3D-virtual lab to resolve laboratory work’s problem during COVID-19 pandemic

Laboratory work is tremendously notable in chemistry learning process in order to construct the theory that has been obtained in the regular class. However during the Covid-19 pandemic laboratory work has never been conducted since the pandemic started out as an outbreak in Wuhan because the government banned any offline learning process at school. Therefore in this case this study set out to develop a 3D-virtual lab to overcome this obstacle. The 3D-virtual lab is urgently required since it could be employed as a supplement or a substitute as long as the laboratory work in a conventional lab is still restricted. In this study, the research and development cycle model consists of five stages namely the ADDIE (Analysis, Design, Development, Implementation, and Evaluation). The material developed was acid-base titration. The product was run properly with the help of oculus and controller devices. The product was validated by three experts based on the content, the learning instruction, and the technique aspects. The validation results were in the form of score and suggestions. The validation score of the product given by the experts was 0,83 and then the data suggestion was applied to develop the product itself. The next step was product legibility assessment that was conducted by eight educators and twenty four students. The three aspects (content, learning, and technique) were assessed by educators while only one aspect (technique) was assessed by students. Evidently it was found that the product legibility score given by educators was 94%. Whereas the legibility of the product given by students was 98%. The data analysis was proven valid in terms of the criteria and feasible to use after conducting evaluation. Therefore, evidently the 3D-virtual lab becomes one of learning media that enables the students to conduct online laboratory work during the pandemic. In addition, the 3D-virtual lab minimizes any risks during the conventional laboratory work or guarantees safety, reduces the operational cost, and makes laboratory work more accessible.
