Abstract

This study aims to examine the utilization of High-Density Polyethylene (HDPE) plastic waste as a partial substitute for fine aggregate in the manufacture of Cellular Lightweight Concrete (CLC) lightweight bricks. The method used is a laboratory experiment with variations in the addition of HDPE of 0%, 5%, 10%, and 15% to the CLC mixture. Each variation was tested to determine the compressive strength, dry unit weight, and water absorption capacity after curing for 28 days. The results showed that the addition of HDPE affected the mechanical characteristics of lightweight bricks. The compressive strength decreased with increasing HDPE percentage, where the highest value was recorded at the 0% HDPE variation of 1.16 MPa and the lowest at the 15% variation of 0.92 MPa, below the SNI 8640-2018 standard. The highest dry unit weight was achieved at a composition of 5% HDPE of 3.32 kg/m³, indicating optimal density. However, the addition of HDPE also increased water absorption, with the highest average of 25.08% at the 15% variation. Thus, the use of HDPE waste as a substitute material shows environmentally friendly potential, but needs to be optimized so as not to reduce the structural quality of CLC lightweight bricks.

Abstract

Concrete is a material used in modern construction and is a very important component in the manufacture of structures. Concrete has advantages, but also disadvantages, namely low tensile strength. To increase the tensile strength of concrete, fibers are added to the mix. One of the efforts made to increase the tensile strength of concrete is the addition of fibers to the fiber-concrete mixture. The purpose of this study is to examine the compressive strength and tensile strength values in fiber concrete if added with variations in fiber addition. An innovation in increasing the value of mechanical quantities in concrete is the use of bent wire fibers as a mixture in fiber concrete. This material is taken from former pieces in construction projects to connect steel reinforcement with Sengkang reinforcement and is also widely found in building shops. The fibers were also analyzed for microstructure using SEM (Scanning Electron Microstructure) tools. The length of this bent wire fiber is 13 mm with a diameter of 0.82 mm and has a minimum tensile strength value of 334.5 MPa. The variations in the addition of these bent wire fibers are 0%, 3%, 6%, and 9% of the total weight of the steel fiber. The soaking life of concrete is 7 days, 14 days, and 28 days. The results of this study show that the more variations in the addition of bent wire fibers, the compressive strength value of concrete and the tensile strength value of concrete will also increase. It can be seen that fiber concrete with an immersion life of 28 days with a variation of 9% added bent wire fiber has a maximum compressive strength value of concrete which is 63,645 MPa and a maximum value of tensile strength of 3,294 MP.

Abstract

Concrete material is one of the most widely used construction materials in Indonesia due to its high compressive strength and adaptability to various construction needs. Despite its benefits, concrete has limitations, notably its weakness in tension and tendency to crack under tensile stress. This research focuses on High-Performance Concrete (HPC) with compressive strength exceeding 80 MPa, reinforced with 3D Dramix steel fibers to enhance both compressive and tensile strength. The study aimed to evaluate the compressive strength and splitting tensile strength of HPC mixed with varying percentages (0%, 3%, 6%, and 9%) of Dramix 3D steel fibers. Additionally, the methodology involved microstructure analysis using Scanning Electron Microscopy (SEM) and mechanical testing on HPC samples cured at 7, 14, and 28 days. Results indicate that the compressive strength reached a maximum of 94.776 MPa, and tensile strength reached 6.599 MPa with a 9% fiber addition at 28 days, highlighting the material's potential application in high-performance structural elements. The findings suggest that 3D Dramix steel fibers significantly enhance the mechanical properties of HPC, making it a viable option for durable construction.

Abstract

The Medan City Government plans to make infrastructure changes by building underpass at the existing signalized intersection between Road Ir. H. Juanda and Road Brigjend. Katamso to reduce traffic congestion. In recent years, vehicle emissions have become a global concern due to their significant impact on public health and environmental quality. As road traffic and vehicle numbers continue to grow, transportation has become a key contributor to air pollution from vehicle exhaust emissions. Consequently, it is essential to assess whether the infrastructure changes from signalized intersection to underpass have an impact on vehicle exhaust emissions. The impact analysis of infrastructure changes on vehicle exhaust emissions is evaluated through traffic simulation using PTV Vissim software with two scenarios, namely the do nothing scenario (existing signalized intersection) and the do something scenario (underpass) ), focusing on CO, NOx, and VOC emissions. The comparative results indicate substantial changes: CO emissions declined by 42.5% (from 40,991 grams to 23,567 grams), VOC by 37.1% (from 9,500 grams to 5,975 grams), while NOx emissions increased by 23.3% (from 7,075 grams to 8,725 grams). These findings suggest that the infrastructure changes from signalized intersection to underpass can positively influence air quality by reducing specific pollutants. However, further studies are necessary to examine its broader impact on other types of vehicle exhaust emissions using diverse emission categories, multiple calculation approaches, and various analytical methods for comprehensive comparison.

Abstract

Penelitian ini bertujuan untuk menganalisis pengaruh penggunaan abu cangkang sawit (ACS) sebagai bahan pengganti 15% semen dan penambahan serat baja 2% terhadap sifat mekanis beton mutu tinggi (High Strength Concrete/HSC). Pengujian meliputi uji beton segar (slump flow, T50 time, V-funnel, L-box) dan beton keras (kuat tekan, kuat tarik belah, kuat lentur). Hasil menunjukkan seluruh parameter beton segar memenuhi standar EFNARC untuk Self-Compacting Concrete (SCC). Kuat tekan meningkat signifikan dari 30,89 MPa (beton normal) menjadi 90,25 MPa (HSC)—peningkatan 192% atau 65,7% lebih tinggi dari target mutu. Kuat tarik belah meningkat dari 2,95 MPa menjadi 5,63 MPa (90,8%), sedangkan kuat lentur meningkat dari 6,27 MPa menjadi 16,69 MPa (166%) pada balok komposit dengan lapisan HSC 5 cm. Peningkatan ini disebabkan oleh reaksi pozzolanik abu cangkang sawit yang menghasilkan kalsium silikat hidrat (C-S-H) tambahan dan kontribusi serat baja dalam menahan propagasi retak serta meningkatkan daktilitas. Analisis displacement menunjukkan peningkatan ketebalan lapisan HSC meningkatkan kekakuan lentur dan menurunkan lendutan maksimum. Kombinasi ACS 15% dan serat baja 2% terbukti efektif meningkatkan performa mekanis dan struktural beton hingga tiga kali lipat dibanding beton normal, sekaligus mendukung material ramah lingkungan dalam teknologi beton modern dengan memanfaatkan limbah industri kelapa sawit.

Abstract

Penelitian ini menganalisis sinergi beton berkekuatan tinggi (High Strength Concrete/HSC) dan beton normal dengan penambahan abu sekam padi (ASP) sebagai pozzolan dan serat bambu sebagai penguat terhadap peningkatan kuat lentur balok komposit. Abu sekam padi dengan kandungan silika tinggi (90–95%) menggantikan sebagian semen untuk meningkatkan kekuatan dan durabilitas, sedangkan serat bambu meningkatkan ketangguhan dan ketahanan retak. Metode eksperimental dilakukan di Laboratorium Rekayasa dan Bahan Beton, Fakultas Teknik Universitas Sumatera Utara dengan variasi lapisan HSC setebal 1 cm, 3 cm, dan 5 cm pada bagian atas balok beton normal. Pengujian dilakukan terhadap beton segar (slump flow, T50, V-funnel, L-box) dan beton keras pada umur 28 hari (kuat tekan, kuat tarik, kuat lentur). Hasil menunjukkan penambahan 10% abu sekam padi dan 1% serat bambu meningkatkan kuat tekan dan lentur secara signifikan. Kuat lentur tertinggi diperoleh pada balok dengan lapisan HSC 3 cm, menunjukkan peningkatan kapasitas beban dan penurunan lendutan. Analisis metode momen-area dan SAP 2000 memperkuat hasil laboratorium dengan selisih lendutan dalam batas toleransi. Kombinasi HSC, abu sekam padi, dan serat bambu memberikan efek sinergis terhadap peningkatan performa mekanis beton dan mendukung pengembangan material konstruksi berkelanjutan.

Abstract

Medan City is one of the metropolitan cities with a high level of congestion and population density, resulting in traffic jams, delays, as well as air and noise pollution. This study aims to analyze the performance of intersections on S.M Raja – Halat road, Brigjend Katamso – Mesjid Raya road, and Brigjend Katamso - Pelangi road before and after the operation of the underpass at the Ir.H.Juanda – Brigjend Katamso road intersection using vissim software. Data were obtained from traffic surveys such as vehicle volume surveys, road geometry, traffic signal cycle times, and vehicle speeds. The data obtained from the vissim software simulation results include queue lengths, delays, and level of service at the intersection. For the simulation results at the Ir.H.Juanda – Brigjend Katamso road intersection before the operation of the underpass, the average queue length was 274.3 m and the average delay was 307.38 sec/vehicle, with an average level of service of F (very poor). After the operation of the underpass, the average queue length was 8.38 m and the average delay was 0.96 sec/vehicle, with an average level of service of A (excellent). With a 5-year scenario, the average queue length was 38.53 m and the average delay was 12.34 sec/vehicle, with an average level of service of B (good). Thus, a significant difference is clearly visible between before and after the operation of the underpass, such as the results of queue lengths, delays, and service levels, which have caused new conflicts at the intersections closest to the underpass.
