N2 - The use of Myrmecodia Pendans (MP) extract as mild steel corrosion inhibitor in 3.5% NaCl media was investigated using weight loss and potentiodynamic polarization methods as well as characteristics analysis of the Fourier Transform Infra-Red (FTIR). Obtained data from weight loss and potentiodynamic polarization methods has shown the value of inhibition efficiency (% IE) is proportional toadded inhibitor concentration. Tafel constants data indicates that MP extract can act as cathodic and anodic inhibitors (type of mixed inhibitor). FTIR analysis also demonstrates the characteristics of MPextract. Occured inhibition mechanism was in the form of inhibitor adsorption process on metal surfacethat allegedly preceded by physical adsorption followed by chemical adsorption. Chemical adsorption is conceivable since metal surface scoping elevates as the increasing of inhibitor concentration.
