ABSTRACTMine void is a problem that abandoned mines after mining ends The loss of function of the mine void water as raw water resources may lead to lower values of environmental services To restore the value of environmental services void water management is required to recycle void water as raw water that can be utilized by the community This study was conducted to determine the characteristics of community that use mine void water resources as a raw water estimate willingness to pay WTP community against the use of raw water obtained from the mine void water determine factors that affecting WTP society assessing the financial feasibility of utilization of mine void water as a raw water and freshwater aquaculture The study was conducted by gathering information through questionnaires in the Margahayu village involving 100 respondents Results of the study are the characteristics of the mine void water users showed 69 of respondents aged 41 60 years the majority of education level is graduated from junior high school as much as 33 with the income level of less than Rp 1 500 000 00 as much as 51 the amount of water needs ranged between 8 31 m3 month household The average value of WTP Rp 5620 00 per m3 which is influenced by education income and the amount of water needs Based on the financial analysis is obtained value of Net Present Value NPV of Rp 1 528 812 844 21 Net Benefit Cost Ratio Net B C by 2 56 IRR of 17 3 Mine void water utilization feasible and provide benefits to the community and is expected to governments and relevant parties in order to facilitate the development of the mine void water use and completeness through the ease of borrowing investment funds and other support needed , Mine void is a problem that abandoned mines after mining ends The loss of function of the mine void water as raw water resources may lead to lower values of environmental services To restore the value of environmental services void water management is required to recycle void water as raw water that can be utilized by the community This study was conducted to determine the characteristics of community that use mine void water resources as a raw water estimate willingness to pay WTP community against the use of raw water obtained from the mine void water determine factors that affecting WTP society assessing the financial feasibility of utilization of mine void water as a raw water and freshwater aquaculture The study was conducted by gathering information through questionnaires in the Margahayu village involving 100 respondents Results of the study are the characteristics of the mine void water users showed 69 of respondents aged 41 60 years the majority of education level is graduated from junior high school as much as 33 with the income level of less than Rp 1 500 000 00 as much as 51 the amount of water needs ranged between 8 31 m3 month household The average value of WTP Rp 5620 00 per m3 which is influenced by education income and the amount of water needs Based on the financial analysis is obtained value of Net Present Value NPV of Rp 1 528 812 844 21 Net Benefit Cost Ratio Net B C by 2 56 IRR of 17 3 Mine void water utilization feasible and provide benefits to the community and is expected to governments and relevant parties in order to facilitate the development of the mine void water use and completeness through the ease of borrowing investment funds and other support needed ]
