Modeling of coastline change by viewing trends from the abrasion and accretion rate in karawang regency

Coastal areas are a region with geophysical phenomena that are very complex and dynamic with various physical aspects as a driver. One of the easiest parameters to be observed from the dynamics that occur in coastal areas is a change in the coastline. Karawang Regency as one of the regencies in West Java Province, directly bordering the Java Sea. This causes that along the northern part of Karawang Regency is a coastal area that is very vulnerable and has the potential for the phenomenon of shoreline changes. This study aims to predict the shoreline change model that might occur on the northern coast of Karawang Regency from 2018 to 2028. The change in coastline was analyzed using remote sensing data through overlay analysis and then the prediction model was made by looking at the trend of abrasion and accretion rates from the previous year. The results of the prediction model show that from 2018 to 2028, abrasion will occur with a total area of 118.50 hectares. As with abrasion, accretion will occur with a total area of 161.36 hectares along the northern coast of Karawang Regency in a span of 10 years.
