In this study, we use Lora-based data communication for communication between boats and database management systems for vessel. The maximum distance from the Lora is 10 km, and in order to be able to monitor fishermen along the fisherman’s coast in fishing, it is necessary to have a multi-gateway Lora to increase fishermen’s tracking coverage. The system is built using multi gateway Lora installed on the coast. Devices built with a Lora client are installed on a boat with GPS input, the technique of sending data on the device to the gateway uses a time base with a 1-minute period. To minimize data on the gateway that intersects the range of other gateways, a time flag is made to determine the data at a certain time to determine the trajectory of the boat. The result this research is system-monitoring vessel, which is successfully built and can provide fishing boats along the coast with long-range coverage. Based on experiment, multi gateway can be implemented by creating an identical ID gateway, the Lora client will broadcast to the nearest gateway. The maximum distance obtained is 1.35Km NLOS and to cover 20 Km of beach length is needed 15 gateways.

Implementation of LPWAN very large application, such as remote location, agriculture, mining, and transportation. This paper discusses for data format on implementation small vessel tracking for traditional fisherman. data format is very important for tracking system can be monitoring vessel simple. data format can be optimized perform on IoT network, such as delay, bandwidth, range and power consumption energy. Data format with 68 Bytes Strings stream to gateway Lora every 3 seconds. Data format for gateway to Broker server utilize MQTT format with 4-way connection, such as connect, connect ack, publish data and disconnect. Based on experiment, data format can use robust for small vessel and can implemented on this application.
