Analysis of the Impact of the Implementation of the Construction Safety Management System (SMKK) on the Cost and Time of Implementation of the River Normalization Project
Abstract
The implementation of the Construction Safety Management System (SMKK) has become a regulatory mandate in Indonesia and plays a vital role in enhancing infrastructure project performance. This study aims to evaluate the impact of SMKK implementation on cost and time performance, using the Kali Banter River normalization project in Desa Tani Bhakti, Loa Janan District, Kutai Kartanegara Regency as a case study. The project had a contract value of IDR 777,777,700, with safety-related allocations—covering personal protective equipment (PPE), training, signage, insurance, and safety personnel—constituting 3.61% of the total budget. A quantitative descriptive approach was applied to assess cost distribution and time deviations based on weekly progress reports. The results indicate that, despite its relatively low financial allocation, the SMKK significantly contributed to the project being completed on schedule, with zero deviations across the 13-week execution period. These findings suggest that safety investments are instrumental in mitigating operational risks and ensuring schedule adherence. The study highlights the importance of integrating SMKK not only as a regulatory requirement but also as a strategic and cost-effective management approach. Furthermore, it underscores the need for local governments and contractors to reinforce their commitment to construction safety culture, particularly in public infrastructure development.
