This study aims to develop Word wall-assisted Student Worksheets (LKPD) for fifth-grade students in Class V-B on the topic of harmony in ecosystems at SDN 029 Tarakan. This study also aims to determine the feasibility of the developed LKPD by validating it with media and subject matter experts. Furthermore, this study aims to determine students' level of interest in the LKPD using a student response questionnaire. This study used a research and development approach, applying the ADDIE model, which consists of five stages: Analyze, Design, Develop, Implement, and Evaluate. The data collection techniques used included observation, interviews, validation sheets, student response questionnaires, and documentation. The validation results show that the assessment by media experts achieved a 95% score, which is classified as feasible. The subject matter expert validation results show a 91.4% rating as very feasible, while limited and field trials obtained 85% and 86%, respectively, as very interesting. Based on this data, the Word wall-assisted LKPD for fifth-grade students in class V-B on the topic of Harmony in the Ecosystem at SDN 029 Tarakan is deemed highly feasible and interesting for use in learning.
