Abstract

Gambar adalah salah satu komponen multimedia dalam bentuk informasi visual. Gambar yang buram atau mengalami degradasi kualitas sering kali menghambat proses analisis dan interpretasi data visual. Pengolahan Citra Digital adalah cabang ilmu yang mempelajari cara membentuk, memproses, dan menganalisis citra untuk menghasilkan informasi yang dapat dimengerti dan dimanfaatkan oleh manusia. Pemulihan gambar merupakan teknik yang bertujuan menghilangkan blur atau noise dari suatu gambar. SSIM digunakan untuk mengevaluasi efektivitas metode reduksi noise yang diusulkan. MATLAB dan Octave merupakan perangkat lunak yang umum digunakan dalam pemrosesan citra karena memiliki pustaka dan fungsi yang mendukung operasi konvolusi, filtering, dan deblurring. Metode penelitian mencakup unsharp masking, histogram equalization, dan median filter. Hasil penelitian mencakup hasil kode program dari metode penelitian sebelumnya dan perhitungan PSNR, MSE, dan MSE. Penelitian ini telah mengimplementasikan tiga metode  pemrosesan citra digital Unsharp Masking, Histogram Equalization, dan Median Filter dalam aplikasi berbasis GNU Octave untuk memperbaiki kualitas gambar buram

Abstract

This study aims to describe the improvement of student learning outcomes in integrated thematic learning using the Problem Based Learning Model in class IV of 15 Koto Tangah Elementary School, Agam Regency. This type of research is a classroom action research using qualitative and quantitative approaches. The research subjects were teachers and fourth grade students as many as 21 students. The results of the observation of the learning plan in the first cycle were 80.55%, and the second cycle was 94.44%. Teacher observations in cycle I were 78.12 and cycle II 93.75. While the improvement of student aspects in the first cycle was 82.81 and the second cycle was 93.75. While the average student learning outcomes in the knowledge aspect were 74.05 to 84.28, and in the skills aspect the average got 76.97 to 83.92. Keywords: problem based learning, learning outcomes, integrated thematic learning.
