## Abstract
Abstract Corrosion is a complicated problem in everyday life. Corrosion causes many losses because it reduces the life span of metal-based goods or buildings. One solution is to use organic corrosion inhibitors. Organic corrosion inhibitors are an alternative choice because they are more environmentally friendly. Heteroatomic organic compounds containing nitrogen, oxygen, or sulfur in molecules such as those found in MSG, papaya leaves and aloe vera can be used as organic corrosion inhibitors, because they can be well adsorbed on metal surfaces. Amino acids such as glutamic acid which have two carboxylic groups and one amine group are expected to be able to inhibit corrosion by adsorbing metal (iron) surfaces. This study aims to determine the use of MSG, aloe vera and papaya leaves as alternative materials for organic corrosion inhibitors. The results showed that the rust level using MSG solution was 8.33%, aloe vera extract was 9.09%, papaya leaf extract was 8%, and the container with a mixture of aloe vera extract, papaya leaf extract and MSG was added 4.35 %. This shows that aloe vera extract, papaya leaf extract and MSG can be used as an alternative to organic corrosion inhibitors.
