Abstract

This study aims to find strategies and methods of handling degradation of mangroves and coastal erosion in Brebes Regency. The research was conducted during the four months, June-September 2012. The results showed that community in particular mangrove Rhizophora sp and followed by Avicenia dominated mangrove ecosystem at some point on the coast along the Brebes Regency. Brebes coastal erosion occurs at different levels. Efforts to reduce coastal erosion has been done both by the public and relevant agencies through the planting of mangroves on the coast, embankment ponds, waterways and farms with breakwaters. Weighted level of public perception in the management of mangrove / coastal erosion in Brebes 92.53% (excellent), while 77.07% participation (good). Perception of the value of the correlation coefficient 0.0852 participation and closeness relation is very small, only 0.73% (do not affect each other). Ecological physical factors (X1) and socio-cultural factors (X2) jointly influence the occurrence of damage to mangroves and coastal erosion (Y), but tend to be more dominant ecological factors followed the pattern of Y = 5.042 + 0.446 X1 - 0.008 X2. SWOT analysis results show the value of total internal strategic factors 2.30 and 2.15 are in a position external segment 5 (mangrove area is relatively stable condition and possible can be developed). Analysis of the results hierarchy process (AHP) shows that the order of priority strategies / methods of managing mangrove / coastal erosion in Brebes Regency are: 1) improving protection mangrove / shore of sea waves / abrasion and develop through retention / breakwater is more effective, 2) increase empowering potential of mangrove areas through productive activities that increase the added value for improving the welfare of local communities while preserving the mangrove / coastal resources; 3) effective implementation of regulations and optimize the role of relevant institutions, civil society organizations, and the participation of local communities in conserving the mangrove areas and existing coastal resources and develop; 4) strengthen the institutional system, both government and public institutions in the management of mangrove areas for short, medium and long, and 5) increase outreach activities / community, including youth empowerment related to the importance of the existence of mangrove conservation coastal resources.
