摘要：The purpose of this study is to monitor the data sent from the ship to the server. This system relies on the internet network to transmit data such as the coordinates of ship position, the direction vessel, the distance of obstacles in a front vessel, the speed vessel, and the length of ship trajectory to the server using the GSM Shield SIM900 module. This study will use four providers such as Telkomsel, XL Axiata, Indosat, and Tri. The benefit of this ship monitoring system research is that it can monitor supervision on ships and access via mobile phones. The result of this study is the system can respond well and send data on the coordinates, the direction, the distance of the obstacle in a front vessel, the speed, and the length of the vessel trajectory. Then the best signal strength is using a Simpati card provider with a signal strength of -65 dBm.
