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°C, 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.
