Abstract
Telah dilakukan penelitian untuk mengetahui pengaruh perlakuan asam dan kalium permanganatterhadap karakter zeolit alam Tasik. Perlakuan pertama menggunakan KMnO4 dan H2SO4, zeolit denganperlakuan ini disebut Z-22. Perlakuan kedua menggunakan KMnO4, H2SO4 dan HCl selanjutnya disebut Z-33.Sebagai pembanding, dilakukan pencucian dengan akuabides terhadap zeolit alam Tasik selanjutnya disebut Z-11. Karakter yang diuji meliputi perubahan nilai kapasitas tukar kation (KTK), rasio Si/Al, keasaman, hilang padapemijaran dan kristalinitas. Hasil penelitian menunjukkan nilai KTK, rasio Si/Al, keasaman, hilang padapemijaran dan kristalinitas Z-22 meningkat terhadap Z-11. Pada Z-33, hanya nilai hilang pada pemijaran yangmenunjukkan peningkatan sedangkan karakter uji yang lain relatif menurun.
