摘要：Tourism is a sector that is prioritized in various countries. Most of the tourist objects are distributed along the coast that intersects directly with those that result in the degradation of the ecosystem inside. The southern region of Bali is one of the regions that has experienced rapid development of tourism activities. The expansion of the tourism area in Tanjung Benoa occurs in coastal areas and directly contacts underwater ecosystems such as seagrass beds and coral reefs, which it have an impact on changes in the area of the ecosystem. Information about the form of distribution of underwater objects can be the first step in making ecological-based tourism policy. Satellite imagery can be used to detect shallow-water habitats. The purpose of this study was to determine the effectiveness of sentinel-2 A images to map shallow water habitat in densely packed tourist areas Tanjung Benoa. The results showed that there were three types of land cover in Tanjung Benoa area, such as seagrass, coral and sand, the accuracy results showed landsat 8 images had higher accuracy than Sentinel-2 A images with total accuracy of 74.83% and kappa accuracy of 46.59%. There are 8 types of seagrasses species in the coastal area of Tanjung Benoa, namely Cymodocea rotundata, Enhalus acoroides, Halodule pinifolia, Halodule uninervis, Halophila ovalis, Thalassia hemprichi Syringodium isoetifolium dan Thalassodendron Ciliatum .
