ABSTRACT
Liquefied Petroleum Gas (LPG) is an alternative fuel in the form of gas that produces much fewer emissions than pollution produced by oil fuels. Therefore, on May 22, 2007, ESDM Minister Decree No: 1971/26/MEM/2007 was promulgated by implementing a program to convert fuels from kerosene to LPG. However, LPG has a greater risk of exploding than fuel oil, and many LPG cylinder explosions have occurred in Indonesia. Several security systems have been developed to address these issues, one of which is an LPG leak detection sensor. Arduino is a single, open-source microcontroller derived from a wiring-based platform. In this case, Arduino was used as a processing tool for supporting components of LPG leak detection and fire prevention devices. The author used the prototype development method. This study provided a solution to this problem by designing a gas leak detection device on an Arduino-based LPG tube using an MQ-2 sensor, as well as counteracting using a flame module equipped with a water pump in the event of a fire with a buzzer as a warning alarm and LCD for room monitoring. The detector for LPG leaks and fire prevention is expected to avoid fires caused by leaking LPG in the community.
