Abstract
Pamulihan is one of the District in Garut Regency that has a function as industrial, recreation and conservation area. These activities may have an impact to the environmental, especially to the river. Cibatarua River which located in Pamulihan District may be affected by pollutant. The research objectives are to analyze the water quality based on Government Law No. 82/2001 and calculate the pollution load and pollution load carrying capacity of the Cibatarua River based on Environmental Agency Law No. 113/2003. Water quality parameters include Total Dissolved Solid (TDS), Biological Oxygen Demand (BOD5), Chemical Oxygen Demand (COD), pH, Oil and Grease and Dissolved Oxygen (DO). The results showed that BOD5 and oil and grease were exceed the standard based on Government Law No. 82/2001. The pollution load for BOD, COD, pH, oil and grease, and DO were 1.151.712 kg/day, 3.455,13 kg/day, 28.792,8 kg/day, 10.365,40 kg/day, 1.151,71 kg/day and 4.606,84 kg/day respectively. Meanwhile the pollution load carrying capacity for each parameters were 1.094.126, 4 kg/day, -1.382,05 kg/day, 12.910,69 kg/day, 1.600,87 kg/day, -1.151,71 kg/day and 0 kg/day respectively. Our recommendation to improve the river quality including wastewater management, reducing pollutant release to the river, and implementing biotechnology to reduce water pollution in River.
