAPE.

    Full Text Available This article investigates gender construction in Islamic boarding schools or 'pesantren' Semarang, Indonesia (Al-Islah and Al-Anshor and Johor, Malaysia (Mahad and Marsah. It was found that despite their different countries and customs, the schools in Indonesia and Malaysia show some similarities, especially in terms of the teaching of Islamic jurisprudence and thei perceptions of the rights of men and women as explained in the Qur'an. However, they differ, especially in terms of the implementation of these in their daily lives. In Johor, Malaysia, men are responsible for activities outside of the households whereas women are in charge of the domestic chores. In Semarang, Indonesia, however, women, despite their household responsibilities, can also work outside. In addition, in terms of polygamy, most people in Johor support it as long as it does not break any religious laws.

  1. Tetanus toxoid immunization campaign in West Nusa Tenggara, Indonesia.

    1985-01-01

    A tetanus toxoid (TT) immunization campaign was carried out in Central Lombok district of Indonesia in the province of West Nusa Tenggara (NTB) from January to April 1985. A coverage rate of 93% for 2 doses was obtained among women of childbearing age. This paper summarizes the major components of the activity, discussing some of the strengths and weaknesses of the campaign. The major objective of this crash campaign was to raise the tetanus immunity level throughout the fertile age group and thus to achieve a marked reduction in the incidence of neonatal tetanus. A draft protocol for the campaign was developed by national and provincial health staff. The governor of NTB pledged the full support of the provincial administrative apparatus, and funds, equipment, and vaccine were guaranteed at the national level. Commitments of support were received from all relevant sectoral departments at provincial and district levels. About 2 weeks before the vaccination activities began, PKK cadres -- about 6000 women in Central Lombok district -- were provided with forms to take a census of all fertile women in their respective areas. This information was consolidated at the village level, where a serial number was assigned to each name. The enumeration forms were later used as vaccination registers. The number of women identified in each village was reported to the appropriate health center for use in planning vaccine requirements and the deployment of manpower. 2 or 3 days prior to the scheduled vaccination session, PKK cadres again visited all women on their census list to inform them of the place and time of the vaccinator's visit and to distribute appointment cards which carried serial numbers matching those on the census list. The 31 vaccinators were newly qualified nursing school graduates awaiting their 1st government postings. They were given a 2-day orientation course on campaign strategy and methods, and their work schedule was explained. First-line technical

    Diet has a strong relationship with food culture and changes in it are likely to be involved in the pathogenesis of newly emergent degenerative diseases. To obtain in-depth opinions about the food culture of Minangkabau people, focus group discussions were conducted in a Minangkabau region, represented by four villages in West Sumatra, Indonesia, from January to March 1999. The members of the discussion groups were principally women aged from 35 to 82 years old. Minangkabau culture is matriarchal and matrilineal which accounts for female gender dominants in the discussions. Rice, fish, coconut and chilli are the basic ingredients of the Minangkabau meals. Meat, especially beef and chicken, is mainly prepared for special occasions; pork is not halal and therefore not eaten by Muslim Minangkabau people; and for reasons of taste preference and availability, lamb, goat and wild game are rarely eaten. However, rendang, a popular meat dish, has been identified as one of the Minangkabau food culture characteristic dishes. Vegetables are consumed daily. Fruit is mainly seasonal, although certain kinds of fruit, such as banana, papaya and citrus, can be found all year around. Coconut has an important role in Minangkabau food culture and is the main source of dietary fat. While almost all food items consumed by the Minangkabau can be cooked with coconut milk, fried food with coconut oil is considered to be a daily basic food. Desiccated coconut is also used as a food ingredient on about a weekly basis and in snack foods almost every day. Although there have been no changes in food preparation and there is a slight difference in taste preference between the young and the old generations, there has been a dramatic shift in food preferences, which is reflected in the changing percentage of energy consumed over the past 15 years. The traditional combination of rice, fish and coconut in Minangkabau culture goes back hundreds of years, long before the emergence of the degenerative

  3. Restoring State Control Over Forest Resources Through Administrative Procedures: Evidence From a Community Forestry Programme in Central Java, Indonesia

    2012-01-01

    Full Text Available In recent years, community forestry has emerged as a means to reform power constellations with regard to forest governance. Through community forestry, the central state promised to devolve several forest rights to local communities and encouraged them to get involved in decision making processes and the implementation of forest activities. However, experience in some countries indicates that the implementation of community forestry programmes is rarely followed by genuine power devolution to local forest users. Instead, these programmes may even serve as a means to retain or restore the central state’s control over forests. Using a case study of a community forestry programme implemented in Java, Indonesia, by a state forest company, this paper argues that the implementation of community forestry is also driven by the state’s interests to regain control over the forests. Research in eight villages in Central Java province reveals that the community forestry programmes are carefully structured according to numerous administrative procedures and estab- lish a mode of control through a bureaucratic design. ----- In den letzten Jahren hat sich community forestry als Mittel zur Reform von Machtkonstellationen in Bezug auf die Verwaltung von Wäldern herausgebildet. Der Zentralstaat versprach durch community forestry bestimmte Waldrechte an lokale Communities abzugeben und ermutigte sie, sich an Entscheidungsprozessen und der Implementierung von Forstaktivitäten zu beteiligen. Erfahrungen in einigen Ländern zeigen jedoch, dass die Implementierung von community forestry-Programmen selten mit einem tatsächlichen Machttransfer an lokale ForstnutzerInnen einhergeht, sondern diese Programme sogar als Mittel zur Rückgewinnung von zentralstaatlicher Kontrolle über Wälder dienen können. Anhand eines Fallbeispiels eines community forestry-Programms, das in Java, Indonesien, von einem staatlichen Forstunternehmen implementiert wird, argumentiere ich

    Geochemical mapping based on the stream sediment method has been carried out in the whole of Java Region by the Centre for Geological Survey. The Regional Geochemistry Bandung Quadrangle as part of West Java Region has been mapped in 1:100.000 scale map, base on the Geological Map of Bandung Quadrangle. About 82 stream sediment samples collected and sieved in the 80 mesh sieve fraction during the field work session at 2011. This fraction was prepared and analysed for 30 elements by X-ray fluorescence spectrometry at the Centre for Geological Survey Laboratory. There are some elements indicating significant anomaly in this region, and it is important to determine the present abundance and spatial distribution of the elements for presuming result from natural product or derived from human activities. The volcanic products (Tangkuban Perahu Volcano, Volcanic Rock Complex and Quarternary Volcanic-Alluvial Deposit) are clearly identified on the distribution of As, Ba, Cl, Cu, Zr and La elements. However Mn, Zn, V and Sr are related to precipitation in the Tertiary Sediments, while the influence of human activities are showing from a geochemical map of Cl, Cr, Cu, Pb and Zn that show scattered anomalies localized close to the cities, farming and industries.

    Full Text Available The production performance of Holstein-Friesian cows in West Java was evaluated in two areas, Cisarua district (Bogor and Tanjungsari district (Sumedang. In Cisarua the evaluation was made on 175 cows with different stage of lactation (2 - 11 months. Feed offered, both forage and concentrate, milk production and chess girth were measured from each animal for 24 h only. Date of calving, date of service and stage of pregnancy were recorded by interviewing the farmers . In Tanjungsari the study was conducted on 102 postpartum cows . Milk production and chess girth were measured at the beginning of the study and then once a month (morning and afternoon milking for 3 months. Milk production was 3,700 1 and 3,400 1 per lactation with declining rate of 0 .03 and 0 .05 1/d for Cisarua and Tanjungsari area respectively. The ratio of concentrate : forage consumption was 1 and 1 .4 in Cisarua and in Tanjungsari respectively, and the ratio was reduced as milk production declined . The efficiency of conversion of feed ME to milk yield was approximately the same (0.12 1/MJ in both location . The proportion of cows lost weight in Cisarua during the first three months was lower (46 % as compared to that in Sumedang (77 %. Approximately 68 % of the population have conception rate (CR > 50 % , the remaining should be culled, 24 % have low CR and 8 % have days open > 150 days . From 61 cows observed, 71 % and 21% have a projected calving interval of 12 months and 13 - 14 months respectively . It can be concluded that milk production and reproduction efficiency of Holstein'cows in West Java are considered low.

    In the first paper of this two-part series on the development of a water sustainability index for West Java, a conceptual framework of West Java Water Sustainability Index (WJWSI) was developed. It consists of three main parts: components, indicators/sub-indicators and threshold values. This second paper of the series presents the application of the Delphi technique, followed by in-depth interviews with selected key experts, to refine the conceptual WJWSI framework. The Delphi application includes the design of the questionnaires, the selection of respondents, the distribution and collection of the completed questionnaires and the analysis of data. After Round One of the Delphi application, the respondents reached consensus for all proposed components in the conceptual framework. However, some modifications to the components were also suggested by few respondents. Regarding the indicators/sub-indicators, consensus for 9 of the proposed 12 indicators was reached, and 5 new indicators were suggested. For the threshold values, consensus was reached for threshold values of 5 indicators. In Round Two of the Delphi application, respondents were asked questions related to results from Round One, which include the modification on the components, indicators/sub-indicators which have not been agreed, and newly suggested indicators/sub-indicators and threshold values. Results of Round Two show that modifications on the components were agreed, and consensus was reached for 8 out of the proposed 9 indicators/sub-indicators. In terms of its components and indicators, the framework was then finalised in the in-depth interview with four key experts, selected from different respondent categories. For the threshold values not yet finalised, further study will be carried out, as there was not much input from the respondents in the Delphi application and the in-depth interview.

    Full Text Available The morphology of sporophyte, the type of reproduction, and cytology of Pteris had been reported, while the gametophyte morphology of Pteris in Java island has not been studied yet. The objective of this study was to describe the gametophyte morphology and development of P. biaurita, P. ensiformis, P. exelsa, P. longipinnula, P.tripartita, and P. vittata in Java island. Spores were obtained from fertile leaves of Pteris plants originated from several locations in Java island. The number of spores per sporangium was counted from fresh fertile leaves with mature sporangia. As much as 0.002 g spores was sown in a transparent box with sterile medium contain of vermiculite, sphagnum moss, and perlite with ratio 2:2:1. The gametophyte development of each species was observed under a microscope every 7 days. The spores of P. ensiformis were germinated faster, ten days after sowing, while the spores of P. longipinnula were germinated slower, 18 days after sowing. The pattern of spore germination is Vittaria-type. The development of gametophyte is Ceratopteris-type in common, but in a few cases is the Adiantum-type. The gametophyte development of observed Pteris species is varied in six characters including the number of filament cell, germinated time, the formation time of notch and gametangia, margin shape, and development type.

    Full Text Available INTRODUCTION: Streptococcus pneumoniae is a worldwide occurring pathogen Nasopharyngeal carriage of Streptococcus pneumoniae precedes pneumonia and other pneumococcal diseases in the community. Little is known about S. pneumoniae carriage in Indonesia, complicating strategies to control pneumococcal diseases. We investigated nasopharyngeal carriage of S. pneumoniae in Semarang, Indonesia. METHODS: A population-based survey was performed in Semarang, Indonesia. Nasopharyngeal swabs and questionnaires were taken from 496 healthy young (6-60 month-old children and 45-70 year-old adults. RESULTS: Forty-three percent of children aged 6-60 months and 11% of adults aged 45-75 years carried S. pneumoniae. Determinants of carriage were being a child (OR 7.7; 95% CI = 4.5-13.0, passive smoking (OR 2.1; 95% CI = 1.3-3.4, and contact with toddler(s at home (OR 3.0; 95% CI = 1.9-4.7. The most frequent serotypes found were 6A/B and 15B/C. The current commercially available vaccines cover <50% serotypes found in children. Twenty-four percent of S. pneumoniae strains were penicillin non-susceptible, and 45% were resistant to cotrimoxazol. CONCLUSIONS: The limited coverage of commercially available vaccines against the serotypes found in this population, and the high proportion of non-susceptibility to penicillin and cotrimoxazol suggest the need for region-specific information and strategies to control S. pneumoniae.

    Malaria has been targeted for elimination from Indonesia by 2030, with varying timelines for specific geographical areas based on disease endemicity. The regional deadline for malaria elimination for Java island, given the steady decrease of malaria cases, was the end of 2015. Purworejo District, a malaria-endemic area in Java with an annual parasite incidence (API) of 0.05 per 1,000 population in 2009, aims to enter this elimination stage. This study documents factors that affect incidence and spatial distribution of malaria in Purworejo, such as geomorphology, topography, health system issues, and identifies potential constraints and challenges to achieve the elimination stage, such as inter-districts coordination, decentralization policy and allocation of financial resources for the programme. Historical malaria data from 2007 to 2011 were collected through secondary data, in-depth interviews and focus group discussions during study year (2010-2011). Malaria cases were mapped using the village-centroid shape file to visualize its distribution with geomorphologic characteristics overlay and spatial distribution of malaria. API in each village in Purworejo and its surrounding districts from 2007 to 2011 was stratified into high, middle or low case incidence to show the spatiotemporal mapping pattern. The spatiotemporal pattern of malaria cases in Purworejo and the adjacent districts demonstrate repeated concentrated occurrences of malaria in specific areas from 2007 to 2011. District health system issues, i.e., suboptimal coordination between primary care and referral systems, suboptimal inter-district collaboration for malaria surveillance, decentralization policy and the lack of resources, especially district budget allocations for the malaria programme, were major constraints for programme sustainability. A new malaria elimination approach that fits the local disease transmission, intervention and political system is required. These changes include timely

    A storm tide event (the sum of the astronomical tide and the storm surge) along the southern coast of Java has been simulated by using a two-dimensional (2D) ocean model (barotropic version of Mike 21). In this study, we simulated the storm surge generated by the Cyclone Jacob during 2-12 March 2007 and Cyclone George during 3-9 March 2007 in northwestern coastal waters of Australia. The applied model based on an unstructured grid approach employs finite volume method to solve the governing equations. The applied model allows for a highly flexible discretization of the model domain. This is demonstrated by grid sizes, which vary from 50km in the deep ocean to a considerably higher resolution of about 150m in the coastal area. To simulate water run-up and inundation processes, flooding and drying (FAD) capabilities of the model were enabled. The model domain covers the northeastern part of the Indian Ocean and the coastal areas of the southern part of Java. The storm tide event was simulated by imposing tidal elevations at the open boundaries, 6-hourly wind and air pressure data. Tidal elevation data was derived from the tide model driver (TMD), while wind and air pressure data were obtained from NCEP (National Centers for Environmental Prediction). The weekly TOPEX Poseidon Sea Level Anomaly (SLA) was used to validate the model results of surge height. The simulation results show that the storm tides had attacked and inundated coastal areas of the southern part of Java. Nusa Kambangan (a part of Cilacap Regency) experienced the highest surge among the other stations, about 0.19m, at 17:00 UTC on 7 March 2007. Maximum distance of storm tide flooding occurred at Telereng Cape (about 500.4m), Penanjung Bay (about 835.2m), and Pelindu Cape (about 710.6m) in which each of those areas representing the western, central, and eastern part of the the southern coast of Java, respectively. Meanwhile, water run-up heights at the locations where the maximum distance of flooding

    To characterise commensal Escherichia coli and other Enterobacteriaceae with reduced susceptibility to cefotaxime that were collected in a large survey carried out among 3995 patients and healthy persons in two urban regions on Java, Indonesia, in 2001-2002. The putative extended-spectrum β-lactamase (ESBL)-producing Enterobacteriaceae were analysed using double-disk synergy tests, isoelectric focusing, PCR assays, DNA sequencing, and pulsed-field gel electrophoresis (PFGE). On the day of discharge after five or more days of hospitalisation, at least 95 of 999 (9.5%) patients carried ESBL-positive Enterobacteriaceae as dominant faecal flora. Six patients were simultaneously colonised with E. coli and Klebsiella pneumoniae isolates with ESBL activity. On admission, only 6 of 998 (0.6%) patients were colonised. Faecal carriage of ESBL-producing Enterobacteriaceae among healthy persons or persons visiting a public health centre was not detected. The 107 ESBL-positive strains included 68 E. coli, 35 K. pneumoniae, and four other Enterobacteriaceae. bla(CTX-M-15) was the most prevalent ESBL in both E. coli (47.1%) and K. pneumoniae (45.7%), but the E. coli O25b-ST131 clone was virtually absent. Other ESBL types found were: SHV-2, -2a, -5, -12, CTX-M-3, -9, -14, and TEM-19. PFGE revealed extensive genetic diversity among the isolates. In 2001-2002, faecal carriage of ESBL-producing Enterobacteriaceae as dominant flora in Indonesia was almost exclusively hospital-associated. The presence of various bla(ESBL) genes and the extensive genetic diversity among isolates argue against a single/dominant strain outbreak. © 2012 Blackwell Publishing Ltd.

    PT. Holcim Indonesia Tbk is a well-known company for cement production in Cilacap, Central Java, Indonesia. In cement manufacturing, certain raw materials such as limestone, claystone and other supplementary materials are required. In a mean time, the company is conducting claystone mining to support the cement industry. Currently, the exploitation has covered the area of approximately 103 ha. Due to the increment need of more claystone to achieve the expecting amount of cement production, the company plans to extend existing mining site up to 250 ha with maximum depth of +10m above the sea level. However, such development may eventually lead to major slope failures which essentially affect the sustainability and the safety of the mine. Understanding that various negative impacts may appear during the mining operation, which possibly result in personal injury, potential life loss, property damage and other socio-economic consequences, it is crucial to assess slope stability conditions of the mining pit to ensure safety of the mine. The study is mainly focused on analysis of the rock mass behaviours under specific geological control and earthquake trigger through the application of finite element method. Based on the assessment result, the zone where covered by discontinuous rock mass, absorbent lithology and steep slope geometry in combination with presence of groundwater, is estimated to be potential to slope movement in form of rock falls and/or rock slides which could be possibly predicted to occur as a consequence of heavy rainfall intensity, un-controlled slope excavation and ground vibration. And, the stable slope inclination is suggested not to be steeper than 60˚, with the maximum width of 3m and maximum height of 6m.

    Delineating the crustal structure of central Java is crucial for understanding its complex tectonic setting. However, seismic imaging of the strong heterogeneity typical of such a tectonically active region can be challenging, particularly in the upper crust where velocity contrasts are strongest and steep body wave ray paths provide poor resolution. To overcome these difficulties, we apply the technique of ambient noise tomography (ANT) to data collected during the Merapi Amphibious Experiment (MERAMEX), which covered central Java with a temporary deployment of over 120 seismometers during 2004 May-October. More than 5000 Rayleigh wave Green's functions were extracted by cross-correlating the noise simultaneously recorded at available station pairs. We applied a fully non-linear 2-D Bayesian probabilistic inversion technique to the retrieved traveltimes. Features in the derived tomographic images correlate well with previous studies, and some shallow structures that were not evident in previous studies are clearly imaged with ANT. The Kendeng Basin and several active volcanoes appear with very low group velocities, and anomalies with relatively high velocities can be interpreted in terms of crustal sutures and/or surface geological features.

    The U.S. is recognized globally for its leadership in science and technology. Scientific cooperation is an important tool in the application of "smart power" to create partnerships with countries around the world. The State Department's Office of the Science Advisor works to increase the number of scientists engaged in diplomacy through coordination with the American Association of the Advancement of Science, Science Diplomacy Fellows, Jefferson Science Fellowships, and the Embassy Science Fellows Program. In addition, scientific cooperation occurs at all levels through relationships between science faculties, scientific institutions, and technical assistance programs. President Obama made increased collaboration on science and technology, the appointment of new science envoys, and the opening of new scientific centers of excellence in Africa, and the Middle East, and Southeast Asia a central component of his Cairo speech. Indonesia, science diplomacy crosses myriad programs. Negotiations on a bilateral Science and Technology Agreement between the U.S. and Indonesia will begin in September. USAID provides assistance in volcano/earthquake monitoring, forest management and reduction of illegal logging with DOJ, clean water and sanitation, the Coral Triangle Initiative to sustain Indonesia's marine biodiversity, coastal resilience with NOAA, clean energy, clean air initiatives with EPA, and emergency disaster response. The LUSI mudflow disaster, located just 27 km south of the U.S. Consulate in Surabaya, has already displaced thousands, has contributed to environmental degradation, and threatens critical transportation infrastructure. U.S. assistance to Indonesia to mitigate the impact of the LUSI mudflow on surrounding communities and the environment was complicated by questions surrounding the cause of the mud: industrial accident or natural disaster. But, the devastating impact on the local environment, population, and businesses was unquestioned. Experts from the

    Redox-sensitive elements in sediments,such as manganese (Mn),vanadium (V),molybdenum (Mo),and uranium (U),are promising indicators of past redox conditions during sedimentation and early diagenesis.However,in the Ontong Java Plateau,west equatorial Pacific,there are sparse datasets of redox-sensitive elements in sediment cores.Here,we present a 250 ka record of redox sensitive elements from a 460 em gravity core at site WP7 (3°56'S,156°E,water depth 1 800 m),which was recovered from the southwest Ontong Java Plateau during the 1993 cruise of R/V Science Ⅰ of the Institute of Oceanology,Chinese Academy of Sciences (IOCAS).Relative to the Post-Archean Australian Shale (PAAS),authigenic Mn,cobalt (Co),nickel (Ni),Mo,V,U,and cadmium (Cd) were found at constantly low levels except when peaks occurred at several depth intervals.Manganese,Co,Ni,and Mo concentrations were elevated at 25-35 cm due to Mn redox cycling.The core was divided into three distinct sections,the top 0-25 cm being oxic,a suboxic section at 25-35 cm and from 35- 460 cm which was anoxic.Differential authigenic enrichments of Co,Ni,Mo,V,U,and Cd at the same depth intervals were observed indicating that the enrichments happened during sedimentation or diagenesis and suffered no post settlement redox changes.Therefore,no significant changes in redox conditions during sedimentation must have happened.The water at depth on the Ontong Java Plateau during past 250 ka must have been well oxygenated,possibly resulted from the more or less continuous presence of oxygen-rich deep water like the modem Antarctic Intermediate Water (AAIW) and Antarctic Circumpolar Water (ACW); while it's slightly less oxygenated in glacial intervals,possibly due to ventilation weakening and/or the surface productivity increase.

    Understanding healthcare-seeking patterns for respiratory illness can help improve estimations of disease burden and inform public health interventions to control acute respiratory disease in Indonesia. The objectives of this study were to describe healthcare-seeking behaviors for respiratory illnesses in one rural and one urban community in Western Java, and to explore the factors that affect care seeking. From February 8, 2012 to March 1, 2012, a survey was conducted in 2520 households in the East Jakarta and Bogor districts to identify reported recent respiratory illnesses, as well as all hospitalizations from the previous 12-month period. We found that 4% (10% of those less than 5years) of people had respiratory disease resulting in a visit to a healthcare provider in the past 2weeks; these episodes were most commonly treated at government (33%) or private (44%) clinics. Forty-five people (0.4% of those surveyed) had respiratory hospitalizations in the past year, and just over half of these (24/45, 53%) occurred at a public hospital. Public health programs targeting respiratory disease in this region should account for care at private hospitals and clinics, as well as illnesses that are treated at home, in order to capture the true burden of illness in these communities.

    On May 29, 2006, mud and gases began erupting unexpectedly from a vent 150 meters away from a hydrocarbon exploration well near Sidoarjo, East Java, Indonesia. The eruption, called the LUSI (Lumpur 'mud'-Sidoarjo) mud volcano, has continued since then at rates as high as 160,000 m3 per day. At the request of the United States Department of State, the U.S. Geological Survey (USGS) has been providing technical assistance to the Indonesian Government on the geological and geochemical aspects of the mud eruption. This report presents initial characterization results of a sample of the mud collected on September 22, 2007, as well as inerpretive findings based on the analytical results. The focus is on characteristics of the mud sample (including the solid and water components of the mud) that may be of potential environmental or human health concern. Characteristics that provide insights into the possible origins of the mud and its contained solids and waters have also been evaluated.

    In order to work towards further reduction of vitamin A deficiency in central Java, Indonesia, a social marketing campaign promoting eggs and dark-green leafy vegetables was initiated in March 1996. The nutritional surveillance system (December 1995-December 1996) found the following. The campaign's messages were well noticed. Consumption of at least one egg in the past week increased from 80% to 92% in mothers and from 78% to 92% in children 12-36 months old. It increased in all socio-economic groups and was independent of ownership of chickens. Most eggs had been purchased. The quantity of vegetables prepared increased from 93 to 111 g/person daily and most was purchased. Vitamin A intake increased from 335 to 371 RE/d for mothers and from 130 to 160 RE/d for children. Serum retinol levels increased after the start of the campaign, and were related to egg consumption and vitamin A intake. Because 1. data were collected in such a way that respondents were not aware of the link between data collected and the campaign, and 2. vitamin A status increased and was related to increased consumption of eggs and vitamin A intake, we conclude that the social marketing campaign was successful.

    Dengue is a major mosquito-borne viral disease and an important public health problem. Identifying which factors are important determinants in the risk of dengue infection is critical in supporting and guiding preventive measures. In South-East Asia, half of all reported fatal infections are recorded in Indonesia, yet little is known about the epidemiology of dengue in this country. Hospital-reported dengue cases in Banyumas regency, Central Java were examined to build Bayesian spatial and spatio-temporal models assessing the influence of climatic, demographic and socio-economic factors on the risk of dengue infection. A socio-economic factor linking employment type and economic status was the most influential on the risk of dengue infection in the Regency. Other factors such as access to healthcare facilities and night-time temperature were also found to be associated with higher risk of reported dengue infection but had limited explanatory power. Our data suggest that dengue infections are triggered by indoor transmission events linked to socio-economic factors (employment type, economic status). Preventive measures in this area should therefore target also specific environments such as schools and work areas to attempt and reduce dengue burden in this community. Although our analysis did not account for factors such as variations in immunity which need further investigation, this study can advise preventive measures in areas with similar patterns of reported dengue cases and environment.

    The Integrated Model of Change has successfully explained the behavior change process. Cigarette smoking is a social phenomenon, which needs to be understood for devising effective preventive strategies. The study aims to apply the Integrated Model of Change to determine predictive factors of cigarette smoking behavior among school adolescents in Indonesia. A school-based cross-sectional study was designed to collect data in Banten, Indonesia. A total of 698 students from eight high schools were recruited by multi-stage cluster sampling. The association between cigarette smoking and the independent variables was examined by multiple logistic regressions. The majority of respondents (86.4%) were between the ages of 15 and 17 years (Mean=16.4 years; SD=1.01). Approximately half (48.8%) of the students ever tried a cigarette while 29.6% were current smokers. Curiosity was reported as the main reason for experimenting with cigarettes (32%). The significant factors regarding current cigarette smoking were attitude [adjusted odds ratio (AOR)=2.68], social norms (AOR=12.80), self-efficacy (AOR=15.85), and accessibility (AOR=4.39). The study revealed social influence and self-efficacy that were strongly associated with cigarette smoking can help authorities in guiding possible intervention programs for school adolescents.

    Full Text Available This article reflects on these questions as they relate to the Sundanese-speaking population of western Java, Indonesia's second largest ethnic group. "Sundaneseness" is to a great extent defined by vernacular usage of the local language, basa Sunda, which is related to but distinct from Javanese, Indonesian, and the other Austronesian languages of the region. Speakers of Sundanese currently number more than 30 million, rivaling the populations of such countries as Canada, Morocco, and Kenya (and twice the population of their erstwhile colonizers, the Netherlands, yet Western scholarly literature on "Java" has paid them scant attention. Ethnographic studies of the island's Muslim communities, from Geertz's Religion of Java to Woodward's Islam in Java, have been similarly skewed towards the dominant Javanese ethno linguistic group inhabiting central and eastern Java.Copyright (c 2014 by SDI.

    Full Text Available This paper reports our effort to asses wind energy potentials for three locations in East Java. We used wind speed data over a period of almost 3 years, i.e. in period of June 2006 – August 2008. Data were taken from direct measurement in locations in East Java Province, i.e. Sampang (Madura, Juanda (Surabaya, and Sawahan (Nganjuk. The short-term of wind speed mean in monthly signifies to wind-speed value ”which parallels to the wind turbine power curve value” were used to estimate the annual energy output for a 1 MW installed capacity wind farm on the each site 100 of 10kW rated wind turbines were used in the analysis. The short term of wind speed mean at Surabaya and Nganjuk were 2.34, 3.03 and 1.97 m/s at 2 m Above Ground Level (AGL, respectively. In both locations, wind speeds were observed during the day time between 04.00 and 18.00 and relatively smaller ones between 19.00 and 03.00 period. Meanwhile, in Sampang (Madura the higher wind speeds were observed between 20.00 and 06.00, and relatively smaller between 07.00 and 19.00 period. The 1 MW windfarm at Sampang, Surabaya and Nganjuk can produce 1.284; 1.199 and 1.008 MWh of electricity yearly, taking into consideration of the temperature adjustment coefficien of about 6 %. The plant capacity factor at Sampang, Surabaya and Nganjuk were found to be 30.02 %, 30.00 % and 30.01 % respectively. Additionally, it is noticed that these site can contribute to the avoidance of 0.904; 0.846 and 0.709 tons/year of CO2 equivalent Green House Gases (GHG from entering into the local atmosphere, thus creating a clean and healthy athmosphere for local inhabitants.

The treatments consisted of two K fertilizer sources (potassium chloride-KCl and potassium sulphate-K2SO4, two K rates (150 and 250 kg K2O ha-1, and three application methods (single, split, and split combined with foliar application, were arranged in a randomized complete block design with four replications. In the single application treatment, K was applied at planting, while in the split application treatment the K was applied half rate at planting and the rest at 6 weeks after planting (WAP. In the split combined with foliar application treatment, the K fertilizer was applied half rate at planting, a quarter rate at 6 WAP and another quarter rate by foliar spraying at 7, 8 and 9 WAP. The results showed that plant height was not significantly affected by the treatment (P >0.05. However, the sources and application methods of K fertilizer affected canopy cover, crop cover weeks (CCW, tuber dry weight (DW, and total plant DW at 10 WAP. Potatoes supplied with K2SO4 either in split or split combined with foliar application had significantly higher percent canopy cover, CCW, tuber DW, and total plant DW than those supplied with K fertilizer in single application. Potatoes supplied with K2SO4 had a higher tuber yield compared to those fertilized with KCl, especially under split or split combined with foliar application. To attain the same level of tuber yield as in the split combined with foliar application method, the rate of K2SO4 should be increased from 150 to 250 kg K2O ha-1 when using single application. It is therefore suggested that K2SO4 for potatoes should be used in split application combined with foliar application.

    Study to address positive impact of revegetation program to increasing diversity of bird had been conducted in coastal area of Socorejo, Tuban - Indonesia. Field observation conducted during April 2011 (representing pre-revegetation period), April 2015 and May 2016 (representing post-revegetation period). A belt transect (500 meter long and 50 meter width) was used to survey the abundance and species composition of birds community. In general, we identified at least 51 bird species from three observation times. From 2011 to 2016, the numbers of the birds identified are 23, 37 and 37 species; while the Shannon-Wiener diversity indices (H') are 1.865, 2.071 and 2.957, respectively. In addition, there are 11 national or internationally protected species, 3 Indonesian endemic species and 12 migratory species occurred in the area. As a conclusion, the coastal revegetation program provides positive impact by generating habitat function for bird community.

    We focus in this paper on the processes and consequences of an unusual volcanic eruption at Kelut volcano, East Java. In November 2007, after two months of worrying precursor signs, Kelut volcano erupted. But neither explosions nor the usual hazards observed during the historic eruptions happened (e.g. ash falls, volcanic bombs and pyroclastic flows). Instead of an explosive eruption, the 2007 eruption was extrusive. Given than such an eruption could not be predicted, the authorities had to manage a new situation. We conducted interviews with nine stakeholders of the crisis management team, and undertook a questionnaire-based survey in the settlement nearest to the crater, in order to understand how the authorities managed the crisis, and how people reacted. Inquiries and questionnaires were carried out shortly after the end of the evacuation process, when the volcano was still under surveillance for fear of an explosive phase. The results display a real gap in what it takes to manage a crisis or live through a crisis. This suggests that the "unusual" eruption pattern of Kelut volcano was not the only factor of the misunderstanding between the authorities and the population. These problems stem from more structural causes such as the lack of communication and information when there is a need to adapt to a new scenario. In such a situation, the inability of the crisis management system to take decisions underscored the intrinsic vulnerability of the population despite a hierarchical and strategic top-down crisis management approach.

    Ambient noise tomography is relatively a new method for imaging the shallow structure of the Earth subsurface. We presents the application of this method to produce a Rayleigh wave group velocity maps around the Merapi Volcano, Central Java. Rayleigh waves group velocity maps were reconstructed from the cross-correlation of ambient noise recorded by the DOMERAPI array which consists 43 broadband seismometers. In the processing stage, we first filtered the observation data to separatethe noise from the signal that dominated by the strong volcanic activities. Next, we cross-correlate the filtered data and stack to obtain the Green’s function for all possible station pairs. Then we carefully picked the peak of each Green’s function to estimate the dispersion trend and appliedMultiple Filter Technique to obtain the dispersion curve. Inter-station group velocity curvesare inverted to produceRayleigh wave group velocity maps for periods 1 to 10 s. The resulted Rayleigh group velocity maps show the interesting features around the Merapi Volcano which generally agree with the previous studies.

    We use local earthquake data observed by the amphibious, temporary seismic MERAMEX array to derive spatial variations of seismic attenuation (Qp) in the crust and upper mantle beneath Central Java. The path-averaged attenuation values (t∗) of a high quality subset of 84 local earthquakes were calculated by a spectral inversion technique. These 1929 t∗-values inverted by a least-squares tomographic inversion yield the 3D distribution of the specific attenuation (Qp). Analysis of the model resolution matrix and synthetic recovery tests were used to investigate the confidence of the Qp-model. We notice a prominent zone of increased attenuation beneath and north of the modern volcanic arc at depths down to 15 km. Most of this anomaly seems to be related to the Eocene-Miocene Kendeng Basin (mainly in the eastern part of the study area). Enhanced attenuation is also found in the upper crust in the direct vicinity of recent volcanoes pointing towards zones of partial melts, presence of fluids and increased temperatures in the middle to upper crust. The middle and lower crust seems not to be associated with strong heating and the presence of melts throughout the arc. Enhanced attenuation above the subducting slab beneath the marine forearc seems to be due to the presence of fluids.

    Ambient noise tomography is relatively a new method for imaging the shallow structure of the Earth subsurface. We presents the application of this method to produce a Rayleigh wave group velocity maps around the Merapi Volcano, Central Java. Rayleigh waves group velocity maps were reconstructed from the cross-correlation of ambient noise recorded by the DOMERAPI array which consists 43 broadband seismometers. In the processing stage, we first filtered the observation data to separatethe noise from the signal that dominated by the strong volcanic activities. Next, we cross-correlate the filtered data and stack to obtain the Green's function for all possible station pairs. Then we carefully picked the peak of each Green's function to estimate the dispersion trend and appliedMultiple Filter Technique to obtain the dispersion curve. Inter-station group velocity curvesare inverted to produceRayleigh wave group velocity maps for periods 1 to 10 s.

    An estuary area is a typical ecosystem where a vast array of fish breed to enlarge populations. These regions are made productive by organic material in the form of foodstuff, while receiving sunlight sufficient enough to illuminate the brackish waters. These zones must be protected due to their fertile waters and surrounding fertile land. Estuary areas are threatened by nearby landfill and waste debris along and upstream of the river, which consequently contaminate the estuary zone. Socio-economic conditions of the community also affect the sustainability of the estuary. In this case, the Socio-Economic Spatial Model, based on Geographical Information System (GIS) and trade off analysis, were used to elaborate the ecosystem sustainability in the Cimandiri estuary, West Java. This research also uses the temporal analysis of land use change upstream and monitors the community activity around the estuary. The research showed a change in the spatial and temporal land use consequently altering the watershed and the socio-economic analysis showed the community use of the estuary as unsustainable for the region and ecosystems within.

    Phytoplankton plays an important role as primary producer and denotes the fertility of territorial waters. Samples were taken from a fishpond and estuary on August 27th, 2016 at Subang, West Java. The purpose of this research was to understand how the distribution and community structure of phytoplankton on fishpond and estuary differ. The result showed that phytoplankton found were composed by 6 classes: Cyanophyceae, Euglenophyceae, Chlorophyceae, Bacillariophyceae, Dinophyceae, and Xanthophyceae. Dinophyceae was found only in estuary, and Xanthophyceae was found only in the fishpond. Index of diversity (H') in the estuary was 2.41 and value of evenness (E) was 0.73. In fishpond, the value of H' was 1.63 and the value of E was 0.59, which shows no significance difference between the two locations. However, there was a difference between the number of Bacillariophyceae and Euglenophyceae found in both locations, and the difference between classes of phytoplankton found shows there might be some relations to the environmental parameters.

    Baribis fault is one of West Java fault zones which is an active fault. In modern era, the existence of fault zone can be observed by gravity anomaly. Baribis fault zone has not yet been measured by gravity directly. Based on this reason, satellite data supported this research. Data used on this research are GPS satellite data downloaded from TOPEX. The purpose of this research is to determine the type and strike of Baribis fault. The scope of this research is Baribis fault zone which lies on 6.50o - 7.50o S and 107.50o - 108.80o E. It consists of 5146 points which one point to another is separated by 1 minute meridian. The method used in this research is the Second Vertical Derivative (SVD) of gravity anomaly. The Second Vertical Derivative of gravity anomaly show as the amplitude of gravity anomaly caused by fault structure which appears as residual anomaly. The zero value of residual gravity anomaly indicates that the contact boundary of fault plane. Second Vertical Derivative method of gravity was applied for identifying Baribis fault. The result of this research shows that Baribis fault has a thrust mechanism. It has a lineament strike varies from 107o to 127o. This result agrees with focal mechanism data of earthquakes occurring on this region based on Global CMT catalogue.

    2016-02-01

    We analyzed teleseismic receiver functions from five broadband stations to determine the crustal thickness and Vp/vs ratios in the southern part of west Java. We observed that the study area is characterized by crustal thickness around 31-37 km with Vp/Vs varying between 1.66 and 1.87. We suggest that lower values of Vp/Vs obtained in some stations indicate more felsic crustal composition. The mid-crust low velocity zone is observed beneath a seismic station located near the volcanic zones with high values of Vp/Vs ratio suggesting the presence of partial melt due to geothermal activities in the upper mantle. Furthermore, a seismic station located near the active fault zone also has high Vp/Vs ratio, which may indicate the presence of fluid filled fracture zone. However, this station exhibits complicated receiver functions, thus it needs further research involving a larger dataset with good backazimuth coverage of the teleseismic data to resolve this issue.

    Full Text Available A detailed description of wood anatomy is essential for assessing the use of a wood species for processing , and also beneficial for the identification of wood samples. Computerized keys are available that allow the identification of wood samples until the genus level; however, it is not easy to use these keys to identif y unknown species. Therefore, a database of anatomical characteristics and the computerized keys need to be completed up to species level. As the relevance, this study has examined the wood anatomical properties of the five corresponding tree species originated from Cianjur, West Java, which are commercially potential for their exploitation, i.e Castanopsis acuminatissima ADC. (Fagaceae; Castanopsistungurrut ADC. (Fagaceae; Cinnamomum inners Reinw. ex Blume (Lauraceae; Ficus nervosa Heyne (Moraceae and Horsfieldia glabra Warb. (Myristicaceae. Expectedly the results would be beneficial for wood identification purposes and evaluation for other possible uses. Obser vations on anatomical structures covered macroscopic and microscopic characteristics were carried out through the sectioned and macerated wood samples. The obser ved characteristics of the anatomical features were defined conforming to the IAWA List of Microscopic Features for Hardwood  Identification.  Based on the scrutiny on those obser ved characteristics and linked to the fiber quality, it was judged that the fiber in all the five wood species could be classified as class I for pulp and paper processing.

    Full Text Available Mariculture (marine aquaculture has been intensified and has created essential employment opportunities over the last two-decades in Indonesia, as well as many other countries in the world. This development has also augmented environmental concerns and questions about possible environmental impacts. Considerable amounts of nutrient waste in dissolved and particulate form were released by intensive fish faming into the environment through feed excess, soluble fish excretion and faeces production. One of the first steps to avoid the dangerous environmental impacts is careful site selection. Hence, before the implementation of fish farming mariculture activities, appropriate site conditions for culturing the species should be selected in order to minimize environmental impacts arising from the farming activities (sustainability as well as to guarantee adequate conditions from the operational point of view (suitability. The paper focuses on the development of a Decision Support System (DSS as a tool for the decision maker in coastal zone management and mariculture for the appropriate selection of mariculture site location. Extensive use of GIS as part of the Decision Support System was deployed in this study. The DSS is based on physical, chemical and sediment criteria as well as on data of conflicting coastal use. The GIS analysis results in a map indicating the suitable areas for the improved method of offshore cage mariculture. In this study, emphasis was placed on finfish species, however the methods and results may be employed for other species as well following some modifications. The DSS was applied for the western part of Java Sea, Indonesia. The data were acquired from direct field measurement, numerical modelling and existing information from particular agencies. Numerical modelling was used to obtain spatial and temporal distributions of hydrodynamic parameters (i.e. current velocities and water levels. The Delft3D modelling system (Delft

    2016-11-01

    This study examines the fluvial readjustment of a Javanese river impacted by the major eruption of the Merapi volcano (Indonesia) in October and November 2010. The basin of the Opak River, located on the southern flank of the Merapi, was subject to substantial sediment input related to massive pyroclastic deposits that were remobilized by numerous lahars during the year after the eruption. Two study sites were equipped in order to evaluate the morphodynamic evolution of the riverbed of the Opak River. Topographic surveys, bedload particle marking, and suspended sediment sampling revealed an important sediment mobilization during efficient flash floods. Surprisingly, no bed aggradation related to the progradation of a sediment wave was observed. Two years after the eruptive event, marked bed incision was observed. The Opak River readjustment differs from that of other fluvial systems affected by massive eruptions in two ways. Firstly, local population extracted the sand and blocks injected by the eruption as they represent a valuable economic resource. Secondly, several dams trapped the major part of the sediment load remobilized by lahars.

    2003-04-01

    Papandayan volcano (2665 m a.s.l) is located in the western part of the island of Java. The last magmatic eruption of this volcano occurred in 1772. At that time, the NE sector of the volcano collapsed, producing a large avalanche of debris and creating a horseshoe shaped crater. The most recent activity of Papandayan occurred in November 2002 when the volcano erupted ash clouds to altitudes of about 5 km. Before this event, the volcano was in a state of passive degassing with solfatara, sulfur-pools and hot springs. Since 1994, the geochemistry of these hot springs is monitored. These springs are acid sulfate-chloride waters with pH between 1.5 and 2.5. Sulfur isotopic composition (delta 34: 8-14.5 per mil) clearly suggest the injection of magmatic volatiles (SO2) to the hydrothermal system present at depth.A survey of diffuse CO2 degassing using the accumulation chamber method was performed in August 2001. 420 uniformly distributed points were measured in the main crater (Kawah Emas) covering an area of 58,000 m2. At least, two distinct populations of values are present. Diffuse CO2 degassing show a wide range of values from background values up to fluxes as high as 6,190 g/m2/day. The total degassing flux of CO2 estimated for this area is 7,410 t/year. This survey was completed in September 2002 with measurements of soil CO2 concentrations (at 50 cm depth). Concentrations as high as 30 vol. % were measured in some areas and clearly revealed the position of active faults on the crater floor. Kelud volcano (1650 m a.s.l.) is located in the eastern part of Java island and contains a crater lake. The Kelud historical eruption consisted mainly of pyroclastic flow and surges. Kelud volcano is known for its devastating lahars and a system of drainage was build in 1920 in order to keep the volume of the lake to 2 million m3.The last magmatic eruption occurred in 1990. Periodical geochemical surveys were carried out at the lake waters since 1993 to understand the

    2017-09-01

    Full Text Available The change of land use in Mt. Muria area Central Java has been resulting in the significant sheet erosion of upstream watershed around Mt. Muria, followed by considerably high sedimentation on rivers downstream that lead to the reduction of cross sections of the rivers including Logung River. Such situation has been contributing the condition that downstream of Logung River is very potential to experience over flow and inundation to its surrounding area. An idea of constructing the Logung Dam was introduced in 1986 that aimed at reducing the aforementioned inundation. Besides, the development of Logung Dam was also aimed at fulfilling both irrigation and non-irrigation water demand. This paper presents the results of the analysis of the water availability and flood control performance of the Logung Dam. The dependable flow was analyzed by applying the National Rural Electric Cooperative Association (NRECA method in order to determine the low flow characteristics, whereas the identification of the high flow characteristics was carried out by using the Synthetic Unit Hydrograph (SUH methods, i.e., the GAMA I and Nakayasu modeling approach. At a certain reservoir characteristic and a defined geometry of spillway, several reservoir routing simulations were carried out on both dependable flows and high flows. Results of the reservoir routing showed the promising water availability of the Logung Dam to fulfill water demand for both irrigation and non-irrigation, whereas the reservoir routing could reduce the probable maximum flood from QPMF from 1,031 m3/s to approximately 950 m3/s or damping efficiency at 7.86%. Further analysis suggests necessary operation and maintenance of Logung Dam to sustain its function and to mitigate possible problems related to reservoir sedimentation.

    Full Text Available Five farmer groups in Lawang, Malang Regency, East Java Provinces, established organic agricultural practices almost two decades. They were visited frequently for farmer benchmarking activities; therefore they had planned to develop agroedutourism. The aims of this research were to identify potential organic farming activities as agroedutourism attractions as well as farmer ecopreneurship, to find out the existing agroedutourism facilities profile and to propose some strategies for further sustainable development. The data were gathered by interviewing key person of each farmer group in Lawang. Their agroedutourism profiles compared with a developed local agro-tourism using gap analysis. Farmer groups offered some distinct attractions and become their strengths such as out door activities in the organic perfumed and pigmented rice field, fruits and vegetable garden, zero waste management, biological pest control and healthy agricultural products. Establishment of this agroedutourism would be advantageous to lesson sharing among farmers and students, to be ecopreneur activity shown by an effective market system, to show real benefits of healthy agro-ecosystem and its products, as well as to show promising green business or ecopreneurship. Collaboration among them would improve available attractions and length of visit. Moreover, the results showed that 80% of farmer groups were visited regularly 5-10 times per month by potential visitors such as other farmer groups, house wives, staffs of agricultural departments and students. All farmer groups planned to develop agroedutourism; however the policy was only issued by 60% of farmer groups. Most of farmer groups showed a high variability in providing edutourism tours and guides. For sustainable development, farmer groups should provide more interesting attractions and facilities, develop their human resource, net working, and public promotion.

  20. Morphology and sedimentology of Halimeda bioherms from the eastern Java Sea (Indonesia)

    Roberts, H. H.; Aharon, P.; Phipps, C. V.

    1988-03-01

    Halimeda bioherms, occurring primarily along the western and southern margins of Kalukalukuang Bank in the eastern Java Sea, display a wide variety of thicknesses and shapes. In general, high-frequency forms of the northern bank are replaced by thicker and lower frequency forms along the deeper southern margin. Sidescan sonar data suggest aperiodic reworking of shallow bioherm crests of the northern bank into features suggestive of bedforms. These features are not associated with deeper bioherms of the southern bank. Cores from the bioherms indicate that they consist mostly of disarticulated Halimeda plates set in a lime mud matrix composed largely of Halimeda fragments and foraminifera tests. Carbon-14 dating shows that, with exception of some deep southern bank examples, bioherms are actively accreting. Results of mineralogy and elemental chemistry on piston core PC-12 suggest cyclic variations in Mg-calcite (cement in Halimeda utricles), which may be related to periodic excursions of cold Pacific throughflow water onto the bank. Composition of the Mg-calcite (8.6 mole-%) suggests a temperature of formation of about 22 °C, which is 7 °C below average surface water temperatures. The carbon and oxygen isotope compositions of both aragonite and Mg-calcite phases are remarkably homogeneous, but were inconclusive with regard to the cold-water intrusion hypothesis. However, a lack of reef-building corals below a depth of ˜15 m, abundance of Halimeda bioherms on the western margin of K-Bank, where upwelling is predicted, extensive boring of sedimentary particles by endolithic boring algae, and high nutrient values of water at the thermocline (50 70 m deep) all support the incursion of cold, nutrient-rich water onto the bank. Upwelling and nutrient overloading are suggested as explanations for remarkable algal growth at the expense of reef-building corals.

    The tsunami source of the July 2006 West Java Earthquake (8:19:28, 17 July, 2006, UTC) were estimated from the tsunami waveforms recorded on tide gauges around the Indian Ocean. The inversion reveals that the tsunami source was about 200 km long. The largest slip, about 2.5 m, was located about 150 km east of the epicenter. Most of the slip occurred on shallow parts of the fault, indicating that this earthquake shares the same characteristics with "tsunami earthquakes" that generates abnormally large tsunamis than expected from seismic waves. The slip distribution yields a total seismic moment of 7.0 × 1020 Nm (Mw = 7.8). The July earthquake generated a tsunami that left more than 800 persons dead or missing in western Java. The long duration and slow rupture velocity inferred from seismic waves [Ammon et al., preprint], and slight ground shaking would indicate that this earthquake was a "tsunami earthquakes." The tsunami was instrumentally recorded and provides us an opportunity to analyze tsunami waveforms to estimate the tsunami source. We use the tide gauge data collected by Global Sea Level Observing System (GLOSS) and those operated by Australian Bureau of Meteorology (BoM). Since the phase velocity of shallow- water waves depends only on the water depth, accurate bathymetric data is essential for the tsunami numerical computation. We used the GEBCO data, gridded bathymetry data digitized from contour map. We first estimate the tsunami source area from the observed tsunami travel times, by calculating the initial wavefronts through back projection of tsunamis from tide gauge stations toward the source. The tsunami travel times poorly constrain the source area, probably because shallow bathymetry near these gauges is not well known. We then perform tsunami waveform inversion by dividing the source area into 10 subfaults. Tsunami propagation from each subfault to stations or Greens functions were calculated for a rise time of 1 min, numerically solving the

    The realization of local earthquake tomography is usually conducted by removing distant events outside the study region, because these events may increase errors. In this study, tomographic inversion has been conducted using the travel time data of local and regional events in order to improve the structural resolution, especially for deep structures. We used the local MERapi Amphibious EXperiments (MERAMEX) data catalog that consists of 292 events from May to October 2004. The additional new data of regional events in the Java region were taken from the Meteorological, Climatological, and Geophysical Agency (MCGA) of Indonesia, which consist of 882 events, having at least 10 recording phases at each seismographic station from April 2009 to February 2011. We have conducted joint inversions of the combined data sets using double-difference tomography to invert for velocity structures and to conduct hypocenter relocation simultaneously. The checkerboard test results of Vp and Vs structures demonstrate a significantly improved spatial resolution from the shallow crust down to a depth of 165 km. Our tomographic inversions reveal a low velocity anomaly beneath the Lawu - Merapi zone, which is consistent with the results from previous studies. A strong velocity anomaly zone with low Vp, low Vs and low Vp/Vs is also identified between Cilacap and Banyumas. We interpret this anomaly as a fluid content material with large aspect ratio or sediment layer. This anomaly zone is in a good agreement with the existence of a large dome containing sediment in this area as proposed by previous geological studies. A low velocity anomaly zone is also detected in Kebumen, where it may be related to the extensional oceanic basin toward the land.

    Full Text Available The upstream Lesti watershed is one of the major watersheds of East Java in Indonesia, covering about 38093 hectares. Although there are enough water resources to meet current demands in the basin, many challenges including high spatial and temporal variability in precipitation from year to year exist. It is essential to understand how the climatic condition affects Lesti River stream flow in each sub basin. This study investigated the applicability of using the Soil and Water Assessment Tool (SWAT with the incorporation of groundwater recharge prediction in stream flow simulation in the upstream Lesti watershed. Four observation wells in the upstream Lesti watershed were used to evaluate the seasonal and annual variations in the water level and estimate the groundwater recharge in the deep aquifer. The results show that annual water level rise was within the 2800 - 5700 mm range in 2007, 3900 - 4700 mm in 2008, 3200 - 5100 mm in 2009, and 2800 - 4600 mm in 2010. Based on the specific yield and the measured water level rise, the area-weighted groundwater predictions at the watershed outlet are 736, 820.9, 786.7, 306.4 mm in 2007, 2008, 2009, and 2010, respectively. The consistency test reveals that the R-square statistical value is greater than 0.7, and the DV (% ranged from 32 - 55.3% in 2007 - 2010. Overall, the SWAT model performs better in the wet season flow simulation than the dry season. It is suggested that the SWAT model needs to be improved for stream flow simulation in tropical regions.

    We conducted an operational research study involving backyard and semicommercial farms on Java Island, Indonesia, between April 2008 and September 2009 to evaluate the effectiveness of two preventive mass vaccination strategies against highly pathogenic avian influenza (HPAI). One regimen used Legok 2003 H5N1 vaccine, while the other used both Legok 2003 H5N1 and HB1 Newcastle disease (ND) vaccine. A total of 16 districts were involved in the study. The sample size was estimated using a formal power calculation technique that assumed a detectable effect of treatment as a 50% reduction in the baseline number of HPAI-compatible outbreaks. Within each district, candidate treatment blocks with village poultry populations ranging from 80 000 to 120 000 were created along subdistrict boundary lines. Subsequently, four of these blocks were randomly selected and assigned one treatment from a list that comprised control, vaccination against HPAI, vaccination against HPAI + ND. Four rounds of vaccination were administered at quarterly intervals beginning in July 2008. A vaccination campaign involved vaccinating 100 000 birds in a treatment block, followed by another 100 000 vaccinations 3 weeks later as a booster dose. Data on disease incidence and vaccination coverage were also collected at quarterly intervals using participatory epidemiological techniques. Compared with the unvaccinated (control) group, the incidence of HPAI-compatible events declined by 32% (P = 0.24) in the HPAI-vaccinated group and by 73% (P = 0.00) in the HPAI- and ND-vaccinated group. The effect of treatment did not vary with time or district. Similarly, an analysis of secondary data from the participatory disease and response (PDSR) database revealed that the incidence of HPAI declined by 12% in the HPAI-vaccinated group and by 24% in the HPAI + ND-vaccinated group. The results suggest that the HPAI + ND vaccination significantly reduced the incidence of HPAI-compatible events in mixed populations of

    The crater lake of Kawah Ijen volcano, East Java, Indonesia, has displayed large and rapid changes in temperature at point locations during periods of unrest, but measurement techniques employed to date have not resolved how the lake's thermal regime has evolved over both space and time. We applied a novel approach for mapping and monitoring variations in crater lake apparent surface ("skin") temperatures at high spatial (˜32 cm) and temporal (every 2 min) resolution at Kawah Ijen on 18 September 2014. We used a ground-based FLIR T650sc camera with digital and thermal infrared (TIR) sensors from the crater rim to collect (1) a set of visible imagery around the crater during the daytime and (2) a time series of co-located visible and TIR imagery at one location from pre-dawn to daytime. We processed daytime visible imagery with the Structure-from-Motion photogrammetric method to create a digital elevation model onto which the time series of TIR imagery was orthorectified and georeferenced. Lake apparent skin temperatures typically ranged from ˜21 to 33 °C. At two locations, apparent skin temperatures were ˜4 and 7 °C less than in situ lake temperature measurements at 1.5 and 5-m depth, respectively. These differences, as well as the large spatio-temporal variations observed in skin temperatures, were likely largely associated with atmospheric effects such as the evaporative cooling of the lake surface and infrared absorption by water vapor and SO2. Calculations based on orthorectified TIR imagery thus yielded underestimates of volcanic heat fluxes into the lake, whereas volcanic heat fluxes estimated based on in situ temperature measurements (68 to 111 MW) were likely more representative of Kawah Ijen in a quiescent state. The ground-based imaging technique should provide a valuable tool to continuously monitor crater lake temperatures and contribute insight into the spatio-temporal evolution of these temperatures associated with volcanic activity.

    The Terang-Sirasun Field in the East Java Sea of Indonesia contains 1.0 trillion cubic feet (TCF) of dry gas reserves, which are made up of over 99.5% methane with {delta}{sup 13}C of -65 per thousandth and {delta}D of -185%. The methane was formed exclusively by methanogenic bacteria via the CO{sub 2} reduction pathway. The primary source sediments for the methane were identified based on bulk geochemical and absolute biomarker concentrations. Specifically, the C{sub 25} acyclic isoprenoid 2,6,10,15,19-pentamethyleicosane (PME), and related isoprenyl glyceryl ethers, which are well known markers for methanogenic archaebacteria, were used as indicators for sediment layers thought to have had the most abundant methanogen activity. Burial history analysis and precise biostratigraphic age control provided the framework for assessing the timing of hydrocarbon fill. Our findings show that methanogenic activity was highest in marine shelfal claystones (mid-outer neritic) ranging in age from 8 Ma (Late Miocene) to present. The gas is reservoired in limestones and sands of the Paciran Member, which are dated from 6.5 to 1.3 Ma (Late Miocene-Pliocene). The top seal for the present accumulation was deposited less than 0.5 Ma ago (Quarternary), although there is strong geological evidence that older seals existed. The information obtained from this field study provides evidence that large accumulations of bacterial methane do not necessarily require early entrapment of methane from freshly deposited marine sediments. Traps may be filled with bacterial gas long after the deposition of source beds, provided that the required conditions for active methanogenesis are maintained throughout this period. (author)

    Upland watershed rehabilitation programmes in Indonesia have faced increased scrutiny for not delivering the desired reductions in downstream sedimentation rates. Partly this reflects the fact that conservation measures have not been widely adopted or maintained by upland farmers, mainly for socio-economic reasons. Another potential explanation is that sediment contributions by gullying, (riparian) mass wasting and bank erosion have been seriously underestimated or even ignored. This paper presents estimates of sediment contributions by gullies, riparian mass wasting and bank erosion in the upland volcanic Konto catchment, East Java. Runoff and sediment yield from gullies were studied in two areas with contrasting soils and land use. Gullies in the Maron area (few gullies, Andic Cambisols, maize and rice cultivation on stable broad-based terraces) were related to improper drainage of trails, roads and yards. In the Binangsri area (more widespread gullying, Eutric Cambisols, onion cultivation on forward-sloping terraces), gullying was further enhanced by the practice of downslope furrowing to promote field drainage. Estimated annual sediment yields from the two areas were strikingly different at 22-26 and 50-87 Mg ha - 1 , respectively. Riparian mass wasting was estimated to contribute ca. 4% of total sediment yield at Maron and 8-19% in the main gully system at Binangsri, with the higher value in the latter case representing the effect of extreme rainfall in the latter half of the rainy season. Short-term wet season rates of gully wall retreat at Binangsri suggested a contribution by bank erosion of ca. 3% (8% including extreme events). As such, 11-27% of the annual sediment yield at Binangsri was estimated to have come from sources other than surface erosion. Substantial volumes of sediment (29-107 Mg km - 1 of river length) were also added to streams bordered by irrigated rice fields ( sawah) in non-gullied areas, mainly through the collapse of the lowermost

    Extensive areas of Halimeda bioherms similar to those described by Orme et al. (1978), Orme (1985), Davies and Marshall (1985), and Phipps et al. (1985) from Australia's Great Barrier Reef have formed on Kalukalukuang Bank (K-Bank) 50 km east of the Sunda Shelf margin in the easter Java Sea. K-Bank is an isolated limestone platform whose top slopes southward from a water depth of about 20 m at the north to about 100 m at the south (≈30 km). It occurs in a bidirectional monsoonal wind regime and a predominantly southerly flowing current from Makassar Strait. The water column around K-Bank has a well developed shallow thermocline (50 m to 150 m). K-Bank has a relatively flat top with marginal banks of suspected Pleistocene origin as interpreted from seismic relationships. A reconnaissancelevel survey grid of high-resolution seismic profiles indicates that Halimeda bioherms are restricted to the bank margins with the exception of the eastern margin. Bioherms either extend to the steep margin of the platforms or are separated from the platform edge by banks of coral and coralline algae. The morphology of the Halimeda bioherms varies from steep-sided, elongate ridges in the northern bank area, through coalescing symmetrical mounds with partly infilled valleys, to broad undulating areas similar to those described by Orme (1985) from the Great Barrier Reef. High-resolution seismic records indicate erosional episodes in the high-relief areas, an interpretation that seems to be supported by accumulation rates calculated from C14 dates of cores. Thicknesses of Halimeda accumulation above a prominent reflector considered as Pleitocene, vary from around 20 m in the north to a maximum of over 50 m in the southwest. Accumulation rates obtained from dating of two cores to-ward the north of K-Bank, average 0.294 m/100 yr for core VC4 and a maximum of 0.59 m/100 yr in a part of core PC12. Dating of material from the top 30 cm of a deep bioherm (≈100 m) in the southwest of K

    The public-private mix (PPM) strategy has strengthened tuberculosis care and control in many countries. Indonesia, a country with a high tuberculosis burden, has a low tuberculosis case detection rate (CDR), despite PPM implementation in 2003. The PPM in Indonesia involves primary healthcare centers, hospitals, and specialized chest clinics. The long-term impact of the strategy is unknown.  We aimed to explore the case detection achievements of the tuberculosis program since PPM implementation in Central Java in 2003. This retrospective cohort study covered the period 1 January 2000 to 31 December 2014. The data from tuberculosis patients treated in all health facilities in Central Java implementing directly observed treatment short-course, recorded via a standardized form, were analyzed after being validated by the Office of Health of Central Java Province. We evaluated the CDR, case notification rate, and total number of cases, using linear regression to analyze the temporal trends of those indicators in the phases of PPM implementation. The CDR increased during the initial phase (2000-2005), decreased during the mid-phase (2006-2009), and increased slightly during the late phase (2010-2014), ranging from 13 to 61.72. These trends were observed despite a steady increase in the number of participating healthcare facilities. The regression analysis showed that the CDR of referral institutions contributed the most to the total CDR of Central Java Province. Many of the smear-negative tuberculosis cases recorded at primary healthcare centers may have been smear positive; this probable misclassification could have been partially avoided if more specific and sensitive diagnostic tools were available. The CDR remains below the national target (70%). Early awareness of a negative trend in certain program indicators is important to ensure program sustainability. Careful observation of the indicator pattern will secure the long-term success of the program.

    Amphibole has been discussed to potentially represent an important phase during early chemical evolution of arc magmas, but is not commonly observed in eruptive arc rocks. Here, we present an in-depth study of metastable calcic amphibole megacrysts in basaltic andesites of Merapi volcano, Indonesia. Radiogenic Sr and Nd isotope compositions of the amphibole megacrysts overlap with the host rock range, indicating that they represent antecrysts to the host magmas rather than xenocrysts. Amphibole-based barometry suggests that the megacrysts crystallised at pressures of >500 MPa, i.e., in the mid- to lower crust beneath Merapi. Rare-earth element concentrations, in turn, require the absence of magmatic garnet in the Merapi feeding system and, therefore, place an uppermost limit for the pressure of amphibole crystallisation at ca. 800 MPa. The host magmas of the megacrysts seem to have fractionated significant amounts of amphibole and/or clinopyroxene, because of their low Dy/Yb ratios relative to the estimated compositions of the parent magmas to the megacrysts. The megacrysts' parent magmas at depth may thus have evolved by amphibole fractionation, in line with apparently coupled variations of trace element ratios in the megacrysts, such as e.g., decreasing Zr/Hf with Dy/Yb. Moreover, the Th/U ratios of the amphibole megacrysts decrease with increasing Dy/Yb and are lower than Th/U ratios in the basaltic andesite host rocks. Uranium in the megacrysts' parent magmas, therefore, may have occurred predominantly in the tetravalent state, suggesting that magmatic fO2 in the Merapi plumbing system increased from below the FMQ buffer in the mid-to-lower crust to 0.6-2.2 log units above it in the near surface environment. In addition, some of the amphibole megacrysts experienced dehydrogenation (H2 loss) and/or dehydration (H2O loss), as recorded by their variable H2O contents and D/ H and Fe3+/Fe2+ ratios, and the release of these volatile species into the shallow plumbing

    2009-12-01

    In June 2007, the US Department of State (DOS) requested assistance from the USGS to provide technical guidance and advice to the US Mission in Indonesia regarding the Lumpur Sidoarjo (LUSI) mud crisis. In May 2006, LUSI began as a mud eruption from a series of mud springs adjacent to an oil and gas exploration well being drilled near Surabaya, East Java, Indonesia. The production of mud and waters from the LUSI crater area has now continued for more than 3 years with no significant change in mud production rate (~110,000 cubic meters per day) nor in temperature of the mud (70-80 degrees C). Engineers suggest that mud production will continue at these rates for years to decades to come. Regardless of future activity at LUSI, the current mud accumulation of more than 100 million cubic meters poses a physical and environmental hazard which requires continuous monitoring and observation. The first response to the 2007 DOS request involved a site visit to Indonesia in September 2007. The result of that visit was to recommend to the Government of Indonesia (GOI) that they focus on long-term management of the mud rather than focus on the controversy as to the cause of the eruption or the debate about stopping the flow. Other recommendations from the initial 2007 technical visit included contracting for a US scientist to be co-located with engineers of the Sidoarjo Mud Management Board (BPLS) in Surabaya, East Java, to advise and consult on day-to-day developments at the site of the mud eruption. A second technical team visit by USGS scientists and an engineer from the US Army Corps of Engineers in October-November 2008 made additional recommendations on the long-term management of the mud and was followed in December by the start of a 6 month contract for the US mud adviser. From the start of activity in mid-2006 through late-2008, there was a clear sense of urgency at the US Mission in Indonesia to provide guidance and advice and included the personal intervention of

    Water shortage is a big problem for those who live in the region with unsustainable water resource like in Kidangpananjung - a village in Cililin district West Java. With elevation of 1070 m above mean sea level, Kidangpananjung stands on crest of a hill with the geographical coordinate of 113.5° BT, 6.97° LS. Based on geological survey, the outcrop which found in Kidangpananjung indicates that this region consists of pyroclastic rock such as fresh tuff and andesitic breccia. Four springs are found in the foothills with elevation of ± 1040 m above mean sea level which indicates the location of water table. To map the groundwater distribution more precisely and understand the aquifer rock more accurately, geo-electrical approach was conducted. This method is chosen based on the principle that the survey target, the water saturated rock, would give a relatively low resistivity contrast than its surrounding rocks. The target aquifer is considered as confined aquifer at 30m - 40m beneath Kidangpananjung. The data acquisition was designed with two lines of wenner-alpha arrays with 235 meters length each. Two lines of profiling were chosen in order to map the underground layer and its resistivity and thicknesses. The resistivity measurements were carefully interpreted by using least-square inversion technique by using RES2DINV program. The purpose of this research is to understand the characteristics and depth of Kidangpananjung aquifer. Therefore, it can be used to be a reference in groundwater drilling in order to improve the living of the inhabitants of Kidangpananjung

Blood samples were also taken via cocsigalis vein of AI (active and non active HF bulls at the two National AI Stations in Lembang (25 hds and Singosari (32 hds. Identification of genetic variation was by applying PCR-RFLP method. Three genotypes were identified, namely AA, AB, and BB, resulting two alleles of A and B. Results entirely showed that the frequencies of the BB HF female were very low, with the range of 0%-6% (vs AA genotype= 10%-54% and AB genotype= 46%-85%, despite of the relatively high frequency of the B allele over the A allele (23%-48% vs. 52%-77%. The low frequency of the observed BB females might be due to the limited AI active BB bulls used for services by the two national AI stations (0%-4%.

The potential of protected cultivation was higher energy productivity than open field production, indirect energy and renewable energy were the main source of energy. The ratio of output to input energy was higher in greenhouse production (0.85, 0.45 and 0.49 than open field (OF vegetable production (0.52, 0.175 and 0.186 for tomato, and chili. Financial analysis revealed higher mean net returns from greenhouse vegetable production as 7043 $/ha (922-15,299 $/ha when compared to 563 $/ha (43-1,172 $/ha from open field vegetable production. Among the greenhouse vegetables, tomato cultivation was the most profitable in terms of energy efficiency and financial productivity. Generally, reducing pest and disease in vegetable production is a main expectation from newly adopted technology. Limited land holding size of agricultural fields, high capital investment and lack of infrastructure were the constraints in improving their production through new technology. Low price of the product and lack of adequate market were also the other problems with vegetable production. Inadequate government support in term of training and financial support to farmers in certain areas make it difficult in protected cultivation technology. Capacity building of farmers, research and development on protected cultivation, manufacturing and financial sector support, supporting an efficient and adequate marketing system of protected cultivation product, and development of an agribusiness area especially for export

    Growth and survival of fishes can be influenced by temperature [1]. Variation among size like weight and length could be the preference how temperature works on growth of fishes [2]. This could be key factor in determining in production as well as market demand since people like heavy and large fishes. The main purpose of this study was to determine the effects of temperature on the growth of milkfish (Chanos Chanos) on weight and length parameters in fish farms Blanakan. This study conducted to assess the optimal temperature for the growth of fish of different sizes to optimize the culture conditions for raising milkfishes in scale cultivation in Blanakan, West Java. Milkfishes were reared in the aquaculture Blanakan ponds because they can adapt very well. The weight and length of milkfishes were measured together with water temperature. The results showed the temperature min (tmin) and max (tmax) were ranged from 29-35 °C. Based on the result, there were significant differences in mean weight (p = 0.00) between temperature with the fish reared in tmax group having the lowest mean weight (99.87±11.51 g) and fish reared in tmin group having the highest mean weight (277.17±33.76 g). Likewise, the significant differences were also observed in mean length (p = 0.00) between temperature with the fish reared in tmax group having the lowest mean length (176.50±12.50 mm) and fish reared in tmin group having the highest mean length (183.60±23.86 mm). Therefore, this paper confirmed the significant effects of temperature on the fish growth reared in aquaculture ponds. More, maintaining aquaculture to lower temperature can be considered as way to keep growth of milkfish well.

    Gunung Merapi, one of Indonesia's most active volcanoes, is characterized by long periods of dome growth and intermittent explosive pyroclastic events. Merapi currently degasses continuously through high-T fumaroles (>200°C), and erupts crystal-rich basaltic-andesite that contains a large range of igneous and calc-silicate crustal inclusions. To evaluate mechanisms that trigger explosive eruptions, we sampled lavas, inclusions (xenoliths), and gas from active fumaroles. Additionally, we established a time-integrated experiment reaction series mimicking crustal assimilation at Merapi under magmatic conditions. Merapi lava contains abundant plagioclase crystals which show complex zoning and vary in anorthite (An) content between 40 and 95 mol% across resorption surfaces. A negative correlation between An mol% and other indicators of magmatic fractionation, such as MgO and FeO, has been observed. Moreover, Sr isotope analyses of discrete zones in plagioclase yields 87Sr/86Sr values that notably exceed those of the host lavas. Zones with the highest An content also tend to show the highest radiogenic Sr values, consistent with a Ca-rich, high-87Sr/86Sr crustal contaminant. Abundant metamorphosed limestone xenoliths contain compositionally identical feldspar to the high-An population in the lavas, demonstrating that magma-crust interaction is a significant process at Merapi. Carbon isotope ratios of fumarole CO2 sampled during quiescent degassing periods form a baseline of δ13C2001-2008 = -4.1%. The notable exceptions are the 2006 values, obtained immediately after the eruption and the 6.4 magnitude Yogyakarta earthquake, which show elevated δ13C values up to -2.4%. Notably, the rise in δ13C values coincided with an increase in eruptive intensity and volcano seismicity by a factor of 3 to 5 for several weeks after the earthquake. This is consistent with addition of a late-stage, crustal volatile component added to purely mantle and slab-derived volatile sources

    Purpose Problems in health-care leadership are serious in West Sumatra, Indonesia, especially in hospitals, which are controlled locally. The purpose of this paper is to present the experience of three hospitals in balancing the conflicting demands of the national health-care system and the traditional model of leadership in the local community. Design/methodology/approach Three case studies of the hospital leadership dynamic in West Sumatra were developed from in-depth interviews with directors, senior administrators and a representative selection of employees in various professional categories. Findings An analysis of findings shows that traditional views about leadership remain strong in the community and color the expectations of hospital staff. Hospital directors, however, are bound by the modern management practices of the national system. This conflict has intensified since regional autonomy which emphasizes the local culture much more than in the past. Research limitations/implications The research was carried out in one Indonesian province and was limited to three hospitals of different types. Practical implications The findings elucidate a potential underlying cause of problems in hospital management in Indonesia and may inform culturally appropriate ways of addressing them. Originality/value The social and cultural contexts of management have not been rigorously studied in Indonesia. The relationship between local and national culture reported here likely has a similar effect in other parts of the country.

    Full Text Available Kamojang is the first geothermal field in Indonesia with a vapor dominated system reservoir. Kamojang has been exploited for over 20 years producing about 1100 tons/hour of steam which is equivalent to 140 Mwe electricity energy. This research is aimed to study the reservoir character after 20 years of exploitation and to investigate the effect of reinjection as a artificial recharge for steam input in the future and also the nature of secondary processes in the reservoir using isotope geochemistry tools. The research is conducted by natural isotopes (18O, 2H and 3H analysis of many sources of water (meteoric, cold spring, fumaroles and shallow groundwater in the surrounding of Kamojang field and also fluid reservoir to establish fluid reservoir origins and isotopic composition. Gas analysis and isotopes monitoring on the 25 production wells have been conducted every 2-3 years intervals for more than 10 years to investigate the effect of exploitation to the reservoir performance. Tritium radiotracer test with 370 GBq (10 Ci activity was conducted at the KMJ 15 reinjection well to determine qualitatively and quantitatively the flow of reinjection water to its surrounding producing well (KMJ 11, 14, 17, 18, 26, 17 and 30. Data interpretation and evaluation to determine reinjection water mass recovery and cooling prediction modeling were conducted using ICEBOX program package (TRINV and TRCOOL. Interpretation and evaluation of data concluded that reservoir fluid of Kamojang geothermal field was originated from meteoric water which infiltrated through fault structures at elevation of 1350 m –1650 m above sea level. There is no evidence that the fluid was originated from magmatic water. Reservoir fluid moved both laterally and vertically (deep fluid with lateral fluid movement from west to the east. The isotope data analysis indicated there is water entry in west-northwest reservoir boundary. Water entry gradually moved from northwest to the

    Three types of immunochromatographic test (ICT) strips were prepared for the detection of an antibody response against spherical body protein 4 (SBP-4) of Babesia bovis (bovICT), C-terminal-truncated rhoptry-associated protein 1 (rRAP1/CT17) of B. bigemina (bigICT), and the combination of both proteins (dual-ICT). The evaluation of their performance was conducted using a confirmed positive and negative serum panel for B. bovis and B. bigemina. Together with ELISA, the ICT strips were applied to determine the seroprevalence of bovine babesiosis in Western Java, Indonesia. Among 991 serum samples, 28.4%, 25.3%, and 24.5% of cattle were detected to be seropositive to B. bovis infection using ELISA, bovICT, and dual-ICT, respectively. B. bigemina seropositive was detected in 27.1%, 24.2%, and 22.8% of samples using ELISA, bigICT, and dual-ICT, respectively. The comparison of ICT strips and ELISA results using field serum samples showed good agreement with Kappa values >0.7 between all methods The application of ICT strips is preferable in the field situations where rapid diagnosis is required. Furthermore, the data showed the current seroprevalence of bovine babesiosis in Western Java, Indonesia, and efficient control strategies are needed to reduce economic losses due to the disease.

    Chemical and isotopic compositions of magmatic crystals provide important information to distinguish between deep juvenile and crustal contributions. In this work, high-resolution multicollector secondary ion mass spectrometry data reveal strong variations of δ18O values in three plagioclase crystals (800-1700 μm) from two representative basaltic andesite samples of the 2010 Merapi eruption (Central Java, Indonesia). The δ18O values (from 4.6‰ to 7.9‰) are interpreted to reflect oxygen isotope heterogeneity in the melt composition during plagioclase growth. The lowest δ18O values (4.6-6.6‰) are found in anorthite-rich cores (An82-97), whereas higher δ18O values (5.7-7.9‰) are found in anorthite-poorer zones (An33-86), typically in crystal rims. Combining these new plagioclase δ18O data with δ18O of calc-silicate crustal xenoliths erupted between 1994 and 1998, the composition of glass inclusions hosted by the anorthite-rich plagioclase (An82-92), available experimental data, and the results of thermodynamic modeling using the Magma Chamber Simulator code, we conclude that the abundant anorthite-rich cores crystallized from a mantle-derived hydrous basaltic to basaltic trachyandesite melt that recharged a deeper (200-600 MPa) magma storage zone, whereas lower anorthite zones crystallized at shallower levels (100-200 MPa). The oxygen isotope variations in the plagioclase are explained by a two-stage model of interaction of the hydrous, mafic mantle-derived magma (1) with old crustal rocks depleted in 18O due to high temperature alteration that yielded the low δ18O values in the anorthite-rich cores at deep levels (13-20 km), and later (2) with 18O-enriched carbonate material that yielded the high δ18O values in anorthite-poorer zones at shallow levels (∼4.5-9 km). Thermodynamic modeling is consistent with ∼18 wt.% assimilation of crustal calc-silicate material at 925-950 °C and 100-200 MPa by the 2010 Merapi basaltic andesite magma prior to

    The crater lake of Kawah Ijen volcano, East Java, Indonesia, has displayed large and rapid changes in temperature at point locations during periods of unrest, but measurement techniques employed to-date have not resolved how the lake’s thermal regime has evolved over both space and time. We applied a novel approach for mapping and monitoring variations in crater-lake apparent surface (“skin”) temperatures at high spatial (~32 cm) and temporal (every two minutes) resolution at Kawah Ijen on 18 September 2014. We used a ground-based FLIR T650sc camera with digital and thermal infrared (TIR) sensors from the crater rim to collect (1) a set of visible imagery around the crater during the daytime and (2) a time series of co-located visible and TIR imagery at one location from pre-dawn to daytime. We processed daytime visible imagery with the Structure-from-Motion photogrammetric method to create a digital elevation model onto which the time series of TIR imagery was orthorectified and georeferenced. Lake apparent skin temperatures typically ranged from ~21 to 33oC. At two locations, apparent skin temperatures were ~ 4 and 7 oC less than in-situ lake temperature measurements at 1.5 and 5 m depth, respectively. These differences, as well as the large spatio-temporal variations observed in skin temperatures, were likely largely associated with atmospheric effects such as evaporative cooling of the lake surface and infrared absorption by water vapor and SO2. Calculations based on orthorectified TIR imagery thus yielded underestimates of volcanic heat fluxes into the lake, whereas volcanic heat fluxes estimated based on in-situ temperature measurements (68 to 111 MW) were likely more representative of Kawah Ijen in a quiescent state. The ground-based imaging technique should provide a valuable tool to continuously monitor crater-lake temperatures and contribute insight into the spatio-temporal evolution of these temperatures associated with volcanic activity.

    Instrumental and historical records of earthquakes, supplemented by paleoeseismic constraints can help reveal the earthquake potential of an area. The Pasuruan fault is a high angle normal fault with prominent youthful scarps cutting young deltaic sediments in the north coast of East Java, Indonesia and may pose significant hazard to the densely populated region. This fault has not been considered a significant structure, and mapped as a lineament with no sense of motion. Information regarding past earthquakes along this fault is not available. The fault is well defined both in the imagery and in the field as a ~13km long, 2-50m-high scarp. Open and filled fractures and natural exposures of the south-dipping fault plane indicate normal sense of motion. We excavated two fault-perpendicular trenches across a relay ramp identified during our surface mapping. Evidence for past earthquakes (documented in both trenches) includes upward fault termination with associated fissure fills, colluvial wedges and scarp-derived debris, folding, and angular unconformities. The ages of the events are constrained by 23 radiocarbon dates on detrital charcoal. We calibrated the dates using IntCal13 and used Oxcal to build the age model of the events. Our preliminary age model indicates that since 2006±134 B.C., there has been at least five ground rupturing earthquakes along the fault. The oldest event identified in the trench however, is not well-dated. Our modeled 95th percentile ranges of the next four earlier earthquakes (and their mean) are A.D. 1762-1850 (1806), A.D. 1646-1770 (1708), A.D. 1078-1648 (1363), and A.D. 726-1092 (909), yielding a rough recurrence rate of 302±63 yrs. These new data imply that Pasuruan fault is more active than previously thought. Additional well-dated earthquakes are necessary to build a solid earthquake recurrence model. Rupture along the whole section implies a minimum earthquake magnitude of 6.3, considering 13km as the minimum surface rupture

    Padang, Indonesia, a city of some 900,000 people, half of whom live close to the coast and within a five-meter elevation above sea level, has one of the highest tsunami risks in the world due to its close offshore thrust-fault seismic hazard, flat terrain and dense population. There is a high probability that a tsunami will strike the shores of Padang, flooding half of the area of the city, within the next 30 years. If that tsunami occurred today, it is estimated that several hundred thousand people would die, as they could not reach safe ground in the ~30 minute interval between the earthquake's occurrence and the tsunami's arrival. Padang's needs have been amply demonstrated: after earthquakes in 2007, 2009, 2011 and 2012, citizens, thinking that those earthquakes might cause a tsunami, tried to evacuate in cars and motorbikes, which created traffic jams, and most could not reach safe ground in 30 minutes. Since 2008, GeoHazards International (GHI) and Stanford University have studied a range of options for improving this situation, including ways to accelerate evacuation to high ground with pedestrian bridges and widened roads, and means of "vertical" evacuation in multi-story buildings, mosques, pedestrian overpasses, and Tsunami Evacuation Parks (TEPs), which are man-made hills with recreation facilities on top. TEPs proved most practical and cost-effective for Padang, given the available budget, technology and time. The Earth Observatory Singapore (EOS) developed an agent-based model that simulates pedestrian and vehicular evacuation to assess tsunami risk and risk reduction interventions in Southeast Asia. EOS applied this model to analyze the effectiveness in Padang of TEPs over other tsunami risk management approaches in terms of evacuation times and the number of people saved. The model shows that only ~24,000 people (20% of the total population) in the northern part of Padang can reach safe ground within 30 minutes, if people evacuate using cars and

    In 2012, an ongoing outbreak of diphtheria in Indonesia was focused in the province of East Java. There was a need to assess vaccine coverage and immunity gaps in children. We conducted a cross-sectional seroprevalence and vaccine coverage survey of children 1-15 years of age in 2 districts of East Java: one of high incidence (on the island of Madura) and one of low incidence (on the mainland). From each district, we sampled 150 children (10 children per year of age). Sera and throat swabs were taken to determine immunity and carriage status. Immunity was defined as ≥0.1 international unit/mL of antibody to diphtheria toxin. A total of 297 children were selected to participate in the study. Coverage of three doses of combined vaccine for diphtheria, tetanus and pertussis was significantly lower (P Java. Immunity in high incidence districts is likely because of natural immunity acquired through exposure to toxigenic C. diphtheriae. Booster vaccines are essential for achieving protective levels of immunity.

    Geological forensic is a branch of geology which study focused on deciphering facts by using geological science method mainly for legal purposes. The use of geological forensic may be applied to fulfill legal purposes of insurance agency, compensation decisions, and also criminal cases. In this study case, geotechnical and geological engineering are used beforehand in order to identify the cause of geological phenomenon by using quantitative assessment. Soil movement disaster can be caused by several aspects. The assessment of the disaster which is rapid creeping movement of soil is conducted in a disaster case of Cigintung, West Java. The impact of disaster is significant enough to affect up to 700 families, which have to be evacuated from the disaster site, due to massive infrastructural damage. The soil of the area is categorized into clay with high plasticity and silt with high plasticity, which liquid limit (LL) is vary between 77.77% - 98.41%. Activity number (A) of each soils are is vary between 0.964 - 2.192. Based on Skempton Chart is indicating montmorillonitic and illitic soils, and also the cause of their characteristic which is swelling if it is wet and shrinking if it is dry. Therefore, by using Seed method and William & Donovan Chart, we can conclude that soil in the area is categorized into expansive soil due to its high tendency of swelling-shrinking characteristic. Chronologically, the soil movement in Cigintung is initiated with first landslide which caused surface water to infiltrate easier into porous soil and reach the expansive soil below it. The second soil movement occurred rapidly and affected almost all infrastructures in the area in 12 hours timespan, due to the change of soil bearing capacity which caused by water infiltration. The accepted soil bearing capacity (qa) with factor of stability (FS) = 3 for square-shaped shallow foundation is between 3.66 T/m2 - 9.52 T/m2, while for circle-shaped foundation is between 3.67 T/m2 - 7.53 T/m2

    Full Text Available Soils formed from volcanic materials have a high potential for agricultural development, especially for horticultural crops, tea, and pine trees. Data on the characteristics of these soils are important for the management planning. Six representative soil profiles developed on andesitic volcanic ash and tuff in Lembang area, West Java were studied to determine the soil physical, chemical, and mineralogical properties, to study the relationship between the soil properties, and to classify the soils according to the Soil Taxonomy. The results indicated that all the soils had very deep (>150 cm solum. In general, the volcanic ash soils were darker colored, more granular, more friable, less sticky and less plastic than the volcanic tuff soils. Physically, the ash soils had lower bulk density (0.44-0.73 mg m-3 and higher available water content (13-33% than the tuff soils. Bulk density decreased with increasing allophane. Chemically, the ash soils had higher pHNaF (mostly > 10, higher organic carbon (4.3-6.8% in upper horizons, higher CEC (20- 44 cmolc kg-1, and higher P retention (> 85% than the tuff soils. P retention logarithmically increased with increasing oxalate extractable Al and allophane. The sand fractions of the ash soils were dominated by hornblende, while the tuff soils were predominantly composed of opaque minerals. In the clay fractions, the ash soils were dominated by allophane, whereas the tuff soils showed high contents of gibbsite and metahalloysite. Soils developed on volcanic ash were classified as Thaptic Hapludands and Typic Melanudands, while soils formed from volcanic tuff were classified as Andic Dystrudepts. The low bulk density and friable consistency of the soils contributed to favorable soil tilth. However, high P retention and Al saturation in most soils are limiting factors for plant growth. Application of P fertilizers and liming coupled with efficient placement can be recommended to enhance P availability and

    Full Text Available The DHF prevention efforts have been continually conducted by the local health office, but some technical obstacles such as surveillance system is still very weak, and this is known as an important part in decision making process to handle the problem using evidence based information. The research objective is to obtain information on dengue endemic mapping through GIS (Geographic Information Systems to strengthen district surveillance system in district level. Most DHF cases occur in the productive age and located in urban areas with the larva-free rate is low. The direction of movement of the case are local diffusion. Karawang district is a low-lying areas prone to flooding. The rainy season occurs in late October to early May, but the rise of dengue cases at the turn of the rainy season to dry season, this indicates that the humidity in Karawang district supports the mosquito vector breeding. Foging will only kill adult mosquitoes, dengue control programs need to involve community participation and emphasized on public areas like schools and offices because a lot of dengue cases occurred in the productive age. GIS is capable of producing a map factors of risk and map of the case to allow for planning and evaluation of area-based dengue eradication program. GIS is useful in surveillance environmentally based disease, health interventions, and disease prevention strategies.

    Bandung is a densely populated and rapidly growing city, especially in the Northern Area, with many rivers flowing through it. Infrastructure development if not taken into account the geo hazard potential of the river can cause disaster to occur resulting in damages and casualties. The inundation named "Cileuncang Flood" periodically occurred in the rainy season. Landslide disaster also occurred in 2015 at Mekarsaluyu, Cimenyan and Bukit Dago Selatan. This study explores the phenomena that occurred in the region. The research objectives are to: identify geological conditions contributing to geo hazard, conduct geo hazard assessment in the area and recommend mitigation activities. Research area ranges from Sekeloa to Bojongkoneng, where there are three rivers: Cirapohan, Cidurian, and Cilimus. The research method used mixed method, field observation and desk study (secondary data). Geospatial data and geological field observation was conducted. Lithology layers coring well data was used to determine the detailed geological condition and characteristic. Research results show geological condition that can trigger disaster. There are some locations, which have disasters in the past, this occurrence is connected with geological conditions to determine the potential disaster that may occur in the future. The first site is located on the western part of the Cidurian river consisted of Cikidang Formation. Geo hazard that occurred in this zone is flood. Second site is located on the eastern part of the Cidurian river, has the presence of volcanic eruption product. Geo hazard that can potentially occur in this zone is a landslide. The city stakeholder needs to conduct structural and nonstructural mitigation activities to reduce the risks.

    Full Text Available A study on the performance of Nagrak and Kampung chicken under intensive management system was conducted in Cibadak District of Sukabumi West Java. As many as 200 hens of Nagrak and Kampung, each were placed in individual cages. The birds were given 90 g of diet daily, the diet was the mixture of layer commercial diet and ricebran at equal ratio, drinking water was given ad libitum. Artificial insemination was conducted every three days using semen collected from 20 cockerels of each local bird. Disease control was done by vaccination against Newcastle Disease and Infectious Bursal Disease. Sulfamix and antibiotics were given whenever needed. Eggs were collected twice a day, weighed and stored to be incubated or to be analyzed for their characteristics. Parameters observed were physical appearance, hen-day egg production, egg quality, egg fertility and hatchability, body weight, feed conversion and mortality. Results showed that Nagrak chicken physical appearance was different from that of Kampung chicken, yet their hen-day production were not significantly different (26.93 ± 14.10% vs 27.04 ± 16.20%. The egg characteristics of these birds (Nagrak vs Kampung were as follows: egg weight (36.29 ± 6.50 g vs 35.55 ± 5.42 g; yolk weight (16.61 ± 1.34 g vs 16.22 ± 2.11 g; albumen weight (17.31 ± 2.64 g vs 16.87 ± 1.35 g; shell weight 37 ± 0.81 g vs 2.46 ± 0.54 g; yolk color (9.62 ± 1.81 g vs 9.67 ± 1.70 g; haugh unit (83.60 ± 5.41 vs 83.45 ± 6.10; shell thickness (24.0 ± 0.83 µm vs 24.4 ± 0.67 µm, however no significant difference was found.

    The occurrence of Vibrio parahaemolyticus in raw Corbicula moltkiana Prime from Lake Singkarak and Pasar Raya Padang market and in cooked samples in West Sumatera, Indonesia, was studied. Thirteen raw and seven cooked bivalve samples were positive using CHROMAgar Vibrio medium. All 47 V parahaemolyticus isolates were positive for toxR gene but negative for trh. However, 36% (17/47) of V parahaemolyticus strains were positive for tdh gene. Antibiotic profiling showed that 76% and 38% of isolates from raw and cooked bivalves respectively were resistant to ampicillin. Using RAPD-PCR analysis, most of the strains were clustered according to their source of isolation but some of the strains from raw and cooked samples were clustered together. These results indicate that pathogenic V parahaemolyticus isolates are present in Corbicula moltkiana Prime in West Sumatera, Indonesia, suggesting that V parahaemolyticus may also be present in seafood in other regions of Indonesia.

    2016-12-13

    Poaching for the pet trade is considered one of the main threats to orangutan survival, especially to the Bornean species (Pongo pygmaeus). However, there have been few attempts to quantify the number of individuals taken from the wild or to evaluate the drivers of the trade. Most orangutan poaching is thought to be opportunistic in nature, occurring in conjunction with deforestation for large-scale agriculture. Using data from our long-term wildlife crime field investigation program collected from 2004 to 2014, we evaluated the prevalence of orangutan poaching and its spatial distribution in and around Gunung Palung National Park, in the regencies (districts) of Ketapang and Kayong Utara, West Kalimantan, Indonesia. Over the project period, investigators uncovered 145 cases of orangutans being illegally held captive for the pet trade. There was a significant correlation between the extent of oil palm and the number of cases reported from each sub-district in the landscape, supporting the widely held hypothesis that orangutan poaching is opportunistic, and we found no evidence of orangutan trading rings (i.e., international traders) targeting Gunung Palung National Park. Over the past decade, there only has been one prosecution of orangutan trading in West Kalimantan, and weak law enforcement by Indonesian authorities remains the most significant challenge in addressing wildlife trade. We offer four recommendations to address this, including that Indonesia dedicate at least $3 million more to addressing orangutan poaching and trade in Kalimantan and that the country's wildlife protection laws be revised and strengthened, with the new laws socialized to a wide audience, including government officials and all aspects of civil society. As oil palm begins to expand into Africa, this study also may help predict how this will affect gorillas, chimpanzees, and bonobos, encouraging proactive conservation action. © 2016 Wiley Periodicals, Inc.

    Full Text Available This article explores the ongoing conflict over state forest land between the local population and the State Forestry Corporation (SFC in a village in upland Central Java with regard to authority formation. It looks at how different agents draw on different sources of authority in the course of the conflict and its negotiations. The principal questions are to what kind of sources of authority villagers refer to and how the formation of authority informs the relations between the state and society in the land dispute. The article is based on 11 months of ethnographic fieldwork and focuses on the central figure of Pak Wahid who took a leading position in the forest land dispute and in mobilising peasants in the village. The article argues that in post-Suharto Java, leadership in the struggle for state forest land at the village level is embedded in the interaction of Javanese ideas of power and authority as well as administrative authority. Due to political and institutional reforms, new sources of authority could be invoked while there are no real changes in the power relations within the village or between the SFC and the villagers. ----- Dieser Artikel untersucht den anhaltenden Konflikt um staatliche Waldflächen zwischen der lokalen Bevölkerung und der State Forestry Corporation (SFC in einem Dorf im Hochland von Zentral- Java in Bezug auf die Entwicklung von Autorität. Es wird untersucht, wie sich unterschiedliche AkteurInnen im Rahmen des Konflikts und dessen Verhandlung auf unterschiedliche Bezugsquellen von Autorität beziehen. Die zentralen Forschungsfragen in diesem Zusammenhang sind, auf welche Bezugsquellen von Autorität sich DorfbewohnerInnen beziehen und wie die Entwicklung von Autorität die Beziehungen zwischen Staat und Gesellschaft im Rahmen des Landkonflikts beeinflusst. Der Artikel basiert auf einer 11-monatigen ethnografischen Feldforschung und fokussiert auf die Person von Pak Wahid, der eine Schlüsselrolle im Konflikt

    In theory, competition among species in a shared habitat results in niche separation. In the case of small recondite mammals such as shrews, little is known about their autecologies, leaving open questions regarding the degree to which closely related species co-occur and how or whether ecological niches are partitioned. The extent to which species are able to coexist may depend on the degree to which they exploit different features of their habitat, which may in turn influence our ability to recognize them as species. We explored these issues in a biodiversity hotspot, by surveying shrew (genus Crocidura) diversity on the Indonesian island of Java. We sequenced portions of nine unlinked genes in 100-117 specimens of Javan shrews and incorporated homologous data from most known Crocidura species from other parts of island South-East Asia. Current taxonomy recognizes four Crocidura species on Java, including two endemics. However, our phylogenetic, population genetic and species delimitation analyses identify five species on the island, and all are endemic to Java. While the individual ranges of these species may not overlap in their entirety, we found up to four species living syntopically and all five species co-occurring on one mountain. Differences in species' body size, use of above ground-level habitats by one species and habitat partitioning along ecological gradients may have facilitated species diversification and coexistence.

    Full Text Available Seren Taun is a ritual ceremony and celebration, which is practiced in West Java by the Sundanese. It is similar to Thanksgiving in many countries. The village Cigugur, located 3 km west of Kuningan, is the focus of the paper, because the Seren Taun celebration there has been a major event and received a lot of attention from the media, government, and scholars. Many non-Javanese traditional celebrations were repressed during the Suharto era and traditional beliefs were either also repressed or co-opted into one of the five official religions. During the post-Suharto era, the spirit of reformation has brought diversity of more than 300 ethnic groups onto the surface. With the aim to preserve and maintain the tradition of Seren Taun, but as well as to preserve the identity and collective memory of the community, Djatikusumah, chairman of PACKU, has in these recent years developed several policies, concerning traditional art performances, buildings/sites used for ceremonies, and the batik motives that were taken from woodcarvings in the Paseban hall. This paper will explore the intersection between the role of Djatikusumah as an agency and the culture industry he invented.

    To determine factors associated with the use of oral rehydration solution (ORS) in West Lombok, Indonesia, interviews were conducted among 293 mothers in six villages with a total population of 54,324. This study included mothers of children aged less than 2 years. The children had episode of diarrhoea in the past week during the 3-month survey period of June-August 1991. Questions asked included when ORS was used, how often it was used, how to make ORS, and the availability and accessibility of ORS in the community. Mothers were observed when preparing ORS. More than 66% of the mothers questioned had used oral rehydration therapy for home management of diarrhoea, either as packaged oral rehydration solution (ORS) or as salt-sugar solution (SSS). Fifty-six percent of mothers reported giving ORS and 10% reported giving SSS. Only 37% of mothers, however, were able to prepare ORS properly, and only 9% were able to prepare SSS properly. The following factors significantly increased the likelihood that a mother would use ORS: watching a demonstration of how to prepare ORS (odds ratio 6.34), availability of ORS (odds ratio 2.37), and accessibility of ORS (3.50). However, the ability to prepare ORS properly did not significantly increase the likelihood of feeding ORS. These results indicate that demonstrations of preparation of ORS and availability of ORS are necessary to increase the use of ORS for management of acute diarrhoea in West Lombok.

    Thalassemia is the most prevalent genetic blood disorder worldwide, and particularly prevalent in Indonesia. The purpose of this study was to determine the spectrum of β-thalassemia (β-thal) mutations found in the southern region of Central Java, Indonesia. The subjects of the study included 209 β-thal Javanese patients from Banyumas Residency, a southwest region of Central Java Province. DNA analysis was performed using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP), amplification refractory mutation system (ARMS), and the direct sequencing method. The results showed that 14 alleles were found in the following order: IVS-I-5 (G > C) (HBB: c.92 + 5G > C) 43.5%, codon 26 (Hb E; HBB: c.79G > A) 28.2%, IVS-I-1 (G > A) (HBB: c.92 + 1G > A) 5.0%, codon 15 (TGG > TAG) (HBB: c.47G > A) 3.8%, IVS-I-1 (G > T) (HBB: c.92 + 1G > T) 3.1%, codon 35 (-C) (HBB: c.110delC) 2.4%. The rest, including codons 41/42 (-TTCT) (HBB: c.126_129delCTTT), codons 8/9 (+G) (HBB: c.27_28insG), codon 19 (AAC > AGC) (HBB: c.59A > G), codon 17 (AAG > TAG) (HBB: c.52A > T), IVS-I-2 (T > C) (HBB: c.92 + 2T > C), codons 123/124/125 (-ACCCCACC) (HBB: c.370_378delACCCCACCA), codon 40 (-G) (HBB: c.123delG) and Cap +1 (A > C) (HBB: c.-50A > C), accounted for up to 1.0% each. The most prevalent alleles would be recommended to be used as part of β-thal screening for the Javanese, one of the major ethnic groups in the country.

    this analysis aims to explore midwives' insights into the provision of long-acting and permanent methods of contraception (LAPMs) in the selected areas of East Java and Nusa Tenggara Barat (NTB) Provinces, Indonesia. a qualitative study using in-depth interviews was conducted with 12 village midwives from 12 villages, to explore their perceptions and experiences in delivering family planning services. the study was carried out in May-June 2013, as part of the baseline assessment in the Improving Contraceptive Method Mix (ICMM) study. We interviewed 12 village midwives working in 12 villages in six study districts: Tuban, Kediri, and Lumajang Districts in East Java Province; and Lombok Barat, Lombok Timur, and Sumbawa Districts in NTB Province. an interview guideline was used in all interviews. It covered several topics, such as community perceptions of LAPMs, availability of contraception and related equipment, availability of human resources, and midwives' efforts to improve LAPM coverage. All interviews were recorded and transcribed. Content and thematic analyses were carried out by grouping and coding the information based on the identified themes and topics. according to village midwives interviewed in this study, community-level acceptance of LAPMs has increased over time; however, some still prefer using short-acting methods for a long period. The reasons include lack of awareness about the benefits and side effects of LAPMs, fear of surgical procedures, rumored consequences (for example, that LAPMs would limit women's ability to perform hard physical labor), and religious beliefs. There were several challenges reported by village midwives in delivering LAPM services, such as confusion about midwives' eligibility to provide LAPM services, lack of Contraceptive Technology Update (CTU) and counseling trainings, and shortage of supporting equipment (such as exam tables and IUD and implant insertion kits). There were several strategies implemented by village

    Accumulating evidence suggests that negative perceptions towards diabetes can limit the management and prevention of the disease. The negative perceptions towards diabetes are prevalent in many different settings, especially among rural communities. Few qualitative studies have been performed to understand how the community views diabetes and its associated risk factors. This study aimed to explore general community perceptions of diabetes and its risk factors in rural Indonesia. A total of 68 participants were recruited to 12 focus group discussions (FGDs) comprised of different age groups and sexes. The FGDs were conducted in six villages in rural Purworejo District, Central Java, Indonesia, from 2011 to 2012. All FGDs were recorded and transcribed. Qualitative content analysis was performed to describe and analyse how the rural community perceived diabetes and its risk factors. Diabetes was perceived as a visible and scary sugar disease, and the affected individuals themselves were blamed for getting the disease. Recognised as 'sugar' or 'sweet-pee' disease with terrifying effects, diabetes was believed to be a disease with no cure. The participants seemed to have an unrealistic optimism with regards to the diabetes risk factors. They believed that diabetes would not affect them, only others, and that having family members with diabetes was necessary for one to develop diabetes. Our findings demonstrate that rural communities have negative perceptions about diabetes and at the same time individuals have unrealistic optimism about their own risk factors. Understanding how such communities perceive diabetes and its risk factors is important for planning prevention strategies. Health messages need to be tailored to health-related behaviours and the local culture's concepts of diseases and risk factors.

    Variation in morphometric characters in four sand crab (Albunea symmysta) populations from four intertidal areas in Sumatra (Aceh and Bengkulu) and Java (Cilacap and Yogyakarta) were studied. Crabs collected from the four sites were measured to obtain 10 morphometric characters, i.e., carapace length (CL), carapace width (CW), ocular peduncle length and width (LOP and WOP), telson length and width (LT and WT), merus length (ML), carpus length (CaL), propodus length (PL), and dactylus length (DL). Allometric relationships were established among three morphometric characters (CW, PL, and DL) for each site, in which CL was fixed on the abscissa as a reference variable. The analysis of covariance showed that population from Yogyakarta had a greater carapace width and the Aceh population had a longer dactylus length. In terms of propodus length, the Aceh population had a longer dactylus length than the Bengkulu population. Two group populations were detected by cluster analysis with 10 morphometric characters, i.e., the Sumatra population and the Java population.

    Reassessment of travel time data from an exceptionally dense, amphibious, temporary seismic network on- and offshore Central and Eastern Java (MERAMEX) confirms the accretionary nature of the crust in this segment of the Sunda subduction zone (109.5-111.5E). Traveltime data of P- and S-waves of 244 local earthquakes were tomographically inverted, following a staggered inversion approach. The resolution of the inversion was inspected by utilizing synthetic recovery tests and analyzing the model resolution matrix. The resulting images show a highly asymmetrical crustal structure. The images can be interpreted to show a continental fragment of presumably Gondwana origin in the coastal area (east of 110E), which has been accreted to the Sundaland margin. An interlaced anomaly of high seismic velocities indicating mafic material can be interpreted to be the mantle part of the continental fragment, or part of obducted oceanic lithosphere. Lower than average crustal velocities of the Java crust are likely to reflect ophiolitic and metamorphic rocks of a subduction melange.

    Majority of people of South coast of West Java, from Sukabumi, Cianjur, Garut are fishermen. Natural conditions are very dry and the area of land for agriculture, particularly rice cultivation is minimal. So that the condition of the society is more directed to high enough levels of food insecurity. Because coastal areas tend to have a longer dry season from rainfall. Results of research conducted in the years 2013 - 2016 in the area of Pelabuhan Ratu, Cidaun (Cianjur), Coastal area of Jayanti, Ranca Buaya, Mekar Mukti, and along the coast until Pameungpeuk, Leuweung Sancang, is known that jalawure plant which grows wild at South-coast region of West Java is precisely the alternative solution to address food insecurity. The results of the starch flour is a source of carbohydrate that is high enough to be used as a substitute for rice and wheat. Another potential source of jalawure nutrition is also recommended for diabetics consumption.

    This paper aims at exploring interpretability of the panchromatic band of Landsat Enhanced Thematic Mapper Plus (ETM+) compared to the panchromatic aerial photograph in lineament and fracture trace extraction. Special interest is addressed to karst terrain where lineaments and fracture traces are expressed by aligned valleys and closed depressions. The study area is an single aerial photographic coverage in the Gunungsewu Karst, Java-Indonesia which is characterized by a lineament-controlled cone karst and labyrinth-cone karst. The result shows that the recording time of the Landsat ETM+ with respect to the shadow resulting from the sun illumination angle is the key factor in the performance of lineament and fracture traces extraction. Directional filtering and slicing techniques significantly enhance the lineament interpretability of the panchromatic band of Landsat ETM+. The two methods result in more lineaments and fracture traces which T-test affirm in 0.001 and 0.004 significant levels. Length based lineament analysis attains a better result compared to frequency based analysis.

    The purpose of this study was to compare the sensitivity and specificity of an ELISA test to detect Fasciola gigantica antigens (coproantigens) in bovine feces, with fecal egg counting and an ELISA for detecting anti-F. gigantica antibodies in serum. Monoclonal antibodies to cathepsin L were generated and used to capture this antigen in feces of infected cattle. Blood, feces, and livers were collected from 150 cattle at an abattoir in Jakarta, Indonesia, for anti-Fasciola antibodies, coproantigen detection, and F. gigantica egg and worm counts. Fluke recovery varied from 1 to 426 per host, with a mean of 32 flukes. The results showed that the sensitivity and specificity of coproantigen detecting ELISA (95 and 91%, respectively) was better than the anti-F. gigantica antibody ELISA (91 and 88%, respectively) and to fecal egg counting (87 and 100%, respectively). The coproantigen ELISA was able to detect 100% of the cattle with >15 flukes. A survey of 305 cattle in central Java over a 10-mo period validated this test in the field, demonstrating a high prevalence of fascioliasis and establishing the test as a useful diagnostic method to determine patent F. gigantica infections in cattle.

    Community-Based Mangrove Management (CBMM) is implemented with different approaches and outcomes. This study examined the effectiveness of various CBMM practices to achieve sustainable management of mangrove resources. We analyzed local mangrove resource management strategies in four coastal villages (e.g. Sriwulan, Bedono, Timbulsloko, and Surodadi) on Central Java, Indonesia. Local data on institutions, socio-economic conditions and mangrove resources utilization was collected through participatory resource mapping and interviews with 16 key actors and 500 households. The main differences in CBMM-practices that affect the outcomes in each village were the type of community participation, the level of organizational and economic assistance from external institutions, the magnitude of the rehabilitation project, the time selected for rehabilitation and the maintenance strategies applied in each village. Surodadi achieved most in terms of both efficient resource utilization and local livelihood improvement. Bedono's management strategy was most effective in extending and maintaining the rehabilitated mangrove areas but less in terms of livelihood support while the strategy applied in Timbulsloko resulted in higher resource utilization compared to Surodadi. Sriwulan failed on most criteria. This study suggests that combining the management strategies practiced in Bedono and Surodadi and adding external scientific and technological assistance, income diversification, institutional reinforcement and continuous monitoring of the functioning of local institutions can improve the CBMM performance to sustainably manage mangrove resources and improve livelihoods.

    The Tengger Caldera together with the active Mount Bromo is situated in Java, Indonesia. Though activity of Mt Bromo has been recorded since 1804, little modern petrographic and geochemical data is available. In this study we provide a detailed petrographic and stratigraphic description of the two major caldera units, i.e. the "pre-caldera formation" and the "post-caldera formation". A zonal arrangement of the alkali content of the Sunda arc volcanoes, i.e. an increase of the alkali content in the lavas across the arc from the trench to the backarc basin, has been noticed for many years. In contrast to the common classification of the geochemistry and magmatic affinity of the Javanese volcanoes related to the depth of the Benioff zone (100-150 km for tholeiitic rocks and 150-250 km for calc-alkaline rocks), we found a tholeiitic trend expressed by increasing FeO∗/MgO with increasing SiO 2 and an average {Zr}/{Y} ratio of 4.9 for the Tengger Caldera volcanics (Benioff zone depth ca 200 km), despite high alkali contents (K 2O > 2 wt%). These features characterize the Tengger Caldera volcanics as medium to high-K tholeiitic andesites and basaltic andesites.

    Changes in land use for housing indirectly disturb the hydrology balance of the area. Groundwater conservation efforts can be done by keeping the function the catchment area. One of the housing developer's obligations is providing open spaces (the playground) to play or activity of the residents. Playground in Bumi Graha Indah Housing, Jaten village, Karanganyar district, Central Java, Indonesia has a fundamental issue, that is, in the rainy season the water is difficult to seep due landfill process are not well planned. It causes the playground become in muddy conditions with tall grass, so that reduces the function as a playground and or activity the residents. In the dry season, the soil dry of landfill caused dust scattering and disrupt the activities of people around the playground. Lack of water resources lead watering process for solving the problem of dust during the dry season was considered ineffective. Structuring drainage combined with modified recharge wells can be used to catch water runoff housing. This modification of water catchment areas can make playground dry quickly after rain so the activities of people are not bothered when utilizing the open space provided. Surface runoff water absorbed in open aquifer so that the hydrological balance always be maintained. Adequacy groundwater in the area playground can be used to sprinkler dust and backup needs clean water residents by creating wells and reservoir stocks.

    The Government of the Republic of Indonesia has a mission to achieve food self-sufficiency in 2017, therefore it is necessary efforts to the stability of food needs. Karawang Regency as a granary states have a vital role in maintaining the national rice self-sufficiency, so indispensable information paddy field area. Paddy field accurate mapping can be done with a fast and efficient method of using remote sensing technology. This study aims to identify the paddy field using remote sensing technology. The data used is Landsat TM 2002 and Landsat-8 2015. The classification method using an approach Normalized Difference Vegetation Index (NDVI) and the Tasseled Cap Transformation (TCT). This method can be implemented to identify the fields that are still green or in the growing season. TCT produces three images of the six combinations, namely Brightness (BRT), greenness (GRN), and wetness (WET). BRT provides graytone gradation of non vegetation to water. GRN is indicated the gradation of vegetation cover, begin from densely vegetated until the most rare or non-vegetated areas. While wetness (WET) indicates the area associated with the presence of water. The main results of the classification is not a wetland and paddy. Based on existing data paddy land area of research area is ± 57% of the area of Karawang Regency.

    Full Text Available This study was designed to investigate the seasonal effect of gastrointestinal nematode parasitism on weight gain of recently weaned sheep and goats in an area of West Java. Most animals were allowed to graze during the day and kept in pens with a raised slatted floor during the night Three trials were conducted in tandem,each for a period of4 months . The effect of parasitism was assesed by comparing weight gain of untreated animals with that of otherwisesimilar group treated each 2 weeks with oxfendazole or albendazole to suppress nematode parasitism . There was no difference between weight gain of treated and untreated sheep and goats during the dry season . Moreover, during the dry season both treated and untreated sheep and goats grew at about twice the rate of untreated animals and 25 percent greater than treated animalsduring the wet season . As faecal egg counts (and, thus, presumably the level of parasitism were the same throughout the year it was concluded that the low level of nutrition during the wet season was the main determinant affecting pathogenicity of gastrointestinal nematode parasitism in this study. Furthermore, improved nutrition during the wet season in areas similar to that of this study, especially in sheep and goats for the first 10 weeks after weaning, may obviate the need for anthelmintic therapy, being a means to both increase weight gain and negate the effect of nematode parasitism

    Currently, the human deciduous dental record from the Pleistocene deposits of the Sangiran Dome, Java, consists of only eight specimens. Here we report two deciduous crowns collected near the village of Pucung. While their precise geo-chronological context remains unknown, a provenance from the Early-Middle Pleistocene Kabuh Formation, or from the Early Pleistocene "Grenzbank Zone," is very likely. These isolated specimens consist of an upper first molar (PCG.1) and a lower second molar (PCG.2). Taxonomic discrimination of the Indonesian tooth record is difficult because of the convergence in crown size and appearance between Pongo and Homo. Accordingly, as PCG.2 still bears a concretion masking most of its features, we coupled the outer analysis of the two specimens with an investigation of their inner morphology. In addition to external characteristics, virtual imaging and quantitative assessment of inner morphology and tissue proportions support an attribution to the taxon Homo, and we preliminary allocate both specimens toH. erectus.

    Full Text Available Metallic mineral exploration activities primarily base metals often have problems because the resources of metallic minerals located below surface are associated with the surrounding rock. Application of Induced Polarization method was carried out in the area of mineral prospects at Kasihan Village, Pacitan District, East Java. The Induced Polarization (IP data were taken by Syscal Junior 458, using Dipole-dipole and Wenner configuration for mapping and Schlumberger configuration for sounding. Magnetic data were obtained by Geotron Magnetometer. Estimation of pyrite mineral deposit was done using modeling of Res2Dinv and RockWork15. Combination of resistivity and chargeability is conducted to identify the boundaries of mineralization zones. The high resistivity value is correlated with the content of silicate minerals in the mineralized zone, whereas the higher chargeability means high degree of metallic mineral deposits (pyrite. The assesment of two different mineralized zones in metal content is known by combining chargeability and resistivity with magnetic anomaly.

    Lectins or carbohydrate-binding proteins, are widely distributed in nature, including in marine algae. It may have been considered that binding specificity of lectins to some carbohydrates provokes to produce many unique biological activities, including cell agglutination, mitogenic activity, and antitumor activity. The aim of this study was to determine the cytotoxicity of crude lectins from red macroalgae collected from the southern coast of Java Island, Gunung Kidul Regency, Yogyakarta against MCF-7 and HeLa cancer cells. In vitro MTT assay was used in this study. The results showed that less than 50% of MCF-7 and HeLa cancer cells growth were inhibited by the crude lectins from five species of red macro algae used in this study. The highest inhibition ability shown in the red alga A. nana was able to kill 47.68% of HeLa cervical cancer cells.

    Malariometric surveys were conducted during July 1996 in native Dayak villages and predominantly Javanese transmigration settlements in Ketapang district of West Kalimantan, Indonesia. Malaria prevalence ranged from 0.9% to 2.7% in Dayak villages and from 1% to 20% in the transmigration settlements. Plasmodium falciparum accounted for 67% of the cases among Dayaks but P. vivax was dominant among transmigrants, accounting for more than 72% of the infections. Chloroquine sensitivity/resistance was assessed by 28-day in vivo testing of uncomplicated malaria infections and measurement of chloroquine blood levels in cases where parasitemias reappeared within the 28-day test period. Resistance was based on the appearance of asexual parasites against chloroquine plus desethylchloroquine levels exceeding the minimally effective whole blood concentrations proposed for sensitive parasite strains (P. vivax, 100 ng/ml; P. falciparum, 200 ng/ml). All parasitemias cleared initially within four days of beginning supervised chloroquine therapy (25 mg base/kg over a 48-hr period), but asexual parasites reappeared within 28 days in 27 of 52 P. vivax and three of 12 P. falciparum cases. Chloroquine blood levels at the time of recurrent parasitemias revealed resistance in 12 of the 27 P. vivax cases and in one of the three P. falciparum cases. Genotypes of nine of the 12 recurrent P. vivax isolates matched with their primary isolates and ruled out reinfection. These findings establish the presence of chloroquine-resistant P. vivax on the island of Borneo. The pattern of malaria and the high frequency of chloroquine resistance by P. vivax at the West Kalimantan location may relate to demographic, ecologic, agricultural, and socioeconomic changes associated with transmigration.

    We report field observations together with petrological, geochemical and geochronological data from granitoids of the Netoni Intrusive Complex of West Papua. Until now, our knowledge of the timing of granitic magmatism in this region has been limited to a wide range of ages (241-6.7 Ma) obtained from K-Ar measurements of hornblende, biotite and plagioclase, primarily from samples of river detritus. We collected in situ samples along several traverses into the intrusive complex to: (1) develop a better understanding of the lithologies within the intrusive complex; and (2) determine the timing of magmatism using U-Pb dating of zircon. We also dated zircons from two river sand samples to identify other potential pulses of magmatism that may have been missed due to a sampling bias. The zircons extracted from the river sands yield age spectra similar to those obtained from the in situ samples. The combined data demonstrate that magmatism in the Netoni Intrusive Complex occurred between 248 Ma and 213 Ma. The petrological and geochemical data indicate that the granitoids were most likely emplaced in an ocean-continent (Andean style) subduction setting. This builds on previous work which suggests that a magmatic belt extended along eastern Gondwana (now New Guinea and eastern Australia) throughout much of the Paleozoic. The volcanic ejecta that were produced along this arc and the subsequent erosion of the mountain chain are a potential source of detritus for Triassic and younger sedimentary rocks in New Guinea, eastern Indonesia and north/northwestern Australia.

    After India and Brazil, Indonesia has the third highest incidence/prevalence of leprosy in the world. Every year thousands of new cases and case with grade-2 disability are reported and, while the recovery rate lingers only 80-90 %. Therefore, more than 10 % of leprosy patients drop out of treatment and can be a source of new infections in the community. Our research was aimed at determining apparent difficulties in the leprosy control program as well as how a health information system (HIS) could assist the Indonesian leprosy control program. We used qualitative method with deep interview and observation of document. One of the difficulties which the Indonesian leprosy control program faces is discontinuity of patient's data due to rotating staff as well as the treatment monitoring and queries patients which should be monitored after treatment has ceased. Technology implementation is feasible through short message service (sms) reminders and web base applications. The leprosy control program urgently needs to implement continuous monitoring and recording of patients because of the particular characteristics of this contagious disease.

    Segara Anakan, a mangrove-fringed coastal lagoon in Indonesia, has a high diversity of macrobenthic invertebrates and is increasingly affected by human activities. We found > 50 organic contaminants in water, sediment and macrobenthic invertebrates from the lagoon most of which were polycyclic aromatic compounds (PACs). Composition of PACs pointed to petrogenic contamination in the eastern lagoon. PACs mainly consisted of alkylated PAHs, which are more abundant in crude oil than parent PAHs. Highest total PAC concentration in sediment was above reported toxicity thresholds for aquatic invertebrates. Other identified compounds derived from municipal sewage and also included novel contaminants like triphenylphosphine oxide. Numbers of stored contaminants varied between species which is probably related to differences in microhabitat and feeding mode. Most contaminants were detected in Telescopium telescopium and Polymesoda erosa. Our findings suggest that more attention should be paid to the risk potential of alkylated PAHs, which has hardly been addressed previously.

    The using of a high quality seed is very important for a successfully cultivation and an increasing of vegetable production. The vegetable productions, including for shallot are much more affected by seed varieties. Previous studies showed that production rate, shape, colour, resistant to pest and disease, number of bulbs and demanding by market were factors that influence farmers to choose shallot variety. The aim of the study is to observe determinant factors that influence shallot farmers to change their shallot varieties and persist to use certain varieties. The study was conducted in June to December 2014 in Wanasari, Tanjung, Kemukten and Limbangan villages, Brebes District. Brebes was selected as it is the biggest shallot production in Indonesia. Data were collected from 35 shallot farmers through survey by using the structural questionnaire. The data then analysed with the descriptive statistic.

    The increase in human population as well as area development in Salatiga Groundwater Basin, Central Java Province, will increase the potency of groundwater contamination in that area. Groundwater quality, especially the shallow groundwater, is very vulnerable to the contamination from industrial waste, fertilizer/agricultural waste, and domestic waste. The first step in the conservation of groundwater quality is by conducting the mapping of the groundwater vulnerability zonation against the contamination. The result of this research was groundwater vulnerability map which showed the areas vulnerable to the groundwater contamination. In this study, groundwater vulnerability map was assessed based on the DRASTIC Method and was processed spatially using Geographic Information System. The DRASTIC method is used to assess the level of groundwater vulnerability based on weighting on seven parameters, which are: depth to the water table (D), recharge (R), aquifer material (A), soil media (S), topography (T), impact of vadose zone (I), and hydraulic conductivity (C). The higher the DRASTIC Index will result in the higher vulnerability level of groundwater contamination in that area. The DRASTIC Indexes in the researched area were 85 - 100 (low vulnerability level), 101 -120 (low to moderate vulnerability level), 121 - 140 (moderate vulnerability level), 141 - 150, (moderate to high vulnerability level), and 151 - 159 (high vulnerability level). The output of this study can be used by local authority as a tool for consideration to arrange the policy for sustainable area development, especially the development in an area affecting the quality of Salatiga Groundwater Basin.

    Full Text Available The study was aimed to explore the role of cooperativism in dairy cattle farming in Getasan village,Semarang Regency, Central Java Province. Spearman Rank Correlation test was used to determine therelationship between cooperativism and the performance of dairy cattle farming. Based on the results ofthe Spearman Rank correlation test, feeds and feeding practices were significantly correlated withsharing of knowledge and information and sharing of resources. However, no significant relationshipwas found between participation in decision making and feeds and feeding practices. Meanwhile, therewere significant relationships amog sharing of knowledge and information, sharing of resources, andparticipation in decision making and milk production in Getasan Village. The dairy health asperformance indicator of dairy cattle farming, sharing of knowledge and information was the onlysignificant factor. Sharing of resources and participation in decision making had no significantrelationship with dairy health. As regards marketing, the test showed that sharing of knowledge andinformation, sharing of resources, and participation in decision making were significantly relatedfactors. This study indicated that cooperativism may provide opportunities for farmers to accessservices, information and resources that will allow them to improve their capacities in these areas. Thisstudy also proposed some recommendations that the cooperatives should promote activities encouraginggreater cooperation and mutual understanding among the members. Skills trainings and education forempowerment should be conducted to encourage participation in decision making.

    To examine levels of bacterial contamination in formula feeding bottles in Sidoarjo, East Java, and to assess the preparation practices that may have been responsible. A cross-sectional study was conducted among 92 randomly selected households with children under the age of two who were bottle-fed formula. In each household, we carried out video observation of mothers/caregivers preparing bottles, and examined samples of formula for coliform bacteria and Escherichia coli (E. coli). In-depth interviews were conducted with a subsample of 20 mothers. A total of 88% of the formula feeds were contaminated with total coliforms at a level >10 MPN/ml, and 45% contained E. coli. These feeds were defined as 'unfit for human consumption'. In the video observations, none of the mothers complied with all five WHO-recommended measures of hygienic formula feed preparation. Only two mothers washed their hands with soap prior to formula preparation. Most mothers also failed to clean or sterilise the bottle and clean the preparation area. In-depth interviews confirmed that such suboptimal hygiene practices were common. The high levels of contamination found highlight that bottles are an important faecal-oral exposure pathway resulting from poor hygiene practices during bottle preparation. © 2017 John Wiley & Sons Ltd.

    Lamuntet is one of gold ore mining area carried out by the Artisanal Small scale Gold Mining (ASGM) located in West Sumbawa, Indonesia. Most of the miners at this area are not the local miners but also those from other regions. Mineralization of this area is strong identified as low sulfidation epithermal system. There are two blocks of this mining location, namely, Ngelampar block with an area of 0.164 km2 and Song block with an area of 0.067 km2. This study was focused on Ngelampar block. The characteristic of epithermal system is the existence of quartz vein with comb, vuggy, and sugary texture. The aim of this research was to analyze the gold grade and other metals, such as Cu, Ag, Pb, As, Zn, and Hg. The research methods included literature study from previous researches, field work, laboratory work, and interpretation. The literature study was performed on previous researches with similar study area. The field work comprised of direct observation and sampling. Fieldwork was done for a week to obtain gold ore/vein. Sixteen samples were analyzed to obtain the grade of ore/metal. The Hg laboratory analysis was then performed on the six samples with the highest gold grade. Laboratory works were conducted at Intertek Jakarta by using Fire Assay (FA) for gold grade and Atomic Absorption Spectrophotometry (AAS) for Cu, Ag, Pb, As, Zn, and Hg. Results of the analysis showed the range of Au was grade (0.1 ppm - 27.8 ppm), Cu was 26 ppm -1740 ppm, Pb was 101 ppm- >4000 ppm, Zn of 73 ppm- >10,000 ppm, Ag of 3 ppm -185 ppm, As was 150 ppm-6530 ppm, and Hg of 0.08 ppm - 1.89 ppm. L1 and L15 had high grade for all values (Au, Ag, Zn, Cu, As, and Hg). Gold mineralization was formed as electrum because of Ag content is higher than 20%. Associated minerals of the samples in the study area were galena, sphalerite, arsenopyrite, and chalcopyrite which showed the characteristic of rich base metal of Pb, Zn, and Cu at LS epithermal.

    Indonesia is one of the countries most severely affected by H5N1 highly pathogenic avian influenza (HPAI) virus in terms of poultry and human health. However, there is little information on the diversity of H5N1 viruses circulating in backyard farms, where chickens and ducks often intermingle. In this study, H5N1 virus infection occurring in 96 smallholder duck farms in central Java, Indonesia from 2007-2008 was investigated and the molecular and antigenic characteristics of H5N1 viruses isolated from these farms were analysed. All 84 characterised viruses belonged to H5N1 clade 2.1 with three virus sublineages being identified: clade 2.1.1 (1), clade 2.1.3 (80), and IDN/6/05-like viruses (3) that did not belong to any of the present clades. All three clades were found in ducks, while only clade 2.1.3 was isolated from chickens. There were no significant amino acid mutations of the hemagglutinin (HA) and neuraminidase (NA) sites of the viruses, including the receptor binding, glycosylation, antigenic and catalytic sites and NA inhibitor targets. All the viruses had polybasic amino acids at the HA cleavage site. No evidence of major antigenic variants was detected. Based on the HA gene, identical virus variants could be found on different farms across the study sites and multiple genetic variants could be isolated from HPAI outbreaks simultaneously or at different time points from single farms. HPAI virus was isolated from both ducks and chickens; however, the proportion of surviving duck cases was considerably higher than in chickens. The 2.1.3 clade was the most common lineage found in this study. All the viruses had sequence characteristic of HPAI, but negligible variations in other recognized amino acids at the HA and NA proteins which determine virus phenotypes. Multiple genetic variants appeared to be circulating simultaneously within poultry communities. The high proportion of live duck cases compared to chickens over the study period suggests that ducks are

Results All 84 characterised viruses belonged to H5N1 clade 2.1 with three virus sublineages being identified: clade 2.1.1 (1, clade 2.1.3 (80, and IDN/6/05-like viruses (3 that did not belong to any of the present clades. All three clades were found in ducks, while only clade 2.1.3 was isolated from chickens. There were no significant amino acid mutations of the hemagglutinin (HA and neuraminidase (NA sites of the viruses, including the receptor binding, glycosylation, antigenic and catalytic sites and NA inhibitor targets. All the viruses had polybasic amino acids at the HA cleavage site. No evidence of major antigenic variants was detected. Based on the HA gene, identical virus variants could be found on different farms across the study sites and multiple genetic variants could be isolated from HPAI outbreaks simultaneously or at different time points from single farms. HPAI virus was isolated from both ducks and chickens; however, the proportion of surviving duck cases was considerably higher than in chickens. Conclusions The 2.1.3 clade was the most common lineage found in this study. All the viruses had sequence characteristic of HPAI, but negligible variations in other recognized amino acids at the HA and NA proteins which determine virus phenotypes. Multiple genetic variants appeared to be circulating simultaneously within poultry communities. The high proportion of live duck cases compared to

    The Government has intervened to deal with various affordable public housing programs, as well as financing programs for Low Income society in Indonesia. The characteristics of this society in each region are so diverse, that made the housing programs for this social segment uneasy in reaching the right target. Regulation of Housing and Settlement No. 2/2001 has mandated that the State are obliged to implement a habitable public housing for people, especially for the low income society. The purpose of this study is exploring the low-income residents' preferences and affordability of home ownership for their families in the poorest sub-district of Semarang. Aspects of studies include family conditions, financing, location, housing type and price. The research used a descriptive method to analyze a set of questionnaire data, distributed to low income residents in Sub district Tanjungmas, which isthe poorest sub district in Semarang. The results showed that the respondents developed a vision of home ownership by saving their money for the allocated housing budget and taking a bank installment. They tended to plan to get a house in their current neighborhood or nearby or anywhere else with the same price range. They really understood that, in order to get a better home and neighborhood they have to pay for higher prices. Therefore, their housing criteria or standards were set based on the quality of life in their current residential area, and should be located in a township (kampung).

    Full Text Available The present paper reflects on Indonesia’s status as an archipelagic state and a maritime nation from a historical perspective. It explores the background of a multi-year research project into Indonesia’s maritime past currently being undertaken at the Humanities Faculty of Universitas Indonesia. The multidisciplinary research uses toponymy, epigraphy, philology, and linguistic lines of analysis in examining old inscriptions and manuscripts and also includes site visits to a number of old port cities across the archipelago. We present here some of the core concepts behind the research such as the importance of the ancient port cities in a network of maritime trade and diplomacy, and link them to some contemporary issues such as the Archipelagic Outlook. This is based on a concept of territorial integrity that reflects Indonesia’s national identity and aspirations. It is hoped that the paper can extend the discussion about efforts to make maritime affairs a strategic geopolitical goal along with restoring Indonesia’s identity as a maritime nation.

    Full Text Available Bayat Complex is usually used as a work field for students of geology and other geosciences. The study area is located in the southern part of the Bayat Complex. Administratively, it belongs to Central Java Province and Yogyakarta Special Province. The lithology of Bayat is very complex, composed of various kinds of igneous, sedimentary, metamorphic, and volcanic rocks. Most of previous researchers interpreted Bayat as a melange complex constructed within a subduction zone. Kebo-Butak is one of formations that forms the Bayat field complex. The formation is composed of basalt, layers of pumice, tuff, shale, and carbonaceous tuff. Most of them are known as volcanic rocks. These imply that volcanic activities are more probable to construct the geology of Bayat rather than the subducted melange complex. The geological mapping, supported by geomorphology, petrology, stratigraphy, and geological structures, had been conducted in a comprehensive manner using the deduction-induction method. The research encounters basalt, black pumice, tuff with basaltic glasses fragments, zeolite, argilic clay, as well as feldspathic- and pumice tuff. Petrographically, the basalt is composed of labradorite, olivine, clinopyroxene, and volcanic glass. Black pumice and tuff contain prismatic clinopyroxene, granular olivine, and volcanic glasses. Feldspathic tuff and pumice tuff are crystal vitric tuff due to more abundant feldspar, quartz, and amphibole than volcanic glass. Zeolite comprises chlorite and altered glasses as deep sea altered volcanic rocks. The geologic structure is very complex, the major structures are normal faults with pyrite in it. There were two deep submarine paleovolcanoes namely Tegalrejo and Baturagung. The first paleovolcano erupted effusively producing basaltic sequence, while the second one erupted explosively ejecting feldspathic-rich pyroclastic material. The two paleovolcanoes erupted simultaneously and repeatedly.

    Galunggung volcano, Java, awoke from a 63-year quiescence in April 1982, and erupted sporadically through January 1983. During its most violent period from April to October, the Cikasasah Volcano Observatory reported 32 large and 56 moderate to small eruptions. From April 5 through September 19 the Total Ozone Mapping Spectrometer (TOMS), carried on NASA's Nimbus-7 satellite, detected and measured 24 different sulfur dioxide clouds; an estimated 1730 kilotons (kt) of SO2 were outgassed by these explosive eruptions. The trajectories, and rapid dispersion rates, of the SO2 clouds were consistent with injection altitudes below the tropopause. An additional 300 kt of SO2 were estimated to have come from 64 smaller explosive eruptions, based on the detection limit of the TOMS instrument. For the first time, an extended period of volcanic activity was monitored by remote sensing techniques which enabled observations of both the entire SO2 clouds produced by large explosive eruptions (using TOMS), and the relatively lower levels of SO2 emissions during non-explosive outgassing (using the Correlation Spectrometer, or COSPEC). Based on COSPEC measurements from August 1982 to January 1983, and on the relationship between explosive and non-explosive degassing, approximately 400 kt of SO2 were emitted during non-explosive activity. The total sulfur dioxide outgassed from Galunggung volcano from April 1982 to January 1983 is calculated to be 2500 kt (?? 30%) from both explosive and non-explosive activity. While Galunggung added large quantities of sulfur dioxide to the atmosphere, its sporadic emissions occurred in relatively small events distributed over several months, and reached relatively low altitudes, and are unlikely to have significantly affected aerosol loading of the stratosphere in 1982 by volcanic activity. ?? 1994.

    It is hypothesized that rise in temperature under climate change regimes can cause oxygen depletion and can reduce the diversity and population of plankton and decrease the potential food source for fish in ponds. Therefore, this paper aims to investigate the primary factors that can affect the planktonic community with emphasis on temperature rise and oxygen depletion. Sampling was conducted in Blanakan, West Java. Samples were assessed to determine levels of planktonic community and other water quality parameters. DO was monitored in situ along with pH and temperature. Based on the results, the temperature average in ponds was 31.88±1.93 °C and ranged from 29.0 to 35.0 °C. The DO average was 7.63±0.59 mg/l and ranged from 7.0 to 8.5 mg/l. The rise of pond temperature affected slighltyto the DO and had reduced the DO level to the lowest level (7.0-7.2 mg/l) when temperature reached its peak at 32.5-35.0 °C. The results showed that the oxygen depletion will significantly reduce the phytoplankton population (r2=0.54). However, the oxygen depletion did not affect the plankton diversity. The results revealedthe presence of 23 genera of phytoplankton and 18 genera for zooplankton in Blanakan ponds. Nitzchia and Pleurosigma were known as genera that can adapt both in the DOmin and DOmax environment (7.0-8.5 mg/l). At aquaculture scale, temperature has potential to influence oxygen level and affect planktonic community. It is recommended to provide natural shades and develop aeration systems to increase oxygen levels in ponds.

    Lembang and Cimandiri fault are active faults in West Java that thread people near the faults with earthquake and surface deformation risk. To determine the deformation, GPS measurements around Lembang and Cimandiri fault was conducted then the data was processed to get the horizontal velocity at each GPS stations by Graduate Research of Earthquake and Active Tectonics (GREAT) Department of Geodesy and Geomatics Engineering Study Program, ITB. The purpose of this study is to model the displacement distribution as deformation parameter in the area along Lembang and Cimandiri fault using 2-dimensional boundary element method (BEM) using the horizontal velocity that has been corrected by the effect of Sunda plate horizontal movement as the input. The assumptions that used at the modeling stage are the deformation occurs in homogeneous and isotropic medium, and the stresses that acted on faults are in elastostatic condition. The results of modeling show that Lembang fault had left-lateral slip component and divided into two segments. A lineament oriented in southwest-northeast direction is observed near Tangkuban Perahu Mountain separating the eastern and the western segments of Lembang fault. The displacement pattern of Cimandiri fault shows that Cimandiri fault is divided into the eastern segment with right-lateral slip component and the western segment with left-lateral slip component separated by a northwest-southeast oriented lineament at the western part of Gede Pangrango Mountain. The displacement value between Lembang and Cimandiri fault is nearly zero indicating that Lembang and Cimandiri fault are not connected each other and this area is relatively safe for infrastructure development.

    Food supply is considered as one of the most vulnerable to the effects of climate change. Higher temperature and changes in rainfall patterns and intensity may adversely impact crop production, which will eventually affect the food supply. Consequently, adaptation strategies should be devised to minimize the potential adverse impacts and maximize its potential benefits. The adaptation strategies should be devised by considering factors contributed to causing vulnerability following the concept of food supply chain, starting from production to consumption. This study focuses on identifying the contributed factors to vulnerability of crop production regions in Indonesia. The contributed factors were identified by defining indicators for each component of the food supply chain using an example of crop production centers in Indonesia, the West Java Province. The identification considers existing issues of the food supply chain, covering aspects of production, post-harvest and storage, distribution, and consumption, based on the field surveys conducted in Indramayu district of the West Java, the main grower of paddy production, and Garut district of the West Java, the main grower of corn production. The selection of the vulnerability indicators was also considered the data availability for the study area. The analysis proposed a list of indicators classified into production, post-harvest and storage, distribution and consumption that are proposed to assess the regional vulnerability of crop production regions in Indonesia. This result is expected to contribute in understanding the process of devising climate change adaptation intended for enhancing food supply resilience to climate change.

    Full Text Available Abstract Background The West Sumatra earthquake that occurred on September 30, 2009, caused severe damage in some districts, including Padang Pariaman. As Padang Pariaman is an earthquake-prone area, disaster and emergency management is necessary. Due to the limited health facilities, the health services completely rely on Puskesmas (Primary Health Centres, PHCs. This study is aimed at assessing the preparedness of PHCs to response to potential disasters in their surrounding area. Findings Padang Pariaman district was used in a case study setting to assess the readiness and preparedness of the PHCs there to face disasters. Self-administered questionnaire, key informant interview, and direct observation were used to obtain the data on human resources, facilities preparedness, and the procedures. The investigation focused on measuring four aspects, i.e. human resources, facilities preparedness, standard operating procedure (SOP, and policy. Due to the limited co-operation of the head of the PHCs, three PHCs were directly observed as a subsample. The evaluation was performed six months after the impact phase of the earthquake and three months after the PHCs' health staff training on improving the primary health care services. The number and quality of health staff in Padang Pariaman was far below ideal. Fewer than half of the PHCs had emergency facilities and only one considered the need for triage and fire management, whereas the transportation mode was still limited. An SOP and policy for facing disasters were not available in any of the PHCs. Therefore, promoting disaster preparedness, technical provision, including health staff training, is necessary. Conclusions Padang Pariaman district has not yet prepared its PHCs to face disaster, so it is apparent that PHCs' disaster preparedness in Padang Pariaman and also other earthquake-prone areas in Indonesia should be promoted. This should include increasing the number of doctors, providing training

    To determine whether prenatal vitamin A and/or Zn supplementation affects postnatal growth. Follow-up of a randomized controlled trial monitoring growth in children from birth up to 24 months of age. Central Java, Indonesia. Children (n 343) of mothers participating in a double-blinded, randomized controlled study of vitamin A and/or Zn supplementation during pregnancy. We report the effects of prenatal supplementation on infant growth, measured as weight-for-age Z-scores (WAZ), height-for-age Z-scores (HAZ) and weight-for-height Z-scores (WHZ ), from 0 to 24 months, as well as differences in growth faltering among the supplementation groups. For HAZ, the absolute differences between the vitamin A-only and vitamin A + Zn groups at 3 and 9 months were 0·34 SD and 0·37 SD, respectively, and the absolute difference between the vitamin A-only and Zn-only groups at 18 months was 0·31 SD. Compared with placebo, none of the supplements affected growth. Defining growth faltering as a downward crossing of two or more major percentile lines, 50-75% of the children were found to be growth faltering within 9 months of age, whereas 17% and 8% scored <-2 SD for WAZ and HAZ, respectively. Prenatal supplementation did not reduce the prevalence of growth faltering. Prenatal vitamin A supplementation had a small but significant effect on postnatal growth of children's length until 18 months of age compared with supplementation with either vitamin A + Zn or Zn alone, but not compared with placebo. It had no effects on other anthropometric measures and did not reduce the prevalence of growth faltering. Future studies should duplicate these findings before recommendations can be made.

    Rapid development of Surabaya City requires space for industry and settlement. The city development is followed by increasing of water demand for various purposes. Large amount of groundwater extraction may cause ground subsidence. According to groundwater extraction, we tried to delineate the possibility of aquifer potential based on ground surface deformation using Interferometric Synthetic Aperture Radar (InSAR) and Electrical Resistivity methods. The InSAR is a method to estimate surface deformation in millimeter scale based on different phase of SAR data between acquisition times. In this paper, surface deformation combined with ground resistivity was used to analyse the potential of aquifer related to subsidence at Surabaya City, East Java, Indonesia. The Small Based Subset (SBAS) method was used to reduce phase delayed in the interferogram due to atmospheric condition. Based on the SBAS InSAR the deformation was detected at Surabaya City in January 2007 to February 2008. The largest and lowest deformation about 40 mm/year and about 0-10 mm/year were located in North to Southeastern and Western part of the city, respectively. The geodetic Global Positioning System (GPS) campaign in Surabaya confirmed that the detected deformation correlated with the ground subsidence with correlation coefficient about 0.96. To obtain the subsurface structures at subsidence zones, the Electrical Resistivity survey with Schlumberger configuration was performed in Surabaya city. According to the SBAS InSAR and subsurface resistivity, the subsidence around Pabeancantikan, Kenjeran, Simokerto and Tenggilismejoyo sub-districts agreed to high resistivity about 7-18 Ωm. The Sandstone of Kabuh and Pucangan formations in this area served as ground water aquifer which used by more than 200 wells. Ground water extraction probably triggered the subsidence at ground surface. The high resistivity at subsidence zones originated from high porosity of rocks served as aquifer with high

    We describe a new species of Cylindrophis currently known only from Grabag, Purworejo Regency, Jawa Tengah Pro-vince (Central Java), Java, Indonesia. Cylindrophis subocularis sp. nov. can be distinguished from all congeners by the presence of a single, eponymous subocular scale between the 3rd and 4th or 4th and 5th supralabial, preventing contact between the 4th or 5th supralabial and the orbit, and by having the prefrontal in narrow contact with or separated from the orbit. We preface our description with a detailed account of the tangled taxonomic history of the similar and putatively wide-ranging species C. ruffus, which leads us to (1) remove the name Scytale scheuchzeri from the synonymy of C. ruffus, (2) list the taxon C. rufa var. javanica as species inquirenda, and (3) synonymize C. mirzae with C. ruffus. We provide additional evidence to confirm that the type locality of C. ruffus is Java. Cylindrophis subocularis sp. nov. is the second species of Asian pipesnake from Java.

    In the health sectors of low- and middle-income countries, contingent valuation method (CVM) studies on willingness to pay (WTP) have been used to gather information on demand variation or financial perspectives alongside price setting, such as the introduction of user fees and valuation of quality improvements. However, WTP found in most CVM studies have only explored the preferences that consumers express through their WTP without exploring whether they are actually able to pay for it. Therefore, this study examines the issues pertaining to WTP estimation for health services using the conventional CVM. We conducted 202 household interviews in 2008, in which we asked respondents about three types of public health services in Indonesia and assessed WTP estimated by the conventional CVM as well as in the scenario of "resorting to debt" to recognize their budget constraints. We find that all the demand curves for both WTP scenarios show gaps. Furthermore, the gap for midwife services is negatively affected by household income and is larger for the poor. These results prove that CVM studies on WTP do not always reveal WTP in the latter scenario. Those findings suggest that WTP elicited by the conventional CVM is different to that from the maximum price that prevents respondents from resorting to debt as their WTP. In order to bridge this gap in the body of knowledge on this topic, studies should improve the scenarios that CVM analyses use to explore WTP. Furthermore, because valuing or pricing health services based on the results of CVM studies on WTP alone can exacerbate the inequity of access to these services, information provided by such studies requires careful interpretation when used for this purpose, especially for the poor and vulnerable sections of society.

    Homo erectus was the first human lineage to disperse widely throughout the Old World, the only hominin in Asia through much of the Pleistocene, and was likely ancestral to H. sapiens. The demise of this taxon remains obscure because of uncertainties regarding the geological age of its youngest populations. In 1996, some of us co-published electron spin resonance (ESR) and uranium series (U-series) results indicating an age as young as 35-50 ka for the late H. erectus sites of Ngandong and Sambungmacan and the faunal site of Jigar (Indonesia). If correct, these ages favor an African origin for recent humans who would overlap with H. erectus in time and space. Here, we report (40)Ar/(39)Ar incremental heating analyses and new ESR/U-series age estimates from the "20 m terrace" at Ngandong and Jigar. Both data sets are internally consistent and provide no evidence for reworking, yet they are inconsistent with one another. The (40)Ar/(39)Ar analyses give an average age of 546±12 ka (sd±5 se) for both sites, the first reliable radiometric indications of a middle Pleistocene component for the terrace. Given the technical accuracy and consistency of the analyses, the argon ages represent either the actual age or the maximum age for the terrace and are significantly older than previous estimates. Most of the ESR/U-series results are older as well, but the oldest that meets all modeling criteria is 143 ka+20/-17. Most samples indicated leaching of uranium and likely represent either the actual or the minimum age of the terrace. Given known sources of error, the U-series results could be consistent with a middle Pleistocene age. However, the ESR and (40)Ar/(39)Ar ages preclude one another. Regardless, the age of the sites and hominins is at least bracketed between these estimates and is older than currently accepted.

    It is unclear how best to go about improving child feeding practices. We studied the effect of a novel behaviour change intervention, Gerakan Rumpi Sehat (the Healthy Gossip Movement), on infant and young child feeding practices in peri-urban Indonesia. The pilot intervention was designed based on the principles of a new behaviour change theory, Behaviour Centred Design (BCD). It avoided educational messaging in favour of employing emotional drivers of behaviour change, such as affiliation, nurture and disgust and used television commercials, community activations and house-to-house visits as delivery channels. The evaluation took the form of a 2-arm cluster randomised trial with a non-randomised control arm. One intervention arm received TV only, while the other received TV plus community activations. The intervention components were delivered over a 3-month period in 12 villages in each arm, each containing an average of 1300 households. There were two primary outcomes: dietary diversity of complementary food and the provision of unhealthy snacks to children aged 6-24 months. Dietary diversity scores increased by 0.8 points in the arm exposed to TV adverts only (95% CI: 0.4-1.2) and a further 0.2 points in the arm that received both intervention components (95% CI: 0.6-1.4). In both intervention arms, there were increases in the frequency of vegetable and fruit intake. We found inconsistent evidence of an effect on unhealthy snacking. The study suggests that novel theory-driven approaches which employ emotional motivators are capable of having an effect on improving dietary diversity and the regularity of vegetable and fruit intake among children aged 6-24 months. Mass media can have a measurable effect on nutrition-related behaviour, but these effects are likely to be enhanced through complementary community activations. Changing several behaviours at once remains a challenge. © 2016 The Authors. Tropical Medicine & International Health Published by John Wiley

    This paper explores design event and entrainment of cay beach sands due to wave shear stresses from winds. Univariate frequency analysis is used to predict recurrence intervals of extreme winds from 30-year (1984-2013) global assimilated data set. Two primary clusters of wind directions representing East and West monsoons are examined. This identifies the equivalence of characteristics of regime among the two clusters. Taking into account the threshold of bottom shear stress of cay beach sands, conceptual relationship between height of wind-generated waves (forecasted from predefined fetch length and wind speed) and erosion of cay beach sand is prescribed. The results indicate that East monsoon is the predominant occurrence of wind and facilitates persistent north-westward shift of cay beach sands, while West monsoon provides extreme events in shorter time span. It is suspiciously thought that due to these, net north-westward drift of sand is indicated. These imply that many of cays in the domain being investigated is at risk of erosion due to unequal balance forcing of winds.

    Full Text Available Abstract Background Pulmonary tuberculosis (TB is a major health problem worldwide. Detection of the most infectious cases of tuberculosis – sputum smear-positive pulmonary cases – by passive case finding is an essential component of TB control. The district of Sidoarjo in East Java reported a low case detection rate (CDR of 14% in 2003. We evaluated the diagnostic process for TB in primary health care centers (PHC in Sidoarjo district to assess whether problems in identification of TB suspects or in diagnosing TB patients can explain the low CDR. Methods We performed interviews with the staff (general nurse, TB worker, laboratory technician, and head of health center of the 25 PHCs of Sidoarjo district to obtain information about the knowledge of TB, health education practices, and availability of support services for TB diagnosis. The quality of the laboratory diagnosis was examined by providing 10 slides with a known result to the laboratory technicians for re-examination. Results Eighty percent of the nurses and 84% of the TB workers knew that cough >3 weeks can be a symptom of TB. Only 40% of the nurses knew the cause of TB, few could mention complications of TB and none could mention the duration of infectiousness after start of treatment. Knowledge of TB workers was much better. Information about how to produce a good sputum sample was provided to TB suspects by 76% of the nurses and 84% of the TB workers. Only few provided all information. Fifty-five percent of the 11 laboratory technicians correctly identified all positive slides as positive and 45% correctly identified 100% of the negative slides as negative. All TB workers, one general nurses and 32% of the laboratory technicians had received specific training in TB control. There has been no shortage of TB forms and laboratory materials in 96% of the PHCs. Conclusion The quality of the diagnostic process for TB at PHC in Sidoarjo district should be improved on all levels

    Salmonella enterica subspecies enterica serovar Paratyphi B [O1,4,(5),12 : Hb : 1,2] can cause either an enteric fever (paratyphoid fever) or self-limiting gastroenteritis in humans. The d-tartrate non-fermenting variant S. enterica subsp. enterica serovar Paratyphi B dT- (S. Paratyphi B) is the causative agent of paratyphoid fever, and the d-tartrate fermenting variant S. enterica subsp. enterica serovar Paratyphi B dT+ (S. Paratyphi B dT+; formerly called Salmonella Java) causes gastroenteritis. S. Java is currently recognized as an emerging problem worldwide. Twelve dT+ S. Java isolates were collected in Indonesia between 2000 and 2002. One-third of them contained Salmonella genomic island 1 (SGI1), which gives the multidrug-resistant phenotype to the bacteria. In this study, a PCR-based method to detect a single nucleotide difference responsible for the inability to ferment d-tartrate, reported elsewhere, was validated. The d-tartrate fermenting phenotype of S. Java was converted to the non-fermenting phenotype by the disruption of the ORF STM 3356, and the d-tartrate non-fermenting phenotype of the ORF STM 3356-disrupted strain and the dT- reference strain was changed to the dT+ phenotype by complementing ORF STM 3356 in trans. The results show that the dT+ phenotype requires a functional product encoded by STM 3356, and support the use of the PCR-based discrimination method for S. Paratyphi B and S. Java as the standard differentiation method.

    A cross-shore morphodynamic model can be used to simulate shoreline recovery after extreme events, as shown here for the coast of West Aceh, Indonesia, a region largely affected by the December 2004 Sumatra-Andaman earthquake and ensuing Indian Ocean tsunami. Subsidence of 50-100 cm and tsunami scouring during the 2004 event caused the complete destruction of the beach and the landward displacement of the western Acehnese coast by an average of 110 m. Modeled post-seismic land elevation changes as a result of afterslip and viscoelastic mantle relaxation, indicate rapid uplift of 4.4 cm/year in the year following the earthquake, but more moderate uplift rates of 1.4 cm/year since mid-2006. Comparing a series of topographic surveys and satellite images, we reconstruct the build-up of a new beach ridge along a 10 km long stretch of coastline in the years following the event. We then use the cross-shore model UNIBEST-TC developed for a wave-dominated sandy shoreline to determine the controlling factors of shoreline recovery. Input parameters include bathymetric data measured in 2015, grain size characteristics of offshore sediment samples, modeled wave data computed in 7m water depth and tidal elevation data from a nearby tide gauge station. After establishing a cross-shore profile in equilibrium with the prevailing hydrodynamic conditions, we simulate post-seismic land level changes for up to 10 years and compare to the observed coastal development. Our data indicates that the recovery of the Western Acehnese shoreline after the 2004 event was incomplete with the shoreline stabilizing 40-80 meter landward of its pre-2004 tsunami position. Measured variability in shoreline position in the order of a few tens of meters since 2009 can be attributed to seasonal wave climate variability related to the monsoon cycle. The effect of postseismic uplift on shoreline position is small and in the order of only a few meters over 10 years. In the near future, continuing post

    Recent research in the coastal regions of Aceh, Indonesia, an area that was largely affected by the 2004 Sumatra Andaman earthquake and ensuing Indian Ocean tsunami, suggests the possibility that two closely spaced tsunamis occurred at the turn of the 14th to 15th century (Meltzner et al., 2010; Sieh et al., 2015). Here, we present evidence of two buried sand layers in the coastal marshes of West Aceh, possibly representing these penultimate predecessors of the 2004 tsunami. We discovered the sand layers in an until recently inaccessible area of a previously studied beach ridge plain about 15 km North of Meulaboh, West Aceh. Here, the 2004 tsunami left a continuous, typically a few cm thick sand sheet in the coastal hinterland in low-lying swales that accumulate organic-rich deposits and separate the sandy beach ridges. In keeping with the long-term progradation of the coastline, older deposits have to be sought after further inland. Using a hand auger, the buried sand layers were discovered in 3 cores in a flooded and highly vegetated swale in about 1 km distance to the shoreline. The pair of sand layers occurs in 70-100 cm depth and overlies 40-60 cm of dark-brown peat that rests on the basal sand of the beach ridge plain. The lower sand layer is only 1-6 cm thick, whereas the upper layer is consistently thicker, measuring 11-17 cm, with 8-14 cm of peat in between sand sheets. Both layers consist of massive, grey, medium sand and include plant fragments. They show very sharp upper and lower boundaries clearly distinguishing them from the surrounding peat and indicating an abrupt depositional event. A previously developed age model for sediments of this beach ridge plain suggest that this pair of layers could indeed correlate to a nearby buried sand sheet interpreted as tsunamigenic and deposited soon after 1290-1400AD (Monecke et al., 2008). The superb preservation at this new site allows the clear distinction of two depositional events, which, based on a first

    On May 29, 2006, mud and gases began erupting from a vent 150 meters away from a gas exploration well near Sidoarjo, East Java, Indonesia. The eruption, called the LUSI mud volcano, has continued at rates as high as 160,000 m3 per day. At the request of the United States Department of State, the U.S. Geological Survey (USGS) has been providing technical assistance to the Indonesian Government on the geological and geochemical aspects of the mud eruption. This paper will present analytical results of mud samples collected in Sept. 2007 and Nov. 2008, and interpretive findings based on the analytical results. The 2007 mud sample contains high proportions of particles that could be ingestible by hand-mouth transmission (~98 vol % petroleum source rocks. Although the 2007 mud sample contains several percent iron sulfides, net acid production tests indicate that enough carbonate material is also present to prevent the mud from becoming acid-generating due to weathering and sulfide oxidation in the near-surface environment. Water derived from settling mud deposits may have the potential to adversely affect the quality of surface- or groundwater sources for drinking water, due to high levels of fluoride, nitrate, iron, manganese, aluminum, sulfate, chloride, and total dissolved solids. The very high nitrate levels in the waters contained within the mud may present a source of nutrients that could enhance algal blooms and resulting adverse impacts such as hypoxia in fresh-water and marine ecosystems into which some of the mud is being discharged. In agreement with previous studies, water separated from the 2007 mud sample is compositionally and isotopically compatible with an origin as sedimentary formation water. The iron disulfide fraction of the mud sample is isotopically light, and likely formed by bacterial sulfate reduction during diagenesis of clay-rich rocks from which the mud was derived. A smaller, isotopically heavy monosulfide fraction likely formed later by

    The unprecedented 26 May 2006 Yogyakarta earthquake (central Java, Indonesia) that took victims of 5,700 lives was generally accepted to have a depth of about 10 km and moment magnitude of 6.4. However, the definition of location of active fault is still under debate as the epicenter of mainshock was reported quite differently by several institutions. Many researchers believe that the Opak fault which is located at the eastern boundary of Yogyakarta low-land area (or Yogyakarta Basin) and the high-land region of Southern Mountains was the source of year 2006 earthquakes. However, our result of aftershocks observation suggests that the ruptured zone was not located along the Opak fault but from an unknown fault located about 10 km to the east from it and within the Southern Mountains domain. Unfortunately, surface geologic manifestations are scarce as this area is now largely covered by limestone. Therefore the suspected active fault system must be studied through interpretations of the subsurface geology and evaluation of the Cenozoic geo-history of the region utilizing existing geologic, geophysical and remote sensing data. This work suggests that the Yogyakarta Basin is a volcano-tectonic depression formed gradually since the early Tertiary period (Oligo-Miocene or older). Geological and geophysical evidence suggest that structural trends changed from the Oligocene NE-SW towards the Oligo-Miocene NNE-SSW and the Plio-Pleistocene NW-SE and E-W directions. The ruptured "X" fault during the Yogyakarta earthquakes 2006 is likely to be a NNE-SSW trending fault which is parallel to the Opak fault and both were firstly active in the Oligo-Miocene as sinistral strike-slip faults. However, while the Opak fault had changed into a normal faulting after the Pliocene, the evidence from Kali Ngalang and Kali Widoro suggests that the "X" fault system was still reactivated as a strike-slip one during the Plio-Pleistocene orogeny. As this new interpretation of active fault causes
