Dari hasil penelitian didapati median kadar yodium dalam urin bayi kelompok I, II dan III naik mencapai puncaknya pada hari pertama setelah pemberian kapsul yodium masing-masing yaitu 27450 ug/l, 15500 ug/l dan 26000 ug/l. Bila dibandingkan dengan awal pemeriksaan kenaikan ekskresi yodium dalam urin kelompok I, II dan III masing-masing adalah 283 kali, 152 kali dan 245 kali. Yodium dalam urin bayi kelompok I dibandingkan dengan kelompok II diasumsikan tidak sama pada setiap waktu pemeriksaan ternyata cenderung tidak terlalu berbeda. Yodium dalam urin bayi pada hri pertama kelompok II dan kelompok III yang bila dibandingkan dengan ekskresi yodium urin kelompok I menunjukkan bahwa ekskresi kadar yodium urin bayi makin tidak konsisten bila dosis suplemen makin tinggi. Ekskresi yodium dalam urin bayi yang mendapat yodium dosis hanya 100 mg ternyata jumlahnya cenderung sama dengan ekskresi yodium dalam urin ibu yang memperoleh dosis 200 mg, yang menunjukkan adanya perbedaan toleransi penyerapan yodium oleh tubuh bayi dan dewasa. Bayi yang hanya mendapat ASI saja (kelompok II ekskresi yodium dalam urinnya sudah menggambarkan kecukupan perolehan yodium pada bayi hingga hari ke 180. Pada akhir penelitian

    Full Text Available Akreditasi perguruan tinggi oleh BAN-PT merupakan salah satu parameter dalam menentukan mutu  perguruan tinggi serta program studi di Indonesia. Keadaan saat ini menunjukkan bahwa untuk mencapai nilai akreditasi yang sesuai diinginkan maka perguruan tinggi serta program studi harus menyesuaikan kondisi internal mereka sesuai dengan standar yang telah diberikan oleh BAN-PT. Sebagai pertimbangan untuk mencapai standar yang ditentukan oleh BAN-PT, maka diperlukanlah proses evaluasi diri apakah program studi atau perguruan tinggi tersbut sudah memenuhi standar yang ditetapkan oleh BAN-PT. Dalam melaksanakan proses evaluasi diri, diperlukan sumber data yang digunakan sebagai dasar dalam menilai pada suatu kriteria. Pada kebanyakan program studi, semua data tersebar pada sistem informasi dan dokumen fisik yang berbeda sehingga membutuhkan waktu dan usaha yang lebih untuk mengintegrasikan hingga menilainya. Sehingga diperlukan sebuah sistem yang mampu mengambil dan menampilkan hasil evaluasi secara visual secara otomatis dengan lebih hemat waktu dan usaha. Salah satu bentuk visualisasi yang dapat menggambarkannya adalah dashboard.  Melalui dashboard, pihak internal program studi dapat mengetahui posisi penilaian mereka pada periode tertentu dan mampu memperbaikinya jika kurang dari target yang ditetapkan oleh standar.

    Full Text Available Fasilitas sisi udara merupakan fasilitas pergerakan pesawat. Fasilitas ini harus memenuhi kekuatan struktur untuk melayani pergerakan pesawat-pesawat yang beroperasi sesuai dengan perencanaan. Tujuan dari penyusunan makalah ini adalah untuk menganalisis apakah perkerasan fasilitas sisi udara di Bandar Udara Juanda saat ini sudah memenuhi batas PCN yang dipersyaratkan atau belum. Analisis dilakukan dengan cara mengevaluasi kekuatan perkerasan runway, taxiway, dan apron eksisting menggunakan metode perbandingan PCN–ACN yang didapat dari pabrik pembuat pesawat, perhitungan dengan software COMFAA dan perhitungan dari Canadian Department of Transportation. Data yang digunakan adalah data pergerakan pesawat termasuk jumlah pergerakan tahunan dan tipe pesawat. Data kekuatan perkerasan sisi udara diperlukan untuk proses analisis. Hasil dari evaluasi menunjukkan B773 memiliki nilai ACN yang melebihi nilai PCN sebesar 50% untuk apron dan 25% untuk runway/taxiway. Besar kelebihan nilai ACN ini tidak mempengaruhi kekuatan struktural karena frekuensi pergerakan yang hanya 45 pergerakan per tahun. Dampak lain adalah pada fungsional perkerasan yang menunjukkan berkurangnya kekesatan runway dari hasil sand patch test.

    Full Text Available Shh, Respect Freedom of Speech: The Reasons Why Ngugi wa Thiong’o and Ismail Kadare Have Not Been Awarded the Nobel Prize Abstract The terrorist attack on the satirical French magazine, Charlie Hebdo, at the beginning of this year, intensified the unremitting debate over the right to freedom of speech and expression, as well as its limitations. Nonetheless, it was almost unanimously agreed that the human right to express personal beliefs, regardless of the fact that they could be in deep disagreement with or even insulting towards the values of certain individuals, groups, or worldviews, should be defended and promoted by the whole human community. It goes without saying that the role of intellectuals and, especially, that of the academia, in promoting tolerance, diversity, and dialogue is essential. However, this does not seem to have been one of the criteria on which the Swedish Academy based its choices, over the past years, for the awarding of the Noble Prize in Literature. Focusing on the literary contributions of Ngugi wa Thiong’o and Ismail Kadare, two repeated nominees for the Noble Prize, this paper will attempt to shed light on the reasons why these two “heroes” of free speech and representation have not been awarded the prestigious prize.

    Frame Partial Denture as a Supportive Therapy for Periodontal Health. Partial denture is very important in maintaining periodontal health and maintaining the stability of the remaining teeth. The fabrication of denture is an important phase in comprehensive periodontal health therapy, so as to maintain the periodontal health. Removable partial dentures should be designed to reduce the accumulation of food residue and plaque on the teeth and gingival edge of the abutment. The selection of metallic materials as denture in case of periodontal compromise can help in preventing tooth movement and maintain the position of the teeth after periodontal treatment because the nature of metal is more rigid when compared with other materials, so that the success of the treatment can be achieved. Making good metal framework denture and good cooperation between all members of the medical team in handling the case will result in a successful treatment. The aim of the study is to enrich the knowledge for periodontists and prosthodontists in using metal removable prothesis in compromised periodontal patients. Providing information and educating patients in maintaining the cleanliness of denture and mouth are also an important factor that determines the success of the manufacture of dentures.

Pada dasarnya uji klinik memastikan efektivitas, keamanan dan gambaran efek samping yang sering timbul pada manusia akibat pemberian suatu obat. Bila uji klinik tidak dilakukan maka dapat terjadi malapetaka pada banyak orang bila langsung dipakai secara umum seperti pernah terjadi dengan talidomid (1959-1962 dan obat kontrasepsi pria (gosipol di Cina. Setiap obat yang ditemukan melalui eksperimen in vitro atau hewan coba tidak terjamin bahwa khasiatnya benar-benar akan terlihat pada penderita. Pengujian pada manusia sendirilah yang dapat “menjamin” apakah hasil in vitro atau hewan sama dengan manusia.Uji klinik terdiri dari 4 fase, yaitu uji klinik fase I.Uji klinik fase II, uji klinik fase III dan uji klinik fase IV. Uji klinik fase I dilakukan pada manusia sehat, bertujuan untuk menentukan dosis tunggal yang dapat diterima, Uji klinik fase II, dilakukan pada 100-200 orang penderita untuk melihat apakah efek farmakologik yang tampak pada fase I berguna atau tidak untuk pengobatan. Uji klinik fase III dilakukan pada sekitar 500 penderita yang bertujuan untuk memastikan bahwa suatu obat baru benar-benar berkhasiat. Uji klinik fase IV merupakan pengamatan terhadap obat yang telah dipasarkan. Fase ini bertujuan menentukan pola penggunaan obat di masyarakat serta pola efektifitas dan keamanannya pada penggunaan yang sebenarnya.Uji klinik yang baik dilakukan dengan prosedur yang sudah digariskan dan komponen- komponennya disiapkan dengan matang sehingga hasilnya betul- betul dapat dimanfaatkan sebagai acuan pengobatan.Kata kunci : Khasiat- keamanan- uji klinikAbstractClinical trials is a new drug efficacy testing in humans, which previously preceded by testing on animals or pre-clinical testing.

Phase I clinical trial, performed on healthy humans, aims to determine an acceptable single-dose, phase II clinical trial, performed on 100-200 patiens to see whether the pharmacologic effects seen in Phase I is useful or not for treatment. Phase III clinical trials conducted on about 500 patients which aims to ensure that a new drug is really efficacy. Phase IV clinical trial is an observation of the drug has been marketed. This phase aims to determine patterns of drug use in society and patterns of effectiveness and safety in actual use.Good clinical trials conducted with procedures that have been outlined and its components prepared and thus the results can actually be used as a reference treatment.

    Full Text Available Effluent that is produce by the electroplating industry, especially nickel chrome plating, contains chromemetal that is carcinogenic. The toxicities from chrome are caused by its ability to dissolve and it’s mobilityin the environment. An alternative treatment to reduce chrome is called fitoremediasi which uses plants asits indicator; in this case we use water hyacinth.At the preface experiment, we tried to plant mature water hyacinth in electroplating waste. First we tried toplant in 100% waste water in witch we repeated it 3 times. At the 3rd week; day 18; the plants becameyellowish and became wilted. Knowing this fact, we applied the time for our experiment the we were goingto executed, with assuming at the 18th day the plants will become wilted as an indicator that the waterhyacinth are saturated in adsorbing chrome as the heavy metal pollutant. This became the parameter indesigning the time treatment for the plant zone, 4 until 15 days.The treatment was done by making variation in the amount of plants that are planted, which was 0 plants(as the control, 1 plant, 2 plants, 3 plants, and 4 plants; with 3 times repeating at each stage. The result ofthis experiment after 18 days shows the chrome concentration and the efficiently in decreasing theconcentration on each stage. The highest efficiently for each plant was the treatment by 1 plant only. Thehighest efficiently in decreasing the concentration was 78,95% ad it was done by the treatment with 4plants. To get chrom concentration which is fill with the standard, we can add more water hyacinth into thewaste with the balance equivalent or we need the lower beginning concentration.

The size of the tannin content received by the body depends on the way of processing tea before drinking. The longer the brewing time for tea bags will make the content of tannins in higher beverage. So that the problem statements in research is whether there is a long brewing tea influence on levels of tannins? The purpose of this study was to investigate the influence of long brewing on levels of tannins in tea bags. This type of research is experimental. The sample in this study is a tea bag that is often consumed by people who sold in Superindo Mulyosari area. The samples used in this study were 30 tea bags the size of 2 grams divided into 6 treatments each - each consisting of 4 repetitions. Variable in this study is the independent variable while the dependent variable brewing long that tannin levels From the results of tannin levels based brewing long known that the average - average levels of tannins with brewing time 2 minutes, 4 minutes, 6 minutes, 8 minutes, 10 minutes and 12 minutes respectively were 0.0184%, 0.0398%, 0.0546%, 0.0936%, 0.1568% and 0.1578%.

    Full Text Available Severe pre-eclampsia is the second highest cause of maternal mortality. Free radicals that stimulate heat shock protein 90 (HSP 90 are believed to determine severe pre-eclampsia. HSP90 is an important protein that helps the establishment and maintenance of other proteins. It also increases the life time of cells after various pathological conditions (chaperone function. The chaperone function is the adaptation key factor to endogenous stress in tissues. By recognizing HSP90 level in early detection of severe pre-eclampsia, prevention and management can be started early. This study aimed to prove that the HSP90 level in pregnancy with severe pre-eclampsia is higher than normal pregnancy. This was a quantitative study using cross sectional approach by testing the HSP90 level. The study was conducted during the period of September to November 2013, at the Obstetrics and Gynecological Unit, Moewardi Hospital Surakarta and Prodia Laboratory Jakarta. The number of subjects was 30 patients, consisting of 15 normal pregnant mothers and 15 pregnant mothers with pre-eclampsia . The calculation of serum HSP90 level was conducted using enzyme-linked immunosorbent assay (ELISA. Data were analyzed using t-test using SPSS for Windows version 17 for Windows. The mean of HSP90 in the severe pre-eclampsia group was 131.91±26.66 while the mean in the normal pregnancy group was 80.28±13.39 with p=0.00 (p<0.05. Level of HSP90 serum in severe pre-eclampsia is higher than in normal pregnancy, due to the occurrence of oxidative stress in severe pre-eclampsia

Inrendang making process, a meat is cooked under long time heat with a large amount of variety spices.Kalio, a rendang similar dishes,is cooked with a shorter heating time and less of spices. Kalio has a few sauce while rendang has no sauce. Long time heating in cooking processmay cause maillard reactionin rendang and kalio. One effect of maillard reaction is lowering the availability of amino acids, consequently could reduce the protein content qualities. To assess the protein nutritional values of rendang and kalio, an in vivo study was conducted using albino rats as animal models. The result showed that cooking process did not confirm any significant differences on feed conversion efficiency, protein efficiency ratio, net protein ratio (NPR, true protein digestibility and biological value (p>0.05between rendang and kalio, however asignificant difference on net protein utilization (p<0.05 was found.Keywords: rendang, kalio, protein qualityABSTRAKRendang merupakan salah satu masakan tradisional Indonesia asal Sumatera Barat yang sudah mendunia. Pada proses pembuatannya, rendang dimasak dalam jangka waktu yang lama dengan menggunakan beragam bumbu dalam jumlah banyak. Kalio merupakan jenis masakan yang hampir sama dengan rendang, akan tetapi dimasak dengan waktu lebih singkat, dan menggunakan bumbu yang lebih sedikit. Pada kalio masih terdapat sedikit kuah, sedangkan pada rendang sudah tidak terdapat kuah, atau kering. Pemanasan dalam jangka waktu lama pada proses pemasakan kedua jenis hidangan ini, menyebabkan terjadinya reaksi maillard pada rendang ataupun kalio. Salah satu dampak reaksi maillard adalah menurunnya ketersediaan asam-asam amino, sehingga mengakibatkan penurunan kualitas protein. Untuk membuktikan hal tersebut, dilakukan analisis kualitas protein rendang dan kalio secara in vivo dengan menggunakan tikus albino sebagai hewan model.

    Full Text Available This research aimed to discuss the parking policy in Semarang which has not been managed properly. In general, the condition of parking management in Semarang is still quite bad. This is indicated by the poor parking service provided and the low amount of parking retribution every year. During 2011 - 2012 for example, the revenue realization of parking retribution was only about 1.3 billion rupiah from the target of about 4.8 billion rupiah, or only about 25 percent of the target set. This condition was worsened by parking services that were very uncomfortable and unsatisfactory. This research used a descriptive method with a qualitative approach. The author used secondary data which was obtained from PATTIRO Kota Semarang. This study focuses on parking policy in Semarang by describing the condition of parking management which already exists and discussing revenue gap between target and realization from parking retribution. By analizing data, the authors argued that the main problem of parking management in Semarang is the weak implementation of the Regional Regulation on parking retribution. In addition, the parking policy managed by local Government tends to be unsatisfactory, potentially leaky, and the realization is far from the target set. Therefore, in order to solve the parking problems, the local Government must seriously implement the local regulation of parking retribution and rearrange the parking management which already exists.

Peningkatan kontras dengan meningkatkan perbedaan kecerahan antara obyek dan latar belakang benda dapat memberikan perbedaan informasi yang didapat. Manipulasi kontras dilakukan sebagai peregangan kontras dengan meningkatkan perbedaan kecerahan yang seragam di seluruh dynamic range dari citra.   Dari informasi MTF suatu lensa dan perubahan nilai kontras dengan teknik contrast stretching akan menghasilkan sebuah citra dengan peningkatan kualitas sehingga interpretasi citra tersebut lebih fleksibel untuk menghasilkan informasi yang dibutuhkan.Sebuah citra digital harusnya memiliki tingkat kecerahan yang optimum yaitu mulai dari gelap  sampai terang. Hal tersebut ditandai dengan nilai digital number citra yang memiliki range 0 – 225. Dari hasil penelitian penggunaan kamera Canon Powershot A2200 menunjukkan perubahan digital number pada citra hasil perekaman yang sebelumnya memiliki rentang 10 - 255 untuk band merah dan biru menjadi  0 – 255 pada semua band dengan peningkatan nilai mean untuk tiap – tiap band : Red(115.2 menjadi 127.1, Green(111.4 menjadi 126.9 dan Blue(93.9 menjadi 129.5. Peningkatan nilai digital number tersebut menunjukkan bahwa adanya peningkatan kecerahan dari citra sebelumnya sehingga daerah yang sebelumnya gelap menjadi relatif terang.

    Full Text Available Small and Medium Enterprises (SME brass foundry in Ngawen Sidokarto, District of Godean, Sleman, Yogyakarta mostly produced cow necklace accessories (klonthong and jathilan accessories (klinthing. Te industry and business management are arranged within the scope of family. Te products are relatively low in quality and its market share is limited and tend to be traditional. Tis condition is caused by the weak knowledge of the management and the method of casting metals and metal science. Brass casting methode, that was used at IKM partner, is casting with mold of sand or soil. Tis process requires the making process of sand molds, that is removed afer the brass solidify. For large quantities products, this process is inefcient and takes a long time. It would require a more efcient and faster method in the production process. Method of sand casting and ceramics have been used by SMEs cast brass in Yogyakarta, however it  has many disadvantages in terms of increased productivity and quality as well as the expansion of product applications. Te permanent mold casting of iron is a casting method which has many advantages over other methods, but the use for SMEs has not been applied in the SME of cast brass. Te permanen mold casting methods was introduced to SME partners. Tis replaces the sand mold materials and molding sand. It is expected the casting process is faster because the mold can be used for a large number of products. Te results show that the application of the technology results in products with precision and consistent in shape and size. Community Service of UGM with Appropriate Technology has also collaborated with  Industry and Trade service of Yogyakarta donation of production machinery for making permanent mold. It can be concluded that the application of permanen mold in the brass foundry industry improve the product precision and the speed of produsction.

    Full Text Available http://dx.doi.org/10.17014/ijog.vol1no1.20064aWhen tailing of a mining activity is discharged into either landscape or river body, the pollutan element wastes are possible to disperse within those areas and may cause pollution on environment. The environment pollution hazards of arsenic (As, mercury (Hg, lead (Pb and cadmium (Cd probably occurred if tailing with the content of those elements is not handled properly. Particularly in the tropical regions, higher rates of chemical weathering and bio-chemical activity will contribute a rapid mobilization of the most potentially toxic elements.One of adverse health effects from arsenic to human life is in the case of arsenic-contained drinking waters exceed the threshold limit value. As a result, it will create chronic symptoms of toxicity within the human body such as gastro-intestinal irritation, nerve damage and tissue wastage. Tailing originated from amalgamation processing of gold ore enables its mercury waste to disperse in the vicinity of mining area and may form environment pollution by either organic or inorganic mercury. The pollution would be more hazardous to human health if mercury element in the water body transform biochemically into a compound of methylmercury. There is a variety of mechanisms by micro-organism which can bring about the formation of the very toxic methylmercury species, particularly with regard to its uptake by fish. Effects to the human health from the organic mercury include the blood-brain barrier and upsetting the metabolism of the nervous system. Whilst the main toxic effect of inorganic mercury is disruption the functions of kidneys and liver within human body. Most mining activity of base metal may discharge tailing with a significant lead (Pb content. Lead is a cumulative poison, hence absorbing this element by human body with particularly exceeding its threshold limit value will bind strongly to a large number of molecules such as amino acids, haemoglobin, many enzymes, RNA and DNA. Then it will bring into disruption of many metabolic pathways, blood hypertension, hyperactivity and brain damage. Problems of cadmium could arise from a lead-zinc mining and smelting operation, from where pollution due to cadmium-contained tailing with additional aerial pollution associates with cadmium-contained fumes and particles. The toxic effects of cadmium to human health are suffering from lumbago-type pains, bone damage with multiple fractures of the softened bones and kidney failure.

    Full Text Available THE EFFECT OF IODIZED SALT INTERVENTION ON THYROXINE OF CHILDBEARING AGE MOTHERS IN ENDEMIC IODINE DEFICIENCY AREA The national evaluation on implementation of Iodized salt indicate an excess dietary intakes of iodine. It is a consequence of the correction of iodine deficiency. However there is no confirmation of the adverse effect to the excess in Indonesia. Our aim is to elaborate whether the excess of iodine consumption affect serum thyroxine. We supplied 50-ppm iodized salt to 82 mothers at childbearing age’s family every two weeks for three months. We suggest the mothers used the supplied iodized salt for family consumption only and not used the salt for any other purposes such as cattle feeding. Mother’s blood drawn before and after intervention. Urine iodine exretion (UIE were collected from school age children of participant family. The study revealed that three month-iodized salt intervention increased median UIE by 18.4 % and serum thyroxine level by 36.5 %. The number of children being at risk for hyperthyroidism were constributed from normal and deficit range level at initial study by 62,5 % and 41.7 % respectively. The number of mothers being thyroxine excess were 22.2 and 22.7 % respectively. We conclude that the level of iodine consentration in salt at 50 ppm is high and suggest that consentration should be lowered. Keywords: EIU, at risk for hyperthyroidism, thyroid hormone excess.mother at child bearing age.
