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: Diversifikasi sayuran organik sebagai alternatif mengatasi risiko usaha pada The Pinewood Organic Farm di Kabupaten Bogor
Abstrak: Risk is the possibility of adversity or loss, and refers to uncertainty that matters. Consequently, risk management involves choosing among alternative to reduce the effect of risk. One of indicator to know the existence of production risk is the fluctuation in productivity of brokoli, tomato, bayam hijau, and carrot. This study analyzes the risk of commodity production in the four selected in the Pinewood Organic Farm with a diversified approach to analyze the risk of production of more than one commodity. Fluctuations in production will lead to revenues received also fluctuates, will be calculated risks and confectionary risk through the implementation of risk management strategies. Risk analysis is a comprehensive step in the risk assessment process. This assessment begins with the calculation of odds, the value of expected return, until the value of the risk. The analysis tools is the variance (the variance), standard deviation (standard deviation), and the coefficient of variation (coefficient of variation). Measures of deviation is also aided by another measure, namely the calculation of the odds and expected return. The results of the risk analysis calculations show that the specialization of business spinach organic green vegetables have the highest risk level of the four commodities. Based on the comparison of the risk on the four organic vegetables broccoli, tomatoes, green spinach, and carrots are done Pinewood Organic Farm concluded that diversification can reduce risk. However, by diversifying no means eliminate the risk or create a risk to zero. Diversified production activities in the Pinewood Organic Farm has been effectively implemented by the company in an effort to deal with the risk. The strategy needs to be done by the company is to improve the management of the company, to cooperate or partner with other farmers and suppliers of organic vegetables.

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.
