Floating Net Cages (KJA) Refers to a method of raising fish that involves the use of floating nets that have a rectangular or cylindrical shape. Conventional floating net cages which are usually used for fish farming do not have a propulsion system. If the water contained in the floating net cages has poor water quality, therefore a floating net cage is needed that can move automatically to find good water quality. To carry out the movement, a floating net cage is needed. additional devices, namely buoys (buoys) as a detector of the best location of air quality. To transmit data between the buoy and the cage, fast wireless communication is needed. To answer this problem, LoRa was used to overcome this. The results obtained were that LoRa was unable to carry out Multi Point to Point transmission, due to high delays and packet loss. Another solution used to answer this problem is using TCP-IP communication which is packaged in the ROS (Robot Operating System) workspace. This allows non-ROS devices such as the ESP32 to be connected to the ROS system on the laptop, the results obtained by the device on the buoy can send data faster than LoRa. This research indicates that LoRa cannot be effectively used for fast inter-device communication, as demonstrated by several experiments showing delays up to 100ms with LoRa, and doubling to around 200ms in the case of packet loss. LoRa is specifically designed for low-power, long-distance transmission. In contrast, TCP/IP communication is designed for fast wireless communication, achieving an average transmission delay of 11ms.
