Judul: Analisis Risiko Produksi Benih Ikan Patin Siam (Pangasius hyphotalamus) pada Faholo Farm Kecamatan Ciseeng, Kabupaten Bogor.
Abstrak: Komoditas ikan patin siam dikembangkan dalam bentuk usaha pembenihan oleh Faholo Farm. Faholo Farm dalam kegiatannya menghadapi risiko produksi yang ditunjukkan dengan adanya fluktuasi mortalitas rate (MR). Usaha pembenihan Faholo Farm ditemukan risiko karena mengingat benih ikan patin siam yang dipelihara masih dalam keadaan yang kecil, serta masih rentan kematian. Tujuan penelitian ini adalah mengidentifikasi sumber-sumber risiko produksi, menganalisis probabilitas dan dampak risiko, dan alternatif strategi penanganan risiko. Data yang diperoleh dianalisis menggunakan analisis deskriptif, analisis z-score, dan analisis Value at Risk (VaR). Hasil penelitian menunjukkan bahwa risiko produksi pembenihan ikan patin siam di Faholo Farm adalah faktor musim, kanibalisme, kualitas air, perubahan suhu air, penyakit, kerusakan peralatan teknis, dan keterampilan tenaga kerja. Nilai probabilitas, dampak risiko, dan status risiko dari sumber risiko produksi pada Faholo Farm diperoleh nilai yang tertinggi dan menjadi prioritas utama adalah kanibalisme. Usulan alternatif strategi yang dibuat pada penelitian ini diharapkan dapat membantu masalah risiko produksi yang dihadapi oleh Faholo Farm.

Judul: Analisis Sumber Sumber Risiko Produksi Pembenihan Ikan Patin Siam pada Pasir Gaok Fish Farm di Kabupaten Bogor
Abstrak: Siam’s catfish is potential commodity which can develop in Indonesia. This commodity has been developed by Pasir Gaok Fish Farm (PGFF). PGFF faces the production risk as indicated by the production fluctuation and enhancement of catfish seed mortality. The purpose of this study are to identify the sources of production risk, analyze the probability, impact of risks, and alternative strategies. The data was analyzed with descriptive analysis, z-score analysis, and analysis of Value at Risk (VaR). The results showed that prodution risks of siam’s catfish in PGFF are cannibalism, diseases, water quality, and human error. Probability value of each highest risk source consist of cannibalism, diseases, water quality, and human error. The impact of the each highest production risk arerisk of disease, cannibalism, water quality, and human error. Based on the probability and impact of risk, prevention strategies needed to be implemented to solve the risk of cannibalism and disease with giving fresh natural food according to the needs of fish and right time.

Judul: Elektrodeposisi Film Tipis Semikonduktor Cu2ZnSnS4 (CZTS) pada Substrat Kaca ITO
Abstrak: Semiconductor Cu2ZnSnS4 (CZTS) thin film that can be used as absorber layers on solar cell module was made via electrodeposition method. CZTS thin film was electrodeposited on the surface of a silicate glass coated with a thin layer of indium tin oxide (ITO). Deposition process was done using potentiostatic mode at room temperature with a potential of 1.05 V for 30, 45, and 60 minutes, followed with annealing the film at 2 different temperatures, 500 ºC using furnace and 180 ºC using hot plate, both treatments for 45 minutes in N2/H2S atmosphere. The X-ray difractograms were analyzed using Match 2 program and showed that the CZTS thin films had kesterit crystalline structure, with a low percentage of CZTS phase. The thin film also contained secondary phases such as Cu2S, ZnS, and SnS. The obtained CZTS thin films had a thickness between 1.039 and 1.676 μm. Absorption study showed that the band gap energy of CZTS thin films which was annealed using furnace ranged from 1.50 to 1.52 eV, whereas that annealed using the hot plate was not observed. The band gap energy value showed that CZTS thin films can be used as sunlight absorber layers on solar cell. The formation of CZTS crystal film on this investigation was effectively performed using furnace annealing process at a temperature of 500 ºC with deposition time of 45 minutes.
