Due to its low carbon content, mild steel is prone to corrosion. Therefore, corrosion inhibitors are needed to decrease the corrosive rate of mild steel. This research aims to investigate the influence of adding potassium iodide to miana leaves extract (Coleus scutellaroides (L.) Benth.) (MLE) on the corrosion rate of mild steel, identify the type of adsorption, synergistic effects and characterize the surface of mild steel both before and after the addition of potassium iodide. The weight loss method is employed to test the corrosion rate, and the type of adsorption is identified through thermodynamic calculations. Surface characterization is evaluated using Fourier Transform Infrared (FTIR) and Scanning Electron Microscopy (SEM). As potassium iodide is added, the weight loss findings show an increase in inhibitory efficiency. When potassium iodide concentration was 0.4 g/L and temperature was 30°C, the maximum inhibitory efficiency was attained, which was 92.784%. Characterization analysis indicates the interaction between potassium iodide and MLE with the surface of mild steel. This research has not been explored yet and is expected to provide information on the use of potassium iodide and MLE as environmentally friendly corrosion inhibitors.

Hal ini menegaskan bahwa EDM dapat mengurangi laju korosi dengan membentuk lapisan pelindung di permukaan baja lunak (Emriadi et al, 2021). Hal ini mengindikasikan bahwa senyawa dari EDM telah teradsorpsi pada permukaan baja lunak dan membentuk lapisan pelindung yang berfungsi untuk mencegah korosi (Zaher et al, 2022).…”

[Corrosion Inhibition of Mild Steel with Miana (Coleus scutellaroides (L.) Benth.) Leaves Extract in HCl Medium] Penelitian ini bertujuan untuk mengetahui pengaruh penambahan ekstrak daun miana (Coleus scutellaroides (L.) Benth.) (EDM) terhadap laju korosi baja lunak, mengidentifikasi jenis adsorpsi, dan mengkarakterisasi permukaan baja lunak baik sebelum maupun setelah penambahan EDM. Metode kehilangan berat (weight loss) digunakan untuk menguji lajuÂ korosi, jenis adsorpsi diidentifikasi melalui perhitungan termodinamika, dan karakterisasi permukaan dievaluasi dengan menggunakan fourier transform infrared (FTIR), X-Ray Diffraction (XRD), dan Scanning Electron Microscopy (SEM). Hasil penelitian menunjukkan bahwa laju korosi terendah didapatkan pada suhu 30â„ƒ dengan konsentrasi EDM sebesar 6 g/L sebesar 0,153 mg/cmÂ²jam dengan efisiensi inhibisi 88,288%. Analisis karakterisasi menunjukkan adanya interaksi antara EDM dengan permukaan baja lunak. Penelitian ini diharapkan dapat memberikan informasi terhadap penggunaan EDM sebagai inhibitor korosi yang ramah lingkungan.
