Abstract
This study aimed to analyze the characteristics of Plered clay waste as a raw material for synthesis, investigate the changes in the physical properties of the synthesized material using a combination of the Microwave-Assisted Hydrothermal (MAH) method and conventional heating, and identify the initial indication of zeolite phase formation based on SEM-EDS, FTIR, and XRD characterization. The independent variable was the synthesis method employing the combination of MAH and conventional heating, while the dependent variables were the physical characteristics of the synthesized material, including morphology, elemental composition, functional groups, and crystal structure. The controlled variables included the type of raw material, NaOH concentration, synthesis temperature, and synthesis duration. The study used two specimens, consisting of untreated Plered clay waste and the synthesized material, selected through a purposive sampling technique. Data were analyzed using a descriptive comparative approach based on the characterization results obtained from Scanning Electron Microscopy–Energy Dispersive X-ray Spectroscopy (SEM-EDS), Fourier Transform Infrared Spectroscopy (FTIR), and X-ray Diffraction (XRD). The results showed that the synthesis process altered the material morphology, reduced the Si/Al ratio from 2.48 to 1.59, and introduced sodium (Na), indicating the reorganization of the aluminosilicate framework. FTIR analysis revealed characteristic aluminosilicate absorption bands, while XRD analysis identified new diffraction peaks at 2θ values of 13.9920° and 24.4240°, indicating the formation of a new crystalline phase, although quartz remained the dominant phase. Based on the SEM-EDS, FTIR, and XRD characterization results, it can be concluded that the combination of the MAH method and conventional heating successfully initiated the transformation of the aluminosilicate structure and indicated the early formation of a zeolite phase. However, the obtained evidence was insufficient to confirm the successful synthesis of Zeolite-Y. Therefore, Plered clay waste demonstrates considerable potential as an alternative raw material for zeolite synthesis, although further optimization of the synthesis parameters is required to improve the crystallinity of the resulting material. Keywords: Plered clay waste, Microwave-Assisted Hydrothermal, conventional heating, zeolite. Penelitian ini bertujuan untuk menganalisis karakteristik limbah tanah liat Plered se-bagai bahan baku sintesis, mengkaji perubahan sifat fisik material hasil sintesis menggunakan kombinasi metode Microwave Assisted Hydrothermal (MAH) dan pema-nasan konvensional, serta mengidentifikasi indikasi pembentukan fase zeolit berdasar-kan karakterisasi SEM-EDS, FTIR, dan XRD. Variabel bebas dalam penelitian ini ada-lah metode sintesis menggunakan kombinasi MAH dan pemanasan konvensional, se-dangkan variabel terikat berupa karakteristik fisik material hasil sintesis yang meliputi morfologi, komposisi unsur, gugus fungsi, dan struktur kristal. Variabel kontrol meliputi jenis bahan baku, konsentrasi larutan NaOH, suhu, dan waktu sintesis. Sampel penelitian terdiri atas dua spesimen, yaitu limbah tanah liat sebelum sintesis dan material hasil sintesis yang diperoleh dari limbah tanah liat Plered dengan teknik purposive sam-pling. Analisis data dilakukan secara deskriptif komparatif berdasarkan hasil karak-terisasi menggunakan Scanning Electron Microscopy–Energy Dispersive X-ray Spec-troscopy (SEM-EDS), Fourier Transform Infrared Spectroscopy (FTIR), dan X-Ray Diffraction (XRD). Hasil penelitian menunjukkan bahwa proses sintesis menyebabkan perubahan morfologi permukaan, penurunan rasio Si/Al dari 2,48 menjadi 1,59, serta munculnya unsur Na yang mengindikasikan reorganisasi struktur aluminosilikat. Hasil FTIR menunjukkan pita serapan khas aluminosilikat, sedangkan hasil XRD memper-lihatkan munculnya puncak baru pada sudut 2θ = 13,9920° dan 24,4240° yang mengindikasikan terbentuknya fase kristal baru, meskipun fase kuarsa masih dominan. Berdasarkan hasil karakterisasi tersebut, dapat disimpulkan bahwa kombinasi metode MAH dan pemanasan konvensional mampu menginisiasi transformasi struktur alumi-nosilikat serta menunjukkan indikasi awal pembentukan fase zeolit, namun belum mem�berikan bukti yang cukup untuk menyatakan terbentuknya Zeolit-Y secara sempurna. Limbah tanah liat Plered berpotensi dimanfaatkan sebagai bahan baku alternatif sintesis material zeolit dengan optimasi parameter sintesis lebih lanjut. Kata Kunci : Zeolit, Tanah liat Plered, Microwave-Assisted Hydrothermal, Pemanasan Konvensional.
