Reduksi Keluhan Muskuloskeletal Pekerja dan Waktu Siklus Prses Produksi Berbasis Ergonomi Pada Insdustri Karet

Abstract

Achievement of plant capacity and reducing bottlenecks in the production process at wet blanket
workstation determined on the level worker of musculoskeletal disorders and the cycles time of the production
process per slabs. Capabilities and limitations of workers, equipment, task, and environmental organizations
must be harmonized for level of workers musculoskeletal disorders and the cycles time of the production
process per slabs reduction. The problem scale priority based on total ergonomics must be applied early with
identification of 8 aspects of ergonomics, planned and considered systemic, holistic, interdisciplinary and
participatory and apply the concept of appropriate technology become one of problem solution about this case.
Reduction of level of worker musculoskeletal disorders and cycles time of the production process per slabs
based on ergonomics; include redesigning of the ergonomics table and standing-seat chair folding work wet
blanket, setting the pattern system of pair work, giving an active break, providing additional nutrition in
the form of sweet tea and snack pempek, provision of personal protective equipment, and redesigning of the
physical work environment. Experimental research was using the treatment by subject design, with involved
17 workers samples who perform activities on the conditions of activity before and after the redesign based
on ergonomics. The level worker of muskuluskeletal disorders, and the cycle time of the production process
per slabs data were analyzed using Two Pair Sample t-test at a significance level of 5%. The results of study
showed that after redesign of wet blanket workstation based on ergonomics there was a significant reduction
of the level worker of muskuluskeletal disorders as 21.02%, and reduction of the cycles time of the production
process per slabs as 21.85%.
