RANCANG BANGUN MINI PROTOTYPE SISTEM EMERGENCY EXIT OTOMATIS BERBASIS ARDUINO PADA GEDUNG TERMINAL BANDAR UDARA

Sistem pintu darurat (emergency exit) eksisting di gedung terminal bandar udara masih menggunakan mekanisme manual pemecah kaca yang berisiko memicu penumpukan massa saat kondisi darurat. Penelitian Research and Development (R&D) dengan pendekatan ADDIE ini bertujuan melakukan rancang bangun purwarupa pintu darurat otomatis berbasis Arduino Uno yang terintegrasi prinsip fail-safe, sistem peringatan dini, dan data logger. Sistem memanfaatkan Sensor Suhu DHT22 sebagai pemicu otomatis, Push Button sebagai saklar manual, Solenoid Door Lock, Buzzer, modul SD Card, dan RTC DS3231. Hasil pengujian menunjukkan sistem merespons masukan manual dengan tingkat keberhasilan 100% (waktu respons 0,84 detik) dan otomatis membuka pengunci serta menyalakan alarm pada suhu ekstrem ≥ 60°C. SD Card dan RTC presisi merekam setiap aktivitas darurat secara real-time. Modul UPS Mini terbukti menopang daya mandiri tanpa jeda saat simulasi pemadaman listrik. Jaminan evakuasi berlapis sukses dibuktikan melalui mekanisme kelistrikan memotong (hardware bypass)dan tarikan mekanis (manual override) saat sistem diasumsikan mati total.

The existing manual emergency exit system at airport terminal buildings utilizes a break-glass mechanism, risking mass bottlenecks during emergencies. This Research and Development (R&D) study using the ADDIE approach aims to design and build an Arduino Uno-based automatic emergency exit prototype integrated with fail-safe principles, early warning systems, and a data logger. The system utilizes a DHT22 Temperature Sensor as an automatic trigger, a Push Button as a manual switch, a Solenoid Door Lock, a Buzzer, an SD Card module, and an RTC DS3231. Testing results demonstrate the system responds to manual input with a 100% success rate (0.84 seconds response time) and automatically opens the lock while triggering the alarm at extreme temperatures ≥ 60°C. The SD Card and RTC precisely log every emergency trigger in real-time. The Mini UPS module is proven capable of sustaining independent power without delay during a simulated power outage. Layered evacuation security is also successfully validated through a hardware bypass mechanism and a mechanical cable pull (manual override) when the system assumes a complete power failure.
