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: Pembuatan Film Tipis Cu2ZnSnS4 sebagai Lapisan Penyerap Cahaya pada Sel Surya Menggunakan Metode Elektrodeposisi
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.
