The Kuranji watershed has a complex problem which cannot be studied with a single scientific approach. In addition to an ecological approach it is also necessary to consider social and economic influences. Conserving areas that have a negative impact on watersheds, such as critical lands, is one of the efforts made to conserve watersheds will reducing costs and speeding up the recovery. The aim of this research is to estimate the economic value of the water yield of the Kuranji watershed on land conservation efforts. To get the economic value of water yield in the watershed, the non-market price approach method is used with the Contingent Valuation Method (CVM). The results showed that there were 356.10 ha of critical land in the Kuranji watershed that could be conserved. The value of water yield in existing land use conditions is greater than water yield in land use conditions influenced by conservation efforts. In this study, it was determined that the estimated economic value of water yield in the Kuranji watershed is 272 IDR/m 3 of water. This is supported with a conservation value of 80% of critical land.
