Plankton research in the Cisadane river area of Tangerang City was carried out from July to September 2018, aimed at studying the structure of phytoplankton and zooplankton communities in these waters. Research uses survey methods, sampling is done by purposive sampling. Samples were taken from three stations determined by filtering 40 liters of water at each station, namely in the city park area (station 1), residential area (station 2) and industrial area (station 3). Plankton analysis was carried out at the Integrated Biology Laboratory of Palembang PGRI University. The results of the study found 19 types of phytoplankton and 10 types of zooplankton. The highest abundance of phytoplankton and zooplankton is at station 1 (city park area) with a value of 16.88 ind / liter and 8.75 ind / liter respectively (at station 3). The plankton dominance index in each station has a value below 1, so that it can be said that no individual plankton dominates the waters. Phytoplankton and zooplankton diversity index in the three stations are categorized as moderate, with a value of 1.71 - 2.41.
