Abstract

Limbah fly ash dari Pembangkit Listrik Tenaga Uap (PLTU) Lontar, Serang, Banten, merupakan sisa pembakaran batu bara yang berpotensi mencemari lingkungan jika tidak dikelola dengan baik. Kegiatan pengabdian kepada masyarakat ini bertujuan untuk memanfaatkan limbah tersebut melalui pelatihan pembuatan paving block bagi warga Desa Lontar. Metode yang digunakan dalam pelatihan meliputi pemberian teori dan praktik langsung mengenai persiapan bahan baku, pencampuran material, teknik pencetakan, serta pengeringan paving block. Pelatihan juga menekankan pentingnya keselamatan kerja dan pengelolaan lingkungan selama proses produksi. Hasil dari kegiatan ini menunjukkan peningkatan keterampilan warga dalam memanfaatkan fly ash menjadi paving block yang bernilai ekonomis. Beberapa peserta berencana mengembangkan produksi ini secara mandiri, baik untuk memenuhi kebutuhan desa maupun untuk dijual ke pasar yang lebih luas. Kegiatan ini diharapkan dapat meningkatkan kesejahteraan ekonomi masyarakat sekaligus mengurangi dampak negatif limbah industri terhadap lingkungan.

Abstract

Road construction planning must consider the characteristics and strength of the soil. This study aims to determine the classification of soil and the effect of fly ash-based geopolymer as an added material on the specific gravity of soil. Specific gravity testing was carried out using a pycnometer to obtain the specific gravity of the soil. The test object used is a soil sample added with geopolymer with fly ash as raw material and an alkaline activator (Na2SiO3and NaOH). The NaOH concentration is 10 M with a solution ratio of 2.0 (Na2SiO3 to NaOH), fly ash content of 20%, and variations in S / L (fly ash to activator) levels of 1/2 and 1/2.5. Based on the research that has been done, the results show that the soil used in the study is included in the organic clay soil with a specific gravity value of 2.49. The effect of fly ash-based geopolymer in this study increases the specific gravity value, with a specific gravity of 2.60 for variation B (80% soil, 20% FA, S/L 1/2) so that the soil falls into the organic clay category and 2.69 for variation C (80% soil, 20% FA, S/L 1/2.5) so that the soil falls into the non-organic clay category.
