Evaluation of the Implementation of the Green Student Movement (GSM) Program by WALHI in the Governance of Plastic Use Reduction in Medan City

Background/purpose. The growing environmental issues in Medan City, particularly regarding plastic use and its detrimental effects, have prompted the Indonesian Forum for the Environment (WALHI) to launch the Green Student Movement (GSM) program. This program aims to raise awareness and involve youth in tackling environmental and humanitarian concerns.

Materials/methods. A descriptive qualitative approach was employed, utilizing data collection techniques such as in-depth interviews with WALHI and GSM organizers, direct observation, and documentation. The CIPP evaluation model (Context, Input, Process, Product), developed by Daniel L. Stufflebeam, was adopted to guide the evaluation.

Results. The findings indicate that GSM, as an environmental education program, has had a significant impact on students’ behavior, particularly in reducing plastic bag usage and promoting eco-friendly alternatives. Involvement in campaigns, training, and community-based activities has proven effective in raising ecological awareness. Despite challenges such as limited policy support and funding, GSM has contributed to the creation of a more environmentally conscious youth generation. The program’s focus on education and participation has been impactful, though its scope remains limited to educational institutions.

Conclusion. GSM has the potential to serve as a model for similar environmental education-based movements in other Indonesian cities. Strengthening institutional support, cross-sector collaboration, and expanding its reach beyond educational settings are essential for ensuring long-term success.
