“…Identification of the constituent components of kaolin minerals is done by comparing the peak position of diffraction intensity (2θ) of the sample with the standard peak position of diffraction intensity (2θ) on the Joint Committee for Powder Diffraction Standards (JCPDS). 22 Based on XRD analysis results, it can be seen that Jaboi kaolin consists of kaolinite minerals shown at 2θ ( o ) = 21.52 with d spacing 4.125 23 , quartz at 2θ ( o ) = 21.82 with d spacing 4.068 and cristobalite at 2θ ( o ) = 35.9 with d spacing 2.49. 24 From the diffraction intensity of the three minerals, quartz is the mineral with the largest composition, followed by the minerals kaolinite and cristobalite.…”

“…Based on the results of the micrographs show that hexagonal platelets of the mineral kaolinite with a non uniform size, in addition to the presence of quartz and cristobalite impurities. 19,22,25 701 µm. Impurity minerals, both quartz and cristobalite, are seen in the form of chunks that cover the mineral kaolinite.…”

In this study studied the physical and chemical properties of natural kaolin originating from Jaboi village, Sukajaya district, Sabang City, Aceh province, Indonesia. Natural kaolin deposits in this province are quite large and can be used as raw materials in various industries such as paints, ceramics, rubber medicines and others. Therefore, the study of the physical and chemical properties of natural kaolin through characteristic tests is very necessary so that its utilization in related industries can be optimized. The characteristic tests carried out include XRF, XRD, FTIR, SEM EDX and DSC/TGA where the results of the analysis obtained will be compared with the characteristics of commercial kaolin. Based on the XRF test, the main composition of Jaboi kaolin was obtained as follows: SiO 2 (silica) and Al 2 O 3 (alumina) respectively at 84.8% and 2.96%, while the remaining impurities with concentrations below 1%. XRD diffractograms identify quartz as the main mineral followed by kaolinite and cristobalite. These results are in accordance with the functional groups of FTIR spectra. The SEM test obtained the typical morphology of Jaboi kaolin, in the form of a heterogeneous group of layered hexagonal sheets and EDX results showing the composition of Jaboi kaolin elements consisting of 31.94% silicon, 1.33% aluminum 14.61% carbon and 50.78% oxygen. Based on the derivatogram in thermal analysis, there is no visible crystallization of the Jaboi kaolin. The results of all the characterizations of Jaboi kaolin show that Jaboi kaolin is very suitable for use in the refractory and ceramics industries.

“…Penelitian ini menggunakan metakaolin untuk membentuk sampel komposit zeolit-geopolimer dan geopolimer. Metakaolin diperoleh dari hasil kalsinasi kaolin pada suhu sekitar 550-950 °C sehingga terjadi dehidroksilasi dan membentuk struktur baru (Sunardi et al, 2020). Prekursor kaolin yang digunakan berasal dari Bangka Belitung, Indonesia.…”

Indonesia merupakan salah satu produsen industri tekstil terbesar di Asia Tenggara. Produksi barang tekstil yang tinggi dan kurang memadainya proses pengelolaan limbah cair tekstil membuat Indonesia menjadi negara dengan limbah cair industri tekstil terbesar di Asia Tenggara. Salah satu teknik pengelolaan limbah pewarna yakni dengan menggunakan bahan adsorben seperti zeolit. Pada penelitian ini, zeolit dikompositkan dengan geopolimer dan dibentuk menjadi granul agar memiliki kemampuan adsorpsi dan ketahanan yang tinggi. Komposit disintesis dengan mencampurkan zeolit, metakaolin, dan natrium silikat (Na2SiO3), kemudian dikeringkan dalam oven pada suhu 100 °C selama 2 jam. Sampel-sampel yang digunakan kemudian diuji adsorpsi pada metilen biru. Prekursor sampel dikarakterisasi menggunakan XRD serta SEM. Hasil pengujian adsorpsi menunjukkan bahwa komposit granul zeolit-geopolimer memiliki kemampuan adsorpsi sebesar 52,68 mg/g untuk granul kecil dan 20,85 mg/g untuk granul besar sehingga dapat diaplikasikan pada lingkungan perairan.
