Bengkalis Island is located between the island of Sumatra and Malaysia and is surrounded by the Melaka Strait and the bengkalis Strait. The Melaka Strait and the bengkalis Strait are the traffic of ships such as import-export ships, company ships, passenger ships, freight ships, fishing boats, passenger ships, and illegal ships. According to news circulating in the official media, ship accidents such as fishing boats often occur. This happens because many fishing boats do not have or use AIS technology. This research proposes the application of Automatic Identification system (AIS) transponder for safety monitoring of fishing boats. This system can track the position of surrounding ships and can be tracked through the Polbeng AIS base station, so that it can be monitored directly through the Polbeng AIS application. The trial was conducted directly on the ship located in the bengkalis strait. From the results of the experiments carried out, it shows that the system can track ships around and can be tracked through AIS Polbeng, so that ship safety is more guaranteed and monitored.
