Abstract : The effect of an ergonomic pineapple harvesting basket on muscle activity was compared with a traditional rattan basket in this study. In harvesting tasks, muscle activity was measured over 5-, 10-, and 15-minutes using surface electromyography (sEMG) on the Latissimus Dorsi muscle. The results indicated that muscle activity was significantly lower in the ergonomic basket across all durations (p < 0.001) and thus able to reduce strain and prevent musculoskeletal risks. Overall, these results highlight the practical benefits of ergonomic interventions in agriculture to increase worker safety, decrease fatigue, and increase productivity in the pineapple harvesting industry.
