ABSTRACT
Morosari river located in District Sayung, Demak is used for the disposal of domestic and industrial waste, traffic, fishing boats, tourist areas and fisheries activities. And may affect the water quality. The study was conducted in April-May 2014, aimed to determine the condition of the river by chlorophyll-a, nitrate, phosphate, and phytoplankton community structure at different locations. Other variables included temperature, currents, depth, transparency, pH, salinity, and dissolved oxygen. This study used four stations with three replications. Analysis of the data used cluster analysis and the Kruskal-Wallis non parametric analysis. The results showed a significant difference in the content of chlorophyll-a and phosphate each station, while the nitrate content there was no significant difference. The highest similarity based on the phytoplankton community was between residential areas and traffic areas fishing boat, while the lowest is similarity was in industrial waste disposal area. The abundance of phytoplankton included in the category of moderate abundance, phytoplankton diversity and evenness index were low. Based on the content of chlorophyll-a and nitrate Morosari river waters belong to the oligotrophic waters, while based on the phosphorus content included into the mesotrophic waters.
Keywords : Chlorophyll-a; Nitrate; Phosphate; Phytoplankton; Morosari River
