Abstract
Coastal areas have continuous change due to the interaction between sea and land, which causing abrasion and accretion generally. Indramayu Regency is one of the regencies that has sea waters on the north coast of Java and has a coastline of around 114 km. The coastal of Indramayu regency has characteristics as a sandy beach which has a dominant process of abrasion which is triggered by the process of digging beach sand and converting mangrove land into ponds. Obtaining changes in the coastline and beach materials, we applied remote sensing observation to obtain shoreline data periodically. Currently, satellite images support the availability of Landsat data in a relatively short time and large coverage area. The use of remote sensing technology is supperior to support field surveys with limitation of time and observation coverage. We have used Landsat 7 and 8 images within the past 10 years to detect coastline changes and predict abrasion in study area based on Normalized Difference Water Index (NDWI) and Digital Shoreline Analysis System (DSAS) methods. Preliminary results from the analysis that has been carried out indicate shoreline changes that are dominated by abrasion. Abrasion occurs almost along the coastline, and accretion only occurs at a few points. This is triggered by the characteristics of the coast, as well as the land use being converted.
