Abstract
Coastline changes on the west coast of the Pandeglang Regency are caused by hydrooceanographic parameters and human activities. These changes can be observed through remote sensing. This study aimed to identify and map these changes. The shoreline of the Sentinel 2A satellite image was extracted using the Tasseled Cap method. The shoreline was then calculated using the Digital Shoreline Analysis System (DSAS) method, and field data were collected using Ground Control Points (GCP). The analysis of shoreline changes indicated the dominance of abrasion over accretion. The most significant abrasion occurred in Sidamukti Village at a rate of 26.65 metres per year, while the largest accretion occurred in Sukajadi Village at a rate of 24.92 metres per year. A comparison of the categories of coastline changes can indicate areas that are susceptible to large waves. This information can be used to provide both experience and knowledge to the people of the Pandeglang Regency. The study of coastline changes is an important reference for the development of coastal areas, harbors, tourism, and cultivation.
