The Effectiveness of Lean -Based Learning Model to Improve Work Skills of Vocational High School Students

Several studies have proven that the low work skills of graduates of Vocational High School (VHS) in mechanical engineering resulted in many problems in the world of work. The purpose of this research is to determine the effectiveness of the Lean manufacturing-based learning model to improve the work skills of mechanical engineering students in VHS. This study was categorized by experimental research that used the posttest-only control group design. The population of this study was the VHS students who joined an industrial internship course treated with a work shadowing strategy using  the Lean manufacturing-based learning model. There were thirty students chosen as the sample through the cluster random sampling technique. The data were collected by developing a test-performance. The data were analyzed with an independence t-test. Based on the research results, the application of the Lean manufacturing-based learning model showed better results than the conventional instruction model in the VHS of mechanical engineering. It can be concluded the Lean manufacturing-based learning model is one of the recommended alternatives to improve students' work skills of vocational high school students to fulfill the world of work demands.
