Spatial Analysis For Index Identification Surface Water Pollution

Abstract

Surface water pollution is an essential problem for policymakers, this is because water is a source of life for the environment. One of the causes of pollution is the company's contribution  to waste disposal. The purpose of this research  is to identify local pollution points and their pollution status and to map the location of the  company to determine the possible contribution of  the company to water pollution using a Web-based Geographical Information System (Web-GIS) technology. The data used in this study came from  the Environmental and Sanitation Service (DLHK) Sidoarjo Regency. The Pollution Index (IP) method  is used for the spatial analysis process based on parameters TSS, DO, BOD, COD, Phosphate, Total  Coliform, and Fecal Coliform. The results of  spatial analysis using the IP method get an  accuracy value of 91% which states that this  method is suitable to be recommended for further research with the same data behavior
