Abstract


The Krueng Baro River is a surface water resource that is widely used by the people of Pidie District for various activities. These various activities have the potential to have a negative impact on the river water itself. Precaution to protect and control water pollution in the Krueng Baro river must be implemented so that water quality standards are maintained. The research aims to assess the water quality status of Krueng Baro River in Pidie District, based on the parameters Odor, Temperature, TSS, DHL, COD, BOD, DO, pH, and Total Coliform. Each Parameter were analysed using Water Quality Index (WQI) and Environmental Pollution Index (PI) to determine the surface water status. The results of data analysis using PI index in 5 different sections showed respectively: Section 1 - IP value of 0.73, Section 2 - IP value of 0.70, Section 3 - IP value of 0.69, Section 4 - IP value of 0.75, and Section 5 - IP value of 1.44. At Section 5, the water quality of the Krueng Baro River is slightly polluted which is caused by the concentration level of BOD exceeding the predetermined quality standards. While using WQI Index, the Krueng Baro River resulting 66 scores, which was in the Moderate category. In conclusion, all parameters measured in Krueng Baroe surface water still met the Government Regulation No.22 Year 2021 Class II, excluded BOD parameter in Section 5.
