Journal Title: Scholars Academic Journal of Biosciences - Year 2015, Vol 3, Issue 2
Abstract
Abstract: Mangrove becomes main ecosystem that the more important supporting life in coastal regions. Subang regency is one of areas in West Java that still has mangrove region. The result of data analysis LANDSAT-TM Multitemporal that show in the period 1988-1992 had happened mangrove areas reduction (of 2.087,7 ha to be 958,2 ha) that caused by activities of land conversion including the expansion of fishpond areas, while the addition of board (to 3.074,3 ha) in the period 1992-1995 that show the successes of social forestry which was conducted through tumpang sari fishpond/wanamina/silvofishery.The utilization of mangrove for wanamina in the regency of Subang is currently undergoing rapid development so that required assessment of the sustainability of resources and against efforts have been done in wanamina. One of tools used to evaluate the sustainability of mangrove management with wanamina system is Rapid Appraisal for Fisheries (RAPFISH) that is a method of assessment of the sustainability of fisheries based on multidimensional scaling. The objectives this study were (a) to calculate the level of business feasibility with wanamina system, and (b) to determine the status of sustainability of mangrove management with wanamina system in coastal Blanakan, Subang. The study was conducted in coastal Langensari village Blanakan district Subang Regency, Province of West Java for three months in October until December 2014. Wanamina activities conducted in coastal Langensari has a level feasibility is quite effective and efficient. The economic analysis of four parameters under consideration entirely show a positive contribution to sustainability of wanamina, i.e. (a) there are a large number of species that is utilizing of mangrove, (b) existence of interaction biofisik, (c) across the result of cultivation of fish/shrimp and non cultivation of mangrove large enough, and (4) low input from the activities of wanamina.The results of ordinasi RAPFISH impact on all dimensions of sustainability, whether the ecology dimension, economic dimension, social dimension and multidimension entirely show “enough sustained status” with the value of the index was at >50-75 hose value. This condition can reflect that mangrove management with wanamina system in coastal Blanakan, Subang regency be in state of being sufficient optimal. Based on analysis of Leverage in the method RAPFISH there are seven sensitive indicators contributed to the sustainability index, i.e. (a) water quality, (b) density of mangrove, (c) market of fishpond yields, (d) job types, (e) the status of land ownership of fishponds, (f) work pattern, and (g) the level of public education. Keywords: Coastal Blanakan, RAPFISH, Sustainability index, Wanamina.
