“…Analysis of the identification of the surface morphology of fly ash was observed at two variations of magnification values, namely 1000 and 2000 times, with the results of Scanning Electron Microscopy (SEM) showing that the structure's shape is spherical with a regular shape also the more the image is enlarged, the more there is agglomeration at several points. This was also found by Hanum et al [24]. By obtaining the surface morphology of the fly ash, the particle diameter size can also be known, as shown in Figure 4.…”

“…Permasalahan yang akan timbul dari pemakaian batubara sebagai sumber energi adalah abu yang dihasilkan dari pembakaran batubara berupa fly ash dan bottom ash. Fly ash merupakan padatan dari sisa pembakaran batubara yang terbawa bersama gas buang dan ditangkap oleh alat pengendali udara [17]. Bottom ash merupakan padatan dari sisa pembakaran bautubara yang keluar dari dasar tungku boiler [18].…”

“…Pada penelitian sebelumnya, peneliti telah melakukan uji karakteristik untuk coal fly ash dari berbagai jenis pembangkit listrik (Hanum et. al., 2018;Hanum et. al., 2020) dan diketahui silika merupakan salah satu komposisi utama penyusun pada coal fly ash.…”
