Abstract
Tamiang Bay is a bay located in Kotabaru, South Kalimantan, Indonesia. This bay has a fairly large area and is known as an area that has quite large coal mining activities, so it has become one of the case study locations in research related to the impact of coastal pollution due to coal waste. Tamiang Bay is also known to have high biodiversity, especially around the coastal areas and sea waters, so that bad conditions due to pollution can have an impact on the balance of the marine ecosystem and the survival of the organisms in it. This article discusses the condition of the aquatic environment by utilizing remote sensing technology through the concentration of water turbidity, suspended solids, chlorophyll, and water surface temperature in order to determine the condition of sea water on the coast of Teluk Tamiang, Kotabaru Regency using Sentinel 2 and Landsat 8 images.
