HYDRAULIC TRAINING SET POWERED BY ELECTRICITY AND PROGRAMMABLE LOGIC CONTROLLER

Abstract

This research obtains quality hydraulics training set powered by electricity and Programmable Logic Controller (PLC) for teaching student. By selecting, a specific sample group is an undergraduate student in mechanical engineering a total of 22 people who were the sample group. The research process consisted of the establishment and assessment of hydraulic training set. Statistical data were analyzed using mean and standard deviation and percent. The tools utilized in this research were hydraulic training set and worksheet for designing and connecting hydraulic circuits.The results found that the characteristics of   a training set had two cylinders, which were controlled with electrical and PLC. All accessories were assembled and installed on the wheel base.The training set was in suitable size, portable, reliable, and covered the skills of subject area in the courses, through the 12 trial worksheets. The quality assessment of training set by experts was  good ( = 4.21, SD = 0.18), the quality of usage was very good ( = 4.54, SD = 0.18), the quality of worksheets was good ( = 4.30, SD = 0.24), and the overall quality of the training set was  good ( =4.35, SD = 0.17). The efficiency of the training set and the worksheet when applied to the student group were 82.40/83.24, which was based on the criteria of 80/80 in research hypothesis.
