The Development of Tungsten Inert Gas Welding Practical Manual for Vocational High School

Abstract This study aims to develop a product in the form of a tungsten inert gas (TIG) welding practice manual for Class XII students and find out the level of the eligibility. This research is a type of Research and Development (R&D) research. The stages of this research include problem identification, data collection, product design, design validation, design revision, limited trial, product revision I, large group trial, product revision 2, product ready to use. Data collection techniques are done using a questionnaire. The data obtained were analyzed using quantitative descriptive analysis techniques. The results of this study are in the form of a TIG welding practice manual for class XII students. The feasibility level of the TIG welding practice manual is known through the validation process carried out by 4 expert validators. The feasibility test was conducted on 30 students. The average feasibility value obtained from experts as well as the feasibility test on students was 84.81% and included in the very feasible category.
