Pack carburization process generally performed in the laboratory and use xthe electric furnace or furnace fuel coal briquettes and wood charcoal. These furnace still has some shortcomings. Operating costs are expensive and relatively large size of the constraints so that not everyone can do this pack carburization. <br /> <br /> <br /> <br /> <br /> In this study, the authors wanted to design a pack carburizing furnace that can be used in the household kitchen so everyone can make pack carburization. This furnace is designed in a simple and uses inexpensive materials and easy to obtain. The furnace is designed to use LPG fuel. Furnaces are expected to achieve and stable at temperatures above 850 oC. After performing the design, these furnace can be made. Later, tests conducted on the furnace to determine the characteristics of the resulting temperature. Tests carried out using two types of stoves. Temperature furnaces used Stove # 1 is not achieved termperatur above 850 oC, and only reached 785 oC. While the temperature of the furnace using a burner # 2 reaches temperatures above 850 oC and stable at around 878 oC so that appropriate and can be used for pack carburization. <br /> <br /> <br /> <br /> <br /> Testing is then performed with the carburization process. Specimens used in the form of low carbon steel nails. This pack carburization using carburization media such as charcoal and coconut shell skin energizer 30% wt Mussel Blood that is heated in the furnace for 60 minutes. Then proceed with the quench hardening to obtain an increase in surface hardness. After going through a second process, obtained a significant increase in hardness of the nails. The highest hardness at the surface of the nail reaches 925 <br /> <br /> <br /> <br /> <br /> HV. Hardness is still higher in comparison with previous studies that use coal briquettes furnace with same specimen which only reaches 780 HV highest hardness.
