The index of thepollution was calculated and compared to the Governor Regulation Number 8 of 2007 while the community perception onthe waste impact of the kacang koro washing was analyzed using percentage formulae.The finding of the study shows that the pollutant properties of of the waste water have exceeded the maximumlevel of quality standard covering parameters of TSS, COD, BOD5 and ammonia. The pollution of the Timuhun irigationby the waste water from the kacang koro washing is indicated by the high property of the water quality parameter onBOD5 and COD. Based on the pollution index (PI), it was found that the water quality of Timuhun irigation reached amild pollution in all criteria of water quality of class I, class II, class III, class IV except the origin location which is stillin good condition.
