Purpose: This study aims to describe the adaptation and implementation of ecoprint techniques (pounding, steaming, fermentation) using local natural materials at Muhammadiyah Kepong Studio. It evaluates changes in students' attitudes and behaviors toward environmental awareness, responsibility, and cooperation after participating in ecoprint activities. The study also identifies character values—such as perseverance, discipline, tolerance, and creativity—internalized through these activities within the context of the "Clean and Fun School" movement. Methodology/approach: The implementation used a structured community service method involving a target area survey, preparation, scheduling, execution, and post-activity evaluation. Results/findings: Post-training assessments showed substantial improvement: knowledge of ecoprint techniques increased from 34% to 100%, local cultural knowledge from 57% to 100%, technical skills from 4% to 93%, and creative idea development from 5% to 97%. Character improvements were also notable, including responsibility and care (5% to 100%), collaboration (83% to 100%), perseverance and patience (63% to 100%), and environmental awareness (33% to 97%). Conclusions: Ecoprinting with natural materials instills environmental values and personal character traits, such as patience, thoroughness, and cooperation, promoting sustainable habits through experiential learning. Limitations: Findings are context-specific and may not generalize to other schools due to differences in student backgrounds, resources, and the implementation timeframes. Contribution: This study contributes to educational practices by integrating environmental art, character education, and sustainability, providing a model for similar programs in art education, environmental studies, and civic character development.
