PENGARUH JUMLAH IGNITION BOOSTER PADA KABEL BUSI DAN PENAMBAHAN METANOL DALAM PREMIUM TERHADAP KONSUMSI BAHAN BAKAR PADA YAMAHA MIO SPORTY TAHUN 2007

The purpose of this research is: (1) To know the influence of total ignition booster on the sparkplug cable to fuel consumption on Yamaha Mio Sporty 2007, (2) To know the influence of methanol addition in premium gasoline to fuel consumption on Yamaha Mio Sporty 2007, (3) To know the interaction of total ignition booster on the sparkplug cable and methanol addition in premium gasoline to fuel consumption on Yamaha Mio Sporty 2007. This research used experimental methods and the types of quantitative research. The population of motorcycle Yamaha Mio Sporty 2007. The study sample is a Yamaha Mio Sporty 2007 motorcycle with police number AD 2113 ER, engine number 5TL840397 and chassis number MH35TL0067K83947. Sampling technique used Purposive Sampling technique. Experimental design was factorial design AxB, the A total Ignition Booster are without Ignition Booster, use 1 Ignition Booster, and use 2 Ignition Booster, while the B variations of methanol additions are 0%, 20%, and 40% and so there are 9 treatment, each treatment is to replicate as much as three times that obtained 27 data. Data of fuel consumption had been obtained from measurement fuel consumption during 10 minute. Data of analysis used two-way analysis of variance (Anova), which are the prerequisite tests previous performed tests of normality (Liliefors test) and tests of homogeneity (Bartlett test). Then performed multiple comparison tests (Scheffe test) is done. Based the research can conclude that: (1) There are a influence of total ignition booster on the sparkplug cable to fuel consumption on Yamaha Mio Sporty 2007. This is shown by the results of data analysis that Fobs = 190.12 greater than Ftabel = 6.01 level of significance at 1%. (2) There are influences of methanol addition in premium gasoline to fuel consumption on Yamaha Mio Sporty 2007. This is shown by the results of data analysis that Fobs = 691.12 greater than Ftabel = 6.01 level of significance at 1%. (3) There are influence interactions between total ignition booster on the sparkplug cable and methanol addition in premium gasoline to fuel consumption on Yamaha Mio Sporty 2007. This is shown in the results of data analysis which that the Fobs = 10.50 greater than Ftabel = 4.58 level of significance at 1%. Minimum fuel consumption is 2.43 ml/minute, obtained from 2 ignition booster with methanol addition in premium at 20%. Keywords: Ignition Booster, methanol addition, fuel consumption
