Industrial waste is one of the causes of water pollution. Such waste requires periodic and continuous surveillance so that it can be followed up for specific treatments. This research develops LoRa (Long Range) technology for monitoring waste water based on geographic information system. Sensors used in this research are turbidity, pH, and temperature sensors. The result of this research is a system capable of displaying and mapping the conditions of waste water under surveillance. Alerts are generated when the quality of waste water reaches a threshold value set to the owner of the factory. The accuracy of the turbidity sensor under test is 93.42%.
