Development of 3D Mulitmedia as a Learning Tools Online Based Virtual Reality

Practicum or experiment is an important learning method to be implemented in learning because it can provide direct experience for students to introduce, familiarize, and train students to carry out scientific steps and procedural knowledge. During the COVID-19 pandemic, teaching and learning activities on campus were carried out online including practical courses, it was very difficult to conduct lectures, especially in practicum courses, especially for new students who were still relatively minimal about how to practice in the Telecommunications Laboratory of the Sriwijaya State Polytechnic because of information very limited available. With the advancement of technology today is growing very rapidly. Therefore, multimedia development is carried out. Submission of information about signal processing practicum is to create 3-dimensional virtualization using the Blender application and the Verge3D application to convert 3D modeling so that it can be viewed on a virtual reality-based web browser. virtual reality is a technology that combines a real object with a virtual object that has a real 3D (3D) shape in real-time. This research, we will apply 4 scenarios in building a device for signal processing practicum with VR tehcnology. Scenario 1; Measurement of power supply and high pass filter. Scenario 2; Measuremnet of power supply and band pass filter. Scenario 3; Measurement of power supply and low pass filter. Scenario 4; Measurement of powwer supply and OP-AMP Inverting.
