Abstract
This study aims to develop a virtual laboratory application based on virtual reality simulation as a training tool for turning machines. The application is built as a solution for manufacturing engineering education problems at the Production System Laboratory (PSL) in the Industrial Engineering Department, Diponegoro University. Problem based on work accident data shows human error from the student when using turning machines. The data shows that lack of student understanding due to insufficient of preliminary training at the beginning of manufacturing engineering education especially physical skills training. Virtual Reality Simulation is chosen because conventional machining training has some restrictions in execution. Furthermore, virtual reality simulation can reduce cost, improve safety, and add flexibility along with advances in computer technology. For this Research the Goal-Directed Design (GDD) method was chosen to develop VR simulation. This method is used as a procedure to accomplish the good design of application which including research, modelling, requirements, framework, refinement, and support. The application is built using Unity 3D software and run on Oculus Quest hardware. At the evaluation phase for assessing the needs, researchers use functional and non-functional requirements. Functional requirements consist of interaction, visualization, and information. Non-functional requirements consist of usability, performance, and reliability.
