Real time monitoring system for water pollution in Lake Toba

Lake Toba serves as an important tourism attraction in Indonesia, especially in the region of North Sumatera province. As tourism in Lake Toba develops, the possibility of environmental issues in Lake Toba, mainly water quality, is also increased. This condition increases necessity for a system that can monitor environment condition, especially water quality in Lake Toba. In this paper, we propose a design and development to gather and process data about water pollution in Lake Toba in a real-time process. Our proposed design consists of several sensors which record several parameters, such as Dissolved Oxygen Level, pH level, Water Temperature, Air Humidity and Air Temperature. These sensor buoys will be placed on several locations on Lake Toba's surface to increase the effectiveness of measurement, thus improving the measurement result. Finally, the real-time measured values from the sensors will be gathered and processed in one main controller; the experiment result shows that certain area can be monitored effectively.
