Judul: Risiko Produksi Ayam Ras Pedaging Pada Peternakan di Kecamatan Pamijahan Kabupaten Bogor, Jawa Barat
Abstrak: Husbandry is one of the agricultural sector which has a potential to be developed. One of the many husbandry commodities grown in Indonesia, especially in West Java is broiler. Similarly with other agribusiness, broiler husbandry also has risk especially production risk which seen from the chicken mortality at each production period. This research objectives are to indentify production risk sources, to analyze the sources’s probability and impacts, and to determine alternative strategy due to reduce the risk probability and impacts. To reach the research objectives, this research use several method such as Z-score and Value at Risk (VaR). Production risk sources at broiler husbandry in Kecamatan Pamijahan are weather, pests and predators, disease, and environmental disorders. According to probability the source which has the biggest probability is pests and predators and the lowest probability is environmental disorders. The biggest impact caused by disease and the lowest impact caused by environmental disorders.

Judul: Analisis Risiko Produksi pada Peternakan Ayam Broiler di Kampung Kandang, Desa Tegal, Kecamatan Kemang, Kabupaten Bogor, Jawa Barat.
Abstrak: Poultry is an important sub sector in contributing to GDP. One of poultry commodities which has big potential is broiler farm. Bogor District is one of broiler production central in West Java with growth rate about 7.75%. Meanwhile, broiler production in Bogor District is fluctuation. The purpose of this research is to analyze the risk of production sources, analyze the probability of risk source, and analyze the impact of risk sources in Kampung Kandang. Risk analysis broiler production was examined using primary data and secondary data. Primary data obtained through observation, interviews, discussions, and questionnaires with the farmers, while the secondary data obtained from the relevant literature. Method of data analysis on this research use descriptive analysis of the data using qualitative and quantitative risk analysis using the data. The sources of risk found broiler production is a weather, disease, and predators. Disease are a source of risk that may occur and the greatest impact, amounting to 91.62 percent and Rp 7 857 249. The results of mapping risk indicate that there are two kinds of management strategies such as preventive and mitigation strategies. In conducting a proposed strategy, the farmers should do strategy by prioritizing strategy that is caused by a source of risk of disease

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.
