Abstract

The body electricity course is a compulsory subject so it is necessary to innovate teaching materials to achieve learning goals. This study aims to (1) determine the validity of interactive textbooks based on qr code and short links in body electricity courses, (2) find out the practicality of using interactive textbooks based on QR code and short links in body electricity courses, and (3) find out the effectiveness of interactive textbooks based on QR codes and short links in body electricity courses. This research is R&D. The model used is 4D but only the define, design, and develop stages are carried out. The questionnaire uses 7 Likert scales. The research instrument proved its validity and reliability. The results of this study indicate that (1) interactive textbooks based on QR code and short links in body electricity courses from material experts while media experts are very valid at 94.63% and 95.39%, (2) interactive textbooks interactive textbooks based on QR code and short links in body electricity courses are very practical by 86.61%, and (3) interactive textbooks based on QR code and short links on body electricity courses are very effective by 86.43%. Based on the results of this study, it can be interpreted that the textbooks developed are feasible to be implemented in learning and disseminated.

Abstract

This community service program aimed to improve vocational students’ competence in metal casting by introducing LPG-fueled furnaces and UNNES crucibles fabricated from evaporation boat waste. The partner, SMK Negeri 2 Kudus, faced two main challenges: limited utilization of aluminum scrap from automotive practice and the absence of affordable, durable crucibles for repeated casting activities. The program applied a structured approach consisting of socialization, training, mentoring, and evaluation. Activities included theoretical instruction, pretest–posttest assessment, and hands-on workshops involving furnace operation, crucible utilization, mold preparation, and aluminum casting. Results demonstrated significant improvements: the average pretest score of 4.85 increased to 9.0 in the posttest, reflecting an 85.57% gain in competence. Qualitative observations showed that students developed greater confidence, teamwork, and adherence to safety standards. Beyond competence improvement, the innovation provided a cost-effective and sustainable solution for recycling aluminum scrap and reducing dependence on expensive imported crucibles. The program effectively integrated research-based technology into vocational education and aligned with the Teaching Factory model. This collaboration between university and school can serve as a replicable model for other vocational institutions seeking to strengthen practical skills, sustainability, and industry relevance.
