The Effect of Noise and Work Fatigue on Work Productivity: Work Stress as a Mediator Among Airport Workers

Abstract

Introduction: One of the main problems at the airport is noise, which is an irregular wave that can endanger workers and the environment.
Objectives: The purpose of this research is to determine the effect of noise on work productivity through work stress and work fatigue as intervening variables among apron workers at Airport.
Methods: The method used is a quantitative research method with a cross-sectional study approach. Data collection from 101 respondents using the Depression Anxiety Stress Scales (DASS)-21 questionnaire, the Work Fatigue Scale questionnaire, the productivity questionnaire, and noise measurement using a Sound Level Meter. (SLM).
Results: The results show a significant direct effect of noise on work stress (C.R=3.261) and (p=0.001) indicating a significant effect, then a direct effect of work stress on work productivity (C.R=-3.056) and (p=0.002) indicating a significant negative effect. Additionally, there is a direct effect of work fatigue on work stress (C.R=2.519) and (p=0.012) indicating a significant effect. Meanwhile, through the analysis of indirect effects with work stress as a mediator, it was found that there is a significant effect of noise on work productivity (p=0.026) and (z-sobel= -2.232).
Conclusions: work stress has a significant influence in mediating the effect of noise on work productivity.
