【 摘 要 】

Indonesia is an archipelagic country that has diverse tourism potential, one of which is the island of Bali. The island of Bali is famous for its tourism potential to the World Level, especially the potential for natural and cultural tourism that is not found in other countries. Tourist visits to the island of Bali, from various countries, always increase every year. The increase in the number of tourists has triggered the tourism industry business players to build tourism facilities such as hotels, restaurants, shopping centers, and other facilities, thereby causing an increase built-up area in the coastal tourism area. This study aims to analyze the spatial pattern of built-up land through the transformation of the built-up land index (NDBI) and correlate it with the vegetation index (NDVI, SAVI) and the water index (NDWI). Data analysis using Remote Sensing method using a cloud-based computing platform, namely Google Earth Engine (GEE), on Satellite Imagery Sentinel 2, acquisition on 2016 and 2021. The results of this study indicate that there is an increase in the pattern of built-up area in the Southern coastal area, Tourism Area. The increase in built-up area causes a decrease in the level of vegetation density and increase the level of wetness of the soil surface.
