River Water Pollution Monitoring using Multiple Sensor System of WSNs (Case: Siak River, Indonesia)

The river is a natural phenomenon that commonly available in the tropical region because of rain intensity. Many peoples and community like to live along the riverside for a few decades ago. The river used by the community for transportation and daily activities uses river water. In this research objective to design and develop a new system with multiple sensors system to monitor river water pollution because most of the people use it. Wireless Sensor Networks (WSNs) used in this design and development because of advantages WSNs system, multiple sensor nodes installed for detection of water pollution such as water temperature, pH, electrical conductivity (EC) and dissolved oxygen (DO). The system designed to be able to monitor river water pollution parameters and send the information to the data center (backend system). Arduino microcontroller used to process and filtering the data before sending to the backend system, only valid and valuable information to collect and keep in the database. Results show system be able to detect polluted water with indicating parameters and shows in a graph. Based on analysis can be concluded that polluted water indicator mostly from residence waste and industry. Furthermore, WSNs sensors will deploy in some area then compare the results each other.
