Abstract
Land use and land cover (LULC) changes are two main factors contribute to the decreasing water quality. This research aims to assess the impacts of LULC changes on the river basin towards water quality of Cirarab River. This research applied GIS analysis with LULC data changes from 2013 to 2018. The potential pollution load originating from residential on the river basin was calculated and compared to the maximum pollutant load. Water samples were collected five times a day in three locations. The result showed residential and industrial areas increased respectively of 110.08ha and 388.37ha; while shrub/vacant land decreased by 407.15ha. Potential pollution load amounted to 2615.78 kgBOD/day and 3713.87 kgCOD/day. This study found almost all monitoring points of COD and BOD parameters exceeded the required quality standard. Water samples collected from river basin with shrubs/vacant land has relatively better water quality compared to those collected from residential and industrial areas.
