The aim of this research is to study the capability of Myriophillum sp. as biofilter in the drinking water treatment plant. The raw water taken from Situ Cibuntu located in the Cibinong Science Center area, pumped into 5 Seri-tanks of 34 ml/minutes flow rate. Each tank had 35 l of volume, and filled by 7 l of sediment, 28 l of raw water and 10 pieces of Myriophillum. All these components come from Situ Cibuntu. Water samples taken from tank 1, tank 3 and tank 5 were analyzed for microbiological, physical and chemical parameters. This research shows that Myriophillum sp. were able to elliminated completely the total amount of coliform and fecal coliform fed to the seri-tanks. The pH level slightly increased from 6.45 to 6.76, the turbidity decreased from 14 NTU to 1 NTU, and the dissolved oxygen (DO) increased from 3.36 mg/l to 3.42 mg/l. Meanwhile, nitrite and total nitrogen concentration decreased from 0.0407 mg/l to 0.0063 mg/l and 2.72 mg/l to 0.9957 mg/l, respectively. Other parameters such as phosphate, total phosphorous and COD tended to decrease from 0.0737 mg/l to 0.0148 mg/l, from 0.1379 mg/l to 0.0603 mg/l and from 11.32 mg/l to 8.89 mg/l, respectively.
