The purpose of this study was to (1) Studying the effect of adding the powder dry cellmarks the porosity defects result from remelting of Al-Si piston waste scrap, (2) Study theeffect of adding the powder dry cell marks of violence result from remelting of Al-Si pistonwaste scrap, (3) Study the percentage improvement in dry powder degasser cell as analternative to get the product to the remelting of Al-Si piston material defects former withminimal porosity.This study used an experimental method that uses a single independentvariable factors (variations addition of powdered dry cell) and two-factor variable (porosityand hardness). Objects in this study using the results of remelting of Al-Si piston waste exwith Si content of 9%. Data analysis techniques in this study using descriptive data analysis.Input parameters in analyzing the data include: the addition of powdered dry cell variation(0%, 0.10%, 0.15%, 0.20%, and 0.30%), porosity test, photo macro structure, and violence.In this study, the addition of the powder has not found the percentage of used dry celloptimized to minimize porosity. The results showed that the remelting of Al-Si piston formerwaste occurs at 0.6909% porosity. Gas porosity increasing as a percentage of dry cellpowder was increased to 0.30 wt% Al. Highest porosity occurs in the addition of the formerpowder dry cell weight as much as 0.30% Al with porosity of 1.6226%. Based on thestructure of the macro picture shows a pore porosity. Gas porosity is caused by H2O gas. Inthe former there is a dry cell powder elements as much as 4.85 wt% H2O. Former cell drypowder only serves as hygroscopic moisture flux which acts as a binder impurities into slag.Visual condition of the specimen shows the addition of a former dry cell powders affect thecleanliness of the molten metal slag (slag) so that the surface becomes smooth look. Formerdry cell powder affect the increased hardness value. Hardness value increases with theaddition of powdered dry cell percentage of the weight of the former al. The increaseaveraged 6.21%. This is because the elements of C as much as 2.76% by weight in the d rycell powder.

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 3rd ? 7th 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.
