Abstract
Pemanfaatan ekstrak biji semangka sebagai inhibitor korosi
dalam media 2% NaCl telah diteliti. Pada penelitian ini,
digunakan metode pengurangan berat dan polarisasi
potensiodinamik dengan variasi konsentrasi inhibitor. Ekstrak biji
semangka dapat menghambat korosi karena adanya senyawa Lcitrulline
dan senyawa organik lain yang terkandung di dalamnya.
Efisiensi inhibisi maksimum pada metode pengurangan berat
sebesar 89,89% dan pada metode polarisasi potensiodinamik
sebesar 96,45%.

Utilization of a watermelon seed extract as corrosion
inhibitor for tinplate in medium 2%NaCl has been investigated.
This research use weight loss and potentiodynamic polarization
method with various inhibitor concentrations. Watermelon seed
extract can decrease the corrosion because there are L-citrulline
compound and organic molecul others in the extract. Inhibition
efficiency maximum for weight loss method is 89.89% and for
potentiodynamic polarization method is 96.45%.
