Implementing the OBE Model in Plastic Waste Management Using the 4R EPR Pattern for Green Campus

For quite some time, Universitas Negeri Malang (UM) has paid much attention to waste management due to the rapidly increasing waste generated by campus activities, including from the offices, classes, canteens, and major events held by the university.The waste has caused issues related to environmental cleanliness and aesthetics.This research aims to 1) understand plastic waste management on the UM campus using the 4R pattern: reduce, reuse, recycle, and replace; 2) understand efforts to optimize plastic waste management on the campus through Extended Producer Responsibility (EPR); and 3) implement the OBE model with the 4R EPR pattern at UM to support the green campus initiative.This research used a mixed-method approach, combining quantitative and qualitative descriptive methods.Data were collected through observation, interviews, documentation, and actions related to plastic waste management on the UM campus.Results show that plastic waste management on the UM campus, using the 4R (reduce, reuse, recycle, and replace) pattern, has been conducted in collaboration with leaders, lecturers, groundskeepers, and students.Efforts to optimize plastic waste management through Extended Producer Responsibility (EPR) were carried out in partnership with the Malang City Waste Bank and PT Zerolim, two parties that strictly sorted waste according to type so that the waste sold could get a high price.Implementing the OBE model with the 4R EPR pattern at UM was carried out to support a Green Campus to show UM's support for environmental sustainability.In the future, UM students can play a more active role in reducing plastic waste, such as recycling, producing creative goods from plastic waste, or developing more efficient plastic waste processing technology to support the Green Campus.
