Introduction:Laboratory is a means of improving the effectiveness of learning. The problem faced by laboratory staff in performing their work (analysis and experimentation) is fatigue caused by long work time with inappropriate sitting posture and position. The use of a wooden chair without a backrest and with a seat height that is too high or too low can cause musculoskeletal disorders (MSDs). This study aims to provide a workstation design suggestion with attention to ergonomics to reduce complaints of musculoskeletal disorders. Method: This descriptive research used an observational method. The population in this research consisted of 31 female students of a feed laboratory user, and the sample consisted of 16 respondents at the SIKIA Laboratory. Data collection for this study was conducted from July to September 2022. The independent variable in this study was the dimension of the workstation, and the dependent variable was musculoskeletal complaints. Result: Anthropometric measurements on laboratory assistants of the SIKIA Laboratory showed that the average popliteal height was 53.25 cm. Assessment on musculoskeletal disorder complaints shows that most complaints are found on “Pain in the back” with a score of 36. A new chair and table design is proposed, where the width of the seat back is 39.75 cm. Conclusion: A new workstation design is proposed that focuses on ergonomics to reduce the complaints of musculoskeletal disorders.

Introduction: Organizational success is influenced by the performance of each employee in it. Work stress experienced by the employees is one of the obstacles in improving the quality of the organization. Another research showed that employees of Manado City Health Office experienced 27.7% low stress and 72.3% moderate stress, which affected the work productivity of the employees. This research aims to see the relationship between gender and exercise habits on the stress experienced by the employees of Surabaya City Health Office. Method: This research is an observational type of research where the primary data were obtained from the responses of 32 employees of the Surabaya City Health Office. The data were collected by using a questionnaire based on the Regulation of the Minister of Manpower No. 5 of 2018 concerning Occupational Health and Safety in the Work Environment. The primary data obtained were then analyzed using cross-tabulation in a data processing software. Result: This research shows that, with an alpha of 5% (0.005), the relationship between gender and work stress events has a significance value of 0.013, while the relationship between exercise habits and work stress events has a significance value of 0.006. Conclusion: This research shows that there is a significant relationship between gender and exercise habits on stress events in Surabaya City Health Office employees. Women employees experience a higher incidence of work stress than male employees. Furthermore, the habit of exercising can reduce stress events because exercising can stimulate endorphins which play a role in creating a sense of calm, reducing pain, and releasing tension
