“…Namun beberapa diantaranya juga mensintesis silika dari biomassa seperti daun bambu, sekam padi, tongkol jagung, dan ampas tebu [4]. Selain biomassa beberapa penelitian juga menggunakan pasir yang memiliki kandungan silika yang kemudian dimurnikan untuk memperoleh silika kristal maupun amorf [1], [5][6][7].…”

“…Selanjutnya komposisi senyawa oksida ditampilkan pada Tabel 2, dimana senyawa SiO2 menjadi yang paling dominan yaitu sebesar 98,1 %, sedangkan senyawasenyawa oksida lain kurang dari 1 %. Sebagai pembanding, persentase SiO2 pasir pantai Citra lebih tinggi dibandingkan dengan pasir pantai Sepanjang (49,19%), pasir pantai Parangtritis (54,24%), pasir pantai Glagah (13,00%) [6], pasir Bancar, Tuban (76,80%) [5], dan mendekati kandungan pasir silika pulau Belitung (99,42%) [8]. Hal ini memberikan gambaran bahwa pasir pantai Citra memiliki kandungan SiO2 yang sangat tinggi bahkan sebelum diberi perlakuan apapun.…”

Analisis komposisi unsur, senyawa oksida, dan fasa pasir pantai Citra, Kabupaten Sukamara berhasil dilakukan. Proses identifikasi komposisi unsur dan senyawa oksida menggunakan XRF, sedangkan identifikasi fasa menggunakan analisis XRD. Analisis XRF menunjukkan bahwa Si dan SiO2 mendominasi komposisi unsur dan senyawa oksida masing-masing sebesar 95,6% dan 98,1%. Selain itu, analisis kualitatif pola XRD menunjukkan bahwa SiO2 pada pasir pantai Citra adalah kuarsa. Hasil ini memberikan informasi bahwa pasir pantai Citra memiliki potensi yang sangat baik sebagai sumber SiO2.

“…Beach sand is an example of carbonate sand with a silicon dioxide content of 72-84% [5], though the silica composition varies depending on the geographical location. Parangtritis beach sand, located in Yogyakarta, Indonesia, abounds with silica [6]. For this reason, this research used silica extracted from Parangtritis beach sand as a material to synthesize mesoporous silica catalysts.…”

“…This paper studied the synthesis of mesoporous silica from Parangtritis beach sand as a Ni-supported catalyst. The synthesis was done using a dodecyl-amine (DDA) template by sol-gel method, chosen for its relatively fast processing time, in addition to its lowtemperature requirement, among other syntheses in the research study by Salamah et al and Thahir et al [6][7]. The nickel was then impregnated using the wet impregnation method with variations of nickel content weight of 1, 5, and 10 wt.%.…”

Mesoporous silica (MS) supported by nickel was synthesized from Parangtritis beach sand and assessed for its activity and selectivity as catalysts in hydrocracking waste cooking oil into biofuel. The synthesis of MS was done by the sol-gel method. Ni/MS catalysts using Ni weight variations of 1, 5, and 10 wt.% were denoted as Ni/MS1, Ni/MS5, and Ni/MS10 and were compared to standard mesoporous silica (Ni/SBA-15). The catalysts were characterized using FTIR, XRD analysis, N2 gas sorption analysis, SEM-EDX, and TEM. Catalyst Ni/MS1, Ni/MS5, Ni/MS10, and Ni/SBA-15 have specific surface areas of 130.5, 195.9, 203.9, and 381.2 m2/g and the average pores of 12.30, 9.80, 11.12, and 8.70 nm, respectively. The hydrocracking was run four times to evaluate the catalyst reusability. The hydrocracking WCO has 95.8, 82.4, and 85.2%, respectively. While Liquid fractions produced were 38.8, 43.2, and 50.2 wt.%, each of which contains gasoline of 37.09, 39.76, and 44.27 wt.%, Ni/MS10 has the highest liquid products of 50.2 wt.% and was selective to gasoline fractions up to 44.27%. Therefore, the catalyst synthesized from Parangtritis beach sand is selective for gasoline-fraction hydrocarbon and has hydrocracking activity up to 4 runnings.

High content of silica in beach sand can be synthesized into mesoporous silica (MS) using the sonochemistry method with dodecyl-amine (DDA) as a surfactant template. The preparation began by adding sodium silicate dropwise to DDA solution under the rotation speed of 120 rpm. The mixture was then added with H 2 SO 4 and sonicated at 37 Khz at a temperature of 35 ºC for 20 minutes. The product was then filtered, washed, and dried at 50 °C then calcined at 600 ºC for 5 h. After it was calcined, the sample was characterized by using FTIR, Surface Area Analyzer, XRD, SEM, and TEM as well as the acidity using pyridine vapor adsorption. The synthesized MS was then used as a catalyst in hydrocracking waste cooking oil in a semi-batch stainless steel reactor system at 450 ⁰C for 2 h, under 20 ml min -1 H2 flow rate. The hydrocracking product of the liquid fraction was analyzed using GC-MS. The results showed that the best performance of the MS1 was produced by using the DDA concentration of 0.1 M, had optimum acidity at 1.7 mmolg -1 , specific surface area of 233 m 2 g -1 , total pore volume of 0.4cc/g, and average pore diameter of 7.70 nm.The best MS1 catalyst produced liquid fraction with yield of 31.13 wt.% which consisted of 11.10 % diesel oil and 5.04 % gasoline.
