Peningkatan Pengetahuan Pencegahan Low Back Pain melalui Edukasi Ergonomi Berbasis Diagnosis Komunitas pada Pekerja UMKM Tahu dan Tempe di Kota Mataram

Abstract

Low back pain (LBP) is a common occupational health problem among informal sector workers, including workers in home-based small-scale tofu and tempe industries, due to repetitive manual activities and non-ergonomic working postures. This community service program aimed to improve workers’ knowledge of LBP prevention through occupational health education developed from a community diagnosis approach. The program involved 36 workers from a tofu and tempe small-scale industry in Kekalik Kijang, Mataram City, Indonesia. Community diagnosis was conducted through field observation, review of secondary health center data, participatory discussions, and a Knowledge, Attitude, and Practice (KAP) survey to identify determinants of risky work behaviors. The intervention consisted of door-to-door education using posters and demonstrations on ergonomic working posture, safe manual handling techniques, and simple stretching exercises. Short-term outcomes were evaluated using pre- and post-tests of knowledge. The results showed a clear shift in knowledge distribution from low–moderate levels at pre-test to predominantly high levels after the intervention. These findings indicate that community diagnosis-based occupational health education can effectively improve workers’ knowledge of LBP prevention in small-scale home industries.
