Abstract: Aluminum alloy type 5083 or AA5083 is suitable for marine applications because of its characteristic. A smart approach to overcome this problem by introduced the existence of inhibitor where it works by retarding the rate of corrosion by forming a surface layer as it protect any metal from reacting to the environment. This study was using a plant extract (henna) which is 600ppm, 700 ppm, 800ppm, 900ppm and 1 OOOppm are use. Aluminium was cut into 25mm x 25mm x 3mm and was polish manually using 600, 800 and 1200 grit of emery paper. Henna was extracted using a solvent which are ethyl acetate using rotary evaporator (Rotavap). To investigate the content of each extraction, a Fourier Transform Infrared Spectroscopy (FTIR) device was used. The corrosion behavior was investigated using several methods which were weight loss measurement, potentiodynamic polarization measurement, electrochemical impedance spectroscopy (EIS) and scanning electron microscope (SEM). Calculation of inhibition efficiency, IE (%) for weight loss, polarization resistance, corrosion current density and corrosion rate.
