This developmental study aims to design an educational media tool with the named SAREHAT application as an effort to enhance students' comprehension of body health topics in fifth-grade elementary school, which is motivated by students' low comprehension of body health. This study employs the Research and Development (R&D) methodology with the ADDIE instructional design approach, which consists of the following stages: Analysis, Design, Development, Implementation, and Evaluation. The research population includes 36 students and teachers from the fifth-grade class at SDN Tanjunglaya 02, as well as 2 teachers and 3 experts. Data was collected using techniques such as interviews, validation forms, student response questions, and comprehension tests. The results of the study prove that the SAREHAT application as an educational media is feasible and successful in improving students' comprehension of body health topics and has received positive responses from students. Thus, the SAREHAT application can raise students' consciousness of the importance of protecting body health, which can foster healthy lifestyle comportments from an early age.
