Abstract

Keterbatasan akses terhadap informasi tertulis masih menjadi hambatan utama bagi penyandang tunanetra dalam meningkatkan kemandirian literasi. Braille yang tersedia masih memiliki keterbatasan dalam hal biaya produksi dan ketersediaan bahan bacaan. Penelitian dilakukan untuk mengembangkan dan menguji prototipe alat bantu baca buku portabel berbasis Optical Character Recognition (OCR) dengan kontrol full cycle (mulai, ulang, berhenti) untuk membantu penyandang tunanetra membaca buku cetak secara mandiri. Metode pengembangan yang digunakan adalah Research and Development (R&D) dengan model pengembangan V. Prototipe dikembangkan menggunakan Raspberry Pi Zero W sebagai pusat pengendali yang terintegrasi dengan modul kamera, sensor ultrasonik HC-SR04 untuk optimalisasi jarak, sensor LDR serta LED untuk pencahayaan otomatis, sistem identifikasi objek, dan earphone bluetooth untuk output suara berbasis Text to Speech (TTS). Hasil pengujian menunjukkan bahwa prototipe mampu mengintegrasikan sistem OCR dan TTS dengan tingkat akurasi pembacaan sebesar 100% pada jenis font Arial, Times New Roman, dan Helvetica. Sistem juga mampu mengidentifikasi objek buku dan bukan buku dari jarak 30 cm sampai dengan 45 cm dan mengaktifkan LED secara otomatis berdasarkan nilai resistansi LDR yaitu melebihi 9.000 Ω. ***** Limited access to written information remains a major barrier for individuals with visual impairments in achieving literacy independence. Existing Braille media still face limitations in terms of production costs and the availability of reading materials. This study was conducted to develop and evaluate a portable book-reading assistive device based on Optical Character Recognition (OCR) with full-cycle control (start, rewind, and stop) to enable individuals with visual impairments to read printed text book independently. The development method employed was Research and Development (R&D) using the V-Model development approach. The prototype was developed using a Raspberry Pi Zero W as the main controller, integrated with a camera module, an HC-SR04 ultrasonic sensor for reading distance optimization, an LDR sensor and LED for automatic lighting control, an object identification system, and a Bluetooth earphone to provide Text to Speech (TTS) audio output. The test results demonstrated that the prototype successfully integrated the OCR and TTS systems, achieving a reading accuracy of 100% for Arial, Times New Roman, and Helvetica fonts. In addition, the system was able to distinguish books from non-book objects at distances ranging from 30 cm to 45 cm and automatically activate the LED when the LDR sensor resistance exceeded 9,000 Ω.
