The present study aims to investigate the impact of community service based on environmental education on increasing environmental awareness among Indonesian youth. The present study employed a descriptive quantitative approach, utilising a pre-experimental design of a single group, pretest-posttest type. These coding techniques were employed to identify narrative patterns, group dynamics and the supporting and inhibiting factors that emerged during the learning process. The descriptive analysis demonstrated a significant increase in all indicators of environmental awareness following the implementation of the community service-based education programme, including participants' knowledge, attitudes, behaviours, and self-efficacy. Furthermore, a significant increase in attitudes was observed, from an initial score of 68.2 to a post-intervention score of 86.7. These results underscore the significance of programme design that integrates critical learning theory, transformative approaches, and community participation in fostering a generation that is aware of, concerned about, and actively engaged in environmental sustainability. It is hoped that this initiative will set a precedent for sustainable community service and make a meaningful contribution to the development of a future-oriented environmental agenda.
