Leaf extract gambir (Uncaria Gambir Roxb) is an organic material that can be used as an inhibitor to reduce the corrosion rate of ferrous metals in the medium corrosive sodium chloride 3%. The use of leaf extract of gambir expected to be inhibitors that are safe, enviromentally friendlly and biodegradable and also can reduse that use of synthetic inhibitors. Inhibitors of leaf extract gambier chosen as an organic inhibitor because it contains antioxidants from the group of polyphenols , the tannins . losses weigh method used to test the effectiveness of the leaf extract gambir as acorrosion inhibitor in a metal plate measuring 4cmx1,5cmx0,417cm with variations gambir leaf extract concentration (200 pm, 4000 ppm, 6000 ppm dan 8000 ppm) and long soaking time (2 days, 4 days, and 6 days). The result showed the optimum concentration of inhibitor extract gambir leaves most effectively used in corrosive 3% sodium cholride medium solution is 8000 ppm with a time of immersion 2 days and an efficiency of 694939%.
