Abstract

Introduction: The chance of respiratory diseases among workers participating in toll road construction projects is, for example, higher because of non-organic dust. Therefore, this study aims to evaluate the level of lung capacity experienced by the workers by exposing them to dust and wearing masks. Methods: This cross-sectional study investigated toll road projects in Central Java and Yogyakarta and randomly selected workers from different strata of construction companies. The volume Air Sampler estimated dust concentration, while the pulmonary function test included spirometry. All data were analyzed using two-way MANOVA. Results and Discussion: The multivariate analysis of variance showed that workers exposed to dust exceeding the Threshold Limit Value (TLV) had significantly reduced FEV1 and FVC averages (p < 0.001). The averages of FEV1 and FVC increased more considerably in mask users than non-users, indicating mask usage's benefits. The decline in lung function was smaller in mask users, with FEV1 (95% CI: 0.080–0.321) and FVC (95% CI: 0.071–0.404). A reduction in walking distance also demonstrated significance to the decrease in FVC. Conclusion: They found that dust in construction declines lung capacity, but wearing masks provides some protection. However, such impact continues even after stopping wearing masks, thus stressing the importance of correct mask usage and staff training. Subsequent research must investigate dust interaction and various types of masks to enhance Indonesian workers’ health.

Abstract

Background: Occupational accidents can result in financial losses for the company and decreased worker productivity. These incidents are often caused by unsafe actions and conditions. At PT X, several work activities pose a high hazard, including being struck by heavy loads, falls from heights, entrapment by machinery, vehicle-related accidents, and fires. Purpose: This study aims to analyze the effect of Behavior-Based Safety implementation on unsafe actions in workers at PT X. Method: This quasi-experimental study using a pre-test and post-test approach with a control group design. In this research, a total of 70 workers will be divided into two groups, namely the intervention group with the application of BBS and the control group. The implementation of BBS consisted of four stages: (1) Define, (2) Observe, (3) Intervention Program, and (4) Test. The study data were processed and analyzed using the SPSS application. Result: The study demonstrated that the implementation of Behavior-Based Safety (BBS) successfully reduced unsafe actions, as reflected in the Mann-whitney Test results showing a ρ-value = 0.043 (ρ-value < 0.05). Conclusion: The application of BBS serve as an effective effort to reduce unsafe worker actions and therebyminimize occupational accidents.
