Judul: Kesinambungan usaha bisnis kemitraan ayam ras pedaging kasus di Tunas Mekar Farm Bogor
Abstrak: Contract farming has been in existence for many years as a means of organizing the commercial agricultural production of both large scale and small scale farmers. Contract farming can be defined as an agreement between farmers and marketing firms form the production and supply of agricultural product under forward agreements, frequently at predetermined prices. The objective of this research is to know relation between the analized factors wich are (1) business ethics (2) leadership (3) partnership motivation (4) performance numerical (5) contract agreements, and the sustainable contract farming. Primary data were collected by interviewing the farmers and analized using multiple regression. The result of the estimates equation of sustainable contract farming is Y= -1,740+2,939X1+1,817X4–0,911X5. Only business ethics and performance numerical were significant at the 95% level. The condition of the contract farming at Tunas Mekar Farm will be sustainable if the performance of business ethics and performance numerical improved significantly. It means that both side involved in the broiler business contract should make the best efforts to maintain it.

Judul: Peranan Kemitraan Pada Usaha Ternak Ayam Ras Pedaging
Abstrak: Usaha ayam ras pedaging merupakan salah satu usaha yang potensial dan dapat diusahakan peternak dengan skala yang bervariasi. Usaha ini umumnya dikelola secara kemitraan karena berisiko tinggi dan membutuhkan modal besar. Tujuan penelitian ini yaitu mendeskripsikan pelaksanaan kemitraan ayam ras pedaging dan menganalisis peranan pelaksanaan kemitraan terhadap keuntungan usaha peternak mitra pada dua skala usaha yang berbeda. Responden penelitian sebanyak 30 peternak bermitra yang terdiri dari 19 peternak skala kecil (≤ 5 000 ekor ayam) dan 11 peternak mitra skala besar (> 5 000 ekor ayam). Hasil penelitian menunjukkan bahwa dalam pelaksanaan kemitraan, kedudukan perusahaan inti lebih tinggi dari peternak mitra sehingga peternak tidak memiliki kekuatan tawar terhadap perusahaan. Selain itu, dalam pelaksanaan kemitraan juga masih terdapat kondisi yang dapat merugikan peternak mitra. Meskipun demikian, kemitraan berperan dalam menyediakan sarana produksi, melakukan pembinaan dalam pemeliharaan, dan jaminan pemasaran hasil. Hasil penelitian juga menunjukkan bahwa keuntungan, produksi, dan rasio R/C peternak mitra skala usaha besar lebih tinggi dibandingkan dengan peternak mitra skala usaha kecil.

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.
