Z80 Simulator for improving Student Competence in Microprocessor Field of Subject

This paper presents the use of “Z80 Simulator” for enhancing the student competence in the practice course of microprocessor subject at Electrical Engineering Department, Yogyakarta State University. According to the Classroom Action Research method, there are four stages that should be taken, firstly is planning for action, second step is implementation of the action by using Z80 Simulator in the classroom, the following step is observation of the learning process and the final stage is reflection based on the observation data. Performance measured in this paper is the suitability of Learning Process with a plan of action and the percentage of students who get B score and above. The result shows that a) the Learning Process in the microprocessor field of subject by using Z80 Simulator not optimal yet in certain terms, b) the Learning Process by using the Z80 microprocessor simulator can obtain the number of students who got a B score reaches 75%
