Abstract

This study evaluates the effect of integrating coconut coir fiber at contents of 2 percent, 2.5 percent, and 3 percent, along with 5 percent silica fume, on the splitting tensile strength performance of concrete. The experimental results show that the 2 percent coconut coir fiber proportion provided the optimal performance, with a tensile strength value reaching 3.12 MPa, or an increase of 12.5 percent compared to the control concrete, which had a tensile strength of 2.5 MPa. Although fiber additions at higher contents of 2.5 percent and 3 percent still contributed to mechanical strength, a significant decline in concrete mixture workability was observed. The synergy between silica fume through its pore-filling effect and natural fibers proved effective in optimizing concrete density and ductility. This study concludes that the combination of these two materials can produce innovative concrete that is stronger and more environmentally friendly as a future construction material solution.

Abstract

Abstrak Kegiatan pengabdian masyarakat ini difokuskan pada penyediaan bantuan desain infrastruktur sanitasi tepat guna untuk menangani limbah domestik di Kelurahan Gandus, Kota Palembang. Urgensi perancangan ini didasari oleh kondisi geografis wilayah yang berada di kawasan bantaran sungai, di mana limbah domestik yang tidak terkelola berisiko tinggi mencemari badan air secara langsung dan merusak ekosistem perairan sungai. Perancangan Instalasi Pengolahan Air Limbah (IPAL) Komunal ini menjadi solusi strategis dalam meminimalisir pencemaran lingkungan pada pemukiman padat penduduk tersebut. Sistem ini dirancang untuk melayani kebutuhan sanitasi bagi 67 (KK) dengan kapasitas volume efektif reaktor sebesar 27.200 liter (27,2 m3 /IPAL) guna memastikan air buangan memenuhi baku mutu sebelum dialirkan. Desain teknis yang diterapkan mengadopsi sistem pengolahan biologis anaerobik yang mengintegrasikan empat kompartemen utama yaitu bak pengendapan dengan sistem Anaerobic Baffled Reactor (ABR) pada tahap awal, diikuti dengan dua tahap biofilter menggunakan media bioball dan media batu pecah untuk mengoptimalkan degradasi polutan organik. Struktur unit pengolahan ini memiliki dimensi total panjang 900 cm, lebar 200 cm, dan tinggi 200 cm. Berdasarkan pertimbangan kemudahan operasional dan efisiensi pemeliharaan bagi warga setempat, air hasil pengolahan akhir diarahkan untuk langsung dialirkan menuju sistem drainase lingkungan atau badan air terdekat. Diharapkan implementasi rancangan ini dapat memberikan kontribusi signifikan terhadap pelestarian ekosistem sungai serta peningkatan derajat kesehatan masyarakat di wilayah Kelurahan Gandus. Kata kunci: IPAL komunal; sistem anaerobik; sanitasi bantaran sungai; kelurahan gandus. Abstract This community service initiative focuses on providing design assistance for appropriate sanitation infrastructure to manage domestic wastewater in Gandus Village, Palembang City. The urgency of this design stems from the area’s geographical location along a riverbank, where unmanaged domestic wastewater poses a high risk of directly polluting water bodies and damaging the river’s aquatic ecosystem. The design of this Community Wastewater Treatment Plant (WWTP) serves as a strategic solution to minimize environmental pollution in this densely populated residential area. This system is designed to meet the sanitation needs of 67 households (HH) with an effective reactor volume capacity of 27,200 liters (27.2 m³ / WWTP) to ensure that effluent meets quality standards before discharge. The technical design employs an anaerobic biological treatment system integrating four main compartments: a sedimentation tank with an Anaerobic Baffled Reactor (ABR) in the initial stage, followed by two biofilter stages using bioball media and crushed stone media to optimize the degradation of organic pollutants. The treatment unit structure has total dimensions of 900 cm in length, 200 cm in width, and 200 cm in height. Considering operational ease and maintenance efficiency for local residents, the treated effluent is directed to be discharged directly into the local drainage system or the nearest water body. It is hoped that the implementation of this design will make a significant contribution to the preservation of the river ecosystem and the improvement of public health in the Gandus neighborhood. Keywords: community wastewater treatment plant; anaerobic system; riverbank sanitation; gandus subdistrict.

Rekomendasi desain yang dihasilkan diharapkan dapat menjadi acuan dalam pengembangan sistem drainase di kawasan Perumahan Bukit Sejahtera. Kata kunci: drainase; perumahan; redesain saluran; EPA SWMM. Abstract Drainage issues in urban residential areas are caused by standing water due to insufficient capacity of the drainage system to handle the volume of rainwater runoff. This condition occurs in the Bukit Sejahtera Housing Estate in RW 04, Karang Jaya, Palembang, where there is sedimentation, blockage of the drainage system due to domestic waste, and damage to the drainage system's construction. The goal of this PkM is to provide recommendations for redesigning the drainage system to improve its performance and reduce the potential for flooding. The project was carried out by five faculty members and six students from the Indo Global Mandiri University, in collaboration with the Karang Jaya District Office and the RW 04 community representatives. The implementation method of the activity includes the preparation stage, field survey, data collection, analysis of the drainage conditions using EPA SWMM, design recommendations, and socialization and delivery of the activity results. Based on the EPA SWMM simulation results, optimization was performed on four priority channels, consisting of two primary and two secondary channels. The results of the simulation after optimization show an increase in flow capacity, so the drainage network can safely handle the planned flow rate. The socialization activity received positive feedback from the community, as evidenced by the participants' enthusiasm in sharing drainage issues in their environment. The design recommendations produced are expected to serve as a reference for the development of the drainage system in the Bukit Sejahtera housing complex. Keywords: drainage; housing; redesigning channels; EPA SWMM.

Abstract

Beton biasanya digunakan sebagai bahan struktural utama dalam konstruksi bangunan. Alasannya adalah karena beton memiliki beberapa keunggulan, seperti bahan baku yang mudah didapat, biaya yang relatif murah, mudah dibentuk sesuai kebutuhan, dan perawatan yang minimal. Beton membutuhkan bahan tambahan alami dan buatan untuk meningkatkan kualitas getasnya. Beton serat, bahan aditif masih dapat digunakan. Beton Serat dapat memberikan daktilitas, kekuatan tarik dan lentur yang lebih tinggi, ketahanan terhadap beban fatik dan beban kejut, serta mengurangi retak susut, di antara manfaat lainnya. Beton polimer juga banyak memberi keuntungan dibandingkan beton konvensional, termasuk kekuatan tinggi stabilitas pemadatan yang unggul, tahan terhadap zat kimia, korosi dan kedap air. Tujuan penelitian ini adalah untuk menganalisis pengaruh penambahan serat kawat bendrat dan epoxy resin terhadap karakteristik beton. Variasi yang digunakan serat kawat bendrat yaitu 2%, 2,5%, 3% sebagai bahan tambah, sedangkan epoxy resin 4% sebagai subtitusi semen. Hasil pengujian kuat tarik belah beton dapat disimpulkan bahwa nilai optimum dari campuran epoxy 4% dan kawat bendrat 3% sebesar 3,45 MPa. Penambahan serat kawat bendrat dapat meningkatkan nilai kuat tarik belah beton, dan epoxy resin memiliki daya perekat yang cukup kuat terhadap kuat tarik belah beton.

Abstract

The construction of the village boundary monument is a form of community service that aims to provide clarity on the administrative boundaries of an area and strengthen village identity. This activity was carried out by lecturers and students of Indo Global Mandiri University in Ujan Mas Village, Jangkar Mas Village, Pagar Alam City, South Sumatra Province, considering that this village does not have a clear boundary marker. The method of implementing this activity consists of several stages, namely location surveys, designing designs using AutoCAD, preparing a Budget Plan (RAB) with Microsoft Excel, making 3D designs using SketchUp and building monuments according to agreed designs. The survey was conducted to determine the strategic location in accordance with the administrative boundaries of the village, while the design was made by considering the aesthetic aspects and character of the village. The preparation of the RAB aims to manage cost needs effectively, so that development can run according to the available budget, the Budget Plan needed for the construction of the village boundary monument is IDR 9,526,500. The result of this activity is a village boundary monument that not only functions as an area marker, but also as a symbol of village identity that strengthens cultural values and clarifies administrative boundaries. The existence of this monument is expected to support more organized regional management and provide long-term benefits for the Ujan Mas Village community.

Abstract

The use of porous concrete is a crucial strategy for mitigating surface water runoff in urban areas. However, low compressive strength often poses a major challenge in its application. This study aims to analyze the effect of adding silica fume on the mechanical and hydraulic properties of porous concrete. The research was conducted experimentally in a laboratory setting, following ACI 522R-10 standards for mix proportions and ASTM C39 for compressive strength testing. The silica fume content was varied at 0%, 3%, 5%, and 7% of the total cement weight, with a total of 24 test specimens, each a 10x20 cm cylinder. Test procedures included a slump test for workability, a permeability test, and a 28-day compressive strength test. The results showed that increasing the silica fume content significantly reduced the slump to 0 cm at a 7% increase, indicating that the mixture became stiffer. As the micro-structural density increased, the permeability coefficient decreased from 0.0288 cm/s to 0.0082 cm/s. Although drainage capacity decreased, the compressive strength of the concrete increased significantly by 69.6%, from 6.58 MPa to 11.16 MPa at the 7% content. The novelty of this study lies in identifying the optimal silica fume content to achieve a structural compressive strength above 10 MPa while preserving drainage functionality. These findings confirm that silica fume effectively enhances the mechanical performance and durability of porous concrete, making it highly suitable for use in eco-friendly infrastructure, such as parking lots and neighborhood roads, that require a balance between structural strength and water infiltration efficiency.©The author(s).
