Abstract
Penggunaan energi tak terbarukan akan mengakibatkan beberapa dampak pada lingkungan, salah satunya ialah pemanasan global. Salah satu faktor utama penyebab pemanasan global adalah emisi karbon yang dihasilkan oleh pembangkit listrik tenaga uap (PLTU). Salah satu solusi untuk mengurangi emisi karbon dari PLTU adalah menggunakan metode co-firing. Metode co-firing ini menggunakan sampah dan biomassa berupa sawdust. Namun metode co-firing dapat mengakibatkan korosi pada dinding boiler PLTU. Tujuan penelitian ini adalah untuk menganalisis mekanisme korosi, menganalisis pengaruh variasi persen massa sampah (100%, 85%, 70%, dan 50%) dengan penambahan sawdust, serta menganalisis pengaruh variasi temperatur (600°C dan 700°C) pengujian pada material dinding boiler PLTU yaitu ASTM A516 grade 70. Penelitian ini menggunakan metode benam garam sebagai metode pengujian korosi. Analisis yang dilakukan meliputi analisis profil kinetik korosi, morfologi FE-SEM EDS dan XRD. Berdasarkan penelitian ini, pengujian korosi menghasilkan produk korosi pada sampel, yang ditunjukkan dengan pertambahan massa dan bagian permukaan yang semakin tebal, mengalami perubahan warna, dan terbentuk spalasi. Variasi 100% sampah memiliki laju pertambahan massa tertinggi. Serta temperatur 700°C memiliki laju pertambahan massa tertinggi

The use of non-renewable energy will have several impacts on the environment, one of which is global warming. One of the main factors causing global warming is carbon emissions produced by steam power plants (PLTU). One solution to reduce carbon emissions from PLTU is using the co-firing method. This co-firing method uses waste and biomass in the form of sawdust. However, the co-firing method can cause corrosion on the boiler walls of the PLTU. The purpose of this study was to analyze the mechanism of corrosion, to analyze the effect of variations in the mass percent of waste (100%, 85%, 70%, and 50%) with sawdust addition, and to analyze the effect of variations in testing temperatur (600°C and 700°C) on the PLT boiler wall material, namely ASTM A516 grade 70. This study used the salt immersion method as a corrosion testing method. The analyzes carried out included analysis of the corrosion kinetic profile, FE-SEM EDS and XRD morphology. Based on this research, corrosion testing produces corrosion products in the sample, which is indicated by the mass increase and the surface area getting thicker, changing color, and forming spallation. The 100% waste variation has the highest mass increase rate. And the temperatur of 700°C has the highest mass increase rate
