Penelitian ini bertujuan untuk mengembangkan sistem deteksi kebocoran gas LPG menggunakan sensor MQ-5 dan mikrokontroler ESP8266. Sistem ini akan memberikan peringatan dini melalui smartphone dan buzzer serta secara otomatis menutup keran regulator gas saat mendeteksi kebocoran. Sistem ini juga menampilkan pemantauan langsung dengan IoT Blynk. Penelitian ini menggunakan metode eksperimental untuk menguji kinerja sistem yang dirancang. Tahapan penelitian mencakup desain perangkat keras dan perangkat lunak, perakitan perangkat keras, pemrograman perangkat lunak, pengumpulan data, dan diskusi hasil. Desain perangkat keras dan perangkat lunak dilakukan sesuai dengan spesifikasi alat dan bahan yang dibutuhkan. Penelitian ini berhasil mengembangkan sistem yang dapat mendeteksi kebocoran gas LPG dengan cepat dan efektif, dan secara otomatis mematikan regulator gas. Integrasi sensor MQ-5 dan mikrokontroler ESP8266 memungkinkan pemantauan dan notifikasi real-time melalui Blynk. Meskipun tidak melibatkan pengujian waktu, perbandingan alat, dan analisis kesalahan, hasilnya memberikan kontribusi signifikan terhadap pengembangan sistem keamanan gas LPG.

This research aims to develop an LPG gas leak detection system using the MQ-5 sensor and ESP8266 microcontroller. This system will provide early warning via smartphone and buzzer and automatically close the gas regulator tap when it detects a leak. and displays live monitoring with blynk iotThis research uses experimental methods to test the performance of the designed system. Research stages include hardware and software design, hardware assembly, software programming, data collection and discussion of results. Hardware and software design is carried out in accordance with the specifications of the tools and materials needed.This research aims to design a system using an ESP8266 microcontroller and MQ-5 sensor to detect LPG leaks. The system sends real-time data to a Blynk cloud server, allowing users to monitor LPG levels via a mobile app. It also includes a mechanical arm controlled by a servo to automatically shut off the gas flow when a leak is detected.This research successfully developed a system that detects LPG leaks quickly and effectively, and automatically shuts off the gas regulator. The integration of the MQ-5 sensor and ESP8266 microcontroller enables real-time monitoring and notifications through Blynk. Despite not involving time testing, tool comparison, and error analysis, the results contribute significantly to the development of LPG safety systems.
