Simulation of Chemical Oxygen Demand Using Virtual Reality Technology

Chemical Oxygen Demand (COD) is an important factor in sewage treatment, serving as a significant indicator of the level of organic pollution in wastewater. Proper monitoring and analysis are essential to ensure the efficiency of treatment procedures. Students will be able to enhance their expertise through laboratory and pilot investigations focusing on the measurement of COD levels in sewage. Therefore, we developed a virtual laboratory that utilizes virtual reality technology to conduct the Chemical Oxygen Demand (COD) Determination experiment, which is essential for the Sewage Treatment Technology (TPL) course. This virtual laboratory utilizes the Oculus Quest 2 device. This simulation was developed for students of the Department of Industrial Chemical Engineering, Faculty of Vocational Studies, Institut Teknologi Sepuluh Nopember (ITS) Surabaya. This virtual reality experience was developed using Unity version 2019.4.21f LTS, the C# programming language, and the Unity WebXR Exporter. We then exported the application to WebXR. Although it was necessary to overcome specific challenges, this simulation provided significant benefits for functional and user testing.
