		abstract={Direct physical contact in the health facility is a very high risk for patients because it can increase the risk of being exposed to Covid-19, moreover, patients are people who are not healthy or have congenital diseases, which certainly increases the risk of being exposed to Covid-19. The purpose of this study is to build a hospital patient queue and registration system model that is implemented on the Android platform. The method has applied to this system model is the Haversine method which is used to calculate the distance between the patient's coordinates and the hospital coordinates as a reference for the system in sending notifications. For testing the haversine method on the system using a percentage and Mean Squeared Error (MSE). The results of the haversine method test with an accuracy of 99.4281% and an MSE error of 0.280, with high accuracy and low error rates prove that the haversine method is very suitable to be applied to systems for calculating distances. This system makes it easier for patients to register online and helps patients queue flexibly at a certain radius by sending queuing notifications to reduce physical contact with other patients or with health facilities officers}
