The research on the effectiveness and characterization of quartz sand/coconut shell charcoal composite as adsorbent of Manganese (Mn) heavy metal has carried out. Quartz sand was previously activated by using Na2CO3 while the coconut shell charcoal was activated by using HCl 4 M. The adsorbent characterization was carried out by Fourier Transform Infrared Analyzer (FTIR), X-RayDiffraction (XRD), Scanning Electron Microscopy-mapping Energy Dispersive X-Ray (SEM-EDX), and Surface Area Analyzer (SAA). The adsorption experiment of the Mn metal was carried out by varying the composition of quartz sand/coconut shell charcoal. The variations were in the number of 100:0, 0:100, 25:75, 50:50, 75:25 (b/b) at the degree of pH 1-6 and contact time 10, 15, 20, 30, 45, 60, 75, and 90 minutes by using batch method. The measurement of final concentration at the equilibrium phase was carried out by using AAS. The optimum adsorption condition of the Mn metal occurred in the comparison of quartz sand/coconut shell charcoal 50:50 (b/b), the best condition at the degree of pH 5, contact time during 30 minutes with adsorption capacity of 0.56 mg/gram. The type of adsorption isotherm of composite quartz sand/coconut shell charcoal adsorbent towards the metal of Mn followed the Freundlich isotherm theory.
