ANALYSIS OF DOMESTIC WASTEWATER DISTRIBUTION FACTOR IN RIVER BRANTAS FLOW AREA MALANG CITYBekti Prihatiningsih, Zaenal Kusuma, Agus Suharyanto and Amin Setyo LeksonoAbstract Increased pollution that occurs due to domestic activities that produce domestic wastewater has not received attention as the handling of domestic solid waste and industrial waste. The mapping results of the distribution of domestic wastewater in the Sawojajar and Sumbersari villages found the level of pollution with an IP value of 4.05 and 4.02 which was close to the level of moderate pollution. This condition must be taken into consideration as domestic wastewater is produced continuously and discharged into the drainage system. If without management, it will spread and reduce the quality of the environment. For this reason, a study is needed about the factors that are most influential in the distribution of domestic liquid waste. By using the Delphi and AHP analysis methods, it was found that the factors that influence the distribution of domestic liquid waste in the study area (weight) were pollutant load (0.4509), population (0.1657), discharge (0.1307), accessibility (0.1080), land area (0.0909) and drainage system (0.0530).
