Bicycle stem is the link between handlebar (handlebar) with steerer tube (fork). Stem one of the bike parts to
note and Each type of bike is different for the size and specifications stemnya. This research aims to. Obtained
characterization of alumunium casting material as a material for making stem bikes with casting temperature of
700 ° C, and temperature variations of room temperature (30 ° C), 100 ° C, 150 ° C, 200 ° C, and characteristic
hardness values stem between piston waste material and stem. The piston waste is melted at the melting
furnace at a temperature of 700 ° C. then cast into the mold. After obtaining the specimen and then testing the
material characteristics include chemical composition, microstructure, and hardness. The result of the research
after casting with variation of the molded temperture has different material characteristic values, ie: chemical
composition which has no change before and after casting, the microt structure has little porous defect, and the
hardness value where the higher the mold temperature the lower the hardness . Conclusions of data processing
The highest value of piston recycled hardness is 93 HV when compared to the hardness of 61.2 HV stem bike
material, the hardness is more than enough and from the composition test there is a difference of Si 12%
composition. Result of micro structure at foundry with 4 variation still have defect of cast (porous and
shrinkage). the stam bike hardness test has an average hardness value of 64.2 HV whereas for the hardness
value of piston waste casting results show the hardness value of 91 HV with mold temperature 30 ° C, 93 HV
with mold temperture 100 ° C, 89 HV with mold temperature 150 ° C, 87 HV with mold temperature 200 ° C. The
higher the mold temperature, the lower the hardness of the material.
