	<dc:description xml:lang="en-US">Electrical energy needs in Indonesia is estimated to continue growing by 4.6% per year, and if there is nothing to be done to increase the production of electric energy, this figure will increase threefold by 2030. Microbial Fuel Cells (MFC) is one way to produce alternative electric energy by utilizing organic material as a substrate for bacterial metabolic activity that generate electricity. The aim of this study is to examine lactose bioelectricity in a parallel circuit MFC system using Lactobacillus bulgaricus to generate electrical energy. The principle of this study is bioelectrochemistry which is the chemical energy change into electrical energy involving redox reactions by utilizing microbes. This study used a dual chamber MFC system with salt bridge as a connector and conductor of protons from the cathode compartment to the anode compartment. An anode compartment contained the bacteria Lactobacillus bulgaricus and lactose substrate, while the cathode compartment contained electrolyte solution KMnO4 0.2 M and phosphate buffer solution with pH = 7. This study used a single circuit, parallel circuit 1 with 2 cells, and a parallel circuit 2 with 3 cells which were oriented to enlarge the produced electricity current. Bioelectricity of lactose produced power in a single series, parallel 1 and parallel 2 respectively were 72.58 x10-6 mWatt; 155.77 x10-6 mWatt; 270.28 x10-6 mWatt where the power generated was proportional to the parallel circuit electric current. Hence by the same potential difference, the power magnitude in parallel circuit 1 approached twice to the single circuit and the power magnitude in parallel circuit 2 approached three times to the single circuit</dc:description>

	<dc:description xml:lang="en-US">Mammography is a radiographic examination to detect breast cancer earlier. However, the usage of radiation with low kVp can cause high dose and this becomes the reason why monitoring the dosage during the mammography process is an important thing to do. One of the techniques to monitor the radiation level is done based on the Entrance Skin Exposure (ESE) value. This research was aimed to determine the ESE value using molybdenum (Mo) and rhodium (Rh) as the filter at Mammomat 1000 mammographics system.The research was started by measuring the consistency of the X-ray tube voltage (kVp ). After that, the ESE value at the target/filter Mo/Mo and Mo/Rh was measured using a Barracuda Multi Purpose Detector (MPD). The tube voltage during the research was 26, 28, and 30 kVp with fixed electrical current-time 100 mAs. The result shows that ESE value resulted at the target/filter Mo/Mo and Mo/Rh is tolerable, except at tube voltage 30 kVp with target/filter Mo/Mo. The comparison of ESE value shows that Mo/Rh has lower ESE value than Mo/Mo.   Keywords: Entrance Skin Exposure (ESE), mammography, Barracuda Multi Purpose Detector (MPD)         Pemeriksaan mammografi merupakan tindakan efektif dalam mendeteksi adanya kanker payudara sejak dini. Namun demikian, penggunaan teknik radiasi dengan kVp rendah pada mammografi dapat menyebabkan dosis tinggi. Oleh karena itu, pemantauan dosis pada pemeriksaan mammografi sangat penting dilakukan. Salah satu teknik pemantauan dosis radiasi dapat dilakukan dengan nilai Entrance Skin Exposure (ESE). Penelitian ini bertujuan untuk menentukan nilai ESE dengan filter molybdenum (Mo) dan rhodium (Rh) pada pesawat mammografi Mammomat 1000. Penelitian diawali dengan pengukuran konsistensi keluaran tegangan tabung sinar-X (kVp output). Selanjutnya dilakukan pengukuran nilai ESE pada target/filter Mo/Mo dan Mo/Rh dengan menggunakan Multi Purpose Detector (MPD) merek Barracuda. Tegangan tabung yang digunakan dalam penelitian yaitu 26, 28 dan 30 kVp dengan arus-waktu tabung tetap yaitu 100 mAs. Hasil penelitian menunjukan bahwa nilai ESE yang dihasilkan pada target/filter Mo/Mo dan Mo/Rh masih berada dalam batas toleransi yang direkomendasikan, kecuali pada pada tegangan tabung 30 kVp untuk Mo/Mo. Hasil perbandingan nilai ESE menunjukan bahwa Mo/Rh memiliki nilai ESE yang lebih rendah dibandingkan dengan Mo/Mo.   Kata kunci : Entrance Skin Exposure (ESE), mammografi, Multi Purpose Detector (MPD) Barracuda. </dc:description>

Similarly, the current density at the tip of the sharp needle is higher than at the ring. The value of the electric field and current density depends on geometric form, especially radius of the hyperbola, radius of the ring, and the distance between the electrodes.

	<dc:description xml:lang="en-US">Peningkatan produksi susu dapat dilakukan melalui program cow replacement dengan pemeliharaan pedet yang optimal sebelum disapih. Hal ini dapat dicapai dengan pemberian pakan starter (calf starter dan sumber serat) bersama susu atau susu pengganti setelah lahir untuk mempercepat perkembangan rumen. Penelitian ini dilakukan dengan tujuan mengkaji penggunaan susu bubuk kedaluwarsa sebagai binder dalam complete calf starter (CCS) dan pengaruhnya terhadap perkembangan retikulo-rumen pedet pra sapih. Materi yang digunakan jerami jagung, jagung kuning, bungkil kedelai, dedak halus, premix dan pedet PFH pra sapih umur 1-2 minggu, bobot badan ±32 kg. Rancangan penelitian yang digunakan adalah rancangan acak lengkap terdiri dari 3 perlakuan. Perlakuan: I. Pellet 100% CCS (tanpa binder) (P0); II : Pellet 90% CCS + 10% susu bubuk kedaluwarsa (P10) ; III: Pellet 80% CCS + 20% susu bubuk kedaluwarsa (P20). Variabel yang diamati adalah kualitas kimia, fisik organoleptik (hardnees dan durability)  dan kualitas biologis (konsumsi, pertambahan bobot badan harian (pbbh), kadar gula dan VFA darah).  Data diolah dengan analisis variansi dilanjutkan dengan uji ganda Duncan. Uji biologis pada pedet umur 3 minggu, menghasilkan konsumsi, pbbh, konsentrasi gula dan VFA darah masih dalam kisaran normal.  Disimpulkan bahwa penggunaan susu bubuk kadaluwarsa hingga 20% dalam CCS dapat diberikan pada pedet PFH umur 2 minggu dan menghasilkan  indicator perkembangan rumen pedet yang baik</dc:description>

	<dc:description xml:lang="en-US">Pengendalian populasi nyamuk Aedes aegypti sangat penting dalam rangka pencegahan terjadinya wabah penyakit demam berdarah. Beberapa bakteri memiliki aktivitas kitinolitik sehingga berpotensi digunakan sebagai agen biokontrol terhadap nyamuk Aedes aegypti, karena komponen eksoskeleton larva nyamuk tersebut tersusun dari bahan kitin.Tujuan dari penelitian ini adalah untuk mendapatkan isolat bakteri kitinolitik akuatik lokal yang dapat digunakan sebagai biokontrol larva nyamuk Aedes aegypti.  Bakteri kitinolitik diisolasi menggunakan media selektif agar kitin. Sumber isolat diperoleh  dari berbagai sampel air yang diperoleh dari daerah Klaten, Boyolali dan Jepara. Isolat yang diperoleh diseleksi untuk mendapatkan isolat dengan aktivitas tinggi. Uji aktivitas bakteri terhadap larva nyamuk menggunakan media air mineral. Hasil penelitian diperoleh satu isolat dengan kode B6 yang mampu menyebabkan kematian larva nyamuk sebesar 97% dalam waktu 108 jam. Isolat ini berpotensi digunakan sebagai agen  bioinsektisida untuk pengendalian larva nyamuk A. aegypti.   Keywords: Bakteri kitinolitik, demam berdarah, Aedes aegypti, biokontrol</dc:description>

	<dc:description xml:lang="en-US">Symptoms of Diabetes Mellitus (DM) or diabetes could be indicated by measuring blood sugar levels in the body. One of the health technology to detect blood sugar in non-invasive is to utilize the absorption of laser light and oxymeter sensor capable of generating a voltage change on a variety of fluid medium. This study has been designed using the blood sugar measuring device microcontroller ATMega 8535 as a minimum system in controlling the value of output in the form of data digital. System/equipment to be fabricated in this study is a non-invasive method (without injuring the patient's body when taking a blood sample) to determine the blood sugar content by exploiting the physical properties of absorption of laser sensors on a variety of blood sugar content. To improve the quality of the test data used 8-bit microcontroller that is capable of separating the output data 256 bits (binary). Each of these bit values can be used to replace manual sensor test results that have analogue voltage output of the data. This analogue data will then be converted to analogue to digital converter (ADC) into digital values are displayed in the liquid crystal display (LCD) that is directly readable by the measured/patients in a short period of time less than 5 minutes. The results of the research can be developed into a national program providing portable medical test equipment is cheap and movable.

ZnO dilapiskan pada karbon aktif dengan memasukkan karbon aktif ke dalam larutan ZnO, kemudian dipanaskan pada temperatur 100oC selama 3 jam.  Mikrostruktur dan komposisi atom ZnO:KA diamati menggunakan scanning electron microscope (SEM) yang terintegrasi dengan energy dispersive x-ray spectroscope (EDX).  Citra SEM menunjukkan bahwa  ZnO telah berhasil dilapiskan pada permukaan KA.  Proses fotokatalis dilakukan pada penjernihan dan reduksi bau busuk air kali Banger dengan pemberian radiasi sinar UV.  Fotokatalitik ZnO:KA diuji melalui pengukuran total dissolved solid (TDS) dan biological oxygen demand (BOD).  Penurunan TDS air  kali Banger yang dijernihkan menggunakan sinar UV dan ZnO:KA lebih rendah dibandingkan dengan media lainnya. Kombinasi antara ZnO dan KA yang disinari UV juga menurunkan BOD air limbah kali Banger. Hasil tersebut menunjukkan bahwa ZnO:KA dapat digunakan untuk proses penjernihan air.   Keywords:ZnO,Karbon Aktif, fotokatalis, penjernihan air, kali Banger</dc:description>

	<dc:description xml:lang="en-US">Bioetanol sebagai sumber energi alternatif baru dapat dihasilkan dari degradasi selulosa secara enzimatis. Proses enzimatis degradasi selulosa menggunakan enzim termostabil yang dihasilkan oleh bakteri termofilik selulolitik. Kompos diketahui merupakan habitat alami bakteri termofilik selulolitik. Eksplorasi sumber bakteri baru penghasil enzim selulase termostabil untuk mengoptimalkan potensi kompos. Isolasi bakteri termofilik selulolitik dari kompos dan identifikasi fenotipik dan genotipik untuk mengetahui profil dan perkiraan jumlah bakteri dari komunitas bakteri telah dilakukan. Hasil penelitian diperoleh isolat komunitas bakteri termofilik selulolitik kompos yang mampu tumbuh pada media CMC. Identifikasi fenotipik menghasilkan lima kenampakan koloni bakteri serta tiga bentuk morfologi bakteri. Data SSCP menunjukkan tiga profil komunitas bakteri dan ada sekitar sembilan spesies yang tumbuh baik pada media CMC. Korelasi kedua identifikasi membuktikan bahwa adanya komunitas bakteri termofilik penghasil enzim selulase pada kompos termofilik.   Kata kunci: bakteri selulolitik, kompos termofilik, SSCP </dc:description>

	<dc:description xml:lang="en-US">ABSTRAK-Polimer sintetik sebagian besar dibuat dari bahan tambang sepeti minyak bumi yang tidak dapat diperbaharui (non renewable) dan non biodegradable. Sehingga diperlukan usaha-usaha untuk membuat polimer biodegradable, seperti polimer ester asam lemak karbohidrat. Minyak nabati seperti minyak biji kapuk merupakan bahan terbarukan yang dapat diubah menjadi metal ester asam lemak dan sangat berpotensi sebagai bahan baku berbagai macam industry. Senyawa ester asam lemak selulosa (FACE) dapat disintesis dari metil ester asam lemak (FAME). Tujuan penelitian ini adalah mengetahui pengaruh temperature reaksi tertadap sintesis FACE menggunakan katalis Na2CO3.  Penelitian ini dilakukan dalam beberapa tahap, diawali dengan penurun kadar asam lemak bebas (FFA) dengan metode ekstraksi pelarut menggunakan etanol. Analisis GC-MS untuk mengetahui komposisi asam lemak penyusunnya. Kemudian dilakukan sintesis FAME dengan katalisator NaOH. Tahap selanjutnya adalah sintesis FACE  dari FAME dan selulosa, sintesis FACE  ini menggunakan katalis Na2CO3 dalam pelarut metanol dengan variasi temperatur 125oC, 130oC, 135oC, 140oC, 150oC selama 4 jam. FACE yang terbentuk dianalisis menggunakan spektrofotometri FTIR untuk mengetahui derajat transesterifikasinya. Bilangan asarn minyak biji kapuk turun dari 6,65 menjadi  0,665. Berdasarkan data GC-MS dan hasil fragmentasi dari masing-masing puncak  dapat diketahui bahwa asam lemak penyusun trigliserida minyak biji kapuk ialah asam linoleat (36,53 %), asam palmitat (20,00 %), asam oleat (18,00 %), dan asam stearat (3,52 %). Rendemen FAME yang dihasilkan sebanyak 17,0538 g dari 20 gram minyak  biji kapuk ldentifikasi FACE yang terbentuk menggunakan FTIR  ditunjukkan dengan munculnya puncak 1743 cm-1 (C=O) yang  diperkuat dengan puncak C-O ester pada 1112 cm-1. FACE yang dihasilkan memiliki derajat transesterifikasi sebesar 0,6048 untuk temperature  130 oC dan 0,6762 untuk temperatur 135 oC. Temperatur optimum sintesis FACE dengan katalis Na2CO3 adalah antara 130 oC – 135 oC. Keywords:  transesterifikasi, s elulasa, Na2CO3, FACE</dc:description>

	<dc:description xml:lang="en-US">Carbon nanotubes have been modified by mass percentage variation of LiCl using reflux method. Mass percentage variation used in this study was 0, 1, 5, and 15%. The purpose of this study was to determine the effect of LiCl dope on the electrical conductivity of carbon nanotubes. This research was used reflux method by heating at 80°C for 24 h. The products produced were in the form of CNTs / LiCl dry powders. The characterization results of FT-IR spectroscopy showed that there was a Li-O bond group in the addition of 1, 5, and 15% LiCl while XRD characterization results did not show any diffraction of lithium chloride. The results of this study showed an increase in electrical conductivity at 15% addition of LiCl which was of 2.69 x 10-3 S/m. Electrical conductivity in the addition of 1% and 5% LiCl decreased (1.17 x 10-6 S/m and 2.64 x 10-6 S/m) from CNTs/LiCl 0% (3.68 x 10-6 S/m) due to the influence of the PVA high resistivity used as an adhesive in the pellets fabrication.</dc:description>

	<dc:description xml:lang="en-US">Di  dalam  dunia  medis,  penyembunyian  informasi  untuk perlindungan  hak  cipta sangat  diperlukan.  Teknik  penyembunyian  informasi  biasa  disebut  dengan watermarking. Metode yang digunakan adalah dengan menyisipkan pesan teks ke dalam sebuah data citra medis. Perlindungan informasi di dalam data citra medis seorang pasien perlu dilakukan agar tidak terjadi kesalahan informasi kepemelikan data  medis  pasien  satu  dengan  yang  lainnya.  Informasi  yang  disembunyikan  di dalam  citra  medis  berupa  teks  yang  sebelumnya  telah dilakukan  enkripsi  atau pengacakan pesan. Salah satu metode untuk menyembunyikan pesan teks adalah dengan memanfaatkan  Least Significant Bit  (LSB), yaitu dengan mengubah nilai bit  terakhir  pada  citra  medis.  Karena  hanya  bit-bit terakhir  yang  diubah,  maka citra medis yang telah tersisipi pesan sangat miripdengan citra aslinya, perubahan nilai-nilai  piksel  pada  citra  medis  tidak  begitu  terlihat.  Untuk  mengekstrak kembali pesan teks yang disisipkan menggunakan private key (kunci rahasia) yang sebelumnya telah ditentukan secara acak. Citra medis dan pesan teks hasil ekstrak sama dengan citra medis dan pesan teks sebelum dilakukan penyisipan.

	<dc:description xml:lang="en-US">Tanaman kedelai (Glycine max (L) Merrill) merupakan tanaman yang sudah dikenal masyarakat dan memilik potensi besar untuk dikembangkan. Tanaman kedelai termasuk tanaman legum yang pada akarnya terdapat bintil akar yang merupakan simbiosis antara akar dengan bakteri Rhizobium japonicum. Bintil akar berfungsi untuk mengikat unsur nitrogen bebas. Selain itu juga dapat menyuburkan tanah karena dapat menghemat penggunaan Nh3 yang tersedia ditanah dan penyediaan unsur nitrogen ke tanah. Tanaman kedelai agar tumbuh subur dan kaya bahan organik. Bahan organik yang digunakan dalam penelitian ini adalah jeramipadi yang merupakan limbah organik yang mempunyai rasio C/N tinggi. Jerami padi mengandung gula, pati, selulose, hemiselulose, pektin, lignin, lemak dan protein. Jerami padi jumlahnya melimpah dan biasanya dibakar dan dibenamkan kedalam sawahdan terjadi dekomposisi. Selama proses dekomposisi terjadi aminasi, amonifikasi, dan nitrifikasi. Petani biasanya menanam kedelai setelah ditanami padi sebelum kemudian ditanami padi lagi tapi belum diketahui berapa lama inkubasi jerami padi berpengaruh menguntungkan dalam pembentukan bintil akar tanaman kedelai. Diharapkan dengan masa inkubasi yang berbeda dapat diketahui tingkat dekomposisi jerami padi yang berpengaruh terhadap pembentukan bintil akar. Tujuan dari penelitian ini adalah untuk mengetahui pengaruh pemberian jerami padi pada masa inkubasi yang berbeda pada pembentukan bintil akar tanaman kedelai (Glycine max (L) Merrill)  dan masa inkubasi jeramiyang berpengaruh paling baik terhadap pembentukan bintil akar tanaman kedelai. Rancangan yang digunakan adalah RAL dengan faktor tunggal dengan perlakuan P1=jerami padi masa inkubasi 15hari, P2=jerami padi pada masa inkubasi 30 hari, P3=jerami padi pada masa inkubasi 45 hari, P0=jerami padi masa inkubasi 15hari (sebagai kontrol). Masing-masing perlakuan dengan 4 ulangan. Parameter yang diamati adalah jumlah bintil akar, persentase bintil akar, berat basah bintil akar dan berat kering bintil akar. Data yang diperoleh dianalisi dengan ANOVA pada taraf uji 5% dan bila terdapat beda nyata dilanjutkan dengan uji Duncan pada taraf uji 5%. Hasil penelitian ini menunjukkan bahwa jerami padi tanpa inkubasi (kontrol) dapat meningkatkan pembentukan bintil akar. Semakin lama masa inkubasi maka semakin menurunkan pembentukan bintil akar tanaman kedelai.   Keywords: Glycine max (L) Merrill, bintil akar, dekomposisi, jerami padi </dc:description>

	<dc:creator>Raharjo, Budi</dc:creator>
	<dc:description xml:lang="en-US">ABSTRAK---Fosfat merupakan nutrient essensial yang diperlukan oleh tanaman dalam pertumbuhan dan perkembangannya. Fosfat sebenarnya terdapat dalam jumlah yang melimpah dalam tanah, namun sekitar 95-99% terdapat dalam bentuk fosfat tidak terlarut sehingga tidak dapat digunakan oleh tanaman Upaya untuk mengatasi masalah ini, salah satunya adalah dengan pembuatan pupuk biologi dengan mikroba pelarut fosfat sebagai agen biofertilizer. Penelitian terdahulu, diperoleh isolat jamur pelarut fosfat dari sampel tanah gambut yang sudah teruji kemampuannya dalam melarutkan fosfat. Penelitian ini bertujuan untuk memperoleh perbandingan isolat jamur pelarut fosfat yang tepat untuk digunakan sebagai formula kultur campur agar dapat melarutkan fosfat secara optimal, meningkatkan kemampuan jamur dalam melarutkan fosfat dengan adanya kerja yang sinergis dari jamur-jamur tersebut, menghasilkan pupuk biologi dengan mikroba sebagai agen biofertilizer. Penelitian dilakukan dengan Rancangan Acak Kelompok dengan perlakuan perbandingan isolat jamur pelarut fosfat yaitu kultur jamur tunggal NSJ 1, NSJ 5, NSJ 6, kultur jamur campur NSJ 1-NSJ 5, NSJ 1-NSJ 6, NSJ 5-NSJ 6, NSJ 1-NSJ 5-NSJ 6 dan kontrol. Kontrol perlakuan digunakan medium uji Pikovskaya tanpa inokulasi jamur. Variabel yang diamati meliputi pH medium kultur, total konsentrasi fosfat yang terlarut. Setiap perlakuan diulang sebanyak empat kali. Analisis data yang digunakan analisis sidik ragam (Ansira) dengan taraf kepercayaan 95 % untuk mengetahui perbedaan antar perlakuan. Jika Fhitung&gt; Ftabel dilakukan uji lanjut dengan uji Duncan. Hasil penelitian menunjukkan bahwa aktivitas pelarutan fosfat pada setiap perlakuan perbandingan isolat jamur F1-F7 secara umum terlihat pada perubahan medium Pikovskaya cair yang semula keruh menjadi bening. Aktivitas pelarutan fosfat mulai terlihat pada awal inkubasi (jam ke 0), dengan konsentrasi fosfat terlarut tertinggi 7,87 ppm yang dihasilkan oleh F5 dan terendah 5,33 ppm oleh F3. Konsentrasi fosfat terlarut menunjukkan penurunan setelah inkubasi 24 jam dengan memperlihatkan penurunan pH dari pH kultur awal inkubasi (jam ke 0) yang tidak begitu drastis. Pada inkubasi 48 jam, semua perlakuan mulai menunjukkan kenaikan konsentrasi fosfat terlarut. Penurunan pH pada inkubasi 48 jam ini dikarenakan adanya aktivitas metabolisme yang mensekresi asam organik. Hasil analisis sidik ragam konsentrasi fosfat terlarut pada inkubasi 48 jam, menunjukkan adanya perbedaan nyata (p&lt;0,05) antar perlakuan perbandingan isolat jamur dalam pelarutan fosfat anorganik. Hal ini berarti bahwa formulasi perbandingan isolat jamur F1-F7 mempengaruhi pelarutan fosfat anorganik. Hasil analisis pada inkubasi 48 jam ini memperlihatkan bahwa perlakuan formulasi F7 paling tinggi dalam melarutkan fosfat dan adanya kerja sinergis dalam meningkatkan pelarutan fosfat.

	<dc:description xml:lang="en-US">Fitoplankton merupakan produsen primer perairan, sehingga keberadaannya sangat penting untuk tingkatan trofik di atasnya. Komunitas fitoplankton sangat ditentukan oleh kualitas perairan, sehingga fitoplankton dapat digunakan sebagai bioindikator kualitas perairan. Tekanan lahan di bagian hulu merupapan problem utama Danau Rawapening.Volume air Danau Rawapening cenderung menurun sebagai akibat sedimentasi yang cukup tinggi, sehingga mengganggu fungsi utamanya. Penelitian ini bertujuan mengkaji komunitas fitoplankton Danau Rawapening. Pengambilan sampel dilakukan pada 7 lokasi di Danau Rawapening. Identifikasi fitoplankton dilakukan menggunakan SRC dan mikroskup perbesaran 400 – 1.000 kali. Dijumpai 58 spesies fitoplankton dengan dominansi Bacillariophyta. Berdasarkan keanekaragaman fitoplankton, maka ekosistem Danau Rawapening kurang stabil – cukup stabil. Dominannya Aulacoseira granulata mengindikasikan kondisi eutrofik danau. Penelitian perlu dilanjutnya pada musim dan waktu yang berbeda.   Keywords: fitoplankton, Danau Rawapening, eutrofik, bioindikator</dc:description>

	<dc:creator>Hidayat, Jafron W.</dc:creator>
	<dc:description xml:lang="en-US">Kawasan hutan mangrove mengalami tekanan dan perusakan yang serius, sehingga harus direhabilitasi dengan penghijauan. Gangguan yang penting dalam penghijauan diantaranya adalah hama wideng (Sesarma spp).   Wideng menyerang bibit dan tanaman mangrove serta membuat lubang pada pematang tambak. Hal tersebut menyebabkan program wanamina kurang diterima masyarakat. Perlu dilakukan pengelolaan sedemikian rupa populasi wideng dapat ditekan/ dikurangi secara buatan dengan melibatkan masyarakat. Oleh karena itu perlu dilakukan penelitian pengendalian wideng melalui pendekatan co-manajemen. Tujuan penelitian adalah mengetahui kegiatan masyarakat yang berkaitan dengan kegiatan penghijaun dan antisipasi teknis terhadap gangguan hama wideng. Penelitian juga ditujukan untuk mengidentifikasi potensi pengendalian alternatif yang memungkinkan. Penelitian dilakukan di desa Tapak Tugurejo, Semarang. Objek kajian difokuskan pada masyarakat yang memiliki kepedulian  terhadap konservasi hutan mangrove. Data penelitian diperoleh dengan menggunakan questioner dan interview mendalam terhadap anggota kelompok masyarakat serta menggunakan sejumlah dokumen dan pustaka. Data dianalisis secara deskriptif eksploratif menggunakan data yang disajikan dalam tabel. Hasil penelitian memperlihatkan bahwa kelompok masyarakat Desa Tapak telah melakukan berbagai kegiatan teknis untuk penghijauan mangrove dan pengendalian gangguan wideng. Kegiatan meliputi pembuatan petak pembibitan, memisahkan lokasi pembibitan berdasarkan jenis bibit, memproduksi bibit yang lebih tua, menggunakan pestisida organik dan perlindungan  propagul. Praktek tersebut belum menjadi pedoman teknis bagi kelompok, hanya bersifat fleksibel sesuai kebutuhan. Kelompok masyarakat masih berpotensi menerapkan pengendalian alternatif, yaitu dengan mengatur waktu dan lokasi tanam, menggunakan bibit yang spesifik secara umur dan jenis, memadukan dengan kegiatan budidaya Scylla spp dan membatasi penangkapan kepiting secara waktu dan tempat. Kombinasi kesemua teknik di atas dapat menekan gangguan hama, melestarikan hutan mangrove dan menghasilkan produk bernilai ekonomi. Ujung akhir dari rangkaian kegiatan teknis tersebut adalah kesejahteraan dan kelestarian lingkungan secara menyeluruh.   Keywords: Pelestarian mangrove, wideng, masyarakat</dc:description>

	<dc:description xml:lang="en-US">Mushrooms naturally grows on logs that have experienced weathering. Raw materials of mushroom growth media containing plenty of wild microbes, especially wild mold on sawdust media. Sterilization conducted did not prevent the occurrence of contamination. This study aim was to determine the types of contaminant molds in cultivated mushroom growth media (bag logs), as well as determine their cellulolytic performance. Mushroom growth media (bag log) samples were taken from three mushroom cultivation locations. Mold isolates obtained were identified by their macroscopic and microscopic characteristics. Test the mold cellulolytic performance was conducted by measuring the ratio of hydrolysis zone with the diameter of mold on CMC (Carboxy Methyl Cellullose) media. The isolation and identification results of contaminant molds consisted of mold isolates which could be grouped into 7 genus which were Aspergillus, Penicillium, Paecillomyces, Trichoderma, Rhizopus, Fusarium and Syncephalastrum. The cellulolytic performances of mold on CMC media showed that Aspergillus flavus has the greatest cellulolytic ability.</dc:description>

	<dc:creator>Sunarno, Sunarno</dc:creator>
	<dc:description xml:lang="en-US">ABSTRAK---Agregasi atau penggabungan embrio untuk menghasilkan embrio dengan kualitas unggul dapat dilakukan pada tahap awal perkembangan embrio sampai sebelum embrio mencapai tahap morula kompak. Agregasi embrio dapat dilakukan dengan beberapa cara, yaitu: agregasi antar embrio tanpa zona peluzida menjelang proses kompaksi dan agregasi embrio tahap aawal yang masih mempunyai blastomer dengan konfogurasi longgar satu sama lain. Penelitian ini bertujuan untuk mengetahui nilai viabilitas embrio hasil agregasi pada medium KSOMaa melalui proses agregasi embrio tahap pembelahan 8 sel. Hasil penelitian menunjukkan bahwa medium KSOMaa mampu menstimulasi pertumbuhan dan perkembangan embrio tahap pembelahan 8 sel sehingga dihasilkan embrio hasil agregasi dengan nilai viabilitas yang tinggi. Untuk mendukung proses agregasi sehingga dihasilkan embrio dengan nilai viabilitas yang tinggi dalam sistem kultur in vitro, harus memperhatikan beberapa faktor, antara lain sumber gas CO2, nutrisi (medium), substrat (wadah) dan suhu inkubasi. Dalam mempersiapkan medium juga harus diperhatikan beberapa hal penting, seperti sumber air yang digunakan sebagai pelarut, sifat fisik seperti osmolaritas, pH serta komposisi media yang disesuaikan dengan kebutuhan pertumbuhan dan perkembangan embrio.   Keywords: kultur in vitro, agregasi, embrio, viabilitas, mencit (Mus musculus)</dc:description>

	<dc:description xml:lang="en-US">The research was conducted to process 2D seismic data by Pre Stack Depth Migration (PSDM) method on the field “AV”. The purpose of this study was to determine the appropriate interval velocity model to manage the PSDM methods work. Interval velocity model obtained from the initial estimate using coherency inversion velocity model is usually not convergent. Interval velocity model should be improved through several stages in order the estimated speed could be closer to the actual speed value. Some initial interval velocity model parameters should be improved to be more sensitive to lateral velocity variations for PSDM work. The method used to improve the velocity model was a horizon-based tomography using the ray tracing concept. These methods improved the layer speed and reflector geometry to produce a new interval velocity model. Model errors should be corrected by residual move out analysis. The best analysis obtained was from the fifth iteration to eliminate errors and flatten depth gathers. The proper value of the speed produced good quality images. The results of this research was PSDM Section or PSDM cross-section. PSDM cross-section has a good image quality to represent the geological structures in the earth's sub surface.</dc:description>

Pemanfaatan Teknologi Informasi dan Komunikasi (TIK) pada EC lebih berhasil dibandingkan dengan pemanfaatan TIK pada pemerintahan dalam hal ini EG. Keberhasilan EC  inilah  yang  akan  digunakan  oleh  pemerintahan  untuk  menerapkan  paradigm  EC  ke  dalam  EG,  dengan mengadopsi  konsep,  proses,  dan  teknologi  yang  diterapkan  pada  bisnis. Kajian  ini  dilakukan  secara  komperatif terhadap dua  fenomena EC dan EG. Pada makalah  ini dibahas  secara empiris mengenai karakteristik persamaan dan perbedaan antara EC dan EG, serta paradigma kekuatan dan kelemahan pada EC untuk diterapkan pada EG. Fenomena  antara  EC  dan  EG  memiliki  banyak  persamaan,  tetapi  pada  prinsipnya  meliliki  perbedaan  secara mendasar terkait mengenai peran bisnis dengan pemerintah.  Kata Kunci : E-Commerce, E-Government, Paradigma, Bisnis, dan Pemerintah    </dc:description>

	<dc:description xml:lang="en-US">  Penelitian tentang destruksi larutan zat warna—remazol black B—dalam upaya penghilangan warna larutan limbah dengan metode elektrolisis menggunakan anoda timbal dioksida telah dilakukan. Remazol black B merupakan pewarna batik dan tekstil yang banyak digunakan pada proses perwarnaan. Pada proses produksi, zat warna ini terbuang ke lingkungan dan mencemari perairan, sehingga diperlukan  upaya untuk memperbaiki lingkungan perairan. Pendekatan elektrokimia merupakan metode alternatif bagi upaya pemecahan masalah lingkungan yang tercemar zat warna seperti remazol blak B. Bahan elektroda merupakan faktor penting pada keberhasilan proses. Pemilihan timbal dioksida (dari aki) sebagai elektroda dilakukan dengan mempertimbangkan sifat bahan ini dalam sistem eletrolisis, stabil (inert) dan diharapkan memiliki efek katalisis dalam proses destruksi sehingga mengahsilkan sinergi pada upaya remediasi perairan tercemar dengan pendekatan elektrokimia. Penelitian ini bertujuan untuk menghasilkan larutan tak berwarna setelah perlakuan destruksi elektrokimiawi sampel yang mengandung remazol black B menggunakan elektroda PbO2. Metode ini dilakukan dengan mengelektrolisis larutan remazol black B sebanyak 50 mL dengan potensial 5,5 V selama 120 menit. Setelah elektrolisis larutan sampel dianalisis dengan spektrometri UV-Visibel. Untuk memperoleh data awal, elektrolisis dilakukan terhadap larutan sampel dengan variasi potensial aplikasi dan variasi waktu elektrolisis hingga 120 menit. Pada variasi waktu tersebut, dilakukan pencatatan arus yang mengalir dan pengujian tingkat pengurangan kepekatan zat warna dengan metode Spektrometri UV-Visibel. Sebagai pembanding dan untuk memperoleh daerah kerja dilakukan juga elektrolisis terhadap sistem pelarut. Data penelitian menunjukkan bahwa elektrolisis dengan penggunaan PbO2 sebagai anoda pada elektrodestruksi larutan remazol black B telah berhasil menurunkan intensitas zat warna tersebut hingga 99,69 %. Penurunan intensitas ini menunjukkan bahwa elektrodestruksi larutan zat warna remazol black B telah berlangsung. Perubahan intensitas warna ini disebabkan oleh proses destruksi oksidatif (elektrodestruksi) remazol black  B menjadi molekul-molekul yang lebih sederhana, sehingga larutan menjadi tidak berwarna..   Keywords: elektrolisis, elektrodestruksi, remazol black B, elektroda PbO2, spektrometri UV-Visibel</dc:description>

	<dc:creator>Auliawan, Riky</dc:creator>
	<dc:creator>Cahyono, Bambang</dc:creator>
	<dc:description xml:lang="en-US">Penemuan antidiabet dari suatu senyawa bioaktif atau ekstrak tanaman banyak diarahkan pada mekanisme penghambatan hidrolisis ikatan glikosidis, dan umumnya tertuju pada senyawa fenolik. Tanaman iler (Coleus scutellarioides), yang secara tradisional telah digunakan untuk antidiabetes, dilaporkan mengandung senyawa dari golongan tersebut. Penelitian yang bertujuan membandingkan  aktivitas dari ekstrak daun iler dan ekstrak yang terhidrolisis telah dilakukan dalam riset ini. Penyediaan ekstrak dilakukan melalui maserasi dalam pelarut etanol, dan hidrolisis ekstrak dilakukan dalam suasana asam (HCl 2N). Ekstrak dan hasil hidrolisis dianalisis fenolat total dan aktivitas penghambatan enzim alfa-glukosidase.  Hasil penelitian menunjukkan bahwa ekstrak etanolat daun iler dapat diperoleh dengan rendemen 4,50%. Adanya peningkatan kadar fenolat total rata-rata dari ekstrak setelah dihidrolisis sebesar 23,99 mg GAE/g bobot sampel kering (dari 156,38±0,25 menjadi 180,37±0,260 dapat mengindikasikan bahwa ikatan glikosida pada ekstrak asal telah terhidrolisis oleh HCl. Uji aktivitas penghambatan a-glukosidase terhadap sampel sebelum dan sesudah hidrolisis menunjukkan harga IC50 sebesar 735,67±11,51µg/mL dan 724,33±8,60µg/mL. Secara statistik, nilai aktivitas kedua bahan ini tidak berbeda secara signifikan. Hasil penelitian ini dapat membuktikan bahwa ikatan  glikosida dalam senyawa organik ekstrak daun iler tidak memberikan efek terhadap peningkatan aktivitas penghambatan enzim glukosidase. Kata kunci: Coleus scutellarioides, daun iler, fenolat total, enzim α-glukosidase, hidrolisis ekstrak      The studies of antidiabetic activity of a bioactive compound or plant extract have been directed into the inhibition mechanism of glycoside bond hydrolyses, and generally focused on phenolic compounds. Iler plants (Coleus Scuterllariousdes) that traditionally used as antidiabetic, has been reported containing those compounds. Aim of this study is comparing the activity of Iler leaves extract and their hydrolyzed extracts. The extracts were prepared by ethanol maceration and acid hydrolysis (HCl 2N). Both ethanol and hydrolyzed extracts were analyzed for total phenolic and alpha-glucosidase inhibitory activity. The result showed that the extract yield was 4.50%. The increasing number of total phenolic content after hydrolysis (23.99 mg GAE/g weight of dry samples) indicated that the glycoside bonds in extracts have been hydrolized by HCl. The alpha-glucosidase inhibitory (IC50) of ethanol and  hydrolyzed extracts were 735.67±11.51µg/mL dan 724.33±8.60µg/mL respectively. Statistically, the differences of inhibitory activity of both extracts was not significant. This result proved that the glycoside bond in Iler leaves extract does not enhance the inhibition activity of glucosidase enzyme.

	<dc:description xml:lang="en-US">Many real problems can be represented in the form of multiple linear regression equation. One of those is the relationship between the variables of temperature and altitude of the spontaneous-potential. In order to determine the parameters of the regression equation, the least squares method was used. From here, there was obtained the system of linear equations. In this paper, to solve systems of linear equations, the exact method was used as the exact solution is certainly better than the approached solution. The method used was the QR factorization method. At the QR factorization, the system of linear equations was written in form of matrix equation. Then, the coefficient matrix which the number of rows is m and number of columns is n with linearly independent columns was factored into the matrix Q which has the same size with the matrix A, with orthonormal columns and matrix R was upper triangular. Furthermore, by backward substitution, it could be obtained the exact solution of linear equation system. As verification of this proposed method, a case study was given using data of temperature, altitude, and spontaneous-potential in the geothermal manifestations area, Gedongsongo, Mount Ungaran Semarang. From here, it was obtained the parameters of exact multiple linear regression model which states the relationship between temperature and altitude toward the spontaneous-potential.</dc:description>

	<dc:description xml:lang="en-US">Pemurnian DNA plasmid berbasis silika didasarkan pada fakta bahwa DNA dapat dimurnikan menggunakan fase padat seperti silika dengan adanya denaturan. Adsorpsi DNA pada permukaan silika merupakan alternatif metode pemurnian yang efektif dan efisien dibandingkan metode pemurnian konvensional. Prinsip metode ini adalah pengikatan molekul air oleh denaturan dan adanya ikatan hidrogen antara gugus fosfat DNA dengan gugus silanol (SiOH-) pada permukaan silika. DNA plasmid pUC19 diisolasi dari sel inang E.coli JM109 menggunakan metode lisis alkali dan dimurnikan dengan dua metode, yaitu ekstraksi fenol-khloroform dan kolom silika. Hasil kemurnian DNA plasmid menggunakan kolom dengan silika 5 mg pada konsentrasi urea 6 M sebesar 1,36. Nilai tersebut lebih tinggi dibandingkan hasil pemurnian dengan ekstraksi fenol:kloroform-isoamil alkohol yaitu sebesar 1,28. Variasi konsentrasi urea 5-9 M pada kolom dengan silika gel 5 mg dan 25 mg digunakan untuk mengetahui profil kapasitas urea sebagai agen denaturan pada pemurnian DNA plasmid. Hasil analisis secara spektrofotometri menunjukkan nilai kemurnian DNA plasmid pada konsentrasi urea 6-8 M berada pada kisaran 1,33 dan 1,48.

	<dc:description xml:lang="en-US">ABSTRACT---Salah satu perkembangan utama pada spesifikasi dinamis adalah Error Correction Model (ECM). ECM dapat dipakai untuk menjelaskan mengapa pelaku ekonomi menghadapi ketidakseimbangan (disequilibrium). Secara khusus, Teorema Representasi Gramger menyatakan bahwa ECM dapat dikatakan valid jika memuat himpunan variabel yang memenuhi uji kointegrasi. Pada hubungan keseimbangan antara xt dan yt adalah :   yt = β0 + β1 xt  maka dari penurunan rumus diperoleh Error Correction Model :  	∆ yt= b1 ∆ xt – λ (yt-1 - β0 - β1 xt-1)  + et              	0 &lt; λ &lt; 1  Pada penelitian ini, akan diselidiki faktor-faktor yang mempengaruhi pertumbuhan ekonomi Indonesia pasca krisis moneter, yaitu periode 1997(III) – 2004(IV), sebagai studi kasus. Hasil empiris digunakan untuk menyelidiki efek jangka pendek dan jangka panjang dari variabel-variabel penjelas pada model pertumbuhan ekonomi. Dari hasil analisis diperoleh ECM :  ∆ln(ĝdp)t = 0.004633 – 0.954748∆ln(kre)t + 0.397869∆ln(eks)t + 0.046700 ∆ln(fdi)t + 0.286713∆ln(kre)t-1– 0.183157∆ln(eks)t-1 – 0.360344∆ln(fdi) t-1 +  0.34592ECT   Dan model jangka panjang yang dihasilkan adalah :  ln (ĝdp)t= 0.013418 + 1.828841 ln(kre) + 0.470522 ln(eks) – 0.041697 ln (fdi)   Kata kunci : Model Koreksi Kesalahan, kointegrasi, stasioneritas</dc:description>

	<dc:description xml:lang="en-US">All living cells consist of phospholipids. Phospholipids are known as biosurfactants. Here we report our study of the physico-chemical characteristics of phospholipids derived from coconut endosperm as biosurfactants. We studied the aggregation and emulsification characters. The aggregation proccess was examined by optical microscope. The stability of emulsi formed was montitored at different temperature and pH. Where as emulsification capability was investigated by constructing a ternary diagram. Depending on the amount of phospholipids and additive substances the emulsification capability changes. The coconut phospholipids will form vesicles in various size (polydisperse). We noticed that coconut phospholipids emulsification stability was affected by temperature, pH, and phospholipids composition. It can be concluded that the prospect of phospholipids from coconut endosperm as biosurfactants is promising.   Keywords: coconut phospholipid, emulsification capability, aggregation, ternary diagram, vesicle.</dc:description>

Keanekaragaman hayati seperti jenis-jenis tanaman, hewan, dan mikroorganisme yang ada dan berinteraksi dalam suatu ekosistem sawah sangat menentukan tingkat produktivitas pertanian.  Serangga sebagai salah satu komponen ekosistem sawah memiliki peranan penting dalam jaring makanan yaitu sebagai herbivora, karnivora (predator dan parasitoid), dan detritivora. Di dalam ekosistem sawah terdapat berbagai macam jenis serangga yang hidup dan tinggal di ekosistem sawah tersebut. Penelitian bertujuan untuk mengkaji keanekaragaman serangga dan menganalisis peranan serangga yang ditemukan dalam ekosistem sawah. Penelitian dilakukan di lahan sawah di Kelurahan Pedalangan Kecamatan Tembalang Kota Semarang. Metoda penelitian menggunakan metoda perangkap sumuran (pit fall traps), perangkap lampu (light traps) dan perangkap nampan kuning (yellow tray traps). Hasil yang diperoleh nampak bahwa serangga yang didapatkan dibagi menjadi 4 kelompok berdasarkan peranannya yaitu serangga herbivor, serangga predator, serangga parasitoid dan serangga detritivor. Dari semua jenis serangga yang teridentifikasi maka 49.6% diantaranya adalah serangga herbivor, 46.1% merupakan serangga predator, 3.5% merupakan serangga parasitoid dan 0.6% adalah serangga detritivor. Keanekaragaman serangga yang ditemukan di lahan sawah adalah dengan perangkap sumuran diperoleh 23 spesies dalam 14 famili dalam 8 ordo, dengan perangkap lampu diperoleh 9 spesies dalam 7 famili dari 4 ordo, dengan perangkap nampan kuning diperoleh 8 spesies dalam 6 famili dan 3  ordo.   Kata kunci : keanekaragaman serangga, peranan serangga, ekosistem sawah. Rice ecosystems is an important factor in meeting food needs . Biodiversity such as the types of plants , animals , and microorganisms that exist and interact in a rice field ecosystem will determine the level of agricultural productivity .

	<dc:description xml:lang="en-US">The study on prediction of 2D isodose curves for atbitrary field size has been done. Isodose curve is very useful for plannning and evaluation of doses received by patients in the radiotherapy treatment.  The percentage depth dose (PDD) and dose profiles data for standard field size (square) were obtained from measurements in the Kensaras hospital, Semarang Regency. Dose profiles were taken at a depth of 1.5 cm and a radiation source to skin distance (SSD) of 100 cm. The calculation of PDD data in any field size uses linear interpolation method. While the calculation of the dose profile curve uses the widening, narrowing and weighting interpolation method. Firstly, the calculation of PDD and dose profile for standard field sizes of 3x3, 10x10, 15x15 and 20x20 cm2 were carried out and the results were compared to the measurements. Secondly, the PDD and dose profile for arbitrary field sizes 7x7 dan 13x13 cm2 were calculated. After that, the isodose curves for arbitrary field sizes were generated. The results showed that PDD curves of standard field sizes have maximum deviation values &lt; 5% compared to the measurements. While the dose profile curves for field sizes up from 5x5 cm2 have maximum deviation values approximately 5% which was less than measurement. The profile curve of field size of 3x3 cm2 has maximum deviation value &gt;5%. These results showed that our proposed algorithm was relatively valid. In this study, the PDD, dose profile and isodose curves of arbitrary field sizes 7x7cm2 and 13x13 cm2 were succesfully generated.</dc:description>

Dans) is a medicinal plant species used as anticancer because it contains some flavonoids compounds are chalcones, c-glycoflavonols, chatechin and quercetin. The ability of endophytic bacteria to produce similar bioactive compounds with its host plant is potential source to get flavonoids compounds. This research aims to know ability of endophytic bacteria in produce flavonoids compounds in vitro. Each isolate was fermented in submerged culture with 0.1% soluble starch, 0.5% pepton, and 0.15% yeast extract medium for 5 days, then extracted with ethyl acetate. Flavonoid content of the extract then was tested qualitatively and confirmation test used thin layer chromatography. Qualitative test results showed that crude extract from isolates B4, B5, B10, B17, and B19 positive containing flavonoids. The most potent extract were B10 and B19 tested by thin layer chromatography. Two of these extracts had the same Rf value with quercetin, thus endophytic bacteria from tea mistletoe can produce flavonoids in vitro.</dc:description>

	<dc:description xml:lang="en-US">ABSTRAK---Jika terdapat dua variabel atau lebih dalam Model Vector Autoregressive (VAR) orde p, maka tidak menutup kemungkinan bahwa antara variabel-variabel tersebut saling mempengaruhi. Hubungan ini dapat berupa pengaruh satu arah, dua arab, atau tidak terdapat antar variabel-variabel. Hubungan-hubungan semacam itu disebut hubungan kausalitas. Untuk membuktikan keberadaan hubungan kausalitas dalam suatu model VAR dapat digunakan Uji Kausalitas Granger. Penelitian ini menguji keberadaan hubungan kausalitas antara harga saham dengan kinerja keuangan perusahaan PT Indofood Sukses Makmur Tbk. periode 1998-2005. Penelitian ini akan menyelidiki beberapa  variabel  yang  terlibat dalam model simultan harga saham,  yaitu harga  saham  (Yr)  dan  kinerja kuangan perusahaan  yang  diwakili oleh variabel-variabel Return of Assets atau ROA  (Y2), Debt to Equity Ratio atau DER (Y3), dan Earning Per Share atau EPS (Yr).  Hasil  penelitian menunjukkan  variabel-variabel dalam model tidak stasioner dan terintegrasi pada derajat I, serta residualnya bersifat independen dan terdistribusi normal. Dengan AIC dan SC disimpulkan bahwa masing-masing persamaan memuat 4 lag. Dengan uji kausalitas Granger disimpulkan bahwa terdapat hubungan  satu arah antara variabel harga saham terhadap ROA dan EPS, sedangkanhubungan satu arah juga ditunjukkan variabel DER terhadap harga saham. Hal ini menuqiukkan bahwa antara harga saham dan kinerja keuangan perusahaan tidak terdapat hubungan dua arah.Kata  kunci  : model simultan, Vector Autoregressive (VAR), Uji  Kausalitas Granger, Harga Saham,  Return of Assets  (ROA), Debt to Equrty Ratio (DER), dan Earning Per Share (EPS).</dc:description>

	<dc:description xml:lang="en-US">ABSTRAK---Kayu manis banyak digunakan sebagai obat tradisional., misalnya bagian serbuk kulit kayunya telah digunakan oleh masyarakat di negara tropis termasuk Indonesia sebagai obat antidiabetes. Penelitian secara ilmiah mengenai khasiat tersebut belum banyak dilakukan, sehingga perlu dilakukan penelitian secara ilmiah khasiat antidiabetes melalui uji aktivitasnya terhadap inhibitor enzim alfa-glukosidase. Enzim Alfa-glukosidase (EC 3.2.1.20) merupakan karbohidrase yang mengkatalisis pelepasan glukosa dari ujung nonpereduksi karbohidrat makanan. Pada penderita Diabetes Mellitus (DM), inhibisi terhadap enzim ini menyebabkan penghambatan absorpsi glukosa sehingga menurunkan keadaan hiperglikemia setelah makan. Inhibitor alfa-glukosidase merupakan obat antidiabetes oral yang digunakan untuk mengobati DM tipe 2. Penelitian ini bertujuan untuk mengetahui khasiat serbuk kulit kayu manis sebagai antidiabetes melalui uji inhibitor terhadap enzim  alfa-glukosidase. Penelitian dilakukan dalam beberapa tahap, yaitu penyediaan bubuk kayu manis dan uji penghambatan terhadap alfa-glukosidase. Pada uji penghambatan alfa-glukosidase digunakan enzim alfa-glukosidase dan p-nitrofenil α-D-glukopiranosid sebagai substrat. Reaksi dari substrat  p-nitrofenil α-D-glukopiranosid dengan alfa glukosidase menghasilkan p-nitrofenol, senyawa ini yang diukur intensitasnya. Semakin tinggi intensitasnya semakin tinggi aktivitas alfa glukosidase. Serbuk kulit kayu mampu menghambat alfa glukosidase dalam berbagai konsentrasi.

	<dc:description xml:lang="en-US">ABSTRACT---Tuberculosis (TB) is an infectious disease caused by the bacteria mycobacterium tuberculosis. TB is the number one killer among infectious diseases, and even Indonesia occupies the fifth largest country in the world in this disease problem. Detection of TB disease through clinical symptoms, laboratory tests and thoracic imaging (lung) with x-ray. The research was conducted to determine the histogram and the average value of gray scale image of the thoracic patients suffering from TB and who is not. By knowing the value of the histogram and the mean gray scale this can later be used as additional instructions for medical personnel to diagnose, i.e. to determine whether the patient has TB or not. In this research, the exposure factors was carried out with a tube voltage of 55 kV, tube current 200 mA and time 0.08 s, using of the Computed Radiography (CR). Histogram analysis performed on the Region Of Interest (ROI) that is at the apex of the lung and superior lung lobes contained patches of gloom on the image of the thorax. It was obtained that the image histogram from TB patients shifted to the right or the gray scale pixel values have a higher (brighter). The average value of pixel gray scale image of the patient suffering from tuberculosis at 13,3 and for patients who are suffering from TB at 61,6.Key words: thoracic imaging, Tuberculosis, histogram ABSTRAK---Penyakit Tuberculosis (TB) merupakan suatu penyakit menular yang disebabkan oleh bakteri mycobacterium tuberculosis. TB merupakan pembunuh nomor satu diantara penyakit menular, bahkan Indonesia menduduki negara terbesar kelima di dunia dalam masalah ini. Deteksi penyakit TB dilakukan melalui gejala klinis, uji laboratorium dan foto thoraks (paru-paru) dengan sinar-x. Penelitian inidilakukan untuk mengetahui histogram dan nilai rerata sekala keabuan citra thoraks pasien yang menderitaTB dan yang bukan. Dengan mengetahui nilai histogram dan nilai rerata sekala keabuan ini nantinya dapat dijadikan petunjuk tambahan bagi tenaga medis untuk menegakkan diagnosa, yaitu untuk menentukan apakah pasien menderita TB atau tidak. Dalam riset ini, eksposi dilakukan pada tegangan tabung 55 kV, arus tabung 200 mA dan waktu 0,08 S, serta menggunakan Computed Radiography (CR). Analisis histogram dilakukan pada Region Of Interest (ROI) yaitu pada daerah apeks paru dan lobus superior paru yang terdapat bercak-bercak kesuraman pada citra thoraks. Dari penelitian diperoleh bahwa histogram citra pasien penderita TB bergeser ke sebelah kanan atau mempunyai nilai skala keabuan piksel yang lebih tinggi (lebih cerah). Nilai rata-rata skala keabuan piksel citra pasien yang menderita TB sebesar 136,3 dan tidak menderita TB sebesar 61,6.Kata kunci: pencitraan thoraks, Tuberculosis, histogram</dc:description>

This study aim was to assess the potential of tofu whey as a substrate in the MFC system and to evaluate the effect of agitation speed to the potential difference generated in the MFC system using Lactobacillus bulgaricus. The potential difference in the variation of the substrate was measured against tofu whey, glucose and lactose. The potential difference with agitation speed variation was carried out at speed of 30, 60, 90, 125 and 250 rpm. The highest potential differences in the substrate variation showed relatively similar results, however they were achieved in different times, which the speed was dependent on the complexity of the substrate molecular structure. While the agitation of 90 rpm gave the highest potential difference. These results indicates that tofu whey potential to be used as a MFC substrate.</dc:description>

	<dc:description xml:lang="en-US">Peran mikroorganisme dan fauna tanah dalam menentukan kualitas tanah telah diketahui cukup luas, namun perannya terhadap kapasitas infiltrasi air belum banyak dikaji. Penelitian ini secara umum bertujuan untuk mengetahui pengaruh biostarter berupa inokulan mikroba komersial untuk perbaikan kualitas tanah. Secara khusus penelitian ini bertujuan untuk mengetahui pengaruh produk biostarter terhadap struktur komunitas mesofauna tanah dan laju infiltrasi air serta korelasi antara struktur komunitas mesofauna tanah dengan kapasitas infiltrasi. Penelitian ini menggunakan Rancangan Acak Lengkap faktor tunggal dengan empat perlakuan biostarter yaitu EM4, Bioklin, Mig Dec, dan Orgadec. Periode sampling dilakukan dua kali pada hari ke 30 dan hari ke 50 inkubasi. Hasil penelitian menunjukkan bahwa penambahan biostarter memengaruhi struktur komunitas mesofauna tanah, khususnya berpengaruh positif terhadap kelimpahan Oribatida dan Mesostigmata. Produk Orgadec secara konsisten mampu meningkatkan kelimpahan mesofauna tanah paling tinggi pada  30 hari maupun 50 hari. Laju infiltrasi pada umur inkubasi 30 hari menunjukkan adanya perbedaan yang nyata pada perlakuan Orgadec saja, sedangkan pada umur 50 hari, perbedaan secara nyata ditunjukkan pada perlakuan EM4, Mig Dec dan Orgadec. Secara statistik, total kelimpahan mesofauna tanah dan kelimpahan Oribatida menunjukkan perbedaan yang nyata dengan laju infiltrasi.   Keywords: biostarter, struktur komunitas, mesofauna tanah, laju infiltrasi</dc:description>

	<dc:description xml:lang="en-US">Rawapening lake is the one of national priority 2010 – 2014 that must get safe because the worse condition from eutrofication and water degradation quality. Eutrofication of Rawapening lake caused by nutrients/organic compounds enrichment naturally  or anthropogenically, that signed by higher concentration of  Nitrogene and Phosphate that trigger hydrilla blooming. The blooming of hydrilla disturb Rawapening Lake functions like flood bender, fisheries and tourism. However in another side this plants can be used to heavy metal remediation such as Pb as act of human activities like farming, fisheries, tourism, and home industry around the lake.  There were many researchs to explore hydrilla potention for remediation, but still laboratory scale with under control condition. Because of these, it’s required to do a research to find out fitoremediation potention of hydrilla to remediate heavy metal Pb in Rawapening Lake water and sediment (In – situ) to study its Pb bioaccumulation. Research was start in August – October 2013 used hydrilla in three weeks. That plants was planted in pond 1 m3. It was planted one plant each pond with 100 gram fresh weight and observed each week to calculated the Pb concentration. The parameter was observed is BAF (bioaccumulation factor) Pb sediment. The result is hydrilla has highest BAF value in week two with 97,90%. Hydrilla has potention to remediate heavy metal Pb that contain in sediment and it can harvested in two weeks.   Keywords : Eutrofication, Rawapening Lake, hydrilla, bioaccumulation, fitoremediation.           Danau Rawapening merupakan salah satu danau prioritas nasional 2010 – 2014 yang perlu diselamatkan karena kondisinya yang sudah sangat memprihatinkan akibat adanya proses eutrofikasi dan degradasi kualitas air. Kondisi eutrofik Danau Rawapening disebabkan oleh pengkayaan unsur hara karena pasokan bahan organik secara alami maupun yang berasal dari aktivitas manusia, yang ditandai dengan tingginya konsentrasi total Nitrogen dan Posfat sehingga memacu pertumbuhan yang tidak terkontrol / blooming hydrilla. Blooming  hydrilla mengganggu fungsi Danau Rawapening sebagai pengendali banjir, perikanan dan kegiatan wisata. Namun di sisi lain bisa jadi mampu meremediasi logam berat Pb dengan cara mengakumulasi sebagai akibat dari aktivitas manusia yang meliputi pertanian, peternakan, industri pariwisata, dan industri perumahan. Sudah ada penelitian – penelitian  yang dilakukan untuk mengeksplorasi potensi hydrilla untuk remediasi, namun masih dalam skala laboratorium dengan  kondisi lingkungan yang terkontrol. Oleh karena itu perlu dilakukan penelitian mengenai potensi fitoremediasi hydrilla yang ditanam di Danau Rawapening (in - situ) untuk mengkaji bioakumulasi Pb pada hydrilla di Danau Rawapening. Penelitian  dimulai bulan Agustus – Oktober 2013 menggunakan 1 jenis tanaman yaitu hydrilla dan lama waktu tanam  3 minggu. Tanaman di tanam dengan metode mesocosm yaitu ditanam di dalam plot ukuran 1m3 dengan kepadatan tiap plot yaitu 1 individu dengan berat basah 100 gram dan diamati tiap minggu untuk dihitung kandungan  logam Pb. Parameter yang diamati adalah kandungan logam berat Pb sedimen dan akar hydrilla untuk memperoleh nilai BAF (bioaccumulation factor). Hasilnya adalah nilai bioacumulation factor (BAF) Pb sedimen paling tinggi oeh hydrilla adalah minggu kedua sebesar 97,90%. Hydrilla memiliki potensi untuk mengurangi pencemaran logam berat Pb yang terkandung di dalam sedimen dan dapat dipanen dalam waktu 2 minggu.   Kata Kunci : Eutrofikasi, Danau Rawapening, hydrilla, bioakumulasi, fitoremediasi</dc:description>

	<dc:description xml:lang="en-US">Soy tofu whey is residual water in the process of tofu manufacturing which is derived from the remaining soy milk clotting. Tofu whey contains bioactive compounds which have been studied previously could be potential as an antioxidant, antimicrobial, anti-mutagenic, and antihypertensive. This study aim was to produce pleasant JF-Soywhey and make society healthy. Manufacturing of JF-Soywhey was conducted through a whey tofu fermentation process using Kefir grains at room temperature (± 28°C) for 48 hours and subsequently processed into jelly. The results showed that the products varied with fruit juice got a favoured by the panellists. In addition, the antioxidant content of products was still quite high as the ripening effects lowered the antioxidant capacity of 13.9%. Hence it could be suggested that the kefir grain fermented tofu whey could be used as an antioxidant source alternative functional food such as JF-Soywhey.</dc:description>

	<dc:description xml:lang="en-US">Telah dilakukan penelitian tentang konversi termal campuran polietilena-tempurung kelapa menjadi hidrokarbon cair melalui proses pirolisis dan pirolisis katalitik menggunakan katalis zeolit alam. Katalis zeolit alam dibuat melalui 3 tahap yaitu: aktivasi, kalsinasi dan proses hidrotermal. Enam puluh gram campuran polietilena-tempurung kelapa dengan perbandingan 5:1, 4:2, 3:3, 2:4, 1:5 dipirolisis pada temperatur 300°C. Uap organik yang dihasilkan kemudian didinginkan sehingga diperoleh produk cair. Untuk proses pirolisis katalitik, prosedurnya sama, hanya dilakukan penambahan katalis pada reaktor. Produk cair kemudian dianalisis dengan GC dan GC-MS. Dari keseluruhan proses menunjukkan bahwa volume produk cair pirolisis dan pirolisis katalitik campuran polietilena-tempurung kelapa makin meningkat dengan meningkatnya jumlah polietilena di dalam campuran. Data GC dan GC-MS menunjukkan bahwa proses pirolisis menghasilkan produk utama berupa senyawa hidrokarbon rantai karbon C4 – C11 dan proses pirolisis katalitik menghasilkan senyawa hidrokarbon rantai karbon C8 – C12.   Keywords: pirolisis, pirolisis katalitik, hidrokarbon cair</dc:description>

Dalam  implementasinya,  terdapat  hal-hal yang tidak tepat bila direpresentasikan  hanya secara  benar  dan  salah. Karena itu, digunakanlah  sistem  logika fuzzy dimana terdapat  nilai-nilai diantara benar  dan  salah. Konsep  ini banyak diaplikasitan  terutama  untuk sistem  kontrol, salah  satunya  pada  traffic light. Sistem  pengaturan traffic light dengan konsep  logika  fuzzy mampu  bekerja  sesuai  kondisi  jalan yang diaturnya.  Sistem  inferensi  fuzzy menggunatan  metodi Min-max. Input crisp diubah menjadi input  fuzzy, kemudian  dievaluasi  dengan basis  pengetahuan  menggunakan  kaidah-kaidah  fuzzy  yang akhirnya  dihasilkan sebuah solusi daerah fuzzy. Daerah solusi ini selanjutnya dilakukan defuzzisasi untuk mendapatkan  sebuah solusi  crisp  sebagai  dasar penentuan  durasi lampu hijau pada traffic light.Kata  kunci  : Logika fuzzi, sistem inferensi fuzzy, metode  min-maxPermalink : http://ejournal.undip.ac.id/index.php/sm/article/view/3117</dc:description>

	<dc:creator>Firdausi, Ketut Sofjan</dc:creator>
	<dc:description xml:lang="en-US">In this study, the phenomena of natural polarization has been used as a preliminary test of vegetable oil quality. The formation of saturated fatty Acid (SFA) has been studied as a most responsible parameter for degradation of oil quality related to its expired limitation. The Oil quality was indicated by change of light polarization, and was measured using pair of polarizer-analyser. The result shows that the change of polarization can be used to indicate oil quality level related to its expiration date. This method also shows predicted SFA formation and apparently it is relative more powerful than standard parameters such as free fatty acid (FFA) test and peroxide value (PV) test. For future, this method has provided good prospect to evaluate the existence of the halal level of oil due to lard (pig oil). Keywords: natural polarization, vegetable oil quality, saturated fatty acid (SFA)</dc:description>

	<dc:description xml:lang="en-US">The purpose of Linear Quadratic Regulator (LQR) optimal control system is to stabilize the system, so that the output of the system towards a steady state by minimizing the performance index. LQR-invinite horizon is a special case of LQR in thecontinuous time area where the terminal time of the performance index value for infinite time and infinite outputsystem is zero. Performance index will be affected by the weighting matrix. In this paper will be discussed about the application of Particle Swarm Optimization algorithm (PSO) and Differential Evolution Algorithm (DEA) to determine the state feedback of a closed loop system and weighting matrices in the LQR to minimize performance index. PSO algorithm is a computational algorithm inspired by social behavior of flocks of birds and fishes in searching of food. While the DEA is an optimization algorithm that is adopted from evolution and genetics of organisms. Simulations of the PSO algorithm will be compared with DEA. From the simulations results is found thatDEA is faster then PSO to get convergence to the optimal solution.   Keywords: LQR-invinite horizone, Particle Swarm Optimization (PSO), Differential Evolution Algorithm (DEA), umpan balik keadaan, sistem lup tertutup </dc:description>

	<dc:description xml:lang="en-US">Simulation of Gamma spectroscopy with Bismuth Germinate Oxide (BGO) and NaI(Tl) detectors has been done using Monte Carlo method in MCNPX computer program. Simulation was conducted by modelling detector scintillator geometry, model of radiation source which was Cobalt-60 and pulse count model. BGO and NaI(Tl) had a diameter of 3 inch and thickness of 3 inch and closed by Aluminium with 0.05 cm thickness. Extended radiation source of Cobalt-60 was in radius of 0.15 cm which was put in front of detector surface with distance of 0.001 cm, 2 cm, 4 cm, and 12 cm. The simulation results showed that the less radiation count with increasing distance of the radiation source which was put in front of detector. Reduce of the radiation count lead to decrease efficiency in each increase of radiation source distance. The detector efficiency to count gamma ray radiation of BGO detectors was better than NaI(Tl) detector. The maximum efficiency of both detectors was occurred at distance of 0.001 cm in front of detector. These results also showed that MCNPX was able to agreeably simulate detector process to determine spectroscopy Gamma response.</dc:description>

	<dc:description xml:lang="en-US">Lingkungan urban merupakan habitat kompleks yang dikembangkan manusia dari lokasi alami atau lahan pertanian yang secara berangsur-angsur dan sepenuhnya telah mengubah kondisi alami menjadi kondisi tidak alami. Lingkungan urban dan sub-urban menyediakan habitat yang sesuai untuk sejumlah kecil fauna kalajengking. Kalajengking sebagai hewan pemangsa berperan dalam  menjaga keseimbangan ekosistem dan jaring makanan, namun demikian kontak dengan manusia menjadikan keberadaan kalajengking dalam lingkungan urban menjadi dilema tersendiri. Penelitian bertujuan untuk mengkaji keberadaan dan karekteristik habitat kalajengking di lingkungan urban di Jatiluhur, Jatingaleh, Semarang. Teknik pengamatan dilakukan dengan observasi secara langsung. Data pengamatan berupa karakteristik habiitat dijelaskan secara deskriptif. Hasil penelitian telah ditemukan dua spesies kalajengking yaitu Chaerilus variegatus dan Isometrus maculatus.

	<dc:description xml:lang="en-US">Kabupaten Semarang merupakan salah satu kabupaten di Jawa Tengah dengan jumlah  peternak itik petelur lokal cukup banyak. Berbagai itik lokal dibudidayakan oleh masyarakat setempat, antara lain itik Pengging, Magelang, dan Tegal. Selain letaknya yang strategis, wilayah ini memiliki kondisi mikroklimat yang menunjang kegiatan budidaya itik petelur. Mikroklimat merupakan salah satu faktor penting yang berpengaruh pada produktivitas itik petelur. Penelitian ini bertujuan menganalisis produktivitas itik petelur lokal di Kabupaten Semarang dengan menggunakan beberapa indikator penting, yang meliputi konversi pakan (KP), rasio antara pakan dengan bobot intestinum (BK:BI), dan rasio antara bobot intestinum dengan bobot badan (BI:BB). Metode yang digunakan adalah sampling sederhana dengan cara memilih ketiga jenis itik petelur lokal yang berumur 6 bulan (itik siap bertelur), antara lain itik Pengging, Magelang, dan Tegal, masing-masing sebanyak 6x ulangan. Pengukuran bobot pakan dilakukan setiap hari dengan menggunakan timbangan digital. Bobot badan diukur setiap 5 hari sekali selama satu bulan, sedangkan bobot intestinum diukur pada akhir bulan. Hasil penelitian menunjukkan bahwa itik petelur Pengging memiliki nilai KP 98,04, BK:BI = 2,17, dan BI:BB = 0,05, sedangkan itik Magelang dan Tegal, berturut-turut (134,08; 4,08; 0,03) dan (101,35; 2,57; 0,04). Kesimpulan penelitian ini adalah bahwa itik Pengging memiliki kemampuan konversi pakan, rasio bobot pakan dengan bobot intestinum, dan rasio bobot intestinum dengan bobot badan yang lebih baik dibanding itik Magelang dan Tegal. Berdasarkan indikator tersebut, itik Pengging lebih produktif dibanding itik Magelang dan Tegal dan direkomendasikan untuk dibudidayakan, terutama di daerah yang memiliki karakteristik mikroklimat seperti yang ada di  Kabupaten Semarang.   Keywords: itik petelur, produktivitas, konversi pakan, intestinum, bobot badan</dc:description>

	<dc:description xml:lang="en-US">The antioxidant growth and potency of yeast Rhodosporidium paludigenum DUCC Y-007 have been studied on two treatment mediums. The yeast could grow on two treatment mediums and the dry weight results obtained during the incubation period of 120 hours were 7.17 g/L and 7.33 g/L. The concentration of reducing sugars in stabilized medium were 3.14 g/L and 3.30 g/L at 72-120 hours incubation time respectively. There were differences in pH changes during incubation time which at YPG medium, it tended to increase whereas at semi synthetic medium, the pH tended to decline. Total carotenoid on YPG medium was 50.13 µg/g cell and on the semi-synthetic medium was 197.50 µg/g cell. Antioxidant activity measured by DPPH reagent showed the results at YPG medium was 50% and at semi-synthetic medium was 61%.</dc:description>

	<dc:description xml:lang="en-US">Studi ini bertujuan mengkaji potensi whey tahu sebagai substrat menggunakan Saccharomyces cerevisiae dan mempelajari pengaruh luas permukaan elektroda dalam menghasilkan beda potensial pada sistem MFC. Tahapan penelitian meliputi konstruksi reaktor MFC, pengukuran beda potensial pada variasi substrat yaitu membandingkan beda potensial yang dapat dihasilkan oleh substrat whey tahu dengan substrat glukosa, dan pengukuran beda potensial pada variasi luas permukaan elektroda dengan masing-masing luas permukaan elektroda grafit sebesar 13,29 cm2, 26,58 cm2, 39,87 cm2, dan 53,16 cm2. Hasil penelitian menunjukkan bahwa whey tahu memiliki potensi dengan dihasilkannya beda potensial maksimum 11,73 mV/100 ml substrat dalam sistem MFC menggunakan S. cerevisiae. Hasil studi juga menunjukkan bahwa semakin besar luas permukaan elektroda, semakin besar pula beda potensial yang dihasilkan. Hal ini dibuktikan dengan luas elektroda grafit 53,16 cm2 menghasilkan beda potensial 40,67 mV/100 mL substrat whey tahu dan 300 mV/100 mL substrat glukosa.   Kata kunci: Whey tahu, Microbial fuel cell, Saccharomyces cerevisiae, dual-chamber MFC      The preliminary research about the utilization of soy whey as a substrate and the effect of electrode surface area in microbial fuel cell (MFC) system has been conducted. Laboratory-scale experiment of MFC was carried out in order to determine the ability of soy whey to act as substrate using Saccharomyces cerevisiae and the influence of electrode surface area to generate a potential difference in MFC system. The study includes the MFC reactor design, measuring a potential difference at variation of substrate (soy whey and glucose), and evaluate a potential difference at a variation of graphite electrode surface area. The results show that soy whey has an ability to be applied as a substrate in the MFC system using S. cerevisiae with potential difference 11,73 mV/100 ml. The variation of electrode surface area in the MFC system with four graphite electrodes (53.16 cm2) give the best potential difference with 40,67 mV/100 ml of soy whey and 300 mV/100 ml of glucose substrate.   Keywords: Soy whey, Microbial fuel cell, Saccharomyces cerevisiae, dual-chamber MFC</dc:description>

	<dc:description xml:lang="en-US">The percentage of people affected by diarrheal diseases are still quite high, reaching 5.2%. Therefore we need an effort to identify the factors that cause diarrhea efforts of the government in order to reduce morbidity of diarrhea optimally. Such efforts include reviewing of the factors causing the incidence of diarrhea by focusing on linkages between regions or spatial aspects. Spatial aspect is considered important to study because between regions must have different characteristics. One approach that can be used is a spatial model Geographically Weighted Poisson Regression (GWPR) which is a local form of the Poisson Regression. This research was conducted in Semarang city with the unit of observation is the 16 districts in Semarang city. The results showed that the locally influential variable is the number of protected drinking water facilities and the number of medical personnel available. This model has a level of accuracy of 84.33%.</dc:description>

	<dc:description xml:lang="en-US">ABSTRAK---Metode Statistik yang sering digunakan dalam percobaan adalah analisis ragam. Dalam tulisan ini akan dibahas analisis ragam dengan pengaruh tetap diselesaikan dengan pendekatan metode regresi,hal itu dapat dilakukan kalau modelnya diindetifikasi secara benar dan kalau langkah-langkah pencegahan telah diambil agar diperoleh persamaan normal yang bebas. Suatu ciri analisis ragam adalah bahwa model analisis ini terparameterisasi secara berlebih (Overparameterized), sehingga perlu membuat kendala terhadap parameter-parameternya. Pendekatan model regresi terhadap masalah analisis ragam mengharuskan peubah bebas X dalam bentuk katagori, yaitu nol dan satu. Kata kunci : analisis ragam, kendala</dc:description>

	<dc:description xml:lang="en-US">BaFe12O19 is a permanent magnetic material which has superior properties to be excellent until the late of twentieth century. Some of the obstacles in the synthesis of the material using a stoichiometric composition is a difficulty to obtain a single phase and the second phase is always found. This research attempted to make modifications on the initial non-stoichiometric composition by varying the fraction of Ba/Fe through BaCO3 and Fe2O3 compound through solid state reaction mechanism. This solid state reaction was initiated by mixing various fractions of BaCO3 and Fe2O3 powder composition and compacted to produce a homogeneous mixture using a planetary milling. After drying and molding, it was obtained a homogeneous mixture like a cylinder with a diameter of 2:54 cm and a thickness of 0.5 cm. The BaFe12O19 phase was obtained by heating the sample at a temperature of 1200 ° C for 4 hours. To determine changes in the fraction of Ba/Fe before and after sintering, the samples were tested by X-Ray Fluorescence (XRF), while the structure and crystallinity were tested by X-ray diffraction (XRD) and Scanning Electron Microscope (SEM). The results showed that during the heating process, the reduction of barium fractions exceeded 5% from of their initial weight, while changes in the fraction of Fe was not significant. The results of structure and crystallinity measurement showed that the addition a substantial amount of barium carbonate can lead to the decrease of crystallinity from 35.271 nm to 11.265 nm.</dc:description>

	<dc:description xml:lang="en-US">We studied zooplankton community structure in defferent ecosystem type where different species of aquatic plants are presented. The different in zooplankton community structure can be attributed to different aquatic plant species. We used two different species of aquatic plants, Sargassum plagyophyllum and Gracilaria verrucosa in shrimp pond ecosystem. Every aquatic plant species were replicated three times, and three enclosures without aquatic plant were used as controls. The different in morphological complexity of aquatic plant may affect zooplankton community structure. Our results indicated that the presence of aquatic plant differ in affecting zooplankton community structure. In general, pond with aquatic plant indicate more abundant and diverse of zooplankton. In the presence of Sargassum zooplankton was more abundant compared to the presence of Gracilaria. Whereas with Gracilaria, zooplankton biodiversity index were higher than with Sargassum.   Keywords: zooplankton, sargassum plagyophyllum, Gracilaria verrucosa.</dc:description>

	<dc:description xml:lang="en-US">An evaluation of the value of the slice thickness due to changes in tube voltage and tube current on the CT scan have been performed. The evaluation is done by making images using CT performance test phantom. Testing is done by performing three scanning on each slice. Exposure factors used were 120 kVp-60 mA, 160 mA 120-kVp, 140-kVp 60 mA, and 140 kVp 160 mA. Nominal beam width were 2 mm, 3 mm, 5 mm, 7 mm, and 10 mm. Once the axial image was obtained (on the area for slice thickness determination),  then calculated the average CT number on the region of interest (ROI). After it was made graphs to determine the value of FWHM which indicates the magnitude of the thickness of the slice. From the test results obtained that changes in tube voltage and tube current does not affect the value of the thickness of the slice. Also found that the value of slice thickness for each thickness, greater than the nominal beam width.   Keywords: Phantom CT Performance Test, Slice Thickness, CT-Scan         Telah dilakukan evaluasi terhadap nilai slice thickness terhadap perubahan tegangan tabung dan arus tabung pada pesawat CT scan. Pengujian dilakukan dengan membuat citra menggunakan fantom CT performance test. Pengujian dilakukan dengan melakukan eksposi sebanyak tiga kali pada tiap-tiap slice. Faktor eksposi yang digunakan yaitu 120 kVp-60 mA, 120 kVp-160 mA, 140 kVp-60 mA, dan 140 kVp-160 mA. Slice thickness yang diuji adalah ketebalan 2 mm, 3 mm, 5 mm, 7 mm, dan 10 mm. Setelah didapatkan citra aksial pada bagian daerah uji slice thickness, maka diambil beberapa lokasi ROI dan dihitung rerata CT Number, kemudian nilai tersebut dibuat grafik dan ditentukan nilai FWHM yang menunjukkan besarnya slice thickness. Dari hasil pengujian diketahui perubahan tegangan tabung dan arus tabung tidak berpengaruh terhadap nilai slice thickness. Hasil pengukuran diketahui bahwa nilai slice thickness untuk masing-masing ketebalan, lebih besar dibanding nominal beam width.

	<dc:description xml:lang="en-US">The curve of 2D isodose is used to determine the dose distribution in patient treated by radiotherapy. Therefore, isodose curve is very useful for planning and evaluating of the dose received by the patient. Correction of 2D isodose curve for sloping surface is very important due to the skin of patient is not flat. In this study, the correction of isodose curve was calculated using tissue air ratio (TAR) method for radiation field size of 10x10 cm2. The correction factor was obtained by comparison of TAR value for effective depth and TAR value for total depth. The correction factor then was multiplied to isodose curve for flat surface. In this study, the software for calculating the automated correction factor due to sloping of patient surface has been successfully developed. It was found that if the sloping of patient surface increases then the corrected isodose curve increases. Key wods: 2D isodose curve, tissue air ratio (TAR), correction factor, sloping patient surface.</dc:description>

	<dc:description xml:lang="en-US">FTIR spectroscopy combined with canonical variate analysis was used for differentiation of java tea (Orthosiphon stamineus) according to their geographical origin. FTIR spectra of all java tea samples were acquired in the mid infrared region (wavenumber range 4000-400 cm-1). Preprocessing signal of FTIR spectra has been carried out prior to canonical variate analysis by standard normal variate. Combination of FTIR spectra in the region 1800-900 cm-1with canonical variate analysis has the power to differentiate java tea samples in terms of geographical origin. The developed method could be used for identification of geographical origin of java tea based on the samples used in this study.</dc:description>

	<dc:description xml:lang="en-US">The active fraction of methanol-HCl extract of Roselle flower (Hibiscus sabdariffa. L) has been identified and its inhibitor xanthine oxidase potential tested. The aim of this study was to compare the inhibitory activity of xanthine oxidase from methanol-HCl extract and its fractionation results and to identify the chemical component of Roselle flower’s methanol-water active fraction which had xanthine oxidase inhibition activity. The chemical component identification of Roselle flower was preceded by extraction and fractionation. The types of chemical compound contents were identified by the spotting appearance, UV-Vis and IR spectroscopy. The quantification of chemical compound was carried out by TLC Scanner and xanthine oxidase inhibitory activity was tested in vitro. From this research, it was obtained the methanol-HCl extract yield of 4%. The Roselle methanol-HCl extract has the ability to inhibit activity of xanthine oxidase (IC50) was 0.64 ppm which was preponderant than the fractionation result. The 2nd fraction was the most active to inhibit the xanthine oxidase activity compared to the 1st and 3rd fraction. The main components of 2nd fraction were isolates A (Rf 0.9) and isolates D (Rf=0.64) which were expected as the group of anthocyanin. The relative level of isolate A and D were 4.67% and 24.24% respectively.</dc:description>

	<dc:description xml:lang="en-US">ABSTRAK---Penelitian ini dilakukan untuk menguji hipotesis bahwa rimpang temu putih mempunyai aktivitas sebagai antibakteri dan menentukan KHTM (Konsentrasi Hambat Tumbuh Minimum). Rimpang temu putih diambil filtratnya kemudian dibagi tiga. Pertama langsung diuji aktivitasnya, kedua diotoklaf kemudian diuji aktivitasnya dan ketiga dikeringkan (bubuk). Ketiga filtrat tersebut diuji terhadap pertumbuhan bakteri E.coli dengan metode kertas cakram. Aktivitas antibakteri filtrat rimpang temu putih tanpa otoklaf lebih tinggi dibanding yang diotoklaf. KHTM bakteri E.coli adalah 10 mg/mL dengan konsentrasi yang menghasilkan hambatan maksimum pada 50 mg/mL sebesar 6,83 mm. Filtrat rimpang temu putih dapat dipakai sebagai antibiotik terhadap penyakit yang disebabkan oleh E.coli.   Kata kunci: antibakteri, temu putih, Konsentrasi Hambat Tumbuh Minimum (KHTM)</dc:description>

	<dc:description xml:lang="en-US">Coronary heart disease (CHD) is a health problem and is one of the leading causes of the death in both developed and developing countries. Thereby it needs to analyze the factors which influence it. Some factors supposedly influence the CHD’s patients are cholesterol levels, low density lipoprotein levels, high density lipoprotein levels, triglyceride levels, systolic blood pressure, diastolic blood pressure and gender. The data used are secondary data from the medical records of CHD’s patients and general check-up records of the healthy people in a hospital in Yogyakarta. The analysis used in this research is binary logistic regression response with dichotomous dependent variables. Of the seven suspected factors, only four significant influence factors namely cholesterol levels, high-density lipoprotein levels, systolic blood pressure and diastolic blood pressure.   Keywords: CHD, logistic regression</dc:description>

	<dc:description xml:lang="en-US">ABSTRACT---Eutrofikasi adalah pengkayaan perairan oleh unsur hara, khususnya nitrogen dan fosfor sehingga mengakibatkan pertumbuhan tidak terkontrol dari tumbuhan air. Berdasarkan kandungan unsur haranya, maka perairan dapat dikategorikan menjadi oligotrofik, mesotrofik dan eutrofik. Danau Rawapening menerima inlet dari 16 sungai dan hanya memiliki 1 outlet, menyebabkan akumulasi materi yang cukup tinggi. Penelitian ini bertujuan untuk mengkaji status trofik Danau Rawapening, sehingga dapat menjadi landasan dalam upaya pengembangan pengelolaannya. Pengambilan sampel air dilakukan pada Februari 2008 pada 7 titik untuk analisis fitoplankton dan kandungan total nitrogen, fosfor, silikon, potasium, kalsium dan mangaan. Pengukuran temperatur, DO, pH, kekeruhan, konduktivitas, turbiditas dilakukan secara in-situ. Pengambilan sampel air untuk analisis BOD dilakukan menggunakan 2 botol gelap 300mL, botol pertama diukur DO0, botol ke-2 diinkubasi selama 5 hari kemudian dihitung DO5.. Penghitungan kandungan klorofil menggunakan metode spektrofotometri. Berdasarkan kandungan klorofilnya, maka dapat dihitung nilai produktivitas primer. Berdasarkan kandungan Total Fosfor Danau Rawa Pening dalam kondisi mesotropik, tapi berdasarkan kandungan Total Nitrogen dankecerahan perairan yang kurang dari 2 meter termasuk dalam kondisi eutrofik. Hal ini ditunjukkan oleh dominannya Aulacoseira granulata dan Melosira varians. Kualitas air seperti pH, DO, kecerahan, kandungan logam berat mengalami degradasi dan cenderung melebihi ambang batas Baku Mutu Lingkungan. Ekoteknologi merupakan pendekatan yang dapat diimplementasikan di Danau Rawapening, menjadikan eceng gondok sebagai sabuk hijau, dan pembuatan preimpoundment di hilir inlet sebelum masuk ke danau.Key words: status trofik, eutrofikasi, danau Rawapening, pengelolaan danau</dc:description>

Generator of ions was a positive corona discharge plasma with multi point to plane electrodes configurations and by using  a DC voltage source of 6.8 kV and 8 mA. In the glow discharge plasma condition, the  nitrogen ions were produced in air. Implantation of nitrogen ions can increase the levels of nitrogen in the compost. The highest percentage of nitrogen is obtained in the series of experiment for time of radiation was 100 minutes. The amount  of mass percentage of nitrogen in the enrichment  compost was  (3.4 ± 0.3) % and  we compare with compost control without ions radiation was 1.1 % (mass percentage). It can be concluded that the increasing of nitrogen content in the compost can be done by almost 300 % .   Key words : corona glow discharge plasma, compost, nitrogen ionic</dc:description>

	<dc:description xml:lang="en-US">In this study, the phenomena of natural polarization and electrooptics effect have been compared as alternative methods for evaluation of vegetable oil quality. The sample used in the experiment was various vegetable oils. The change of light polarization was measured using a pair of polarizer for natural polarization and in case of electrooptics with addition of induced external electric field through DC high voltage. The result has shown that both methods are able to indicate the level of various oil quality. The natural polarization is very useful for preliminary test of oil quality. In the other hand, the electrooptics has a good prospect as single physical indicator for vegetable oil quality.</dc:description>

	<dc:description xml:lang="en-US">ABSTRACT---Diazepam, formalin and drink which contain alcohol are substances that can be a toxic if they are accumulated  in a body. Drink  that contains alcohol can make someone drunk. Diazepam  is a medicine that calms and  its  function  is  to decrease neuron activity. While  formalin which  is  to used as  food preservation causes metabolism disorder. This aim of this research was to investigate and analyze the physiological aspect of M musculus body after it was treated with diazepam, formalin and drink alcoholic. The research used completely Randomize Design. The animal  that was  in experiment were 16 male M musculus and divided  into 4  treatments and 4 replications. The treatments were P0 (Control), P1 (0.04 mg Diazepam), P2 (100 ppm Formalin), P3 (Drink which contains 4,8% alcohol ). Food and drinking water were ad libitum. The treatments were given daily for 30 days. The data were analyzed with anova. The result  indicated that were not significant for all parameters. So, it was concluded  that 0.04 mg diazepam, 100 ppm  formalin and drink which contains 4,8% alcohol didn’t change the metabolism of M musculus body.  Key words: diazepam, formalin and drink alcoholic</dc:description>

	<dc:description xml:lang="en-US">Diatom is a unicellular micro algae that had an important role in the food web and major contributor of oxygen in the water. The short life cycle, rapid reproduction, cosmopolite, wide spread distribution, variation in population, most are sensitive to the environmental changes, easily handle samples and identification, low cost of  sampling and data analysis may promote diatoms as a powerful bioindicator of water quality. The unique siliceous frustules make diatoms able to preserve in the sediment. Rawa Pening is a semi natural lake that administratively surrounded by four districts that consist of 27 villages. The main problem of this lake is erosion in the upstream and sedimentation in the downstream area as well as uncontrolled of aquatic plant growth, particularly water hyacinth (Eichornia crassipes) that induce lake shallowness. For people who live around Rawa Pening, this lake had been used for agricultural irrigation, fisheries, electricity power and tourism. To conserve the lake, as 3rd World Water Forum in Tokyo, March 2003 and 2006 – 2009 National Research Agenda there is a need of limnological research on the environmental changes. This research was conducted in order to study the potential used of epipelic diatom as bioindicator of lenthic ecosystem, particularly Rawa Pening Lake. Water and sediment samples were taken from 27 sites from inlet, outlet and water body of Rawa Pining Lake. There were 254 diatom species that consist of 8 Centrophycidae species and 246 Pennatophycidae species. The population varied between 6,989 and 3,781,000 individual/gram. Based on diversity indices of diatom, some part of Rawapening Lake was unstable, whereas the others were stable based on the diversity indices. Based on epipelic diatom, Rawa Pening Lake and its catchments area might be divided into 3 groups: agricultural lotic ecosystem, settlement lotic ecosystem and lenthic ecosystem. The high population of Synedra ulna, Nitzschia palea  and Aulacoseira  indicated that the lake is eutrophic that tent to be hypereutrophic. It was supported by high concentration of total nitrogen and phosphorous. The concentration of heavy metals Cadmium, Chromium, Copper and Lead were very high in sediment. However, the government of Indonesia has not yet set up sediment quality criteria. The following research would be proposed on this matter.   Key words: diatom, bioindicator, water quality, Rawapening </dc:description>

	<dc:description xml:lang="en-US">Komposit CNT/PVA telah dibuat dengan metode solution processing. Polyvinyl alcohol (PVA) dilarutkan dalam akuades bertemperatur 80°C, dan kemudian carbon nanotubes (CNT) ditambahkan ke dalam larutan tersebut dengan berbagai variasi rasio fraksi massa CNT/PVA sebesar 10, 20 dan 30%. Komposit CNT/PVA terbentuk setelah dikeringkan dalam oven bertemperatur 90°C. Sifat mekanik komposit CNT/PVA dikarakterisasi dengan uji tarik. Komposit CNT/PVA yang memberikan sifat mekanik terbaik selanjutnya digunakan sebagai acuan dalam pembuatan komposit dengan variasi ketebalan. Komposit dengan variasi ketebalan dibuat dengan 3 metode yaitu cetak tebal, cetak lapis tebal dan cetak lapis tipis. Analisis dari uji tarik menunjukkan bahwa komposit CNT/PVA dengan fraksi massa 20% CNT/PVA  menghasilkan modulus Young yang paling besar yaitu 137,710348 MPa. Metode cetak lapis tipis menunjukkan peningkatan yang lebih besar dibandingkan dengan metode cetak tebal, dan cetak lapis tebal. Komposit dengan 3 lapis dan ketebalan 0,94 mm menghasilkan modulus Young sebesar 212,825166 MPa dan peningkatan  modulus Young komposit CNT/PVA terhadap modulus Young dari PVA sampai 107,30%.</dc:description>

	<dc:creator>Tarno, Tarno</dc:creator>
	<dc:description xml:lang="en-US">ABSTRAK---Model regresi linier merupakan model yang paling sering digunakan dalam analisis statistika. Model regresi linier ini digunakan untuk menyatakan hubungan fungsional antara satu atau beberapa variabel bebas (prediktor) terhadap satu variabel terikat (respon). Dalam analisis regresi, mengestimasi parameter secara otomatis mengestimasi model regresi. Untuk memperoleh estimasi model regresi dapat dilakukan dengan beberapa metode antara lain: metode kuadrat terkecil, metode maksimum likelihood dan sebagainya. Salah satu metode yang paling populer adalah metode kuadrat terkecil (OLS). Pada prinsipnya metode kuadrat terkecil mengestimasi model regresi dengan meminimalkan rata-rata kuadrat sesatan (MSE). Dalam tulisan ini dibahas suatu metode alternatif untuk mendapatkan estimasi model regresi yaitu metode median kuadrat terkecil (LMS). Pada metode LMS, estimasi model yang diperoleh adalah suatu model yang memiliki median kuadrat sesatan terkecil. Prosedur estimasinya adalah dengan memilih p titik sampel (dengan p: banyaknya parameter di dalam model termasuk intersept) dari n titik sampel hasil pengamatan, kemudian ditentukan suatu persamaan yang melalui p titik tersebut. Setelah diperoleh sejumlah persamaan yang melalui p titik tersebut, kemudian ditentukan median dari residual kuadrat. Persamaan atau model yang diestimasi melalui p titik yang menghasilkan nilai median kuadrat terkecil merupakan model yang terpilih.   Kata Kunci: regresi linier, estimasi parameter, sesatan kuadrat</dc:description>

	<dc:description xml:lang="en-US">The mammography use the specific x-ray energy. At high x-ray energies (&gt;35 keV) the subject contrast between the normal and malignant tissues in the breast is poor, at very low x-ray energies (10-15 keV) the contrast is highest, however the high absorption result in a high tissue dose. To achieve to good result must be used the optimal energy, that could be achieved by using specific x-ray target and additional filter materials to generate characteristic x-ray of the desired energy. This research was aimed to evaluate the influence of target-additional filter combination and filter thickness to the x-ray energy spectrum. The research was conducted by Monte Carlo simulation using EGSnrc program. The model of mammography tube was designed by BEAMnrc program, and phase space file was resulted by BEAMnrc was analyzed by BEAMDP. The tube x-ray contained of target and additional filter from molybdenum (Mo) and rhodium (Rh) material, window from berrylium, and collimator from Pb. Target-additional filter combination were Mo-Mo, Mo-Rh, Rh-Rh and Rh-Mo.  Variation of additional filter thickness that be used are 0,001 mm; 0,03 mm; and 0,05 mm. The results of the simulation indicated that an x-ray consist of bremmstrahlung and characteristic. X-ray spectrum were produced by Mo target had characteristic x-ray energy 17 keV and 19 keV, and Rh target had characteristic energy 20 keV and 23 keV. Target-additional filter combination that allowed are Mo-Mo, Mo-Rh, and Rh-Rh combination. Rh-Mo combination could not be used, because Mo filter would attenuated x-ray characteristic energy. For the Mo-Mo and Rh-Rh, the thicker the additional filter then the x-ray spectrum obtained has a more narrow, but the reduced intensity of the x-ray bremmstrahlung and characteristic.   Keywords: target-filter combination, x-ray spectrum, mammography, EGSnrc.</dc:description>

	<dc:description xml:lang="en-US">Deteksi fragmen Open Reading Frame (ORF)100 dan ORF29 telah dilakukan pada dua jenis padi gogo rancah beras merah yaitu varietas Slegreng dan Mandel. Metode penelitian dilakukan dengan cara isolasi DNA kloroplas padi diikuti dengan amplifikasi PCR menggunakan optimasi suhu annealing pada tiga suhu yang berbeda, yaitu 53°C, 55°C, dan 56°C. Selanjutnya hasil amplifikasi divisualisasikan menggunakan elektroforesis pada gel agarose 1%. Suhu annealing 53°C merupakan suhu yang optimal untuk memperlihatkan fragmen ORF100 dan ORF29. Hasil penelitian menunjukkan bahwa fragmen ORF100 dan ORF29 dapat teramplifikasi pada padi Slegreng dan mandel, sehingga kedua jenis padi tersebut menunjukkan kecenderungan subspesies japonica. Perbedaan ketebalan dan ukuran pita tidak mempengaruhi keberadaan fragmen ORF100 dan ORF29 sebagai penanda untuk mengidentifikasi tipe indica atau japonica. Pemanfaatan marka molekuler fragmen ORF100 dan ORF29 dalam mendeteksi jenis padi diharapkan dapat melengkapi hasil karakterisasi dan pengelompokkan varietas padi berdasar karakter morfologi dan fisiologi.   Keywords: chloroplast DNA, ORF100, ORF29, indica-japonica differentiation </dc:description>

	<dc:description xml:lang="en-US">ABSTRACT---We  investigate  the  effect  of  quixalud  on  food  preference  and  resistance  from degradation.  Quixalud  was  choosen  because  of  its antimicrobial  properties  but it  is not an antibiotic.  The aim of this research  is to  evaluate  the effect of  quixalud addition on food preference  by tiger shrimp and its resistant from degradation.  The experiment  was designed  using Factorial with  two treatments:  quixalud concentration  and soaking  period.  We used  three  concentration  of quixalud:  30 ppm 60 ppm and  90 ppm.  Each  concentration  were soaked  at  difference  period  of time, which were:24  hours,  48 hours  and  72 hours.  Food  preference  and  resistance from  degradation were monitored. Results indicated that  there was no  different  of  shrimp  food  preference between  quixalud feed and controls or  feed without quixalud.  However,  there was a tendency  that shrimp preferred  feed  with 60 ppm of quixalud.  Quixalud  has  no effect  on  the  remaining  solid  feed. It seem  likely that the remaining solid feed  is mainly affected by the strength  of binder rather  than  the presence  of an antibacterial compound,  such  as  quixalud.Keywords  : quixalud, food preference, resistance, degradation.Permalink : http://ejournal.undip.ac.id/index.php/sm/article/view/3114</dc:description>

	<dc:creator>Purwantisari, Susiana</dc:creator>
	<dc:creator>Evendi, Agus</dc:creator>
	<dc:description xml:lang="en-US">Fusarium moniliforme and Alternaria solani are two types of mold which often cause the diseases of cultivated plants. Fusarium moniliforme causes the ear rot disease on corn and the wilt disease of Solanaceae family. Whereas the pathogenic fungus Alternaria solani causes an early bright disease on the onion and potato. This aim of this study was to determine the ability of fungal antagonist Trichoderma viride in inhibiting the growth of Fusarium moniliforme and Alternaria solani in vitro. The growth inhibition ability test were conducted on dual cultures by growing the fungal antagonists with pathogenic fungi in Petri dish containing potato dextrose agar media face-to-face in a distance of 3 cm. Percentages of the growth inhibiting were observed every day in 7 days incubation. The results showed that the fungal antagonist T. viride exhibited the highest inhibition on F. moniliforme in 3 days incubation period which was 63.07 %. Yet the highest inhibition against A. solani was in 2 days incubation period which was 57.35 %. T. viride growth continued to increase since the first day until the seventh day incubation period but contrarily the growth of both pathogenic fungi underwent inhibition. This suggested that T. viride was potential as a biological control agent of F. moniliforme and A. solani growth and have a potency as an active bio fungicide ingredient.

	<dc:creator>Bahtiar, Nurdin</dc:creator>
	<dc:description xml:lang="en-US">In the implementation of curriculum 2013 at high school level, the majoring for students was started from the level of class 10. The available major options are Math and Natural Sciences (MIA), Social Sciences (IIS), and Linguistics and Cultures (IBB). The process of determining the major was conducted by the counseling teacher through a careful selection based on several criteria including grades, graduation test scores, record of accomplishment, student's selected major, and psychological test results. During the process of determining the major, the school often has to deal with several constraints associated with the standard acceptance rules from each major department. To deal with these constraints and minimize the occurrence of human errors, it needs a Decision Support System to carry out the process. In this study, the system is made to apply the Profile Matching method. Profile Matching method calculated the competence of each individual based on given criteria. The implementation of Profile Matching method is optimized by placing core and secondary factor dynamically on each majoring department in order to obtain an ideal results from the majoring selection process. In order to provide added value to the system, an SMS Gateway feature has been installed to help broadcasting the majoring selection results to the participating students.</dc:description>

	<dc:description xml:lang="en-US">Disturbance of water environment due to organic enrichment caused by farming activities may result in the reduction of water quality and sediments. This study was conducted to determine the condition of the water and sediments in the area of aquaculture in ponds system compared to the adjacent coastal area of industrial activities. Water qualities observed were the temperature, DO, salinity, conductivity, turbidity and pH. Sediment characteristics measured were sediment grain size and organic matter content contained in the sediments. From the research, the temperature values obtained ranged 28.7-32.9°C, DO 3.63 to 6.4 mg/l, pH 4.31 to 6.27, salinity 4.6 to 33 ‰, conductivity 8.5- 50.2 ms/cm, turbidity 73-535 NTU. The substrate grain analysis showed at the fish farm area in pond systems was dominated by silt 71.70% and clay 16.71%. In the coastal area adjacent to the industrial activities, 93.38% substrate was dominated by sand. Analysis of organic matter content in the pond systems exhibited the highest ranged between 0.72% -1.16% for nitrogen and 3.20%-10.35% for carbon. The differences in the composition of the substrate and the organic material can be caused by hydrographic conditions, especially strong/weak water currents, the accumulation of litter originating from the decomposition of leaves of mangrove, enrichment of nutrients during the decomposition of litter and aquaculture activities and industries.</dc:description>

	<dc:description xml:lang="en-US">Makrobenthic animals are invertebrates that relatively small (at least 500 µ ) and have short life spans, and play an important role as secondary producers in the structure of the food chain in the water ecosystem. They inhabit substrates/sediment at the bottom of the water column, either at the surface (epifauna) or in the sediment (infauna). Therefore, it needs proper method of collecting these animals. The procedures that need to be considered when collecting samples of macrofauna marine animals are sampling techniques, the type and size of the sampling tool , mesh size , and methods of preservation and fixation . In carrying out a study to determine the level of environmental disturbance aquatic ecosystems , in addition to disturbed areas , we need to use the control or reference areas for comparison . This area is ideally a region relatively undisturbed by human activity or environmental disturbance is assumed not to occur. Areas that are ecologically potentially disturbed areas can be cultivated fish / shrimp ponds in coastal systems , aquaculture floating net cage systems in a river or lake, disposal area (outlet) of industrial waste , etc. . While the reference area/control can be in the coastal mangrove areas , water areas without any human activities, and upstream river that are at least 1 km away from the disturbed area.</dc:description>

	<dc:description xml:lang="en-US">Abstrak ---Julang emas  merupakan  salah  satu  jenis burung Bucerotidae  yang  seluruh  jenisnya  saat ini  terancam  punah  karena  jumlah populasinya  yang terus menurun. Salah  satu hal yang menyebabkan penurunan  tersebut  adalah  berkurangnya kawasan  habitat  yang  menyediakan  vegetasi  sebagai  sumber  pakan, tempat berlindung, bermain,  istirahat, mengasuh  dan membesarkan  anak-anaknya.  Gunung Ungaran menrpakan  salah  satu  habitat  buruag  Julang  emas  yamg  terdapat  di Jawa  Tengah.  Prevalensi  Julang  emas  di Gunung  Ungaran  hanya  terdapat  di Bukit Watuondo  dan  Bukit Gentong.  Tujuan  penelitian  ini adalah  untuk membandingkan  struktur  dan komposisi vegetasi antara Bukit  Watuondo dan Bukit  Gentong, serta mengetahui  ketersediaan  vegetasi  yang  berpotensi  sebagai  habitat  sarang  dan  sumber  pakan  di kedua  wilayah tersebut.  Bukit Watuondo  dan  Bukit Gentong  ditentukan  sebagai  stasiun  pengamatan.  Masing-masing  stasiun dibagi menjadi 5 titik  sampling.  Setiap  titik  sampling  dibuat satu  fransek  yang  terdiri atas  5 plot ulangan berukuran  10x10 m dan ditentukan  secara sistematik.  Analisis data menggunakan  Indeks Nilai  Penting,Indeks  Kemelimpahan  dan  Indeks  Keanekaragaman.  Hasil penelitian  menunjukkan  terdapat  90  jenis pohon yang  tergabung  dalam  37  famili. Bukit Watuondo  memiliki  indeks  keanekaragaman  jenis yang  lebih  rendah dibandingkan  Bukit Gentong.  Bukit Watuondo  lebih berpotensi  sebagai  habitat  sarang  dibandingkan  denganBukit Gentong.  Ketersediaan  Ficus  yang  lebih banyak  di Bukit  Gentong  merupakan  habitat  sumber pakan bagi Julang emas.  Melihat data vegetasi  yang diperoleh, perlu dilakukan penanaman  pohon Ficus agar populasi  Julang  emas  di Gunung  Ungaran  tidak mengalami  penurunan  dan  akhirnya  punah.Kata kunci: vegetasi,  habitat,  Julang  emas  (Aceros  undulatus),  Gunung  Ungaranpermalink : http://ejournal.undip.ac.id/index.php/sm/article/view/2961</dc:description>

	<dc:description xml:lang="en-US">ABSTRACT-The non-linear optical property of rotary power of light polarization in water has been develop using the Radio-Freguency field (RF-Field). The RF-Field used in the experiment is produced by RF generator, and it supplies the frequency in the range betwen 6,04 to 14,56 MHz which then applies to the samples. The source of light with 632,8 nm-wavelength and 532 nm-wavelength are used to observe the change of range polarization of the light after it passes througt the samples.  Three modes of the direction of the electric field of light are chosen 0o (E//) (E of light is parallel to E of RF-Field), and 90o (E ) (E of light is perpendicular to E of the RF-Field) in order to determinate the optimal change of the angle of the polarization β. The values of β is measured as a function of RF-Field,  , where ωRF is the angular frequency of RF-Field and  BRF is the magnitude of magnetic field measured in the center of the coil which is assumed to be homogeny in the circumstances of the samples. The results of the experiment show that the degrees of change of the polarization direction, η is largest at the E3 mode. It shows also that at small wavelength of light we obtain the larger η, which is indicated the higher frequency of liglt will more induce the dipoles of molecules of the samples.

	<dc:description xml:lang="en-US">Aloe vera is known containing compounds which have potencies as antioxidants, such as group of anthraquinones (especially emodin and aloin), flavonoids, tannins, saponins, and sterols. In this research, comparison of total phenolics content, antioxidant activity and cytotoxicity of the methanolic extract and its fractions had been conducted. The Aloe vera extract was fractionated using a solvent gradient system to obtain fractions of n-hexane, dichloromethane, ethyl acetate and water. The analysis of total phenolic and activity were performed on extracts or fractions that showed a positive result to the phenolic test. Total phenolic content was determined by the Folin - Ciocalteu method, determination of antioxidant activity was by DPPH radical reduction and determination of cytotoxicity was by BSLT (Brine Shrimp Lethality Test). The results showed that the yield of methanol extract, fractions n-hexane, fraction of dichloromethane, ethyl acetate and water fraction were 0.580% ; 0.006% ; 0.093% ; 0.0092% and 0.410% respectively. Methanolic extract, ethyl acetate fraction and the water fraction showed positive result on phenolic test. Total phenolic compounds from water fractions was (16. mg gallic acid equivalent/g extract or fraction) which had greater level than Emet and Fea (12.47 and 0.89). Fraction of water had the highest antioxidant activity (IC50 433 mg/L) compared to Emet (IC50 519.23 mg/L) and Fea (IC50 1311.36 mg/L). All of three samples had cytotoxic potency, water fraction (Fair) was the most active sample (LC50 5.209 ppm) compared to Emet (LC50 18.383 ppm) and Fea (LC50 56.486 ppm). Overall it can be proposed that the water fraction is the most active fraction compared to the other fractions or extracts.</dc:description>

	<dc:description xml:lang="en-US">ABSTRACT---An experiment to obtain high productivity of baby corn’s cob by casting treatment has been conducted. The aims of this experiment were to study the casting effect for baby corn productivity and to obtain the efficient dose of casting to increase baby corn productivity. This experiment was done by a Randomized Complete Design with four treatment and seven replication. The treatments were four kinds of casting dose, i.e 0g/plant, 200g/plant, 400g/plant and 600g/plant in their growth media. The measurable parameter were fresh weights, dry weights and cob quantity of baby corn. The casting was analyzed qualitatively including C/N ratio and organic material of casting. The result showed that the casting can increase the cob of baby corn productivity eventhough the efficient doses of casting to increase the baby corn productivity were not obtained.   Keywords: baby corn, casting, cob</dc:description>

	<dc:description xml:lang="en-US">Jerami merupakan bahan lignoselulosa, terdiri atas lignin yang terikat pada hemiselulosa dan selulosa. Sebagian besar penelitian biodegradasi biomassa secara mikrobiologis, memanfaatkan kerja mikroba tunggal yang umumnya bekerja kurang optimal. Dalam penelitian ini jerami didegradasi menjadi gula pereduksi menggunakan konsorsium mikroba dari kompos termofilik. Fermentasi jerami padi dilakukan pada media semisolid menggunakan starter kompos termofilik, dan proses degradasi dipantau berdasarkan kadar gula pereduksi yang dihasilkan setiap 24 jam. Kelimpahan mikroba diamati melalui fragmen gen 16S dan 18S rRNA dengan teknik SSCP (Single Strand Conformation Polymorphism). Degradasi optimum jerami padi didapatkan pada jam ke-72 dengan kadar gula sebesar 0,474 mg/L. Profil pita-pita SSCP ditunjukkan dengan perbedaan jumlah dan intensitas pita-pita dari kelompok jamur maupun bakteri. Perbedaan pita-pita tersebut menunjukkan adanya perbedaan kelimpahan komunitas mikroba baik pada konsorsium kompos maupu mikroba pendegradasi jerami padi.   Keywords: biodegradasi, kompos termofilik, komunitas mikroba, SSCP  </dc:description>

	<dc:creator>Soeprobowati, Tri Retnaningsih</dc:creator>
	<dc:description xml:lang="en-US">Secara spasial, diatom tersebar hampir di semua ekosistem perairan, bahkan di tempat lembab dan basah. Dinding sel diatom tersusun dari silika, sehingga fosil diatom dapat tersimpan dengan baik dalam sedimen. Penelitian ini dilakukan untuk mengkaji variabilitas keanekaragaman diatom Danau Rawa Pening secara vertikal. Perbedaan keanekaragaman dan kemelimpahan diatom pada perlapisan sedimen mengindikasikan perbedaan lingkungan saat diatom tersebut diendapkan. Sampel sedimen diambil dari 2 lokasi di Danau Rawa Pening, dengan representasi inlet dan tengah danau. Pengambilan sampel dilakukan dengan hand auger. Sampel sedimen dalam corer kemudian diiris tiap 0,5 cm. Diatom dipisahkan dari sedimen dengan perlakukan HCl dan H2O2. Identifikasi diatom dilakukan dengan mikroskup perbesaran 1.000 kali hingga dijumpai minimal 300 valva. Selanjutnya dilakukan penghitungan kemelimpahan relatif dan indeks keanekaragaman Shannon-Wiener. Secara vertikal, keanekaragaman diatom variatif antara 1,49 – 3,49. Rendahnya indeks keanekaragaman berkaitan dengan dominansi spesies. Diatom centrales mendominasi lapisan permukaan dengan populasi relatif tinggi dengan spesies dominan Aulacoseira ambigua, A. distans dan A. granulata. Genus Eunotia mendominasi pada lapisan tengah dan Nitzschia palea dan Synedra ulna mendominasi lapisan dalam. Berdasarkan perbedaan kemelimpahan spesies tersebut mengindikasikan  perbedaan kandungan total fosfor dan pH pada saat diatom tersebut diendapkan. Rekonstruksi masa lampau Danau Rawa Pening perlu dilakukan untuk memastikan adanya perubahan kualitas perairannya.   Keywords: diatom, keanekaragaman, Rawa Pening, distribusi vertikal, kualitas perairan</dc:description>
