This process involves steps such as determining the project background, literature review to deepen understanding, data collection through Time Schedules, Budget Plans (RAB), weekly progress reports, and actual costs. Effective project management is the key to success in constructing the boarding school of SMA Muhammadiyah 3 Tulangan. Despite facing various challenges such as design changes, inclement weather, and limited workforce resources, the project is monitored using the Earned Value Method. Analysis of BCWS, BCWP, ACWP, SV, CV, SPI, and CPI indicates initial delays and budget overruns, but significant improvement later on. Despite weekly cost variations, the project remains financially manageable. The conclusion shows time delays but cost performance is under control. This underscores the importance of project performance evaluation and the use of the Earned Value Method in construction projects.

This is a basic principle in project management which is applied in various industrial sectors, including the construction of the Muhammadiyah 3 Tulangan High School dormitory. In this context, efforts to achieve project success involve careful planning, scheduling and control, taking these aspects into account (Arifin et al., 2023). Project management is a series of activities that aim to plan, schedule and control the course of a project in order to achieve the desired goals, both in terms of time, quality and cost (Muniroh et al., 2021). In the context of the construction of the MBS dormitory, project management is crucial to ensure that construction goes according to plan and on time. However, there is often a discrepancy between the initial plan and the realization in the field, which can result in delays and increased costs for the project. This is the main
