This research studied about photocatalysis that used TiO2 0.1% as catalisator to polluted water from Waduk Pluit, Muara Baru, North Jakarta. In order to decrease polluted agents like surfactant, KMnO4 organic, and ammoniac that will use as source of clean water. Research was conducted in batch reactor about 30x20 cm and used UV-C 15 watt x 2 lamps, and TiO2 as suspension. In this research, batch reactor that contained standard water was supplied by air with aerator 220v/100v 18 watt. Result showed that photocatalysis with TiO2 0.1% as catalisator decreased surfactant and KMnO4 organic about 80.98% and 9.48%, respectively. In contrary, ammoniac was increased about 325% Pollutants content in processed clean waterwere about 0.12 mg/l, 35.5.mg/l, and 4.93 mg/l, respectively. Result were met requirement for clean water standard as Health Ministry Decree No. 416/MENKES/PER/1X/1990 about clean water quality recuirement and controlling.
