Jackfruit Peel Extract as Environmentally Safe Inhibitor for Carbon Steel Protection in Acidic Solution

The addition of corrosion inhibitors into the acidic environment is an environmental modification to control rate corrosion. Organic compound become environmentally friendly alternative. In this study, research and analysis have been carried out on jackfruit peel extract as a inhibitor for AISI 1037 carbon steel protection in 1M HCl solution. Variation concentration 200-3000 ppm. Corrosion measurements were performed by applying weight loss potential polarization methods. concentrations up 1000 ppm increased efficiency 90.98%, but decreased at 2000 3000 adsorption that occurred study was physical adsorption. It followed Langmuir isothermal fungsional group film layer surface indicated jack fruit compounds adsorbed surface.
