Abstract

Toll road maintenance requires effective and efficient strategies to ensure that repair work can be completed quickly without reducing construction quality, particularly in projects using rapid-setting concrete. This study aims to analyze the variables affecting contractor quality performance in the implementation of fast-drying concrete pouring on the maintenance of the Jakarta Outer Ring Road (JORR) sections W2S, S, and E, as well as to identify the most dominant factors influencing project quality. The study employed a quantitative approach using Structural Equation Modeling-Partial Least Squares (SEM-PLS) combined with Importance Performance Map Analysis (IPMA). Data were collected through questionnaires distributed to 96 respondents consisting of project owners, contractors, supervising consultants, and rapid-setting concrete producers. The results revealed that material management, work motivation, work equipment, and work environment significantly influenced project quality performance. Material was identified as the most dominant factor with the highest total effect value, while communication significantly affected work motivation as a mediating variable. The model explained 67.9% of the variance in project quality performance. In conclusion, improving material management, strengthening work motivation, optimizing equipment readiness, and creating a supportive work environment are essential strategies for enhancing the quality of fast-drying concrete maintenance projects on toll roads.

Abstract

The implementation of port infrastructure development often faces challenges related to soft soil conditions that require effective ground improvement methods. Cement Deep Mixing (CDM) has become one of the widely applied techniques for enhancing soil strength and stability; however, its performance is influenced by various technical, managerial, external, and implementation quality factors. This study aimed to evaluate the performance factors affecting the CDM project, identify gaps between the importance and actual performance of these factors, and determine improvement priorities using Importance–Performance Analysis (IPA) and the Customer Satisfaction Index (CSI). A quantitative approach using a survey method was applied to the ABC Port Project, involving 85 respondents consisting of contractors, main contractors, and supervisory consultants directly involved in CDM implementation. Data were collected through questionnaires based on 15 indicators covering technical factors, managerial factors, external conditions, and implementation quality, and were analyzed using IPA and CSI methods. The results showed that the overall CDM project performance was categorized as good, with a CSI value of 87.57%, indicating a very high level of stakeholder satisfaction. However, the analysis revealed a negative performance gap of -0.06 between stakeholder expectations and actual project performance. The highest improvement priorities were related to technical training (M2) and operator and technician competency (M1), indicating the need for stronger human resource development and technical control. This study concludes that the integration of IPA and CSI provides an effective evaluation framework for identifying critical factors and developing targeted strategies to improve CDM project performance.

Abstract

Cut Mutia Raya Road, located in East Bekasi, is a road that connects Bekasi City with Bekasi Regency and has a very important role in the development of Bekasi City and its surroundings. The high number of U-turn movements on this road section affects the performance of the road section, which causes disturbances for motorists both from the same direction and from the opposite direction and has the potential for traffic conflicts, in addition to congestion caused by the impact of the distance between the median opening facilities (U-turn). The aim of this study is to determine the characteristics of traffic flow on this road section using the PKJI-2023 method, get the performance value of the U-turn facility, and find out how much influence the U-turn facility has on the performance of the road section. The method used is by making direct observations in the field to obtain geometric data of road sections, traffic counting for the volume of vehicles on the road section, and those that turn back at the U-Turn facility to be further analyzed using the PKJI-2023 method and the 2005 U-Turn Planning Guidelines method. Based on the survey data in the field, the peak hour volume of vehicles on Wednesday, 13 November 2024, was 4.016 vehicles/hour (3.100 vcu/hour), with a Degree of Saturation (DJ) value of 0,74. The free flow speed is 55,2 km/h, and the MP passenger vehicle speed based on DJ is 46 km/h. The volume of vehicles making a U-turn at the U-turn is 731 vehicles/hour (406,6 vcu/hour). With a vehicle waiting time of 10,12s with a queue length of 3,12m and a delay of 12,04s.

Abstract

Design coordination in toll road projects involves many stakeholders with high information exchange needs, potentially causing process waste such as waiting time, repeated inspections, design revisions, and information delays, which reduces coordination effectiveness and impacts design completion duration. The application of Building Information Modeling (BIM) through the Common Data Environment (CDE) is expected to enhance information integration and collaboration among stakeholders, thereby increasing design coordination effectiveness. This study aims to analyze the effectiveness of the application of BIM-CDE in the design coordination process in toll road infrastructure projects through waste identification and process performance measurement. The research uses a mixed methods approach with a case study design. Data were obtained through observation, study of project documents, and semi-structured interviews. The analysis was carried out using Value Stream Mapping (VSM) to identify Value Added (VA), Non-Value Added (NVA), and supporting activities, then evaluated using waiting time, lead time, and Process Cycle Efficiency (PCE) indicators. The results of the study identified four types of waste, namely waiting, transportation, defect, and overprocessing. The implementation of BIM-CDE was able to reduce the waiting time from 72 days to 25 days (65.28%), while the total lead time was reduced from 255 days to 134 days (47.45%). In addition, the PCE value increased from 27.45% to 31.34% indicating an improvement in process efficiency. This study was limited to one project case study so generalizations of results are still limited. Further research is suggested to test the application of BIM–CDE on different projects.

Abstract

The unsignalized intersection which is located in Cileungsi District, precisely on Jalan Cileungsi Setu and Jalan Raya Narogong, is a commercial area with dense economic activity and densely populated settlements. As a result of the dense activity, congestion occurs due to the large number of vehicles passing the road, especially during peak hours, namely the morning and evening. Seeing this problem, an analysis is needed that aims to determine the volume, performance of roads, and unmarked intersections as measured by capacity, degree of saturation, and level of service.  In analyzing this study using the Indonesian Road Capacity Manual (MKJI) 1997 method which will determine the performance of roads and intersections without signs. The data needed in this research are primary data in the form of geometric road data, traffic volume, vehicle speed data, and side friction. As well as secondary data in the form of location maps, land use, and population data. From the results of data analysis and processing, the busiest traffic flow at the intersection occurred on Sunday, November 15, 2020 at 17.30 - 18.30 WIB, the saturation degree value was 1.17 with LOS F. By doing an alternative solution, the saturation degree value was 0.68 and LOS B with placing signs are prohibited from stopping around intersections, and prohibiting the flow of traffic turning right either from the main road D to the Minor C road or from the Minor C road to the main road B. On Jalan Raya Narogong, the degree of saturation is 0.74 LOS C service, this shows that the road sections do not exceed the figure required by MKJI 1997, namely ≤ 0.75.

Abstract

This study evaluated the actual condition of physical facilities, identified service-quality bottlenecks, and formulated strategic interventions to improve intermodal integration performance between the South Sumatra Light Rail Transit (LRT) and the Musi Emas feeder service in Palembang City, with Asrama Haji Station and Polrestabes Station serving as case studies. Primary data were collected through field observations based on national regulations (Ministry of Transportation Regulation No. PM 41/2015 and No. PM 29/2019, and Ministry of Public Works Regulation No. 14/PRT/M/2017) and through a questionnaire distributed to 374 respondents selected using probability sampling. The data were analyzed using a combination of multivariate methods, including SERVQUAL gap analysis, the Customer Satisfaction Index (CSI), Importance–Performance Analysis (IPA), and Partial Least Squares Structural Equation Modeling (PLS-SEM), with data processing conducted using SmartPLS 4 and SPSS. The overall evaluation indicated a high level of commuter satisfaction, with an overall CSI score of 87.8%, categorized as “Very Satisfied.” The IPA Cartesian diagram showed that most of the 18 service attributes were distributed across Quadrants I and IV, indicating that core physical infrastructure and LRT operational punctuality generally performed well, although attributes in Quadrant I still required priority improvement because of their high importance and comparatively lower performance. The structural model assessment (R² = 0.639 for the Performance model and R² = 0.831 for the Satisfaction model) indicated that satisfaction was influenced not only by physical infrastructure but also by interpersonal and nonphysical service performance. The Empathy dimension (X5) demonstrated the strongest effect, with a path coefficient of 0.390, followed by Comfort and Safety (X4 = 0.276) and the Information System (X3 = 0.272).
