【 摘 要 】

Phytoplankton can be used as an indicator for water environment quality in the watershed area. This research was conducted in Garang Watershed, Central Java, Indonesia. The aims of this research are to study the environmental assessment of Garang Watershed Central Java, Indonesia using phytoplankton diversity and their relationship to water quality. Sampling location was determined based on the Governor Regulation of Central Java Provincial No. 156/2010 about the segmentation of Garang Watershed. Plankton Net No.25 was used for collecting phytoplankton in Garang Watershed. Phytoplankton density ranged from 13 to 53 ind/L. The number of species in the range of 4-8. Diversity index in the range 1.07-2.06. The result of diversity index shown that this rivers is lightly polluted. Phytoplankton stabilization was moderate while phytoplankton evenness was spread. Water quality index in this research are: Phosphate, Nitrate, Nitrite, Ammonia and Fe.
