Abstract

The project acceleration by the Crash Program is one of the ways that is often used to make time and cost efficiency on an ongoing project. Acceleration of project completion time will affect the efficiency of equipment and labor productivity. In the case study of the Surabaya Outer East Ring Road Project Construction Segment 1, a project that has the potential to be accelerated is discussed in order to obtain efficiency values in terms of time and cost, Project acceleration by means of the Crash Program using the Precedence Diagram Method (PDM) method to determine the value of efficiency. This project uses resources, in this research the software used is Microsoft Project 2016. The research method used is to design network planning, find the critical path for each job, determine the work that has the potential to be accelerated, calculate the crash cost in additional working hours. and work shifts, calculating direct costs and indirect costs for each activity that changes due to changes in the duration of implementation, calculating the cost slope. Application of the Crash Program in the work of Asphalt Concrete Surface Layers (AC) thick 5 cm in the project will have an impact on increasing the time efficiency previously planned from 180 working days to 175 working days and efficiency with the difference in project costs of Rp. 18.313.935,8 with a ratio of 0,997 between the PDM method compared to the cost of the contract value calculated using the crashing project method.

purpose: The purpose of this study is to examine and analyze the influence of servant leadership and organizational culture on human resource performance with job satisfaction as an intervening variable in the Drainage Division of the Water Resources and Highways Service of Surabaya city Goverment. Methods: This study uses a causal research design with a quantitative approach. The research was conducted at the Water Resources and Highways service office, Drainage Division, Jimerto street no. 6-8, Ketabang Village, Genteng District, Surabaya city, East Java. The population in this study consisted of 94 civil servants and non-civil servants working in the Drainage Division of the Water Resources and Highways service office Surabaya city Goverment. The sampling technique used the census method, so that the number of samples taken was 94 employees of the Drainage Division. Data collection was carried out by distributing questionnaires. The data analysis technique used was SEM (Structural Equation Model) based on Partial Least Square (PLS) version 4.1.1.5. Results: The results of this study prove that servant leadership has no effect on job satisfaction, organizational culture has a positive and significant effect on job satisfaction, servant leadership has no effect on employee performance, organizational culture has a significant and positive effect on employee performance, and job satisfaction is unable to mediate servant leadership and organizational culture on employee performance. Implications: These findings imply that strengthening organizational culture should be prioritized over servant leadership to enhance job satisfaction and employee performance in public sector organizations.
