Abstract
Environmental factors can influence the community structure of phytoplankton in water. This study aimed to assess the abundance, diversity, uniformity, and dominance of phytoplankton from the Musi and Banyuasin river estuaries influenced by environmental factors. The study was conducted by collecting water quality data at 12 stations. Water samples were collected with a plankton net measuring 20 µm. Statistical analysis used an independent sample t-test and principal component analysis (PCA). Musi River Estuary has an abundance of 23–39 cells L-1, low diversity, high uniformity, and not dominance. Banyuasin River Estuary has an abundance of 27–441 cells L-1, low diversity, moderate uniformity, and dominance. Based on variance analysis, the two river estuaries have water quality and abundances that are not significantly different. The results of the PCA analysis indicated that salinity, pH, and phosphate were the main determinants of the causal relationship between phytoplankton abundance and water quality indicators in the Musi River Estuary. While the Banyuasin River Estuary by current speed and light intensity.
