Bridging the Youth Development Index and SDG 8: East Java’s Strategy for Sustainable Youth Development

This study aims to build and test a structural equation model to measure the contribution of waqf facilities to the realization of waqf benefits in Islamic educational institutions. Using the Resource-Based View and Stakeholder Theory as a foundation, this research proposes that waqf facilities, as strategic resources, have a positive and significant influence on multi-dimensional waqf benefits. The research method uses a quantitative approach with an explanatory survey, applying Structural Equation Modeling - Partial Least Squares (SEM-PLS). Data was collected through questionnaires from Nazhir and Islamic boarding school administrators with purposive sampling of 100 respondents. The analysis results show that the measurement model is valid and reliable (Cronbach's Alpha > 0.70, AVE > 0.50). The structural model testing reveals that Waqf Facilities significantly influence Waqf Benefits with an R-square value of 0.415 and a large effect size (f-square = 0.708), thus hypothesis H1 is accepted. The novelty of this research lies in its methodological contribution by positioning SEM-PLS as a diagnostic tool for nazhir, its theoretical contribution in enriching the application of RBV in religious non-profit contexts, and its practical contribution in providing an empirical evaluation model to optimize evidence-based and impact-oriented waqf management
