Abstract
Water quality greatly be affected by human activities, such as sand mining, industrial waste, agricultural and household waste. Bodies are part of aquatic ecosystems. In aquatic ecosystems, phytoplankton is the primary food source for aquatic animals. Phytoplankton are plants whose life float and float on the water surface. Phytoplankton can be used as bio-indicators to determine water quality. This reasearch aims to determine the relationship between the distribution of phytoplankton in the water quality. The reasearch was conducted in cimanuk rivers, Garut, West Java. The results were obtained 76 kinds of phytoplankton with 5 different classes, namely: Bacillariophyceae, Chlorophyceae, Euglenophyceae, Cyanophyceae, and Cryptophyceae. Fitopalnkton distribution measured by the abundance (1.077-1710 individual / l), diversity index (2.6014 to 2.9184), evenness index (0.8651 to 0.8797), dominance index (0.8912 to 0.9255) and sprobik coefficient (0.61404 to 1.0). Based on saprobic and correlation coefficients person shows that the relationship between water quality (the intensity of light, brightness, current speed, wind speed) with the distribution of phytoplankton while the pollution level at the level of lightly polluted
