ABS (Acrylonitrile-Buadiene-Styrene) plastic is a type of copolymer composed of several forming monomers. ABS have a properties that heat resistant stable, has high strength, has an endurance, hardness, rigidity and is easy to process, clay, hard, can be bonded, corrosion resistant and can be electroplated. ABS plastic is one of the most effective polymers used in industries such as electronics, automotive and household appliances. This study aims to determine and analyze the effect of electrolessplating temperature on physical characteristics including thickness, roughness, and mechanics which include hardness and wear. Electrolessplating methods are used to overcome the disadvantages of ABS plastics. In this study ABS with dimensions of 80 mm in length, 7 mm in width, and 3 mm in thickness was given electrolessplating treatment with nickel coating. The research variable used in this study is the electrolyte temperature variation of nickel coating with variations of 40oC, 50oC, 60oC, 70oC. The test variables carried out are physical characteristics which include micro testing, SEM testing, thickness testing, roughness testing, and mechanics which include hardness testing and wear testing. The results showed that the thickness of the nickel layer increased at 50oC and decreased at 60oC and 70oC.In the roughness test, the roughness of the specimens increased with increasing electrolyte temperature with temperature sequentially 40oC, 50oC, 60oC, 70oC and with a roughness value of 0,170 μm, 0,192 μm, 0,255 μm 0,422 μm.In the hardness test, the hardness value did not increase with the highest hardness value of 84.5 while the hardness value in the raw material was 83.5.While the wear rate of the nickel layer at electrolytic plating temperatures of 40oC, 50oC, 60oC, 70oC in order was 19.01, 13.00, 8.80, and 4.19
