Abstract

Corrosion is a decrease in the quality of metal due to electronic reactions with its environment or in general it is better known as rusting. When viewed from a chemical perspective, corrosion is a metal reaction that is in direct contact with the environment and oxygen. Corrosion cannot be eliminated, but it can be controlled. So controlling the corrosion rate using organic or inorganic based corrosion inhibitors is appropriate. This research used grade 5L carbon steel pipes and looked at the effect of water hyacinth extract on the corrosion rate. In this research, it was proven that water hyacinth extract contains tannins and saponins which can inhibit the optimal corrosion rate at an extraction temperature of 85ºC. The SEM test in this study showed that the steel pipe samples immersed in the corrosion inhibitor medium had a smoother surface compared to the corrosion medium without inhibitors.

Abstract

Corrosion cannot be avoided, and its presence is a concern in the chemical industry as it can disrupt processes, mainly because process equipment is commonly made of steel pipes. This necessitates the control of corrosion rates using corrosion inhibitors, whether organic or inorganic. The use of organic inhibitors is more environmentally friendly as it does not produce negative impacts on the environment, requires low costs in procurement, and is simpler in its treatment processes. One potential organic inhibitor is the extract from red dragon fruit peel waste. The extract is obtained through the maceration extraction process using 96% ethanol with temperature variations of 80, 85, and 90 ℃. Subsequently, sample immersion is carried out in seawater and rainwater medium. The results of this research indicate that red dragon fruit peel extract contains flavonoids and saponins that can optimally inhibit the corrosion process at an extraction temperature of 85 ℃. SEM tests show that metal samples immersed in the corrosion medium with the inhibitor have a smoother surface compared to those in the
