Non-ergonomic sitting and writing positions can cause musculoskeletal disorders and reduce students’ learning concentration. Education on the importance of correct body posture during study is essential to be implemented from an early age. This community service activity aims to increase the awareness and understanding of elementary school students about the importance of applying ergonomic principles in proper sitting and writing positions during the learning process to support long-term health and comfort.
