Abstract
This study examines shoreline changes in the Pulau Merah area, Banyuwangi, a coastal region with high dynamics influenced by waves, tides, ocean currents, and human activities that potentially trigger both erosion and accretion. The background of this research is based on the importance of monitoring coastal conditions to maintain ecosystem balance, protect community settlements, and ensure the sustainability of tourism, which is the main attraction of Pulau Merah. The literature review indicates that the use of Landsat 8 satellite imagery and Geographic Information System (ArcGis) technology with the Euclidean Distance method is an effective approach to detecting shoreline changes spatially and quantitatively. The research method utilized secondary data in the form of Landsat 8 imagery for the 2015–2025 period, along with primary data obtained from field surveys to verify the actual conditions at the study site. The analysis was conducted through shoreline digitization, distance measurement of changes along 20 observation transects, and the development of thematic maps and shoreline shift graphs. The results of the study show significant variations in shoreline changes, with the greatest erosion reaching –107.30 m on Transect 3 in 2016 and the highest accretion of +69.15 m on Transect 3 in 2023. These changes were driven not only by ocean waves, tides, and currents, but also by human activities around the coast. Furthermore, the mapping results reveal that shoreline changes impact the coastal ecosystem, such as disrupting the habitat of coastal biota, and pose risks to the economic and tourism activities of local communities who rely heavily on the preservation of Pulau Merah beach. Keywords: Shoreline Change, Banyuwangi Coastal Area, Landsat 8 Satellite Imagery, NDWI
