PENGARUH TEGANGAN INPUT PADA ELEKTROLISER DAN WAKTU PENYALAAN (IGNITION TIMING) TERHADAP TORSI DAN DAYA SEPEDA MOTOR HONDA SUPRA X 125 TAHUN 2007

This purposes of this research were: (1) To knew how the effect of input voltage of electrolysers to torque on motor cycle Supra-X 125 year 2007. (2) To knew how the effect of ignition timing to torque on motor cycle Supra-X 125 year 2007. (3) To knew how the interaction between input voltage of electrolyser and ignition timing to torque on motor cycle Supra-X 125 year 2007. (4) To knew how the effect of input voltage of electrolysers to power on motor cycle Supra-X 125 year 2007. (5) To knew how the effect of ignition timing to power on motor cycle Supra-X 125 year 2007. (6) To knew how the interaction between input voltage of electrolyser and ignition timing to power on motor cycle Supra-X 125 year 2007. This research used experiment method. Sample research used was Honda Supra X 125 year 2007 with engine number JB81E1108989. The data obtained from the value of torque and power with variation input voltage from electrolyser 0 volt, 4 volt, 8 volt and 12 volt used ignition timing standard (15° BTDC) and ignition timing progress (18° BTDC) and back (12° BTDC). Data finded from result of the research with anava two ways calculation. Based on this reseach can be conclude: (1) it is significance influence between electrolyser input voltage to torque on motor cycle Supra X 125 year 2007, significance of electrolyser input voltage on 4 volt (2) it was significance influence between variation ignition timing to torque on motor cycle Supra X 125 year 2007, significance of ignition timing when back to 12O BTDC (3) it interaction significance between variation of electrolyser input voltage and ignition timing to torque on motor cycle Supra X 125 year 2007 max torque happen at electrolyser input voltage 12 Volt and ignition timing 15° BTDC. (4) it is not significance influence between electrolyser input voltage to power on motor cycle Supra X 125 year 2007(5) it was significance influence between variation ignition timing to power on motor cycle Supra X 125 year 2007, significance of ignition timing when back to 12O BTDC (6) it interaction significance between variation of electrolyser input voltage and ignition timing to power on motor cycle Supra X 125 year 2007 max torque happen at input voltage electrolyser 12 Volt and ignition timing 18° BTDC
