Abstract

The inappropriate use of heavy equipment in the field's conditions and situations can result in various losses, including low production, failure to meet scheduled targets, or unnecessary repair costs. Troubleshooting in the lubrication system often occurs due to reduced flow in the distributor and clogged distributor lines. The aim of this research study is to understand the troubleshooting process performed on the automatic lubrication system of the Bucket Wheel Excavator-205 substructure. Although automatic lubrication systems are designed to enhance efficiency and operational reliability, technical issues can sometimes occur, disrupting system performance. Data collection methods include field observations, data analysis, and experiments. The research findings indicate that common problems include lubricant leaks, decreased lubrication pressure, and sensor malfunctions. Based on the analysis of causes, appropriate solutions have been implemented, including mechanical repairs, replacement of damaged components, and enhanced preventive maintenance. It is hoped that the results of this research will contribute to improving the efficiency, reliability, and lifespan of the automatic lubrication system on Bucket Wheel Excavator-205, as well as providing guidance for better maintenance in the future.

Abstract

Composite is a material that is formed from a combination of 2 or more materials. The orientation of the inclination angle of the webbing on the composite affects the tensile strength value. This research was conducted to determine the effect of variations in the angle of inclination of the webbing and the phenomenon of delamination on the value of tensile strength. The process of making fiberglass woven fiber composites and a mixture of resin and catalyst uses the vacuum bagging method. The variations used in this study are the angle of inclination of the webbing 0°, 15°, 30° and 45°. Tensile test specimens using the ASTM D638 standard. The specimens that have been cut will then be perforated with a diameter of 4 mm using a milling machine. Tensile testing was carried out using a Universal Testing Machine. The highest tensile strength value is at an angle of 0° with a value of 189.30 MPa and the lowest tensile strength is at an angle of 45° with a value of 34.25 MPa and for the value of the delamination factor has little effect on the value of tensile strength.
