The Influence of Project-Based Learning (PjBL) on Students' Skills and Creativity in Drawing Network Installation Layouts at PTI UNDIKMA, Indonesia

Abstract

This study aims to explore the influence of Project-Based Learning (PjBL) on the material of drawing network installation layouts in the PTI Study Program at Mandalika University of Education (UNDIKMA). The research method employed was a one-group pretest-posttest design. The research subjects consisted of 30 PTI students. Data analysis techniques included descriptive data analysis for mean measurement and inferential statistics for testing the significance of the t-test values. The pretest scores for skills and creativity before using PjBL-based Learning were 45.33 and 43, respectively. Post-test scores for skills and creativity after using PjBL-based Learning in drawing network installation layouts were 85 and 85.83, respectively. The difference between pretest and post-test scores, referred to as the gain scores, for skills and creativity were 39 and 41, respectively, with N-gain indices of 0.7, categorised as high. Hypothesis testing using a paired sample t-test for skills and creativity resulted in a two-tailed t-value of 0.000, which is smaller than the alpha value of 0.05, indicating that Ha is accepted. This shows that Project-Based Learning (PjBL) can enhance students' skills and creativity in drawing layouts for the network installation course.
