Manufacture is one of the industry that has the risk of musculoskeletal disorders. The aim of this research is to analysize the risk factors from the symptoms of disorders of musculoskeletal. This research conducted on March until April 2018 by involving 51 workers on Mixing area and 40 workers on Office Area of X Corporation which is a manufacturing company who made the component of the motor vehicle. This research used Cross Sectional method by using QEC questionnaire and combination of psychosocial questionnaire as the instrument for data collection. The independent variable of this research are the characteristic of workers (age, gender, body mass index, smokimg status, and working time), physical factors on the work place (force, awkward postures, repetitive motion, and coupling) and psychosocial factors (job demands, control of the job, social support, skill discretion, job satisfaction, and work stress). The result of this research shows there is a significant correlation of body mass index with a symptoms on the top of the back, working time and skill direstion with a symptoms of the wrist, high risk of physical factor with a symptom of the neck, and work stress with a symptom of shoulders and the low part of the back. Therefore it needs to be a further control about ergonomic factor at X Corporation.

Manufacturing is one of the sectors that has a high risk of musculoskeletal disorder. Manufacturing workers are associated with high physical workloads and spend most of their work time with standing or sitting. The aim of this research is to analyze individual characteristics, physical factors, and psychosocial factors of musculoskeletal disorder. This research was conducted in March-July 2020 involving 94 workers with 68 field workers and 26 office workers. The design used in this study was cross sectional with NMQ, QEC, and a combination of psychosocial questionnaires from JCQ, COPSOOQ, and ERI. The independent variables in this research are individual characteristics, physical factors, and psychosocial factors. The dependent variable of this research is musculoskeletal disorder symptoms. The results of individual characteristics found a significant relationship between the type of work with musculoskeletal disorder symptoms on the hands or wrists. The results of physical risk factors found a significant relationship between moderate, high, and very high risk with musculoskeletal disorder symptoms on the hands or wrists and upper back. Whereas for psychosocial factors found a significant relationship between high work demands and moderate high work stress with musculoskeletal disorder symptoms on shoulders, neck, and upper back. Therefore, we need control and intervention to reduce the risk of musculoskeletal disorder symptoms.

Cashiers are at risk to develop musculoskeletal disorders. The purpose of this research is to identify risk factors of musculoskeletal symptoms. The design of this research is cross-sectional. Data was collected with QEC, combination of psychosocial questionnaire, NMQ, meter tools, and lux meter. Results showed that the highest musculoskeletal symptoms prevalence was found in shoulder and there are significant association between: gender and shoulder (OR: 3.575) & ankle (OR: 2.784) symptoms, job satisfaction and low back symptoms (OR: 3.059), effort and low back symptoms (OR: 7.650). Based on results, it is recommended to adjust workstation based on anthropometry data.

Hasil penelitian pada faktor risiko individu menunjukkan adanya hubungan signifikan antara jenis pekerjaan dan status merokok dengan gejala gangguan otot rangka pada punggung bawah, serta adanya hubungan yang signifikan antara jenis pekerjaan, indeks massa tubuh dan status merokok dengan gejala gangguan otot rangka pada lutut.
Hasil penelitian pada faktor risiko fisik ditemukannya hubungan yang signifikan pada faktor risiko sangat tinggi pada punggung dan bahu dengan gejala gangguan otot rangka pada punggung, serta faktor risiko tinggi dan sangat tinggi pada bahu dengan gejala gangguan otot rangka pada lutut. Sedangkan untuk faktor psikososial tidak ditemukannya hubungan yang signifikan dengan gangguan otot rangka. Oleh karena itu diperlukannya pengendalian dan intervensi lebih lanjut khususnya untuk faktor risiko fisik.

Construction workers are at risk to develop musculoskeletal disorders. The purpose ofthis research is to analyze risk factors of musculoskeletal symptomps in constructionworkers. The research was conducted in March-April 2018 involving 156 workers. Thedesign of this research is cross-sectional. Data was collected with QEC, combination ofpsychosocial questionnaire, NMQ, lux meter, and WBGT. The results show that thereare significant association between the individual factors (type of work and smoking)with the musculoskeletal symptomps. The level of risk associated with muskeletalsymptoms are high and very high risk level. While the the psychosocial factorsassociated with musculoskeletal symptoms are high job demands and low co-workerssupport. Therefore it is necessary to make changes and interventions to reduce the riskmusculoskeletal disorder through some control, especially physical and psychosocialfactors.

Many workers in the manufacturing industry report MSD complaints. This study aims to determine the prevalence of MSD complaints and the relationship of physical, psychosocial and individual factors to MSD complaints at PT NI in 2020. The method used was quantitative with a cross sectional study design. A validated standardized questionnaire was distributed to 120 respondents. Data analysis used is SPSS with logistic regression models to identify risk factors for MSD complaints and their consequences. The prevalence of MSD complaints in the last 12 months, reduced activity and MSD complaints in the last 7 days were 78%, 43% and 54%. Physical factors related to MSD complaints are trunk bending position with a proportion of ≤ 50% of time, repetitive work with a proportion of> 50% of time, kneeling / squatting with a proportion of> 50% of time, body vibration ≤ 50% of time, and sitting position> 50% of time . For psychosocial factors are work dissatisfaction, high over commitment, high work pace, and moderate work stress. While the individual factors are the status of contract workers, tenure, 2 shift work systems, and female employees. In conclusion, workers at PT NI have a high prevalence of MSD complaints and their consequences for various parts of the body. A planned and measurable effort is needed to eliminate the risk factors for MSD complaints.
