Abstract
Phytoplankton function as an indicator of organic pollution and fertility of a waters. Water bodies are very sensitive because small changes can result in a real ecological effect. Situ Cipondoh there is ± 126.17 ha located in the city of Tangerang, Banten, Indonesia. Around Situ Cipondoh there are housing, hotels and restaurants and recreational tourism. This can lead to an increase in environmental pollution. Situ Cipondoh decreased by 15.83 Ha due to sedimentation and land use changes in the vicinity. This study aims to determine the level of pollution in the waters of Situ Cipondoh by analyzing phytoplankton with water quality mesured are DO, BOD and COD parameters. Analysis the community structure of phytoplankton are diversity index (H’) and saprobic index (X) The result of diversity index and saprobic index described the present status of the lake is lightly polluted.
Keywords: Phytoplankton, organic pollution, ecological effect, diversity index, saprobic index
