Abstract
Visually impaired individuals often face mobility challenges, such as colliding with undetected objects or getting lost, even when using conventional white canes. This occurs due to the limitations of standard canes in detecting nearby obstacles, as well as environmental conditions that are not fully accessible—such as the absence of guiding paths. One such case was experienced by F, a visually impaired person who struggles to navigate their residential area due to the lack of specialized tactile pathways. With the advancement of technology, the use of the Arduino Uno R3 microcontroller and HC-SR04 ultrasonic sensor offers a potential solution to enhance the functionality of traditional canes. The sensor is designed to detect objects in front of, to the left, and to the right of the user. When an obstacle is detected, the sensor sends a signal to a buzzer, which emits an alert sound to inform the user so that the obstacle can be avoided. This research aims to: (1) design and develop a modified smart cane for the visually impaired using Arduino Uno and ultrasonic sensors; (2) understand the software development process on the Arduino Uno platform for the system; (3) determine the effectiveness of the tool in detecting environmental obstacles. The method used in this research is the Waterfall model, a systematic and sequential approach in system development that includes stages such as user requirement analysis, planning, modeling, construction, and system deployment, followed by maintenance and evaluation. Testing was carried out by involving four visually impaired respondents. The evaluation results, analyzed using a Likert scale-based assessment instrument, showed an average score of 0.8075, which falls under the “fairly valid” category according to the validity criteria. Therefore, it can be concluded that the modified smart cane for the visually impaired based on Arduino Uno and ultrasonic sensors is considered fairly effective for daily use. This device provides enhanced navigation support through obstacle detection, audible alerts via a buzzer, and tactile feedback through a vibration motor—contributing to increased safety and independence for visually impaired users.

| Additional Information: | Penyandang tunanetra sering kali menghadapi kendala dalam mobilitas, seperti menabrak objek yang tidak terdeteksi atau tersesat, meskipun telah menggunakan tongkat bantu konvensional. Hal ini terjadi karena keterbatasan tongkat dalam mendeteksi objek di sekitarnya, serta kondisi lingkungan yang belum sepenuhnya ramah bagi tunanetra, seperti kurangnya jalur pemandu. Salah satu contoh kasus dialami oleh F, seorang tunanetra yang kesulitan bernavigasi di lingkungan tempat tinggalnya karena area tersebut tidak sepenuhnya dilengkapi jalur khusus. Dengan kemajuan teknologi, pemanfaatan mikrokontroler Arduino Uno R3 dan sensor ultrasonik HC-SR04 dapat menjadi solusi untuk meningkatkan fungsi tongkat bantu tradisional. Sensor ini dirancang untuk mendeteksi objek di depan, kiri, dan kanan pengguna. Ketika terdapat hambatan, sensor akan mengirimkan sinyal ke buzzer untuk memberikan peringatan berupa suara, sehingga penyandang tunanetra dapat menghindari objek tersebut. Penelitian ini bertujuan untuk: (1) merancang bangun modifikasi tongkat bantu penyandang tunanetra berbasis Arduino Uno dan sensor ultrasonik; (2) mengetahui proses pengembangan perangkat lunak pada Arduino Uno; (3) menentukan tingkat keefektifan alat tersebut dalam mendeteksi hambatan di lingkungan sekitar. Metode yang digunakan dalam penelitian ini adalah metode Waterfall, yang merupakan pendekatan sistematis dan berurutan dalam pengembangan sistem, meliputi tahap: analisis kebutuhan, perencanaan, permodelan, konstruksi, hingga implementasi dan evaluasi sistem kepada pengguna. Pengujian dilakukan dengan melibatkan empat responden penyandang tunanetra. Hasil evaluasi menggunakan instrumen penilaian berbasis skala Likert menunjukkan bahwa nilai rata-rata yang diperoleh adalah 0,8075, yang termasuk dalam kategori “cukup valid” berdasarkan kriteria validitas. Dengan demikian, dapat disimpulkan bahwa modifikasi tongkat bantu penyandang tunanetra berbasis Arduino Uno dan sensor ultrasonik tergolong cukup efektif untuk digunakan dalam aktivitas sehari-hari. Alat ini memberikan dukungan navigasi tambahan melalui deteksi hambatan, sinyal peringatan suara (buzzer), dan getaran (vibration motor), yang mampu meningkatkan keamanan dan kemandirian pengguna tunanetra. | |||||||||
