Along with the increasing standard of living of the community, the transportation sector also increased. The high concentration and activity of the population has the potential to cause air pollution problems due to emissions from road transport sector activities. This study aims to determine the use of a combination of gypsum, cement and glue as a exhaust gas filter at 150 cc Satria FU motorbike against HC level emissions and CO and engine performance. This study uses three variations in thickness of gypsum, namely 1 cm, 2 cm and 3 cm with rpm starting idle, 3000 rpm, 4000 rpm and 5000 rpm. From the results of the study it is known that the gypsum exhaust filter with a thickness of 3 cm can reduce CO exhaust emissions by 0.05% in idle conditions, 0.47% at 3000 rpm, 0.41% at 4000 rpm, and 0.35% at 5000 rpm compared to satellite exhaust. In HC exhaust emissions with gypsum thickness of 2 cm at 3000 rpm engine rotation yields 30.7 ppm with conditions not exceeding the permitted exhaust gas emissions limit HC. Gypsum exhaust gas filter with a thickness of 1 cm can increase torque by 4 N-m and engine performance power as much as 12.77 Hp compared to a thickness of 2 cm and 3 cm.
