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: 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: Characterizations of low alloy steel sae 4422  plated with chromic acid (Cro3)
Abstrak: Characterizations of low alloy steel SAE 4422 plated with chromic acid (CrOrO3) was use Optical Microscopy (OM), Scanning Electron Microscopy (SEM), X-Ray Diffraction (XRD), RD),Energy Dispersive Analysis of X-Ray (EDAX), Hardness Test and Roughness Test. Microstructures analysis exhibits cracks and grain boundaries microcracks as a characteristics of chrome metal found at plating metal. Perlite and Ferrite as grains of steel found at base metal with grain boundaries around it. Phase analysis of plating metal appropriate to chrome metal with lattice constant (a) is 2.559 Å and phase analysis of base metal appropriate to iron ferrite with lattice constant (a) is 3.318 Å. Both plating and base metal have cubic system. Chemical analysis of plating metal at surface section exhibits that cracks area have highest value of carbon element compare with grains and grains boundaries area. While chemical analysis of base metal at cross section exhibits that perlite have highest value of carbon element compare with ferrite and grain boundaries. The hardness value of plating metal at surface section and cross section are 753 and 637 VHN. While, the hardness value of base metal and interface area at cross section are 205 and 373 VHN. The roughness value at measurement points of chrome surface for as received sample are 0.445 μm. Observation used Optical Microscopy and Scanning Electron Microscopy exhibits surface irregularities combine to form surface texture of plating metal at surface section.
