Abstract. Research has been conducted on. The utilization of biomassa as an organic inhibitor in AISI 1020 steel at Lampung University. Samples of carbon steel AISI 1020 were immersed in 3% corrosive medium HCl without being given and given inhibitors of leaf extract jengkol, salam, ketapang and mango 0.8% for 4 and 7 days. inhibitors of leaf extract jengkol, salam, ketapang and mango 0.8% for 4 and 7 days. Calculation of reduction in corrosion rate is carried out by the method of weight loss. The results showed that the addition of Biomasaa inhibitors was effective in reducing the corrosion rate of the samples with the greatest efficiency in the soaking of 7 days of ketapang leaves, which was equal to 74.22%. The results of XRD characterization showed that the phases formed were Fe and Fe2O3 in samples coated with inhibitors and in samples soaked without phase inhibitors Fe2O3 which were corrosion products. The results of SEM characterization showed that the microstructure of the surface of the sample after immersion in the inhibitor contained thin layers overlaying the steel in the sample not coated with the inhibitor, clearly visible cracks and holes indicating that the sample had undergone corrosion. Keywords: Low carbon AISI 1020, corrosion inhibition, HCl, XRD, and SEM-EDS.
