Abstract
THE UTILIZATION OF AVOCADO SEED (PERSEA AMERICANA MILL) AS CORROSION BIOINHIBITOR OF CARBON STEEL Herawati, 2014, 48 Pages, 11 Tables, 17 Pictures, 4 Enclosure Avocado seed (Persea Americana Mil) is part of avocado plant, that is very rarely used and eventually it waste in environment. The using of avocado seed is as row material of bioinhibitor, because avocado seed has some contents such as tannin, N, and P. By extracting avocado seed is used as bioinhibitor. The using of avocado seed ectract as bioinhibitor hopefully can be new alternative and can reduce the using of syntetic inhibitors. In testing the effectiveness of the avocado seed as bioinhibitor corrosion on carbon steel plate use lose weight method. The variable is used in various concentration of corrosion medium (HCl solution 1M, 2M, 3M, 4M, and 5M) and periode of immersion test (1week, 2 weeks, 3 weeks, 4 weeks, and 5 weeks). The resut of research showed that total of tannin in avocado seed extract is 0,203008%. The most effective of avocado seed extract is using on hydrocloric acid 2M solution with immersion test 1 week and efficiency 94,6407%. Key words : Corrosion, low carbon steel, guava leaf, tannin, inhibitor corrosion
