Abstract

Forward chaining is one of the chaining methods other than backward chaining in the expert system. It starts from an event or fact to produce a solution. Prior to commencing, knowledge of a case must be represented. The case in this research is the problem of skin diseases caused by fungal infections experienced by humans. Knowledge about the type of skin diseases due to fungal infection was obtained from various sources of literature and experts. Then, the knowledge was represented using rules in the form of IF-premise THEN-conclusion. Forward chaining was performed on facts that match the state of the symptoms of skin diseases to make the most likely diagnosis of skin diseases and how to treat it. This system was developed based on computer program. System testing was done by consultation techniques between users and the system. The system asked questions as the premises that must be answered bythe user. If the user's answer was in accordance with the rules that had been compiled as a form of knowledge representation, then the solution would be achieved as a conclusion. This solution was the most likely diagnosis of fungal skin disease.
