PERANCANGAN ALAT BANTU OPERATOR PADA PROSES PENCETAKAN BATAKO UNTUK MEMINIMASI RESIKO WMSDs (Work Musculoskeletal Disorders)

Abstract

Brick molding process is a job that requires human labor, this work is also done repeatedly for a long
time. The work that is done repeatedly for a long time poses a risk of WMSDs (Work Musculoskeletal
Disorders). The role of the facility and equipment ergonomic work is very important in this activity to minimize
the risk. TB. Sumber Rizki is an industry which is engaged in the printing of stone brick. In the production
process very dominant role of man as the work is done manually. This resulted in complaints of workers in some
parts of the body. Based on the results of the questionnaire NBM (Nordic Body Map) contained the biggest
complaints in the back, arms, shoulders, and the right hand workers. Material mixing process is a process that
requires the operator bent almost 90 degrees, which is considered state of the posture of the health problems
that can lead to musculoskeletal disorders. Based on observations using the QEC (Quick Exposure Checklist),
obtained exposure value for the stirring process material that is equal to 53.41% where the necessary action in
the near future. Therefore perform the design of the stirring bath aids, materials and work desk operators to
minimize the risk of WMSDs using anthropometric data. Once the design is done, the exposure value decreased
to 44.31%.
