Abstract

This research was conducted in Cisadane River middle segment to the downstream started from Teuku Umar bridge and finished at Muara Tanjung Burung, Tanggerang Regency. The research was started from February - June 2021. The Purpose of this research are to calculate and determine the concentration of nitrate and phosphate in the water according to the characteristics of the Cisadane River, and to determine the flow conditions in the middle part of the Cisadane River through the distribution pattern of parameter concentrations and simulated with using the Qual2Kw method. This method used to identify pollutant sources which done by conducting surveys, water quality analysis that carried out in accordance with SNI and compared with quality standards according to PP No. 82 Tahun 2001, and pollutant load capacity analytics (PLC) of nitrate and phosphate using the Qual2Kw model. The result of identification of potential pollutants in Cisadane River middle segment to the downstream are dominated by group of villages, agricultures, industries and domestic activities, and stalls. The results of water quality analysis for nitrate parameters are ranged from 0,17 mg/L - 0,99 mg/L, and phosphate parameters ranged from 0,2 mg/L - 1,3 mg/L. The average of PLC for nitrate parameters was 77339,39 kg/days, and phosphate was 4986,49 kg/days.
