Liquid Petroleum Gas (LPG) which has components in the form of propane and butane currently has an important role for people in the household and industry. However, there are things that must be considered when using LPG in terms of safety. This is because the gas is volatile and there is a possibility of leaking which will be very prone to cause explosion or fire hazard. The gas leak early detection device is a very appropriate effort in dealing with early detection of LPG leak in order to minimize the occurrence. This study was designed using a prototype system that functions as a simulation if there is a gas leak in a room by using the MQ-6 sensor which detects LPG content in the room. The way this tool works is that, if there is a gas leak, the MQ-6 sensor will detect it and then send the data to the microcontroller on Arduino in the form of analog data. In the MQ-6 sensor-based LPG leak early detection system using Arduino it has been successfully running according to an algorithm that has been designed and installed before in the test results, and send a warning message to the specified number. This system can detect gas faster in a closed room, on the contrary if in an open room the sensor can detect longer because the level of contaminated gas will be immediately wasted into the air.
