“…The formation of amorphous silica is due to the presence of a silanol group (Si-OH) on its surface. Meanwhile, crystalline silica is formed due to the presence of inorganic impurities that are still attached or do not dissolve during acidification (21).…”

Background: Oil palm shell is a waste of oil palm plants that can be used as a source of silica gel because it contains SiO2. This study aims to determine the oil palm shell silica gel can be used as an active ingredient in the manufacture of body scrubs. Method: This study uses active ingredients with various concentrations of 2,5%, 5%, and 10%. The process of making silica gel starts with ashing, washing, making a sodium silicate solution, and adding NaOH. The preparation test includes an organoleptic test, homogeneity test, pH test, dispersibility test, adhesion test, irritation test, dead skin cell removal test, and stability test. Results: From the results of this study, the SiO2 content of palm oil shell silica gel is as much as 43% with XRF testing, and XRD results at an angle of 2ϴ=22,93º. The FTIR results showed the presence of a Si-OH group at a wave number of 3439.08 cm -1, a Si-O-Si group at a wave number of 1020,34 cm -1, and a -OH group at a wave number of 806,25 cm -1. The preparations that have been made meet the physical evaluation of the preparations, namely in the form of semi-solid, white color, and smells of oleum citri. Each homogeneous preparation, pH with a value ranging from 4,7 to 6,5, does not irritate the skin, meets the requirements of the spreadability test and adhesion test, has poor stability because the pH value has increased and decreased, has a good keratin content value, and the stability test of the formula against temperature at pH showed significant results (p>0.05). Conclusion: This research concludes that palm oil shell silica gel can be formulated as an active ingredient in making body scrubs and has the effect of removing dead skin cells on the skin.

“…Dari hasil penelitian, rasio mol SiO2/Al2O3 terlihat tidak berpengaruh terhadap kristalinitas karena kristalinitas produk zeolit yang dihasilkan relatif sama yaitu pada rentang 74-78%. Ukuran kristal yang kecil menyebabkan jarak antarpartikel menjadi kecil, sehingga struktur kristal yang terbentuk semakin rapat [27]. Hasil penelitian menunjukkan bahwa produk zeolit NaP yang dihasilkan tergolong sebagai nanokristal dengan ukuran <100 nm.…”

Red mud is a bauxite industrial waste of reddish-brown mud with high alkalinity. Red mud has relatively high silica and alumina content, so it can be utilized as a raw material in the synthesis of zeolite. This study aims to synthesize high-purity NaP zeolite from red mud at various SiO2/Al2O3 mole ratios. The synthesis begins with neutralizing the red mud, followed by decomposition using the alkaline fusion method at a ratio of red mud:NaOH = 1:1 (w/w). The filtrate produced by the alkaline fusion was adjusted to the mole ratio of SiO2/Al2O3 = 2.0; 2.5; 3.0; and 4.0, respectively, by adding sodium silicate, followed by a hydrothermal process using an autoclave at 120oC for 16 hours. The synthesized zeolites were characterized using XRD and FTIR spectrophotometry. The XRD results showed that the zeolite produced in all variations of the SiO2/Al2O3 mole ratio studied was a type of high-purity NaP with no other zeolite crystalline phases found as impurities. The structure formed is tetragonal with a degree of crystallinity of 74.54%; 76.47%; 78.94%; 75.64%, and crystal size 80.2286; 54.3437; 37.7099 and 40.1226 nm for zeolite with SiO2/Al2O3 mole ratio 2.0; 2.5; 3.0; and 4.0, respectively. Based on the results of the study, pure NaP zeolite can be synthesized from red mud material using the hydrothermal method at the ratio of moles SiO2/Al2O3 = 2.0 – 4.0.
