Abstract
The Musi River estuary is a part of the Musi River. This estuary is located in Sungsang and was the meeting point of some tributaries to the Bangka Sea. It is necessary to determine the chlorophyll-a concentration in the Musi River estuary using effective methods. The purpose of this study was to investigate the distribution patterns of chlorophyll-a in the Musi River Estuary using multitemporal sentinel 2a imagery. The study was conducted in February 2020 using 2018-2020 Sentinel-2a imagery. Methods were developed to achieve the objective. The method of field survey and processing of optical image data. These methods showed a correlation between insitu results and image processing results using the Pentury algorithm (1997) of r = 0.563, indicating a high relationship. The RSME value of the Pentury algorithm (1997) is 0.01, which proves that the result is very accurate. In 2018, the distribution of chlorophyll-a was rather low in the riverine areas and higher toward the sea. In 2019 and 2020, the distribution pattern of chlorophyll-a was almost identical, i.e. chlorophyll-a tended to be high in the river basins and lower toward the sea.
