Ekstrak Daun Salam (Syzgium Polyantha L) Dengan Metode Soxhlet Sebgai Inhibitor Korosi Pada Baja Karbon Astm A36 Dalam Media Krosoi Naoh Dan Hcl

ABSTRACT
Corrosion is defined as the result of damage from a chemical reaction between a metal and its
environment. The use of inhibitors is one way to inhibit the corrosion rate. Bay leaf extract is an
organic material that can be used as an inhibitor. The purpose of this study was to determine the
effect of adding bay leaf extract on the corrosion rate of ASTM A36 carbon steel in 0.5 M HCL
and 1 M NaOH corrosive media. This study used variations in the concentration of bay leaf
extract 0 grL/, 1.5 gr/L, 2.0 g/L and 2.5 g/L. The extraction method used was socletation with a
ratio of ethanol : distilled water 1: 3 and immersion time of 24 hours, 36 hours, 48 hours and 60
hours. To determine the content of tannins which acts as a corrosion inhibitor, a fourier
transform infrared spectroscopy, phytochemical and UV-VIS spectro were performed. The
effectiveness of using bay leaf inhibitors is known through the weight loss test. FTIR test results
show that the bay leaf extract contains tannin compounds which can inhibit the corrosion rate
that occurs in ASTM A36 carbon steel when used as a corrosion inhibitor. The best efficiency
occurred at a concentration of 2.5 g / L with a soaking time for 60 hours in a 0.5 M HCL
solution of 82%.
Key words: bay leaf extract, carbon steel, corrosion rate, inhibitor efficiency
