Synthesize carbon black pigment from empty fruit bunch as a colorant for printing ink.

Empty Palm oil fruit bunch (EPOFB) are one of the palm oil processing industrial wastes that are abundantly available in Indonesia but are not optimally used. This study aims to synthesize carbon black pigments from EPOFB using the co-precipitation method. The synthesized Carbon black was then characterized by SEM EDX to determine particle size and find out the chemical elements contained in it. The test results showed that the particle size of carbon was in the form of flakes with elemental composition, about 76.8% Carbon, 22.9% Oxygen, and the rest was silicon element. The carbon black resulting from this study has the potential to be used as a black pigment for printing ink. [ABSTRACT FROM AUTHOR]
