PENGEMBANGAN E-MODUL CNC TURNING TIPE KRISBOW CKE6130i UNTUK MENINGKATKAN KOMPETENSI CNC MAHASISWA S1 PENDIDIKAN TEKNIK MESIN UNIVERSITAS NEGERI SURABAYA

DEVELOPMENT OF A CNC TURNING E‑MODULE OF THE KRISBOW CKE6130i TYPE TO IMPROVE CNC COMPETENCE OF UNDERGRADUATE MECHANICAL ENGINEERING EDUCATION STUDENTS AT UNIVERSITAS NEGERI SURABAYA

Penelitian ini bertujuan mengembangkan e‑modul CNC Turning tipe Krisbow CKE6130i serta mendeskripsikan kelayakan, respon mahasiswa, dan hasil belajar setelah penggunaan e‑modul pada mata kuliah CNC di Program Studi S1 Pendidikan Teknik Mesin Universitas Negeri Surabaya. Penelitian pengembangan menggunakan model 4D (define, design, develop, disseminate) dengan uji coba terbatas pada 10 mahasiswa. Hasil validasi ahli materi dan media menunjukkan rata‑rata skor kevalidan 3,46 dengan persentase kelayakan 86,46% (kategori sangat valid dan sangat layak). Instrumen tes kognitif dan lembar kinerja psikomotorik memiliki rata‑rata skor kevalidan 3,48 dengan persentase kelayakan 86,90% sehingga dinyatakan sangat layak sebagai alat ukur. Respon mahasiswa terhadap e‑modul berada pada kategori sangat baik dengan persentase rata‑rata 86,43%. Hasil belajar meningkat dari rata‑rata 56 (pre‑test) menjadi 85,1 (post‑test) dengan ketuntasan 100%, nilai N‑Gain 0,661 dalam kategori sedang, dan rata‑rata kinerja psikomotorik 80,2 dalam kategori baik, sehingga e‑modul dinyatakan efektif mendukung peningkatan kompetensi CNC mahasiswa.

This study aims to develop a CNC Turning e‑module of the Krisbow CKE6130i type and to describe its feasibility, students responses, and learning outcomes after its use in the CNC course of the Bachelor Program in Mechanical Engineering Education at Universitas Negeri Surabaya. The research employed a 4D development model (define, design, develop, disseminate) with a limited trial involving 10 students. Validation by material and media experts yielded an average validity score of 3.46 with a feasibility percentage of 86.46%, indicating that the e‑module is very valid and very feasible. The cognitive test and psychomotor performance rubric obtained an average validity score of 3.48 with a feasibility percentage of 86.90%, so they are considered highly feasible as assessment tools. Students responses to the e‑module were in the very good category, with an average percentage of 86.43%. Learning outcomes increased from an average score of 56 (pre‑test) to 85.1 (post‑test) with 100% mastery, an N‑Gain value of 0.661 (medium category), and an average psychomotor performance score of 80.2 (good category), indicating that the developed e‑module is effective in enhancing students CNC competencies.

Keywords: e‑module, CNC turning, Krisbow CKE6130i, CNC competence, student response.
