- Rawa Pening is a natural lake that has 17 inlet (rivers that lead water into lake )and one outlet Tuntang River Inlet and outlet of Rawa Pening Lake have differences in phisio-chemistry factor and covering of plant water. Palnkton is one of organism that influenced by this condition. The aim of this research is to establish structure community of plankton in inlet and outlet Rawa pening Lake. Sample was taken from 7 inlet (the downstream of Segalok, Torong, Panjang, Galeh, Rengas, Kedungringis and intercourse of Parat, Legi and Muncul downstream). Sample of outlet taken from upstream of Rawa Pening Lake, around of port and before bridge. Sample then analyzed by diversity index, similarity index, equality index, and total individu per liter. Seventy seven plankton were found in inlet and outlet Rawa Pening Lake, Sixty five species are phytoplankton and contains 0f 22 species Chlorophyceae, 12 species are zooplankton and contains of 10 species Rotifera also one species Sarcomatigophora and one species of Copepoda. Based on diversity index, equality index, and total individu the community structure of plankton in inlet is relatively stabil than in outlet Rawa Pening Lake. The similarity index showed that level of species similarity is low. This is indicated that structure community of plankton in inlet and outlet is different
