“…FA contains some hazardous metals such as Cd, Pb, Ti, and Cr which were accumulated by plants in a dosedependent manner. At lower levels, these metals are accumulated by plants at very low concentrations and below the permissible limit which is safe for human consumption [8,22,42]. However, the use of FA in agroecosystems at higher levels may pose a threat to the soil ecosystem due to the presence of toxic heavy metals.…”

A pot experiment was conducted under net house conditions to study the ameliorative role of different levels of fly ash as a soil amendment, on the growth markers, biochemical attributes, and the antioxidant enzyme activity of beetroot. Seeds of beetroot were sown in earthen pots containing growth substrate, consisting of field soil amended with different levels of fly ash (0%, 5%, 10%, 15%, 20%, and 25% weight/weight). Beetroot grown in 15% fly ash-amended soil had significantly (p ≤ 0.05) higher plant growth and pigment content as compared to the control. With the improvement in nitrate reductase activity, the contents of total protein and carbohydrate also increased significantly at 15% fly ash. The proline content and the total antioxidant activity of beetroot increased significantly with increasing fly ash levels. The elevated levels of proline and antioxidant activity might be responsible for scavenging the oxidative stress caused by the higher concentration of fly ash in the soil. The principal component analysis presented significant correlations among the various considered parameters. Two principal components explained a total of 97.12% overall data variability in plants treated with different levels of fly ash. Therefore, this work suggests that the application of fly ash as a soil amendment is suitable to improve the growth and yield of beetroot.

“…Banyak riset yang telah dilakukan untuk pemanfaatan coal fly ash ini, seperti pemanfaatannya sebagai aditif pada concrete dalam bidang konstruksi (Ghazali, et al, 2019), sebagai adsorben untuk penyerapan zat toxin piridin dari limbah (Sofia et.al, 2020), pemanfaatannya dalam bidang pertanian seperti menjadi media tanam dan aditif pada pupuk (Dahiya, et al, 2018), serta pemanfataannya dalam bidang lingkungan seperti menjadi media tanaman penyerap bahan berbahaya pada lahan pertanian yang terkontaminasi (Kisku, et.al., 2018). Masing-masing pemanfaatan silika tersebut dari tahun ke tahun juga akan memberikan informasi mengenai metode pemisahan silikanya.…”

Penggunaan batubara sebagai sumber energi masih belum tergantikan hingga saat ini, sehingga kajian mengenai pemanfaatan abu batubara masih sangat perlu untuk dikembangkan. Abu batubara merupakan limbah hasil proses pembakaran batu bara yang komposisinya akan berbeda sesuai dengan jenis batubara yang digunakan dan proses pembakaran yang dilakukan. Salah satu komposisi penyusun utama dari abu batubara ini adalah silika. Silika memiliki potensi untuk dimanfaatkan dalam berbagai tujuan seperti untuk pengolahan limbah, untuk bahan aditif dalam pertanian, hingga sebagai nanosilika. Paper ini berisi informasi mengenai pemanfaatan silika dari abu batubara yang sudah ada serta metode yang efektif untuk mendapatkan silika dari limbah abu batu bara ini. Dari pembahasan diketahui bahwa studi pemanfaatan silika saat ini umumnya berfokus ke arah sintesis zeolite. Penelitian pemanfaatan silika sebagai nanosilika baru mulai dikembangkan baru-baru ini. Sementara itu, pemanfaatan silika tidak terlepas dari metode ekstraksi silika dari coal fly ash tersebut. Dari pembahasan diketahui NaOH masih menjadi pilihan utama dalam proses leaching silika. Studi ini diharapkan dapat memberikan informasi bagi kemajuan riset dalam rangkapengolahan dan pemanfaatan limbah. The use of coal as an energy source has not been replaced until now, subsequently the studies on the utilization of coal fly ash still need to be developed. Coal fly ash is waste from the coal combustion process whose composition will differ according to the type of coal used and the combustion process carried out. One of the main constituents of coal ash is silica. Silica has the potential to be used in various purposes such as for waste treatment, for additives in agriculture, to nanosilica. This paper contains information on the utilization of silica from existing coal fly ash and an effective method for obtaining silica from the coal fly ash. Based on the discussion, it is known that the current study of the use of silica generally focuses on the synthesis of zeolite. The research on the use of silica as nanosilica has only recently been developed. Meanwhile, the role of silica is related to the method of extracting silica from the coal fly ash. It is known that NaOH is the main leaching solution in the case of silica leaching process. This study is expected to provide information for research progress in the context of processing and utilizing waste.

“…The main purpose of reusing coal fly ash as solid waste material is to minimize the environmental which can occur from its disposal. Some of its utilization has already been explored are the utilization of coal fly ash in concrete to enhance its durability, as fly ash bricks, for road and embankments works, in mine backfilling, as an adsorbent, and additive in agriculture (Ahmaruzzaman, 2010;Basu et al, 2009;Dahiya & Budania, 2018;Gorai, 2018;Wardani, 2008).…”

The residue of thermal power plants is known as coal fly ash and has been considered solid waste pollution worldwide. The characteristic of coal fly ashes showed that it contains several components that could be utilized in several fields. One of the potential utilization is in the agricultural application. This study analyzed the characteristic of two different types of coal fly ashes and their effect on the soil. The x-ray fluorescence (XRF) analysis resulted that SiO2, Al2O3, Fe2O3, CaO dan MgO are the five major components in the soil, and both coal fly ash, CFA A and CFA B. This XRF analysis result concluded that coal fly ashes have great potential to be a substitute for silica fertilizer. Then, the effect of the coal fly ash addition also was studied by the moisture content and nutrient (N, P, and K) content characteristics in the soil and the soil-ash mixture. The findings indicated that the addition of 125 grams of coal fly ash A had a greater impact on the soil compared to fly ash B when 250 grams of soil was used.
