<![CDATA[Environmental awareness among elementary students is essential for fostering sustainable behaviors from an early age. This study aimed to investigate the effectiveness of local wisdom-based e-module on ecosystem concepts in enhancing environmental awareness among fifth-grade students. The research was conducted at a private elementary school in Bogor, Indonesia, involving 30 students through a quasi-experimental design with a one-group pretest-posttest model. The developed e-module integrated traditional ecological knowledge and local cultural values from the Bogor community, such as nature conservation, the sustainable use of resources, and ecosystem preservation. Results revealed a significant improvement in students’ environmental awareness, with an average pretest score of 52 and a posttest score of 58 out of a maximum of 64. The normalized gain (N-Gain) was 0.55, indicating a moderate level of effectiveness. Among six measured indicators, the highest gain was observed in “appreciating nature and ecosystems” (N-Gain = 0.73), while the lowest was in “participating in conservation efforts” (N-Gain = 0.20). These findings highlight the potential of integrating local wisdom into digital learning materials to strengthen character education and environmental values in primary education. Future research is recommended to incorporate community-based conservation activities for more comprehensive learning outcomes.]]>
