Judul: Pengaruh Kemitraan Dalam Upaya Mengelola Risiko Produksi Usaha Ternak Domba. (Studi Kasus: Peternak Domba Mitra MT Farm (Mitra Tani Farm) Desa Bojong Jengkol, Kecamatan Ciampea, Kabupaten Bogor,Jawa Barat)
Abstrak: Sheep farming is one of the agribusinesses that is done by many farmers. Sheep farms are often found in society that is still traditional and it is not managed well. Some constraints that are faced by farmers is production risk. One of many alternatives to manage risk is partnership. This study aimed to determine the influences of partnership in managing the risk of sheep production. Analysis was performed by comparing the level of risk of sheep farming between farmers that are partnered and farmers that are not. Based on observations, the influence of partnership in managing risk is more visible on the assessment of the level of risk of pests and diseases faced by the farmers. The partnered farmers faced lesser risk compared to non-partner farmers. The coefficient of variation results obtained by the partnered farmers were smaller by 0.20 compared to non-partnered farmers by 0.26. value of R/C ratio of cash cost partnered farmers by 1.85 and 1.72 for non-partners. While the value of R/C ratio on total cost of 0.94 was the partnered farmers and non-partners of 0.59. Result of this study indicated that the partnership could reduce the risk level of production and increased of farmers income.

Judul: Pendapatan Usaha Penggemukan Domba Jantan (Kasus: Kemitraan Mitra Tani Farm dengan Peternak di Desa Bojong Jengkol, Ciampea, Bogor)
Abstrak: Desa Bojong Jengkol merupakan salah satu wilayah di Kecamatan Ciampea, Kabupaten Bogor dimana penduduknya banyak mengusahakan penggemukan domba jantan. Namun untuk mengembangkan usahanya, para peternak memiliki permasalahan seperti permodalan, manajemen, dan pemasaran. Salah satu solusi untuk mengatasi permasalahan tersebut yaitu melalui kemitraan dengan Mitra Tani Farm. Namun tidak semua peternak domba melakukan kemitraan dengan Mitra Tani Farm. Tujuan dari penelitian ini yaitu untuk mengkaji pelaksanaan kemitraan dan mengidentifikasi keragaan usaha ternak menggunakan analisis deskriptif. Selain itu untuk menganalisis pendapatan dan nilai R/C rasio usaha penggemukan domba jantan antara peternak mitra dengan peternak nonmitra. Hasil perhitungan pendapatan atas biaya tunai per SDD per periode dan nilai R/C rasio yang paling besar diperoleh peternak nonmitra Skala III. Sementara itu perhitungan pendapatan atas biaya total per SDD per periode menghasilkan nilai negatif dan nilai R/C rasio kurang dari satu untuk semua skala sehingga usaha ternak domba merugikan. Namun jika dibandingkan maka usaha pada peternak mitra Skala I yang lebih baik dibandingkan skala lainnya karena kerugian yang diperoleh paling kecil dan nilai R/C rasio nya yang paling besar.

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.
