Abstract
PT Petrokimia Gresik memiliki risiko kebakaran pada ruang Sub Station akibat korsleting pada panel listrik, sementara pengawasan operator tidak berlangsung secara terus-menerus. Penelitian ini merancang dan merealisasikan sistem proteksi kebakaran berbasis Internet of Things (IoT) dengan Automatic Fire Suppression System untuk panel box elektrik. Sistem menggunakan sensor DS18B20, sensor asap MQ-7, dan flame sensor sebagai pendeteksi dini, serta STM32 sebagai pengolah data dan ESP8266 sebagai modul komunikasi. Data pembacaan ditampilkan secara real-time pada website untuk keperluan monitoring dan pelaporan. Hasil validasi menunjukkan sensor DS18B20 memiliki akurasi sebesar 93,04%, sementara sensor asap MQ-7 memiliki akurasi 83,29%. Pada uji coba sistem, sensor MQ-7 mampu mendeteksi asap hasil pembakaran kertas hingga melewati set point 500 ppm dan memicu notifikasi peringatan ke website secara otomatis. Flame sensor mendeteksi api dan mengaktifkan relay untuk membuka solenoid valve sehingga gas CO₂ dikeluarkan sebagai media pemadam, dan pemadaman berhasil dilakukan secara otomatis. Sistem juga mampu mengirimkan data dan notifikasi secara real-time, serta melakukan proses pemadaman tanpa merusak komponen panel karena penggunaan media CO₂ sesuai standar NFPA 12 dan SNI 03-3985-2000. Berdasarkan hasil tersebut, sistem terbukti mampu melakukan deteksi dini, memberikan peringatan, serta melakukan pemadaman otomatis pada panel box listrik. Sistem ini diharapkan dapat meningkatkan keselamatan operasional, mempercepat respon Emergency Response Team, dan meminimalisir risiko kerusakan aset akibat kebakaran.

PT Petrokimia Gresik operates continuously and presents a high fire risk in the Sub Station room due to electrical panel short circuits without continuous operator supervision. This research designs and implements an Internet of Things (IoT)-based fire protection system equipped with an Automatic Fire Suppression System for electrical panel boxes. The system employs DS18B20 temperature sensors, MQ-7 smoke sensors, and flame sensors as early fire detection devices. Sensor data are processed by an STM32 microcontroller and transmitted via ESP8266 for real time monitoring and reporting through a web interface. Validation results show that the DS18B20 temperature sensor achieves an accuracy of 93.04%, while the MQ 7 smoke sensor achieves 83.29%. System testing demonstrates that the MQ 7 successfully detects smoke concentrations above the 500 ppm set point and triggers an automatic warning notification. When flame is detected, the system activates a solenoid valve to discharge CO₂ as the extinguishing agent, successfully performing automatic suppression without damaging electrical components. The system also provides real time data archiving for audit and emergency response support. Based on these results, the system is proven capable of early detection, automatic warning, and autonomous suppression, thereby improving operational safety and reducing fire-related asset damage risks.
