Abstract

Penelitian ini bertujuan mengembangkan media pembelajaran interaktif berbasis YouTube bernama MUNEMA (Mudah Nembang Macapat) untuk meningkatkan keterampilan siswa dalam melagukan tembang macapat di SD Negeri 2 Trayu, Kendal. Metode penelitian yang digunakan adalah Research and Development (R&D) dengan model pengembangan Borg & Gall. Subjek penelitian adalah 16 siswa kelas IV. Instrumen penelitian meliputi angket, observasi, wawancara, dokumentasi, dan tes pretest–posttest. Hasil validasi oleh ahli materi dan media menunjukkan kelayakan sangat tinggi, masing-masing 94,5% dan 91,6%. Uji coba kelompok kecil dan besar menunjukkan peningkatan nilai siswa yang signifikan, dengan nilai rata-rata pretest 38,34 meningkat menjadi 81,67, serta dari 32,81 menjadi 76,56. Hasil uji paired sample t-test menunjukkan signifikansi 0,001, sementara analisis N-Gain sebesar 0,7043 (kategori tinggi) dan 0,6504 (kategori sedang), menunjukkan bahwa media efektif dalam meningkatkan hasil belajar. Media ini juga mendapatkan tanggapan sangat positif dari siswa dan guru. Media MUNEMA berpotensi digunakan secara lebih luas sebagai alternatif pembelajaran seni berbasis budaya lokal yang menarik, mudah diakses, dan mampu meningkatkan partisipasi serta hasil belajar siswa, terutama dalam konteks pembelajaran tembang macapat di sekolah dasar.

Abstract

This study compares the simulation results of a CNC lathe program with the actual production results of a CNC lathe. CNC lathes are used in the manufacturing of precision components for various industrial applications. Simulation of CNC lathe programs can provide an accurate estimate of the production output before the actual production process begins. In this study, we compared dimensional tolerance, geometric accuracy, and surface quality between simulated and actual results. The simulation method used is 2D modeling which involves the calculation of tool trajectories and cutting parameters inputted into the simulation panel. Actual production data was obtained from the measurement of components produced from the CNC lathe. A comparative analysis was conducted to evaluate the extent to which the simulation can predict the actual production results. The results show that, although the simulation can give a good picture, there is still a significant difference between the simulation results and actual production. The findings have practical implications in improving efficiency and accuracy in the planning and production process using CNC lathes.
