The design of this location-based smart airport model illustrates in a simple way the principle of Radar equipment as a solution to public problems at the airport terminal, where currently the direction information to the location of the facilities needed by flight service users is in conventional form in the form of information boards, so that visibility due to age factors, limited time flight service users are in the terminal, the dense number of flight service users and the large terminal area becomes an obstacle. Based on the duties and functions of the airport manager, namely providing services by prioritizing safety, comfort and security, by applying the principle of radar that is able to detect, measure distance, identify and track objects in the surrounding environment in the form of digital displays. This smart airport model is designed digitally and is able to provide information which is the result of tracking objects to the location of public facilities contained in the airport terminal area in the form of information on the guiding path to the location, the length of time and distance that can be taken to the location of the facility. This study aims to determine the level of validity of the Smart Airport simulation design with location determination in the introduction of radar courses using ISO 25010 testing. The subjects of this research are material experts and media experts. The research procedure used by adapting the Research and Development (R&D) development model with the ADDIE method with 5 stages, namely: Analysis, Design, Development, Implementation, and Evaluation. To measure product quality, validation of material experts and media experts was used. The data sources are material experts, and media experts. The type of data is quantitative data (questionnaire). The instrument used in data collection is a questionnaire instrument using a Likert scale and a Guttman scale. The data collection technique was carried out by observation, and questionnaires. The data analysis technique used is descriptive analysis with reference to the quantitative data obtained. The results of this study are in the form of smart airport simulation design products at the Makassar Sultan Hasanuddin International Airport terminal as a solution to the needs of flight service users at the departure terminal that can be connected to smartphones as a medium for the convenience of passengers and Makassar Sultan Hasanuddin Airport managers. The results of ISO 25010 testing of smart airport applications in terms of validity amounted to 3.79 in the valid category.
