Institutional Repository UIN Sunan Kalijaga YogyakartaREVERSE ENGGINEERING: PERANCANGAN ULANG BASEFRAME DAN ARM BRACKET PANTOGRAF KERETA REL LISTRIKNIM.: 22106060048Abdurrasyid MusyaffaauthorThis study aims to re-engineer the baseframe and arm bracket components on the Electric Rail Train (KRL) pantograph at PT. Industri Kereta Api (INKA). The main problem studied is the need to localize production which is still hampered by product conformity with ToyoDenki licensing standards. The methodology used integrates the Non-Functional Requirement Analysis (NFRA) method for identifying mechanical characteristics, the Analytical Hierarchy Process (AHP) for determining criteria priorities based on stakeholder assessments, and Quality Function Deployment (QFD) through the preparation of the House of Quality (HoQ) as a framework for component testing. The resulting component specifications are deformation resistance, corrosion resistance, weld joint strength, stress resistance, strain resistance, low temperature resistance and high temperature resistance. The resulting technical requirements are material selection, weld beld size, application of corrosion paint and dimensional conformity. The results show that deformation resistance and weld joint strength are the main priority specifications and material selection and component dimensional conformity are the main technical requirements. The component redesign resulted in a 3D design using SolidWorks software for three main components, namely the baseframe, lower arm bracket, and upper arm bracket, which were then tested with static loading, temperature resistance tests, and vibration tests according to the test frame. Based on the simulation, three alternative structural steel materials were identified, namely S235JR, S275JR, and S355JR, where S355JR showed the best safety factor value for resisting pressure. In conclusion, the integration of the QFD and AHP methods used for the creation of the test frame directed the component testing process based on customer needs.670 Teknik Industri2026-05-25UIN SUNAN KALIJAGA YOGYAKARTA;FAKULTAS SAINS DAN TEKNOLOGIThesis
