Penelitian ini bertujuan untuk mengetahui kelayakan trainer kit sensor fire fighting berbasis arduino uno yang meliputi validitas, kepraktisan, dan keefektifan di SMK Negeri 2 Bojonegoro.

           Pengembangan trainer dan jobsheet ini menggunakan model pengembangan Research and Development (R&D). Desain penelitian yang digunakan yaitu One-Shot Case Study. Ujicoba trainer dan jobsheet dilakukan pada peserta didik kelas XII TEI SMK Negeri 2 Bojonegoro Sebanyak 30 peserta didik. Instrument yang digunakan yaitu lembar validasi trainer dan jobsheet, angket kepraktisan trainer dan jobsheet, dan lembar penilaian peserta didik.

             Hasil penelitian menunjukkan kevalidan dan dinyatakan sangat valid untuk digunakan dengan hasil persentase trainer sebesar 89,58% dan jobsheet sebesar 86,22%. Untuk keefektifan trainer dan jobsheet dapat dikatakan efektif, hasil belajar siswa ranah kognitif mendapat nilai rerata 81,66. Pada ranah psikomotor mendapat nilai rerata 81,83, serta nilai akhir belajar dengan rerata 81,78 dengan nilai t_hitung sebesar 9,211 dengan df adalah 29 dan memperoleh signifikansi 0,000. Sedangkan untuk kepraktisan dinyatakan sangat praktis dengan persentase respon siswa sebesar 88,11%. Berdasarkan hasil tersebut, maka penelitian ini menghasilkan trainer dan jobsheet yang layak meliputi validitas, kepraktisan, dan keefektifan.

        This study aims to determine the feasibility of an arduino-based goods sorting conveyor trainer which includes validity, practicality, and effectiveness in SMK 2 Bojonegoro.

The development of this trainer and jobsheet uses the Research and Development (R & D) development model. The research design used is the One-Shot Case Study. The trainer and jobsheet trials were conducted on students of Class XII TEI of SMK Negeri 2 Bojonegoro as many as 30 students. The instruments used were validation sheets for trainers and jobsheets, practicality questionnaires for trainers and jobsheets, and student assessment sheets.

The results showed that validity was declared to be very valid for use with a percentage of trainer percentage of 89.58% and jobsheet of 86.22%. For the effectiveness of trainers and jobsheets can be said to be effective, student learning outcomes in the cognitive domain get an average value of 81.66. In the psychomotor domain, the mean score was 81.83, and the final learning value was 81.78 with a t_count of 9.221 with df was 29 and obtained a significance of 0.000. Whereas for practicality it is stated to be very practical with a percentage of student responses of 88.11%. Based on these results, this study produced decent trainers and jobsheets including validity, practicality and effectiveness.
