Abstract
This study aims to develop and evaluate the feasibility level of a planetary type starter motor maintenance aids at the Light Vehicle Engineering’s expertise program in the Vocational High Schools (VHS). The research was conducted in Semarang Vocational High Schools. The study uses of development models consist of 4 stage (Four D) namely: Define, Design, Develop and Disseminate. This feasibility of props development results tested on media feasibility tests, material feasibility tests, test of improvement of learning outcomes between students whose learning is applied props with students who are not applied props and student responses to developed props. Analysis of media and material feasibility data using descriptive techniques, analysis of improved student learning outcomes using t-test tests that previously conducted normality tests, homogeneity tests. Based on the results of the study, props were declared eligible to be applied in vocational schools with an acquisition of 94.44% for media experts and 96.25% for material experts. Improved student learning outcomes from t-test results. The analysis of students' responses to props obtained by 87.60% was very well categorized.
Highlights
Education in Vocational High Schools (VHS) is an action that can not be separated from the process of teaching and learning activities
The development model in this study is 4-D. 4-D development model conducted through 4 stages, namely: Define, Design, Develop Development and Disseminate. This development model was chosen because as a reference and assessed in accordance with the characteristics of the product to be developed, namely LED-based props of planetary type starter motors, as well as 4-D research and development models in this study explaining the operational steps of development in detail and detail
Define, is the initial stage to establish a description of learning that is considered ideal by collecting various information related to learning media in the form of LED-based props starter motor planetary type developed and identify problems faced in learning that underlies the importance in developing LEDbased props on the competence of starter motor maintenance, especially planetary type
Summary
Education in Vocational High Schools (VHS) is an action that can not be separated from the process of teaching and learning activities. The purpose of learning is to achieve learning success, and for the process by which students acquire knowledge and develop potential (Dewantara et al, 2019). Learning is an activity designed and implemented systematically with procedures to achieve learning objectives by taking the best approach set by (Sutrisno & Siswanto, 2016). We can not be separated from the ability of teachers to choose the right and effective learning media. Teacher's ability to manage learning both in planning, implementing and evaluating the learning process and applying the right learning media effectively affects the student's learning success rate (Hadromi et al, 2021)
