Abstract

ABSTRACT
Machine Element II learns about transmission systems including power and speed calculations, introduction of power transfer components in the form of gears, belts & pulleys. Given the importance of the material in this
course, it is important to bring trainers to support learning. To find out the effectiveness of the trainer, a study was conducted to measure its effect on learning outcomes. Student test result data are then analyzed using the T-test method. The research instrument in the form of 20 items that were tested for validity had the lowest r count value of 0.404 with rtable = 0.3961. Reliability test showed r count = 0.952 and r table = 0.3961. All items are said to
be valid and reliable because r count> r table. Difficulty level is at low-medium level and power difference is at
good level. T-test results showed a significance of 0.016 smaller than 0.05 so that H0 was rejected and H1 was accepted proving that the presence of the trainer had a significant effect on learning outcomes on belt, pulley and gear material in Machine Element II subjects.
