Abstract

This study focuses on identifying and mitigating risks associated with constructing the Probolinggo-Banyuwangi Toll Road Project Package 2, a vital segment of Indonesia's Trans-Java Toll Network. The background highlights the project's significance in enhancing regional connectivity and supporting economic growth alongside the challenges it faces from technical, managerial, financial, social, and environmental factors. This research aims to identify critical risks and develop effective mitigation strategies. The methodology involves data collection through interviews, surveys, and document analysis, prioritizing risks based on their probability and impact. Key findings reveal that delayed delivery, rising material prices, and lack of skilled labor are the most significant risks, demanding targeted mitigation strategies. The conclusion emphasizes the importance of implementing real-time risk monitoring systems, improving logistics coordination, and fostering stakeholder collaboration, particularly with government agencies. By prioritizing critical risks and developing comprehensive mitigation strategies, this research contributes valuable insights for managing complex infrastructure projects, ensuring project sustainability and success.

Abstract

This study evaluates the financial feasibility of constructing the South Surabaya Regional General Hospital using key investment evaluation methods, including Net Present Value (NPV), Internal Rate of Return (IRR), benefit-cost ratio (BCR), and Payback Period (PP). The study also examines how changes in management costs affect the project's financial viability. Data collected includes both initial investment costs and ongoing operational expenses. The findings indicate that the project is financially viable, with a positive NPV, an IRR higher than the required rate of return, and a payback period shorter than planned. Sensitivity analysis highlights that management costs significantly influence the project's feasibility. These insights can help the Surabaya City Government optimize hospital management costs and ensure the sustainability of healthcare projects.

Abstract

This research examines the efficiency of managing the construction of the Public Safety Center (PSC) building in Probolinggo Regency. Effective management ensures the project meets its timeline, budget, and quality goals. We used a method called Earned Value Analysis to track progress and identify potential issues early on. Key indicators like the Cost Performance Index (CPI) and Schedule Performance Index (SPI) helped us understand how well the project was performing in terms of cost and schedule. The research revealed challenges such as material delays and labor shortages, which impacted the project's efficiency. By analyzing these issues, we propose solutions to improve project planning and execution, focusing on better resource allocation and scheduling. The findings offer valuable insights for future construction projects, helping to minimize delays and overspending. This research emphasizes the importance of identifying project performance issues promptly to ensure overall success. The recommendations can guide improvements in construction project management, ensuring projects are completed on time, within budget, and to the required quality standards.
