P PT. Krama Yudha Ratu Motor is one of companies which creating a diversified commercial vehicle products. Based on data from defective products CJ-M in January-March in 2011, it is known that the largest percentage of defects found in the process of Painting, it is known that there is a failure during the process of Painting that resulted percentage of disability, to overcome the failure, it is using an application method: Failure Mode and Effect Analysis (FMEA). The methods are used to analyze the risk of failure from any process that occurs in Painting process. Initial stages of determining the effects on the product, then, failure modes and causes, control and reduction efforts undertaken should be done to tackle the type of failure, then the calculation of RPN values of multiplication the severity, occurrence and detection. After a stage of FMEA which is the initial capital of designing expert systems will be designed an expert system to assist in tracking and identifying completion the risk of process failure. In the selection process of identifying problems and the selection of experts, these chosen experts are chief Trouble Shooting Painting and Senior Engineering. Further acquisition of knowledge, then the representation that begins with the effects that occur on the finished product, then the type of failure and the cause, then obtained a conclusion that contains the main cause and the prevention efforts based on the level of value Occurance. Later stages of the nference mechanism used is forward chaining and tracking techniques used is Depth-first search.
