Design and Need Analysis of Computer Devices’ Expert System Using Forward Chaining Method

This study aimed to: 1) Analyzing description of Core Competency and Basic Competency on Assembly of Computer Devices subject, establishing the concept of the subject and analyzing the students; 2) to know what was the obstacles that were faced by teacher during teach Assembly of Computer Devices subject 3) to know what was the instructional media that needed to be designed on Assembly of Computer Devices subject; 4) designing instructional media that was designed on Assembly of Computer Devices subject. The method in this study used SDLC (System Development Life Cycle), Waterfall. From the results of this study, it can be concluded, were follows: Assembly of Computer Devices subject was one subject that is difficult to teach through lecturing because it was practicing. So, the teacher needed instructional media that could help students so that could use it on practicing of Assembly of Computer Devices subject. That is designing instructional media based on an expert system, it could help the student to identify computer damage on Assembly of Computer Devices subject. Design of instructional media based on the expert system used UML (Unified Modelling Language) process.
