Gor Ki Mageti Magetan is a sports hall located in Magetan Regency, East Java, Indonesia. Based on its functions, it can be seen that this facility greatly supports various community activities. The scheduled rental data from January to December 2023 recorded a total of 130 rental requests. However, the current reservation process is still carried out manually, which often leads to several issues. Manual reservations require manual record-keeping, increasing the risk of information errors and unorganized booking queues. Based on these challenges, it is necessary to develop an information technology-based application for sports hall rental at Gor Ki Mageti Magetan that can facilitate the booking process, provide schedule information, minimize double bookings, and improve service quality through the implementation of the First Come First Served (FCFS) algorithm. The study is entitled “Sports Hall Rental Application Using the First Come First Served Algorithm at Gor Ki Mageti Magetan.” The findings show that the system functions as expected, covering sequential reservations, identical time slots, and input validation. Moreover, the application of the FCFS algorithm successfully prioritizes booking queues based on the earliest input or arrival order, ensuring that requests are processed fairly and systematically until completion.
