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: Peran Kemitraan dalam Mengendalikan Risiko Produksi Usahaternak Domba di Kabupaten Bogor.
Abstrak: Bogor berada di wilayah yang sangat strategis untuk menjangkau pasar domba Jabodetabek. Usahaternak domba di Kabupaten Bogor sangat potensial untuk dikembangkan tetapi dihadapkan dengan banyak risiko terutama risiko produksi. Para pelaku usaha menjalankan kerja sama pola kemitraan untuk meminimalisir risiko. Tujuan penelitian ini untuk menganalisis pengaruh faktor produksi, menganalisis tingkat risiko, dan menganalisis peran kemitraan. Pengambilan responden menggunakan metode purposive dengan jumlah masingmasing peternak mitra dan non mitra adalah 30 responden. Penelitian ini menggunakan analisis model Just dan Pope, analisis tingkat risiko, dan analisis pendapatan. Hasil penelitian ini menunjukkan bahwa variabel yang berpengaruh nyata terhadap produktivitas domba adalah bakalan, pakan hijauan, pakan konsentrat, pakan lain-lain dan dummy kemitraan, sedangkan pada risiko produksi adalah bakalan, pakan konsentrat, tenaga kerja dan dummy kemitraan. Analisis tingkat risiko menunjukkan bahwa risiko yang dihadapi peternak mitra lebih kecil. Kemitraan memiliki peran yang signifikan menurunkan risiko produksi usahaternak domba.

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.
