Abstract

Ekstrak dari kulit dalam semangka telah dipelajari sebagai inhibitor korosi pada tinplate dalam larutan 2% NaCl menggunakan metode pengurangan berat dan polarisasi potensiodinamik. Pada penelitian ini digunakan variasi konsentrasi ekstrak. Hasilnya memperlihatkan bahwa efisiensi inhibisi semakin meningkat dengan meningkatnya konsentrasi ekstrak, nilai maksimum sebesar 99,97% pada konsentrasi ekstrak kulit dalam semangka 600 mg/L yang didapat dari metode polarisasi potensiodinamik. Kedua metode yang telah dilakukan tersebut memberikan pola inhibisi yang sama. ===================================================================================================== The extract of watermelon rind has been studied as a corrosion inhibitor for tinplate in 2% NaCl solution using potentiodynamic polarization and weight loss methods. In this study used various concentration of extract. Results obtained show the efficiency increased with increase in concentration of extract, the maximum value of 99,97% at watermelon rind extract concentration 600 mg/L studied from potentiodynamic polarization. Both of these methods have been carried out giving the same pattern of inhibition.
