Semarang City, is Capital of Central Java Province Indonesia, has many watersheds which it's still unknown about water quality, water class and function. The other hand, the people need to water resources for some utilization. Babon Watershed is one of them, and located at north slope of Ungaran Mount. The main river is about 33,76 km length. Base on its function, from upstream to downstream, Babon Watershed can be divided into 8 segments. Data collection of river water quality is done by taking samples on the representative location. The parameters analysed included physical parameters (TDS, TSS, temperature, DHL, brightness), inorganic chemical parameters (pH, BOD, COD, total P, NO2, NO3, N total, NH3, Cl, F, Sulphate, H2S, chlorine free, sulfur as H2S), organic chemical parameters (oil-fat, detergent as MBAS, phenol), and biological parameters (fecal coliform and total coliform). According to the analysis results obtained that in segment number I, II, III of Babon Watershed is recommended to function in class II, while segments number IV, V, VI, VII, VIII are recommended to function in class III.
