Children’s education is an interesting concern for education activists, who are expected to become agents of change in the future. Environmental education for children will of course be a hope for the sustainability of environmental maintenance. Basic concepts of environmental maintenance need to be introduced to children’s education in schools with the potential of each region. The right methods and materials are needed for the effectiveness of environmental education for children. The purpose of this community service program is to increase children’s knowledge and awareness of the environment. Community service activities were carried out at the Indonesian School of Jeddah (SIJ) in January-February 2024. Participants in this community service activity were teachers and students. The implementation of community service activities was carried out through three activities, namely socialization activities and the application of environmental education modules for children, as well as hydroponic plant cultivation training as a form of environmental education for children. The results of the community service showed that there was an increase in teacher and student knowledge regarding the application of environmental education to children through learning modules. The application of environmental education modules was carried out through hydroponic plant cultivation practices, so as to improve the skills of teachers and students in environmental education. The level of satisfaction and assessment of community service activities through the application of environmental modules to children at SIJ is in the very satisfactory category.
