Abstract

This research uses board paper as the main material for the sandwich panel structure, which is filled with polymeric foam in the sandwich panel, which will then be subjected to mechanical testing, namely bending and compression, to determine the strength of the sandwich panel structure. The test results according to the ASTM C393 M-16 standard show that the bending strength for the honeycomb shape is 11.93 kN, while for the banana tree trunk core shape the bending strength value is 12.34 (kN). Based on the results of the compression test according to the ASTM C365 M-16 standard. The compressive stress strength value obtained was 6,009 N/mm2 for the honeycomb core shape and for the banana tree trunks core shape, the compressive stress strength value was 7,356 N/mm2. It is necessary to use strengthening methods that are stronger and resistant to delamination and shifting on the strength and durability of the material.

Abstract

The process of painting a car cabin at PT XYZ, a leading automotive company in Indonesia, involves a series of structured and rigorous steps to ensure optimal paint quality before the vehicle leaves the manufacturing facility. The painting process involves a series of structured stages, starting from surface preparation to application of paint layers. Paint thickness measurements are carried out to ensure that the thickness of the paint layer complies with established standards for optimal protection and aesthetics. It was found that the company implemented advanced technologies such as electrodeposition (ED) to ensure an even and long-lasting paint layer. Apart from that, implementing grounding safety and the Quality Gate process is key in maintaining safety, quality and customer satisfaction
