    Full Text Available Saat ini, penyimpanan energi berbasis baterai memiliki peranan penting di berbagai sistem kelistrikan,  mulai dari perangkat elektronik sampai dengan sistem berskala besar, termasuk mobil listrik. Baterai Lithium Ion saat ini menjadi paling unggul diantara teknologi baterai yang lain karena kepadatan energinya yang besar. Pada umumnya, sel tegangan dihubungkan seri dalam bentuk string untuk mencapai tegangan sistem yang dibutuhkan. Sel Lithium Ion yang terhubung seri memberikan masalah teknis berupa ketidakseimbangan tegangan yang ada diantara sel yang terjadi karena performa setiap sel yang unik. Hal tersebut akan mengurangi kapasitas yang tersedia pada baterai sehingga  lama waktu operasi akan berkurang dan mengakibatkan percepatan degradasi sel karena overcharge atau overdishcharge. Equalizer tegangan sel menggunakan flyback konverter menggunakan arsitektur cell-to-string, dimana  energi pada sel yang memiliki tegangan lebih tinggi akan ditransfer ke string untuk menyeimbangkan tegangan sel.

    Full Text Available Berdasarkan standar IEEE 1584-2002 yang mengatur tentang analisa bahaya busur api (arc-flash pada sistem tegangan rendah dan menengah, pengguna dapat dengan mudah menentukan batas keamanan untuk para pekerja. Namun, perlu diperhatikan bahwa standar yang ada diperoleh dari hasil pengukuran insiden energi busur api pada kondisi tertentu dan dikombinasikan dengan teori. Menurut rekomendasi standar IEEE, perhitungan arus hubung singkat selalu memperhatikan kontribusi arus gangguan dari generator, motor induksi dan sinkron. Besar kecilnya energi arc-flash dapat ditentukan dari beberapa sudut pandang. Diantaranya ialah nilai energi arc-flash akan besar apabila dihitung dengan menggunakan arus bolted three-phase fault, sedangkan dari sudut pandang arc-clearing time yang didapat dari waktu dimana arus gangguan saat itu terjadi akan menghasilkan nilai energi busur api yang lebih rendah. Hal ini memunculkan metode perhitungan modifikasi yang didasarkan pada perhitungan kontribusi arus hubung singkat dan waktu pemadaman busur api (arc-clearing time sehingga besar energi busur api yang dihasilkan lebih rendah dari perhitungan standar IEEE 1584-2002. Hal tersebut dapat dijadikan sebagai acuan untuk perbaikan sistem pengaman.

    Smoking among adolescent is a public health concern in Malaysia. Multiple studies on smoking prevalence and its related factors have been conducted in Malaysia, however, they were specific to either urban or rural areas alone. Studies in mixed settlement areas (urban, rural, land development area) had not been intensively investigated. This study reports the prevalence, demographic and factors related to smoking amongst form four students in the district of Kota Tinggi, Johor. A cross-sectional study of 16-year old secondary school students in Kota Tinggi district was conducted using two-stage stratified, proportionate sampling in July 2005. The study instrument used was a validated structured questionnaire on smoking and its related factors. Smoking prevalence was found to be 29.7%. More than 50% of male students were smokers. Prevalence was highest in FELDA (Federal Land Development Authority) settlement areas. Smoking was associated with having a brother or friend who smokes and poor academic performance. The study revealed that smoking prevalence was high, especially among male students in land development schemes. This situation will contribute to high smoking-related health problems in the future if proper preventive measures are not taken accordingly.

    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.

    2018-03-01

    Full Text Available Pembelajaran fisika sampai saat ini lebih mengutamakan penilaian hasil belajar tanpa menilai proses pembelajarannya. Selain itu, sistem penilaian prestasi siswa lebih banyak didasarkan melalui tes-tes yang sifatnya menguji kemampuan kognitif tingkat rendah sehingga menyebabkan rendahnya prestasi siswa Indonesia di bidang sains khususnya fisika yang masih di bawah rata-rata internasional. Kemampuan kognitif tingkat rendah ini belum melibatkan proses analisis siswa. Untuk melibatkan proses analisis siswa diperlukan tes yang menguji kemampuan kognitif tingkat tinggi. Namun untuk memberikan tes yang dapat menguji kemampuan kognitif tingkat tinggi diperlukan proses pembelajaran yang dapat memberikan pengalaman langsung pada siswa. Pembelajaran yang melatih keterampilan berpikir tingkat tinggi dapat dikembangkan melalui pembelajaran langsung dengan tujuan agar siswa dapat memperoleh ingatan dalam jangka panjang dan siswa juga dapat mengonstruk pengetahuannya sendiri, tetapi kenyataannya secara umum pembelajaran fisika didominasi dengan metode ceramah. Aktivitas siswa hanya terbatas pada mendengarkan, mencatat, menjawab pertanyaan bila guru memberikan pertanyaan, maka proses pembelajaran tersebut jelas tidak mendorong siswa untuk berpikir kritis dan kreatif dalam beraktivitas. Salah satu model pembelajaran yang sesuai dengan permasalahan tersebut adalah model pembelajaran tipe Think-Pair-Share (TPS berbasis pemecahan masalah. Model ini dapat mengembangkan keterampilan berpikir tingkat tinggi pada diri siswa, membuat siswa terlibat langsung dalam proses pembelajaran sehingga siswa belajar konstruktif tidak bersifat hapalan dan melatih siswa untuk melakukan proses berpikir dan mengungkapkan pendapat dalam memecahkan permasalahan yang ada. Dengan adanya model pembelajaran tersebut diharapkan dapat meningkatkan keterampilan berpikir tingkat tinggi siswa yang meliputi keterampilan menganalisis, mengevaluasi, dan menciptakan seiring dengan meningkatnya

    Full Text Available Penggunaan bahan bakar tingkat muat tinggi dapat memperpanjang siklus operasi reaktor sampai 40 hari. Telah dilakukan perancangan konversi teras dari silisida tingkat muat rendah menuju tingkat muat tinggi. Manajemen konversi teras dari teras silisida tingkat muat 2,96 gU/cm3 menuju teras silisida 4,8 gU/cm3 dilakukan secara bertahap dengan melakukan perhitungan manajemen bahan bakar dalam teras yang menggunakan paket program perhitungan 2 dimensi Batan-FUEL. Penggantian bahan bakar di teras menggunakan pola pergeseran bahan bakar 5/1 yaitu setiap awal siklus terjadi penggantian 5 buah elemen bahan bakar standar dan 1 buah elemen bahan bakar kendali. Dengan mempertahankan konfigurasi teras yang sudah ada, konversi teras dapat dilakukan melalui simulasi teras campuran 2,96 gU/cm3 - 4,8 gU/cm3 dengan memperhatikan batasan keselamatan reaktor yang dipersyaratkan. Oleh karena itu tujuan dari penelitian ini adalah untuk merancang teras campuran yang akan menghasilkan parameter neutronik yang aman pada teras penuh pertama silisida tingkat muat tinggi. Dalam perancangan ini digunakan batang kendali pengaman untuk menambah margin padam yang berkurang akibat pemuatan bahan bakar tingkat muat tinggi. Hasil analisis menunjukkan bahwa konversi teras silisida tingkat muat 2,96 gU/cm3 menuju 4,8 gU/cm3 dapat dilakukan melalui teras campuran tidak langsung dalam 2 tahap yaitu konversi teras silisida 2,96 gU/cm3 - 3,55 gU/cm3 dan konversi teras silisida 3,55 gU/cm3 - 4,8 gU/cm3 dengan performa yang baik. Keuntungan utama dari penggunaan bahan bakar silisida tingkat muat tinggi 4,8 gU/cm3 dibanding teras silisida tingkat muat rendah 2,96 gU/cm3 pada teras RSG-GAS ialah bahwa panjang siklus operasi dapat lebih panjang 18 hari sehingga dapat menghemat penggunaan bahan bakar.

Sebagaimana diketahui bahwa proses perekaman citra satelit diliput dari wahana (satelit yang bergerak di atas permukaan bumi pada ketinggian ratusan kilometer, sehingga menyebabkan citra satelit memiliki distorsi geometrik. Untuk mengurangi pengaruh distorsi geometrik objek pada citra, dilakukan koreksi geometrik dengan cara ortorektifikasi. Pleiades merupakan satelit penghasil citra satelit resolusi tinggi yang dibuat oleh perusahaan Airbus Defence & Space. Citra satelit yang dihasilkan memiliki resolusi spasial 0,5 meter Sebagai acuan bagi kegiatan pemanfaatan ruang yang lebih rinci dari kegiatan pemanfaatan ruang yang diatur dalam Rencana Tata Ruang Wilayah (RTRW, maka dibuat Rencana Detail Tata Ruang (RDTR dengan peta skala 1:5.000 yang telah diatur oleh Badan Informasi Geospasial. Dalam proses ortorektifikasi citra satelit untuk pembuatan peta skala 1 : 5000 ini, digunakan titik kontrol tanah atau Ground Control Point (GCP untuk proses koreksi geometris dan data Digital Elevation Model (DEM. Pada penelitian ini dilakukan proses ortorektifikasi dengan metode polinomial Rational Function menggunakan 21 GCP pada polinomial orde 2. Didapat nilai RMS Error jarak pada citra hasil ortorektifikasi sebesar 0.419 meter, tetapi masih masuk toleransi untuk pembuatan peta skala 1:5000 pada uji statistik T-Test dengan α=5% & α=10%. Didapat juga nilai pixel citra sebelum ortorektifikasi sebesar 0,543592 meter sedangkan setelah ortorektifikasi sebesar 0,500032 meter. Yang berarti, setelah proses ortorektifikasi, nilai pixel sesuai dengan resolusi spasial citra ≈ 0,5 meter.

    Marine sponges were known to produce novel bioactive compounds that have anti-bacterial, anti-viral, anti-cancer and anti-fungal activities. Most of the bioactive compounds were secreted from the bacteria that lives on the sponges. The bacterial communities also produced biofilm, toxin or biosurfactant that protect the sponges from disease or in-coming predator. In this study, twenty nine marine bacteria with swarming motility characteristic was isolated from 2 different sponge samples collected in Pulau Tinggi These isolates were grown and their genome were extracted for molecular identification using the 16S rRNA approach. Sequence comparison using BLASTn and multiple alignments using MEGA4 was performed to produce a phylogenetic tree. The phylogenetic tree revealed that 20 of the isolates were grouped under α-Proteobacteria that comprised of 19 isolates in the Vibrionaceae family and one belongs to Aeromonadaceae family. Furthermore, six isolates from Actinobacteria family and three isolates from Firmicutes were also detected. The swarming characteristic indicates the possible production of biosurfactant.

    Smoking among adolescents has been linked to a variety of adverse and long term health consequences. "Susceptibility to smoking" or the lack of cognitive commitment to abstain from smoking is an important predictor of adolescent smoking. In 2008, we conducted a study to determine the psycho-sociological factors associated with susceptibility to smoking among secondary school students in the district of Kota Tinggi, Johor. Two thousand seven hundred students were randomly selected by proportional stratified sampling. Analyses on 1,736 non-smoking students revealed that prevalence of adolescents susceptible to smoking was 16.3%. Male gender (aOR=2.05, 95%CI= 1.23-3.39), poor academic achievement (aOR 1.60, 95%CI 1.05-2.44), ever-smoker (aOR 2.17, 95%CI 1.37-3.44) and having a smoking friend (aOR 1.76, 95%CI 1.10-2.83) were associated with susceptibility to smoking, while having the perception that smoking prohibition in school was strictly enforced (aOR 0.55, 95%CI 0.32-0.94), and had never seen friends smoking in a school compound (aOR 0.59, 95%CI 0.37-0.96) were considered protective factors These results indicate that follow-up programmes need to capitalise on the modifiable factors related to susceptibility to smoking by getting all stakeholders to be actively involved to stamp out smoking initiation among adolescents.

    This study was carried out to determine the water quality index at the Pelepah Kanan River, Kota Tinggi, Johor. Six stations were chosen from different part of the river from upstream to downstream to represent the water quality index along this river. Three replicates of samples were taken from each station. Samples were collected in two different seasons namely dry season (July) and rainy season (December) 2007. In-situ physico-chemical measurements included temperature, ph, dissolved oxygen and conductivity. Physico-chemical parameters determined in the laboratory were turbidity, total suspended solid (TSS), biochemical oxygen demand (BOD), chemical oxygen demand (COD) and ammonia nitrogen (NH3-N). According to the Interim National Water Quality Standards (INWQS), results showed that all sampling stations along the Pelepah Kanan River in July fall in Class I-II for physical and chemical parameters except for dissolved oxygen and pH which was in Class I-II. The results obtained in December also showed that all sampling stations fall in Class I for physical and chemical parameters except for pH which was in Class III. Correlation test showed that some physico- chemical parameters have significant correlation with each other. Water Quality Index (WQI) analysis showed that the mean WQI value for the month of July is 96.88 (Class I) while for December, the WQI value deteriorated to 84.03 (Class II). According to the calculated values of WQI and comparison with INWQS, the index of water quality in Pelepah Kanan River is in the clean category and is not affected by pollution neither anthropogenic activities nor natural pollution.

    Intention to smoke is a valid and reliable factor for predicting future smoking habits among adolescents. This factor, however, has received inadequate attention in Malaysia. The present paper elaborates the prevalence and factors associated with intent to initiate or to cease smoking, among adolescent nonsmokers and smokers in Kota Tinggi, Johor, Malaysia. A total of 2,300 secondary school students aged 13-16 years were selected through a two-stage stratified sampling method. A set of standardized questionnaires was used to assess the smoking behavior among adolescents and the inter-personal and intra-personal factors associated with smoking intention (intention to initiate smoking or to cease smoking). Multivariable logistic regression was used to identify factors related to smoking intention. The prevalence of intention to smoke in the future or to cease smoking among non- smoking adolescents and current smokers were 10.7% and 61.7% respectively. Having friends who smoke, social influence, and poor knowledge about the ill effects on health due to smoking showed significant relationships with intention to smoke in the future among non-smokers. Conversely, perceived lower prevalence of smoking among peers, weak contributory social influence, and greater awareness of the ill effects of smoking are factors associated with the intention to cease smoking sometime in the future. The study found that prevalence of intention to initiate smoking is low among non-smokers while the majority of current smokers intended to cease smoking in the future. Existing anti-smoking programmes that integrate the factors that have been identified in the current study should be put in motion to reduce the prevalence of intention to initiate smoking and increase the intention to cease smoking among adolescents.

    Heavy metals which are Pb, Co, Ni, Zn and Cd content in four Nephentes sp. plant component (roots, stem, leaf and pots) and in soil substrates from former iron and tin mining land at Pelepah Kanan, Kota Tinggi, Johor were determined. The composition of heavy metals in soil were extracted using a mixture of concentrated nitric acid and perchloric acid. Meanwhile, heavy metals in plants samples were extracted using wet digestion method. Heavy metals content in solution extract of soil and plant were determined by Flame Atomic Absorption Spectrophotometer (FAAS - model Perkin Elmer 3300). BAC (Biological Absorption Coefficient) which is a ratio of heavy metal content in plant to that of heavy metal in soil was obtained by calculation. The result of analyses showed that the former mining area has low organic matter contents and low values of soil electrical conductivity, whereas the soil pH showed an acidic value. Concentration of heavy metal in soil substrates in decreasing sequence start with Zn at 698.5 mg/ kg followed by Co (182.9 mg/ kg), Pb (58.2 mg/ kg), Ni (12.2 mg/ kg) and Cd (2.09 mg/ kg). Heavy metal concentration in plant in decreasing sequence was Ni>Co>Cd>Pb>Zn. Concentration in different part of the plant did not show any significant difference for all of the metals. Nepenthes sp. was found to accumulate high concentration of Ni as indicated by its high BAC value. This plant may be useful as bio-indicator for high concentration of Ni in soil. (author)

    Full Text Available Have performed experiments to compare the surface tension of water by the surface tension of alcohol use food dye. The research method is to perform a simple test. With a drop of food dye into water will make the water molecules become larger and when alcohol was dropped into the solution there will be a tug between water and alcohol with water or with alcohol-called cohesion. Tug between different molecules such as water to alcohol is called adhesion. Cohesion of water molecules is greater than the cohesion of the alcohol molecules. Cohesion of water is also greater than the adhesion between the two fluids. Competition between cohesion and adhesion molecules of water and alcohol lead to mutual attraction between water and alcohol resulting in vibrations when the fluid is met. The results obtained when this trial is water that has spilled food dye will move away from the alcohol and water colored parts that come into contact with alcohol will vibrate.

Berdasarkan hasil penilaian oleh Balai Konservasi Sumber Daya Alam Jawa Tengah (2001, hanya ditemukan kurang dari 50 jenis tumbuhan per hektar, sehingga dikategorikan sebagai kawasan miskin jenis tumbuhan dan perlu dilakukan upaya untuk mengatasi kerusakan lingkungan di dataran tinggi Dieng melalui konservasi lingkungan. Agar konservasi lingkungan berhasil, perlu adanya database kondisi lingkungan sehingga diperoleh cara konservasi yang tepat. Penelitian ini bertujuan untuk mengetahui tingkat kerusakan di dataran tinggi Dieng sebagai database guna upaya konservasi. Penelitian ini menggunakan metode eksplorasi secara langsung di lokasi penelitian melalui pengamatan, pengukuran, pemetaan, dan wawancara dengan petani dan aparat terkait. variabel yang akan diukur adalah tingkat kerusakan fisik lahan, kerusakan biologis lingkungan, dan aspek demografi, ekonomi, sosial dan budaya masyarakat. Hasil penelitian menunjukkan bahwa secara fisik, tingkat kerusakan lahan pertanian semakin parah, sehingga menurunkan produksi kentang di daerah ini. Secara biologis, tingkat keanekaragaman jenis tanaman liar berkisar antara 0,81 – 0,98, dan termasuk kategori rendah. Dari aspek perilaku penduduk dalam upaya konservasi, belum menunjukkan hasil, karena areal tanaman kentang menjadi semakin luas akibat penebangan hutan konservasi. Tingkat kerusakan lingkungan di daataran tinggi Dieng semakin parah, sehingga dapat menurunkan produksi kentang. Saran yang dapat disampaikan adalah perlunya dilakukan upaya pengelolaan dan konservasi kawasan Dataran Tinggi Dieng. Oleh karena kondisi geografisnya, pola usaha pertanian yang dilakukan di Dieng harus diikuti dengan kajian konservasi lahan, perlunya dicari tanaman pengganti kentang yang dapat mencegah terjadinya erosi.   ABSTRACT  Wild deforestation to expand potato cultivation

    Abstrak. Menggagas Pendidikan Berwawasan Kewirausahaan Di Perguruan Tinggi Islam: Studi Kasus Fakultas Syari`Ah Dan Ekonomi Islam Iain “Smh” Banten 2014-2015. Penelitian ini berangkat dari keprihatinan terhadap tingginya tingkat pengangguran di kalangan para sarjana lulusan perguruan tinggi (Islam dan masih rendahnya proporsi pengusaha di Indonesia. Padahal tingginya proporsi pengusaha dapat menjadi salah satu indikator kemakmuran sebuah negara. Oleh karena itu timbul pertanyaan sejauh mana nilai-nilai Islam mendorong budaya wirausaha di kalangan umatnya? Dan bagaimana budaya wirausaha ditumbuh-kembangkan di lembaga pendidikan tinggi Islam? Penelitian ini bersifat deskriptif eskploratif dengan studi kasus pendidikan kewirausahaan di Fakultas Syari`ah dan Ekonomi Islam (FSEI IAIN “SMH” Banten. Hasil penelitian menunjukkan bahwa kurikulum prodi-prodi yang ada di FSEI belum sepenuhnya berwawasan kewirausahaan. Mahasiswa umumnya banyak dibekali dengan kompetensi dan ketrampilan yang mempersiapkan mereka sebagai sarjana ekonomi syari`ah yang akan mengisi profesi-profesi yang membutuhkan kompetensi di bidang ini seperti manajer, dosen, peneliti, dewan pengawas syariah, dan sebagainya, ketimbang profesi wirausahawan yang berkompetensi untuk merintis usaha dari bawah. Untuk membangun prodi kewirausahaan Islam/bisnis syari`ah di FSEI IAIN SMHB dibutuhkan political will yang kuat dari tidak hanya pihak kampus tetapi juga lembaga otoritas seperti Diktis Kemenag untuk memfasilitasi berdirinya prodi ini baik dari segi perizinan maupun pendanaan. Studi kelayakan awal yang lebih komprehensif perlu dilakukan untuk memetakan kebutuhan sarana dan prasarana seperti kebutuhan formasi dosen yang qualified di bidangnya, struktur kurikulum yang dapat membekali mahasiswa dengan berbagai karakter dan ketrampilan sebagai (calon pengusaha handal, dan sistem perekrutan untuk menjaring calon mahasiswa unggul.

    Full Text Available Abstrak— Photovoltaic (PV merupakan sumber energi terbarukan yang paling banyak dijumpai di alam serta merupakn energi alternatif yang sangat pesat perkembangannya. Untuk mengahasilkan daya, sebuah PV dipengaruhi sebuah nilai intensitas cahaya matahari yang mengenainya. Sebuah sistem PV membutuhkan sebuah kontrol yang bertujuan untuk meningkatkan efisien daya PV tersebut. Kontrol ini adalah Maximum Power Point Tracking (MPPT yang dapat mengoptimalkan daya yang dihasilkan oleh PV.  Sebuah PV hanya menghasilkan nilai tegangan yang rendah, untuk itu perlu menggunakan koverter DC-DC step up untuk menaikan rasio tegangan DC tadi. Untuk mengoptimalkan sistem ini, diperlukan sebuah konverter yang efisien dan dapat menghasilkan rasio konversi tegangan yang tinggi. Pada penelitian menggunakan firefly algoritm (FFA dan modified perturb and observe (P&O sebagai MPPT untuk mendapatkan nilai daya optimal pada keluaran PV.  Konverter DC-DC yang digunakan adalah hybrid cuk converter boost mode yang memiliki rasio tegangan yang tinggi. Dari DC-link kemudian masuk ke inverter (VSI yang diinterkoneksi dengan grid menggunakan current control. Hasil analisis simulasi menunjukan bahwa FFA dan P&O mampu menghasilkan daya PV yang optimum dengan riak yang kecil dan konverter hybrid cuk converter boost mode dapat menghasilkan rasio tegangan yang lebih besar dibandingkan konverter cuk biasa.   Kata Kunci — PV, MPPT FFA, MPPT P&O, Hybrid Cuk Converter, DC-Link, Inverter Grid Connected

    Full Text Available Pada pipa yang dipendam didalam tanah sering terjadi kegagalan deformasi. Kegagalan deformasi global yang menyebabkan pipa menekuk vertikal ke atas yang disebut sebagai upheaval buckling. Lengkungan awal pada pipa penyalur yang terpasang bisa terjadi akibat kombinasi dari kenaikan temperatur saat operasional dan gaya friksi tanah akan menghasilkan gaya tekan aksial efektif pada pipa. Salah satu cara yang akan dibahas pada penelitian ini jika terjadi upheaval buckling adalah pemasangan loop ekspansi pada daerah yang mengalami upheaval buckling. Loop ekspansi akan divariasikan dengan 2 tipe yaitu tipe loop horizontal dan tipe loop vertical. Pada penelitian ini terlebih dahulu pipa dimodelkan dengan panjang pipa tertentu kemudian ujung-ujungnya diberi tumpuan sehingga didapatkan besar tegangan longitudinal sebesar 41366,563 Psi. Tegangan tersebut melebihi tegangan ijin sehingga pipa mengalami ekspansi termal atau elongasi yang membentuk lengkungan keatas dengan tinggi 0.259 meter. Maka dilakukan pemodelan loop ekspansi untuk meredam elongasi tersebut dengan panjang loop 5.3 meter. Kedua loop tersebut mampu meredam tegangan aksial menjadi 3662 Psi untuk tipe loop horizontal dan 3670 Psi untuk tipe loop vertikal. Dari kedua tipe loop tersebut kemudian juga dilakukan perbandingan besar tegangan yang terjadi pada bagian elbow. Maka didapatkan bahwa tipe loop horizontal mengalami tegangan relatif lebih kecil dari pada tipe loop vertikal sehingga sebagai bahan rekomendasi maka pemasangan loop horizontal lebih diutamakan.

    Full Text Available Vacuum tube amplifiers have been known as softly-cliping audio amplifiers, as opposed to solid-state based amplifiers which exhibit hard-cliping properties. However, vacuum tubes are operated in high voltage level. Meanwhile, in order to work in low voltage level, a vacuum tube amplifier must employ step down transformers that leads to complexity. This study aims to make use of vacuum tubes in a pre-amplifier working on 12 VDC level. First, several measurements were done to obtain graphics of characteristic of triode 12AT7 in low voltage level. Common-cathode topology was cascaded with a common-anode topology to realize such amplifier. The results show that the preamplifier has an input impedance of 1.11 MΩ, output impedance of 3.5 kΩ for the right channel and 3.2 kΩ for the left channel. Maximum Total Harmonic Distortion of 1.7% occurs on frequency of 4 kHz. Voltage gains of 20.08 dB and 20 dB were obtained for the right and left channels, respectively. This pre-amplifier also shows sensitivity of 212 mVrms, maximum output level of 2 Vrms, and relatively flat frequency response within 60 Hz–20 kHz with ripple of ± 0.5dB. This pre-amplifier can be alternatively used in two modes, namely linear mode and distorted mode.

    Full Text Available Indonesia is a tropical area with a high intensity of repeating lightning strikes. The voltage is produced by lightning by increasing the presence of sensitive loads. Therefore, lightning can easily worsen the quality of consumer power, even if the generated voltage is relatively low. Lightning strikes can cause excessive voltage along the power lines. Its propagation can cause a voltage surge on low voltage systems, which can damage the equipment. Maintenance and protection against lightning strikes are necessary for the prevention of such damage. Arrester is a device that is intensively used nowadays by the general public to protect equipments from lightning strikes. It is used to protect the system from the danger of lightning by flowing current into the ground and leaving a certain resistance value, so that the system does not experience a surge voltage.This research was conducted through laboratory-scale testings using several major equipments, such as a high voltage generator, an impulse voltage generator, and an oscilloscope. Modifications of the tests were done using one to four 220 volt low voltage Merlin Gerin LTD arresters arranged in series, with a maximum current of 6.5 kA . Calculations using equations for low voltage circuit in series were done for more than four arresters. From the test results, it was found that the characteristics of the arrester residual voltage will rise when connected in series. Low voltage arresters can be used for higher voltage requirements by counting the number of arresters needed. The equation for the number of arresters in series required to cut the overvoltage surge is y = 0.694x – 0.106. Therefore, if more than 4 arresters will be needed, the residue voltage can be estimated through this formula.

    Full Text Available Baterai Lithium Polymer merupakan baterai yang banyak digunakan pada saat ini, baterai Lithium Polymer dapat mensuplai dengan arus yang tinggi hingga mencapai dua puluh kali kapasitasnya. Selain itu desain baterai Lithium Polymer lebih kecil dibangkan dengan baterai Lead Acid maupun Ni-CD dengan kapasitas yang sama. Akan tetapi baterai Lithium Polymer mempunyai beberapa kelemahan. Salah satunya yaitu dapat rusak jika overcharging dan over discharging. Pada alat – alat tertentu sel baterai Lithium Polymer disusun secara seri untuk menaikkan tegangannya. Penyusunan sel baterai secara seri membuat perbedaan tegangan saat charging maupun discharging pada masing – sel baterai. Perbedaan tegangan tersebut menyebabkan sel baterai tidak terisi penuh secara bersamaan sehingga menyebabkan overcharging pada sebagian sel baterai. Hal ini menyebabkan rusaknya sel baterai dan bisa menyebabkan baterai meledak. Pada penelitian ini akan didesain dan diimplementasikan Penyeimbang Baterai Lithium Polymer Berbasis Dual Inductor. Penyeimbang ini merupakan pengembangan dari Buck-boost converter dengan penambahan induktor dan flying capacitor . Hasil implementasi menunjukkan bahwa penyeimbang baterai dapat menyeimbangkan tegangan tiga sel baterai dengan perbedaan tegangan yang tinggi.

The embedded bad image and false myths about entrepreneurs has made its spread very low in Indonesia. Universities in Indonesia are looking for a more effective form of teaching entrepreneurship so as to produce graduates who are productive rather than educated, but unemployed graduates. Entrepreneurship is very unique because it contains multiple disciplines. There are various forms of teaching entrepreneurship used by different countries in the world from various literatures. Universities and entrepreneur lecturers should be able to take an example on (adapt and adopt how to teach according to the college culture and taught students, without having to look at what disciplines the student is enrolled in, also by integrating the values of entrepreneurship in the curriculum and extracurricular activities as supporting activities. Thus, entrepreneurial atmosphere can be created within the campus so that students, during their stay in college, do not seem to have lived and becoming used to a dynamic entrepreneurial environment, inspiring, and full of innovation.

    Full Text Available Voltage stability evaluation is needed to get the information of electrical power distribution system performance. Power flow calculation is used to determine the important parameters of power system in a steady state. An electric power system must have voltage value that does not exceed the limits of tolerance and the power loss as well as small. The improvement of voltage profile can be done by using voltage-control equipments, such as capacitor banks and transformer tap. Through simulation using the PowerWorld simulator, the value and location of capacitor banks and transformers tap will obtained in order to improve system performace. Sumbar electrical system was used in this study. From the simulation results, for the initial condition of the system, there are several buses that have voltage drop with total system losses 14.4 MW. After capacitor added, the system voltage has increased significantly so that no one passed the value of tolerance and the losses in the system down to 14.1 MW. As for setting the ratio of tap transformer, voltage system did not change so much, except on the secondary side of the transformer bus arranged with system losses almost the same that equal to 14.4 MW. For the case of the addition of the capacitor and transformer tap settings in the same time, the voltage drop no longer exceeds 5% and the total system losses decreased to 13.9 MW.

    Full Text Available This article proposed to revitalize a philosophical paradigm in the academic tradition of Islamic Higher Education (IHE as a scientific endeavor to pave the way for the revival of Islamic civilization. IHE was selected because its academic tradition institutionally is more likely to hold it than other Islamic educational institutions such as pesantren that tends to play a “prophetic” role as the guardian of religious orthodoxy. The revitalization held to establish three agendas, namely (1 terminating the dichotomous epistem-ology and then moving on an integrative epistemology, (2 applying multidisciplinary approaches in scientific activities, and (3 strengthening the spirit of criticism and freedom of thought as fundamental principles of the scientific dynamics. Due to the academic traditions concerning intellectual praxis, the agendas have to paint the scientific activities in IHE, from design of sciences to norms of intellectual promiscuity. Establishing three agendas into the academic tradition paradigmatically will enable IHE to creat significant contributions to the revival of Islamic civilization in the future.

    Full Text Available Dewasa ini penggunaan material komposit sudah sangat berkembang. Komposisi dari komposit juga sudah sangat beragam, namun penelitian tentang komposit Polyester – Hollow Glass Microspheres (HGM dengan variasi temperatur curing dan post-curing untuk karakteristik tekan masih sangat terbatas. Keunggulan yang dimiliki HGM antara lain memberikan bobot yang ringan, konduktivitas termal rendah, dan ketahanan terhadap tegangan kompresi yang tinggi. Komposit Polyester-HGM dapat diaplikasikan antara lain pada bemper atau body kendaraan sehingga dapat mereduksi berat total kendaraan dan meningkatkan efisiensi kendaraan. Penelitian dilakukan dengan mencampurkan polyester resin dan HGM. Spesimen uji tekan dibuat dengan dimensi sesuai ASTM D-695 dengan variasi fraksi volume HGM 10% hingga 17%. Spesimen menerima tiga perlakuan yang berbeda yaitu: (1 Spesimen I di-curing pada temperatur kamar (± 27°C ditahan selama 24 jam; (2 Spesimen II di-curing pada temperatur kamar (±27°C ditahan selama 24 jam lalu post-curing pada temperatur 90°C selama 5 jam; dan (3 Spesimen III di-curing pada temperatur 90°C ditahan selama 24 jam. Untuk mempelajari perbedaan sifat mekanik yang terjadi, dilakukan pengujian tekan. Pada penelitian ini dapat diketahui bahwa kekuatan tekan dan ketangguhan maksimum terjadi pada komposit dengan fraksi volume HGM 17%. Semakin tinggi temperatur curing akan meningkatkan nilai kekuatan tekan dan ketangguhan dari komposit polyester-HGM. Hal ini terjadi karena komposit yang di-curing pada temperatur tinggi memiliki ikatan crosslink lebih banyak sehingga ikatan polyester dan HGM lebih kuat dan nilai kekuatan tekan pada komposit akan meningkat.

    Full Text Available The quality of the overhead distribution voltage with a length of ± 190,57 kms, in the North Gorontalo district has not met the National Standard for the distribution voltage yet. This causes a voltage drop along the distribution line at 21% during the peak load and the power loss at 219 kW. This paper aims to find the best solution for improving the voltage quality of the distribution line to meet the standard operation voltage for the medium distribution line. The Newton-Raphson method is used to analyze the power flowing along the distribution line and the voltage at their buses. There are three scenarios purposed in this study. The first scenario is to uprate the conductor size (in LK. 01 feeder, the second scenario is to reconfigure the distribution network after the Anggrek Substation was connected to the system and the third scenario is to combine the first and the second scenarios, i.e. uprating conductors and reconfiguring the network. From the three scenarios, the results show that the first scenario has a voltage drop of 19,8%,  the second scenario causes a voltage drop of 8,8% and the third scenario produces the voltage drop of  4,8%. Based on this results, it can be concluded that the third scenario can improve the line voltage much better than the other two scenarios with the power loss of up to 52,4 kW. The Entry of Anggrek Substation must accompany by conductor uprating in line distribution to reach limit voltage standard operation.

    Full Text Available This research focused on the experimental study on the residual stress magnitude and distribution resulted from the welding process in and around the k area of the link element. The measurement was done with the Neutron Diffraction Method using the Neutron Diffractometer DN1-M PSTBM BATAN. A number of 15 points with 45 measurement directions were conducted on the k area in normal, transversal and longitudinal directions. The result of the experiment showed 185 Mpa and 160 Mpa residual stress magnitude in longitudinal and transversal directions in the same directions with the weld toe welding between the web and flange with the extent of the stress area 8 times of the flange thickness. The perpendicular welding of the weld toe resulted in 162 Mpa and 145 Mpa residual stresses in longitudinal and transversal directions with 4 times stress area extent from the flange thickness. The residual stress magnitude and the width of stress area indicated the k area as a vulnerable area to the initial crack occurrence, which may decrease the link performance. Making a welding gap 4 to 5 times of the flange thickness between the stiffeners and the flange may increase the link performance because it may minimize the residual stress magnitude and distribution.

    Full Text Available The kind of Islamic sciences being taught in many higher education institutes in Indonesia is that which tends to make students isolated from their world. These Islamic sciences in themselves are kind of separation from the religious and worldly, Islamic and secular. This dichotomous character had inflicted upon the students mentality, who in turn become equally dichotomous in their attitude, and way of thinking. This paper tries to explore this, and attempts to seek the best way in which the dichotomous curriculum can be replaced with the integrative one. It argues that, like the nature of Islam, religious sciences cannot be separated from the non-religious ones. The one must work hand in hand with the other so that. The paper addresses specifically the dilemmas intrinsic within the text book used by many higher religious institutes in the country called “Reorientasi Pendidikan Islam: Menuju Pengembangan Kepribadian Insan Kamil”. The book—we argue—directs the students to adopt a single identity, disregarding therefore the multi and diverse racial, religious and even cultural background of the students. The paper is simply about a warning of the danger of the implication that the book can come up.

This study tried to developed snack foods for school children with portion size of 300 Kcal and 5-7 g protein, and evaluated for their glycaemic index and organoleptic quality. Basic ingredients for food formulation were carbohydrate sources: rice, glutinous rice, cassava, or sago; protein sources: soybean, chick peas, peanut, mungbean or tempe; besides other ingredients such as sugar, coconut oil, grated coconut or coconut milk those were added to increase palatability and energy content. Carbohydrate and protein sources were processed under optimal treatment, which were: soaking at pH 5.8-9.6 and followed by overnight drying and roasting at 75-125o C for 30 minutes. Those treatments were to reduce portion size and to increase the glycaemic index. This study involved adult women and school children to evaluate the portion size and the organoleptic quality. Snack foods in form of smooth or coarse sweet jellied dough had good acceptability. The glycaemic index of 15 snack foods are varied between: 64-99. These indexes are considered as moderate to high. Further study is needed to evaluate the energy effectiveness of the snack foods on maintaining and enhancing the work performances of school children.Keywords: formulated food, nutrients, organoleptic evaluation, glycaemic index.

    Full Text Available Indonesian children’s growth are monitored monthly and can be seen by the KMS graphic and posyandu cadre’s book. The data from posyandu activity will be evaluated by the government health department. In practice, there are many obstacles to make posyandu works ideally. First, the cadres of posyandu have a difficulty to use the conventional anthropometric equipment, so the measurement data may not be valid and precise. Second, noting the KMS graphic needs an accuracy. Third, the measurement result in posyandu is not rapidly integrated to the central health data. A technology innovation of automatization anthropometry measurement called OTOTIM designed for infants that supported by an integrated information system is needed to solve those problems. OTOTIM designed to make anthropometric measurement for infants more fast, valid, and accurate. The measurement result will be stored in the database and transferred to an image that describe the nutrition status in the KMS. Microcontroller will process the data from load sensor that measure baby’s weight and ping sensor that measure baby’s height. Then those raw data will be sent to main component of OTOTIM, which is the software itself to gain informative result of measurement, that consist of right suggestion on what kind of treatment used to take care various nutrition condition of infant and comparison against the previous measurement. OTOTIM will also generate statistics which group the infant by nutritional condition for each month. Those statistics will also include information on how percentage of male and female babies which have certain nutritional condition. However those statistic will provide information which is relevant only for specific district as OTOTIM used in regional manner. In order to create statistic which is relevant to consumed by public, those measurement data must be processed in central server which can calculate whole data and grouped them by nutritional condition. OTOTIM introduces the central server that bring synchronization service between OTOTIM software which is installed locally on client PC and the server itself. OTOTIM software have to establish a connection to server to publish subdistrict-specific statistic, however this connection is not mandatory to run primary function. So if client have trouble to connect, this will not interrupt the primary function as OTOTIM supposed to run in less-signal environment.

    Full Text Available Working Assessment is very essential aspect for a college to keep its excellent quality to face tight competition in either national or international level. The working assessment can be implemented to compare the result with organization strategy, and can also help to plan the upcoming strategy to achieve the final target of organization. The combination of Balanced Scorecard and OMAX is aimed at building the information system of working assessment in a college. Balanced Scorecard in the college is used to determine the strategic purposes, KPI and target, optimistic and pessimistic value. The scoring of each KPI uses AHP method; the scoring of KPI influences on general working score. The scoring of working assessment uses Objective Matrix (OMAX method to know the total result indicator stated by the college, and can find out the total result indicator of each working criterion. The combination of BSC and OMAX can avoid the use of overwhelming data because this model focused on four perspectives, with the important key indicator of a college. Besides, the four perspectives can avoid the orientation of short-term target, because OMAX developed the more obvious frame of time that also focused on the long-term target. This combination was a good integration that can afford to modify hybrid model in determining the score card of a college. BSC changed into the form of OMAX that presented a target in the long period. This combination is also a good integration that can afford to modify a hybrid model in determining the scorecard of the college.

    Full Text Available Background. Iodized salt is universal effort to eliminate iodine deficiency disorders (IDD. Iodine consentration in iodized salt needs to be evaluated due to many cases of hypothyroid and hyperthyroidism. Objective. The purpose of this study was to describe whether iodized salt consumed by peoples contributes to hypothyroidism and hyperthyroidism cases. Method. This was a descriptive study in area with the highest cases of hypothyroidism and hyperthyroidism based on data from Klinik Litbang GAKI Magelang 2005-2012. Samples were taken using purposive sampling with a sample size of 90 households per area. Area with the highest case of hyperthyroidism is Mertoyudan Sub District while area with the highest case of hypothyroidism is Salaman Sub Districts, both in Magelang District. Iodine content in salt was by taking sample of salt from households which used for daily consumption. Statistic analysed used were independent sample t test and Chi Square. Result. The results showed that salt consumed in both areas already contains iodine. Salt iodine content level in area with the highest hyperthyroidism (55.1±23.84 ppm was higher than in the area with the highest hypothyroidism (49.79±39.28 ppm. According to the category of iodine content in salt, iodine content below standards (<30 ppm is higher in area with the highest hypohyroidism (25.6 percent. Iodine content above standars (>80 ppm is higher in area with the highest hyperthyroidism (13.2 percent. However iodine content in both areas showed no significant difference (p=0.27. Conclusion. Iodized salt consumption does not contribute to the high case of hypothyroidism or hyperthyroidism. Salt consumed in area with the highest cases of hypothyroidism and hyperthyroidism already contains iodine as standard. It is possible that there are other factors that cause high incidence of hypothyroidism and hyperthyroidism in those areas that needs further research.Keywords: hyperthyroidism, hypothyroidism, iodine, salt

    Full Text Available The development of the quality of religious universities in general is still left behind. One of the causes, construction of the foundation of quality in religious colleges is still partial. This article attempts to identify the quality of general religious college education in Indonesia through critical analysis and offers alternative solutions to improve it. One of the right models to improve the quality of education is the global quality assurance model. This model is an integration of PD Dikti quality standards, quality standards of National Accreditation Board, internal quality audit, Webometric, and religious institutions distingsi standards. As for improving the quality of education and learning of lecturers and students are able to produce learning products in the form of books and scientific articles published in national and international scientific journals as well as increasing the competence of graduates. Therefore the aspects of ontology, epistemology and axiology in the integration of science in the curriculum of education need to be constructed with critical interrelation model. This model is relatively effective enough to anticipate the occurrence of pseudo interconnects, preventing hybridity and new hegemonic scholarship in the pattern of interconnectivity and protect the characteristics of every science.

    Full Text Available Design Program of Microcredit Activity (Revolving FundFor Students in Higher Education. Systems design of microcredit is generally conducted by financial institutions of which credit is mostly provided for private sectors, both large and small medium Enterprises (SMEs. However, credit for new entrepreneurs, especially for college students, who want to start a business has never been provided formally due to numerous factors and among others is because of the absence of collateral. Meanwhile, in order to stimulate the eagerness of running a business, credit is inevitably essential. Hence, this study is proposing a comprehensive systems design to overcome any potential problems between new entreprenurs in getting credit from financial intitutions. This systems design handles a series of processes in granting credit which starts from screening and selecting business proposals. When the proposals are accepted and the credit is granted, then they will get processes of mentoring, training, exhibition and finally process of monitoring through financial reports. Also there will be internet facility of integrated microcredit information system to ease communication between the new entrepreneurs, mentors and financial institutions. This systems design can enhance success for the new entrepreneurs and diminish any potential risks of unable to repay the credit. So when the business starts to grow, they can apply for bigger credit.DOI: 10.15408/ess.v5i1.2329

Thereby, the dental professional is better to make a specific prevention and treatment recommendations to reduce a child risk and improve overall oral health. The goal of caries-risk assessment and preventive treatment is to eliminate caries or at least to reduce the high-caries occurrence down to the level of the remaining part of the age group. Preventive treatment is divided into three parts: primary, secondary, and tertiary prevention. This paper describes the primary prevention in children with high caries risk by behavior modification and tooth protection. Behavior modification is about dental health education, oral hygiene, diet and sugar consumption, sugar-free chewing gum and sugar-free medicines. Tooth protection is about sealant, usage of flouride and chlorhexidine.

Most of the study related to nutritional status of school children indicated the hidden hunger syndrome, where the student did not have breakfast or something to eat during school time which caused low performance in school. Some interventions had been done to improve their school performances, such as giving iron tablets or traditional school lunch three times a week. Neither of those practices gave good results. Process foods especially carbohydrate part can increase its absorbability to make blood glucose in the normal level during study time. The food formulas using processed carbohydrates had been developed to make high glycaemic index snack for school children. Objectives: The study objectives were to evaluate the effect of high glycaemic index foods on school performance of the elementary school children.Methods: Samples came from two diferrent elementary schools were purposively selected into 2 groups. One school as control group and the other one as treatment group. Each school consisted of 3rd + 4th grades and 5th +6th grades, with 56 children per grades. Control groups were given snack foods were bought from vendor around the school, while the treatment groups were given the high glycaemic snack foods prepared in laboratory. Foods were given at break time, every day in the first month of intervention; 3 times a week during the second month and none during the third month. Anthropometric measurement, blood glucose, Hb, Ht and school performances were evaluated every month during intervention. The data were analyzed to compare the changes in all variables measured on all groups using Studentized-t test. Results: Body weight of both groups increased after one month intervention, especially for younger students, and those were significant increase after 3 months intervention. Hemoglobin level did not change significantly, while blood glucose increased in the first and second month of intervention in the treatment group.; it was the opposite of the control group. Daily intervention significantly increased the school performance of the younger students in the treatment group. After 3 months study, the school performance in all groups were higher than that before intervention. Conclusions: High glycaemic snacks foods had smaller portion size than common snack foods sold in the school area, had higher nutrient content, and were accepted well. School performance of treatment group were better than that of control group, especially if the snack food given daily. The results can be implemented on the national school lunch program while promoting the local food based snacks.

    Full Text Available The major routes for HIV transmission in Indonesia are injecting drug use and heterosexual activity. More than halve of the proportion of estimation 2006 of people living with HIV/AIDS were IDUs. Around 70 percent of all reported AIDS cases of IDUs in Indonesia occur among those in the age group of15-29 years. It indicates that young people are not only at high risk of contracting HIV infection but already constitute a significant percentage of people living with HIV/AIDS. This article is examines adolescent risk behavior on HIV transmission in Indonesia. The data were obtained from Behavioral Surveillance Survey 2004-2005 of 6352 female sex workers and 2969 their clients in 14 provinces, 1052 transsexual in four provinces, and 1795 IDUs in five cities as well as 1001 male student and 1159 female student in two cities. This survey reveals that adolescent's high risk behavior on HIV transmission is not only through injecting drug use but also through heterosexual. Of great concern is that 40 percent of the female sex workers and more than halve of IDUs aged 15-24 years. Findings also show that risk behavior is associated with age of respondent. Younger ages of IDUs were more like to have more than one sex partners and sharing needle; and again 27 percent of younger ages 15-19 year have started to be involved in high risk behavior as IDUs age below 15 compared to age 20-24 and 25+ nine and one percent respectively. Furthermore, the younger ages of sex workers and their clients were less likely to use condoms; and around 25-60 percent of them have begun to work as commercial sex workers age below 20.The findings of this survey raise concern about risk behavior of HIV transmission among adolescent. The need to focus more policy and program attention on adolescent sexuality and drug use behavior is compelling. Keywords : adolescence, risk behavior, HIV transmission

    Full Text Available Pesantren is an educational institution after the recitation of the Qur'an in the entire territory of Indonesia. Pesantren distinctive shape and varied makes its presence continues to grow, but a significant development came after an intercourse with the school system or also known as the madrasa system. The growth of Islamic madrasah education is a response to the school system that has been the policy of the Dutch government within the framework of ethical politics. Growth and development of madrasas in the early 20th century is part of the Islamic reform movement in Indonesia, which has a fairly intensive contacts with the reform movement in the Middle East. One form of the dynamics and development of the earliest schools is the mixing between the boarding school system with madrasa system. Both institutions, initially stood alone. Model of teaching at a boarding school in the classical delivered in the mosque or surau with sorogan method, while teaching models delivered modern madrassa in the class room with a varied methods. Marriages between boarding school with this madrasah, has brought a lot of progress in the world of boarding schools. Model Integration madrasah/boarding school is divided into four, namely: Full Integration, Integration Selective, Instrumental Integration, and Integration Minimal. The meeting point of the integration of schools with madrassas, Islamic schools and Islamic Universities with Pesantren or vice versa is equally Aiming internalization of Islamic values, independence, sincerity and simplicity and personality formation holistic: an individual can find the identity, purpose and meaning in life through relation to society, spiritual values that can address the challenges and needs of the times.

    Full Text Available Accurate and adequate treatment of STIs is a critical component of STI-control activities to reduce transmission and sequelaes. On the other hand, chronic shortage in skilled staff and laboratory equipment in many countries necessitate the use of clinical skills more in order to diagnose and differentiate STIs. For these places, the WHO has recommended and produced a protocol of it syndromic approach management of STIs in place of treatment by -etiology. Since 1997 the Indonesia Ministry of Health has been conducting national training on this method. However, the syndromic approach for vaginal discharge is known to be problematic since differentiation among cervicitis, vaginitis, and even normal condition is difficult. The main objective of this study is to determine the sensitivity, specificity and positive predictive value of the syndromic approach management of women with signs and/or symptoms of abnormal vaginal discharge. The sample population were women with high risk sexual behaviors in East Java and North Sulawesi provinces. The laboratory tests using DNA hybridization probe technique (the PACE 2 test, Gen-Probe, San Diego, Calif. for Neisseria gonorrhoeae and Chlamydia trachomatis were used as gold standard. In addition, we also compared the clinical approach widely used by clinicians (mainly at hospitals with laboratory results. A total of 439 participants was recruited purposively (230 from E. Java and 209 from N.Sulawesi. In E.Java, the sensitivity, specificity, and predictive value of the syndromic management for vaginal discharge are 31%, 83%, and 59%, respectively, and in N.Sulawesi 49%, 56%, and 40%,respectively. The clinical approach did not show better results. In E.Java the sensitivity, specificity, and positive predictive value are 13%, 89%, and 50%, res­pectively, while in N.Sulawesi they are 42%, 61%, and 39%, respectively. As a conclusion, the current form of syndromic management has little use for STI screening among high risk women. Further studies by adding more criteria to the syndromes are needed to improve this method.

    Full Text Available Effects of additing 1 percent (w/o palladium (Pd on the thermal behavior of a lathe cut type high copper amalgam (13 w/o copper were studied. The identical alloys, with and without 1% Pd were fabricated. X-ray diffraction studies of the amalgams revealed the elimination of the γ2-phase by Pd addition DSC thermogram of non-Pd containing amalgam indicated the existence of two γ1-phaseone with the transition temperature (endothermic peak at 88◦C and the other at 109◦C. The thermogram data of the Pd containing amalgam showed an endothermic peak at 110.7◦C. The transition temperature of the n phase of the palladium containing amalgam is 4.9◦C lower than the transition temperature of the n phase of the non Pd containing amalgam. This result indicates that the n phase of the Pd containing amalgam includes more of Tin (Sn than the non-Pd containing amalgam. The thermogravimetri diagram showed that the phase decomposition occurred at about 390◦C for the non-Pd containing amalgam and at about 410◦C for the Pd containing amalgam. It is concluded that the addition of 1% Pd into a lathe cut type of high copper amalgam (13% could eliminate the formation of γ2 phase as well as an unstable γ1 phase, promoting strong mercury bonding to Silver.

    Full Text Available Energi Angin merupakan salah satu energi alternatif yang sangat menjanjikan jika dapat dimanfaatkan dengan baik. Pemanfaatan energi angin untuk diubah menjadi energi listrik dapat menggunakan turbin angin dan generator. Turbin angin tipe Savonius merupakan rotor angin dengan sumbu tegak (vertical yang dikembangkan oleh Singuard J. Savonius pada tahun 1920. Salah satu kelemahan yang dimiliki turbin Savonius yaitu efisiensi yang rendah. Torsi dan putaran yang dihasilkan oleh turbin Savonius disebabkan oleh adanya perbedaan gaya drag pada advancing blade dan returning blade. Salah satu cara untuk meningkatkan performa turbin Savonius  dapat dilakukan dengan pemberian plat pengganggu didepan returning blade. Untuk meningkatkan performa turbin Savonius dengan diameter D sebesar 60 mm dan tinggi h sebesar 80 mm, sebuah plat dengan tebal 3 mm dan lebar 84,9 mm digunakan sebagai pengganggu yang diletakkan didepan returning blade turbin. Pengganggu tersebut diletakkan dengan pada sudut 0o< ɑ < 90o. Penelitian ini dilakukan pada subsonic open circuit wind tunnel. Alat ini memiliki panjang 2980 mm, dengan test section 304 mm x 304 mm. Kecepatan free stream pada wind tunnel diatur sebesar 8,752 m/s, 10,94 m/s, 13,128 m/s, sesuai dengan Reynolds number Re = 6.0 x 104, 7.5 x 104, 9.0 x 104 (berdasarkan panjang karakteristik d = 2D-b, dimana b adalah lebar diameter overlap dari kedua sudu turbin, dan kecepatan free stream.

    Full Text Available Laser-Induced Breakdown Spectroscopy (LIBS is a technique that used for quantitative elemental analysis of various samples in different forms. In this technique, a laser light is focused on the surface of sample yielding a plasma just above the sample surface that used for analytical source. Nowadays, rapid powder analysis in tiny amount (mg has been carried out using plasma induced by high power laser of  Nd:YAG (Neodymium-doped Yttrium Aluminium Garnet at atmospheric pressure. However, powder analysis using high power laser is still difficult to be carried out  due to blow of powder when irradiated laser beam focused on a powder sample. In general, the powder must be transformed into pellet form prior to analysis. Pellet sample requires a lot of powder and it takes time for preparation. In this study, we developed a technique of powder sample with its size about  30 µm (± 5 mg that mixed with silicon grease (± 5 mg that act as a binder. The mixed sample then thinly painted on the metal plate as sub-target. The study showed that by employing sillicon grease technique, a semiquantitative analysis of several elements contain in coal, rock, and  water  can be conducted. Meanwhile heavy metal in soils is still not able to detect. This results showed that sillicon grease technique using  Nd:YAG laser can be applied for rapid semi-quantitative analysis of powder samples available only in tiny amounts.

This paper intends to conduct discourse criticism studies toward doctrin with thinking “jihad” to shift the thinking sacret ‘fiqh’ which is formalized. In promoting the eradication of corruption, Islam can play a role in various forms. Moral values taught at least provide answers about the spread of  corruption with interpretation radicalization toward Islamic moral values.

Dalam menggalakkan pemberantasan korupsi, Islam dapat berperan dalam beragam bentuk. Nilai-nilai moralitas yang diajarkan setidaknya memberikan jawaban semakin menyebarnya praktik korupsi dengan radikalisasi interpretasi terhadap nilai moralitas Islam.

    Full Text Available Students at higher education institutions are definitely adults who should be encouraged and given motivation to be the 'adult' learners. Each student has diverse characteristics that will make them ultimately bring different perspectives to the class (different types of backgrounds, learning styles, experiences, and aspirations. Therefore, educators are no longer possible to use conventional methods in cultivating the values to students to get them to be adult learners. The psychological condition of adults will encourage the teaching and learning process to be more directed to the Student-Centered Learning. This method is built on the principles of active learning constructive, some social activity, mental reflection, implementation of prior knowledge, and so forth. The learning process is a reflection cycle (about what happened, the idea of a thing (or something that needs to be tested, action (trial to do something, and outcomes (concrete experience. Problem-Based Learning method is an option that can be used to support the activities of Student-Centered Learning for the use of problems in the learning process can trigger the curiosity of students that will lead them to be able to solve their own problems by giving a definition of a certain problem and specify the collected information. In this way, students will try to associate the information they have and be able to specify the topics they will learn more.

    Full Text Available In our previous analysis of trusses, it was always assumed that the truss members are joined by idealhinges and that loads are applied only at joints. The centroidal axes all of members are stright,coincide with the lines connecting the joint center, and lie in a plane that also contains the lines ofaction of all the loads and reaction. Thus the members of truss are subjected to axial force only, andthese can be determined by static method. A stress analysis base on these assumtion leads to thedetermination of so – called “primary stresses”.In actual cases the joint are usually riveted or welded; and because of this fact the members undergo,not only axial forces, but also bending stresses from secondary moment, cuased by this condition arecalled “secondary stresses”. In discusing secondary stresses we shall consider only trussses in oneplane and assume that this plane represents the plane of symmetri for all members and that externalloads are acting in the same plane. Of these the most important are caused by the fact that the jointare rigid, and hence the members are not free to change their relative directions when the truss isdeformed. This problem can likewise be solved very eficiently by means of moment distibution.From the first analyze result, it was obtained the scondary tension ratio with the primary tension at thepull shaft about 19.20 %.

Pada jenis intersecting shaft gear, tipe roda gigi payung spiral (spiral bevel gear  merupakan perkembangan dari roda gigi payung bergigi lurus (straight bevel gear. Kelebihan dari spiral bevel gear antara  lain adalah kemampuan transmisi daya dan efisiensi yang lebih besar pada geometri yang sama serta tidak terlalu berisik. Akan tetapi spiral bevel gear juga mempunyai kelemahan jika dibandingkan dengan straight bevel gear. Selain proses manufaktur yang lebih rumit, profil lengkung gigi spiral ini membuat distribusi tegangan yang terjadi menjadi lebih rumit untuk dimodelkan dengan persamaan matematika. Salah satu pendekatan yang dapat dilakukan adalah dengan menggunakan metode elemen hingga. Penelitian diawali dengan membuat model dari straight bevel gear dan juga spiral bevel gear yang sudut spiralnya divariasikan 20, 35, dan 45 derajat. Model dibuat dengan dimensi yang sama baik diameter maupun jumlah gigi gear. Langkah selanjutnya yaitu perhitungan analitis pada straight bevel gear dimana hasilnya akan dibandingkan dengan hasil simulasi statis. Setelah eror yang terjadi dibawah 15% maka dilakukan simulasi dinamis pada semua model yang telah dibuat yaitu straight bevel dan juga spira bevel gear. Hasil yang didapatkan dari penelitian ini adalah secara keseluruhan spiral bevel gear lebih kuat daripada straight bevel gear pada dimensi dan beban yang sama jika dilihat dari lebih kecilnya tegangan bending dan tegangan kontak maksimum yang terjadi. Tegangan terbesar terjadi pada jenis straight bevel gear baik pada tegangan bending maupun tegangan kontak sedangkan spiral bevel gear dengan variasi sudut Seiring spiral 35 mempunyai nilai tegangan terkecil.

    Full Text Available Education of geography for SLTA students (secondary school is aimed at teaching students to behave as members of a modern Indonesian society with self-confidence and capable of solving a variety of daily-life problems both at pesent and in the .future. Some problems which arise in the Indonesian society are both of a social and physical nature. For that reason, attention should be paid to these problems in the reaching and learning materials for the SLTA, especially during the geography lessons. Moreover, geography based on the study of social and physical phenomena on a national and international level, should widen the scope of perception of the students. Concerning the criteria for lesson materials, on the one hand the geography subject should comply with the SLTA. curriculum and on the other hand, the physical and human aspects of the subject should reflect daily life realities. The materials should be taught as a whole package, not as separated fragments of physical and human aspects, to satisfy the geographical paradigm. Another aspect which should be given due consideration, is the continuation of the geography education from nursery school up to the university, with the teaching materials adjusted to the respective school levels. A well-designed balance of geography education in the school curricula and lesson materials is thought to intensify logical deductive thinking and stimulates character development of the students. It is therefore the right moment for geography teachers to reconsider the geography education in the SLTA curriculum, to improve the teaching package whenever necessary and publish books on geography topics.

    Full Text Available Sejalan dengan Perpres No.5/2010, PTRKN-BATAN mengembangkan dua varian desain konseptual reaktor daya maju kogenerasi, yaitu RGTT200K dan RGTT200KT. Energi termal pada kedua sistem reaktor ini dipasok oleh teras reaktor berbahan bakar bola dengan daya termal 200 MWt. Komposisi geometri dan struktur teras didesain agar dapat menghasilkan keluaran pendingin gas helium bertemperatur 950OC sehingga dapat digunakan untuk produksi hidrogen dan atau unit industri proses lainnya secara kogeneratif. Luaran gas helium bertemperatur sangat tinggi ini akan menimbulkan tegangan termal pada bola bahan bakar yang mengancam integritas sistem pengungkungan produk fisi di dalamnya. Oleh karena itu perlu dilakukan analisis termal-aliran untuk mengetahui distribusi temperatur dan aliran pendingin gas helium dalam kisi bahan bakar bola. Salah satu cara terbaik untuk melakukan analisis termal-aliran adalah dengan pemodelan tiga dimensi menggunakan perangkat lunak komputasi dinamika fluida (computational fluid dynamics yang teruji. Dalam penelitian ini digunakan perangkat lunak FLUENT 6.3. Analisis termal aliran pada kisi bola bahan bakar dilakukan dengan memodelkan dinamika fluida pendingin dengan perpindahan panas kombinasi tiga moda, konduksi, konveksi dan radiasi, serta mempertimbangkan adanya turbulensi aliran gas. Model Discret Ordinate dan Reynolds-Averaged Navier-Stokes (RANS masing-masing digunakan dalam perhitungan perpindahan panas radiasi dan turbulensi. Dari distribusi temperatur bola bahan bakar hasil pemodelan CFD dengan aliran turbulen pada pendinginnya diketahui bahwa temperatur maksimum bahan bakar bola mencapai 1036,1OC.

    Full Text Available Pada saluran transmisi diperlukan metode deteksi lokasi gangguan yang akurat dan cepat untuk mengurangi waktu pencarian, sehingga mempercepat proses perbaikan. Dengan menggunakan kombinasi metode Transformasi Park dan Adaptive Neuro Fuzzy Inference System (ANFIS, dapat dideteksi jarak lokasi gangguan secara langsung setelah terjadinya gangguan dengan cara menganalisa gelombang berjalan pada saluran transmisi. Saat terjadi gangguan, akan menyebabkan timbulnya gelombang berjalan yang berupa tegangan dan arus. Tegangan dan arus ini akan ditransformasikan oleh transformasi park pada kedua ujung saluran untuk mendapatkan waktu kedatangan gelombang berjalan, yang mana terdapat perbedaan waktu pada tiap ujung saluran dikarenakan adanya perbedaan jarak yang ada. Perbedaan waktu ini akan di input kedalam ANFIS untuk mendapatkan jarak lokasi gangguan. Dengan membandingkan jumlah nilai keanggotaan dan pemilihan input, maka diperoleh desain ANFIS terbaik adalah dengan jumlah nilai keanggotaan (MF 5 serta input perbedaan waktu ∆tV dan ∆tI (V dan I dengan nilai Mean Absolute Error (MAE sebesar 1,33.

    Full Text Available Proses chemical milling merupakan proses non traditional yang mampu mengurangi dimensi benda, apabila pada proses traditional machine sulit dilakukan. Akan tetapi kelemahan dari proses chemical milling adalah terjadi pengikisan permukaan, sehingga menyebabkan permukaan menjadi kasar. Kekasaran permukaan akibat proses chemical milling akan menimbulkan konsentrasi tegangan, dan hal itu berakibat timbul initial crack, sehingga akan mempercepat laju perambatan retak. Keberhasilan proses chemical milling juga sangat ditentukan oleh larutan etsa serta jenis maskant yang digunakan. Larutan etsa yang biasa digunakan untuk proses chemical milling adalah: NaOH, Na2S, HCl, dan HNO3. Sedangkan bahan maskant yang digunakan meliputi neoprene, polyvinilcloride, dan polyethiline.

Direktorat Jeneral Pendidikan Tinggimenyatakan bahwa terdapat 21 perguruan tinggi negeri dan 7  perguruan tinggi swasta yang didaulat sebagai pelaku plagiarism. Pelaku plagiarisme dalam hal ini jelas besar pasak daripada tiang.Demosi sampai dengan moratorium pengangkatan profesor untuk institusi pelaku plagiarism jelas merupakan sesuatu yang sangat merugikan. Artikel ini mencoba untuk meninjau, bagaimana para pelaku plagiarism dari sudut pandang etika liberalism, yang sangat mennyanjung tinggi kebebasan individual. Dari hasil kajian, ternyata, dengan mengambil pendapat Nozick sebagai tokoh kebebasan individu sekalipun, perilaku plagiarism tetaplah sebuah tindakan yang melanggar prinsip-prinsip keadilan.

    Full Text Available Sumber energi yang berasal dari fosil ( migas merupakan sumber bahan bakar yang tidak dapat diperbaharui. Dimasa sekarang kebutuhan energi sangat meningkat dikarenakan jumlah penduduk semakin banyak dan revolusi Industri yang menuntut sumber energi semakin tinggi. Hal tersebut merupakan permasalahan yang sangat komplek dikarenakan bahan bakar migas semakin menipis. Pemecahan masalah diatas dapat diatasi dengan cara mencari sumber energi alternatif yang dapat diperbaharui. Salah satunya dengan memanfaatkan limbah pertanian yang diubah menjadi arang dengan proses pirolisa kemudian dijadikan briket. Pada pengujian ini penulis hanya menggunakan daun mahoni dan sekam padi sebagai bahan baku briket. Hasil yang didapat menunjukkan penggunaan briket sekam padi lebih optimal dibandingkan daun mahoni. Pada pemakaian sekam padi membutuhkan waktu 15 menit untuk mendidihkan air sedangkan daun mahoni membutukkan waktu 20 menit. Hal ini disebabkan suhu yang dihasilkan sekam padi lebih tinggi sehingga air cepat mendidih. Sekam padi mengandung selulosa yang lebih tinggi dibanding daun mahoni sehingga proses pembakaran lebih cepat.

    Full Text Available Pada penelitian ini telah dilakukan proses pembuatan fotokatalis TiO2/resin, TiO2/zeolit dan TiO2/karbon aktif yang selanjutnya dikarakterisasi dengan XRD dan Energi Band Gap (Eg. Karakterisasi XRD bertujuan untuk mengetahui telah terbentuknya fotokatalis. Sedangkan karaktererisasi Energi Band Gap (Eg bertujuan untuk mengetahui tingkat celah energi pada masing-masing fotokatalis dimana semakin tinggi harga Energi Band Gap maka efektivitas fotoreduksi akan semakin tinggi. Hasil dari karakterisasi XRD menunjukkan bahwa fotokatalis TiO2-resin, TiO2-zeolit, dan TiO2/karbon aktif telah terbentuk, sedangkan hasil energi band gap untuk TiO2/zeolit sebesar 3,608 eV, TiO2/resin sebesar 3,38 eV, sedangkan TiO2/karbon aktif adalah 3,48 eV. Didasarkan pada harga Eg tersebut diharapkan aktivitas fotokatalis TiO2/zeolit lebih tinggi daripada fotokatalis yang lain. Pengujian aktivitas fotokatalis dilakukan dengan mereaksikan 50 mg masing-masing fotokatalis untuk mereduksi 50 mL larutan Hg (II 5 ppm yang disinari oleh sinar matahari sebagai sumber cahaya dengan variasi waktu penyinaran (1,2,3,4,5 dan 6 jam. Dari hasil penyinaran menunjukkan bahwa semakin tinggi waktu penyinaran semakin tinggi % Hg tereduksi, dalam penelitian ini efektivitas fotokatalis terbaik adalah TiO2/zeolit dengan efektivitas fotoreduksi pada penyinaran 6 jam sebesar 98,5%. Pada tahap ini juga dipelajari pengaruh konsentrasi Ion Hg (II (0; 2,5; 5; 10; 20; dan 25 dengan waktu penyinaran 6 jam. Data yang diperoleh menunjukkan semakin tinggi konsentrasi awal ion Hg, semakin rendah efektivitas fotoreduksinya.
