Abstract

The change water quality is closely related to abundance and compotition of phytoplankton so the existing of phytoplankton in water can give information about the water condition. The purposes of this research were getting information about diversity, abundance, distribution, structure community of phytoplankton in Sungsang water, definiting distribution of physic and chemical parameter in the water. The research about structure of community and distribution of phytoplankton in Sungsang, South Sumatra, had been done on April 2011. The research stations were determined by the Purposive Sampling method. The sample of phytoplankton was taken by plankton net with 20µm meshsize. Identification of Phytoplankton was performed by observing under a microscope and using phytoplankton identification book in laboratory. The result showed that phytoplankton which found were composed by 4 classes of phytoplankton, they are, Chlorophyceae, Dinoflagellata and Cyanophyceae. Generally, the Genus that found was Coscinodiscus, Skeletonema, Streptotheca, dan Desmidium. The value of phytoplankton abundance in each station are 48 cell/l up to 206 cell/l. Index of diversity (H’) ranged from 0,92 – 2,77, index of uniformity (E) ranged from 0,48 – 0,87 and index of dominance ranged from 0,19 – 0,66. The physic and chemical parameters, they are temperature, salinity, pH, nitrate and phosphate is classified as good, but the visibility and DO is classified as not good.
