The Effect of Using a CNC Simulator in Learning the Mechanical Engineering Skills Program

Abstract

The 21st century is better known as the digital era, an era of rapid development of information technology with data-based document management, digital transformation, and network-based communications. The research aims to evaluate the use of computer numerical control (CNC) simulators, analyze the effect of using CNC simulators, and find factors inhibiting the use of CNC simulators in learning Mechanical Engineering at Muhammadiyah 1 Playen Gunungkidul Vocational High School (SMK). The research uses quantitative methods by conducting experiments. The experimental design used is quasi-experimental or quasi-experimental design research. The variables used in this research are the independent and dependent variables. The research was carried out at Muhammadiyah I Playen Vocational School. The research subjects were students of class XII Machining Engineering, which consisted of three classes. The data obtained was analyzed using the SPSS 20.0 for Windows application for normality testing and hypothesis testing. The research results show that using CNC simulators in learning the Mechanical Engineering Skills Program at SMK Muhammadiyah 1 Playen Gunungkidul went smoothly. The results of the t-test analysis for the experimental class and control class obtained sig. (2-tailed) experimental class is 0.000< 0.05, and sig. (2-tailed) control class is 0.001. 0.001<0 .05. There is an inhibiting factor in using CNC simulators in learning the Mechanical Engineering Skills Program at SMK Muhammadiyah 1 Playen Gunungkidul; namely, the number of CNC simulators provided is still limited, with the lowest type of CNC simulator.
