Konversi Karbon Menggunakan Metode Plasma Tegangan Tinggi Berbahan Dasar Arang Kayu Bakau

ABSTRACT
Charcoal is the result of the carbonization process of carbon-containing materials
due to decomposition by heat where the charcoal itself can be used as the main
ingredient for making graphene. Plasma arc discharge technology has the
interesting characteristic that the output power can be controlled easily and
precisely by the magnitude of the current. To produce high-voltage plasma with the
arc discharge method, it is done by flowing an electric voltage source of 220V and
using a voltage-increasing transformer to change the source voltage to 10kV which
is then connected to rod electrodes and plate electrodes to produce high-voltage
plasma and conversion of charcoal to graphene will occur. In this study, the
distance between the electrodes greatly affects the graphene yield. Where at a
distance of 1 cm the plasma produced is stronger and the plasma color is bluish
orange, at 1.5 cm the plasma produced is a deep orange plasma color and at 2 cm
the plasma produced is pale orange and the sound is not very strong. The length of
time the carbon is exposed to plasma discharge also greatly affects the 3 minutes
of graphene produced more than 2 minutes and 1 minute, the longer the time the
carbon is exposed to plasma discharge the more graphene is produced after the
carbon is exposed to plasma discharge then XRD analysis is performed to show its
crystallization structure where there is a shift at each peak which is a characteristic
of graphene material, and SEM analysis was carried out to determine the pore
structure of carbon affected by plasma discharge. The more porous, the better the
converted carbon, then the structure is measured where the structure is
micrometer-sized as a feature of the successful conversion of carbon.
