- Study on the growth of carbon crystal produced from coconut shell has been conducted. This research was aimed to study the effects of PVA as stimulant agent in the from of either powder or solution on structural growth of carbon crystal and its physico-chemical properties and the effect of temperature (1000-1500oC) on the characters of the carbon. Several carbon technologies, such as calcinations, mixing and sintering at high temperature, were carried out by employing charcoal produced from coconut shell as the raw material and PVA as the stimulant. Several methods characteristics were performed including Fourier Transform Infrared (FTIR) spectroscopy to determine the functional groups of the carbon. X-ray diffraction (XRD) to identify the structure of carbon crystal, Scanning Electron Microscopy-Energy Dispersive Spectroscopy (SEM-EDS) to analyze the topography of surface and to analyze the component of material and Differential Thermal Analysis � Thermogravimetry (DTA-TG) to study the thermal reaction of the carbon material. In addition, analysis of physical properties was also conducted to study the physico-chemical properties of charcoal and the crystal of carbon material. The product characteristics of carbon material showed that there was a change on the physico-chemical properties of the raw material which has been sintered at 1000 oC, at which coke was produced in this process. Fabrication process at 1500 oC in the presence of PVA gave carbon material from charcoal amorphous to carbon with semi-crystalline structure.
