The COVID-19 pandemic has led to increased use of information technology in all community activities, especially in the field of education. One technology used for learning is the virtual laboratory with online learning media. The use of virtual laboratories in Revolution 4.0 was very effective, especially in the current COVID-19 pandemic. Usually, virtual laboratories do not provide feedback to users, especially on how to develop their skills. This study developed a virtual laboratory with personalized Chinese folklore content using artificial intelligence. The ability and willingness of the user are processed by artificial intelligence to determine the model, media and material that the user wants. When tested, this virtual laboratory’s personalization methods obtained an accuracy value of 89.2% according to the users. Keywords: virtual content, Chinese folklore, expert system

All of the learning in the pandemic era uses online learning including practical in the industry that should do all of the students to apply their knowledge.  The practical industry online is very difficult to assement students that the assessment is given from both company and the university. Companies have many parameters to assessment and each company has different parameters. This study uses 14 parameters that are generally used in assessment for practical students and the university side using 10 parameters. The problem is that every parameter has a different weight than it makes it confusing to give marks with manual assessment. This research uses machine learning to fix this problem based on mobile applications for the user interfaces. The result of testing this application had an average accuracy for assessment students based on parameters of companies and universities that is 83,3%.
