Abstract

Fabriesite synthesis from natural minerals sourced from Gowa Regency has been successfully carried out using the hydrothermal method. This study aims to optimize the utilization of local mineral resources as raw materials for synthetic zeolite production. The synthesis process involved mixing activated natural minerals with NaOH solution, followed by hydrothermal treatment at 170°C for 72 hours. The resulting samples were characterized using Fourier Transform Infrared Spectroscopy (FTIR) and X-ray Diffraction (XRD). FTIR analysis revealed characteristic absorption bands of fabriesite, including those -OH stretching, H–O–H bending,  asymmetric Si–O–Si and Si–O–Al stretching, symmetric Si–O–Si and Si–O–Al stretching, and Si–O and Al–O bending. Meanwhile, the XRD analysis confirmed the formation of fabriesite through the appearance of diffraction peaks at 2θ = 20,17°, 26,13°, 30,16°, and 34,39°, which match the standard fabriesite pattern (JCPDS). These results indicate that natural minerals from Gowa Regency have strong potential as a source of silica and alumina for the synthesis of fabriesite-type zeolite, which can be applied in various industrial fields, including catalysis.
