Cikakembang River is one of Citarum River tributaries which become a location of wastewater discharges from industry, agriculture, and domestic area. This matter causing a pollution in Cikakembang River itself with the status highly polluted in the downstream and intermediate polluted in the upstream. The differences of land use around Cikakembang River is predicted to cause different characteristic of pollution from upstream to downstream. In order to depicts the pollution, this research objective is to determine water quality profile of Cikakembang River based on physical, chemical, and acute toxicity aspects. To solves water pollution problem, aeration method is applied. Aeration will increase dissolved oxygen concentration which leads to pollution reduction that comes from different sources of pollutionxz. Results from this research show that the quality of Cikakembang River water is vary from upstream to downstream. Parameter of COD, TSS, and total phosphate have an increasing trend from upstream to downstream. Meanwhile, TDS, amonium, nitrate, phenol, pH, conductivity, and temperature has maximum value in certain sampling point, affected by wastewater discharge from the area around the point. Furthermore, for dissolved oxygen, the concentration is decreases from upstream to downstream. In the matter of acute toxicity, the highest toxicity value located near the paddy field. It shows that the main source of pollution is from agricultural area that could contain pesticide which has high toxicity value. After aeration applied, all physicochemical parameters, except TDS, conductivity, and nitrate, has quality improvement from 4 percent (total phosphate) up to 800 percent (dissolved oxygen). Application of aeration is significance to reduce water pollution. (p value=0,02).
