Micro, Small, and Medium Enterprises (MSME) Seblak Buffet often experience long queues and inefficient waiting times, especially during peak hours, which negatively impact customer comfort and service quality. This study aims to analyze and analyze the business's queue system using the FIFO (First In First Out) model to improve service efficiency and fairness. Using a quantitative approach with M/M/1 modeling, on arrival times and following exponential distribution service, data were obtained from direct observation. The simulation results show that although FIFO maintains order, waiting times increase significantly during peak hours due to limited facilities. Therefore, this study recommends adding waiters or rearranging service flows during peak hours as an applicable solution to improve quality and customer satisfaction.
