Efektivitas Penggunaan Media Video dalam Pengembangan Bahan Pelatihan Dasar Soldering di PT XYZ

Abstract

PT XYZ faces challenges in improving the quality of basic soldering training for manual operators. This study aims to develop and evaluate the effectiveness of video media as a basic soldering training material. Using the Research and Development (R&D) method with the 4D development model (Define, Design, Develop, Disseminate), this study involved 30 training participants. The validation result showed excellent feasibility ratings from media experts (92%) and material experts (94%). Effectiveness testing was conducted using a quasi-experimental design with a one-group pretest-posttest approach. Data analysis using the Shapiro-Wilk test showed normal distribution with significance values of 0.058 for pretest and 0.017 for posttest. Paired t-test results revealed a significant improvement between pretest (63.0) and posttest (80.3) mean scores with a significance value of <0.001 (p<0.05). This study concludes that the use of video media is effective in enhancing trainees understanding of manual soldering standard procedures at PT XYZ.
