RANCANG BANGUN DAN UJI KINERJA ALAT TAMBAL BAN PORTABEL SEPEDA MOTOR MENGGUNAKAN PEMANAS KAWAT NIKELIN

Abstract

This study aims to design and evaluate the performance of a portable motorcycle tire repair tool based on a nickel-chromium (Ni–Cr) heating element as an efficient solution for on-site tire patching. The device was developed using an engineering experimental approach, which included stages of design, prototype fabrication, and performance testing of both thermal and mechanical aspects. The results showed that the heating system achieved an optimal working temperature range between 86°C and 168°C, with an average heating time of 5.2 minutes under a 12V DC power supply—meeting the requirements of rubber vulcanization during tire patching. In terms of efficiency, the system demonstrated thermal efficiency of 80–85% with relatively low power consumption. Mechanical analysis of the frame and locking bolts indicated adequate structural strength with a safety factor greater than three. Overall, the tool exhibited advantages in time efficiency, portability, and ease of operation compared to conventional repair methods. These findings are significant as a foundation for further development of next-generation portable tire repair devices featuring automatic temperature control and more flexible power sources.
