Pembuatan Green Inhibitor Dari Ekstrak Teh Dan Kopi Dengan Metode Sokletasi Pada Baja Karbon

---

ABSTRACT
Corrosion is a degradation of metals quality caused by chemical reaction between
metal and its ambient. The used of green inhibitor is a natural methods to control
the corrosion rate of metal. The objective of this research is to count the efficiency
of green inhibitor from tea and coffee extract, to find which variable that affect
the most of corrosion rate of mild steel, to determine the best concentration of
extracts to control the corrosion rate of mild steel. The extraction methods is
Soxhletation method with solvent rasio 1 : 4 of ethanol : aquadest. Weight loss
method is used to determine the rate of corrosion with 0,5;1;1,5 g/l variance of
inhibitor concentrations and 3, 6, 9, 12 days contact times. The lowest corrosion
rate is 61,27 mpy at 1,5 g/l of tea extract inhibitor solution with 9 days contact
times and the highest efficiency is 79,02% at 1,5 g/l of tea extract inhibitor
solution with 12 days of contact times.
Keywords: coffee, green inhibitor, soxhletation, tea extract.
