Abstract

During the time, sand exploitation along the coast boundary of Merauke District is carried out for supplying more than 90% on the development demand of infra-structure, resident, building, and office in Merauke Regency. It causes the damage of coast ecosystem mainly the mangrove habitat which one of the functions ia for natural shield from sea wave. However, population in Merauke District reaches 95,410 persons (44.78%) of the whole population in Merauke Regency which is in the coastal area. This condition is very dangerous to the healthy, safety, and population safety in this area from the danger threat by enironmental damage due to the illegal sand excavation. This study intends to evaluate the multi dimension impact of sand mining to the coastal environment and mangrove ecosystem. The methodology consists of the selection of location by purposie sampling approach; technique of data collecting by in depth interview; technique of analysis by descriptive analysis, multi criteria analysis, and bayes method. Results show that there has been happened the very high mangrove ecosystem damage such as more than 1,200 ha; due to the sea water intrusion, more than 1,000 metres coastal lib has threatened fresh water supply for the population demand of Mearuke because the quality is decreasing by the high salinity; the happenning of environment damage such as wallows as the impact of sand excavation and coastal ecosystem damage; the four factors as the main supporting damage of coastal boundary are profit oriented, soft monitoring and social control, the increasing of infra structure development
