The residue of oil palm wastes combustion seems a promising silica source and can be recovered through a straightforward method. In this study, the combustion followed by an alkaline extraction method was employed to extract high purity of silica. The oven-dried oil palm decanter cake (DOPDC) was heated at combustion temperatures of 600, 700, 800, and 900°C to produce OPDC ashes (OPDCA), followed by an alkaline extraction using 5M of NaOH solution. Thermogravimetric analysis (TGA) was used to observe the thermal behavior of DOPDC where the suitable combustion temperatures to produce silica ranged between 600 and 1000 �. X-Ray Fluorescence (XRF) analysis showed that silica contents were 31-36 after combustion, increasing to 76.95 after the chemical treatment. Moreover, the spherical shape of the silica was observed through electron microscope analysis. It was represented by the aggregation of silica after going through chemical treatment. The X-Ray Diffraction analysis also proved that the amorphous silica was produced, characterized by the hump-shaped spectrum. The infrared analysis confirmed that the silica had been successfully extracted from OPDCA by the presence of silica functional groups shown in the spectrum. © 2022 Tim Pengembang Jurnal UPI. date: 2023 official_url: https://www.scopus.com/inward/record.uri?eid=2-s2.0-85145037844&doi=10.17509%2fijost.v8i2.53724&partnerID=40&md5=f160d9f1b887c4cb1d69469a6c2cc654 id_number: 10.17509/ijost.v8i2.53724 full_text_status: none publication: Indonesian Journal of Science and Technology volume: 8 number: 2 pagerange: 141-156 refereed: TRUE citation: Rahim, N.A. and Harun, N.Y. and Saeed, A.A.H. and Bilad, M.R.
