Proses ini akan difasilitasi menggunakan digital human modelling untuk mengidentifikasi kondisi awal dan untuk mensimulasikan improvement yang dilakukan. Hasil improvement dari rancangan workstation yang dibuat terbukti dapat menurunkan risiko WMSDs dengan penurunan nlai LBA sebesar 63-79%, OWAS dengan penurunan skor dari 2 ke 3, RULA dari 7 ke 2 dan 3, PEI dari nilai rata-rata lebih dari 2 ke nilai < ~1, dan skor REBA yang menurun ke 2 dan 3.
Indonesia's vision to become a developed country by 2045 places significant emphasis on infrastructure development as a primary directive. This infrastructure necessitates the deployment of supporting facilities such as hydrants, electrical panels, and others, in compliance with prevailing regulations. Sheet metal manufacturing companies play a crucial role in supplying these products. However, the workers in these companies are susceptible to work-related musculoskeletal disorders (WMSDs), which have detrimental effects on their well-being and ultimately impact the overall productivity of the organization. To address this issue, the present study aims to design workstations that mitigate the risk of WMSDs among workers, thereby improving their working postures. Employing a human-centered design methodology, the process commences with a factory assessment to evaluate the initial conditions, followed by ergonomic evaluations based on LBA, OWAS, RULA, PEI, and REBA analysis. Risk factors are identified, and design guidelines are established to reduce the existing risk levels. Digital human modeling is then utilized to identify the initial conditions and simulate the proposed improvements. The results demonstrate that the implemented workstation design improvements effectively reduce the risk of WMSDs. Specifically, the LBA scores decrease by 63-79%, OWAS scores transition from 2 to 3, RULA scores decrease from 7 to 2 and 3, PEI values reduce from an average above 2 to less than ~1, and REBA scores decrease to 2 and 3.
