RANCANGAN PROTOTYPE AUTOMATIC EMERGENCY GATE PADA ACCESS ROAD BANDAR UDARA INTERNASIONAL JUANDA SIDOARJO

Keselamatan dan respons cepat terhadap keadaan darurat merupakan aspek vital dalam operasional bandar udara. Salah satu elemen pendukungnya adalah akses gerbang darurat (emergency gate) pada access road yang selama ini masih dioperasikan secara manual, sehingga berpotensi menimbulkan keterlambatan. Penelitian ini bertujuan untuk merancang dan merealisasikan sebuah Prototype Automatic Emergency Gate berbasis mikrokontroler Arduino Uno yang mampu beroperasi secara otomatis melalui sensor ultrasonik HC-SR04 serta kendali manual via modul Bluetooth HC-05. Sistem ini juga dilengkapi dengan tampilan LCD I2C dan indikator buzzer untuk mempermudah interaksi. Pengujian dilakukan terhadap kecepatan respon, jangkauan konektivitas Bluetooth, serta efektivitas sensor dalam mendeteksi objek. Hasil menunjukkan bahwa prototype bekerja secara responsif dan stabil hingga jarak 8 Meter tanpa halangan, serta mampu membuka dan menutup gerbang sesuai skenario darurat yang disimulasikan. Prototype ini diharapkan menjadi solusi awal untuk otomatisasi sistem akses darurat di bandara, sekaligus mendorong efisiensi dan peningkatan standar keselamatan operasional.

Safety and rapid emergency response are critical aspects of airport operations. One supporting element is the emergency gate on the access road, which is still commonly operated manually, potentially causing delays during emergency situations. This study aims to design and develop a prototype of an Automatic Emergency Gate based on the Arduino Uno microcontroller, capable of operating automatically via the HC-SR04 ultrasonic sensor and manually through the HC-05 Bluetooth module. The system is also equipped with an I2C LCD display and a buzzer indicator to enhance user interaction. Testing was conducted to evaluate response time, Bluetooth connectivity range, and the effectiveness of object detection. The results show that the prototype operates responsively and reliably up to a distance of 8 meters without obstacles and is able to open and close the gate according to simulated emergency scenarios. This prototype is expected to serve as an initial solution for automating emergency access systems at airports, thereby improving operational efficiency and safety standards.
