PENGEMBANGAN MODUL AJAR BERBASIS TRAINING KIT KONTROL MOTOR AC 3 PHASA DENGAN PROTOKOL MODBUS RTU MENGGUNAKAN HMI PADA PEMBELAJARAN DI SMKN 3 BUDURAN SIDOARJO

DEVELOPMENT OF SOLAR POWER PLANT TRAINING KIT TEACHING MODULE ON THE LEARNING ELEMENTS OF ELECTRIC POWER INSTALLATIONS

Penelitian ini bertujuan untuk mengembangkan modul ajar berbasis training kit kontrol motor AC 3 fasa yang terintegrasi dengan protokol Modbus RTU dan Human Machine Interface (HMI) guna mendukung proses pembelajaran di SMKN 3 Buduran Sidoarjo pada Kopetensi Keahlian Teknik Kelistrikan Kapal. Pengembangan modul ini dilatarbelakangi oleh temuan saat PLP, yaitu kurangnya media ajar yang kontekstual dan aplikatif dalam pembelajaran sistem kontrol motor listrik, sehingga peserta didik mengalami kesulitan memahami materi. Metode yang digunakan dalam penelitian ini adalah Research and Development (R&D) dengan model ADDIE (Analysis, Design, Development, Implementation, Evaluation). Validasi dilakukan oleh ahli materi dan ahli media, uji kepraktisan melalui angket respon peserta didik dan uji keefektifan melalui pretest dan posttest. Hasil validasi menunjukkan bahwa modul ajar tergolong sangat valid, dengan persentase skor dari ahli materi sebesar 91%, serta dari ahli media sebesar 92%. Uji kepraktisan menunjukkan bahwa modul dinilai sangat praktis, dengan rata-rata skor persentase sebesar 83% berdasarkan tanggapan peserta didik. Karena valid, praktis, dan efektif maka modul ajar yang dikembangkan layak digunakan dalam pembelajaran lebih interaktif dan aplikatif dalam ranah kognitif dan psikomotorik. Hasil penelitian ini diharapkan dapat menjadi referensi pengembangan perangkat ajar di SMK lainnya, serta memberikan kontribusi nyata dalam meningkatkan mutu pendidikan vokasi.

This research aims to develop a teaching module based on a 3-phase AC motor control training kit that is integrated with the Modbus RTU protocol and Human Machine Interface (HMI) to support the learning process at SMKN 3 Buduran Sidoarjo on Ship Electrical Engineering Expertise Competence. The development of this module was motivated by the findings during PLP, namely the lack of contextual and applicative teaching media in learning electric motor control systems, so that students had difficulty understanding the material. The method used in this study is Research and Development (R&D) with the ADDIE (Analysis, Design, Development, Implementation, Evaluation) model. Validation is carried out by material experts and media experts, practicality tests through student response questionnaires and effectiveness tests through pretests and posttests. The validation results showed that the teaching module was classified as very valid, with a score percentage from material experts of 91%, and from media experts of 92%. The practicality test showed that the module was considered very practical, with an average percentage score of 83% based on student responses. Because it is valid, practical, and effective, the teaching modules developed are suitable for use in more interactive and applicable learning in the cognitive and psychomotor realms. The results of this research are expected to be a reference for the development of teaching tools in other vocational schools, as well as make a real contribution to improving the quality of vocational education.
