Pengaruh Variasi Tekanan Ban terhadap Konsumsi Energi dan Efisiensi Energi pada Kendaraan Prototype Listrik Universitas Mataram

Abstract

The development of electric vehicles in Indonesia has shown significant progress, in line with the target of zero greenhouse gas emissions by 2060. Electric vehicles require efficient energy management, where tire pressure is one of the important factors that affect energy consumption, efficiency, and vehicle performance. This study aims to analyze the effect of tire pressure variations on energy consumption, energy efficiency, and average speed on the University of Mataram prototype electric vehicle. The research method used is a quantitative approach with direct testing on vehicles using tire pressure variations (25 PSI, 30 PSI, and 35 PSI) and a gear ratio of 10.29. The results showed that 35 PSI tire pressure resulted in the lowest energy consumption (8.333 Wh/km) and the highest energy efficiency, while 25 PSI tire pressure resulted in the highest energy consumption (10 Wh/km) due to greater rolling resistance. The average vehicle speed also increased as tire pressure increased, from 21.83 km/h at 25 PSI to 23 km/h at 35 PSI. This study confirms that optimal tire pressure settings can improve energy efficiency, reduce rolling resistance, and support overall electric vehicle performance.
