Abstract
In attempt to know the trophic status and phytoplankton community in Juanda
reservoir this research was conducted. This research revealed that based on
secchi disk and concentration of Chlorophyll-a the Juanda reservoir have become eutrophic, with phytoplankton density was about 27,779-43,439 x 10-3 cell/l. The phytoplankton community was dominated by Synedra sp. (22.4-33.8%) and Microcystis sp. (10.2 –31.4 %;). However this result was about 1000 x bigger than previous publication which reported the phytoplankton density in Juanda reservoir was only about 621- 35,514 cell/l, and the phytoplankton community was dominated by Microcystis sp. which always > 85%. These differences were suggested due to using net-plankton in the sampling of phytoplankton.
