Analisis Pendapatan dan Efisiensi Produksi Usahatani Budidaya Pembesaran Ikan Mas dan Nila Pada Keramba Jaring Apung Ganda (Studi Kasus Waduk Cirata Desa Bobojong Kecamatan Mande Kabupaten Cianjur)

Abstract

Cirata reservoir is one of three reservoirs in Citarum River that has major contribution to the fisheries in West Java. Fisheries in Cirata is conducted by fish rearing (Keramba cage) double KJA. Aquaculture of KJA performed by enlargement Cyprinus carpio and tilapia. This is because those commodities were major commodities in Cirata especially Cyprinus carpio. Enlargement of Cyprinus carpio and tilapia Aquaculture was cultivated widely in Bobojong village. The Objective of this research were to identify the structure of costs and farm income from KJA enlargement of Cyprinus carpio and tilapia aquaculturein Bobojong village by using π=TR-TC method, to analyze the factors that affect farm income from enlargement of Cyprinus carpio and tilapia aquaculture in Bobojong Village by using multiple linear regressi on analysis, to analyze the efficiency of production by using MR = MC and revenue efficiency y R/C method. Based on there gressi on results obtained, the factors that affect farmers' income significantly on the 5% through significance level were the number of Cyprinus carpio production, total production of tilapia, Cyprinus carpio seed costs, the price of tilapia seed, and the price of Cyprinus carpio feed education were not affected largely for the farm income. The results obtained on the third objectives howed that production off arming aquaculture on KJA fisheries was not optimal so that the production and production inputs used need to be optimized in order to get maximum profit. Enlargement of Cyprinus carpio aquaculture and tilapia in Bobojong Village was feasible to performed because the value of R/C off farm income from cash costs and total cost was greater than one.
