Goat farming business will experience problems when the goat is infected with the disease. Therefore, goat health was the most important factor because it can affect the quality of the meat, milk or skin produced.

The result of the consultation was the diagnosis of the disease and how to treat it. The expert system research uses the Dempster Shafer method. The testing of the research that has been carried out has a system accuracy rate of 97.5%
