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.
