Analisis Ergonomi pada Operator Mesin Pemisah Biji Semangka

Abstract

Watermelon is a fruit commodity that has high prospects for development. The provision of seedless watermelon seeds which is still done manually takes a long time and requires a lot of energy. One alternative to increase the productivity of seedless watermelon is to make a watermelon seed separator machine. In this case, the study of the ergonomic aspects of the watermelon seed separator machine includes assessment of body posture, assessment of muscle complaints in the body and the tendency of aspects of ease, safety and comfort of operators in using the watermelon seed separator machine. The research methods used include data collection through observation, questionnaires and ergonomic measurements using the RULA (Rapid Upper Limb Assessment) method, Nordic Body Map (NBM) and tendency test. Respondents in this study were watermelon seed separator machine operators. The results of the assessment using RULA to assess body posture obtained a score of 4 which requires improvement if necessary. The results of the operator's assessment using NBM had an average value of 48.3 which did not require improvement. The results of the tendency test on the aspects of ease, safety and comfort obtained the highest good value. Analysis using RULA, NBM and trend test methods is needed to identify and evaluate watermelon seed separator machines in terms of ergonomics on the operator's posture, so that it can minimize complaints of work-related diseases in the short and long term for farmers. and analyze the tendency of operators to use watermelon seed separator machines.
