Judul: Analisis Pelaksanaan Kemitraan Ayam Broiler pada CV. Barokah dan Pendapatan antara Peternak Mitra dan Peternak Mandiri di Kabupaten Bogor
Abstrak: Independent broiler farmers in Bogor District are generally characterized by small scale and face capital constraints, simple cultivation technology, less resource management, price and production risks. These constraints and limitations in broiler business will give an impact on farmers’ income. High risk of broiler raising leads to the needs of knowledge in minimizing the risk. One effort to minimize the risk of broiler business is partnership program. This study aims to (1) describe the implementation of partnership run by CV. Barokah with partner farmers, (2) analyze the characteristics of independent and partner farmers, and (3) analyze the income of partner and independent farmers. Farm management analysis was conducted using primary and secondary data. The results showed that the partnerships could provide benefits to farmers by providing production inputs, technical guidance on broiler raising and buying the products. Characteristics of partner and independent farmers were not much different. These characteristics include age, gender, education, and experience of broiler raising. Income analysis showed that partner farmers’ income was greater than independent farmers’ income. Thus, the partnership can provide benefits to farmers in increasing income.

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.

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.
