Bedadung River is one of the water sources in Jember Regency. However, the condition was in the category of polluted in heavy level at an urban area (i.e Sumbersari and Kaliwates Districts). Water quality monitoring was one method to pollution controlling efforts by the government and stakeholders. Water quality monitoring could be done with a. Water Pollution Index (WPI) described contaminating based on physical, chemical and biological parameters in the water. The focus of this research investigated land use impact for water quality of Bedadung River with Water Pollution Index (WPI) method. Water Pollution Index (WPI) used to input data consisting of physical, chemical and biological parameters. The parameters were physical, chemical, and biological. Sampling was carried out on 5 locations of the Bedadung River urban area segment (i.e Patrang, Sumbersari, and Kaliwates Districts) in 2016. Land use data was in 2010.
