Abstract

This study analyzes the performance of construction projects using the Earned Value Method (EVM) on the Infrastructure and Facilities Improvement Project at Yohanis Kapiyau Airbase in Timika. Utilizing key performance indicators such as Cost Variance (CV), Cost Performance Index (CPI), Schedule Variance (SV), and Schedule Performance Index (SPI), the research evaluates cost and time deviations to provide a comprehensive understanding of project performance. EVM offers precise insights into the project's current status, including estimates for total costs and completion timelines, which are critical for effective decision-making and ensuring adherence to project plans. The findings demonstrate that EVM is a reliable tool for accurately monitoring and managing construction projects, enabling stakeholders to identify inefficiencies and implement corrective measures in a timely manner. By providing an in-depth evaluation of cost efficiency and schedule performance, the study contributes to the broader application of EVM in enhancing construction project management. This research is expected to benefit academics by advancing theoretical knowledge, assist contractors in optimizing project execution, and inform public stakeholders on best practices for infrastructure development, ultimately contributing to more effective and efficient management of construction projects in Indonesia.

Abstract

The optimization of traffic light settings plays a crucial role in managing vehicle flow, reducing congestion, and improving road performance, particularly in critical segments such as the toll overpass of Sidodadi in Sidoarjo Regency. This study focuses on addressing two key research questions: the impact of heavy vehicle traffic on intersection performance and the effectiveness of proposed strategies for long-term traffic management. Using the Indonesian Highway Capacity Manual (MKJI) 1997, traffic data during peak hours were analyzed to identify delays, degree of saturation, and service levels under existing traffic conditions. The findings revealed that the high volume of heavy vehicles significantly exacerbates delays and reduces intersection efficiency. To address this, two main strategies were proposed: restricting the operational hours of heavy vehicles and implementing dedicated heavy vehicle lanes. Additionally, long-term measures, including intersection redesign and the application of Adaptive Traffic Control Systems (ATCS), were evaluated. The results highlight the need for immediate interventions and continuous evaluation to ensure sustainable traffic flow and support regional mobility and economic growth.
