摘要：Phytoplankton in the sea has an important role in the food chain and is responsible for primary production. The abundance and number of phytoplankton types will indirectly affect the fertility level of a water. This study aims to determine the presence of phytoplankton in terms of density and various diversity indices like Shannon-Wiener Diversity Index (H’), Evenness Index (E), and Simpson Dominance Index (D) in estuary Banyuasin, South Sumatra. The study was conducted in September 2017 at eleven stations. Examples of phytoplankton are taken on the surface of the waters by using a cone-shaped plankton net with a diameter of 30 cm, a length of 100 cm and a mesh size of 30 µm. The study indicated the availability of 17 phytoplankton genera from the Bacillariophyceae class, and there was high density of the Skeletonema, with a composition of 98.71%. The values of H', E and D showed the existence of unstable phytoplankton community structure condition. The Shannon-Wiener diversity index value in this study ranged from 0.02 to 0.87, which means a community with low diversity, evennes values ranging from 0.01 to 0.25, meaning communities with uniform uniformity and high dominance values ranging from 0.67- 0.99.
