Abstract

Utilizing solar thermal energy as an energy source to supply electric car batteries in Indonesia is a big solution for reducing carbon gas emissions and the use of fossil fuels. This research aims to provide an alternative energy source for electric vehicle batteries and apply design concepts to electric vehicles in Indonesia. The method applied is a qualitative approach with literature analysis and literature study. The research results show that in a comparative analysis of the use of solar thermal energy in electric cars with conventional vehicles that use fossil fuels, there is a significant difference in reducing carbon emissions. The results of the analysis also strengthen the argument about the superiority of electric cars in terms of environmental friendliness so that the design concept for implementing solar thermal energy in electric vehicles in Indonesia becomes very effective to implement.

Abstract

Motor vehicle emissions and energy efficiency are key concerns in developing environmentally friendly automotive technologies, particularly for small-capacity motorcycles, which remain the dominant mode of transportation in Indonesia. This study aims to analyze the effect of using the AHLM (Adaptive High-Performance, Low-Pollution Muffler) on fuel consumption and engine performance in a Honda 110 cc motorcycle. The research employed a comparative experimental method using three types of exhaust systems: standard, free flow, and AHLM. Tests were conducted using an engine dynamometer to measure torque and power, and a fuel consumption tester to record the time required to consume 10 ml (0.0074 kg) of fuel, calculated using the conversion formula m = (V_ml / 1000) × ρ, at three engine speeds: 1500 rpm, 2500 rpm, and 3500 rpm. The results show that the free flow exhaust produced the highest torque and power, at 10.9 Nm and 11.7 HP at 9000 rpm, respectively, but with higher fuel consumption. Conversely, the AHLM exhaust demonstrated better fuel efficiency, with consumption rates of 0.083 kg/h at 1500 rpm, 0.317 kg/h at 2500 rpm, and 0.416 kg/h at 3500 rpm, closely matching the efficiency of the standard exhaust. Although its peak power was slightly lower, the AHLM maintained stable torque and efficient combustion across all engine speeds. In conclusion, the AHLM exhaust system provides an optimal balance between performance and energy efficiency, offering potential as an adaptive exhaust technology that is both effective and environmentally friendly for small-capacity motorcycles.
