Maintaining physical health must also maintain mental health. In other words, there is no physical health without spiritual health. Based on information from the 2018 Basic Health Research (Riskesdas), there are around 14 million people aged 15 years and over who are depressed. Of these, only 9 percent are undergoing medical treatment. The research also shows that 7 out of 1,000 households in Indonesia have members who experience psychosis or schizophrenia. Ironically, there are not as many psychiatric specialists as in other medical fields. In this case, it is proven by the rarity of hospitals dealing with mental disorders in each region. In order to educate the public about basic knowledge about psychiatric problems, and to minimize inappropriate handling, a tool must be made that can diagnose mental disorders and can make the same choices, as accurately as a psychologist. The target of this research is to create a system that can be used to diagnose mental disorders. The system will be made using the Certainty factor method. The results of this study are a mobile-based application by applying Certainty Factor which can run well, the system can diagnose according to the symptoms experienced and carry out tests that produce a percentage value in Case 1 experiencing gadget addiction 95.251% .} }
