Behavioral Intention Model for Waste Sortingamong Indonesian Urban Millennial Workers

This study explores how subjective norm, perceived behavioral control, and expectation influence waste sorting intention among urban millennial workers in Indonesia. Using data from 406 respondents, the study applied a quantitative survey analyzed with Structural Equation Modeling (SEM). The results show that perceived behavioral control affects expectation, which partially mediates its impact on intention. Both perceived behavioral control and expectation also directly influence intention, while subjective norm emerges as the strongest predictor, highlighting the role of social pressure in a collectivist culture. The findings suggest the need to strengthen social norms, enforce regulations, and improve infrastructure. Limitations include the focus on millennials, self-reported data, and a cross-sectional design. Future studies should target more diverse populations and track behavioral changes longitudinally.
