This study aims to determine the norit structure (Activated carbon) of coconut shell charcoal test results using Fourier Transform Infrared (FTIR) analysis, X-Ray Diffraction (XRD) and thermal reactions through analysis of Differential Scanning Calorimeter (DSC) and get norit (carbon active) from coconut shell charcoal with high purity X-Ray Fluorescence (XRF) analysis which can be applied as in the pharmaceutical field. The research method consists of 3 stages: (1) preparation of coconut shell charcoal, (2) synthesis of activated carbon, and (3) testing of activated carbon products. The results of FTIR analysis showed a decrease in impurity elements, XRD analysis showed semi crystalline structural activated carbon, DSC analysis showed thermal reaction with exothermic peaks at a temperature of 112.44 C, and XRF analysis showed impurities namely Cl, K, Ca, Px, and Fe.
