Abstract

Abstract- Supervision of children is an important thing to do for the development of behaviour and child safety. The existence of cases around such as after school not going straight home, skipping school to play online games, even in the mass media there are cases of elementary school children who do not go home immediately. in the mass media there are cases of elementary school children who died from drowning while playing. This can cause parents to worry about their children. On the other hand, the space for parents to supervise children directly is limited due to their activities such as taking care of the house or working, so there is an alternative to make a tracking device or GPS Tracker with the concept of the Internet of Things (IoT) that can solve the problem. The manufacturing method includes three stages, namely the design stage, the testing stage, and data analysis stage in order to produce the expected tool. The results of this research are first, GPS Tracker is built by three main components (Ardunino Nano, Ublox NEO-6M, and SIM800L). Second, the tool functions optimally when outside the room with percentage of error 0% and less than maximum when indoors with an error of 40%. room with 40% error. Third, the device is able to track position at various distances. Fourth, the tool has an average working endurance of 4 hours 26 minutes with a power source of 3.7 VDC 3500mAH battery.

Abstract

Mosques are places of worship for Muslims. With a large number of mosques, the problems that arise are also diverse, for example the AL Akbar Surabaya mosque has 2 thefts per year. The form of breaking into the charity box was in the form of the destruction of the padlock hinge made of iron plates in the outer courtyard of the mosque. This is a problem for mosque managers. The purpose of this research is to create a security system for the charity box of the Al Akbar National Mosque that can be controlled remotely using the Internet of Things (IoT). This system will ensure the safety of the charity box and prevent the possibility of theft or manipulation of the money contained in it. This security system uses motion sensors as an indicator of suspicious activity around the charity box. When the vibration sensor detects vibration, the system will activate the Buzzer and the ESP32 CAM camera takes pictures to be further processed using a face detection algorithm and the results are sent in the form of a notification to the mosque manager who is connected to the internet network, so that it can take photos that can be accessed in real-time by security control. To control this security system, a mobile application will be built that can be accessed by mosque administrators. Overall, this design will provide a higher level of security for the Al Akbar National Mosque charity box. With a security system that can be accessed and controlled remotely through IoT. The mosque management can quickly respond and take action in unsafe situations.
