Abstract
The Panasen River is located in the upper part of Tondano Watershed. This river has an important role including being used as an irrigation water source. The purpose of this study was to assess the water quality of the river as a source of irrigation water in terms of the value of Sodium Adsorption Ratio (SAR) and the quality standard according to Government Regulation No. 82/2001 class III.The method used was field observation and laboratory analysis for river water samples. The measured parameters were Na, Ca, Mg, as well as other chemical parameters. The measured data were compared to the Quality Standards according to the regulation and using the SAR formula. The results showed that the SAR of river water varied from 0.10me/l to 0.40me/l. The results of the chemical analysis of 30 water quality parameters indicated that they generally met the requirements, except the chlorine (0.03-0.26 mg/l) that has exceeded the quality standard according to Government Regulation No. 82/2001 class III (0.03 mg/l). The high concentrations of chlorine caused by domestic sewage that goes into the body of water. It can be concluded that the river water still meets quality standards for irrigation water except chlorine.
