Abstract

Introduction: Potential ergonomic hazards at work can lead to complaints of musculoskeletal disorders (MSDs). The Global Burden of Disease estimated that, by 2019, there were about 1.71 billion people in the world living with musculoskeletal problems. One of the jobs that has this risk is librarians because their jobs are dominated by static postures. This study aims to determine the correlation between work posture and body mass index (BMI) with MSDs complaints among librarians at Universitas Airlangga. Methods: This study is an analytical observational research with a cross-sectional design. The sample of this study consists of the total population of librarians at Universitas Airlangga that met the inclusion criteria, totaling 28 librarians. Primary data were obtained through the direct distribution of questionnaires to librarians, observations of work posture and musculoskeletal complaints in librarians. The data in this study were analyzed using the Spearman rank correlation test. Results: The research results showed that the level of mild MSDs complaints was reported by 7 librarians (25.0%), moderate complaints by 13 librarians (46.4%), and severe complaints by 8 librarians (28.6%). The statistical test results indicate a strong and positive correlation between work posture and MSDs complaints (r = 0.444), while a weak and positive correlation was found between BMI)(r = 0.222) and years of service (r = 0.158) with musculoskeletal disorders complaints. Conclusion: This study concludes that librarians in high-risk work postures may experience musculoskeletal disorders complaints, especially in the neck, shoulders, and back areas.

Abstract

Introduction: The discrepancy between actual heat stress and workers' perception results in a mitigation failure, potentially leading to fatality. This study aimed to investigate workplace heat stress, workers' workload, and personnel's heat strain in steel mills under extreme temperature conditions. Methods: The study used a mixed-methods design and was conducted across three steel mills in East Java, Indonesia. An analysis of heat-stress data included heat-stress symptoms derived from physiological and environmental factors, while the personal perception assessment was based on comprehensive interview sessions. These quantitative results, obtained from 119 operators, were compared with workers' personal thermal perceptions using a mixed-methods approach. Phase 1 quantitative method consisted of onsite data collection, walkthrough inspection, questionnaire distribution, workplace monitoring, personal assessment, and statistical analysis. Phase 2, as a qualitative stage, consisted of in-depth interviews and focused group discussions with 15 participants. Results: The wet-bulb globe temperature measurements confirm significant heat stress in all mills. Workers' physiological responses remained within acceptable limits according to ACGIH criteria. However, a noticeable discrepancy was found between the quantitative data and workers' perceptions, highlighting the need for greater awareness and training on heat-stress hazards. Conclusion: The alignment between qualitative and quantitative findings underscores the importance of integrating both approaches to develop effective mitigation strategies. This study contributes to understanding occupational heat stress in high-risk environments and emphasizes the need to incorporate worker perceptions into health and safety protocols.
