Analysis suitability of river tubing tourism based on characteristics and water quality of the Kranji River Semarang.

Kranji River, located in Jatirejo Village, Gunung Pati, Semarang, has the potential for river tubing tourism. The purpose study was to determine the condition of river characteristics, water quality and the status of water quality used in river tubing tourism. The research on the Kranji River in September 2020 using survey method and river characteristics data using Digital Elevation Model data remote sensing method then processed ArcGIS software. The water quality method uses the Pollution Index (PI) stated in the Decree of State Minister Environment number 115 of 2003. The quality standard used is class 2 water quality as stated in PP number 82 of 2001. The results data of width, discharge and slope, respectively, obtained an overall of 8.75 m, 2.11 m3/second and 17.78. This value is close to the ideal value of the required characteristics. The water quality parameters measured temperature, TSS, pH, DO, BOD, COD and Escherichia coli bacteria with sequential results of 29.27°C; 0.12 mg/l; 7.34; 9.36 mg/l; 6.82 mg/l; 22 mg/l and 2.725 in/100ml. The results based on the measurement of IP value of 2.73 indicate the quality status of the river water is lightly polluted. The status of water quality has been and is still suitable as river tubing tourism. [ABSTRACT FROM AUTHOR]
