Abstract

Abstrak : 

Penelitian ini bertujuan merancang dan mengembangkan sistem starter interlock kendaraan berbasis deteksi alkohol dan pemantauan Internet of Things (IoT) secara real-time untuk mengurangi risiko kecelakaan akibat pengemudi di bawah pengaruh alkohol. Metode yang digunakan adalah Research and Development (R&D) yang meliputi perancangan, pengembangan, dan pengujian sistem. Sistem menggunakan ESP32, sensor MQ-3, sensor DHT22, dan relay yang terintegrasi dengan notifikasi Telegram. Hasil pengujian menunjukkan sistem mampu mendeteksi alkohol mulai dari konsentrasi 10% pada jarak deteksi 5 cm, dengan rata-rata error 2,10% dan waktu respons 10 detik. Pengujian menggunakan sampel alkohol berkonsentrasi 21,6% dan 30% menunjukkan sistem secara konsisten mencegah kendaraan dioperasikan dengan mempertahankan relay pada kondisi OFF. Sistem juga menyediakan autentikasi token sebagai mekanisme alternatif sehingga berpotensi meningkatkan keselamatan berkendara.

Abstract : 

This research aims to design and develop a vehicle starter interlock system based on alcohol detection and real-time Internet of Things (IoT) monitoring to reduce the risk of traffic accidents caused by drivers under the influence of alcohol. The research employed the Research and Development (R&D) method, including system design, development, and testing. The system utilizes an ESP32, an MQ-3 sensor, a DHT22 sensor, and a relay integrated with Telegram notifications. Experimental results show that the system detects alcohol starting from a 10% concentration at a detection distance of 5 cm, with an average error of 2.10% and a response time of 10 seconds. Tests using 21.6% and 30% alcohol samples consistently prevented vehicle operation by keeping the relay OFF. The proposed system demonstrates the potential to improve driving safety through early alcohol detection and automatic vehicle interlock.
