Polije Students Develop LoRa Fisherman Navigation System Without Internet

A student team from Politeknik Negeri Jember (Polije) successfully created an innovative LoRa (Long Range) based fisherman navigation and tracking system that can operate without an internet connection.

The innovation, developed by Alfin Bintang Fariski, Adenta Faiza Priatama, and Permanik Dwi Ayuningtyas, aims to improve the safety of fishermen during activities at sea, aligning with aspects of SDG 9 (Industry, Innovation, and Infrastructure).

Alfin Bintang Fariski explained the system’s mechanism, which consists of two main devices. He detailed how the data is transmitted from the sea back to the land station.

“The transmitter carried by the fisherman obtains coordinate data from the satellite, then sends the raw data latitude and longitude to the receiver on land via the 915 MHz LoRa module,” Alfin explained.

Alfin added that the technology development took two months. The system then processes the coordinate data into a Google Maps link that fisherman families can access via a smartphone. This real-time monitoring capability significantly contributes to maritime safety.

“Family members on land can monitor the fisherman’s movements in real-time with visualization on Google Maps, facilitating monitoring, especially in emergency situations,” Alfin added.

This innovation is expected to reduce the risk of maritime accidents and increase operational efficiency for fishermen. The team hopes that this system can be widely adopted in various coastal areas and integrated with the national monitoring system for Indonesian fisherman safety.
