Abstract

– Ciliwung river is one of the most polluted rivers because it's used by many citizens of Jakarta for Industrial and household activity. One of biological parameter that's can be used as an indicator of environmental changed is Phytoplankton. The role of phytoplankton in aquatic ecosystem that is as primary producers, this is because phytoplankton have the ability to photosytensis. This study was conducted from February to July 2016. Ciliwung clean activity is implemented from Rindam Jaya, Condet to Bidara Cina. Post-activity clean ciliwung value of dissolved-oxygen from upstream Ridam Jaya, Condet to downsream Bidara Cina decreased, so that it can affect the diversity of phytoplankton. This difference is thought to give a picture of the diversity of different phytoplankton community so that samples were taken of phytoplankton in two points each with three repetitions. Phytoplankton sampling method was used Horizontal sampling method and samples were identified using Sedgewick Rafter Cell Counting (SRCC). Based on the research, the total abundance in Rindam Jaya is higher than in Bidara Cina with consecutive numbers 2511 Ind / L and 1495 Ind / L. The results of phytoplankton identification were found in the study sites of 53 genera belonging to 5 divisions namely, Bacillariophyta (20), Chlorophyta (16), Chrysophyta (5), Cyanophyta (8), and Rhodophyta (4). The abundance of phytoplankton at Rindam Jaya station is higher than in Bidara Cina. Keyword - Phytoplankton, Ciliwung River, Indicator Biotecnology
