Pemanfaatan Ekstrak Daun Tembakau sebagai Inhibitor Korosi pada Logam Baja Karbon dan Aluminium

Adhi Setiawan, Novi Eka Mayangsari, Denny Dermawan

Abstract

Ekstrak daun tembakau dapat dimanfaatkan sebagai inhibitor korosi pada logam baja karbon dan aluminum di dalam larutan HCl. Penelitian ini bertujuan menganalisis pengaruh konsentrasi ekstrak daun tembakau terhadap laju korosi serta efisiensi inhibisi korosi logam baja karbon dan aluminium di dalam media larutan HCl 0,1 M. Laju korosi logam baja karbon dan aluminium dianalisis menggunakan metode polarisasi linear. Hasil penelitian menunjukkan bahwa peningkatan konsentrasi ekstrak daun tembakau dapat menurunkan laju korosi pada logam baja karbon dan aluminium. Laju korosi minimum baja karbon dan aluminium terjadi pada konsentrasi inhibitor sebesar 700 mg/L yaitu masing-masing sebesar 0,940 mm/y dan 0,807 mm/y. Peningkatan konsentrasi inhibitor menyebabkan peningkatan efisiensi inhibisi korosi baja karbon dan aluminium. Hasil SEM menunjukkan bahwa peningkatan konsentrasi inhibitor menyebabkan proteksi korosi semakin tinggi sehingga tingkat degradasi permukaan logam akibat korosi semakin rendah.
