N2 - The main objective of this research is to investigate the effectiveness of Myrmecodia Pendans (MP) wood extract as Eco friendly Corrosion Inhibitor on corrosion of material API 5L Grade B in 3,5% NaCl solution using potentiodynamic polarization curve, Gas Chromatography- Mass Spectrometer (GC-MS) and Electrochemical Impedance spectroscopy (EIS). MP usually called as "sarang semut" in Indonesia. We analyzed MP in different concentration of extract. By 500, 1000, 1500, 2000 and 2500 ppm. The experiment was started by extraction of the MP. According to the polarization potensiodynamic data, the rate corrosion could be decrease about 90,36% by concentration 500 ppm. In accordance with the data of the EIS, the same concentration of inhibitor produced 92.3% with charge transfer resistance of 595.6 Ω.cm2. It means MP extract could serve as an effective inhibitor for the corrosion. This is consistent with the initial hypothesis that MP contains antioxidant compounds that can inhibit oxidation thereby reducing the corrosion rate.
