Derawan Island is one of the inhabited islands in the Derawan Archipelago. Derawan Island is located in the Sulawesi Sea and is famous for its marine diversity welcoming a tourist attraction with high interest from the community. CDOM (Colored Dissolved Organic Matter) is a colored dissolved organic material that is one of the water quality parameters that functions as an absorber of Ultraviolet light that harms marine life and as an indicator of the color of seawater. The distribution of CDOM values by human presence and supporting physical factors such as rainfall, water depth, and benthic habitat. The distribution of CDOM carried out in this study was based on Sentinel- 2 A image data in 2019-2021 using the wave ratio algorithm (a440) nm. Algorithm validation uses field survey data conducted on 2 – 5 December 2021. The Results Water samples were tested in the LIPI laboratory. With the results (R2 = 0.14) and (RMSE = 0.39). The analysis used in this study is descriptive analysis with a spatial-temporal approach and descriptive statistical analysis using R-square tests. The data processing results showed that the most influential physical factors are water depth and benthic habitat
