BAB V KESIMPULAN 5.1 Kesimpulan Berdasarkan pada penelitian yang telah dilakukan, dapat diambil kesimpulan bahwa suhu fusi mempengaruhi pembentukan zeolit A dari abu layang. Semakin meningkat suhu fusi maka kristalinitas padatan yang dihasilkan semakin menurun. Pada penelitian ini didapatkan bahwa suhu fusi yang terbaik untuk mensintesis zeolit A adalah 450 °C. Kelarutan Si, Al terbanyak, kristalinitas yang tertinggi, nilai kapasitas pengikatan kalsium (CBC) yang tertinggi serta produk yang dihasilkan merupakan zeolit A murni didapatkan pada suhu fusi 450 °C. Hasil sintesis zeolit A pada suhu fusi 450 °C yaitu: kapasitas pengikatan kalsium (CBC) sebesar 448,19 meq/100 g. Sedangkan pada suhu fusi 400, 500, 550 °C produk yang dihasilkan merupakan zeolit A bersama dengan faujasit dan pada suhu fusi 600, 650 °C produk yang dihasilkan adalah amorf. 5.2 Saran Perlu dilakukan studi lebih lanjut mengenai metode yang sesuai untuk mereduksi kandungan besi pada abu layang batubara awal serta pengaruh waktu aging terhadap sintesis zeolit A sehingga didapatkan kristalinitas yang lebih baik.
