This study discusses the composition of the material contained in the used piston material and compares the strength value of each variation of Ti-B percentage by violence testing. The method used in metal casting is Gravity Casting which uses only gravity of the earth. In the manufacture of this recycled piston includes several stages of the process of working method with Sand Casting mold and its test. Among them are pattern planning, raw material preparation, pattern making, pasri printing,doi:10.18196/jqt.010105 fatcat:xqkumo4t4zdgphmy4itjv4enwy
