LPG is prone to fire due to the high pressure in the air. Microcontroller-based tools have been widely used to solve the problem of LPG leakage. The LPG safety system in Boak Village uses a built-in device from a conventional regulator which is manually rotated to shut off the LPG flow, this is less effective because users cannot know the condition of LPG when outside the house. This study designs an LPG leak detector based on the Wemos D1 R1 microcontroller with a calling notification feature. The result of the research is 95% of respondents agree that the tool needs to be made, with the finding that the LM2596 Step down voltage is unstable from 4.12V to 3.5V. The product revision added a 1000mF capacitor and an LED as a leakage indicator, as well as a resistor as an LED voltage blocker. This tool has been functioning optimally because it has been tested and refined based on the findings. It is hoped that this tool will serve as an early warning system for LPG leaks.Keywords: Detection Tool, Liquefied Petroleum Gas, Microcontroller, Call Notification, Wemos D1 R1

Indonesian people already use LPG (Liquefied Petroleum Gas) as the main fuel. LPG has a weakness in the material used is very flammable in air. LPG safety devices are currently ineffective because we cannot know the condition of LPG when we are not at home. The Research and Development method is able to produce and develop products that already exist today and have a high validity value, because they have passed various series of trials. This study develops an LPG leak detector using research and development methods. The result of this study is that the LPG leak detection tool has a call gateway notification feature on two user mobile numbers that have been setup on the microcontroller and have been tested using gas from matches and smoke. The limited test obtained an average score of 80 and is included in the good category, while the wider trial of the developed tool has proven to be more effective than the manual tool currently used. This gas leak detection tool is expected to be able to make it easier for the public to get early notification when an LPG leak occurs and immediately take preventive actions to prevent fires.
