    Full Text Available Isu pertanian organik akhir-akhir ini memang mulai berkembang kembali dengan semakin banyaknya masyarakat yang menyadari pentingnya kesehatan dan mutu bahan pangan yang dikonsumsi. Selain alasan kesehatan, pertanian organik juga diyakini ramah lingkungan karena dapat meminimalkan penggunaan bahan kimia dalam proses produksinya, karena penggunaan pupuk kimia secara terus-menerus dengan dosis yang meningkat justru dapat menyebabkan tanah menjadi keras dan keseimbangan unsur hara tanah terganggu.  Permintaan pasar terhadap tanaman sayuran khususnya selada yang biasanya dikonsumsi mentah terus meningkat, apalagi tanaman selada yang dipupuk dengan pupuk organik. Tanah di Kota Pekanbaru tergolong tanah Podsolid Merah Kuning (PMK yang kandungan bahan organik dan unsur haranya relatif rendah, maka salah satu usaha untuk mengatasi masalah tersebut adalah dengan cara pemupukan yang aman bagi tanaman dan tanah yaitu pupuk bokhasi eceng gondok yang mengandung unsur hara N, P dan K, juga memanfaatkan yang ada di lingkungan yang kalau tidak dimanfaatkan akan menyebabkan pencemaran di perairan.  Dari penelitian yang dilakukan pemberian bokhasi eceng gondok berpengaruh nyata terhadap pertumbuhan dan produksi tanaman selada dengan dosis terbaik adalah 2000 g/m2. Kata Kunci : Selada, Bokhasi, Eceng Gondok.The issue of organic farming lately indeed began to grow back more and more people will realize the importance of health and quality of food consumed. In addition to health reasons, organic farming is also believed to be environmentally friendly because it can minimize the use of chemicals in the production process, due to the use of chemical fertilizers continuously with increasing doses it can cause the soil to be loud and disturbed soil nutrient balance.

    Full Text Available Tingkat sosial ekonomi keluarga yang rendah membuat perempuan memiliki peran ganda. Terbatasnya lapangan kerja di pedesaan, ketrampilan yang terbatas dan pendidikan yang rendah menjadikan pemetik teh sebagai pilihan pekerjaan para perempuan. Penelitian ini bertujuan menggambarkan bagaimana pembagian waktu perempuan pemetik teh sebagai efek dari beban ganda dan bagaimana kondisi sosial ekonominya. Kajian ini menggunakan pendekatan kualitatif dengan jenis fenomenologi. Lokasi penelitian ini adalah di desa Keteleng, Batang yang berlokasi di dekat perkebunan teh PT Pagilaran dimana  banyak perempuan desa ini yang menjadi pemetik teh. Metode observasi, wawancara, dan dokumentasi digunakan dalam pengambilan data. Validitas data dilakukan dengan triangulasi sumber dan analisis data dilakukan dengan analisis interpretatif. Penelitian ini menjelaskan bahwa perempuan dengan peran ganda, memiliki waktu domestik dan waktu publik yang berdampak dalam kehidupannya. Hal ini berpengaruh pada kondisi sosial, dimana perempuan pemetik teh tetap memiliki interaksi sosial yang baik dengan keluarga, bahkan memperluas pergaulan dengan masyarakat. Dari segi ekonomi, profesi sebagai perempuan pemetik teh tidak menaikkan kesejahteraan secara signifikan karena rendahnya upah yang diterima. Namun dengan kemandirian ekonominya, perempuan ini memiliki peran yang aktif dalam pengambilan keputusan di keluarga. Tuntutan sosial ekonomi yang dibebankan kepada perempuan ini juga mendorong masyarakat untuk tidak bertindak diskriminatif. Levels of low socioeconomic families lead women to have double roles. Limited employment opportunities in rural areas, limited skills and low education make tea picking as the most possible work for women. The objective of this study is to describe the time division of women tea pickers and their social and economic conditions. The study used a qualitative approach and specifically phenomenology.

    Full Text Available Indonesia merupakan salah satu penghasil teh terbesar di dunia. Menurut data dari Deptan 2010, dengan luas lahan sebesar 127712 ha, Indonesia dapat menghasilkan produktivitas teh sebesar 153971 ton/tahun. Namun sayangnya, selama ini pemanfaatan tanaman teh di Indonesia masih terbatas pada pucuk daunnya saja. Bagian tanaman teh yang memiliki kandungan potensial namun belum dimanfaatkan adalah  biji teh, mengandung 26% saponin, 20-60% minyak dan 11% protein. Saponin merupakan salah satu komponen bioaktif yang telah dimanfaatkan sebagai insektisida pembasmi hama pada tambak udang, bahan baku industri deterjen, shampoo, minuman bir, pembentuk busa pada pemadam kebakaran, dan dapat dimanfaatkan pula sebagai pupuk organik. Pada penelitian ini, saponin biji teh diperoleh melalui ekstraksi biji teh pasca pengepresan menggunakan pelarut IPA 50% secara batch di dalam sebuah ekstraktor berkapasitas 2 L. Pengontakan solvent dengan biji teh dilakukan secara dispersi. Pada penelitian ini, rasio massa pelarut terhadap massa umpan diset 20:1; temperatur divariasikan 25-60 oC, kecepatan pengadukan 100-400 rpm, serta ukuran biji teh divariasikan -40+50 mesh s.d -100+200 mesh. Ekstraksi dilakukan hingga tercapai kesetimbangan. Ekstrak yang diperoleh dipekatkan menggunakan rotavapor vakum pada temperatur di bawah 40oC. Ekstrak pekat saponin kasar yang didapat dimurnikan dengan penambahan eter, etanol dan petroleum eter secara bertahap sehingga diperoleh endapan saponin murni yang kemudian dikeringkan menggunakan tray drier pada temperatur 40oC.

    Full Text Available Perkembangan pertumbuhan kota meningkat sehingga fenomena yang berkaitan dengan sumber daya air semakin meningkat. Pertumbuhan penduduk setiap tahun bertambah menyertai pertumbuhan kota, menjadikan pemanfaatan air tanah semakin meningkat. Fenomena yang terjadi adalah bahwa ketersediaan lahan untuk prosesnya terjadinya resapan air ke dalam tanah semakin berkurang, dimana luasan lahan yang ada sangat tidak mencukupi resapan air ke dalam tanah. Di samping itu, resapan air ke dalam tanah dipengaruhi tingkat permeabilitas dari jenis tanah pada lingkungan daerah sekitar resapan. Akibat dari jumlah resapan air ke dalam tanah yang tidak seimbang dengan jumlah pemakaian air tanah yang digunakan mengakibatkan terjadinya penurunan muka air tanah dengan disertai penurunan lapisan tanah. Bila hal ini terjadi secara terus menerus menjadikan elevasi permukaan tanah akan lebih rendah dari permukaan laut. Untuk mengantisipasi hal tersebut terjadi, maka penelitian ini melakukan kajian tingkat permeabilitas daya resap air untuk macam jenis tanah dengan melakukan tes-tes tanah, sehingga dapat diketahui titik imbang antara jumlah air tanah yang dapat diambil dengan air yang dapat meresap ke dalam tanah. Berdasarkan perhitungan curah hujan didapat bahwa besar curah hujan dalam satu tahun sebesar 54.56 m3/detik dan yang meresap hanya 5.37 m3/detik atau 9.84 %. Hal ini menunjukkan bahwa jenis tanah di sekitar wilayah penelitian berjenis lanau dan clay, sehingga mempunyai angka pori yang kecil. Dengan kondisi tersebut maka wilayah tersebut dapat diprogramkan dengan membuat folder-folder tampungan, sumur-sumur resapan, lubang-lubang biopori dan lainya.

    The vibration-rotation emission spectra for the X2Π ground state and the near infrared emission spectra of the X2Π 1/2- X2Π 3/2 system of the TeH and TeD free radicals have been measured at high resolution using a Fourier transform spectrometer. TeH and TeD were generated in a tube furnace with a DC discharge of a flowing mixture of argon, hydrogen (or deuterium), and tellurium vapor. In the infrared region, for the X2Π 3/2 spin component we observed the 1-0, 2-1, and 3-2 vibrational bands for most of the eight isotopologues of TeH and the 1-0 and 2-1 bands for three isotopologues of TeD. For the X2Π 1/2- X2Π 3/2 transition, we observed the 0-0 and 1-1 bands for TeH and the 0-0, 1-1, and 2-2 bands for TeD. Except for a few lines, the tellurium isotopic shift was not resolved for the X2Π 1/2- X2Π 3/2 transitions of TeH and TeD. Local perturbations with Δ v = 2 between the two spin components of the X2Π state of TeH were found: X2Π 1/2, v = 0 with X2Π 3/2, v = 2; X2Π 1/2, v = 1 with X2Π 3/2, v = 3. The new data were combined with the previous data from the literature and two kinds of fits (Hund's case (a) and Hund's case (c)) were carried out for each of the 10 observed isotopologues: 130TeD, 128TeD, 126TeD, 130TeH, 128TeH, 126TeH, 125TeH, 124TeH, 123TeH, and 122TeH.

    Full Text Available Increasing the reproductive capacity through increasing plant growth and nutrition is one plausible mechanism of resurgence. This research was intended to determine the effect of deltamethrin on plant vigor and nutrition contents. The experiment was carried out outdoor. The treatments tested were deltamethrin (50 ppm, buprofezin (100 ppm, and control (water. Insecticide applications were applied one time (at age 26 d or 50 d and two times (at age 26 and 50 d. Deltamethrin applications as many as two times did not increase the total chlorophyll and the photosynthesis rate, nutrients (total nitrogen, total protein, total sugar, total reducing sugar at aged 26 d, and sucrose, growth (plant height and number of tillers, and yield (number of panicles. However, application of deltamethrin at aged 26 d increased the amount of asparagine. Asparagine is known to be associated with the feeding rate of Nilaparvata lugens stimulation. Therefore, increasing level of asparagine after application of deltamethrin at sublethal concentration was considered as one of the factors that might be involved in the mechanism of N. lugens resurgence. Salah satu mekanisme resurjensi adalah peningkatan reproduksi hama melalui peningkatan nutrisi dan pertumbuhan tanaman. Penelitian ini dimaksudkan untuk melihat pengaruh deltametrin terhadap kandungan nutrisi dan vigor tanaman. Pengujian dilakukan di lapangan. Perlakuan yang diuji adalah deltametrin 50 ppm, buprofezin 100 ppm, dan kontrol (air. Aplikasi insektisida dilakukan satu kali masing-masing pada umur tanaman 26 dan 50 hst dan dua kali pada umur 26 dan 50 hst. Aplikasi deltametrin sebanyak dua kali tidak meningkatkan total klorofil dan laju fotosintesis, nutrisi (total nitrogen, total protein, total gula, total gula reduksi pada 26 hst, dan sukrosa kecuali asparagin, pertumbuhan (tinggi tanaman dan jumlah anakan, dan hasil (jumlah malai tanaman. Oleh karena asparagin berperan sebagai pemacu laju makan Nilaparvata

    Full Text Available ABSTRAK Laju erosi yang terjadi di dataran tinggi Dieng, Jawa Tengah sangat tinggi karena pertanian yang dominan adalah sayuran, dan umumnya petani tidak melaksanakan teknik konservasi tanah dan air secara benar. Karena itu, perlu dilakukan penelitian untuk mencari tindakan konservasi tanah yang memadai agar dapat menekan erosi dan aliran permukaan, kehilangan hara dan meningkatkan penghasilan pada usaha tani kentang (Solanum toberosum L dan kubis (Brassica oleracea l. Penelitian ini bertujuan untuk mengkaji pengaruh tindakan konservasi tanah terhadap aliran permukaan, erosi, kehilangan hara, dan penghasilan sehingga diharapkan teknik konservasi yang sesuai pada usaha tani kentang dan kubis dapat ditemukan. Metode yang digunakan dalam penelitian ini adalah dengan mengukur aliran permukaan dan erosi tiap kejadian hujan mulai bulan Februari hingga Mei 2000 selama satu musim tanam pada plot erosi berukuran 2 x 10 meter dengan kemiringan 34 %. Kehilangan hara tanah ditentukan dengan mengukur kandungan hara sedimen tanah. Penghasilan usaha tani dihitung setelah panen. Penelitian dirancang secara faktorial dalam Rancangan Kelompok Lengkap Teracak (RKLT dengan dua faktor. Faktor pertama adalah usaha tani, yaitu kentang (C1 dan kubis (C2. Faktor kedua adalah teknik konservasi tanah, yaitu guludan memotong kontur (P1 sebagai kontrol, guludan sejajar kontur dan teras-gulud yang di tanami serai (P2, guludan sejajar kontur dengm penutupan mulsa alang-alang (P3, dan guludan sejajar kontur dengan mulsa plastik perak hitam (P4.

Soil can provide ecosystem function through complex interactions between organisms in the soil and the soil itself as soil formation, water filtration, as well as providing useful compounds. However, the soil can be a reservoir of disease in humans. This is because the soil is the recipient of the solid waste that causes contamination of soil that may contain hazardous organic and inorganic materials as well as pathogenic microorganisms. The spread of disease-causing agents through the soil can occur as a result of floods, strong winds or transporting soil from endemic areas to other regions. Pathogens that have caused the role of soil-borne diseases are divided into two groups: Euedaphic Pathogenic Organisms (EPOs and Soil Transmitted Pathogens (STP. Prevention efforts need to avoid the spread of disease from soil to human beings as to conduct remediation of soils contaminated with hazardous chemicals as well as efforts to provide a disinfectant, and sanitary environment to prevent contamination of pathogenic microorganisms in the soil.INDONESIANAbstrakTanah merupakan tempat tinggal bagi keragaman hayati dimana 25% dari spesies bumi tinggal di tanah.

    Full Text Available Setiap saat Indonesia mengalami ancaman bencana alam. Hal ini sudah dibuktikan dengan adanya bencana alam yang beruntun menimpa negara ini. Mulai dari tsunami, gunung meletus, banjir, tanah longsor, dan gempa. Dengan adanya hal-hal semacam ini, terpikirkan bagaimana caranya untuk melakukan pencegahan awal agar dampak kerugian material dan korban yang ditimbulkan dapat lebih diminimalisir. Misalnya saja bencana tanah longsor sering terjadi di Kabupaten Kulon Progo. Hal ini terjadi karena penambangan dan minimnya daerah tangkapan air sehingga menjadi penyebab maraknya kasus-kasus longsor di Kulon Progo baik karena aktivitas penambangan yang dilakukan legal atau ilegal. Khusus daerah yang menjadi sasaran penambangan emas di Yogya adalah Kecamatan Kokap. Sehingga menyebabkan banyak kejadian tanah longsor di daerah tersebut. Dengan kondisi daerah yang sering mengalami bahaya longsor, nampaknya perlu dikembangkan sebuah sistem informasi geografis yang dapat membantu dalam manajemen resiko bencana tanah tanah longsor yang terjadi di Kecamatan Kokap, Kabupaten Kulon Progo. Sehingga nantinya jika sistem ini dapat dikembangkan, dapat membantu melakukan analisis resiko dari dampak bencana tanah longsor di era cyber seperti saat ini. Lokasi yang menjadi titik rawan bencana, diharapkan dapat dideteksi dan hasilnya dapat dianalisis untuk kepentingan lebih lanjut. Hasil dari penelitian ini adalah sudah dapat menghasilkan peta bahaya longsor dalam tiga kategori yaitu tinggi, sedang, dan rendah.   Kata-kata kunci: Tanah Longsor,  Bencana Alam,  Sistem Informasi Geografis.

Trichoderma spp. and Penicillium spp. were cultured in bran, corn meal, and rice straw containing media and applied as inoculum to 2-weeks old seedlings. Application of two fungi isolates effectively induced resistance of chili plants to damping-off disease. Trichoderma spp. and Penicillium spp. were significantly reduced disease incidence by 61.5–100% to 46.2–100%, respectively and disease severity by 50–100% and 30–95.9%, respectively. This experiment showed the potential of Trichoderma spp. and Penicillium spp. as biocontrol agents to control damping-off disease on chili.

Salah satu enzim yang dapat dieksplorasi dari tanah hutan mangrove adalah selulase yang merupakan biokatalisator yang banyak digunakan dalam bidang industri. Tidak seperti pengukuran aktivitas selulase murni atau ekstrak kasar yang berasal dari salah satu sumbernya, pengukuran aktivitas selulase secara langsung dari tanah sering mengalami kesulitan dan banyak faktor yang harus dipelajari. Penelitian ini bertujuan untuk mengetahui pengaruh penambahan toluena dan waktu inkubasi reaksi enzimatis terhadap aktivitas selulase yang terdapat pada tanah hutan mangrove pantai Suwung Bali. Pengukuran aktivitas selulase dilakukan dengan metode CMC (Carboxymethyl Cellulose Assay pada sampel tanah (slurry, pelet, dan supernatan dengan dan tanpa penambahan toluena dengan waktu inkubasi reaksi enzimatis 1 dan 24 jam. Glukosa yang dihasilkan dari reaksi dengan substrat CMC (Carboxymethyl Cellulose dianalisis secara spektrofotometri UV-Vis pada panjang gelombang 540 nm setelah direaksikan dengan asam 3,5-dinitrosalisilat (DNS. Hasil penelitian ini menunjukkan bahwa penambahan antiseptik toluena dan waktu inkubasi reaksi enzimatis berpengaruh terhadap aktivitas selulase tanah hutan mangrove pantai Suwung Bali. Aktivitas selulase tertinggi sebesar 249,26 U/mL diperoleh pada lumpur dengan penambahan toluena dan inkubasi reaksi enzimatis 1 jam.   ABSTRACT: Mangrove soil has high biodiversity and has been well known as potential location for enzymes exploration. One of the enzymes explored from mangrove soil is cellulase which is a biocatalysator commonly used in industries. Unlike the measurement of cellulase activity of pure or crude extract obtained from one source, direct measurement of cellulase activity of the soil often counter many obstacles and many factors are involved that need to be elaborated.

    Full Text Available Air tanah masih merupakan sumber air untuk keperluan sehari-hari bagi penduduk perkotaan, lebih-lebih kota kecil pada umumnya. Sumber daya air menunjukkan gejala penurunan kualitas yang disebabkan oleh dampak berbagai macam kegiatan yang menghasilkan limbah dan sistem sanitasi lingkungan yang kurang baik. Daerah-daerah perkotaan yang terletak di dataran alluvial pantai dapat merupakan daerah yang rawan terhadap pencemaran air tanah. Tiga ibu kota kecamatan, yaitu Kutowinangun dan Prembun, Kabupaten Kebumen dan Kutoarjo Kabupaten Purworejo yang terletak saling berdekatan diteliti untuk mengetahui kualitas air tanah yang merupakan sumber air domestik penduduknya dalam kaitannya dengan kondisi sanitasi lingkungan serta persepsi masyarakat terhadap pencemaran sumber air tersebut. Penelitian ini dilakukan dengan mengadakan pengamatan di lapangan wawancara dengan penduduk serta analisis laboratorium terhadap sampel air tanah yang diambil. Hasil analisis laboratorium menunjukkan gejala kualitas air di tiga kota tersebut sudah memperlihatkan gejala penurunan, walaupun belum sampai melampaui ambang batas baku mutu air Golongan B. Penurunan tersebut terlibat dengan tingginya kadar NO2, SO4, Cl, COD dan bakteri coli. Diperkirakan bahwa tingginya kadar zat tersebut terkait dengan masalah limbah yang dibuang, yang didukung oleh sanitasi lingkungan yang masih belum baik. Kadar NO2 dan NO3 cenderung lebih tinggi di daerah pusat kota yang merupakan pusat aktivitas penduduk, dibandingkan dengan daerah pinggir kota. Limbah dari aktivitas kegiatan penduduk di pusat-pusat pelayanan umum, termasuk juga dari sarana transportasi di jalan raya dapat merupakan sumber pencemar air tanah. Bakteri coli pada umumnya tinggi di ketiga kota yang diteliti, melebihi 2400 MPN/100ml.

The drainage system is dendritic with the main river flowing into the South China Sea. Hydrogeochemical method was used to study groundwater of shallow aquifer characters within the area. Based on water samples analysis collected from the study area, it can be deduced that the cations and anions concentration are good for domestic use except in the southern region which the nitrate concentration is higher (more than 20 mg/l compared to the northern region (relatively zero. The areas that possibly possess nitrate-contaminated groundwater have been mapped along with groundwater flow patterns. The southern and middle part of the study area has an east to west groundwater flow pattern, making it impossible for contaminated water from the southern region to enter the northern area, despite in the northern area has lower elevation.

    The proportion of N which absorbed either from natural source (soil), N-fertilizer or N sub.2-fixing microorganism on sorghum plantation in marginal alang-alang lands that group to inceptisol should be studied in securing the soil fertility. In this experiment, N contribution of those N sources was determined during vegetative stage of sorghum on three subgroup of south sumatera's inceptisols. A greenhouse experiment that arranged in randomized complete block design using 2 factorial split plot was carried out in IPB Bogor from May-December 1998. The observation was focused on partition of N contribution from the soil, N-fertilizer and Pseudomonas putida like(N sub.2-fixing microorganism) on total plant-content 4 and 8 weeks after plantations (WAP). N-partition from those N-sources was done based o A-value method. Sorghum was absorb larger proportion of N from soil(63,36%-48,83% on 4 WAP and 64,58 % on WAP) than from fertilizer and P.putida like on all of the soil subgroups. Soil-N absorption was highest on oxic dystropept. Pseudomonas putida like was not able to subtite soil-N and fertilizer-N in sufficient amount to vigorous plant growth particularly on typica humitropept and typic dystropept. The microorganism was only provide a small amount of N to sorghum on oxic dystropept (23,05-23,95 % on 4 WAP and 15,91-34,44 % on 8WAP). The increment of plant root surface area could be enhance in greater extent of plant-N absorption than N sub.2-fixation. Thus, plantation of marginal tolerant sorghum still need addition of N-fertilizer.

    Synthesis of SiO2 cristobalite powders has been successfully carried out by a coprecipitation method by making use of local silica sands from districts of Tuban and Tanah Laut, Indonesia. Cristobalite is a phase of SiO2 polymorphs which can be used as a composite filler, a coating material, a surface finishing media, and structural ceramics. In the first stage of the synthesis, the as-received sands were processed by a magnetic separation, grinding, and soaking with HCl to increase the purity of silica content. X-ray fluorescence (XRF) spectroscopy showed that the atomic content of Si (excluding oxygen) in both powders reached 95.3 and 97.4%. A coprecipitation process was then performed by dissolving the silica powders in a 7M NaOH solution followed by a titration with 2M HCl to achieve a normal pH and to form a gel. Furthermore, the silica gel is washed, dried and then calcined at a temperature of between 950-1200 °C with a variation of holding time for 1, 4 dan 10 hrs to produce white powders. X-ray diffraction (XRD) data analyses showed that the powder with calcination temperature of 1150 °C for 4 hrs exhibited the highest cristobalite content of up to 95wt%. Its scanning electron microscopy (SEM) image showed that its grain morphology was relatively homogeneous.

    A laboratory physical model study on riverbed filtration (RBeF) was conducted to investigate site suitability of soil from Tanah Merah, Kelantan for RBeF. Soil samples were collected and transported to the Geotechnical Engineering Laboratory, Universiti Sains Malaysia for sieve analysis and hydraulic conductivity tests. A physical model was fabricated with gravel packs laid at the bottom of it to cover the screen and then soil sample were placed above gravel pack for 30 cm depth. River water samples from Lubok Buntar, Kedah were used to simulate the effectiveness of RBeF for turbidity removal. Turbidity readings were tested at the inlet and outlet of the filter with specified flow rate. Results from soil characterization show that the soil samples were classified as poorly graded sand with hydraulic conductivity ranged from 7.95 x 10-3 to 6.61 x 10-2 cm/s. Turbidity removal ranged from 44.91% - 92.75% based on the turbidity of water samples before filtration in the range of 33.1-161 NTU. The turbidity of water samples after RBeF could be enhanced up to 2.53 NTU. River water samples with higher turbidity of more than 160 NTU could only reach 50% or less removal by the physical model. Flow rates of the RBeF were in the range of 0.11-1.61 L/min while flow rates at the inlet were set up between 2-4 L/min. Based on the result of soil classification, Tanah Merah site is suitable for RBeF whereas result from physical model study suggested that 30 cm depth of filter media is not sufficient to be used if river water turbidity is higher.

    Full Text Available ABSTRAK Kasus kebakaran hutan yang terjadi di Provinsi Riau dan beberapa daerah di Indonesia menjadi bencana nasional karena dampak dari kebakaran hutan tersebut menyebabkan kabut asap yang merusak kesehatan, mengganggu aktivitas masyarakat, merusak ekosistem tumbuh-tumbuhan dan hewan, membahayakan penerbangan, protes dari negara tetangga karena adanya kabut asap, dan kerugian-kerugian lainnya. Perambahan hutan juga menyebabkan masyarakat adat dipaksa keluar dari tanah leluhur karena hutan tempat hidup dan mencari penghidupan hangus terbakar. Hal ini adalah kejahatan kemanusiaan luar biasa yang dilakukan oleh para penjarah hutan. Pemberian hak guna usaha atas tanah untuk perkebunan yang mengalihfungsikan kawasan hutan menjadi kawasan perkebunan seharusnya terlebih dahulu mendapat persetujuan dari Kementerian Lingkungan Hidup dan Kehutanan, walaupun hak guna usaha yang dimohonkan berada pada kawasan area penggunaan lain yang dikuasai oleh pemerintah daerah. Pengendalian izin pengelolaan dan pemanfaatan lahan untuk perkebunan yang merambah kawasan hutan dapat dilakukan antara lain: membuat peraturan daerah tentang tata ruang wilayah dengan menetapkan kawasan hutan di dalam tidak boleh dialihfungsikan menjadi kawasan perkebunan atau kawasan lainnya, menetapkan hutan abadi di beberapa wilayah di Indonesia, dan kebijakan moratorium izin-izin usaha perkebunan.

    Full Text Available The large increase in the use of modern agricultural chemicals, including pesticides and fertilizers has made agriculture an important non-point source of soil and groundwater contamination. Nitrogen, heavy metals, and organic associated with pesticides are presumably the most common contaminants introduced into the environment by modern agricultural practices. The present and abundance of the chemical contaminants in the soil and underlying groundwater largely depends on their chemical species as well as the various physical, biological and chemical properties of the soil. Understanding these processes and interactions between the contaminants and soil constituents would be useful in identifying effective techniques to restore the soil and groundwater contaminated by modern agricultural practices and others modern society activities. When the level of these contaminants in the soil are such that the quality of the plants, food crops and the groundwater are being compromised, then remedial actions are necessary. Such remediation could include in situ technologies, including bioremediation or phytoremediation combined as well as agronomic-types approaches. The best strategy in reducing soil contamination is to reduce pollution at the source and to use best management practices, such as adopting the most appropriate land use for a given type of soil contamination. Key words: pesticide, contamination, adsorption, bioremediation

    Full Text Available This paper examines how the legal status of leasing the public land in deal with the State's Right of Controlling is and how the further regulating them in the implementation of regional autonomy is. The used method is a normative legal research with secondary data sources through primary legal materials, secondary and tertiary. The results show that leasing the land that the object is a public land constitutes an action against the law, because the state is in fact not the owner of the land. The state only has the right to control the public land and the only the owner has the right to lease the land. Therefore, there is a smuggling law in case of leasing the public land through enacting the regional regulations that contain the permit to use the public land, that the third parties can use public land but the third party must pay a sum of money.

Orchid viruses are widespread in cultivated orchids, withCymbidium mosaic potexvirus (CymMV being the most prevalent. CymMV high incidence in cultivated orchids has been attributed to the stability and ease of transmission of this virus through cultural practices. CymMV induces floral and foliar necrosis. The virus also reduce plant vigor and lower flower quality, which affect their economic value. The objective of the research is to characterize the virus causing mosaic or chlorotic and necrotic on orchids in West Java. A reverse transcription-polymerase chain reaction (RT- PCR assays using oligonucleotide primers specific to CymMV were also successfully amplified the regions of the coat protein (CP gene of the virus. Analysis by using sodium dodecyl sulphate- polyacrylamide gel electrophoresis (SDS-PAGE revealed that the virus have a major structural protein with an estimated molecular weight of 28 kDa.

    The CRE system, used in radiotherapy, is an attempt at a simple, empirical model predicting the response of tissue to irradiation. The two basic formulae used in the CRE system are given followed by a consideration of a number of variable factors which may influence the CRE values. The Cathetron afterloading radiotherapy device demands a completely different schedule from those to which the CRE system is normally applied. The problem of converting a continuous intracavitary schedule to one of fractionated intracavitary treatment for the Cathetron is considered particularly in relation to the volume effect of continuous radiation and also to the wide variation of dose across the volume. It is concluded that in the present state of knowledge it would be unwise to make confident predictions of Cathetron doses on the basis of empirical descriptions such as the CRE. (U.K.)

To be able to extract an indigo dye substance, the indican glycosides contained in the leaves of the plant is first hydrolyzed into Indigo indoxyl and glucose by using either the dilute mineral acids or enzymes. The indoxyl is then oxidized to indigo. In this experiment, the extraction of the blue dye substance of indigo plant was carried out by method of acidifying. The observations made on the variation of the concentration of hydrochloric acid, the aeration time, the acids, and the type of binding substances. The material used in the experiment included the 2 months old of Indigo leaves, hydrochloric acid, sulfuric acid, sodium hydroxide, sugar, lime, alum and tunjung (Ferrous sulfate. The equipments used in the aeration were beaker glass and the air pump.The process was initiated by soaking the indigo leaves in acid with a specific concentration for 24 hours. The filtrate was then oxidized by flowing the air using the air pump for 12 hours. Then, the sample was applied by immersing the fabric in a solution of the binding substances consisted of Ferrous sulfate, alum, and lime. The experiment results show that higher concentration of indigo was obtained from the longer aeration time. By comparing different type of acids, the extraction using 0.01 M H2SO4 shows better than using HCl in the same concentration. The highest indigo concentration produced by the extraction using 0.01 M H2SO4 was 29.20 ppm, while the highest concentration produced from the extraction using 0.01 M HCl was 26.88 ppm.

    Full Text Available Vegetasi Palestina adalah sekelompok tanaman yang tumbuh di bumi Palestina. Para penyair Palestina, melalui puisinya, mengemukakan beragam vegetasi yang tumbuh di Palestina sehingga menimbulkan permasalahan ragam vegetasi apa saja yang disebut dalam puisi dan apa fungsi penyebutannya? Tujuan penelitian ini adalah mengungkap ragam vegetasi asli Palestina dalam puisi karya penyair Palestina. Teori yang dimanfaatkan adalah teori adab al-muqawamah, yang mengatakan bahwa karya sastra merupakan piranti perlawanan terhadap segala penjajah dalam bentuk kata sehingga karya sastra tersebut dapat menggugah semangat pembacanya untuk berjuang. Hasil penelitian menunjukkan bahwa ragam vegetasi Palestina adalah penanda keberadaan wilayah dan bangsa Palestina yang berarti bahwa ada tanah tempat tanaman itu tumbuh dan ada bangsa yang memanfaatkan tanaman itu dalam kehidupan mereka. Penyebutan ragam vegetasi Palestina itu menjadi simbol perlawanan bangsa Palestina terhadap penjajahan Israel yang menduduki tanah Palestina melalui aneksasi dan kolonialisasi. Puisi perlawanan ini merupakan sebuah upaya untuk membangkitkan kesadaran umat manusia di dunia, khususnya bangsa Palestina, untuk melawan segala bentuk penjajahan di muka bumi. Palestine’s vegetation is a group of plants growing in the Palestine’s soil. The Palestinian poets, through their poetries, explained the variety of plants growing in Palestine. Therefore, the research questions are what kinds of native plant growing in Palestine and why the Palestinian poets explain those plants in their poetries? The analysis theory is adab al-muqawamah meaning that literary work is an instrument to fight all forms of occupation and colonialism by using words to inspire the readers to fight. The result is that Palestine’s plant variety is a symbol of the presence of the region and the Palestinians, which means that there is a land where the plants grow and there is a nation that use the plants in their lives

    1983-10-01

    On September 22, 1970, for the first time an accident simulation experiment with complete failure of the forced core cooling and the nuclear shut-down system was performed in the AVR-reactor: Due to a small heat-up of the fuel the nuclear chain-reaction was interrupted and an overheating of the core and structure was prevented due to the natural heat-convection. On the basis of the meanwhile developed computer-methods and accompanying experimental investigations it is now possible to determine exactly the behaviour of the non actively controlled core of the high temperature reactor, and to understand better the course of the AVR-experiments. On the same basis the potential and the limits of the safety conception realized in the AVR with self-stabilization in the case of accident can be determined. Such a small high temperature reactor as for example the HTR-modul of the KWU, which is characterized by a reliable and simple safety-technique with a minimum of expensive active systems, can be realized using a 2-zone-core up to a unit size of nearly 250 MW(th).

The aim of this study was to determine the influence of Vitamine C and Vitamine E in formulation of green tea extract cream to the stabiliy of EGCG. The green tea extract was obtained from the extraction process by infundation followed by fractination with ethyl acetate as the solvent. The three formulas were compiled in similar composition with the concentration of vitamine C 1% (FI, Vitamine E 1% (FII and there was no Vitamine C and Vitamine E (FIII as a control. The EGCG level was determinated by TLC-densitometry methode. The stability parameter was determinated by calculated of the Q10 of each formula. The result of this study showed that the parameter of t90 of EGCG with Vitamine C 1%, Vitamine E 1% and control addition were 0.0108 hours, 0.0087 hours, 0.0084 hours, respectively. Stability of EGCG in green tea leaf extract cream with addition of the vitamin C 1% was higher than it stability with the addition of vitamin E 1%. The concentration of Vitamin C 1% was the optimum concentration as antioxidant in formulation of green tea extract cream.

    Full Text Available Material models are always required to know the characteristics (physical and mechanical properties of the soil layer at the site by using analysis of geotechnical studies that have been done in the field and in laboratories. Soils such as clay, silty clay and peat show a high degree of compressibility compared to other soils. In oedometer testing, the consolidated clay normally behaves up to ten times softer than the normally consolidated sand. This study aims to determine the soft consolidation behavior of soft clay primers by comparing the results obtained from finite element analysis calculations on Plaxis 2D with analytical calculations and survey measurements. Two different material models were used during finite element calculations, comparing the performance of Soft Soil Model, SSM models to the Mohr-Coulomb Model (MCM model commonly used today. Practical geotechnical analysis of stability of embankment construction is done by using Plaxis 8 computer program, based on Finite Element Method to analyze deformation value and safety factor with construction phase of consolidation.  Keywords: Consolidation, deformation, safety facor, SSM

    The analysis for vertical and horizontal deformation in soft soil carried out by comparing between the data resulted from field measurement and from numerical simulation. Numerical simulation carried out by using Plaxis version 7.0. In this simulation, soft soil and embankment soil were modelled in Mohr-Coulomb model material. The results of the analysis showed that there was an increasement in soft soil shear strength. This condition led to the decreasement in horizontal deformation. The extreme difference in horizontal deformation between field measurement and numerical simulaton caused by the difference assumption used in soil modeling. For instance modulus of elasticity assumption, soil homogeneity assumption, and fixed condition at the bottom edge of inclinometer. Maximum vertical deformation in soft soil occurred under the center of trial embankment. It happened because the highest compression occurred in this area when the maximum height of embankment reached. This condition led to highest burden supported by the soil under the center of trial embankment.

    Full Text Available Recently, the utilization of bamboo is more extensive, but the attention towards its regeneration is not sufficient. The use of stem or branch cuttings are more practical and having more benefits and promising because the cutting materials are more available, easier to gain, cheaper, undamaging the source clump, faster in the taking time, and easier in the clump formation. The common rooting media used is top soil (the fertile part of upper layer soil. Recently, it is quite hard to provide top soil in a large number. Thus, it is important to find an alternative source in order to decrease the use of top soil that is by mixing the top soil media with other materials. The media used were soil media, husk charcoal, and the mixture of soil and husk charcoal (2:1. The branch cuttings used were branches of petung bamboo taken from 2 years old amboo, with 2-3 cm in diameter, and 2 nodus in length. The treatment was done by giving some variations in the soil media, the husk charcoal,and the mixture of soil and huskcharcoal. The mixture of soil and huskcharcoal media gave a significant influencet o the length of sprout variable,but it did not give significant influence to the number of sprout, the length of root, and the percentage of rooting.

    Cherax spp. in Indonesia is not so well known compare to other crustaceans such as penaeids shrimp, the main aquaculture products. Since the 1990’s, the production of cherax post larvae has been intended to supply the hobbyists of ornamental crustaceans.  No data available of how large is the production of cherax in Indonesia, either for food or ornament. To provide evidence that cherax is not a padi eater, an experiment was carried out in an integrated culture with padi in 1 m x 1 m x 0.5 m earthen ponds. The cherax stocked into the ponds are C. quadricarinatus and C. albertisi, at 15 PL-45/m2 of each different pond. The water depth in each pond is maintained at 30—40 cm on the perimeter ditch. The feed, grower penaeids shrimp feed, is given at 3% biomass weight when necessary. The cherax is sampled every 30 days for total and carapace length as well as individual weight. Number and weight of grain produced and numbers of paddy seedling are the variable observed to monitor padi growth. The number of grains and seedling in cherax ponds which is not significantly different (P>0.05 from those in ponds without cherax indicating that cherax is not padi eater. Either C. quadricarinatus or C. albertisi achieved maximum individual weight of 20 g in 90 days rearing period. Both of the cherax are dyke hole maker, but tend to causing seepage. The depth of the hole ranges from 20—80 cm, just enough for the cherax to hide just after moulting.

    Full Text Available http://dx.doi.org/10.17014/ijog.vol4no1.20091Geothermal areas occur mainly in an environment of volcanic/magmatic arc where magma chambers play a role as heat sources. The environment is situated within the convergent plate boundaries. A variety of igneous rocks is associated with this environment ranging from basalt (gabbro to rhyolite (granite but andesite is normally the most abundant igneous rock. The most obvious geothermal indications are exhibited by some surface manifestations comprising hot water seepage, fumaroles, hot spring, geyser, and hydrotermal alteration zones which are being evidences of an active hydrothermal system beneath the surface as a part of volcanism. Despite being a causal factor for alteration of country rocks, most hydrothermal fluids enable to change distribution pattern and content of rare earth elements (REE for instance Ce, Eu, La, Lu, Sm, Nd, and Y particularly during a reaction process. This may have a connection with development of element mobility rates, whilst the characteristics of REE pattern within hydrothermal fluid would have a high variable due to dependency of their original magma source. Considering the important role of hydrothermal fluid in REE mobility development, it is inspired to review the possible relationship of active hydrothermal system and potency of REE distribution pattern in areas of geothermal manifestation.

    Full Text Available Soils are made up of organic and an organic material. The organic soil component contains all the living creatures in the soil and the dead ones in various stages of decomposition. Biological activity in soil helps to recycle nutrients, decompose organic matter making nutrient available for plant uptake, stabilize humus, and form soil particles.The extent of the diversity of microbial in soil is seen to be critical to the maintenance of soil health and quality, as a wide range of microbial is involved in important soil functions. That ecologically managed soils have a greater quantity and diversity of soil microbial. The two main drivers of soil microbial community structure, i.e., plant type and soil type, are thought to exert their function in a complex manner. The fact that in some situations the soil and in others the plant type is the key factor determining soil microbial diversity is related to their complexity of the microbial interactions in soil, including interactions between microbial and soil and microbial and plants.The basic premise of organic soil stewardship is that all plant nutrients are present in the soil by maintaining a biologically active soil environment. The diversity of microbial communities has on ecological function and resilience to disturbances in soil ecosystems. Relationships are often observed between the extent of microbial diversity in soil, soil and plant quality and ecosystem sustainability. Agricultural management can be directed toward maximizing the quality of the soil microbial community in terms of disease suppression, if it is possible to shift soil microbial communities.

    Full Text Available Ground Water Filtration by Natural Zeolit to Reduce Iron and Manganese Levels. In rural areas most people use ground water for their daily purposes. Frequently, the water has high levels of Fe dan Mn. To provide a simple, cheap and reliable apparatus to reduce Fe and Mn, a zeolit column has been designed for filtering ground water. The objective of this experiment was to establish the optimal condition of the filtration. Natural zeolit of Bayah origin was crushed and grounded into small particles of approximately 3 mm in diameter. After washed with distilled water and dried in open air, the particles were then packed in a 4 × 50-cm glass column. The zeolit column was installed vertically, watered with distilled water to compact, and dried. Then 500 mL of ground water sample was poured onto the prepared zeolit column. By adjusting the stopcock, the water samples were filtered off at a flowrate of 16 mL/min. Filtrates werecollected with interval of 30 minutes for 2.5 hours and subjected to Fe and Mn analysis. The experiment was repeated for filtration rates of 14, 12, 10, 8, 6, 4, and 2 mL/min. Fe and Mn concentrations, contact times, and flowrates were converted into scattered-plot graphs of contact times versus concentrations. The graphs show that the optimum condition for Fe and Mn removals were 30-minute contact time and 2-mL/minute flowrate. At this, the Bayah zeolit Fe was reduced for 55% but it was only 40% for Mn in ground water containing 3.6 mg/L Fe and 0.7 mg/L Mn. However, at the optimum condition water debit of the zeolit column was only 2.88 L/day. Quantitatively, with filtration rate of 2 mL/minute, up to 2.5 hours contact time the Fe was only reduced to as much 1.12 mg/L (standard: 1.0 mg/L while theMn reduced to nil. It was concluded that the Bayah zeolit was effective to reduce Fe and Mn in ground water, although reducing capacity for Mn was better than for Fe, whereas the column could not be applied for daily purposes due to its low water debit.
