Health is a physical condition of a person running well and normally. Health can be influenced by internal and external factors. Water is an external factor that can affect health, therefore water sources for human must be clean from the dangers of bacteria, microorganisms, heavy metals, the level of acidity, and also the standard ph. Therefore the design of turbid water filters uses the HC-05 module as a tool to control the prototype to improve water quality in the school, namely SDN 011 TANJUNGPINANG TIMUR. This innovation is useful to prevent water users from being infected by various diseases. The water filtration process has several stages, HC-05 module will receive data from android to turn on the water pump, then the water pump will transfer water to filter to filter impurities, the filtering results will be fed to the water source too, green LED lights as an indicator of the filtration process is running, and uses a red LED light as a tool indicator is not operating. In addition to this simple innovation also has power because it uses very low electrical energy so it is more energy efficient, besides that this innovation is very useful to purify water so that users of water in the surrounding environment no doubt in using water.
