Abstract

Flowing concrete, in accordance with ASTM C 1017 is defined as concrete with a slump flow value greater than 19 cm. However, the use of flowing concrete also presents several challenges, particularly in terms of workability and the need for environmentally friendly materials. Various studies have been conducted on the use of substitute or additive materials in concrete mixtures. This study focuses on flowing concrete mixed with Petung bamboo fibers (Dendrocalamus Asper) to determine the effect of varying bamboo fiber percentages on the slump flow value. The study utilizes Petung bamboo fibers as an additive material. The bamboo fibers, cut into lengths of 5 cm and evenly distributed, were mixed into the flowing concrete. The fiber content variations used were 0%, 3%, 3.5%, 4%, and 4.5%, with a superplasticizer (SP) dosage of 1.5% of the cement weight. The slump flow test results indicate that the higher the percentage of bamboo fiber added, the lower the slump flow value.

Abstract

Surabaya is an earthquake-prone area due to its location on an active fault zone, namely the Kendeng Fault Zone. Hospitals play a crucial role during disasters; therefore, a strong structure is required to withstand various loads, including seismic loads. This study aims to compare the structural behavior of a hospital building using shear walls and a base isolation system with Lead Rubber Bearings (LRB). The comparison was carried out through modeling of both the existing structure and the modified structure using ETABS v.22 software. The results show that the structure with base isolation has smaller inter-story drifts and P-Delta effects, especially on the upper floors. The base isolation system is also more effective in damping seismic forces, maintaining structural stability, and enhancing building safety. Based on the analysis, the LRB base isolation system proves to deliver better structural performance compared to the shear wall system in resisting earthquake loads.

Abstract

Beton merupakan material konstruksi yang banyak digunakan karena memiliki kenggulan seperti kuat tekan tinggi, kemampuan mengikuti bentuk cetakan, tahan air dan api, serta biaya perawatan yang relatif murah dengan umur pakai panjang.Produksi beton dalam skala besar memberikan tekanan pada ketersediaan bahan baku alam, khususnya agregat halus (pasir) yang penggunaannya terus meningkat seiring pembangunan. Pemanfaatan material lokal dan limbah industri sebagai substitusi agregat halus menjadi alternatif penting untuk mengurangi ketergantungan pada sumber daya alam yang tidak terbarukan. Salah satu material lokal potensial adalah serbuk batu kapur dari Kabupaten Bangkalan, Madura, yang selama ini belum dimanfaatkan secara optimal dan cenderung menjadi limbah. Serbuk batu kapur mengandung senyawa SiO2, Al2O3, alkali, besi, juga kandungan Ca(OH)2 yang dapat meningkatkan sifat betonterutama mengurangi penyerapan air beton dan memperbaiki struktur mikro beton. Penelitian ini bertujuan mengkaji pengaruh substitusi serbuk batu kapur sebagai pengganti sebagian agregat halus terhadap nilai resapan beton. Metode campuran beton mengacu pada SNI 02-2834-2000. Terdapat lima presentase campuran yaitu 0%, 10%, 20%, 30%, 45%.Menggunakan benda uji berbentuk silinder ukuran 10cm x 20cm dengan total sample sebanyak 10 buah. Berdasarkan hasil pengujian, penambahan serbuk batu kapur pada kadar 0%, 10%, dan 20% meningkatkan nilai resapan beton,sementara pada kadar 30% dan 45% nilai resapan menurun karena serbuk batu kapur mulai mengisi pori-pori kecil dalam beton, sehingga membuat beton menjadi lebih rapat dan sulit di tembus air.Penggunaan serbuk batu kapur yang berlebihan dapat mengganggu proses hidrasi dan menurunkan kualitas beton. Oleh harena itu, pemanfaatan serbuk batu kapur perlu dioptialkan agar dapat meninngkatkan kualitas beton tanpa mengurangi kemampuan kedap airnya.

Abstract

Cement, as one of the ingredients in making mortar, has a significant impact on the environment. As an alternative to the use of cement, carbide waste can be used as a substitute for cement. Carbide waste is a by-product of the welding industry in the form of a grayish solid. One of the contents of carbide waste is CaO, CaO itself is one of the contents of cement. The CaO element has potential in making mortar and can increase compressive strength. This study aims to analyze the impact of adding carbide waste as a partial substitute for cement to the mortar mixture. In this study, the percentage of carbide waste addition as a cement substitute was 0%, 2.5%, 5%, 7.5%, and 10%. This study aims to determine the optimum percentage of the mortar mixture with the addition of carbide waste. The research method used includes laboratory testing of the mortar mixture with varying levels of carbide waste to analyze the compressive strength. The results of this study concluded that the most optimum mortar compressive strength is at a percentage of 7.5% with a compressive strength of 29,430 MPa. However, at a percentage above 7.5% the compressive strength of the mortar decreased.

Abstract

The increasing use of concrete in the construction world encourages massive exploitation of the environment that has limestone or karst reserves to be used as the main raw material for making cement, to reduce the excessive use of cement, a way is used to utilize fly ash as a substitute for part of the cement in the concrete mixture to reduce the negative impact of limestone mining activities as well as cement production which contributes a total of 9% of CO2 emissions on earth. In this study, bendrat wire will also be added to determine the workability of fresh concrete mixes. From the results of the study it was found that concrete with fly ash substitution without bendingt wire mixture got an average height of 10.7 cm, while the variation with the addition of bending wire at 3% decreased in the average slump value to 10 cm where the increasing percentage of bending wire made the average slump value go down, seen in the 6% and 9% variations which experienced a decrease in the average height of the slump with a height of 9.7 cm and 9 cm, this can have an impact on the workability of the concrete mix itself, with a higher percentage of bending wire will have difficulty when applying to building construction.

Abstract

Cement is one of the main materials in mortar that has a negative impact due to its manufacture. Various new studies and innovations continue to be carried out to increase the utility value of waste and reduce the negative impacts of cement manufacture. One of the innovations is the use of rice husk ash as a substitute for cement in making mortar. It is known that rice husk ash has a high silica content where the content is the same as the content of cement. The duration of good burning of rice husk ash is 6 hours with normal burning. The percentage of rice husk ash used in the study was 0%, 5%, 10%, and 15% of the weight of cement. The test results showed that 10% rice husk ash with a burning duration of 6 hours used as a mortar mixture had the highest compressive strength value of 32.04 MPa.

Abstract

Indonesia memiliki populasi sebesar 286,6 juta jiwa, menjadikannya negara terpadat ke-4 di dunia, yang menciptakan tantangan dalam memenuhi kebutuhan ruang, terutama di kawasan perkotaan. Salah satu solusi untuk mengatasi masalah ini adalah pembangunan gedung bertingkat guna menyediakan hunian atau akomodasi, namun struktur tersebut memerlukan perhatian khusus terhadap pengaruh beban gempa untuk memastikan kestabilan dan keamanan bangunan. Metode seperti pushover analysis sering digunakan untuk menganalisis kinerja struktur terhadap beban lateral atau gempa. Selain itu, pemodelan menggunakan perangkat lunak seperti Autodesk Revit memungkinkan perhitungan volume material yang lebih akurat, sehingga biaya konstruksi dapat direncanakan secara efisien. Efisiensi biaya menjadi salah satu faktor utama yang harus diperhatikan, selain aspek ketahanan gempa. Penelitian ini bertujuan membandingkan level kinerja struktur serta biaya antara Sistem Rangka Pemikul Momen Khusus (SRPMK) 12 lantai dan struktur dengan dinding geser (Sistem Ganda) 12 lantai. Berdasarkan analisis pushover, kedua sistem menunjukkan kinerja pada kategori Immediate Occupancy (IO), namun hasil perbandingan harga dan volume material menunjukkan bahwa Sistem Rangka Pemikul Momen Khusus (SRPMK) memiliki biaya yang lebih tinggi sebesar 25,43% dibandingkan Sistem Ganda.

Abstract

Banda Aceh is located in a region with high seismic activity due to the interaction between the Indo-Australian and Eurasian plates, making high-rise buildings in this area require a reliable earthquake-resistant structural design. This study aims to analyze and compare the dynamic behavior of reinforced concrete structures using Lead Rubber Bearing (LRB) and Friction Pendulum System (FPS) base isolation systems against the conventional fixed-base system. The modeling was carried out on a 10-story apartment building using ETABS v.17, referring to SNI 1726:2019, SNI 1727:2020, and SNI 2847:2019 standards. The analysis results show that the base isolation systems reduce inter-story drift by up to 77% for FPS and 49% for LRB compared to the fixed-base model, but increase the total structural displacement with maximum values reaching 2254% for LRB and 1889% for FPS due to isolator movement. Furthermore, the base shear force increased approximately 3.16 times for LRB and 3.40 times for FPS compared to the fixed-base system. The use of isolation also significantly extends the structural vibration period, with the largest increase in the first mode reaching 77% for LRB and 67% for FPS. Overall, the implementation of base isolation effectively enhances structural flexibility and seismic response while reducing potential structural and non-structural damage in earthquake-prone regions.
