PENGARUH PENGGUNAAN ELEKTROLISER DENGAN VARIASI DIAMETER KAWAT TEMBAGA DAN VARIASI LARUTAN TERHADAP KONSUMSI BAHAN BAKAR SEPEDA MOTOR HONDA SUPRA-X 125D TAHUN 2007

Abstract

The purposes of the research are to: (1) know effect of electrolyzer application with varied diameters of copper wire on fuel consumption of Motorcycle Honda Supra-X 125D 2007; (2) know effect of electrolyzer application with varied solutions on fuel consumption of Motorcycle Honda Supra-X 125D 2007; (3) know interaction used electrolyzer application with varied diameters of copper wire and varied solutions fuel consumption of Motorcycle Honda Supra-X 125D 2007. The research is a quantitative one with experimental method. Sample of the research is a motorcycle Honda Supra-X 125D 2007 with machine number JB51E2015321. The research was performed on the road test in 3^rd – 7^th km of Prambanan – Piyungan street, Yogyakarta. Data is obtained from amount of fuel consumption of the motorcycle with addition of an electrolyzer tube containing varied diameters of copper wire and varied solutions. The data is listed on tables and presented in form of graphics, and then, they are analyzed. The results of the research indicated that: (1) there was an effect of electrolyzer application with varied diameters of copper wire and varied solutions on fuel consumption of Motorcycle Honda Supra-X 125D 2007. Results of the tests indicated that greater fuel saving was found with smaller diameter of copper wire; (2) The use of the electrolyzer with varied solutions also affected fuel consumption of Honda Supra-X 125D 2007. Results of tests showed that a greater fuel saving was found with the use of a strong alkali solution than the neutral one; (3) There was interaction of the electrolyzer use with varied diameters of copper wire and varied solutions on fuel consumption of Honda Supra-X 125D 2007. It was seen when the electrolyzer used copper wire of 1.5 mm in diameter and KOH solution, the fuel consumption was more efficient. The fuel consumption was 0.0035 liter/km or 18.81% more economical than standard condition.
