This research aims to determine the level of vibration of the lathe and the influence between machine vibrations with the results of the practice products of students of machining techniques of PIRI 1 Vocational High School in Yogyakarta. This research is a quantitative research with an experimental approach. The subject of this research was class XII students and the object of this study was the lathe in the machining workshop of PIRI 1 Vocational High School. Data collection techniques using direct observation. Data analysis techniques using descriptive analysis and regression analysis. Based on research results it is known that, lathe number 2 is included in the level of unacceptable (dangerous). Meanwhile, lathes number 3 and 6 are in the satisfactory level. And, lathe number 7 is included in the level of good. Furthermore, there is no influence between the vibration of the lathe with the results of the practice products of the students majoring in machining engineering at PIRI 1 Vocational High School. The contribution of the influence of variable lathe vibration by 9%. And the regression equation is Y=57,207+(-11,030) X. © 2024 Author(s).
