Abstract

Lack of understanding of students graduating from the Samarinda State Polytechnic Heavy Equipment Engineering Study Program and the availability of facilities in the form of teaching aids that support learning about Electrical Systems, especially Charging Systems at the Samarinda State Polytechnic Heavy Equipment Engineering Workshop. Charging System is a system that converts mechanical energy from the engine into electrical energy to charge the battery and supply electric current to operate the electrical system of a vehicle. When the ignition switch is in the on position and the electric motor is turned on to rotate the alternator, the alternator will carry out its duties in the Charging System and recharge the battery. This teaching aid can explain how the series of components of the Charging System and the working system of the Charging System. The aim of this research is to determine the amount of output supplied by the alternator when it is at a certain RPM with the alternator component belonging to the Caterpillar 390D unit. This teaching aid uses a 24V 95 ampere alternator, 2 HP1 phase AC electric motor, 12V battery, belt and monitor panel as the main components. To support this Charging System props, a stand is used.

Abstract

The hydraulic oil filter is one of the components contained in the hydraulic system which functions to filter the impurities contained in the oil so that it does not circulate into the system. The purpose of this study was to determine the performance of the original and non-original filters in relation to the damage that occurred to the control valve. The results indicated that the damage to the spool valve was caused by hydraulic oil contaminated with water, resulting in corrosion on its surface. Visual inspection of the hydraulic oil filter reveals particles found in the filer element.
