Abstract
Limbah (waste material) memiliki urgensi yang besar untuk diolah kembali dan didaur ulang. Sejumlah besar limbah seperti fly ash dan bottom ash menimbulkan kekhawatiran karena merupakan residu pembakaran batubara yang dapat mencemari lingkungan. Limbah Spent Bleaching Earth (SBE) juga memiliki dampak negatif terhadap lingkungan. SBE adalah residu yang dihasilkan dari proses pemutihan minyak kelapa sawit atau minyak nabati. Dengan mengelola limbah dengan efektif, kita dapat mengurangi dampak lingkungan negatif, mengoptimalkan penggunaan sumber daya alam yang terbatas, mengurangi biaya operasional, dan mendorong inovasi dalam industri konstruksi.Penelitian ini memanfaatkan limbah (waste material) seperti fly ash, bottom ash dan Spent Bleaching Earth (SBE) sebagai campuran dalam pembuatan bata ringan. Pembuatan bata ringan ini menggunakan konsep Non-Autoclaved Aerated Concrete (NAAC). Tahapan penelitian produk dilakukan dari persiapan bahan penyusun dilanjutkan dengan perencanaan mix design dengan dilakukan uji trial densitas dan kuat tekan pada umur 3. Tahap pembuatan benda uji dimulai dari pengecoran pada kubus 50×50×50 mm dan balok 285×25×25 mm disertai dengan pengujian mortar segar. Tahap terakhir adalah pengujian mortar keras yang terdiri dari pengujian densitas, kuat tekan, porositas, penyerapan air, mikrostruktur dan penyusutan. Hasil dari penelitian menunjukkan bahwa material fly ash menghasilkan hasil kuat tekan yang lebih tinggi diantara ketiga limbah yang digunakan, namun dengan konsekuensi densitas yang dihasilkan juga meningkat lebih besar. Mengacu pada SNI 8640-2018, disimpulkan bahwa penggunaan limbah fly ash dan bottom ash memenuhi syarat sebagai bata struktural, sedangkan SBE hanya memenuhi syarat bata non-struktural. Bata dengan material SBE lebih unggul dalam segi penyerapan air dan tingkat penyusutan yang rendah.

Waste materials have great urgency to be reprocessed and recycled. Large amounts of waste such as fly ash and bottom ash are a cause for concern as they are coal combustion residues that can pollute the environment. Spent Bleaching Earth (SBE) waste also has a negative impact on the environment. SBE is the residue generated from the bleaching process of palm oil or vegetable oil. By managing waste effectively, we can reduce negative environmental impacts, optimize the use of limited natural resources, reduce operational costs, and encourage innovation in the construction industry. This research utilizes waste materials such as fly ash, bottom ash and Spent Bleaching Earth (SBE) as a mixture in making lightweight bricks. The manufacture of these lightweight bricks uses the concept of Non-Autoclaved Aerated Concrete (NAAC). The stages of product research are carried out from the preparation of constituent materials followed by mix design planning with trial tests of density and compressive strength at age 3. The stage of making test objects starts from casting on 50×50×50 mm cubes and 285×25×25 mm beams accompanied by fresh mortar testing. The last stage is hard mortar testing which consists of testing density, compressive strength, porosity, water absorption, microstructure and shrinkage. The results of the study showed that fly ash material produced higher compressive strength results among the three wastes used, but with the consequence that the resulting density also increased more. Referring to SNI 8640-2018, it is concluded that the use of fly ash and bottom ash waste qualifies as structural bricks, while SBE only qualifies as non-structural bricks. Brick with SBE material is superior in terms of water absorption and low shrinkage rate.
