Summary:
Environmental education based on Education for Sustainable Development (ESD) demands a contextual, participatory, and action-oriented learning approach. This study aims to describe the implementation of the ESD-based Green Product Challenge Campaign through kamishibai media integrated with the Science Project learning in Vocational High Schools. The study uses a qualitative descriptive approach with a reflective practice design, involving grade X students across majors in a series of activities that include ESD socialization, kamishibai media development, and presentations at the peak of the environmental campaign. The results of the study indicate that the kamishibai-based campaign is able to improve students' understanding of waste management, foster environmental awareness, and develop psychomotor and social skills through project-based learning. Kamishibai acts as a visual storytelling medium that helps students connect science concepts with real environmental problems in schools. In addition to being a learning medium, kamishibai functions effectively as a school-based environmental campaign medium that supports the implementation of ESD. This study concludes that kamishibai media has the potential to be an alternative pedagogical medium in implementing ESD-oriented project-based learning in vocational secondary education and contributes to the achievement of SDGs 8, SDG 12, and SDG 13.
