Abstract

The transportation sector plays a vital role in supporting urban residents' daily activities and improving their quality of life. It encompasses two critical components: facilitating movement and physically relocating goods and passengers from one place to another. Public transportation systems are essential for enhancing urban mobility, reducing traffic congestion, and promoting environmental sustainability. This study focuses on analyzing the condition and service quality of the public transportation system operated under the Buy The Service (BTS) scheme on the Gresik-Lamongan route. The research employs a mixed-methods approach, combining primary data gathered through questionnaires distributed to passengers and field observations with secondary data obtained from the East Java Provincial Transportation Office, Gresik Regency Transportation Office, and Lamongan Regency Transportation Office. Using the Importance Performance Analysis (IPA) method, this study evaluates key service attributes to identify gaps between passenger expectations and actual service delivery. The findings reveal that the Transjatim Corridor IV route serves a 53-kilometer journey with an estimated travel time of 1 hour and 40 minutes. It operates with 14 buses and 1 spare fleet and is equipped with safety features such as seat belts, fire extinguishers, and glass-breaking hammers. The service is popular among various demographics, including students, workers, and tourists, due to its affordability, comfort, and strategic connectivity. However, certain service indicators, such as fleet availability, punctuality, and cleanliness, require improvements to better meet passenger expectations. This research highlights the importance of continuous evaluation and enhancement of public transportation services to achieve optimal satisfaction and operational efficiency. The results provide valuable insights for policymakers and transportation operators in designing strategies to improve the quality of mass transit services, ensuring they are safe, efficient, and accessible to all user groups.

Abstract

In the Kandya House Villa Construction project in Ubud, Bali, there was a delay with a time deviation of -11.97%. This delay has the potential to cause the completion time of the work, which according to the contract is scheduled for 53 weeks, to be exceeded. To evaluate the time and cost performance in this project, the Earned Value method was used. This method utilizes three main indicators, namely Actual Cost of Work Performed (ACWP), Budgeted Cost of Work Performed (BCWP), and Budgeted Cost of Work Scheduled (BCWS). The results of the analysis show that the project time performance has decreased, characterized by a Schedule Variance (SV) value of -Rp 375,265,411.62. This value reflects a significant difference between planned and completed work. In addition, the Schedule Performance Index (SPI) was recorded at 0.772, which means that time efficiency only reached 77.2% of the planned schedule. As a result, the projected completion of work using the Estimate to Schedule (ETS) and Estimate at Schedule (EAS) indicators increased to 421 days or equivalent to 60.090 weeks, far exceeding the contract duration. In terms of cost, the analysis shows suboptimal performance, with a Cost Variance (CV) value of -Rp 48,700,590.06. This indicates that the actual costs incurred were higher than the planned budget for the completed work. In addition, the Cost Performance Index (CPI) value was recorded at 0.963, which means that the efficiency of budget utilization only reached 96.3%. Overall, the results of the analysis showed that from both time and cost aspects, the project experienced a significant decline in performance. This indicates the need for improvement efforts to get the project back on track, especially through more effective schedule control and budget management.

Abstract

The construction project of Rumah Ru Guest House and Main House experienced delays due to a lack of careful initial planning and narrow access roads that hampered the delivery of materials. These obstacles affected the overall construction progress. To overcome these problems, the Earned Value Method (EVM) was used to analyze project performance in terms of cost and time. EVM uses three main indicators, namely Actual Cost of Work Performed (ACWP), Budgeted Cost of Work Performed (BCWP), and Budgeted Cost of Work Scheduled (BCWS). The research data was obtained from the executing contractor, CV. Cipta Karya Utama. The results of the analysis show that the project performance in week 15 to week 21 experienced problems, indicated by negative values in Schedule Variance (SV) and Cost Variance (CV). This reflects the delay of work from the planned schedule and cost overruns. In addition, the Schedule Performance Index (SPI) and Cost Performance Index (CPI) values of less than 1 also confirm that the project's time and cost performance is not optimal. These findings emphasize the need for improvement in future project planning, particularly in anticipating logistical barriers and managing resources for more efficient project performance

Abstract

Road damage is a common issue that arises due to various factors, including substandard construction quality, overloaded vehicles, and extreme weather conditions. The road segment connecting Lumajang City Limits to Jember District Limits has been identified as experiencing deterioration at several locations, predominantly caused by vehicles carrying loads that exceed the maximum allowable capacity. This study focuses on evaluating the current condition of the road, estimating the required repair costs, and assessing the economic feasibility of implementing the repairs. The research methodology incorporates field surveys to gather primary data, such as the extent, severity, and distribution of road damage, along with secondary data on traffic volumes and vehicle loads. The analysis involves classifying road conditions and calculating repair costs using the overlay method, which considers structural improvements needed to restore optimal functionality. The results indicate that out of the total road length, 1.66 kilometers are classified as being in good condition, 1.3 kilometers are in fair condition, 7.2 kilometers have minor damage, and 4 kilometers are severely damaged. These findings provide essential insights for prioritizing repair works and formulating cost-effective strategies to improve road infrastructure in the region.

Abstract

This study analyzes the impact of traffic growth on the pavement design life of KH. Ahmad Dahlan Pohjentrek Road in Pasuruan City using the Manual for Pavement Design (MDP) by Bina Marga 2024. The increasing volume of traffic, especially from heavy vehicles, has led to accelerated road deterioration and a significant reduction in the pavement's planned design life. The CESAL (Cumulative Equivalent Standard Axle Load) values exceeded the initial projections, reducing the planned lifespan from 10 years to 8 years. This finding highlights the critical need for regular evaluations of pavement thickness and the implementation of stricter monitoring systems for heavy vehicle loads. Advanced technologies, such as Weight-in-Motion (WIM) systems, can be instrumental in real-time vehicle load monitoring, thereby preventing further deterioration. Additionally, revising pavement designs to incorporate more robust materials and increasing layer thickness can enhance road durability. This study emphasizes the importance of adaptive and proactive road management strategies, including policy adjustments and routine maintenance programs, to ensure the longevity and functionality of critical infrastructure, particularly in regions experiencing rapid traffic growth. The findings serve as a reference for local governments and stakeholders in developing sustainable road management practices
