Urban lakes are rapidly becoming vulnerable because of such as anthropogenic pollution and urbanization. Phytoplankton is classified as a biological indicator of lake status. Study was conducted to determined and compared diversity and functional group of phytoplankton including environmental factors in three urban lakes of Cibinong, West Java, Indonesia. The data was collected twice a month from July to October 2018. Three urban lakes showed a different water quality. Phytoplankton composition consists of Chlorophyta, Bacillariophyta, Chrysophyta, Cyanophyta, Pyrrhophyta, Cryptophyta and Euglenophyta division Chlorophyta is more diverse group than other divisions in those three urban lakes. High abundance of Chlorophyta was found in Situ Cibuntu. In Situ Lotus, high of abundance was represented by Bacillariophyta. Temporally, in August, the percentage abundance changes from Chlorophyta to Chrysophyta in Situ Dora. Based on the index diversity, Situ Dora is more stable habitat than Situ Cibuntu and Situ Lotus. The index diversity (H’) and Evenness (J) value of Situ Dora, Cibuntu and Lotus, H’: 1.41-4.03, J: 0.4-0.98; H’: 0.65-2.61; J: 0.2-0.76 and H’: 0.12-2.19, J: 0.11-0.57, respectively. The stability of habitat in Situ Dora was also indicated by the balance of phytoplankton functional group.
