The rapid development of technology can cause problems for technology users themselves. One of the problems with technology like MiChat is that it is used as a means of communication to commit crimes. These problems include rampant prostitution, fraud, gambling, and selling illegal drugs. In addition, law enforcement officials can take smartphones used in crimes as evidence. Therefore, valid evidence needs to be investigated using an approach to digital processing evidence called digital forensics. Integrated Digital Forensic Investigation Framework Version 2 (IDFIF v2) is one of the methods applied to investigate smartphones. The IDFIF v2 framework is the latest framework developed specifically for use in smartphone research. This research has several general stages: preparation, incident response, laboratory process, and presentation. The final result of this study is to report the results of database searches on smartphones and analyze smartphone evidence.
