BAB VKESIMPULAN

Berdasarkan hasil penelitian, dapat diambil kesimpulansebagai berikut. Perlakuan leaching dengan rasio 45 dapatmenaikkan kadar SiO2 serta menurunkan kadar Fe2O3 secarasignifikan yang besarnya berturut–urut 51,3% dan 23,99%.Penurunan CaO pada rasio 15, 45, 25 dan 55 secara berurutansebesar 1,195; 1,69; 1,78 dan 1,84 %. Difraktogram XRD darizeolit A hasil sintetik menggunakan abu layang dengan rasio 15,25, 45 dan 55 menunjukkan puncak karakteristik denganintensitas masing–masing 1723,22; 2252,36; 2571,67 dan2649,31 serta kristalinitas masing–masing 65.04 %, 85.01 %,97.06 % dan 100 % sehingga dapat dikatakan bahwa semakinmeningkat rasio semakin meningkat kristalinitas zeolit A yangdiperoleh.
