Abstract

The pollution and environmental degradation in the Jagir River Basin (DAS) have prompted the need for sustainable river rehabilitation involving active community participation. As a strategic public resource, the sustainability of the watershed depends not only on the government's role but also on the community's willingness to participate in financing environmental improvements. This study aims to analyze factors influencing community willingness to pay (WTP) for the Jagir Watershed rehabilitation and development program, focusing on three main variables: income, education level, and family size. This study used a quantitative approach with a survey method and multiple linear regression analysis of 110 respondents in Ngagelrejo Village, Surabaya. The results showed that only income had a significant positive effect on WTP, while education level and family size did not show a significant effect. The community considered the river water quality to be inadequate and tended to be poor, and the PDAM water service was not fully reliable. Most respondents relied on various other water sources such as wells, gallon water, and refilled water. The low WTP score was also influenced by the perception that river improvement was the government's responsibility. This research contributes to the development of environmental socio-economic studies and forms the basis for participatory policies in watershed management.
