Abstract

This research aims to determine the influence of the quality of human resource management on the performance of contractor companies in North Sumatra. The hypothesis proposed is that there is a positive relationship between the quality of human resources and the performance of contractor companies. A total of 24 respondents from 6 contractor companies were selected as samples using the probability sampling method. The research results show that there is an influence between the quality of human resources on company performance. This is proven by the results of the hypothesis test which shows the calculated t value of 10.785, exceeding the t table value of 2.074. Therefore, the null hypothesis is rejected, indicating that there is a significant influence between the quality of human resource management and the performance of contractor companies in North Sumatra. From the research results, it can be concluded that the quality of human resource management has a significant influence on the performance of contractor companies in North Sumatra 84.1%; the remaining 15.9% is influenced by other factors. Therefore, it is recommended to improve the quality of human resource management to improve the performance of contractor companies.

Abstract

Infrastructure projects implemented under the Public–Private Partnership (PPP) scheme have a high level of risk complexity due to the long-term division of technical, operational, and occupational safety responsibilities. The Sitinjau Lauik 1 Flyover project is characterized by extreme topography, landslide potential, and heavy equipment mobilization, all of which increase the likelihood of construction and occupational safety risks. This study aims to analyze the influence of risk mitigation strategies on construction risk control in PPP projects. The research method employs a descriptive quantitative approach based on the frameworks of ISO 31000 and SMK3, as well as Failure Mode and Effects Analysis (FMEA), using severity, occurrence, and detection parameters to obtain the Risk Priority Number (RPN). The results indicate that there are 31 primary risks, with the highest priority levels originating from technical aspects in the field, such as heavy equipment accidents, potential landslides, inconsistencies in construction methods, and risks associated with working at elevation. The mitigation strategies implemented—including improvements in work methods, periodic inspections, enhancement of workforce competence, and strengthening of the supervision system—have been proven to reduce risk levels from high to medium and low categories. The study concludes that the systematic implementation of risk mitigation strategies has a significant effect on reducing construction risk levels and improving the safety and performance of PPP projects.
