Abstract

Fuel-injected motorcycles require accurate fault diagnosis; however, the process often depends heavily on the expertise of mechanics. This study aims to develop a web-based expert system to assist in diagnosing engine failures in fuel-injected motorcycles using the Dempster-Shafer method, which is designed to logically handle uncertainty in information. The system was developed using the Waterfall model and tested through black-box testing and accuracy evaluation based on 16 cases submitted by 10 mechanics. The test results indicate that the system functions as intended and achieves a diagnostic accuracy rate of 93.75% compared to expert diagnoses. These findings suggest that the expert system can serve as a valid support tool for diagnosing engine failures based on identified symptom data.
