Judul: Anal isis Risiko Diversifikasi Sayuran Organik Pada The Pinewood Organic Farm di Bogor, Jawa Barat
Abstrak: Vegetables as one of the parts of the horticulture and have a business opportunity if managed properly. Vegetables is one of the organic agricultural products of environmental friendly nature and get closer to nature concept, so as to provide a good quality assurance compared to conventional vegetables. Besides having the advantages of environmentally friendly farming organic vegetables have a pretty big obstacle is the high level of risk, including the risk of production. The purpose of this study was to analyze the activities of specialization and develop alternative strategies commodity diversification by presenting the right combination to reduce the magnitude of the risk of farming in the specialization of activities. Meanwhile, the risk measure used include opportunities, expected return, variance, standard deviation, and coefficient of variation. The results of the analysis indicate that the specialization of activities Broccoli is a commodity with the lowest coefficient of variation is equal to 0.17. The combination of Broccoli and Carrots are the most diversified activities lower risk than other commodity combinations

Judul: Analisis Risiko Produksi Sayuran Organik pada KebonKu Farm di Kabupaten Bogor Provinsi Jawa Barat
Abstrak: KebonKu Farm merupakan perusahaan yang bergerak dibidang agribisnis, khususnya budidaya sayuran organik. Dalam melakukan usaha budidaya organik KebonKu Farm menghadapi masalah produksi yang menyebabkan tingkat produktivitas sayuran organik yang diusahakan berfluktuasi yang mengindikasikan bahwa KebonKu Farm mengalami risiko dalam usahanya. Tujuan penelitian ini adalah mengidentifikasi sumber-sumber risiko yang dihadapai KebonKu Farm, menganalisis risiko produksi dalam pengelolaan sayuran organik pada kegiatan spesialisasi dan diversifikasi, dan menganalisis alternative strategi yang dapat dilakukan KebonKu Farm untuk menangani risiko usahanya. Berdasarkan hasil analisis risiko pada kegiatan spesialisasi diperoleh risiko yang paling tinggi terdapat pada sayuran bayam jepang sedangkan yang paling rendah terdapat pada sayuran wortel. Hasil analisis risiko diversifikasi menghasilkan kombinasi paccoy dan bayam jepang merupakan diversifikasi yang paling tinggi risikonya sedangkan risiko yang paling rendah adalah wortel dengan paccoy.

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.
