Abstract
The Graphite made from coconut shell waste have been fabricated and characterized. Coconut shell waste is obtained from two different locations, first in the lowland area with sea water environment and the second area is in the highland with fresh water environment. The sample was dried by two different methods which by oven and solar thermal process. After drying process, the sample was carbonized at 600°C for 3 hours using programmable furnace. Subsequently, the sample was washed with hydroflouride (HF) to reduce the impurity content of the sample. The graphite based on coconut shell were characterized using X-Ray Diffraction (XRD) to determine the phase percentage of graphite, Fourier Transform InfraRed (FTIR) to find the functional groups and Scanning Electron Microscopy (SEM) to represent the surface morphology of the graphite.
