Analysis of Project Implementation Time Using the Crashing Method on the Construction Work of Sunan Ampel Jombang Middle School

Abstract

Educational infrastructure development is a crucial aspect in supporting the improvement of the quality of learning and human resource development in Indonesia. However, in its implementation, construction projects often face challenges in the form of delays in completion and cost inefficiencies, which impact the disruption of the educational process and increase the budget. This study aims to analyze the cost efficiency and acceleration of the implementation time of the Sunan Ampel Jombang Middle School construction project through the crashing method approach, namely a technique in project management used to accelerate the project completion time by selectively adding resources to critical activities. The delay in the start of a project is a major problem faced by the implementers of the Sunan Ampel Jombang Middle School construction project, resulting in delays in final completion and resulting in an inflated project value. Based on the analysis conducted, this study also provides solutions to overcome it. The results of the analysis of the Sunan Ampel Jombang Middle School Construction project obtained the results of additional working hours with a reduction in duration of 15 days from normal time to 135 calendar days, with an additional cost of Rp. 149,104,602.00 from the normal cost of the work to Rp. 2,608,373,702.00 or an increase of 0.94%. While the results of the analysis with the addition of labor obtained a reduction in duration of 28 days from normal time to 122 calendar days, with an additional cost of Rp. 163,845,745.00 from the normal cost of the work to Rp. 2,623,114,845.00 or an increase of 0.93%. This research provides practical contributions for project managers and contractors in making strategic decisions related to controlling project time and costs, and can be a reference in managing the risk of project delays in the future.
