Abstract
Assessing marine water quality involves evaluating water conditions and identifying areas that may require further attention. In this study, the water quality of the Guimaras Strait was assessed using the comprehensive pollution index and geographic information system. Water samples were collected from 11 sampling sites for 1 year in the coastal waters of Bago City and Pulupandan and were analyzed in terms of nine parameters: pH, dissolved oxygen (DO), temperature, color, chemical oxygen demand (COD), nitrates, phosphates, total suspended solids (TSS), and fecal coliform (FC). The average comprehensive pollution index value from April 2018 to March 2019 was 0.1653, indicating a sub-cleanliness pollution level. It is recommended to conduct regular coastal water monitoring and share data via GIS.
