- The objectives of this research are to investigate: (1) the effect of the use of two sparking plugs on the CO exhaust emission of Motorcycle Yamaha Jupiter Z assembled in 2009; (2) the effect of engine rotation on the CO exhaust emission of Motorcycle Yamaha Jupiter Z assembled in 2009; and (3) the simultaneous effect (interaction) of variation of number of sparking plugs and that of engine rotation on the CO exhaust emission of Motorcycle Yamaha Jupiter Z assembled in 2009. This research used the experimental research method with the factorial design of 3 x 3. It was conducted at the Office of Transportation, Communication, and Informatics at Jl. Menteri Supeno No. 7 Manahan,Surakarta. The population of research was Motorcycle Yamaha Zupiter Z assembled in 2009 with the engine number of 30C653165 and the chassis number of F8034661I. The sample of research was taken by using the purposive sampling technique. The data of research were gathered through the measurement of CO exhaust emission by using exhaust gas analyzer. They were taken in three times of replication, and therefore there were 18 data. The data were analyzed by using the two way analysis of variance and then the Scheffe and Chi-square tests. Prior to the tests, they were exposed to pre-requisite tests, namely: normality test and homogeneity test. The former used Lilliefor test and the latter used Bartlett test. The results of research are as follows: 1) There is an effect of the use of two sparking plugs on the CO exhaust emission level of Motorcycle Yamaha Jupiter Z assembled in 2009. The use of two sparking plugs reduces the CO exhaust emission level. 2) There is an effect of engine rotation on the CO exhaust emission of Motorcycle Yamaha Jupiter Z assembled in 2009. The higher is the engine rotation, the higher the CO exhaust emission level is. 3) There is a simultaneous effect (interaction) of variation of number of sparking plugs and that of engine rotation on the CO exhaust emission of Motorcycle Yamaha Jupiter Z assembled in 2009. Such a treatment also results in a lower CO exhaust emission level. 4) The lowest exhaust emission level as much as 5% is obtained in the use of two sparking plugs.
