Numerical Analisys of Segmental Box Girder’s Stress with Eccentric Tendon Anchoring on Balanced Cantilever Box Girder Bridg
Kevin Raenaldo, Muhammad Sigit Darmawan, Nur Ahmad Husin Abstract Diagonal crack damage on the web of balanced cantilever box girder bridges has frequently occurred worldwide, including in Indonesia. Previous studies have shown that these cracks can result from additional shear stress caused by prestressed tendon anchoring. In this study, an analysis was conducted using […]
Effect of Flow Rate NaOH on CO₂ Absorption Efficiency Using a Column Tray Absorber
Rizal Arifin, Nurul Faizah, Ardista Izdhihar Kaloka, Anisa Fatma Aulia, Gladys Sukma Thufailah, Muhammad Adnan Syukur Abstract CO₂ in industrial gas streams reduces process efficiency, corrodes equipment, and affects product quality. Additionally, CO₂ emissions contribute to climate change and global warming. To mitigate these effects, CO₂ removal through absorption is essential. Absorption involves contacting […]
Compressive Strength Performance of High-Volume Fly Ash Concrete with CaCO3 Addition
Yosi Noviari Wibowo, Tatas Tatas, Yuyun Tajunnisa, Amalia Firdaus Mawardi, Miftaqul Zanah Abstract This study investigates the compressive strength performance of High-Volume Fly Ash (HVFA) concrete with added CaCO₃ as a sustainable alternative to Ordinary Portland Cement (OPC) for infrastructure applications. The experimental research replaces a significant portion of cement with fly ash—a byproduct […]
The Effect of Build Orientation on Liquid Absorption and Wear of 3D-Printed Denture Materials
Muhammad Ikhlas, Sukmaji Indro Cahyono, Benediktus Tulung Prayoga, Rini Dharmastiti, Budi Arifvianto, Muslim Mahardika Abstract Up till now, denture has been widely used for resolving dental problems, especially those due to attrition. The attrition of tooth enamel could lead to wear and lowering the functions of normal teeth. So far, denture is made conventionally […]
