Determinants of Musculoskeletal Disorders (MSDs) in Construction Workers in Medan Tuntungan District

Abstract

Construction workers are prone to Musculoskeletal Disorders (MSDs) due to the high physical demands of their work and their working environment. MSDs have a negative impact on workers' health and productivity. This study aims to analyze the partial and simultaneous effects of work posture, workload, and working environment temperature on MSD complaints among construction workers in Medan Tuntungan District. The study was conducted on 40 construction workers in Medan Tuntungan District. Data were collected through measurements of work posture (using QEC), workload (using CVL), environmental temperature (using Heat Index), and MSD complaints. Data analysis used multivariate analysis with multiple linear regression tests. The residual data were normally distributed (Sig. = 0.200 > 0.05). Simultaneously, work posture, workload, and temperature significantly influenced MSD complaints (Sig. = 0.000 < 0.05). Partially, work posture significantly influenced MSD complaints (Sig. = 0.030 < 0.05), and workload (Sig. = 0.025 < 0.05). However, environmental temperature did not significantly influence MSD complaints (Sig. = 0.205 > 0.05). The combined contribution of the three variables to MSD complaints is 41.6%. Work posture and workload are significant determinants of MSD complaints among construction workers in Medan Tuntungan District. Therefore, efforts to prevent MSDs should focus on improving work posture and managing workload.
