T The selection of methods in a project is one of the highly considered aspects to achieve results in accordance with the initial planning. Project management is an effort to efficiently, effectively, and on schedule manage limited resources in the completion of a pre-planned project. The use of methods such as overtime and shift work is carried out by identifying critical activities and shortening their durations while still maintaining the quality and safety of work implementation.The total cost of crashing the overtime system for Project X with a percentage increase of 1.63%, and for the shift system of Project Y, the percentage increase is 2.43%. The total cost of crashing the overtime system for Project Y with a percentage increase of 1.63%, and for the shift system of Project Y, the percentage increase is 2.52%. It is found that the total duration of Shift Y, from the normal project duration of 120 days, is reduced to 84 days after acceleration, which is faster compared to crashing Project X, where the normal project duration of 120 days is reduced to 104 days after acceleration. It is then discovered that the total duration of Shift Project X, from the normal project duration of 120 days, is reduced to 84 days after acceleration, which is faster compared to crashing Project X, where the normal project duration of 120 days is reduced to 104 days after acceleration.
