Mapping of Communal Waste Water Treatment Plant User Group in Citarum River Areas Using Geographic Information System

Citarum River is the largest and longest river in the province of West Java. The Citarum River flows along 269 km which starts from Situ Cisanti and empties into the Java Sea. The river is contaminated due to waste dumped into the river, one of which is an industrial waste. Thus, the local government needs to provide a Waste Water Treatment Plant (WWTP) that can be used simultaneously by several adjacent industries. The proximity between industries can be seen through mapping of location points using Geographic Information Systems (GIS). This study aims to design a web-based GIS application for determining groups of industries that will use the WWTP simultaneously. GIS application is designed to map industrial location points and placement of WWTP through determination of location coordinates on Google Maps API. Users of this application can see the display of groups of communal WWTPs as well as points that are in a certain area of coverage.
