Greening Program as a Green Campus Strategy to Support SDG 12 (Responsible, Consumption, and Production) and Foster Environmental Care Attitudes Among Undergraduate Biology Students

This study evaluates the effectiveness of a participatory greening program in implementing a Green Campus and achieving SDG 12 among Biology students. A quantitative pre-experimental, one-group pre-test post-test design was employed with 80 undergraduate student selected by purposive sampling. Instruments included expert-validated knowledge tests, environmental questionnaires, and observation checklist (instrumental validity score of 100%). The four-month program involved activities such as planting, watering, weeding, fertilizing, and monitoring, specially designed to promote sustainable consumption and production practice-including organic fertilization efficient water usage, composting, and responsible resources management. Student participation averaged 84.15%. Statistical analysis using the Wilcoxon signed-rank test indicated a significant increase in environmental knowledge (Z = -7.786, p < 0.001) with a high N-gain score of 0.83. Additionally, students’ environmental care attitude improved significantly, with the mean score rising from 51.37 to 91.81, categorized as “very positive”. These findings demonstrate that the greening program is empirically effective in improving ecological literacy and foresting proenvironmental attitude while reinforcing sustainable production principles. Therefore, this program can be adopted as a scalable and sustainable model for Green Campus initiative in higher education.
