A clean, green, and comfortable school environment is one of the factors that supports a conducive learning process. However, limited land often becomes an obstacle in developing green spaces in schools. This situation led to the implementation of the Happy Wall Garden program at UPT SD Negeri Ngadirenggo 01 as an effort to optimize space through the integration of mural art and recycling-based greening. The program aims to create a more fresh, aesthetic, and educational learning environment while also fostering awareness of environmental preservation. The method used is a participatory approach through stages of observation, coordination with the school, planning, mural implementation, creating a wall garden using used plastic bottles as planting media, and evaluating the results. The program's implementation shows that integrating murals and wall gardens can transform school wall areas that were previously underutilized becoming a more interesting and educational space. Using used plastic bottles as planting media also provides a simple example of applying recycling principles in everyday life. Besides beautifying the school environment, this program strengthens collaboration between students and the school in creating a more comfortable learning space
