PENGEMBANGAN JOBSHEET BERBASIS CASE METHOD CNC LATHE 2A DI PROGRAM STUDI PENDIDIKAN TEKNIK MESIN FKIP UNSRI

Abstract

This study aims to develop a case method-based jobsheet for the CNC Lathe 2A subject in the Mechanical Engineering Education Study Program, FKIP, Sriwijaya University. The research employs a Research and Development (R&D) method using the 4D model (Define, Design, Develop, Disseminate). The product is a printed jobsheet that includes essential elements such as course learning outcomes, sub-outcomes, parameters, safety aspects, work steps, and evaluation sheets. Feasibility tests involved validation by content and media experts, while practicality tests included one-to-one, small group, and field test stages. Validation results showed that the developed jobsheet is highly feasible for use in CNC Lathe instruction. Practicality testing indicated that students found the jobsheet easy to use, engaging, and helpful in improving contextual and applicable understanding of the material. The case method was considered effective in fostering critical thinking, analysis, and problem-solving skills. It is recommended that this jobsheet be adopted as instructional material for the CNC Dasar course and further developed into digital or interactive formats.

Penelitian ini bertujuan untuk mengembangkan jobsheet berbasis case method pada materi CNC Lathe 2A di Program Studi Pendidikan Teknik Mesin FKIP Universitas Sriwijaya. Penelitian ini menggunakan metode penelitian dan pengembangan (R&D) dengan model 4D (Define, Design, Develop, Disseminate). Produk dikembangkan dalam bentuk jobsheet cetak yang memuat elemen penting seperti CPMK, Sub-CPMK, parameter, aspek K3, langkah kerja, dan lembar evaluasi. Uji kelayakan dilakukan melalui validasi ahli materi dan ahli media, serta uji kepraktisan dilakukan melalui tahapan one-to-one, small group, dan field test. Hasil validasi menunjukkan bahwa jobsheet yang dikembangkan sangat layak digunakan dalam pembelajaran CNC Lathe. Dari uji kepraktisan, respon mahasiswa menunjukkan bahwa jobsheet mudah digunakan, menarik, dan membantu meningkatkan pemahaman materi secara kontekstual, aplikatif, dan ringkas. Penggunaan case method dinilai efektif dalam melatih kemampuan berpikir kritis, analisis, dan pemecahan masalah. Disarankan agar jobsheet ini digunakan sebagai bahan ajar dalam mata kuliah CNC Dasar serta dapat dikembangkan lebih lanjut dalam bentuk digital atau interaktif.
