Notification System and GPS Position Tracking as a Security Feature for Child Pick Up At Daycare

On the Internet of Things (IoT) era, specialized applications are highly demanded to solve real-life problems. We apply Haversine Formula in our proposed notification system and GPS position tracking method and choose daycare as our experimental object. The aim is to create a system that automatically connects teachers in daycare and parents when they are picked up. It allows teachers to track parents' location on the maps. This system is built using an Android-based application called “Child Pick Up (CPU)” with the login page being the first page that will appear when logging into the application. There is an option to sign up for a new parent account on this page. Then, the daycare teacher can verify the account. “CPU” application can send two notifications, when parents press the pickup button and when parents are less than 100 m from daycare. Based on the testing and analysis in this research, it can be concluded that the system can track a parent's location based on GPS position. The average distance when the second notification appears on the teacher's smartphone in daycare is 87.22 m. The pickup and arrival time is recorded on Firebase.
