Indonesia is a maritime country with an area of water exceeding its land area. However, the abundance of resources in the Indonesian waters is not matched by the quality of the water. In order to continue to meet the need for water resources, various efforts have been made, including monitoring existing water resources. One method for monitoring the quality of water resources can be done by using various types of water pollution detection sensors. These sensors measure the level of water quality by putting it in the water. The sensors will generate temperature and humidity data in the environment around the water, the Total Dissolved Solids (TDS) value, and the turbidity value of water, the acidity and alkaline levels of the water, and measure the water temperature. The final objective of this research was to make a prototype of production-ready. Data from prototype measurement results can be integrated so that it can be monitored by central operators through water quality measurement results stored on the server. The system was used in floating net cages, therefore a feasible communication system with a wide coverage capability and minimum power consumption is needed. LoRa® (Long Range) was selected as the intermediary of the central operator's sensor and database. LoRa is a wireless communication based on IoT (Internet of Things) and works based on certain communication protocols with long-range capabilities in remote areas, low power consumption, size, level of design complexity, and low manufacturing costs. The test results showed that the system can communicate with a distance of 2 km with RSSI -111.
