Identification of the Causes of Dirty Fuel Filters in Auto Workshops for Optimizing Vehiche Maintenance

Abstract

Fuel is one of the tools to drive the machining system that moves from the fuel tank to the engine. Although there are several areas that have switched to using electric vehicles, vehicles that use fuel oil still dominate the public in various countries. The purpose of this research is to identify the causes of a dirty fuel filter in an auto repair shop. The methods used in this analysis are Failure Mode and Effect Analysis (FMEA) and fishbone diagram analysis. Based on the results and discussion, the cause of the dirty fuel filter is the causal factor from the method side, namely due to negligence in maintenance, from the material side because the fuel tank is dirty and the fuel is not good, from the engine side because of continuous use without maintenance, from the human side because it is not routine maintenance, due to carelessness in maintenance, and due to frequent changes in the type of fuel.
