SUSTAINABILITY STRATEGY OF MARINE CULTURE BUSINESS IN KEPULAUAN SERIBU

Abstract

Marine culture business is an alternative profession that has a positive impact on Kepulauan Seribu society. One of the commodities being developed is hybrid grouper Epinephelus sp. Further research needs to be carried out to determine whether the running business is optimal and feasible to function. Cobb-Douglas model be used to determine optimization production, Stochastic Frontier Analysis model to estimate the risk of variable inputs uses, and investment analysis to determine business feasibility. The results showed that the marine culture business in Kepulauan Seribu was in a condition of increasing return to scale (RTS = 1.489) so that the variable input of livestock and rearing period needed to be increased and net cage (KJA) and labor needed to be reduced so that production was an optimal. The variable inputs of livestock, rearing period, and labor are risk decreasing while the KJA variable is risk increasing. The feasibility analysis is divided into three clusters with positive investment values, namely cluster 1 (Panggang and Kelapa Dua sub-district) NPV Rp. 9,101,233,927, IRR 122%, Net B/C 3.9, PP 3.2 years; cluster 2 (Tidung and Pari sub-district) NPV Rp 2,937,199,206, IRR 127%, Net B/C 4, PP 3 years; and cluster 3 (Lancang sub-district) NPV Rp. 2,189,009,750, IRR 107%, Net B/C 3.4, PP 3.7. Resulting alternative strategies using blue ocean strategy is to reduce the use of net cage, eliminate non-hybrid livestock grouper input, raise hybrid livestock grouper and investors, and create a market integration of live hybrid grouper in Kepulauan Seribu.
