Performance Analysis of Pressure and RPM on the Hydraulic Swing Component of a Mini Excavator Trainer

Abstract

A learning method is essential to achieve the existing curriculum standards. For success in the learning process, media or teaching aids are needed to enhance the process and learning outcomes related to students' levels of thinking (Suwardi et al., 2014). The mini excavator trainer serves as one of the solutions to support learning in hydraulic systems. The development of the hydraulic swing component is intended to improve the components of the mini excavator trainer, which will later be developed into a teaching aid for hydraulic drive systems. The ultimate goal of this research is to create a hydraulic swing component to be installed on the mini excavator trainer and, finally, to determine the pressure and RPM performance of the hydraulic swing component. Based on the research conducted, operating the mini excavator trainer requires a radius dimension or distance from the center point to the warning line of 3 m², with a maximum pressure of 150 kgf/cm² producing 11.17 RPM, while the allowable pressure to operate the hydraulic swing component on the mini excavator trainer is 100 kgf/cm², producing 8.54 RPM.
