After experiencing a delay in knowing the illness, of course in the treatment will also experience a delay because it is already worse the disease. People who suffer from lung health problems tend to ignore the symptoms or pain they feel until finally the disease gets worse. After the disease gets worse then the patient conducts an examination at the hospital. This study aims to help users to know the diagnosis of lung disease early on the basis of symptoms that are felt so that appropriate treatment can be done in accordance with the characteristics of the disease in the user. In the application of this expert system, it is assisted by the Dempster Shafer method. Dempster Shafer is a mathematical theory for proof based on belief functions and plausible reasoning, which is used to combine separate pieces of information (evidence) to calculate the likelihood of an event. On this basis, a system that can help the user to be able to diagnose lung disease will be made according to the symptoms found in the user who has the disease.} }
