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.

Abstract

This study investigates the factors influencing the potential audit findings in Design and Build (DB) construction projects in Indonesia, employing Structural Equation Modelling–Partial Least Squares (SEM-PLS) and Importance–Performance Map Analysis (IPMA). Data were collected from 100 respondents, including project owners, contractors, and construction management consultants. The SEM-PLS results reveal that Integrity & Compliance Culture (β = −0.169, p = 0.045) and Administrative & Financial Compliance (β = −0.193, p = 0.027) significantly reduce the probability of audit findings, while other technical factors such as planning, supervision, and team competence show no direct effect. IPMA highlights Integrity & Compliance Culture and Contract & Documentation Management as top improvement priorities. These findings demonstrate that governance and compliance dimensions are more critical than technical performance in shaping audit outcomes. Strengthening compliance culture, enhancing administrative transparency, and implementing robust contract management are therefore key strategies to minimize audit risks in DB projects. The study contributes to the applied statistics literature in construction management and offers practical insights for policymakers, contractors, and auditors aiming to achieve accountable and transparent infrastructure delivery in Indonesia.

Abstract

Indonesia, as a strategic global maritime axis, has only 7.03% of its islands equipped with jetties, and jetty construction poses environmental challenges due to emissions and ecological impacts. Green retrofitting provides a sustainable solution by improving energy efficiency in existing jetties. The Envision rating system guides the transition from conventional to green infrastructure, assessing quality of life, leadership, resource allocation, natural environment, and climate resilience. Despite its benefits, 32% of green projects experience delays. This study analyzes the key factors influencing time performance optimization in Green Retrofit Jetty projects using Lean–Value Stream Mapping (VSM). Using SEM-PLS, ten critical factors were identified. Lean–VSM facilitates process visualization and waste elimination. The Green Retrofit Jetty, achieving an Envision Platinum rating, reduced project duration from 250 to 220 days, demonstrating a 12% improvement in time performance while supporting efficient and sustainable jetty development.

Abstract

This study investigates the operational impact of four key infrastructure systems (HVAC, lighting, electrical equipment, and internal transport) on staff performance at Terminal 3 of Soekarno-Hatta International Airport. Despite consuming 86.59% of the terminal’s energy, HVAC systems show no statistically significant contribution to staff performance. In contrast, lighting, electrical equipment, and internal transport significantly improve staff productivity, with internal transport having the highest influence. A structural equation modeling approach using PLS-SEM and Importance-Performance Map Analysis (IPMA) was employed to analyze data from 400 respondents. The model yielded strong explanatory (R² = 0.613) and predictive relevance (Q² = 0.505), validating its robustness. Findings suggest that energy management in airport terminals should shift from consumption-based to performance-based prioritization, favoring infrastructure investments that directly enhance operational efficiency.

Abstract

This study analyzes risk management related to the role of Independent Quality Control Consultants during the transition of toll road infrastructure project funding from Toll Road Business Entities (BUJT) to the State Budget (APBN). The funding transition introduces complex regulatory, technical, and coordination challenges that may affect project quality, time performance, and compliance. Therefore, this research aims to examine the influence of competence and risk assessment on the effectiveness of PMI performance, with stakeholder management positioned as an intervening variable. A mixed analytical approach was employed using Structural Equation Modeling–Partial Least Squares (SEM-PLS) and the Analytical Hierarchy Process (AHP). SEM-PLS was applied to test causal relationships among variables, while AHP was used to determine the priority level of factors influencing PMI effectiveness. Data were collected from professionals involved in toll road infrastructure projects, including consultants, contractors, supervisors, and academics. The results show that competence and risk assessment have a significant positive effect on the effectiveness of PMI performance. Furthermore, stakeholder management significantly mediates the relationship between competence and performance, as well as between risk assessment and performance, indicating that effective communication, coordination, and collaboration enhance the impact of technical capabilities and risk control. The AHP analysis reveals that the implementation of government regulatory standards is the most influential factor, followed by professional independence, ethical integrity, and human resource competence in understanding public funding regulations. In conclusion, the effectiveness of PMI during the BUJT-to-APBN funding transition depends on an integrated approach that combines regulatory compliance, professional competence, structured risk assessment, and stakeholder management. These findings provide strategic insights for policymakers and practitioners in strengthening quality control systems within toll road infrastructure projects.
