The purposes of this research are: (1) To explore the use effect of Electronic Voltage
Stabilizer against consumption fuel Yamaha Mio Soul 2010. (2) To explore the effect of the
variation of spark plugs against consumption fuel on Yamaha Mio Soul 2010. (3) To explore
the interaction effect of Electronic Voltage Stabilizer and variation spark plugs against
consumption fuel on Yamaha Mio Soul 2010.
This research was conducted in the Workshop of Mechanical Engineering, Faculty of
Teacher Training and Education. Sebelas Maret University of Surakarta. Type of this
research is descriptive qualitative uses experimental methods. The Object in this research
used a motorcycle Yamaha Mio Soul 2010 with engine number 2S6439296. Techniques of
data analysis in this research using descriptive data analysis that is directly observed
experimental results are then analyzed and summing up the results of the research. As an
input parameter in analyzing the data include: the use of Electronic Voltage Stabilizer, a
variation of the standard spark plugs, platinum, iridium and fuel consumption.
The research can be conclude that: (1) The use of Electronic Voltage Stabilizer on
Yamaha Mio Soul 2010 to fuel consumption with standard plug of 9.2 ml/minute, platinum
spark plug 9.2 ml/minute, iridium spark plug 8.73 ml/minute. (2) Without the use of Electronic
Voltage Stabilizer on Yamaha Mio Soul 2010 against the consumption of fuel by standard
spark plug of 9.66 ml/minute, platinum spark plug 9.33 ml/minute, iridium spark plug 8.93
ml/minute. (3) The best interaction between the use of Electronic Voltage Stabilizer and
variation of spark plugs that is on the use of Electronic Voltage Stabilizer to the spark plug
with the use of iridium which is 8.73 ml/minute, but the use this variation must attention the
total cost
