Analysis and Waste Management Planning at Universitas Sulawesi Barat Based on the Green Campus Concept

Abstract

Background: The increasing number of students and academic activities at Universitas Sulawesi Barat (Unsulbar) has led to higher waste generation on campus. However, waste management at Unsulbar has not yet been supported by an integrated, systematic, and sustainable system aligned with Green Campus principles. Objectives: This study aimed to assess the existing condition of waste management at Unsulbar and to formulate strategic recommendations for improving campus waste management based on the Green Campus concept. Methods: A descriptive-exploratory design was employed using the Plan–Do–Check–Act (PDCA) framework. The study was conducted in five faculties over eight observation days. Data were collected through direct field observation, daily waste weighing, waste composition identification, interviews with cleaning staff, and assessment of waste management indicators based on UI GreenMetric criteria. Results: The findings showed that the average waste generation at Unsulbar was 0.229 kg/person/day, with plastic and paper/cardboard identified as the dominant waste components. The evaluation also revealed that campus waste management performance remains low, particularly in waste segregation, recycling programs, organic and inorganic waste treatment, and institutional policy support. Conclusion: Unsulbar needs to strengthen its waste management system through a 3R-based strategy, including faculty-based waste segregation, establishment of a campus waste bank, integrated composting, Zero Waste Campus campaigns, digital waste monitoring, and formal university-level waste management policies. These strategies are expected to support Unsulbar’s transition toward a sustainable Green Campus and improve its future performance in the UI GreenMetric assessment. Novelty/Originality: This study provides an initial campus-based waste management assessment at Unsulbar using the PDCA framework and UI GreenMetric indicators, offering practical strategic recommendations for developing a sustainable Green Campus waste management model.
