Aluminum is a non-ferrous metal that is light, strong and resistant to air and water corrosion. Due to the dangerous impact of using aluminum material on the environment, the waste produced by aluminum is recycled. In this research, the casting and molding of the research material was AA6061, which is a mixture of aluminum and coconut shell charcoal powder. The mixing and molding method is casting. After casting, the research sample manufacturing stage is carried out, some of the material that has frozen in the mold is removed, then the material is sawn into powder form, then the iron powder cleaning process is carried out using a magnet, after that the powder is collected which will then become a research sample. Research sample then put it in a plastic clip and given information according to its composition, then tested using a Thermogravimetry Analyzer (TGA). The tool used is TG/DTA exstal SII 7300 located at UPT. Integrated Laboratory and Innovation Center, University of Lampung. The purpose of TGA testing is to measure changes in the mass of research samples with increasing temperature to calculate the activation energy that each sample has when undergoing oxidation. The results of the test are displayed in graphical form and data in Microsoft Excel, then data processing will be carried out. It is known that the solidus point and melting point of the added material have influenced the heating of the material, namely decreasing the solidus point and melting point. The mass addition during the oxidation process reached 140 μg in the temperature range of 300-900°C for AA6061 without the addition of coconut shell charcoal. Meanwhile, for the addition of 12.5 grams of coconut shell charcoal, the temperature range was between 23.71°C to 334.9624°C, there was a decrease of 121.1482 μg. Likewise, for AA6061, with the addition of 25 grams of coconut shell charcoal at a temperature range of 24.08991°C to 360.8733°C, the mass decrease increased by 113.6975 μg.
