What Determines Community Willingness To Utilize Rainwater For Domestic Water Needs In Semiringkai, Timor Island?

Abstract

This study examines key factors influencing household willingness to utilise rainwater using a cross-sectional design and binary logistic regression. Data from 60 households were collected via structured questionnaires and interviews. The model achieved strong fit (deviance R² = 73.65%, AUC = 0.9756). Significant determinants include household income (β = -4.71, p = 0.012), knowledge of rainwater quality (β = 3.83, p = 0.048), infrastructure availability (β = -3.88, p = 0.036), and government support (β = -3.41, p = 0.040). Households with better knowledge are 46 times more likely to adopt rainwater, while lack of infrastructure and support lowers adoption. Findings highlight the need for financial incentives, infrastructure investment, and public education to enhance adoption. Future research should assess long-term policy impacts and advanced treatment feasibility.
