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: Kesinambungan Usaha Bisnis Kemitraan Ayam Ras Pedaging (Kasus di Tuans Mekar Farm Bogor)
Abstrak: Usaha peternakan ayam ras pedaging merupakan salah satu alternatif usaha yang cepat menghasilkan dan waktu pemeliharaan yang singkat. Hal ini merupakan daya tarik bagi peternak untuk terjun dalam usaha ternak ayam ras pedaging. Bagi para peternak ayam, usaha ayam ras pedaging masih memiliki beberapa kendala, diantaranya kurangnya stabilisasi penyediaan DOC dan pakan dalam negeri yang murah serta berkualitas masih jauh dari yang diharapkan sehingga harganya fluktuatif. Padahal 50- 70 persen biaya produksi ayam ras adalah pakan. Kendala lainnya yaitu kurangnya modal dan sulitnya peternak untuk memasarkan produk ayamnya. Oleh karena itu terciptalah sistem kemitraan yang bertujuan untuk membantu peternak kecil mengurangi resiko kerugian yang dapat membuat pendapatannya meningkat dengan cara meningkatkan skala usahanya, menurunkan biaya produksi dan kontinuitas tersedianya sapronak, menjamin pemasarannya serta menjaga kesinambungan usahanya. Tujuan dari penelitian ini adalah untuk menganalisis hubungan peubah-peubah yang diteliti antara lain: (1) etika bisnis, (2) kepemimpinan, (3) motivasi kerjasama, (4) Performance Numerical, dan (5) kontrak kerjasama dengan kesinambungan hubungan usaha kemitraan yang sedang berlangsung.

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.
