Implementing PBL as a teaching method has its advantages and disadvantages. Until now, this method is still used mainly for small classes and students who opted for specialized courses under international law. Also, due to the exceptional circumstances of the outbreak of COVID-19, there has been a modification of the delivery of the PBL using different teaching tools as noted above. The development of learning methods and learning facilities continues to be carried out from time to time with adjustments to existing conditions in society, including the development of information technology.
