The Indonesian people as users of LPG gas cylinders are increasing from year to year. This situationoccurs because of the implementation of a government program, namely the conversion of kerosene toLPG gas with the aim of diverting subsidies and the use of kerosene to gas. Users of LPG gas cylindersare not only limited to urban communities, but now they have penetrated into remote areas of thecountryside. The LPG gas cylinders that are most widely used by the community are those measuring 3Kg and 12 Kg. Because the price is affordable and relatively easy to find in residential areas. The manyrisks of gas leaks in the community make people nervous, therefore people need a tool that can provideearly warning if a gas leak occurs. This gas leak detector uses the MQ2 gas sensor as a gas substancedetector and the Arduino Uno as a processing tool. This tool will provide information in the form ofsound and warning lights, as for prevention by using a fan that functions to remove gaseous substances inthe room. This tool is designed to detect gas leaks in the room.
