Abstract

The problem of Overdimension and Overloading (ODOL) freight transportation has become a national issue.  Various impacts caused by ODOL freight transportation include a decrease in vehicle speed, a decrease in road technical life, loss of road maintenance budget, vehicle damage, and the occurrence of traffic accidents on the road. East Java Province has a fairly high economic activity by using freight transportation in various conditions including Overdimension and Overloading. The Ministry of Transportation through the UPPKB Service Unit throughout East Java has made various efforts to handle ODOL freight transportation, but the level of violations of freight transportation still occurs. This study aims to determine the factors that affect the effectiveness of handling Overdimension and Overloading (ODOL) in freight transportation so that it can provide recommendations for appropriate ODOL handling. The data collection method used interviews and questionnaires to Korsatpel, UPPKB Operational Staff, and freight transport drivers. While the analysis method used fishbone diagram analysis and multiple linear regression analysis using field data. Based on the results of the study, it is known that the dominant factors that affect the effectiveness of handling Overdimension and Overloading (ODOL) in freight transportation are the enforcement of Tilang (X1) and Transfer of Cargo / Transfer of Excess Load (X3) with the value of coefficient determination at UPPKB Trosobo and Singosari of 96.1% and 92.3%. The handling recommendations given are the need to increase ticket fines and provide transportation services for excess cargo in the form of vehicles and transportation personnel as well as forklifts and cranes at the UPPKB Satpel to move heavy loads.

Abstract

The wheat silo and pellet silo structure repair project phase 3 by PT ISM Bogasari Surabaya is an annual infrastructure maintenance and strengthening activity aimed at supporting the smooth production process. Therefore, it is crucial to complete the project on time according to the contract to proceed to the next stage of repair and avoid delays that could result in cost overruns. This study uses Earned Value Method (EVM) analysis to address these issues and assess the performance of costs and implementation time as the project progresses. The indicators used in the analysis include the calculation of Estimated To Complete (ETC) and Estimated At Complete (EAC) for forecasting project completion costs, and Estimated Temporary Schedule (ETS) and Estimated All Schedule (EAS) for forecasting project completion time. Based on the results of the cost and time performance analysis, the EAC value is 0.77% smaller, which is Rp. 21,825,605,678, compared to the contract value. The time to complete the EAS project is 481 days, with an addition of 26 days, resulting in a 0.6% longer project completion time.

Abstract

The solution to the transportation problem lies in assessing the performance of related road sections and intersections, and analyzing different traffic management schemes to optimize efficiency. This study aims to compare the performance of a road network simulation model for the Pahlawan road area. Data analysis includes examining origin-destination matrices, vehicle free speeds, vehicle behavior, and intersection control. The simulation model, calibrated and validated using Vissim, represents real-world conditions. Implementing SLFF (Single Lane Free Flow) and MLFF (Multi Lane Free Flow) systems at toll gates (scenarios 1 and 2) reduced queues, particularly at the Pancasila Monument Roundabout and Jalan Jati Raya. Adding a new toll gate via Jalan Kahuripan further improved traffic on Jalan Pahlawan compared to scenarios 1 and 2. However, converting the Gelora Delta roundabout into an underpass without additional measures worsened toll gate queues. Effective traffic performance can be achieved by combining the Gelora Delta roundabout underpass with either the SLFF toll payment system (scenario 5), MLFF (scenario 6), or the addition of a new toll gate (scenario 3).

Abstract

The installation of the Baggage Handling System (BHS) at Sultan Hasanuddin International Airport, Makassar, faces challenges related to cost and time inefficiencies, particularly delays in project completion. This study aims to evaluate these inefficiencies by applying the Earned Value Method (EVM) to assess project performance and identify areas for improvement. Utilizing EVM metrics, the research identifies that the Schedule Performance Index (SPI) is below 1, indicating a delay in the project timeline, with the actual duration extending to 556 calendar days compared to the planned 546 days. This delay underscores the need for a more robust project management approach. The study employs the Critical Path Method (CPM) in conjunction with Microsoft Project to improve scheduling accuracy, alongside recommendations for project acceleration using the Crashing Program method. The findings highlight that early implementation of EVM can help mitigate discrepancies in cost and time, enabling better control and monitoring throughout the project lifecycle. The study concludes that integrating advanced scheduling techniques and real-time performance metrics is essential to achieving efficiency and minimizing delays in similar infrastructure projects.
