This research focuses on corncob waste as activated carbon. The matrix of tapioca (starch) is used as adhesive. The objective of this research is to compare the results of engine exhaust emission, power, and torque of vehicle with and without AC made of corncobs. The utilization of AC classified into two types of composition namely corncob and starch with 80:20 and 70:30. It arranged on the intake air filter bound and neatly to absorb nitrogen from the air so that pure oxygen burned in the combustion chamber. The results show that the AC reduces the percentage of CO, HC, CO2, O2, and AFR at various engine rotation. It also influences power and torque of vehicle performance. The result shows that AC slightly effect the performance. It decreases the torque at 70:30 composition. The main conclusion can be drawn that AC from corncobs greatly affects exhaust emissions in vehicles.
