One of the infrastructures driving tourism is the existence of hotels, every industry engaged in providing services and hospitality services must be very good in terms of service, cleanliness, and customer satisfaction priority. The check-in process at every hotel is almost the same, but in this digital era, there are still hotels that use the manual method, and the old computerized system which is the cheapest system which makes the check-in process less efficient and effective. Computer problems and weaknesses often occur, such as a slow system, problematic hotel guest room charges, sometimes double paying guests, and the registration process, check-in and check-out are still manual. This is necessary for information system to simplify the work process, solve problems, and speed up the process. Information system design method using SDLC (Systems Development Life Cycle).
