PENGARUH OPTICAL CHARACTER RECOGNITION (OCR) TERHADAP KEMAMPUAN MEMINDAI OBJEK VISUAL PADA SISWA TUNANETRA DI SLBN CERME

THE INFLUENCE OF OPTICAL CHARACTER RECOGNITION (OCR) ON THE ABILITY TO SCAN VISUAL OBJECTS IN BLIND STUDENTS AT SLBN CERME

Teknologi asistif memberikan solusi sebagai alat bantu untuk manusia. Salah satunya yaitu optical character recognition untuk tunanetra. Penelitian ini di latar belakangi oleh kendala Siswa Tunanetra di SLBN Cerme dalam hal memindai objek visual seperti warna, kondisi lingkungan, tulisan cetak dan tulisan tangan, mata uang, dan file gambar yang butuh di deskripsikan. Ketika di tanya tentang aplikasi pemindai objek visual untuk Tunanetra, mereka belum pernah memakai fasilitas tersebut dan baru bisa mengoperasikan pembaca layar yang ada di smartphone merekasehingga dibutuhkan pelatihaan menggunakan OCR. Tujuan dari penelitian ini yaitu untuk membuktikan pengaruh optical character recognition (OCR) terhadap kemampuan memindai objek visual pada siswa tunanetra di SLBN Cerme. Penelitian ini menggunakan pendekatan kuantitatif eksperimen dengan desain penelitian pre eksperimental one group pretest-postest. Subjek penelitian di ambil menggunakan purposive sampling yang melibatkan 6 siswa tunanetra dengan persyaratan mampu mengoperasikan pembaca layar di smartphone dan berkendala mengidentifikasi objek visual. Instrumen menggunakan tes dan observasi. Hasil analisis penelitian menggunakan statistik non-parametrik dengan uji Wilcoxon bertaraf nyata 5%, Wilcoxon menunjukkan hasil pretest dan posttest harian mengalami pengaruh sebesar 0,026, dan pretest-postest observasi mendapatkan 0,042, rata-rata keseluruhan mendapatkan 0,034 dengan signifikansi lebih kecil dari 0,05. Disimpulkan bahwa terdapat pengaruh yang signifikan terkait optical character recognition terhadap kemampuan memindai objek visual siswa tunanetra di SLBN Cerme.

Assistive technology provides solutions as a tool for humans. One of them is optical character recognition for the blind. This research was motivated by the obstacles faced by Blind Students at SLBN Cerme in scanning visual objects such as colors, environmental conditions, printed and handwritten writing, currency, and image files that needed to be described. When asked about a visual object scanner application for the blind, they had never used this facility and had only been able to operate the screen reader on their smartphone, so training in using OCR was needed. The aim of this research is to prove the effect of optical character recognition (OCR) on the ability to scan visual objects in blind students at SLBN Cerme. This research uses a quantitative experimental approach with a pre-experimental research design, one group pretest-posttest. Research subjects were taken using purposive sampling involving 6 blind students who were required to be able to operate a screen reader on a smartphone and had problems identifying visual objects. The instrument uses tests and observations. The results of the research analysis used non-parametric statistics with the Wilcoxon test with a significance level of 5%. Wilcoxon showed that the results of the daily pretest and posttest had an influence of 0.026, and the pretest-posttest observation obtained 0.042, the overall average was 0.034 with a significance of less than 0.05. It was concluded that there was a significant influence regarding optical character recognition on the ability to scan visual objects of blind students at SLBN Cerme.
