Abstract

Abstract — Industrial waste products can be considered as renewable resources, one of them is a steel manufacturing, which produced dust waste contain sponge iron, scrap metal and other steel wastes that impacted to environment. This waste material was called Electric Arc Furnace Dust (EAFD). This study investigates the feasibility of using EAFD as a cement replacement compared to silica fume (SF) and fly ash (FA) in terms of Chemical composition, workability, setting time, compressive strength and rapid chloride permeability resistance. The results showed that workability of EAFD is almost similar to control even if percentage of EAFD was increased. It is not refer to FA more workable or SF less workable with increase percentage of replacement. Furthermore, the EAFD significantly affect the setting time, which 3% EAFD replacement bring to prolong final setting time to more than 24 hours, while the setting time of SF and FA did not significant affected along with the increase replacement percentage. In addition, the 3% EAFD is optimum replacement for compressive strength and it is equivalent replacement level to 5% SF and 15% FA. Finally, the EAFD enhance the resistance for rapid chloride permeability more than FA but less than SF.

Abstract

Youth dropping out of school in Mesjid Peunteut Village, Blang Mangat District, Lhokseumawe City as a partner village were still less productive and have an impact on low income levels. In fact, they have never received training from any party for entrepreneurial activities and have the expertise to create certain products, especially in the field of civil engineering. This training aimed to provide knowledge and skills to out-of-school youth in order to provide them with the expertise to make seamless texture paving block products that are easy to market so as to generate a steady income. The number of participants involved in the activity were 20 people, consisted of 8 women and 12 men with an age range of 20 - 25 years. Partners acquired theoretical knowledge, technical skills in making paving block texture seamless manual products, production management and product marketing. The offline method was used for theoretical debriefing activities combined with presentation techniques in class and hands-on practice in civil engineering workshops. The results of the training obtained an average value of theoretical understanding of 88.1 and technical understanding of 95. This showed partners have acquired theoretical and technical knowledge to plan mix compositions, manufacture products manually, arrange production and marketing costs. Thus, it becomes a job field for youth who drop out of school to get a steady income.

Abstract

Industrial waste containing silica (Si), alumina (Al), and calcium (Ca) has potential as an alternative binder in concrete. These compounds form C-S-H and C-A-H gels in water-based systems, or Si-O-Si, Si-O-Al, N-A-S-H, and C-A-S-H gels in alkali-based geopolymer systems, enhancing strength and influencing setting time. One example is investigate FA from Nagan Raya (FANR) Coal-Fired Power Plantation in Aceh. This study evaluates its performance in geopolymer mortar through chemical and mechanical analysis. FANR is rich in Si and Al, improving mortar strength, while Ca content affects binding time. XRD analysis revealed crystalline phases in FANR and geopolymer binders, resulting in low reactivity. SEM analysis showed spherical particles with foggy surfaces, differing from typical glassy fly ash, which influences workability and alkali absorption. Mortar tests indicated the best performance at 8M NaOH and a Na₂SiO₃/NaOH ratio of 3.0, achieving 18.30 MPa compressive strength at 28 days. Higher alkali concentrations increased viscosity, reducing workability and final strength. Overall, FANR shows promise as a geopolymer binder with proper optimization of activator ratios.

Abstract

Masjid Raudhatul Jannah yang berlokasi di Gampong Alue Awe, Kecamatan Muara Dua, Kota Lhokseumawe merupakan sarana ibadah yang digunakan secara aktif oleh masyarakat sehingga memerlukan kondisi bangunan yang aman dan nyaman. Permasalahan utama yang dihadapi mitra adalah terjadinya kebocoran pada plat dak atap akibat retakan yang memungkinkan air hujan meresap ke dalam struktur bangunan. Kondisi tersebut berpotensi menurunkan kenyamanan jamaah, mengganggu aktivitas ibadah, serta mempercepat kerusakan elemen bangunan apabila tidak segera ditangani. Kegiatan pengabdian kepada masyarakat ini bertujuan mengimplementasikan teknologi waterproofing coating berbasis geopolimer sebagai material waterproofing ramah lingkungan untuk mengatasi kebocoran atap. Metode pelaksanaan meliputi survei dan identifikasi kerusakan, persiapan permukaan beton, formulasi dan pelapisan waterproofing coating berbasis geopolimer pada area retak, serta monitoring dan evaluasi hasil pekerjaan. Hasil kegiatan menunjukkan bahwa waterproofing coating berbasis geopolimer mampu membentuk lapisan pelindung yang menutup retakan mikro dan mengurangi infiltrasi air pada permukaan beton. Setelah aplikasi dilakukan, tidak ditemukan lagi rembesan air pada area yang telah diperbaiki selama periode pengamatan awal. Selain meningkatkan kinerja waterproofing, penggunaan waterproofing coating berbasis geopolimer fly ash juga memberikan nilai tambah melalui pemanfaatan limbah industri sebagai material konstruksi berkelanjutan. Kegiatan ini menunjukkan bahwa waterproofing coating berbasis geopolimer dapat diterapkan secara efektif sebagai solusi penanganan kebocoran atap bangunan ibadah sekaligus mendukung penerapan material konstruksi yang ramah lingkungan.
