Abstract

The development of physical facilities in Indonesia is increasing rapidly along with the promotion of modernization. In the implementation of a project it is very rare to find a project that goes exactly as planned. Generally, they experience delays from what was planned, both in terms of time and progress of work, but there are also projects that experience acceleration from the initial schedule planned. The research objectives were to determine time and cost performance, and to determine cost estimates and final project completion time for the Well Pad stockpiling and compaction project in the Rokan Riau Oil and Gas Block environment. The method used in this study is the Earned Value method which combines the elements of cost and time as well as the physical performance of the work. The data obtained from the project includes the project time schedule, budget plan (RAB), project weekly reports and actual costs, then an analysis of costs, schedules, variances and performance indexes is carried out by explaining the problems that arise during the research. Based on the results of the analysis and discussion, the calculation of the CPI value is> 1 from the 1st week to the 16th week. This means that from the 1st week to the 16th week, the project cost is more economical. The EAS calculation for the 16th week estimates the project completion time is 116 days or 16 weeks. This means that the project is experiencing a delay from the planned schedule. At the end of the review period, an estimated final project cost of Rp. 4,022,024,000.00. And the estimated time for project completion is 116 days, which means the project will be completed in a longer time than planned, which is 211 days.

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.

Abstract

This research evaluates the condition of the pavement on the Maospati - Bts. Magetan City with the Surface Distress Index (SDI) method. The results showed the average value of SDI < 50, indicating that the road condition is in good category with minor damage. The dominant damage types are longitudinal cracks and small holes. Based on the survey results, the estimated maintenance cost required reached Rp. 333,468,376, including patching, slurry seal, and crack sealing works. This study confirms that the SDI method is effective for road maintenance planning and budget allocation in an efficient manner. This strategy not only prolongs the service life of the road but also minimizes long-term maintenance costs. Moreover, sustainable road maintenance practices play a crucial role in supporting regional connectivity and development. Well-maintained roads facilitate smoother transportation, enhance logistics efficiency, and improve access to social and economic services, contributing to inclusive and sustainable growth in Magetan Regency.

Abstract

Mojokerto is a region in East Java with strategic geographical and economic significance, serving as a key area for regional connectivity and growth. However, the Bendung-Bantengan road section has experienced considerable damage due to inadequate retaining walls, leading to road subsidence, cracks, and increased maintenance costs. These challenges necessitate effective soil stabilization measures to ensure the safety and functionality of the infrastructure. This study explores the application of Value Engineering (VE) to optimize the planning and construction of retaining walls in the region. Utilizing secondary data from topographic surveys and triaxial soil tests, this research evaluates three design alternatives to identify the most efficient solution. The analysis revealed that Alternative 1 demonstrated the highest cost efficiency, achieving a reduction in construction expenses by IDR 284,244,698.00 through the optimization of structural dimensions and material usage. In addition to cost savings, the implementation of VE also contributed to a shortened project timeline, reducing the completion period to 121 days from the originally planned 180 days. The design maintained its quality and structural stability, effectively resisting lateral soil pressure while mitigating erosion risks. This study underscores the significance of incorporating VE during the planning stages of infrastructure projects. By balancing cost efficiency, quality, and sustainability, VE enhances project value and ensures long-term resilience. The findings provide a strategic framework for future infrastructure projects, promoting sustainable and economically viable solutions for regions with challenging geotechnical conditions. VE’s integration into construction practices highlights its transformative potential in achieving efficient and durable infrastructure development.

Abstract

The Kemlagi–Beratkulon road surface assessment in Mojokerto District covers a section of 3.637 km and features a combination of rigid pavement, flexible pavement, and asphalt. This road plays a critical role as a connecting link between Mojokerto District and Gresik District, supporting transportation and regional connectivity. The primary objective of this study is to evaluate the road surface condition, measure the extent of surface damage, and classify the condition using the International Roughness Index (IRI) method. Data collection was conducted through field surveys with the aid of the Roadroid application, providing real-time measurements of road roughness. The findings reveal that the highest e-IRI value recorded was 1.75 at STA 1+900 to STA 2+000, indicating a road condition classified as "GOOD" based on IRI standards. The study highlights the efficiency of the IRI method in assessing road conditions, ensuring accurate identification of surface damage levels ranging from good to severely damaged. Furthermore, the use of the Roadroid application proves effective in facilitating rapid and precise road surface evaluations. To enhance future assessments, this research suggests integrating alternative android-based applications for comparative analyses and conducting surveys during low-traffic periods to minimize data inaccuracies. These findings contribute to the broader understanding of road infrastructure management, emphasizing the importance of regular assessments to optimize maintenance efforts, extend road lifespan, and allocate resources effectively.
