Abstract
Cucumber tree leaf extract is organic materials that can be use as inhibitor to reduce corrosion rate of low carbon steel on hydrochloric acid. The using of cucumber tree leaf extract is can be expected to be one of inhibitors which is safe, friendly environment and biodegradable and also can reduce the using of synthetic inhibitors. Cucumber tree leaf inhibitors have been chosen as organic inhibitors because it is containing antioxidant that can be reduce corrosion process like tannin. Weight loss method is used to test the effectiveness of cucumber tree leaf extract as an inhibitor on low carbon steel sized 4cmx2,6cmx0,24cm with various concentration of corrosive medium ((HCl 1M, 2M, 3M, 4M and 5M) and period of immersion test (1 week, 2 weeks, 3 weeks, 4 weeks and 5 weeks). The result of research showed that total of tannin in cucumber tree leaf extract is 0,3577%. The most effective of cucumber tree leaf extract is using on hydrochloric acid 1M solution with immersion test 1 week and efficiency 83,6660%. Key words : Corrosion, , 77,9% Zinc plat, Gambir leaf, tannin, inhibitor corrosion.
