Abstract

Determine the relationship between physic-chemical water quality characterictics of phytoplankton diversity. Phytoplankton and water samples were taken in Ngenep, Nyolo, and Balittas. Each pool was taken three times. Samples were taken using 5 liters of water sampler, then filtered with plankton net and observed with Sedgewick Rafter's Counting Chamber at 500 visual fields under a microscope 10 x 25 times enlargement. Data collection for each station includes community structure, diversity and water quality. Then the data was analyzed by ANOVA. The results showed that 14 phytoplankton species were found in Ngenep, Nyolo and Balittas ponds. Phytoplankton (H ') diversity index in three ponds at moderate levels (1 <H' <3). The mean value of phytoplankton ranged from 0.67 to 0.85 while the phytoplankton domination index ranged from 0.19 to 0.37. The Spyrogyra genus is more dominating in the Balittas and Nyolo ponds while in Ngenep the Fragillaria genus is more dominant than other genera. Physico-chemical water quality parameters (temperature, turbidity, conductivity, pH, and DO,) in the three Ngenep ponds were not significantly different (P> .0.05), but affected phytoplankton diversity and community structure. Clustering analysis shows the correlation pattern between community structure, phytoplankton diversity with physico chemical water quality parameters.
