Air pollution has been identified as a global problem that negatively impacts. One of the largest contributors is motor vehicles, especially in the production of hydrocarbon (HC) and carbon monoxide (CO). This research developed a catalytic converter based on activated carbon that was synthesized from rice husk biomass. The successfull of activated carbon synthesis was evaluated by scanning electron microscopy - energy dispersive x-ray (SEM-EDX) that confirmed the carbon element contained was 51,99 wt% with an average pore size of 10 μm. The activated carbon was then formed into four catalytic converter designs consisting of doughnut, honeycomb, pellet, and gear. Emission tests showed the doughnut design was most effective in reducing HC and CO emissions by 82.22% and 53.87%. The best catalytic converter were then subjected to further testing to confirm that the addition of activated carbon-based catalytic converter does not reduce the performance. The results showed the decrease of power and torque, respectively in 3.10% and 7.37%, The noise test confirmed that it had no significant effect, the decrease in noise value that occurred was only about 3.75%. This means the catalytic converter is not a reducer and can be used in daily activities. The results of this study indicate that rice husk-based catalytic converter has the potential to be an environmentally friendly solution without significantly compromising vehicle performance.
