Abstract

The CC 205 locomotive at the UPT Locomotive Depot Divre IV Tanjung Karang is a train that uses diesel fuel. The locomotive at UPT Locomotive Depot Divre IV Tanjung Karang experienced compressor damage, which required component replacement. This research aims to identify and carry out the process of treating valve leaks in locomotive compressors. Observation, interview, and documentation are used to obtain appropriate data and results. Maintenance carried out on this locomotive is necessary so that the CC 205 locomotive can be used optimally without any doubt. Maintenance is an activity in maintaining existing facilities by carrying out repairs or replacements necessary to maintain the condition of these components so that they are always in maximum condition. The analysis results show that air leaks in the compressor caused by compressor valve leaks can cause the pressure in the main tank not to be filled.

Abstract

Temperature is one of the parameters that is very influential in the process of making HDPE matrix composites. This study aims to determine the effect of variations in heating temperature on tensile strength and bending strength and to analyze the fracture structure of HDPE composites. The materials used in this study were HDPE plastic from used bottles, coconut fiber and Sansevieria fiber with a composite ratio of 90:5:5. The process of making HDPE composites is carried out using the hot press compression method. The pressure used is 30 bar for 30 minutes. The temperature variations used are 150ºC, 160ºC, 170ºC, 180ºC, and 190ºC. This study conducted two tests, namely tensile testing and bending testing using the Universal Testing Machine. The tensile testing process uses the ASTM D 3039 standard and obtains the highest results on specimens of 170ºC with a tensile strength value of 509.80 MPa. The value of tensile strength has increased and decreased. The bending test process was carried out according to the ASTM D 790 standard and the highest results were obtained on the 170ºC specimen with a value of 90.99 MPa.
