Abstract
It is recorded that around 100 people per year die due to fishing boat accidents, the majority of whom are small fishermen with vessels under 10 GT. LoRa is a license-free power-saving long-distance communication technology that can send data packets of up to 15 km in the ocean. The longrange power can be used to determine the location of fishermen when an accident occurs at sea. This research aims to implement and test the performance of LoRa Ebyte E22-400T30D for sending coordinate data on fishermen’s whereabouts in the form of life jackets. The performance observed is the relationship between the distance and the RSSI value obtained. The tests were performed until the furthest distance was reached. The test was carried out at Pangandaran Beach, and the receiver was placed at an altitude of 129 m toward the beach. The data will be displayed and stored on the Thinger.io website. The test results obtained with the furthest distance achieved were 12.983 km with a battery life of 5.99 hours. The RSSI value obtained tended to worsen with increasing distance. Apart from the distance, it was also found that obstructions in the form of trees could reduce the RSSI value.
