Abstract

Mangrove ecosystems play an important role as a natural protector of coastal areas against abrasion and wave threats, and generate indirect economic benefits in the form of coastal protection services. This study aimed to analyze the condition of the mangrove ecosystem and to estimate the economic value of the coastal protection services it generates in the coastal area of Simboro District, Mamuju Regency. The research was conducted from May to June 2026 using a quantitative descriptive approach. The area and distribution of mangroves were estimated through delineation of Sentinel-2 satellite imagery using QGIS software and verified through field surveys, while the economic value of coastal protection services was calculated using the Replacement Cost Method (RCM) based on the construction cost of a breakwater as substitute infrastructure. The results showed that the mangrove ecosystem in Simboro District has a cover area of 64.06 ha spread along 15,460 meters of coastline. Based on a unit construction cost of IDR 14,043,994.61 per meter, the estimated economic value of coastal protection services was IDR 217,120,156,671, or approximately IDR 217.12 billion. This value indicates that the presence of mangroves provides a substantial economic contribution through savings in the construction cost of artificial coastal protection infrastructure. This study recommends that mangrove conservation and rehabilitation be prioritized in the coastal management of Simboro District.
