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.

Abstract

Tujuan penelitian ini adalah merancang aerator yang digerakkan oleh energi surya dan berbasis Internet of Things (IoT) menggunakan pendekatan Value Engineering (VE). Penelitian menggunakan metode Value Engineering dengan tahapan informasi, analisis fungsi, kreativitas, evaluasi, dan pengembangan. Hasil penelitian menunjukkan desain aerator tenaga surya memiliki biaya pembuatan yang lebih murah dibandingkan aerator konvensional. Pengembangan aerator tambak menggunakan motor listrik satu fase yang dipadukan dengan panel surya 20 Wp. Biaya pembuatan aerator tenaga surya sebesar Rp4.413.600, sedangkan aerator konvensional sebesar Rp5.500.000, sehingga terdapat penghematan sekitar 19,8%. Penelitian ini berdampak positif terhadap pengelolaan tambak, efisiensi biaya, dan peningkatan kesejahteraan petambak. Aerator cerdas berbasis IoT dan tenaga surya dengan pendekatan Value Engineering terbukti lebih efisien, ramah lingkungan, dan adaptif terhadap kondisi air tambak dibandingkan sistem konvensional. Inovasi ini berpotensi menjadi solusi berkelanjutan dalam peningkatan budidaya perikanan di Indonesia.
