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

Excess water capacity in river areas will cause flood hazards that mostly occur in downstream areas that are flood areas at high risk as a result of natural processes and the effects of human actions. In the case of floods, water runoff undermines the embankments and drowns agricultural / settlement areas upstream, and is aggravated by considerable sedimentation. Based on the existing problems, the analysis of the discharge and the water level (water profile) becomes very important to get a precise picture of locations prone to the overflow of the river Kr. This pase. Discharge and water profile analysis using HEC RAS software for various return periods. From the results of the research is expected to get a clear picture of the location that is vulnerable to overflow so that in handling the river will be on target. Based on the calculation using HEC RAS software, at point P 581 the water level condition at 2.3 years discharge the difference of the height of the embankment and the water level is 50 cm to 60 cm, while in the discharge condition 25 years the elevation of the face almost passes through the dike's height with a selisish of about 10 -15 cm. This condition is an unsafe category because for rivers whose debit is greater than 15 m3/s the minimum wavelength is 1.00 m. So that with good conditions at 2.3 years discharge and 25 years of discharge is very potential to occur overflow.Keywords: discharge, waterlevel, flood

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.

Abstract

AbstractExpansive clay soils possess high shrink-swell potential, which often leads to structural failures when used as subgrade material. This study aims to evaluate the effectiveness of a combination of lime (KP) and fly ash treatment (FA) in improving the mechanical and physical properties of expansive clay soil obtained from Quarry Cot Kayee Adang, Lhokseumawe City. The research methods included soil classification (AASHTO), physical properties tests, consolidation, compaction (standard Proctor), Atterberg limits, and direct shear tests with additive variations of 0%, 5%, 9%, and 12% lime, along with 5% fly ash. The results showed that the original soil was classified as A-7-6 (36) according to the AASHTO system, with a plasticity index (PI) of 33.80% and a maximum dry density (γdmax) of 1.28 gr/cm³. Adding 9% lime increased the γdmax to 1.32 gr/cm³, and when combined with 5% fly ash, reduced the PI to 22.06%. The direct shear test indicated an increase in cohesion from 0.571 kg/cm² to 0.748 kg/cm² and internal friction angle from 10.7° to 18.1°, resulting in an increase in shear strength (τ) from 7.439 kg/cm² to 12.365 kg/cm². Stabilization using a combination of 9% lime and 5% fly ash proved to be the most effective in enhancing compaction, shear strength, and volumetric stability. These findings recommend the use of this mixture as an efficient alternative for improving expansive clay soil in civil infrastructure construction. Keywords:Expansive clay; fly ash; lime; shear strength; soil stabilization AbstrakTanah lempung ekspansif memiliki potensi kembang susut tinggi yang menyebabkan kerusakan pada konstruksi, terutama jika digunakan sebagai tanah dasar. Penelitian ini bertujuan untuk mengevaluasi efektivitas kombinasi kapur (KP) dan fly ash treatment (FA) dalam memperbaiki sifat mekanik dan fisis tanah lempung ekspansif yang berasal dari Quarry Cot Kayee Adang, Kota Lhokseumawe. Metode penelitian meliputi serangkaian uji laboratorium yang mencakup: uji klasifikasi tanah (AASHTO), uji sifat fisis (kadar air alami, berat volume dan berat jenis), uji batas atterberg, uji konsolidasi,uji  pemadatan (standar Proctor), dan uji kuat geser langsung (Direct Shear Test) dengan variasi campuran 0%, 5%, 9%, dan 12% kapur serta 5% fly ash. Hasil pengujian menunjukkan bahwa tanah asli tergolong A-7-6 (36) berdasarkan sistem AASHTO, dengan nilai indeks plastisitas (PI) sebesar 33,80% dan berat volume kering maksimum (γdmak) sebesar 1,28 gr/cm³. Penambahan 9% kapur meningkatkan γdmak menjadi 1,32 gr/cm³ dan menurunkan PI menjadi 22,06% ketika dikombinasikan dengan 5% fly ash. Uji kuat geser menunjukkan peningkatan kohesi dari 0,571 kg/cm² menjadi 0,748 kg/cm² dan sudut geser dalam dari 10,7° menjadi 18,1°, yang berkontribusi terhadap peningkatan kuat geser maksimum (τ) dari 7,439 kg/cm² menjadi 12,365 kg/cm². Stabilisasi menggunakan kombinasi 9% kapur dan 5% fly ash terbukti paling efektif dalam meningkatkan kepadatan, kekuatan geser, dan stabilitas volumetrik tanah. Temuan ini merekomendasikan penggunaan bahan tersebut sebagai alternatif yang efisien untuk memperbaiki tanah lempung ekspansif dalam pekerjaan konstruksi infrastruktur. Keywords:Fly ash; kapur; kuat geser; stabilisasi tanah; tanah lempung ekspansif
