Graphene is a semiconductor material discovered by Andre K. Geim and Kostya Novoselov. Graphene is generally derived from carbon, graphene has a carbon-carbon distance of 0.142 nm. Graphene has several advantages including high thermal conductivity which is able to conduct heat between materials and optimize energy transfer of 5000W/mK, has high electrical conductivity, good optical transparency of 97.7% and is elastic and flexible where the material is quite malleable and has a tensile strength of 1 Tpa. Graphene does not exist in nature purely, but is found in the form of graphite which is the basic material of pencils. To obtain graphene in pure form, an extraction or separation process from graphite (synthesis) is required. In this research, the synthesis used is the arc discharge method. In the testing process, the efficiency level of the circuit is known through power dissipation and voltage drop. The power dissipation during the 2-minute test was Pi=0.214 J/s and during the 5-minute test was Pi=0.35639 J/s. The voltage drop during the 2-minute test was 61.65% while during the 5-minute test the voltage drop was 56,88%. Graphite powder is successfully converted into graphene, this is known by XRD and SEM tests, where during the XRD test it is characterized by a shift and increase in peak points. SEM is characterized by the presence of graphene sheets formed with an average length of 0.408 μm.
