| Summary: | Production worker’s job in manufacturing industries is one of the occupations that risk
to Musculoskeletal Symptoms (MSSs) such as awkward postures, repetition motion,
and forceful exertions which as causes to serious musculoskeletal injuries. The aim of
this study is to identify the prevalence of MSSs and Ergonomic Risk Factors (ERFs)
among production workers. This study was conducted using Nordic Musculoskeletal
Questionnaire (NMQ) as an interviewing method while Entire Body Risk Assessment
(ENBORA), Rapid Entire Body Assessment (REBA) and Quick Exposure Check
(QEC) as a direct observational tool. A total of 252 production workers from various
manufacturing industries were selected as samples in this case study. Mostly, the age
of production workers working there were between 21-30 years old with a percentage
of 62.7%. Based on the NMQ results, it showed that most of the workers dealt with
lower back (68.7%), shoulder (52.0%), upper back (51.6%) and hands/wrists (50.8%).
For QEC tool, all workers were found to have Moderate exposure level except for the
back region which for movement tasks with High exposure level (mean=31.18, SD =
6.604). Based on REBA tool, the risk factors on trunk and upper arm were most
experienced by workers which put the REBA risk level in High (mean=9.98, SD =
2.430) meanwhile for ENBORA tool, the production workers experienced Medium
exposure level mainly from hand/wrist. Pearson Chi Square test was conducted to
determine the correlation between NMQ variables and Ergonomic Risk Level. The
results indicated there was association between NMQ variables and Ergonomic Risk
Level. In conclusion, the high Ergonomic Risk Level among production workers has
significantly contributed to harmful exposure and developments of MSSs. Risk factors
such as awkward posture, task duration, repetitive motions and heavy physical work
must be avoided. The information from this study also suggested to use REBA tool as
best way to assess the level of an ergonomic risks at production in manufacturing
industries. |
