<![CDATA[The development of information technology has driven significant changes in hotel operations, particularly in the Front Office Department, which serves as the main point of guest service. The implementation of an integrated information system connecting the Front Office Department with other hotel departments, such as Housekeeping, Accounting, and Reservation, has improved service effectiveness through reservation processes, check-in, check-out, guest data management, and the preparation of integrated operational reports. This study aims to analyze the implementation of an integrated information system between the Front Office Department and other hotel departments at Loji Hotel, as well as its contribution to supporting the operational performance of the Front Office Department. This research employed a descriptive qualitative approach, with data collected through interviews. The findings indicate that the implementation of an integrated information system facilitates reservation processes, accelerates check-in and check-out services, improves the accuracy of guest data records, and enhances the exchange of operational information between the Front Office Department and other departments, including Housekeeping, Accounting, and Food and Beverage, resulting in more effective and efficient guest services. In addition to improving employees' work efficiency, the information system also supports faster, more accurate, and higher-quality services, thereby increasing guest satisfaction. Therefore, the implementation of an integrated information system plays an important role in supporting the operational performance of the Front Office Department at Loji Hotel.]]>
