Energy demand and waste production are inevitable issues that happened globally, including in Indonesia. Population and economic level growth increase the national energy demand and municipal solid waste production. On the other hand, the Indonesian government set a target to achieve 23% renewable energy development by the year of 2025. Waste to energy program through the implementation of Sustainable Modular Bioreactor Landfill Gas Plant, is considered to be a powerful solution in solving the problem of energy supply and waste production. Since the costs of bioreactor are not cheap, funding becomes an emerging problem. Both public and private sectors are considered unable to finance the implementation of this technology. In the public sector there are frequent conflicts of interest, whereas in the private sector, funding of such investment is deemed less attractive in terms of profit gained. Participatory funding system called resident-based financial model is used to cope this emerging problem. This funding system will be implemented in several cities whose waste management system is considered worrying. The purpose of this study is to explore the demographic factors that encourage people to participate in resident-based financial model. Method used to collect the primary data is random sampling through direct interview and/or online questionnaire, while logistic regression method is used to determine which demographic factors encourage society participation. The result of this study shows that income is the only variable that significantly influences society participation in funding bioreactor.
