Abstract

Telah dilakukan sintesis zeolit dari abu dasar batubara menggunakan metode peleburan alkali hidrotermal dengan KOH sebagai aktivator. Konsentrasi KOH yang digunakan adalah 0,1 mol, 0,3 mol dan 0,5 mol. Peleburan alkali dilakukan pada temperatur 550 oC selama 1 jam dan proses hidrotermal dilakukan pada temperatur 100 oC selama 6 jam dengan variasi media kristalisasi aquades dan air laut. Sampel hasil sintesis dicuci dengan aquades hingga mencapai pH 9-10. Zeolit yang dihasilkan dikarakterisasi menggunakan XRD. Hasil karakterisasi menunjukkan bahwa zeolit yang terbentuk menggunakan media kristalisasi aquades adalah potassium aluminum silicate (megakalsilit), leucit, muskovit dan masih banyak kandungan  kuarsa. Sampel yang disintesis menggunakan media kristalisasi air laut mengandung megakalsilit, leucit, muskovit dan sodalit.

Kata kunci: Potassium aluminum silicate, megakalsilit, konsentrasi.
