Abstract

Sintesis material komposit MCM-41/UiO-66 dilakukan dengan menggunakan pasir zirkon sebagai sumber Zr4+. Material ini mampu bertindak sebagai adsorben dalam proses adsorpsi pewarna metil jingga. Penelitian ini bertujuan untuk memanfaatkan pasir zirkon yang melimpah di Indonesia sebagai bahan dasar dalam sintesis material komposit. Metode penelitian meliputi preparasi pasir zirkon, fusi alkali, leaching HCl, sintesis UiO-66, sintesis MCM-41, dan sintesis komposit MCM-41/UiO-66 dengan variasi massa MCM-41 sebesar 5, 10, dan 15%. Karakterisasi material dilakukan menggunakan X-ray Diffraction (XRD), Fourier Transform Infrared (FTIR), Scanning Electron Microscopy (SEM), dan Adsorpsi-desorpsi Nitrogen (N2). Pola difraktogram XRD pada hasil sintesis menunjukkan puncak karakteristik 2θ yaitu 7,56° pada intensitas tinggi dan 8,68° pada intensitas sedang yang sesuai dengan referensi UiO-66 standar. Spektra FTIR hasil sintesis juga menunjukkan pita serapan pada bilangan gelombang yang sama dengan referensi. Pengujian adsorpsi pewarna methyl orange menunjukkan bahwa komposit MCM-41/UiO-66 memiliki kapasitas adsorpsi maksimum tertinggi sebesar 35,8 mg/g dengan tingkat penghilangan mencapai 89,5% pada waktu adsorpsi optimum 90 menit. Hasil penelitian menunjukkan bahwa material komposit MCM-41/UiO-66 yang dihasilkan memiliki porositas yang tinggi dan luas permukaan yang besar, yang efektif dalam adsorpsi metil jingga. Penggunaan material komposit ini diharapkan dapat menjadi solusi yang efektif dan ramah lingkungan dalam penanganan limbah zat pewarna pada industri tekstil.

The synthesis of MCM-41/UiO-66 composite material was carried out using zircon sand as a source of Zr4+. This material is able to act as an adsorbent in the adsorption process of methyl orange dye. This study aims to utilize zircon sand which is abundant in Indonesia as a basic material in the synthesis of composite materials. The research methods include zircon sand preparation, alkali fusion, HCl leaching, UiO-66 synthesis, MCM-41 synthesis, and MCM-41/UiO-66 composite synthesis with variations in MCM-41 mass of 5, 10, and 15%. Material characterization was carried out using X-ray Diffraction (XRD), Fourier Transform Infrared (FTIR), Scanning Electron Microscopy (SEM), and Nitrogen (N2) Adsorption-desorption. The XRD diffractogram pattern of the synthesis results showed characteristic peaks of 2θ, namely 7.56° at high intensity and 8.68° at medium intensity, which corresponded to the standard UiO-66 reference. The FTIR spectra of the synthesis results also showed absorption bands at the same wave number as the reference. The methyl orange dye adsorption test showed that the MCM-41/UiO-66 composite had the highest maximum adsorption capacity of 35.8 mg/g with a removal rate of 89.5% at an optimum adsorption time of 90 minutes. The results showed that the resulting MCM-41/UiO-66 composite material had high porosity and a large surface area, which effectively adsorbed methyl orange. This composite material is expected to be an effective and environmentally friendly solution for handling dye waste in the textile industry.
