Remote sensing data from Sentinel 2 satellite imagery is widely used in environmental quality analysis regarding water quality data, where two of the parameters that exist in analyzing water quality are the parameters of the water quality including chlorophyll-a and Total Suspended Matter (TSM). This research focuses on the South East Bali region, which is a region with high biodiversity and is vulnerable to environmental change. Thus, this research can provide important information about environmental conditions in the region. The Sentinel-2 satellite imagery data used in this study is data at level 1C. Sentinel-2B level 1C satellite image data, namely data recording on October 10th 2018, November 8th 2020. Sentinel-2A level 1C, namely data recording on November 3rd 2022. The highest chlorophyll value is found in the rainy season, namely in the recording data November 8th, 2020 with a chlorophyll-a value of 43.65 mg/m3. The highest TSM value is found during the transitional season from the dry season to the rainy season, namely in the recording data on October 10th 2018 with a TSM value of 42.77 mg/L. Despite these elevated values, TSM concentrations above 25 mg/L are generally considered to have limited impact on fisheries, suggesting that current sediment conditions are not likely to pose a significant threat to fishery activities in the region.
