Research on premixed butane combustion has been carried out, to determine the characteristics of flame velocity and ion concentration. The research was carried out by combining premixed butane mixture in a cylindrical combustion chamber measuring 108 mm in diameter and 170 mm in length. The premixed butane air mixture is set at the equivalent composition ratio  = 0.8; 0.9; 1.0; 1.1; 1,2. The results showed that the highest flame speed was equivalent to a ratio of 1.1, which was 198 cm / s whereas the highest radical concentration indicated by the voltage on the ion sensor system is equivalent to a ratio of 1.1, which is 5.5 volts. Keywords: butane, flame velocity, radical concentration, premixed combustion
