Nanoparticles CaCO3/MgO by variation percent weight of MgO (5, 21, 22, 23, 24, and 25) wt.% potentially antibacterial can be synthesized by mixing methods and calcination at temperature 800 oC, which synthesis CaCO3 from shellfish (Anadara granosa) using carbonation methods by flow velocity of CO2 gas 2.8 liters/min. The successful nanoparticles were characterized by BET, antibacterial activity and PSA. Variation percent weight of MgO was used to determine pore size, surface area and antibacterial activity on nanoparticles CaCO3/MgO. The results showed that the weight percent variation of MgO has a different pore size and surface area that is included in the mesoporous category. CaCO3/MgO (5wt.%) has the smallest surface area (3.24 m2/g) and the largest pore size (20.12-29.35 nm), while CaCO3/MgO (24wt.%) has the largest surface area (65.05 m2/g) and the smallest pore size (3.23-3.59 nm) by the closed end of the curve.
