Abstract

Manual fertilization activities in dryland agriculture pose a high risk of musculoskeletal disorders due to awkward stooping postures and repetitive movements, as well as causing dose inaccuracies. This study aims to analyze ergonomic risks in manual fertilization using the Nordic Body Map (NBM) method as a basis for designing a portable soil injector. The evaluation was conducted on 30 active farmer respondents. The NBM analysis results revealed an average complaint score of 78.2, categorized as high risk, with dominant complaints reported in the right hand (5.3), upper back (5.1), left hand (5.0), right wrist (5.0), and left wrist (4.9). The continuous stooping position was proven to place significant physical stress on the upper body and spine. The implications of these findings confirm the urgent need for ergonomic intervention through the design of a portable soil injector based on Human Centered Design and user anthropometric data. The tool is engineered to eliminate stooping postures, reduce repetitive motions, and provide flexible fertilizer dose adjustments according to crop requirements, thereby reducing musculoskeletal injury risks and enhancing fertilization efficiency.
