Abstract

Abstrak
Ergonomik dan faktor persekitaran telah menjadi isu utama bagi industri perlombongan selama bertahuntahun, dan semakin meningkat. Dalam memastikan persekitaran kerja ergonomik, ianya memerlukan
perhatian khusus terutama dalam sektor industri ini. Disebabkan kekurangan pengetahuan ergonomik dan
kesedaran yang rendah di kalangan jurutera dalam industri perlombongan, maka ini menjadi isu utama di
Malaysia. Tujuan kajian ini adalah untuk menyiasat faktor risiko fizikal yang berkaitan dengan kerja-kerja
gangguan muskuloskeletal (WMSDs) dengan menggunakan Penilaian Ergonomik Tempat Kerja (WERA)
di kalangan pekerja industri perlombongan. Daripada penyiasatan itu, tahap tindakan daripada WERA
adalah medium yang menyatakan bahawa tugas-tugas perlu disiasat dengan lebih mendalam lagi dan
memerlukan perubahan. Semua faktor-faktor risiko fizikal melibatkan lima kawasan badan atasan seperti
bahu, pergelangan tangan, belakang, leher dan kaki yang telah dikenal pasti berkaitan dengan WMSDs
oleh penyelidik terdahulu. Terdapat lapan belas pekerja yang telah dipilih untuk terlibat dalam kajian
penyiasatan ini. Pekerja dipilih mengikut tugas pekerjaan mereka. Keputusan analisis yang diperolehi
akan digunakan untuk meningkatkan proses kerja, rekabentuk stesen kerja dan juga memperbaiki
postur kerja untuk meningkatkan tahap keselesaan pengendali. Kajian ini adalah penting bagi industri
perlombongan yang kekurangan maklumat dan penyelidikan mengenai isu-isu ergonomik dalam industri.
Dapatan secara keseluruhan menunjukkan bahawa keseluruhan proses tugas pekerjaan terpilih akan
menyumbang kepada gangguan muskuloskeletal sama ada pendedahan jangka masa yang singkat atau
panjang.

Abstract

The ergonomics and environment factors have been the main issue for the mining industry for many years,
and their profiles are increasing. To ensure an ergonomics work environment, it is possible to require
a particular attention especially in this industry sector. Due to lack of ergonomics knowledge and low
awareness among engineers in the mining industry, this may lead to become the central issue in Malaysia.
The aim of this study is to investigate the physical risk factor associated with work-related musculoskeletal
disorder (WMSDs) by using workplace ergonomics assessment (WERA) among workers in the mining
industry. Based on the investigation, the action level of the WERA is medium that stated that the tasks
need to be investigated further and it requires changes. All physical risk factors involved the five top body
regions such as shoulder, wrist, back, neck and leg. These have been identified to have an association
WMSDs by previous researchers. There were eighteen subjects selected in this investigation study. Those
subjects were chosen according to their job tasks. The results of the analysis were used to improve the
process of work, design of the workstation and also improving the work posture to enhance the comfort
level of operators. This study is crucial for the mining industry because there is a lack of information and
research about the ergonomics issues in the industry. The overall finding indicated that the whole process
of selected job tasks will contribute to musculoskeletal disorder either for a short or long time exposure.
