Land use is closely related to changes in the quality and quantity of river water. River damage due to changes in land cover is influenced by human activities in land use so that there is an increase in open and built areas. Percut River is one of the rivers flowing in the city of Medan, Karo district and Deli Serdang district, which receives the effects of industrial, residential and agricultural waste pollution. This study aims to analyse the water quality of Percut River both physically and chemically representing the upstream to downstream of the Percut River with various surrounding land cover. There are 5 sampling points on the Percut River. Analysis of river water quality was using the water quality index and pollution index. The water quality status of Percut River is slightly polluted. The results of the Percut River water quality analysis showed several parameters exceeding the quality standard based on government regulation PP No.82 of 2001 Class II namely the parameters COD, ammonia, phosphate. The value of each Percut River water quality parameter is different for each type of land cover or land use. Downstream areas are the areas that receive the greatest impact from pollution.
