Abstract

Citra yang mengandung derau seringkali membatasi informasi berharga yang dibutuhkan untuk analisis citra. Restorasi citra mengacu pada pengapusan atau pengurangan degradasi citra yang dihasilkan dari proses pengambilan data atau proses akuisisi citra. Degradasi yang dimaksud meliputi derau error atau efek optik misalnya blur karena kamera yang tidak fokus atau karena goyangan kamera. Untuk menanggulangi hal tersebut, pada penelitian ini diimplementasikan restorasi citra dengan teknik secara spasial pada citra yang mengalami kerusakan akibat derau salt & pepper, derau gaussian dan derau speckle. Dari implementasi restotasi citra dan analisis pengujian MSE dan PSNR, citra derau gausssian dapat direstotasi filter median 5×5 dengan baik dan maksimal ditunjukkan dengan MSE 58,9 dan PSNR 101,23 sedangkan citra derau speckel kurang dapat direstorasi dengan filter rata-rata 3×3 yaitu dengan MSE 191,42 dan PSNR 80,75.

Abstract

This Microsoft Word optimization training aims to enhance the skills of teachers at Sekolah Dasar Negeri 2 Pampangan in utilizing information technology to support administrative tasks and learning. The activity was conducted offline in two main sessions: material delivery and practical simulations. The training material covered both basic and advanced features, such as mail merge, page layout, and document collaboration. A total of 30 participants attended the training and received direct guidance. Evaluation through questionnaires and observations showed that over 94% of participants understood and were able to apply the material effectively. This training proved to be effective in improving teachers' work efficiency and the quality of documents produced, as well as having a significant impact on increased productivity and professionalism in carrying out administrative tasks. Furthermore, the training strengthened teachers' digital literacy, accelerated technology adoption in learning, and supported their role as drivers of education in the digital era. However, limitations in equipment and basic computer skills remain challenges to be addressed in the future. This training provides an important contribution to strengthening teachers' digital literacy and improving the quality of education in elementary schools.
