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: Pembuatan Film Tipis Cu2ZnSnS4 sebagai Lapisan Penyerap Cahaya pada Sel Surya Menggunakan Metode Elektrodeposisi
Abstrak: Thin film of Cu2ZnSnS4 (CZTS) is an alternative semiconductor used as light absorber layer on solar cell. CZTS can replace silicon that commonly used as commercial semiconductor. The advantage of using CZTS as absorber layer is due to the abundance of its chemical composer on earth, and its high value of absorption coefficient. The absorber layer was made by using electrodeposition method on ITO glass substrates. The films were deposited at room temperature using potentiostatic mode with a potential of –1.05 V for 30, 45, and 60 minutes. After that, the films were annealed at two different temperatures, 180 ºC and 500 °C, for 45 minutes in N2/H2S atmosphere. Based on X-ray diffraction analysis, the polycrystalline thin film obtained fall into kesterite crystal phase. This type of crystal was obtained when the CZTS was annealed at 500 °C in H2S/N2 atmosphere. The value of optical band gap energy for the CZTS thin film was 2.2 eV with the film thickness about 1.228–6.366 μm. The sample of CZTS with electrodeposition time of 45 minutes and annealing temperature of 500 °C showed the best result and in conformity with absorber layers criteria for solar cells.
