Abstract

The implementation of construction projects often faces various risks that can lead to delays, cost overruns, and decreased quality of work. One example occurred in the project to build a dormitory for students of the Riyadlus Sholihin Islamic Boarding School in Probolinggo City, which experienced a time deviation despite acceleration efforts. This shows the importance of implementing systematic risk management to identify and address potential risks from the beginning of project implementation. This study uses a descriptive quantitative approach through the dissemination of questionnaires and interviews to related parties in the project. The analysis was carried out using the Severity Index method to calculate the level of probability and impact of each risk, as well as the probability and impact matrix to determine the level of risk significance. The dominant risk is then further analyzed to determine mitigation actions. The results of the study showed five risks with a "Very High" level, namely the preparation of the wrong work method, poor coordination between parts, the accuracy of completing work within a certain duration, poor planning and scheduling, and low labor productivity. Mitigation strategies are developed to reduce the impact of these risks, including through training, improved communication, the use of planning software, and strengthening the monitoring system. This research makes a real contribution to the risk management of construction projects in a more effective and structured manner.

Abstract

Bridge infrastructure plays an important role in supporting connectivity and regional economic growth. However, in their implementation, bridge construction projects often face delays due to technical factors such as weather, soil conditions, as well as managerial and coordination constraints. One of them occurred in the Purworejo Bridge construction project in Mojokerto Regency which experienced a delay in progress of -14.88% in the 12th week of implementation. This delay requires accelerated efforts so that the project is not included in the critical contract category. This study seeks to examine the approach of accelerating implementation time through the Crashing method through increasing working hours (overtime) and calculating costs efficiently to mitigate delays. The methodology used includes the formulation of a network using Microsoft Project, the identification of critical paths through the Critical Path Method (CPM), and the calculation of acceleration costs based on Cost Slopes. The results of the analysis show that the acceleration of work can be achieved both technically and economically. This method allows the project to reduce delays, thus removing them from the classification of vital contracts. The study significantly improved the decision-making process for the timely and cost-effective implementation of development projects.

Abstract

This study investigates the cost implications of accelerating the construction of the Trenggalek Religious Court Office Building in response to delays caused by flooding. Utilizing the crashing method, two acceleration strategies were evaluated: adding overtime hours and increasing workforce. The results indicate that reducing the project duration from 240 days to 180 days through overtime incurs a cost increase primarily due to additional pay, while reducing it to 170 days by adding workers results in higher labor costs. Detailed analysis of durations, costs, and cost slopes for each activity provides valuable insights for project managers to select the most cost-effective acceleration approach. Additionally, a comparative analysis of normal and crashing schedules for various construction tasks highlights potential efficiencies in scheduling and budgeting, ultimately aiding in timely project completion within optimized costs.

Abstract

This study aims to analyze the character and service strategy for sleeper bus consumers on the Malang-Jakarta route based on the perspective of users. Through a survey approach involving questionnaire instruments, this study integrates the Kano and SERVQUAL methods to identify customer needs and evaluate the gap between expectations and perceptions of service quality. Analysis of user needs characteristics was carried out to understand what attributes are considered important and significantly affect the level of satisfaction in the context of sleeper bus services. The results show that some service attributes fall into the must-be and one-dimensional categories, which are proven to have a strong impact on user satisfaction. Meanwhile, SERVQUAL's analysis identified negative gaps in several service dimensions, especially in terms of reliability and responsiveness. Based on these findings, this study formulated a service improvement strategy that focuses on optimizing priority attributes, improving operational processes, and strengthening comfort and security aspects. This research is expected to contribute to the development of a more responsive and customer-oriented intercity transportation service strategy.
