“…The highest surface area and an average pore diameter are 385.928 m 2 /g and 6.015 nm for mesoporous silica with 6gr CTAB template. These results indicate that mesoporous character from beach sand was higher than Lapindo mud (the surface area of 75.105 m 2 /g; a pore volume of 0.1974 cm 3 /g and an average pore diameter of 105.14 A) [30] also silica from natural diatomite (the surface area of 38-250 m2/g; pore volume of 0.071-0.364 cm3/g and average pore diameter of 5-8 nanometer) [31].…”

The potential for sand in Indonesia is very abundant because Indonesia has a long coastline than other countries. This research was conducted to explore the potential of beach sand as an alternative raw material to replace commercial silica. To obtain the natural silica, the beach sand was prepared and extracted into mesoporous silica. The reflux method was chosen to extract silica using NaOH solution, HCl solution, and CTAB surfactant. The mesoporous structure was potentially affected by CTAB and SiO2 ratio, and therefore, this research was focused more on the effect of CTAB weight variation (3; 4,5 and 6 g). Several instruments were used to analyze the characteristics of silica, such as Surface Area Analyzer (SAA), Scanning Electron Microscopy (SEM), and Fourier Transform Infrared Spectroscopy (FTIR). The mesoporous silica has siloxane (Si-O-Si) and silanol (Si-OH) functional group and showed a coral reef-like structure. The porosity properties of these materials ranging from 300-385 m2/g for the specific surface area, 5-8.8 nanometer for pore diameter, and 0.4-0.8 cm3/g for pore volume. Optimal CTAB weight found to be at 6 g, which produces the mesoporous silica with a surface area of 385.928 m2/g, an average pore diameter of 6.015 nanometers, and pore volume of 0.579 cm3/g.

Penggunaan silika sering digunakan dalam berbagai industri. Tujuan penelitian ini adalah untuk mengetahui kadar silika pada tanah vertisol di desa Bringinbendo. Penelitian ini dimulai dengan perendaman tanah pada aquadest, kemudian dicuci sebanyak 3 kali dan dikeringkan pada 110°C selama 24 jam. Selanjutnya dihaluskan hingga ukuran 250 mesh. Tahapan kedua yaitu sintesis silika dengan metode ekstraksi alkali dan diikuti presipitasi asam. 20 gram serbuk tanah diekstraksi dalam 100 ml NaOH (3, 5, dan 7M) sambil diaduk dan dipanaskan pada 80°C. Selanjutnya ditambahkan aquadest sebanyak 250 ml dan disaring menggunakan kertas Whatman. Filtrat dititrasi dengan HCl 5M sambil diaduk hingga pH mencapai 7. Suspensi dipertahankan pada temperatur kamar selama 24 jam, disaring, dan dicuci sebanyak 5 kali dengan aquadest kemudian dikeringkan. Hasil dari penelitian yaitu massa silika paling besar terdapat pada konsentrasi NaOH 7M pada waktu 1 jam yaitu 2,59 gram dan tanah vertisol di Desa Bringinbendo memiliki kadar silika dalam kategori sedang dengan persentase sebesar 77,7%.Silica is widely used in industry. The aim of this study was to determine the silica content in vertisol soil in Bringinbendo village. This research was started by soaking the soil in aquadest, then washed 3 times and dried it at 110 ° C for 24 hours. Furthermore, smoothed to 250 mesh size. The second stage is the synthesis of silica using the alkaline extraction method and the treatment of acids. 20 grams of soil powder were extracted in 100 ml NaOH (3, 5, dan 7M) while stirring and heated at 80 ° C. Next, 250 ml of aquadest was added and filtered using Whatman paper. The filtrate was titrated with 5M HCl while stirring until the pH reached 7. The suspension was maintained at room temperature for 24 hours, filtered, and 5 times with aquadest then dried. The results of the mass study were that the greatest silica was found in 7M NaOH concentration at 1 hour, namely 2.59 grams and vertisol soil in Bringinbendo Village had silica content in the medium category with a proportion of 77.7%.

“…Sebagai contoh, pasir pantai dengan kandungan kalsium yang cukup tinggi dapat dijadikan kalsium karbonat (CaCO3) dengan kemurnian yang tinggi, dimana selama ini Indonesia masih mengimpor kalsium karbonat (CaCO3) untuk industri cat, kertas, karet, makanan, kosmetik, dan farmasi [5]. Adapun unsur silicon (Si) yang dapat diperoleh dari silika pasir dapat dimanfaatkan untuk sel surya, bahan semikonduktor, bahan keramik, bahan semen, dan sejenisnya [6]. Adapun unsur besi seperti magnetit (Fe3O4) banyak dimanfaatkan sebagai magnetic recording media, high density digital recording disk, magnetic fluids, data storage, MRI, drug delivery system, biosensor SPR, microwave device dan magnetic sensing [7].…”
