The development of the industrial era 4.0 requires Vocational High School (SMK) students to have digital literacy skills that are not only consumptive, but also productive and applicable. However, conditions in the field show that most students still have limitations in understanding programming, digital literacy, and the use of interactive technology. Therefore, this community service activity aims to improve the digital literacy of SMK Muhammadiyah Bumiayu students through Kodular-based programming training with Edu-QR Code integration. The method used is a practice-based training approach (hands-on learning) and project-based learning implemented through several stages, namely preparation, socialization, programming training, product development, evaluation and mentoring, and dissemination. Evaluation was carried out through pre-tests and post-tests to measure the improvement of students' digital literacy. The results of the activity showed a significant increase in all aspects of digital literacy, with the highest increase in the ability to use Kodular and utilize Edu-QR Codes. In addition, students succeeded in producing innovative, interactive, and applicable digital application products. This activity also has an impact on increasing students' motivation, creativity, and problem-solving abilities in technology development. Thus, Kodular-based programming training integrated with Edu-QR Code has proven effective in improving digital literacy of vocational school students and supporting the development of 21st-century competencies that are relevant to the needs of the world of work.
