Abstract
Abstract: Corrosion is a gradual destruction of metal, which decrease the quality (degradation) of metal because of their reac-tion with environment by chemical or or electrochemical in us-age time. Extract of belimbing wuluh leaves (Averrhoa Bilimbi) is an organic substances that can be used as a natural inhib itor because it contains tannin that reduce corrosion rate of mild steel in corrosive medium. Tannin in extract of belimbing wuluh leaves is analyzed with two phase, first is qualitative analyze (discoloration from brown to green) and second is quantitative analyze and obtained the tannin level is 0.3924%. Weight loss method is used to test the effectiveness of extract belimbing wul-uh leavesas an inhibitor on metal mild steel sized 4 cm x 2,1 cm x 0,2 cm with various of corrosive medium (such as rain water, swamp water, and river water) and corrosion rate test (1 week, 2 weeks, 3 weeks, 4 weeks and 5 weeks). The result of research showed that usage of extract belimbing wuluh leaves as natural inhibitor is more effective in rain water corrosive environment with corrosion rate test in 5 weeks with efficiency 91%. Index Terms: Belimbing wuluh leaves, tannin, natural corro-sion inhibitor, corrosion, mild steel
