Abstract
This research was conducted to determine the water quality of Situ Ciburuy based on the plankton community as water quality bio-indicator. This research used the survey method and the observation result data were analyzed descriptively. The abundance of phytoplankton is about 340 – 8913 ind/L indicates that the abundance of phytoplankton is moderate and the abundance of zooplankton is about 7 – 30 ind/L indicates that the abundance of zooplankton is low. The Simpson diversity index for the phytoplankton group ranged from 0.29 – 0.33 and the Simpson Diversity Index for the zooplankton group ranged from 0.42 – 0.56 while the Simpson Dominance Index for the phytoplankton group ranged from 0.67 – 0.71 and the Simpson Dominance Index for zooplankton ranged from between 0.44 – 0.58 which indicates Situ Ciburuy is in an unstable condition. Based on the value of the Saprobic Index ranged between (-0.2) to (0). Situ Ciburuy belongs to α / β – mesosaprobic phase and categorized in the moderately polluted category.
