Abstract
Batubara merupakan bahan utama untuk pembakaran pada PLTU. Sawdust dan sampah merupakan salah satu kandidat yang dapat mengganti batubara untuk mengurangi emisi rumah kaca. Peneliti melakukan uji korosi temperature tinggi pada ASTM A516 70 dalam lingkungan sawdust dan sampah pada temperature 600ºC dan 700°C dan dengan variabel 100% sawdust, 85% sawdust, 70% sawdust, 50% sawdust. Pada penelitian ini ASTM A516 70 dimasukkan ke tengah sawdust dan sampah pada cawan keramik dipanaskan menggunakan muffle furnace untuk mengetahui ketahanan ASTM A516 70 sebagai lapisan dinding boiler pada pembakaran sawdust dan sampah. Variasi temperature yang digunakan pada penelitian ini adalah 600°C dan 700ºC dan juga variabel persen massa sawdust dan sampah yang digunakan pada penelitian ini adalah 100% sawdust, 85% sawdust, 70% sawdust, 50% sawdust. Kemudian dilakukan uji
karakterisasi untuk mendapatkan beberapa analisi yaitu analisis profil kinetik korosi, morfologi FE-SEM, dan XRD. Berdasarkan hasil uji karakterisasi didapatkan bahwa pengaruh temperatur dapat mengakibatkan penambahan massa dan ketebalan produk korosi dari material tersebut dan juga pengaruh dari pertambahan persen massa sampah dapat mengakibatkan penambahan massa dan ketebalan produk korosi. Produk korosi tersebut disebabkan oleh klorin yang semakin bertambah seiring pertambahan variasi komposisi sampah dan juga pertambahan suhu.

Coal is the main ingredient for combustion in PLTU. Sawdust and waste are candidates that can replace coal to reduce carbon emissions. Researchers conducted high temperature corrosion tests on ASTM A516 70 in an environment of sawdust and garbage at temperatures of 600ºC and 700°C and with the variables 100% sawdust, 85% sawdust, 70% sawdust, 50% sawdust. In this study ASTM A516 70 was put into the center of the sawdust and waste in a ceramic cup heated using a muffle furnace to determine the resistance of ASTM A516 70 as a lining for the boiler wall in sawdust and waste burning. The temperature variations used in this study were 600°C and 700ºC and also the variable mass percent of sawdust and waste used in this study were 100% sawdust, 85% sawdust, 70% sawdust, 50% sawdust. Based on the results of the characterization test, it was found that the effect of temperature can result in an increase in the mass and thickness of the corrosion products of the material and also the effect of increasing the percent mass of the waste can result in an increase in the mass and thickness of the corrosion products. The corrosion product is caused by chlorine which increases as the composition of the waste increases and the temperature increases.
