This study aims to examine the use of compact crucible furnace for the metal casting practice as a part of the Mechanical Technology subject at vocational high school SMK Muhammadiyah 1 Playen. The research method used was quasi experiment with nonequivalent control group design. The research population was all of the Grade 10 students in the Machining Engineering study program at SMK Muhammadiyah 1 Playen, with a total of 115 students. Class X MB, which consisted of 33 students, was picked as the experiment group, while Class X MC, with 36 students, was picked as the control group. Once the data were collected through observation and tests, the test scores were then analyzed with a difference test. The findings suggest that the scores of both the experiment and control groups increase with a gap of 51% and 25.89%, respectively. The mean score of the experiment group is 78.08, while that of the treatment group is 68.18. In conclusion, the experiment group has a higher score increase gap with 25.11% compared to the control group. © Published under licence by IOP Publishing Ltd.
