Abstract

The use of an inappropriate implementation method will result in a delay in project completion time, and conversely, a properly planned implementation method will result in a time-efficient project. In the Container Yard construction project for the Navigation Office and the KPLP Office in Banjarmasin, there was a discrepancy between planned and actual progress in the 23rd week of May, where the actual progress did not reach the planned progress on site. Project execution faced obstacles and constraints, including the availability of skilled labor and the limited supply of construction materials at the project site, as well as the late arrival of materials. In addition, there were also weather factors that caused the project duration to be slightly slower than planned. The earned value method is one of the methods used to analyze a project's time performance. This method can be used to calculate the estimated time required for project completion. This underlies this research to analyze earned value to determine the extent of the project's time performance. Furthermore, the use of the earned value method in this research object is based on the need to integrate project performance measurement, which includes time and work items. The results of the study show that time performance (Schedule Performance Index) has a value of less than 1, indicating that the project performance is slower than the planned schedule. Meanwhile, the Estimate All Schedule (EAS) value shows a value of 244 days, which is 4 days longer than the planned schedule.

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.

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

Construction activities for water pipeline projects in industrial facilities present various occupational and operational hazards that may disrupt project performance if not properly controlled. This study aims to analyze the occupational risks associated with the water pipeline construction project of PT CATL Karawang using the Hazard Identification, Risk Assessment, and Risk Control (HIRARC) method. The research was conducted through field observation, work breakdown structure analysis, and semi quantitative risk assessment based on likelihood and severity scoring. The results indicated ten (10) dominant hazards across five (5) major activities including trench excavation, pipe lowering, pipe joint installation, backfilling and compaction, pressure testing, and site restoration. Three (3) risks were categorized as high level, namely trench collapse, pipe dropping during lifting, and stuck by heavy equipment, while the remaining risks were classified as medium level. Appropriate risk controls are recommended following the hierarchy of control, emphasizing engineering controls, administrative procedures, and mandatory use of personal protective equipment. The study concludes that the overall risk category of the project is moderate, high and requires consistent monitoring and implementation of control measures to reduce the probability of incident and ensure safe and continuous project execution.

Abstract

This study analyzes physical workload and work-time efficiency in the tofu production process at UD Asal Lancar, where operations are still performed manually. A total of 12 production workers were included as research samples. Physical workload was measured using the Cardiovascular Load (CVL) method, work-time efficiency was evaluated through the Work Sampling method, and the optimal number of workers was determined using Work Load Analysis (WLA). The results show that the highest workload occurred in Worker 7, who recorded a CVL value of 53%, categorized as a heavy workload, while other workers fell into light to moderate categories. Work-time efficiency was found to be 84%, lower than the standard due to reduced effective working time caused by unproductive activities. The study recommends task redistribution, implementation of regular micro-breaks, and additional manpower in certain stages to balance workloads and improve work efficiency.
