Coconut is one of the industrial plants that plays an important role in the Indonesian economy. The part of coconut that has a high economic value is the coconut shell. This study aims to see the maximum temperature of the coconut shell pyrolysis reactor and to examine the spectrum pattern of charcoal purified using the activation of hydrochloric acid (HCl), acetic acid (CH3COOH), nitric acid (HNO3) and hot water (H2O). The process steps are pyrolysis process carried out at a temperature of ± 310 °C for 2 hours and activation using 4 types of solvents with different acidity levels, soaking for 12 hours. Infrared spectra pattern testing using Fourier Transform Infrared (FTIR). The results of the pyrolysis process produce charcoal, liquid smoke, tar and condensed gases. The spectral pattern of each purified charcoal was analyzed using Fourier Transform Infrared (FTIR). The results of the analysis showed that the spectral pattern of activated charcoal showed a spectral pattern with a low level of impurity absorption, namely the spectral pattern of charcoal using HCl activator at a concentration of 2 M.
Key words: Spectra pattern / coconut shell charcoal / activation / FTIR
