Abstract

This research aims to analyze the water quality condition of Kaliaji river based on physical and chemical water river factors. The analysis was conducted on observation points in downstream by testing the  water  pollution  parameters  compared  to  the  water quality  standard  of  water Pollution Control for Class III. The parameters observed in this study were TSS, TDS, BOD,  COD, Phosphat, Nitrat and Flourida. Determination of water quality status using pollution index method was compared to water quality standard Governmental Regulation No. 82/2001 class III.  The  water  quality  of  Kaliaji river  from  downstream  observation points  generally had no decreased quality according to the parameters which fulfill the quality standard. The carrying capacity index of Kaliaji river was categorized as very good because the index value was still below 1. Prediction result of the simulation of  carrying capacity index was increased along with increase in the number of industries. Further this situation will have already exceeded the ideal value in 2031. The implication of this conclusion will be the policy makers need to conduct environmental monitoring on a regular basis. The provision of green space in industrial areas needs to be directed at the flood retardant plant planting program.
