Abstract
Abstract This study aims to: (1) Design a digital electronics trainer along with a jobsheet on basic electrical and electronics subjects for class X students of Audio Video Engineering skill competency at SMK Negeri 1 Percut Sei Tuan; (2) Knowing the level of feasibility of digital electronics trainers in basic electrical and electronics subjects for class X students of Audio Video Engineering competency skills at SMK Negeri 1 Percut Sei Tuan; (3) Produce digital electronics trainers who can meet the requirements in basic electrical and electronics subjects for class X students of Audio Video Engineering skill competency at SMK Negeri 1 Percut Sei Tuan. The result of the research is a Digital Electronics Trainer consisting of a fiber PCB board, LED, Male Header, 220 resistor, a series of logic gates equipped with each IC, and using a Dip Switch. The results of the trainer requirements validation test by material experts amounted to 92.5% with the category of highly qualified; and the results of the validation test by experts obtained a score of 83.125% with a very decent category; User trials of 92.125% with a very decent category. Based on all the results of the study, it was concluded that the Digital Electronics Trainer was very suitable to be used as a learning medium for class X TAV at SMK Negeri 1 Percut Sei Tuan.
