<p>This study explores the influence of adaptive management indicators on consumer willingness to adapt to the single-use plastic (SUP) ban in Java Island, Indonesia, where the policy has been initiated but not yet fully implemented across all locations. Employing an Exploratory Factor Analysis (EFA) and logistic regression models, the research examines the impact of environmental responsibility, social and legislative influences, enforcement and compliance mechanisms, material preferences, personal guilt, and income levels on sustainable behavior. The findings highlight significant factors driving consumer adaptation, revealing the importance of enhancing environmental education, robust enforcement, social influence, and accessible eco-friendly alternatives. Environmental responsibility and satisfaction, external influences, and personal guilt were strong predictors of willingness to adapt, while income level was also a significant determinant. This study provides valuable insights for policymakers to design targeted strategies that foster public support and compliance with environmental policies, emphasizing the need for multifaceted approaches to promote sustainability and reduce plastic waste.</p>
