Abstract

The problem of public roadside parking (TJU) in Surabaya City, as one of the metropolitan cities in Indonesia, is a complex issue and requires serious attention in its management. This study aims to analyze the characteristics of TJU parking, evaluate its potential contribution to regional own-source revenue (PAD), and identify supporting and inhibiting factors in increasing parking retribution. The data obtained from the parking spot survey was comprehensively analyzed to identify parking characteristics and their effects on road sections, ultimately informing recommendations to enhance parking capacity and efficiency in the future. The results of this study provide a useful tool for policy makers to understand the distribution of parking demand across the city, leading to a clearer understanding of parking usage patterns and challenges. The presence of illegal parking, as seen in cities like Jakarta and Medan, also adds complexity to the management of the parking problem. The adoption of e-parking systems, as implemented in several other cities, can improve the efficiency of parking levy collection. Furthermore, the adoption of modern technologies has proven effective in improving parking revenue and reducing operational inefficiencies.

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

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.

Abstract

The advancement of industrial activities requires high-performance management to achieve desired outcomes, particularly in complex projects such as construction. This study aims to analyze the application of the Statistical Process Control (SPC) method to improve product quality in the construction project of the Java Residence Cluster in Sidoarjo. Managing cost, time, and quality remains a significant challenge in construction projects. This research focuses on identifying and addressing complaints or defects in housing units that affect the quality of the project, using SPC as a quality control method. Data were collected from primary sources, specifically from the staff of PT. Mitra Usaha Konstruksi, as well as secondary data from relevant literature. The analysis shows that the application of SPC successfully reduced the number of complaints or defects from 5.95 complaints per unit in Cluster 1 Phase 3 to 3.12 complaints per unit in Cluster 2 Phase 1, with an effectiveness rate of 52.47%. Pareto analysis identified that the majority of complaints were related to doors, windows, and wall paint, suggesting that these areas should be prioritized for improvement in future construction projects. The study recommends the continued use of SPC to improve product quality and identify the root causes of defects to ensure compliance with the developer's quality targets.
