Judul: Analisis Risiko Produksi Pada Usaha Peternakan Ayam Broiler Bermitra dan Mandiri di Kabupaten Serang Propinsi Banten
Abstrak: One of the many farms which has the potential national meat contribution is broiler chickens farm. Serang Regency is one of the broiler production centers in Banten, and it encourages the emergence of partner companies. PT.Berkah Mitra Sejahtera is a company which forms a partnership with three broiler poultrymen in Serang District. There are few independent broiler chicken farms there. The aim of the study was to identify the sources of the farm production risks of the independent or contract farming, to analyze the likelihood of the risks and impacts of farm production risk sources,to compared risks production broiler chicken farm of independent or contract farming, to analyze and to analyze alternative strategies to handle the farm producton risk sources. There were four farm production risk resources found in the contract farming farms i.e, diseases whose average probability was 39.43 percent, weather changes - 31.93 percent, poorer DOC quality - 24.23 percent, and predators - 12.90 percent. Similiarly there were also four farm production risk resources found in the independent poultryman’s farm, i.e diseases whose probability of which was 50.00 percent, weather changes - 46.40 percent, predators - 23.30 percent, and poorer DOC quality - 18.10 percent.Based on t-test showed the risk production being largest for contract farming because p-value >α=0.05,so that no reject Ho. Risk mapping results indicate that there were two strategies, namely preventive and mitigation strategies. Diseases were a source of risk that had the highest possibility and the greatest impact.

Abstrak: One commodity that many farms are cultivated by breeders of broiler chickens. Broiler breeding process has a shorter culture period than other farm commodities. Broiler chicken farming is inseparable from the existence of business risks. The most common risk is the risk of production and price risk. On-farm production of plasma risk is one risk is quite high, while the independent farm price risk is the risk that a major effect on earnings. This study aims to analyze the sources of risk that affecting farmer’s income, the effect of production risk and price risk to the farmer’s, analyzing the influence of a partnership, as well analyzing alternative strategies appropriate to address existing risks. The method used is a risk analysis, revenue analysis and analysis of the revenue balance (R/C Ratio). The comparison of income between farmers and the plasma independent of Rp 58 618 500 and the value of R/C Ratio of the received independent farmers is 1.16. while in this period plasma farmers suffered losses of Rp -4 465 900 and R/C Ratio of 0.73

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.
