Abstract:
This research aims to 1.) Develop the of three phase induction motor fault analysis
program, 2.) Develop the problem-based training course for the topic of fault of three
phase induction motor, 3.) Find the achievement result of the problem-based training
course for the topic of fault of three phase induction motor, 4.) Find the satisfaction of the
participants in the problem base training course for the topic of fault of 3-phase induction
motor. The research procedure is divided into 2 steps which are the development of
three-phase induction motor fault analysis program and the development on the
problem-based training course. The research tools were questionnaire, test and the
problem-based training set. The experts are divided into 2 groups: the 16 experts who
examine the research tools and the 18 experts who joined the discussion group about
research. The sample groups for this research are 15 technicians whose jobs related to
maintenance three phase induction motor. The results were found that 1) the program for
analyzing fault of three phase induction motor could detect the fault of broken rotor bar and
short-turn stator better than the detect of the bearing fault. The experts comment on the
aspect of the program design was rated in very good level, when the aspect of the program
operation was also rated in very good level, 2) The problem-based training course consists
of manuals for instructor and trainees. The learning activity procedure consists of problem
presentation step, learning objective construction step, data research step, conclusion and
assessment. The experts comment on the aspect of the training pattern and the
appropriateness of the content was rated in good level. The achievement of theory base
knowledge of the participants was 75%, while the achievement for practice base knowledge
was 87.86%. The satisfaction of the participants on the problem base training was rated in
good level.
This research concluded that the analyzing program for fault of 3-phase induction
motor can be substitution analysis for fault of 3-phase induction motor by analyzing
vibration signal and the problem - based training course is the training course focus on the
participants as the learning center which increase the achievement of the participants in
theory and experience.
