This study aims to develop learning media in the form of a digital electronics trainer kit to improve understanding of the basic concepts of electricity and electronics, especially class X students majoring in Industrial Electronics at SMKN 8 Tangerang City. to answer the problem of students' knowledge in recognizing components in learning the elements of the basic concepts of electricity and electronics is not optimal because students are not introduced and get practice using hardware or props directly and because the practical learning process is limited to using only the teacher's laptop, learning takes a long time. This research uses the Research and Development (R&D) method with the 4-D development model which includes defining, designing, developing, and disseminating stages. Data was collected through interviews, questionnaires, media and material expert validation using Aiken's V formula to measure the content validity of the instrument. The validation results showed an average Aiken's V value of 0.948 for the media and 0.944 for the material, both of which were included in the “very valid” category. The media feasibility test by experts obtained an average score of 138.3, while the material feasibility by experts gave an average score of 99.6. Student respondents gave an average score of 68.5 out of a total score of 2057, which indicates the media is in the “very feasible” category. These findings indicate that the trainer kit developed is effective in increasing learner engagement and understanding in a practical and contextual manner. date: 2025 type: Thesis type: NonPeerReviewed format: text language: id identifier: https://eprints.untirta.ac.id/48499/6/FADEL%20MONTOYA_2283210022_FULL%20TEXT.pdf format: text language: id identifier: https://eprints.untirta.ac.id/48499/1/FADEL%20MONTOYA_2283210022_01.pdf format: text language: id identifier: https://eprints.untirta.ac.id/48499/2/FADEL%20MONTOYA_2283210022_02.pdf format: text language: id identifier: https://eprints.untirta.ac.id/48499/3/FADEL%20MONTOYA_2283210022_03.pdf format: text language: id identifier: https://eprints.untirta.ac.id/48499/5/FADEL%20MONTOYA_2283210022_04.pdf format: text language: id identifier: https://eprints.untirta.ac.id/48499/4/FADEL%20MONTOYA_2283210022_05.pdf format: text language: id identifier: https://eprints.untirta.ac.id/48499/7/FADEL%20MONTOYA_2283210022_REFF.pdf format: text language: id identifier: https://eprints.untirta.ac.id/48499/9/FADEL%20MONTOYA_2283210022_LAMP.pdf format: text language: id identifier: https://eprints.untirta.ac.id/48499/8/FADEL%20MONTOYA_2283210022_CP.pdf identifier: MONTOYA, FADEL (2025) PENGEMBANGAN TRAINER KIT ELEKTRONIKA DIGITAL SEBAGAI MEDIA PEMBELAJARAN KONSEP DASAR KELISTRIKAN DAN ELEKTRONIKA DI SEKOLAH MENENGAH KEJURUAN.
