Abstract

Global sustainability is a big challenge for various industry sectors, including the construction industry. Concrete is a key material in infrastructure development due to its high strength and good durability. However, concrete production has significant environmental impacts, such as the exploitation of natural resources and increased carbon emissions. Therefore, there is a need to innovate materials that are more environmentally friendly without reducing the quality of concrete. This research aims to explore the use of Styrofoam waste and yarn as additives in concrete mixes. Styrofoam was chosen due to its lightweight and biodegradable nature, its use in concrete can reduce environmental pollution. Meanwhile, yarn was added to increase the strength of concrete that had undergone changes due to the addition of Styrofoam. This research was conducted using an experimental method with the addition of 30% Styrofoam from the total fine aggregate as a fixed variable. In addition, variations of yarn were used at 0.5% and 1% of the total concrete mix. Tests were carried out using cylindrical test objects with a diameter of 15 cm and a height of 30 cm, with a total of 8 samples tested to determine the compressive strength value of the resulting concrete. The test results showed that the highest compressive strength was obtained in the variation of adding 1% yarn, with a value of 15.03 MPa. This shows that the combination of styrofoam and yarn still allows the concrete to have sufficient strength for certain construction applications. From this research, it can be concluded that the use of Styrofoam and yarn in concrete has the potential to be an environmentally friendly material innovation that supports the sustainability of the construction industry. By utilizing this waste, it is expected to reduce environmental impact and open up new opportunities in the development of sustainable construction materials

Abstract

Prioritizing school building maintenance solely based on structural damage often leads to inefficient budget allocation and fewer beneficiaries. The research introduced an integrated Cost-User Effectiveness Ratio (CUER) to establish maintenance priorities by combining three critical factors: damage severity, maintenance costs, and the number of affected students. The CUER formulation employed the Geometric Mean or the root mean multiplication of the cost effectiveness and user effectiveness ratio to balance these factors systematically. The methodology encompassed several steps, including damage assessment and calculation of component importance weights using the Analytical Hierarchy Process (AHP), to determine integrated damage levels, costs, and student weights. These inputs were subsequently used to generate priority rankings of schools requiring maintenance. As a result, the case study in Wonogiri Regency illustrates the superiority of the proposed method over the conventional method. While the conventional approach prioritizes 27 schools benefiting 2,442 students, the CUER approach prioritizes 33 schools benefiting 2,957 students, demonstrating increased efficiency and broader impact. The CUER-based model presents a systematic and equitable solution to prioritize school building maintenance, ensuring the optimal allocation of resources and maximizing benefits within existing budgetary constraints. This innovative approach addresses current challenges in maintenance planning and offers significant implications for improving the management of educational infrastructure.

Abstract

Flooding has become an increasingly critical global challenge, with urban areas experiencing more frequent and severe flood events due to climate change and rapid urbanization. This research evaluates the capacity of flood pumps in Madiun City, Indonesia, to address waterlogging issues in urban drainage catchment areas. The objective of this study is to assess the adequacy of existing pump systems using hydrological analysis and determine the required pump capacity improvements for effective flood control. This research employed a quantitative descriptive method, utilizing primary data from field measurements and secondary data from relevant agencies. The study area encompasses eight pump houses in Madiun City with varying pump capacities. Hydrological analysis was conducted using rainfall data from 2011 to 2021, applying the Nakayasu Synthetic Unit Hydrograph method and Pearson III Log distribution for design rainfall calculation. Results indicate that existing drainage channels can accommodate flood discharge for return periods up to 25 years but require normalization for 50-, 100-, and 1000-year return periods. The Cassowary pump house analysis showed that the current pump capacity of 3 m³/s with a 4.23 m head is adequate for the 10-year return period. The research demonstrates that pump system effectiveness is crucial for flood control in low-lying urban areas. This study contributes to flood management literature by providing a systematic evaluation framework for urban pump systems and offers practical recommendations for municipal infrastructure planning.

Abstract

Beton adalah salah satu material yang sering dijumpai pada struktur konstruksi. Hal ini menjadikan beton harus memiliki ketahanan terhadap kondisi lingkungan sekitar, baik dalam kondisi kering maupun basah. Tak sedikit di lingkungan sekitar terdapat bahan agresif seperti sulfat yang dapat menurunkan durabilitas dan sifat mekanis beton. Dalam rangka mengatasi permasalahan tersebut peneliti menggunakan bahan tambah silica fume untuk meningkatkan ketahanan pada beton terhadap serangan sulfat. Dalam penelitian ini, rancangan campuran beton dibuat menurut metode ACI dengan kuat tekan rencana 25 MPa. Pengujian ketahanan beton terhadap serangan sulfat dilakukan dengan perendaman benda uji siklus kering-basah pada larutan Natrium Sulfate (Na2SO4) dengan konsentrasi 5% dengan variasi penambahan silica fume 0%, 8%, dan 10%. Benda uji berupa silinder beton berdiameter 15 cm dan tinggi 30 cm untuk menguji kuat tekan beton dan kehilangan berat setelah direndam dalam larutan sulfat. Sedangkan untuk pengujian perubahan panjang menggunakan benda uji balok mortar dimensi 285 mm x 25 mm x 25 mm. Hasil pengujian didapatkan kadar optimum penambahan silica fume sebesar 8% pada beton dengan perendaman larutan sulfat yang berkontribusi meningkatkan nilai kuat tekan beton sebesar 44,91% dan mengurangi efek ekspansi pada mortar hingga 53,39%, sedangkan kadar 10% mengurangi kehilangan berat hingga 0,15% dibandingkan beton tanpa bahan tambah silica fume.
