Abstract
INDONESIA:
Abu sekam padi dihasilkan dari proses pembakaran sekam padi memiliki kandungan silika dengan kadar yang tinggi. Silika dalam abu sekam padi dapat dimanfaatkan untuk bahan baku pembuatan zeolit. Penelitian ini bertujuan untuk mengetahui karakteristik nanozeolit Y dari abu sekam padi dengan variasi suhu hidrotermal.
Ekstraksi silika dalam abu sekam padi dilakukan dengan cara ekstraksi asam basa untuk mendapatkan silika yang lebih murni. Silika hasil ekstraksi dikarakterisasi menggunakan X-Ray Fluorosence (XRF). Sintesis nanozeolit Y dilakukan dengan menggunakan metode sol-gel yang dilanjutkan dengan proses hidrotermal. Sintesis dilakukan dengan penambahan templat organik berupa TMAOH sebagai agen pengarah struktur. Rasio molar SiO2/Al2O3 yang digunakan yaitu 2,5. Komposisi bahan yang digunakan ialah 0,72 (TMA)2O : 0,0094 Na2O : 0,4 Al2O3: 1 SiO2 : 108,82 H2O dengan waktu pemeraman selama 72 jam. Kristalisasi dilakukan selama 48 jam dengan variasi suhu hidrotermal 60, 80 dan 100 °C. Nanozeolit Y hasil sintesis dikarakterisasi menggunakan X-Ray Diffraction (XRD) dan Scanning Electron microscope (SEM) untuk mengetahui keberhasilan sintesis.
Analisis XRF menunjukkan prosentase silika abu sekam padi hasil ekstraksi sebesar 94,7 %. Analisis hasil XRD menunjukkan bahwa sintesis nanozeolit menghasilkan campuran nanozeolit Y dan A. Nanozeolit Y sintesis memiliki kristalinitas tertinggi pada suhu 100 °C. Ukuran kristal nanozeolit Y suhu 60, 80 dan 100 °C berturut-turut 20,92 nm; 93,18 nm dan 40-45 nm. Analisis SEM menunjukkan bahwa semakin tinggi suhu bentuk kristal semakin terlihat jelas membentuk kubus.
ENGLISH:
Rice husk ash was produced by combustion that had content a high quality of silica. It obtained from the rice husk ash be able to be came in useful for standard substance of synthesis zeolite. The objective of this research to comprehend the characteristic of nanozeolite Y from the rice husk ash with variation of hydrothermal temperature.
Extraction of silica in rice husk ash is done by acid-base extraction to obtain a more pure silica. The product of silica extraction was characterized using X-Ray Fluorosence (XRF). Synthesis nanozeolite Y was produced by using sol-gel method and was proceeded by using hydrothermal process. The synthesis was produced by increasing organic template TMAOH as the structure of side-effect agent. Applying molar ratio SiO2/Al2O3 was 2, 5. Applying material composition was 0,72 (TMA)2O : 0,0094 Na2O : 0,4 Al2O3: 1 SiO2 : 108,82 H2O by 72 hours aging time. The crystallization was produced 48 hours with variation of hydrothermal temperature 60, 80 and 100 °C. The product of synthesis nanozeolite Y was characterized by X-Ray Diffraction (XRD) and Scanning Electron microscope (SEM) to determine the success of the synthesis.
The analysis of XRF appearance that the product of silica presentation of rice husk ash was 94, 7 %. The result analysis of XRD showed that nanozeolit synthesis produced compounding nanozeolite Y and A. The nanozeolite Y synthesis had the highest crystallization on temperature 100 °C. The size of crystal nanozeolite Y on temperature 60, 80 and 100 °C in a row 20, 92 nm; 93, 18 nm dan 40-45 nm. The analysis of SEM showed that the higher hydrothermal temperature the crystal shape has become increasingly apparent form a cube.
