Abstract

Individu dengan disabilitas, khususnya mereka yang mengalami gangguan pada pendengaran, menghadapi tantangan serius dalam aktivitas sehari-hari, khususnya dalam berkendara. Keterbatasan tersebut berpotensi untuk menghambat kemampuan komunikasi dan interaksi mereka dengan lingkungan sekitar, serta dapat menjadi penghalang dalam memperoleh izin mengemudi secara resmi. Guna mengatasi masalah tersebut, diusulkan sebuah penelitian terkait rancang modul alat asistif untuk membantu tunarungu dalam menerima pesan suara klakson yang ada pada situasi berkendara. Modul pelatihan yang diusulkan berfokus pada konversi suara klakson menjadi indikator getaran yang diletakkan pada steering wheel case untuk roda kemudi. Keluaran dari indikator terbagi ke dalam tiga level (Extremely Urgent, Urgent, dan Low Urgent) yang menunjukkan urgensi adanya suara klakson yang dipengaruhi oleh SPL dan jarak sumber suara ke klakson. Pengujian dilakukan dengan tiga variasi jarak yaitu 1 meter, 3 meter, dan 5 meter. Penentuan nilai threshold untuk ketiga level ditetapkan berdasarkan pembacaan nilai SPL klakson pada jarak yang diujikan dengan situasi penempatan sensor terpilih yaitu di dalam kendaraan Hasil pengujian menunjukkan kondisi sensor di dalam kendaraan memiliki angka redaman senilai 20 – 30 dB jika dibandingkan dengan SPL saat sensor diletakkan di luar kendaraan. Berdasarkan pertimbangan tersebut, terpilihlah nilai threshold untuk setiap level yaitu: Extremely Urgent dengan threshold 83 dB dengan duty cycle untuk getaran bernilai 100%, Urgent dengan threshold 65 dB dengan getaran 75%, dan Low Urgent dengan threshold 50 dB dengan getaran 50% dimana level tersebut menunjukkan perbedaan kekuatan yang dihasilkan oleh indikator getaran. Dalam uji coba bersama 5 subjek normal, rata-rata akurasi subjek berhasil menerima pesan sinyal suara klakson tanpa modul adalah 69,67%, sementara dengan modul safety drive training system mencapai 100%. Untuk meminimalkan kesalahan pembacaan SPL dan menambahkan kemampuan modul agar dapat digunakan di kondisi cuaca yang variatif, direferensikan penggunaan pemilihan sensor dan penggunaan modul ADC tambahan agar dapat membaca nilai SPL yang lebih presisi. Di samping itu, keterlibatan subjek tunarungu juga bisa dilakukan untuk melihat respon subjek secara langsung.

Individuals with disabilities, particularly those with hearing impairments, encounter significant challenges in everyday activities, notably in driving. These limitations impede their communication and interaction with the environment, creating obstacles to obtaining an official driving license. To address this, a study proposes the design of an assistive device module to aid the hearing impaired in receiving horn sounds during driving. The proposed training module converts horn sounds into vibration indicators on the steering wheel. The indicators output is categorized into three urgency levels (Extremely Urgent, Urgent, and Low Urgent), based on the Sound Pressure Level (SPL) and the distance of the horn sound source. Testing was conducted with three distance variations: 1 meter, 3 meters, and 5 meters. Threshold values for each urgency level were determined from SPL readings with the sensor placed inside the vehicle. Results indicated that sensor readings inside the vehicle showed a damping effect of 20-30 dB compared to readings outside the vehicle. Consequently, thresholds for the urgency levels were established as follows: Extremely Urgent at 83 dB with a 100% vibration duty cycle, Urgent at 65 dB with a 75% vibration duty cycle, and Low Urgent at 50 dB with a 50% vibration duty cycle. In trials involving five normal subjects, the average accuracy of horn sound signal reception without the module was 69.67%, whereas with the safety drive training system module, it achieved 100%. To minimize errors in SPL readings and enhance the module`s capability to be used in various weather conditions, it is recommended to use appropriate sensor selection and an additional ADC module for more precise SPL readings. Moreover, the involvement of hearing-impaired subjects is also crucial to directly observe their responses for further research development.
