Design and Implementation Supervisory Control and Data Acquisition (SCADA) of Flocculation Process of Water Treatment Plant (WTP) Using Raspberry Pi

Water is a very important factor for human survival, in order to get good quality water for daily activity, we need to do Water Treatment Plant (WTP). WTP can be treat the raw water from rivers, lakes, reservoirs or other underground sources to be drinkable or clean water that can be used by humans. Flocculation process is very important in WTP because water that processed was coming from the river and reservoir which has percentage of turbidity. SCADA system is used on flocculation process to ease the process of monitoring, so it can improve water quality produced. Raspberry Pi 3 B is used as an effective alternative to replace Programmable Logic Control (PLC) on flocculation process. Turbidity Sensor as an indicator of turbidity that produced in flocculation process. Input the water before mixing on the system varied into 3 samples are 33 NTU, 21 NTU and 16 NTU. While output after mixing has average value 13,54 NTU, 10,17 NTU and 8,16 NTU. The output is still suitable with a parameter. All that SCADA system elements are well operated at flocculation process on Water Treatment Plant (WTP).
