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.
