information, to attempt repairs if there is damage to the motorcycle. therefore, needed a
solution for users in studying the damage to the motor and the existence of a motor damage
and determine what types damage to the motor with the help of expert system uses
advanced trace inference method (forward Chaining). This application is a web-based
display using the programming language PHP CodeIgniter Framework by using Sublime
Text 3 Editor and MySQL as the database. Damage to parts of the engine occurred due to
negligence in performing maintenance. Car owners need a periodic maintenance by
detecting any damage that occurs on the motor. Motorcycle owners should receive
