This research aims to analyze the factors influencing the decision to engage in a cash waqf in West Nusa Tenggara. This research method employed a quantitative approach with an associative framework. This study did not specify the population size. Accordingly, sampling was performed using a non-probability sampling method, which ultimately resulted in a convenience sample of 230 respondents, as determined by the Lemeshow formula. Religiosity, attitude, and subjective norm are the independent variables, while the decision to cash a waqf is the dependent variable. Awareness and interest serve as a moderating variable. This study utilizes Structural Equation Modeling – Partial Least Squares (SEM-PLS) to analyze data. The research results indicate that religiosity, attitudes, and subjective norms have a positive but insignificant effect on the decision to cash a waqf. The same result occurs when religiosity, attitudes, and subjective norms are mediated by awareness. However, these three variables positively impact the decision to cash a waqf, with interest as a mediator, and this impact is statistically significant. An adjusted R-Squared value of 0.520 or 52 percent indicated that the variables of religiosity, attitudes, subjective norms, awareness, and interest can explain the variation in the decision to cash waqf, which indicates a moderate model. This result is strong in the context of complex behavioral models, given that many similar studies show Adjusted R-Squared values between 30 and 70 percent.
