Abstract
The increasing population and activities carried out on the banks of the Cidurian River has an impact on increasing pollutants that enter the river so that the quality of river water decreases.This study aims to determine the effect of the pollution load that enters the river from domestic,agricultural and livestock sectors on the Cidurian river water quality index.Calculation results show that the Cidurian River Water Quality Index ranges from -59 to -14,which is heavily polluted to moderately polluted with heavily polluted locations in Kopo District. Likewise with the results of the calculation of pollution load, the highest value of pollution load is in Kopo District with the ratio of the domestic sector 56%, agriculture 16,54% and livestock 27,46%, respectively.Based on these calculations, it can be concluded that the Cidurian River Water Quality Index in the Serang Regency segment is strongly influenced by pollution load from the domestic sector compared to agricultural sector and livestock sector in all monitoring locations.Hence it is necessary to construct and operate a domestic wastewater treatment plant in densely populated areas, especially in Kopo District to reduce the pollution load from domestic sector which in turn is expected to increase the Cidurian River Water Quality Index.
