The increasing number of tuberculosis patients in Indonesia is caused by the large number of poor people who lead unhealthy lifestyles and the lack of information provided to the public about tuberculosis.To overcome the existing problems and to increase the knowledge of ordinary people about Tuberculosis, an expert system is made whose knowledge base taken directly from the expertise of certain people transferred in a computer.This TB diagnosis expert system has been successfully built by applying the dempster-shafer method and can provide disease information as well as prevention and treatment.After manual calculations on the Dempster-Shafer method, a confidence level of 0.57 or 50% of the calculation results in the case of Lung TB disease was obtained.
