Interference that occurs can be of various kinds, including spikes or drops in electric voltage (over / under voltage) and voltage instability. Currently, there is an incident of someone wanting to repair the cable damage to the roof of a lightweight steel construction house which caused someone to die from being electrocuted by an electric current flowing in mild steel. To solve this problem, in this final project, a prototype tool that is capable of detecting electric leaks on the roof of a lightweight steel construction house is made. This tool works when the Voltage sensor detects the Voltage ? 180 & ? 183 then it is declared that there is no Voltage when the light is on, if a Voltage is detected other than ? 180 & ? 183 then it is declared that there is a Voltage at the time In this condition, the Relay is active and the Buzzer is alive as an alarm warning of an electric leak in mild steel construction. When testing the sensor Voltage output ZMPT101B ? 180 & ? 183, the measurement Voltage is 0 Volts. When testing the ZMPT101B sensor Voltage output other than ? 180 & ? 183, the measurement Voltage is 228 Volt.} }
