Abstract

This study is a quantitative research using an explanatory approach that aims to analyze the influence of compliance with the Occupational Health and Safety (OHS) Program and leadership on the work quality of employees in the low-cost apartment construction project in DKI Jakarta, both directly and indirectly through work motivation as a mediating variable. The population of this study consists of 800 project implementation employees at one of regional owned enterprises engaged in the property and infrastructure sector, with a sample of 267 respondents determined using the Slovin formula at a 5% margin of error. Data were collected through a survey using a Likert-scale questionnaire and analyzed using the Structural Equation Modeling (SEM) method with the help of AMOS software version 22.00. The results show that compliance with the OHS Program has a significant positive effect on work quality but does not significantly affect work motivation. Leadership has a significant positive effect on both work motivation and work quality. Furthermore, work motivation serves as a significant mediating variable in bridging the effects of the OHS Program and leadership on work quality. The mediating effect of work motivation on the relationship between leadership and work quality is stronger than its effect on the relationship between the OHS Program and work quality. These findings indicate that in addition to the importance of implementing the OHS Program, effective leadership plays a strategic role in enhancing the motivation and work quality of construction project employees.

Abstract

This study aims to examine the effects of Occupational Health and Safety (OHS) compliance, Human Resource Management (HRM), and Transformational Leadership (TLD) on the project quality of residential building construction. The research focuses on high-rise residential building projects that present specific challenges in managing OHS, human resources, and leadership. The population includes workers, project managers, and related personnel involved in residential building construction under the Ministry of Public Works and Housing (PUPR). A purposive sampling technique was used to select 384 respondents based on their roles and direct involvement in the project. Data were analyzed using Structural Equation Modeling (SEM) to test direct and indirect relationships between variables. The results indicate that OHS, HRM, and TLD have significant positive direct effects on project quality, with standardized estimates of 0.356, 0.404, and 0.253 respectively, at a 99% confidence level. Additionally, transformational leadership also has a significant indirect effect on project quality mediated by OHS and HRM, with estimates of 0.055 and 0.060 respectively. These findings suggest that in residential building projects, transformational leadership plays a crucial role not only in directly improving project quality but also indirectly through enhancing effective OHS practices and human resource management.
