Abstract

The development of educational infrastructure is a crucial aspect in supporting the improvement of the quality of learning and human resource development in Indonesia. However, in its implementation, construction projects often face challenges in the form of delays in completion and cost inefficiencies, which impact the disruption of the educational process and increase the budget. This study aims to analyze the cost efficiency and acceleration of the implementation time of the Sunan Ampel Jombang Junior High School construction project through the crashing method approach, which is a technique in project management used to accelerate project completion time by selectively adding resources to critical activities. The delay in the start of a project is the main problem faced by the implementers of the Sunan Ampel Jombang Junior High School construction project, resulting in delays in final completion and an inflated project value. Based on the analysis conducted, this study also provides solutions to overcome this. The results of the analysis of the Sunan Ampel Jombang Junior High School construction project show an additional cost of Rp. 163,845,745.00 from the normal work cost to Rp. 2,623,114,845.00, an increase of 0.93%. This research provides practical contributions for project managers and contractors in making strategic decisions related to controlling project time and costs and can be a reference in managing the risk of project delays in the future.

Abstract

The Situbondo – Ketapang – Banyuwangi Road and Bridge Preservation Project experienced changes in the work area, requiring additional design. Asphalt overlay work was halted awaiting the test results of Asphalt Modiv PG – 70 from the Pusjatan Road Material Laboratory in Bandung, resulting in a delay in week 40 by -0.813%. Specifically, AC - WC and AC - BC asphalt work was delayed, significantly impacting the overall project performance. Cost and time analysis are crucial to address this issue. The Earned Value Management (EVM) method is used to evaluate project duration and costs. The Cost Performance Index (CPI) indicates good cost performance (>1), but the Schedule Performance Index (SPI) indicates schedule delays (0.983 < 1). The final project cost is estimated at Rp 112,439,121,070.91, with a completion time of 453 days, three days longer than planned. Effective strategies are needed in time control and design adjustments to complete the project according to expected standards.

Abstract

The reconstruction of the Surabaya-Gempol Toll Road underscores the critical role of effective project management in large-scale infrastructure projects, particularly in ensuring time and cost efficiency. This study employs the Earned Value Method (EVM) to evaluate project performance through the analysis of Schedule Variance (SV) and Cost Variance (CV). These indicators provide a comprehensive assessment of the project's adherence to its planned schedule and budget. The findings reveal that the project faced initial schedule delays due to logistical and technical challenges, resulting in negative SV values during the early weeks. These delays were primarily caused by weather conditions, late material deliveries, and coordination issues among project stakeholders. However, corrective measures, including extended working hours, additional labor deployment, and optimized scheduling, successfully addressed these issues, leading to positive SV values towards the end of the project. The CV analysis highlighted consistent cost efficiency throughout the project. Positive CV values dominated the majority of the timeline, reflecting effective cost control and resource management. Despite minor cost deviations due to unanticipated repairs and equipment maintenance, the project demonstrated an ability to maintain overall financial performance within the budget framework. This study emphasizes the significance of data-driven decision-making and proactive variance management in achieving project goals. By leveraging SV and CV analyses, infrastructure projects can better anticipate potential issues, implement timely corrective actions, and improve overall performance. The results of this research offer valuable insights for managing similar large-scale projects, contributing to enhanced efficiency and sustainable development in Indonesia's infrastructure sector.

Abstract

This research addresses the critical issue of insufficient budget allocation for Occupational Safety and Health (OHS) systems in construction projects, specifically in the Rubaru 1 Elementary School building project in Sumenep District, Indonesia. The study explores how limited financial resources for safety measures, such as personal protective equipment (PPE), worker training, and health facilities, affect the implementation and effectiveness of OHS systems. The urgency of this research lies in the growing need to allocate adequate resources to OHS, as insufficient funding increases the risk of workplace accidents, delays project timelines, and raises costs. Previous studies, including Lestari et al. (2023) and Saragi & Sinaga (2021), have emphasized the positive impact of adequate OHS budgets on reducing accidents and improving productivity. However, a gap exists in research regarding the specific cost components required for effective OHS implementation, especially in relation to construction projects with limited budgets. This study fills this gap by analyzing the key cost components for OHS and their direct impact on worker safety and project performance. The findings will provide valuable insights for construction companies to optimize their OHS budgets and enhance safety measures. It also contributes to the development of industry standards and practices for OHS management in future construction projects.

Abstract

The construction of the Regional General Hospital Dr. H. Slamet Martodirdjo in Pamekasan Regency faces several challenges, particularly concerning high-level risks that may impact project success. This study aims to identify and analyze major risks affecting project completion and propose effective mitigation strategies. Using a survey method, data were collected from key stakeholders and processed using the Severity Index and Probability and Impact Matrix to assess risk levels. The findings identified 25 potential risks, with eight categorized as high-level risks: implementation method errors, difficulties in installing cross foundations, delays in critical path tasks, late material procurement, labor shortages, non-compliance with occupational safety regulations, lack of teamwork among workers, and adverse weather conditions. These risks significantly impact the project timeline, budget, and overall quality. The study also reveals that poor coordination among stakeholders, inefficient risk management practices, and regulatory constraints contribute to project delays. To mitigate these risks, strategic planning, improved procurement management, workforce training, and strict adherence to occupational safety regulations are recommended. Additionally, the adoption of technology-driven solutions, such as digital monitoring systems and e-procurement platforms, can enhance project oversight and efficiency. By implementing a systematic risk management framework, construction projects can minimize potential disruptions, ensure timely project delivery, and maintain cost efficiency. The findings of this study provide valuable insights for project managers, contractors, and policymakers in the construction industry, particularly for large-scale healthcare infrastructure projects. A proactive risk mitigation approach is essential to achieving successful project execution and sustainable infrastructure development.

Abstract

This study aims to analyze project cost and time acceleration using the Crashing Method by adding three hours of overtime work and additional labor. Delays in construction projects often lead to budget overruns and inefficiencies, making acceleration techniques essential for ensuring timely project completion. The research evaluates cost efficiency by comparing the total project budget before and after implementing the Crashing Method. Using both qualitative and quantitative approaches, this study examines the impact of different acceleration strategies on cost increase and time reduction. The findings indicate that project completion time can be significantly reduced using both methods; however, overtime results in higher cost increases compared to additional labor. While overtime provides immediate acceleration, it incurs higher expenses due to increased labor wages, whereas adding workforce results in gradual but more cost-effective acceleration. Furthermore, the study underscores the importance of selecting the appropriate acceleration approach based on project constraints, workforce availability, and financial considerations. Effective resource allocation, labor management, and risk assessment are critical factors in minimizing costs while maximizing efficiency. By analyzing the trade-offs between cost and time, this study provides valuable insights into the optimal strategy for project acceleration in construction management. The findings offer practical recommendations for contractors, project managers, and stakeholders to optimize resources and maintain budget control while ensuring project completion within the scheduled timeframe.
