PENGEMBANGAN JOBSHEET PERANCANGAN MODEL RODA GIGI BERBASIS PROJECT-BASED LEARNING MENGGUNAKAN AUTODESK INVENTOR

Abstract

This study aims to develop a valid and practical Project-Based Learning (PjBL)-based jobsheet for the CAD/CAM Basics course in the Mechanical Engineering Education program at Sriwijaya University. The research employs the Holistic 4D development model (Define, Design, Develop, Deploy) and was conducted during the even semester of the 2024/2025 academic year. The subjects of this study were students from the Mechanical Engineering Education program at Sriwijaya University. Data collection instruments included validation and practicality questionnaires. The validation results from material experts and media experts showed scores of 91.6% (highly valid) and 87.2% (highly valid), respectively. Practicality testing involving 28 students yielded a score of 92% (highly practical). The jobsheet, designed using Canva and Autodesk Inventor, includes step-by-step instructions, technical drawings, and assessment rubrics. The findings indicate that the PjBL-based jobsheet is valid, practical, and enhances students' skills in designing a jobsheet through independent learning.

Penelitian ini bertujuan mengembangkan jobsheet mata kuliah CAD/CAM Dasar berbasis Project-Based Learning (PjBL) yang valid dan praktis di Program Studi Pendidikan Teknik Mesin Universitas Sriwijaya. Metode penelitian menggunakan model pengembangan The Holistic 4D (Define, Design, Develop, Deploy). Penelitian dilaksanakan pada semester Genap Tahun Akademik 2024/2025. Subjek penelitian dari ini adalah mahasiswa Pendidikan Teknik Mesin Universitas Sriwijaya. Instrumen dalam penelitian menggunakan angket validasi dan angket kepraktisan. Hasil kevalidan oleh  validator materi dan validator media, dengan hasil validasi ahli materi menunjukkan skor 91,6% (sangat valid), dan ahli media 87,2% (sangat valid). Serta hasi uji kepraktisan pada 28 mahasiswa memperoleh skor 92% (sangat praktis). Jobsheet ini dirancang dengan platform Canva dan Autodesk Inventor, mencakup petunjuk langkah kerja, gambar kerja, dan rubrik penilaian. Hasil penelitian menunjukkan bahwa jobsheet berbasis PjBL valid dan praktis serta meningkatkan keterampilan mahasiswa dalam mendesain sebuah jobsheet dengan pembelajaran mandiri.
