Environmental behavior is becoming increasingly important in maintaining environmental balance in society. Higher education is one educational institution that produces graduates with good knowledge in designing existing changes. This study aimed to determine the relationship between education, knowledge, involvement, and environmental behavior in waste management. This study involved 200 students who took courses in disaster and environmental education at the undergraduate level at Syiah Kuala University. Analysis of research data was carried out using SEM with the help of the AMOS application. This study reveals that in sustainable development, environmental education, environmental knowledge, and environmental involvement can predict student waste management behavior through campus programs. This finding also reveals that environmental involvement directly affects waste management and is a significant mediator variable that affects the relationship between environmental education and environmental knowledge. Thus, the study results imply that environmental education and knowledge lead to environmental involvement and environmental behavior of students in keeping the environment healthy and free from waste. The research implications can provide information to policymakers and programs related to a waste-free environment.
