    Abstract

    The purpose of this study is to determine the effect of variations in the type of mold and the addition of dry cell powder marks on the porosity results remelting of Al-Si piston-based scars with 9% Si.This study used three different types of mold there were wet sand mold, dry sand mold and metal mold. Variations addition of dry cell powder is used as much as 0,30%, 0,50% and 0,70% by weight. Data obtained by calculating the porosity on each specimen and taking macro photos. From the calculated porosity created graphs to analyze. This research method using descriptive analysis. The results of this study show that the highest porosity occurs in the variations wet sand mold and additions powder dry cell by weight as much as 0.50% porosity by 3,1447%. The lowest porosity occur in variations metal molds and adding powder dry cell as much as 0,70% by the porosity of 0,1635%. Trought macro photos, metal mold can product smooth surface than sand mold. By this research, the use of metal molds can produce castings with a smooth surface and low porosity. In addition dry cell powder 0,30% and 0,50% led to increased porosity, while the addition cell dry powder 0,70% can reduce the porosity in castings results. This happens in all kinds of molds. Keywords:, porosity, dry cell powder, Al-Si, piston used
