The design of the manganese mineral powder experiment on carbon steel began with the desire to see the phenomenon of Ferro (Fe) and manganese (Mn) metal atoms with the help of high-temperature heat. This phenomenon is tried by using a pack carburizing using manganese mineral powder and using an air conditioner for the extraction process. This research also deals with the pyrometallurgical process. The research method used is a true experimental design and factorial experimental methods. After calculating the ANOVA in a factorial experiment, the hardness of the steel can be known because it is influenced by the holding time factor and its interactions, namely the temperature and composition of the coal. The purpose of this study is to produce a hardness value in accordance with the formation of manganese content on the surface of carbon steel. After the Scanning Electron Microscope (SEM) test, it appears that the surface morphological changes in the steel are rougher than the original object and the Energy Dispersive X-ray Spectroscopy (EDX) test forms the composition of the steel alloy on the surface.
