Abstract. Coal is a deposit composed of organic and inorganic materials. The organic material comes from plant remains that have undergone various levels of decay (decomposition) and changes in physical and chemical properties before and after being covered by other deposits. The inorganic materials in coal consist of various minerals that form as fine materials dispersed within the coal or accumulate into thin layers (Sutardji, 2009). Fly ash, also known as coal ash, is a byproduct of coal combustion. It is a fine powder produced when coal is burned and can be used as a raw material in various industries, such as construction and manufacturing. Fly ash consists of oxides, including silicon dioxide, aluminum, iron, and calcium oxide. Fly ash has several beneficial properties, including high strength, low permeability, and resistance to chemical attack. Fly ash is commonly used as a supplementary cementitious material in concrete and can also be used as a filler in asphalt, plastic, and paper products. Additionally, fly ash can be used as a raw material to produce zeolites and adsorbents. This research aims to analyze the main elements in fly ash by conducting XRF analysis. The XRF test seeks to determine the main minerals present in fly ash, with the compounds analyzed being SiO2, Al2O3, Fe2O3, CaO, MgO, Na2O, K2O, TiO2, P2O5, MnO, SO3, H2O, and LOI. A total of 6 samples were tested, with sample codes A, B, C, D1, D2, and D3.
Abstrak. Batubara adalah endapan yang tersusun dari bahan organik dan non organik. Bahan organik berasal dari sisa tumbuhan yang telah mengalami berbagai tingkat pembusukan (dekomposisi) dan perubahan sifat-sifat fisik serta kimia baik sebelum maupun sesudah tertutup endapan lain di atasnya. Bahan non organik pada batubara terdiri dari macam-macam mineral yang terbentuk sebagai material-material halus yang menyebar pada batubara atau terkumpul menjadi lapisan-lapisan tipis (Sutardji, 2009). Abu batubara, juga dikenal sebagai fly ash, adalah produk sampingan dari pembakaran batubara. Ini adalah bubuk halus yang dihasilkan ketika batubara dibakar, dan dapat digunakan sebagai bahan baku di berbagai industri, seperti konstruksi dan manufaktur. Abu batubara terdiri dari campuran oksida, termasuk silikon dioksida, aluminium oksida, besi oksida, dan kalsium oksida. Abu batubara memiliki sejumlah sifat yang bermanfaat, termasuk kekuatan tinggi, permeabilitas rendah, dan ketahanan terhadap serangan kimia. Abu batubara biasanya digunakan sebagai bahan pengganti semen dalam beton, dan juga dapat digunakan sebagai bahan pengisi dalam aspal, plastik, dan produk kertas. Selain itu, abu batubara dapat digunakan sebagai bahan baku dalam produksi zeolit dan adsorben. Penelitian ini bertujuan untuk menganalisis unsur utama yang berada di abu batubara dengan melakukan analisis XRF. Pengujian XRF bertujuan untuk mengetahui mineral utama yang terdapat didalam abu batubara, senyawa yang di analisis yaitu SiO2; Al2O3; Fe2O3; CaO; MgO; Na2O; K2O; TiO2; P2O5; MnO; SO3; H2O; HD. Jumlah sampel yang dilakukan pengujian sebanyak 6 sampel dengan kode sampel A, B, C, D1, D2, dan D3.
