The population of the motor vehicles, including a motorcycle in the world has been growing from year to year. It also has been linked to the increase of pollution to the ambient air due to the gaseous and particulate emissions, such as PM1.0, PM2.5 or fine particle, PM10 or coarse particle, SOx, NOx, and many other forms. As a need to clean the air, it is important to develop a filtration system of particulate matters that is applied in a motor vehicle exhaust system. In this research, the electrostatic filters were made of aluminum plates as anodes and cathodes in order to create an electric field. The voltage was varied of V1 (100 Volt), V2 (200 Volt), V3 (300 Volt), and V4 (400 Volt). These filters were installed on the motorcycle exhaust system and tested for 30 minutes. Coarse particle (particulate matter with the diameter less than 10 µm) concentrations before and after passing through the electrostatic filter were measured using a Nova PM Sensor model SDS011 and a microcontroller. The results show that the filter efficiency is a time and voltage-dependent. The highest efficiency (58%) was obtained at the voltage of 400 Volt, V4. On the other side, V1 generated the lowest efficiency (5%).
