Perbedaan Abstract The use of gasoline in motor vehicles produced exhaust emissions with various type of elements contained in them. Research has been carried out to identify the elements contained in the exhaust emission of motor vehicles with Laser-generated method Breakdown Spectroscopy (LIBS). Identification is carried out on premium gasoline (RON 88), pertalite (RON 90) and pertamax (RON 92) vehicles. The result data is in the form of spectrum between wavelength and intensity. The spectrum formed from the entire sample shows no differences in the elements identified in premium, pertalite and pertamax gasoline. The difference also lies in the concentration of elemental content in each gasoline fuel. The results of identified spectrum are elements of Carbon (C), Sulfur (S), Hydrogen (H), and Oxygen (O).
