Tripikon is a pipe usage model as a means of modified infiltration ditch as an effort of water pollution minimization. The purpose of this research was to analyze the decrease of Biological Oxygen Demand (BOD) and Most Probable Number (MPN) Coliform level of domestic waste in tripikon infiltration ditch at narrow field. This research was an experimental research with a group of pre and posttest design. The result of this research was it indicated a decrease of BOD level in tripikon, thus, it was in accordance with Minister of Environment and Forestry Regulation Number 68 in 2016 concerning with domestic waste quality standards, which the maximum was 30 mg/ L. Likewise MPN Coliform level in infiltration ditch was still below the maximum level of waste water (3000 per 100 ml). The decrease of BOD level was 36.8%.
