Ergonomics study among operators in water-jet production area in aircraft industry

2020 , W.N.F. W. Mahmod , Ummi Noor Nazahiah Abdullah , Norashiken Othman

This paper is to conduct the ergonomics risks assessment (ERA) among the operators in water-jet production workstation area in aircraft industry, working with aircraft panels’ liners named Oriented Strand Board (OSB) and the aircraft panels which require forceful exertion, lifting and carrying task in order to complete the operation activity. The possibility of Work Musculoskeletal Disorders (WMSDs) among operators could occur due to their daily working activities. The objectives of this study are to conduct the initial ERA and advance ERA among the waterjet production operators. Twelve male operators had been participated in this study with range age 20 to 40 years old. Nordic checklist, operational interviews, observations, Rapid Entire Body Assessment (REBA) tool and Manual Handling Assessment Chart (MAC) tool as part of advance ERA evaluation were applied in this study. The initial ERA results recommend for further investigation on awkward posture and forceful exertion among the operators in waterjet production. The results from REBA shows that all operators obtain high risk ergonomics score i.e. 10 scores for load weight and high repetitive in lifting and carrying task. The results from MAC validate that gripping mechanism during lifting and carrying activity requires ergonomics intervention for reducing the forceful exertion and high repetitive risk. The results from ERA, REBA and MAC assessment in this study are novel contribution in the aircraft production since the similar data is not exist yet. The results will be translated into measurable design parameters for waterjet workstation improvement in future design workstation.

Ergonomics issues among operators in composite manual hand layup activities: a systematic literature review

2023 , M. Zulhaimi Yusof , Ummi Noor Nazahiah Abdullah , Muhamad Nasir Murad

Two laying techniques are used for composite manufacturing. They are done automatically and hand layup manually. These two laying techniques are used widely in the world. In Malaysia, the manual hand layup is more preferable in producing the secondary structures due to it being a cost-effective and efficient technique. However, it puts the operators at risk and may lead to musculoskeletal disorders. Previously, the management of one composite manufacturing company received complaints from the operators regarding musculoskeletal disorders. This paper aims to get the ideas of the potential for future ergonomics studies on the manual hand layup in composite manufacturing. A systematic literature review has been applied in this study. The main results show that there have not been many kinds of ergonomics studies in this field. Only six previous related studies were found in the past six years recently. In future works, it is suggested that more ergonomics studies are needed to be conducted in composite manufacturing. The information gathered may be helpful for employers to take action to prevent their operators from getting musculoskeletal disorders. In addition, future researchers may extend the existing findings from previous studies.

Critical success factors of service learning in tertiary education: challenge of online learning approach in ergonomics product design course

2022 , Norashiken Othman , Ummi Noor Nazahiah Abdullah

This study intent to investigate critical success factors of implementing online learning approach in ergonomics product design course embedding SULAM Project during COVID-19 pandemic. The first objectives are to interrogate suitable teaching approach implemented for PDET. Next is to assess students' satisfaction with the course in comparison to their grades after SULAM was embedded in SULAM in PBL component, as well as the impact of the pandemic on satisfaction levels. The third aims are to evaluate student perceived and experiences, as well as to discover relevant student recommendations that may be integrated into the next course offering. To achieve the study aims, a systematic literature review was conducted to investigate the current teaching and learning implementation in PDET course. OMR Forms and User Experience Questionnaire (UEQ) were distributed to access students’ satisfaction and perceive experiencing in online learning approach. As a results, the course has been identified commonly deploys an inclusive design approach and integrating an interdisciplinary approach. However online learning and team cognition approach has been a significant change during COVID- 19 pandemic outbreak. This study extends significantly to the preparation of teaching and assessment techniques for future students, especially in unpredictable conditions such as pandemic and endemic scenarios, when lectures and students confronting various problems.
