A study on plankton diversity in Lake Buyan is very important to be undertaken. Thisis related to the fact that it is frequently mentioned that its condition is getting worse, itscapacity decreased because of sedimentation and its fish density is decreasing.Since the surrounding of the lake has been mostly utilized for agricultural activities,and settlement is getting dense there, it is likely that pollutant as well as untreated dischargedwater has flushed into the lake.Results of the study showed that there were 33 plankton species there prior toEichornia being cleared from the lake. The species richness decreased to 26 after clearing.

The first factor is the type of organik fertilizer (A) with compost (A1), cow manure (A2) and goat manure (A3). The second factor is the concentration of organik fertilizer (B) which is 0 g/polybag (control) (B0), 500 g/polybag (B1), 1,000 g/polybag (B2) and 1,500 g/polybag (B3). Parameters observed is plant height, number of leaves, number of branches, flower initiation time, age of the plant at harvest, number of fruit crops, fruit length,fruit weight, and fruit diameter. Data were analyzed using Analysis of Variance (ANOVA) and continued with Duncan Multiple Range Test (DMRT) analysis. The results showed that the treatment of goat manure and a concentration of 1,500 g could increase all research parameters. The combination of goat manure with a concentration of 1,500 g gave effective results on the growth and production of eggplant.
