title = "Langmuir adsorption isotherm analysis on the addition of Myrmecodia Pendans extract as a corrosion inhibitor with a variety of corrosive media",
abstract = "In this study, the corrosion process was done by potentiodynamic polarization method on API 5L Grade B. Variations corrosion media used were NaCl 3,5%, HCl 1 M and H2SO4 1 M. Organic Inhibitors used are plant Myrmecodia Pendans, while the concentration of the extract used were 100-500 mg / L (multiples of 100 mg / L). In this study, the mechanism of adsorption equation model used is Langmuir. This study aims to determine appropriate corrosive media followed the Langmuir adsorption isotherm when added to extracts of Myrmecodia Pendans as a corrosion inhibitor. The value of free energy of the system have obtained from the adsorption isotherm models. With the known value of free energy, it can be seen whether the adsorption occurs in physics or chemistry. This relates to the surface protective layer formed on the surface adsorption extract. The results showed that the corrosion in 3.5% NaCl solution that follows the Langmuir method.",
