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.

Abstrak: Broiler farming is one of the potential business because there is still a gap between demand and supply. In addition, this business has a rapid turnover of capital. However, this business is high risk and requires substantial capital. One of the strategy that is used to overcome the problem is a partnership. Cogreg Village is one of the broiler producing areas in Bogor District. Most of the broiler farming in Cogreg are small and conventional farm. That is managed by a partnership like, which the partnership is different from broiler partnership in general. The objectives of this study are to analyze the partnership and to compare the farm performance between partnership and independent broiler farm in Cogreg Village, Parung Subdistrict, Bogor Regency. Broiler business partnerships in the Cogreg Village uses sharing system. The results showed that production, income, and the R/ C ratio of farmer partners are higher than independent farmers on each scale. This proves that the partnership has a positive effect on production and income broiler farming. However, based on a qualitative analysis can be said that the benefits sharing is not balanced. The benefits that received by company is much higher than the farmer’s.

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.
