Abstract

The motivation behind this study was the observed lack of effectiveness of lathe machining learning at SMK Negeri 13 Surabaya, which was influenced by limited facilities and learning methods that did not fully engage students actively. This study aims to examine the implementation of the peer teaching method in improving the competence of Grade XI Mechanical Engineering students. This research was designed using a Classroom Action Research (CAR) approach and was carried out in two cycles. The research subjects were Grade XI Mechanical Engineering students. Data collection techniques included written tests to measure the knowledge aspect. The research instruments consisted of multiple-choice and essay questions. The analysis of the data was conducted using a descriptive quantitative technique to measure the improvement in students' learning outcomes from pre-test to post-test. The findings of this study indicate that the peer teaching method can be effectively applied to enhance students' competence. A resutlt after test showed an N-gain score of 0.445, categorized as moderate, with a classical mastery learning rate of 93% in the post-test.
