PENGEMBANGAN CORRECTIVE MAINTENANCE MESIN FRAIS UNIVERSAL BERBASIS APLIKASI APPSHEET DI LABORATORIUM PENDIDIKAN TEKNIK MESIN
This study aims to determine the practicality and feasibility of learning media for corrective maintenance of universal milling machines based on the Appsheet application in a mechanical engineering education laboratory. The type of research used is research and development using the 4D model, namely Define, Design, Development and Disseminate. The product was tested on Lecturers, Heads of Laboratories, and students of Mechanical Engineering Education, Sriwijaya University. The test subjects were 2 experts. One-to-one trials 3 people; small group trials were 9 people and field trials were 21 people. Data collection techniques were with material and media expert assessment sheets, and assessment questionnaires for lecturers, heads of laboratories, and students. The average results of the material expert assessment were 83% which was categorized as Strong Valid. The average results of the media expert assessment were 74% which was categorized as Valid. The results of the one-to-one test obtained an average assessment of a scale of 5, namely 88% which can be categorized as Strong practical. The results of the small group trial obtained an average assessment of a scale of 5, namely 83% very practical. The results of the field test trial obtained an average assessment of a scale of 5, namely 79% practical. It can be concluded that the learning media for corrective maintenance of universal milling machines based on the Appsheet application in the mechanical engineering education laboratory is Valid and Strong Practical Keywords: AppSheet, Corrective Maintenance, Milling Machine, Learning Media, Validity, Practicality, 4D Model
