Abstract
The Musi River, the longest river on the island of Sumatra, is widely used by the community as a transportation route and for various other activities. Therefore, the Musi River is a habitat for phytoplankton and can be a bioindicator of water quality. This study aims to determine the success of analysing the abundance, diversity, uniformity, dominance and potential of HABs phytoplankton downstream of the Musi River. Observations of 10 sampling stations found six genera from the class Bacillariophyceae (Bacillaria, Coscinodiscus, Ghemponema, Navicula, Skeletonema, Streptotheca), six genera from the class Chlorophyceae (Chlorella, Hydrodiction, Micrasterias, Pediastrum, Platydorina, Spirogyra), one genus class Cyanophyceae (Oscillatoria). The results of the analysis obtained an abundance of 18-483 cells/L, the diversity index (H') 0.89-1.57, uniformity index (E) 0.75-0.99, and dominance index (C) 0.25-0.46 with the phytoplankton genus in the highest abundance of Spirogyra and the lowest Bacillariophyceae. Furthermore, the results of the observations show that the physicochemical parameters are in a suitable category for phytoplankton growth and found several types of phytoplankton that have the potential for HABs (Coscinodiscus, Skeletonema, Oscillatoria).
