Abstract

The construction of the Malaka Regency Regent's Office has faced significant challenges, including frequent delays in project completion due to various factors such as design changes, unpredictable weather conditions, labor shortages, and inadequate materials or equipment. These issues have led to inefficiencies in time and cost management, emphasizing the need for effective project management strategies. This study applies the Critical Path Method (CPM) to analyze the project timeline, identify the critical path, and propose measures for project acceleration. By employing CPM, the project schedule was meticulously reviewed and optimized, resulting in a reduction of the initial planned duration from 180 calendar days to 100 calendar days. This acceleration was achieved by minimizing lag times between critical activities, reallocating resources, and implementing time-cost trade-off strategies, all without compromising the quality or scope of the project deliverables. The results demonstrate the effectiveness of CPM in streamlining construction project timelines and mitigating delays. Additionally, this study provides a practical framework for addressing time and cost overruns in construction projects, particularly in the context of public infrastructure development. By highlighting the integration of project management tools like CPM, this research contributes to the broader understanding of efficient scheduling practices and offers actionable insights for similar projects in the future.

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

Purpose: This study examines the influence of bureaucratic leadership style, work culture, and work discipline on employee performance at the Riau Islands Provincial Secretariat, with work motivation as an intervening variable. Research Methodology: Using a quantitative approach, 165 employees were selected as respondents from a population of 279 employees. Data were analyzed using structural equation Modelling (SEM) with AMOS 24.0. Results: The findings show that bureaucratic leadership style and work discipline significantly influence employee performance, whereas work culture has no significant direct effect. All three factors–leadership style, work culture, and discipline—positively and significantly affect motivation, which in turn strongly influences performance. Furthermore, motivation successfully mediated the relationships between leadership style, work culture, discipline, and employee performance, strengthening the overall causal model. Conclusions: Employee performance is primarily shaped by effective leadership, strong discipline, and supportive motivation, with work culture playing an indirect role. Motivation is a central driver that enhances the impact of leadership and discipline on performance outcomes. Limitations: This study is limited to a single public sector organization, with cross-sectional data that may not capture long-term dynamics. Future studies should incorporate other variables, such as teamwork, compensation, and organizational trust. Contribution: This study contributes to the public management literature by demonstrating the mediating role of motivation in linking bureaucratic leadership, culture, and discipline with performance, offering insights for policy and managerial practices in government institutions.
