Judul: Analisis Risiko Produksi Pembenihan Ikan Nila GMT (Genetically Male Tilapia) pada Anggota Kelompok Tani Bunisari di Desa Caringin Wetan Kecamatan Caringin Kabupaten Sukabumi
Abstrak: One type of aquaculture is the farming of tilapia hatchery GMT (Genetically Male Tilapia) in Sukabumi. Tilapia hatchery operations GMT cultivated by the farmer group members Bunisari. But in business there are members of farmer iii group Bunisari production risk constraints, seen from fluctuations Mortality Rate (MR) tilapia. The process of identifying the sources of the operations of tilapia fish GMT which is run by members of farmer group Bunisari, using descriptive analysis and then identify the likelihood and impact of risks resulting from risk sources use the Z-Score and Value at Risk (VaR). The purpose of this study was 1) to identify and analyze the sources of risk in the production of tilapia hatchery GMT on members of farmer group Bunisari in the Caringin Wetan village Caringin Sukabumi District, 2) to measure and analyze the probability and impact of risk sources on the production of tilapia hatchery GMT in members of farmer group Bunisari in the Caringin Wetan village Caringin Sukabumi district, and 3) to analyze the various alternative strategies that can be applied to address production risks faced by the business activities of tilapia fish GMT on members of farmer group Bunisari in the Caringin Wetan village Caringin Sukabumi District. Risk sources of tilapia hatchery operations GMT on farmer group members Bunisari is weather, worker skills, pests, and diseases. Probability or likelihood analysis results is greatest risk factor followed by the weather and worker skills, pests and diseases. The analysis of the impact of the greatest sources of risk are followed by disease and weather, pests and worker skills. Risk management strategy that is done for a source of risk pets, disease and expertise of farmers using prevention strategies and the risks posed by weather sources use prevention and mitigation strategies.

Judul: Analisis Pendapatan Usaha Pembenihan dan Pendederan Ikan Nila GMT
Abstrak: The research aimed to identify and analyze the structure of cost, income and business efficiency of GMT tilapia hatchery Buni Sari farm group in Caringin Wetan village, Sukabumi District with the emphasis in the segmentation of business. There are five group with different segmentation of business. Retrieval respondents method used was the method of survey. Results of the research showed cash expenditure was greater than the non-cash expenses. The largest cost component was labor, while the group with smallest production costs was Group C. Based on the income and efficiency of business comparison, the group that attempted more than one stages of hatchery activities showed the trend to get profitability and efficiency of business higher than the group that attempted only one stages of hatchery activity.
