Abstract

Corrosion inhibitors are divided into two types, namely organic inhibitors and inorganic inhibitors, the use of inorganic inhibitors has been abandoned in its use due to inorganic inhibitors having toxic and non-biodegradable properties, corrosion that occurs and is not handled will lead to reduced iron quality, collapse of construction, bursting of a pipe due to leaking, and disrupt the flow of fluid in the pipe. Research on organic inhibitors that will be used is the extraction of ketapang leaves because ketapang leaves have tannin compounds that can help slow down the reaction between oxygen and ferrous metal by forming corrosion. The method used is the meseration method, then it will be tested using spectrophotometry to obtain a tannin content of 2.9798 and will then be used as a sample to determine its effect on reducing corrosion in the hope that this study is successful in determining the effect of lignin contained in ketapang leaves on corrosion that occurs in pipes. channel. Based on the results of the research carried out, the highest inhibitor efficiency value in this study was obtained at 72 hours of immersion with a variation of 15 ml ketapang leaf inhibitor with a value of 66.6%. In this study, it was found that the inhibitor efficiency value increased up to 72 hours of immersion and decreased inhibitor efficiency value at 144 hours of immersion, these results indicate that the optimum time for the ketapang leaf extract to withstand the corrosion rate in the pipe slab sample is 72 hours of immersion.
