Judul: Analisis Risiko Diversifikasi Sayuran Indigenous (Kasus: Usahatani Anggota Kelompok Tani Mitra Tani Parahyangan, Kabupaten Cianjur)
Abstrak: Indigenous vegetable is a vegetable local which one of Indonesia's biodiversity. Farmer groups in agribusiness, particularly vegetables in Cianjur one of which is the Mitra Tani Parahyangan Farmers Group. Productivity fluctuations indicates a risk in farming. The purpose of this research is to analyze the activity of specialization and diversification undertaken by the farmer members Group Mitra Tani Parahyangan by looking at the extent of the risks faced by and devise an alternative strategy of diversification by providing the right combination of commodities to reduce the risk of farming on the specialization activities carried out by farmers Group members Mitra Tani Tani Parahyangan. A methods of collecting data done by means observation, interviews, discussions and filled out the questionnaire to 25 respondents. Respondents were selected consisting of 10 tomato farmers, 10 cabbage farmers, and 5 leunca farmers. The process of sampling respondents conducted by purposive sampling method . Data processing was performed using Microsoft Excel 2007. While the measure of risk used cover opportunities, expected return, variance, standard deviation, and coefficient of variation. Sources of risk faced by farmers Farmers Group members of Mitra Tani Parahyangan is precipitation, fog, and pests and diseases. Results of the analysis indicate that the specialization of activities leunca is a commodity with the lowest coefficient of variation is equal to 0.27. The combination of these two commodities namely leunca and cabbage is the most diversified activities namely lower risk of 0.29 compared to a combination of two other commodities as well as the tomatoes and tomato and cabbage leunca. Alternative strategies that can be run by farmers group members of Mitra Tani Parahyangan to decrease the risk of production is the timing and the right commodity diversification activities and the control of pests and diseases .

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: Electrophoretic Coating of Apatite Compouds on Stainless Steel 316L.
Abstrak: Stainless steel (SS) 316L is a metal which is used to bone plate. However, this metal still has low biocompatibility in a human body. The metal is coated by HAp in order to increase its biocompatibility. HAp on SS 316L is coated by electrophoretic deposition (EPD) method. We used two variables in EPD process, such as voltage and coating time to obtain the best coating. The XRD difractogram showed that SS 316L has been coated by HAp. Physical observation used by microscope optics showed that the best coating is achieved on 120V during 2 minutes.
