This study aims to analyze approprietness of work posture, work equipment, and workstationthat cause the symptoms of MSDs complaints of computer users Head Office PT X. Designstudy is cross sectional. All of the data collected in these study are derived from primary data ofobservation results in the form of workm posture, work equipment, and workstation. The resultsstudy showed there were discrepancies in some of work posture while work, work equipmentused, and workstation. The results of the symptoms MSDs complaints use ROSA methodsshowed variying results, that are the ROSA final score 1-4 (further assessment not immediatelyrequired) and 5-10 (further assessment required as soon as possible). The observation resluts ofthe symptoms MSDs complaints showed 92 (87%) of respondents feel there are complaints atone area of the body. Many areas of the body most complaints are upper neck (67%), lumbar(62%), and lower neck (53%). It is recommended to make adjustments of work equipment byworkers, doing stretching on the side lines job, and socialization importance of ergonomics toworkers.

In the era of the industrial revolution 4.0, humans still being an important role in production in several sectors. But humans also have limitations in terms of physical, physiological, and psychological. This imbalance can cause a problem in the body, namely work musculoskeletal disorders (WMSDS). The purpose of this study was to analyze individual, occupational, and psychosocial factors on WMSDS in workers in the packing area of PT AS. This type of research is cross-sectional with 172 workers in the packing area of PT AS. In ergonomics risk assessment, administrators/supervisors use ROSA, packing operators use RULA, helpers use OWAS. The results of questionnaire showed that the highest prevalence at 7-days WMSDS were neck, shoulder and upper back, while at 12 months, the highest prevalence were neck and shoulder. The analysis of this study found that there was a relationship between 7-days WMSDS with a stooping attitude for 1-4 hours with an OR value of 2.07 (1.00-4.32), the frequency of carrying loads 21-30 times/hour with an OR value of 8.33 (1.13-61.50) and mild level of stress with an OR value of 2.48 (1.10-5.59). Meanwhile, at 12 months of WMSDS, high work demands have a significant relationship with WMSDS in packing area workers of PT AS with an OR value of 2.67 (1.19-5.99). complaints of WMSDS in the packing area of PT AS are quite high (>60%), so it is necessary to repair it immediately
Scaffolding is an inseparable part of a construction work. Scaffolding work contributes to the emergence of risk factors for skeletal muscle disorders due to work (gotrak) or musculoskeletal disorders (MSDs). The purpose of this study was to analyze the risk factors for the occurrence of scaffolding at PT X. This type of research was crosssectional with 156 employees as respondents at PT X. Ergonomics risk factor assessment in the workplace is carried out with an approach to assessing the level of occupational risk and subjective complaints of workers. Respondents provided information on individual characteristics, ergonomic risks using the method (Rapid Entire Body Assessment or REBA) with the results achieving high and very high scores. The level of ergonomics risk shows that 66.23% of respondents are in the high risk category and 33.77% of the respondents are in the low risk category. The analysis of cough complaints on workers using the Nordic Body Map questionnaire resulted in the 3 highest complaints, namely neck, shoulders and hands/wrist. This study shows that the risk factors for the occurrence of Gotrak scaffold workers at PT X at 12 months old are age 30 years OR 1.91 (95% CI 1.37-3.25), working period 10 years OR 2.42 (95 % CI 1.39-4.19), awkward posture OR 6.24 (95% CI 2.40-16.21). While the risk factors for gotrak that caused the absence of the last 12 months are age 30 years OR 1.32 (95% CI 1.18-1.76), years of service ≥ 10 years OR 1.65 (95% CI 1.03-2.65), type of work OR 10.98 (95% CI 4.2628.26), REBA score 2.53 (1.78-3.00), demands at work OR 1.65 (95% CI 1.02-2.51), work organization and job contents OR1.44 (95% CI 1.28-2.93, for risk factors for the last 7 days, namely type of work OR 2.79 (95% CI 1.28-6.07), health and wellbeingOR 1.43 (95% CI 1.09-1.84).
As a workplace, office environments have significant hazards and risks associated with the interactions between human and computer. The consequences that may arise are related with the healthy state of worker, direct and indirect financial impact, and company productivity impact. In order to protect the workers, company assets and facilities; a comprehensive office ergonomics program is required to manage the risk factors of musculoskeletal disorders. As a start, necessary measures are required to improve the knowledge and perceptions of workers in the aspects of office ergonomics. Knowledge and perception are the foundation to achieve healthy behavioral changes. The healthy behavioral change is required for workers to control the risk factors of musculoskeletal disorders. Education, in the form of training, acts as one of critical factors to increase knowledge and perception. This study is performed to analyze the effect of office ergonomics training intervention on the knowledge and perception of office workers at PT XYZ. Quasi-experimental research was selected by involving both, the intervention and comparison groups. Two treatments were given to the intervention group, they are self-learning type intervention and online office ergonomics training intervention. Only one treatment was given to the comparison group, the self-learning intervention. Based on the research, it is concluded that the online office ergonomics training increased the knowledge and overall perceptions of the office workers of PT XYZ. Online office ergonomics training gave a more significant influence than the self-learning type intervention.
