Judul: Sumber-Sumber Risiko Produksi Usahaternak Ayam Broiler Pada Peternakan Mitra Dramaga Unggas Farm (DUF)
Abstrak: Broiler farms is one of the businesses that has the potential for national poultry supply. Bogor District is one of broiler production central in West Java.So grow the companypartners on broiler farm such as Dramaga Unggas Farm (DUF). The mortality indicated the presence of production risk in partner farmers Dramaga Unggas Farm. The purpose of this research are to analyze thesources of production risk, analyze the probability of risk sources, analyze the impact of risk sources and alternative strategic for handling it. Identification of production risk in broiler farm use descriptive analysis resulted such as risk of weather, predators, cage density, layout cage, post-vaccination, dry feet (dehydrated), and disease. This research using Probability analysis with Z-score method and Implication Analysis with VaR method. The results mapping risk indicate that there two kinds of management strategies such as preventive and mitigation strategies. The disease was the source of risk that had the highest probability and the worst impact. The farmers should do strategy by prioritizing strategy that caused by a source of risk of disease.

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: 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.
