    Empty fruit bunch (EFB) are the second-highest waste produced in the oil palm industry which is 18 022 tonnes in a year. However, the presence of oil palm waste especially from empty fruit bunch (EFB) give a major problem to the disposal. Herein, EFB waste has been identified as a potential carbon source for synthetic graphite production. This is due to implement the lower heating temperature of synthetic graphite produced in controlled heating conditions. Several parameters have been manipulated to study the effect of various parameters on the graphitization process. Hence, in this study, the effect of soaking time towards graphitization of empty fruit bunch (EFB) waste has been investigated. EFB waste was heat treated with various soaking times which is 2 hours, 2.5 hours and 3 hours in controlled heating conditions with constant heating temperature at 500°C and heating rate at 10°/minute After heating treatment, the samples were characterized using X-ray Diffraction (XRD) and analyzed by X'Pert Highscore Plus software. The functional group of synthetic graphite was determined by using Fourier Transform Infrared spectroscopy (FTIR). The morphological study was carried out by using Scanning Electron Microscope (SEM). From the analysis, the best synthetic graphite produced is at the 2.5 hours soaking time with a constant heating temperature at 500°C and a constant heating rate at 10°/min.

    Previously, synthetic graphite was produced at higher heating temperature, which is above 2500°C in complex processing method and by using petroleum coke, anthracite, and coal tar pitch as the starting materials. These materials are known as non-waste sources. Therefore, in this study, Empty Fruit Bunch Waste (EFB) has been identified as a potential carbon source from waste to replace the non-waste sources of starting materials for synthetic graphite production. Hence, by implementing a controlled heating condition via pyrolysis process, with fixed heating rate and soaking time, Empty Fruit Bunch Waste (EFB), was heated at 3 different series of heating temperatures, which are, 300°C, 400°C and 500°C. The heating rate applied was maintained at 10°/min and the soaking time used 3 hours. After the heating treatment, the synthetic graphite obtained was characterized by various analytical tools, including, X-Ray Diffraction (XRD) analysis, Scanning Electron Microscope (SEM) analysis, and Fourier Transform Infra-Red (FTIR) Analysis. Based on the analysis, it was confirmed that synthetic graphite was successfully synthesized by heat treatment at 500 °C with 10°/min of heating rate and 3 hours soaking time. Synthetic graphite was observed in the form of amorphous carbon based on the XRD diffraction pattern that matches with the reference code of 00-041-1487.
