Abstract
A successful preliminary study was conducted to examine the characteristics of activated carbon derived from yellowfin tuna fishbone using the carbonization method due to its ease and efficiency. Surface morphology and elemental composition analysis of activated carbon was performed using SEM-EDX, while XRD techniques were used to determine crystalline properties and the impact of carbonization temperature on material properties. The study findings indicated a strong correlation between carbonization temperature and the morphology and crystallinity of activated carbon. The surface morphology of carbon samples carbonized at 600 ^{o}C had higher impurity concentration compared to those synthesized at 700 ^{o}C and 800 ^{o}C. However, increasing the temperature resulted in a rougher surface formation. The XRD analysis revealed that an increase in carbonization temperature up to 800 oC contributed to higher carbon crystallinity due to better alignment of carbon chains, leading to a reduction in spacing between planes and the removal of disorganized carbon.
