Abstract
Arabic Gum is known to be used as a corrosion inhibitor, especially in an acidic environment (HCl). This study used 1100 (99%) aluminum metal with variation of 1%, 2%, and 3% arabic gum inhibitors on hydrochloric acid (HCl) concentration medium 0,5M. This study obtained the efficiency of arabic gum inhibitors on aluminum metal against hydrochloric acid (HCl) media of 92.83%. Tests with electrochemical method, obtained the highest current of 4.01 × 10〗 1 cm (- 6) A / cm2 inhibitor and the lowest current of 1.43 × 10〗 3 cm (- 6) A / cm2 inhibitor. In SEM results with 500x magnification showing aluminum surface morphology with 3% immersion inhibitor partly partially well protected area but in certain area begin to form oxide layer and pitting corrosion (Pitting Corrosion). At 5-day immersion the surface undergoes oxidation layer formation as well as uniform corrosion structure based on the duration of the immersion. Keywords: Aluminum, Arabic Gum, Inhibitor, Corrosion Arabic Gum diketahui dapat digunakan sebagai inhibitor korosi, terutama dalam lingkungan asam (HCl). Penelitian ini menggunakan logam alumunium 1100 (99%) dengan variasi inhibitor arabic gum 1%, 2%, dan 3% pada media larutan asam klorida (HCl) konsentrasi 0,5M. Penelitian ini memperoleh efisiensi inhibitorarabic gum pada logam alumunium terhadap media asam klorida (HCl) sebesar 92,83%. Pengujian dengan metode elektrokimia, didapat arus tertinggi sebesar 4,01× 10−6A/cm2 inhibitor 1% dan arus terendah 1,43× 10−6A/cm2 inhibitor 3%. Pada hasil SEM dengan pembesaran 500x menunjukan morfologi permukaan alumunium dengan inhibitor 3% perendaman 1 hari sebagian area terlindung dengan baik namun pada area tertentu mulai terbentuk lapisan oksida dan terbentuk lubang-lubang (PittingCorrosion). Pada perendaman 5hari permukaan mengalami pembentukan lapisan oksidasi serta struktur pemetaan merata (Uniform Corrosion) berdasarkan lamanya waktu perendam.
