Abstract

Poor indoor environmental conditions are often associated with reduced concentration, lower motivation, and decreased productivity in office settings. Addressing this issue requires a systematic assessment of Indoor Environmental Quality (IEQ) and its contribution to work performance. This study examines the effect of Indoor Environmental Quality (IEQ) on office worker performance, focusing on five components: Indoor Air Quality (IAQ), Thermal Comfort, Lighting Quality, Acoustic Quality, and Occupant Experience. The Best-Worst Method (BWM) was applied to determine the relative importance of these factors through a combination of subjective surveys and objective weighting using linear programming. Results indicate that Occupant Experience, particularly ergonomic improvements such as adjustable furniture and optimized layouts, has the strongest influence on productivity. Thermal Comfort ranks second, followed by Lighting Quality, Acoustic Quality, and IAQ. Sensitivity analysis confirms the robustness and consistency of the findings. This research contributes by offering a systematic weighting of IEQ factors, highlighting the central role of ergonomics in workplace design. The study emphasizes that integrating ergonomic and environmental considerations is essential to improve worker performance. The novelty of this study lies in integrating Occupant Experience into the BWM framework, providing a more comprehensive model of IEQ and offering new insights for designing healthier and more productive office environments.

Abstract

This study aims to analyze Musculoskeletal Disorders (MSDs) complaints in shoe production workers at PT XYZ and evaluate work postures using the Posture Evaluation Index (PEI) approach. The methods used include data collection through direct observation, distribution of Cornell Musculoskeletal Discomfort Questionnaire (CMDQ), and posture assessment using OWAS, RULA, and REBA methods. The results showed that complaints most often occurred in the upper back, neck, and right shoulder, which were mostly caused by non-ergonomic work postures. The PEI assessment showed that the work section with the highest risk was the packing section, with a score of 2.7 indicating the need for immediate improvement. After improving the work posture according to ergonomic principles, the PEI score decreased to 1.6, indicating increased comfort and decreased risk of injury. This study emphasizes the importance of periodic ergonomic evaluations to improve work comfort and productivity.

Abstract

This study aims to determine the effect of music tempo on work productivity and the level of cognitive failure among employees in the fabrication division of PT. Adi Joyo Kusumo. Music is used as an intervention to address boredom and stress caused by monotonous work. This research employs the Cognitive Failure Questionnaire (CFQ) method distributed to 12 employees, and observations were made on production quantities over seven days under three conditions: without music, fast tempo music, and slow tempo music. The results indicate that fast tempo music yields the highest productivity level with a total production of 26 units, followed by the no music condition (23 units) and slow tempo music (21 units). Validity tests show that all CFQ items are valid, and reliability tests yield a Cronbach’s Alpha value of 0.921, indicating reliability. ANOVA tests show a significance value of 0.000 (p < 0.05) and an F value of 17.078, indicating a significant effect of music tempo on cognitive failure levels. Although fast tempo music can enhance work performance, the noise level reached 89 dB, disturbing other divisions. This study concludes that fast tempo music can be used as a productivity enhancement strategy, provided that noise levels are controlled to avoid negative impacts on other work environments.
