Abstract

Casting is a process of melting metal until it melts and then poured in the mold until it freezes. In this study aluminum (Al) from used piston was used as casting raw material and added with magnesium. This research was conducted at the Jember Polytechnic Automotive Engine Laboratory and the Banyuwangi State Polytechnic Mechanical Engineering Laboratory. The method used in this study is an experimental method with variations in the addition of magnesium by 3%, 5%, and 7%. The highest tensile test results were found in specimens with the addition of magnesium by 7%, namely 33.06 N / mm2 with a strain of 0.56%. In addition, the addition of magnesium can affect the stress, this can be known by statistical analysis using the regression method.
