Abstract

This research explores the impact of road construction projects on the environment and society, aiming to provide a comprehensive analysis of both the direct and indirect consequences of infrastructure development. Through a detailed review of historical trends, case studies, and comparative analyses, the study highlights the significant environmental and social impacts associated with road construction. Key environmental concerns include habitat destruction, increased pollution, and noise pollution, while social impacts encompass displacement, changes in property values, and community disruption. The research reveals that while road construction projects can offer substantial benefits, such as improved connectivity and economic growth, they also pose challenges that need to be addressed. Advances in technology and methodology have enhanced our understanding of these impacts, leading to more effective mitigation strategies and better planning practices. However, the study identifies gaps in the implementation and effectiveness of Environmental and Social Impact Assessments (EIAs and SIAs) and emphasizes the need for rigorous monitoring and adaptive management. This research contributes valuable insights for policymakers, planners, and developers, guiding the creation of infrastructure that supports long-term sustainability and enhances quality of life.

Abstract

North Sumatra has several universities in various regions spread across 33 regencies/cities, where the number of students studying at several universities in North Sumatra according to the higher education database (PDDIKTI) is 130,182 students. As many as 25 percent of the number of students at several universities in North Sumatra who understand the use of information systems at the universities where they study, affect students' readiness to understand information system learning, which reduces students' understanding and knowledge, as well as their competence in knowing the contents of the material, understanding learning objectives, and understanding information system applications for decision making. This study aims to determine and analyze the extent to which the digital-based information system learning process influences students' readiness to understand learning using information systems in the digital era. The research method uses a quantitative descriptive method with a sampling technique using the accidental sampling method, and data collection techniques are carried out using observation, distributing questionnaires and documentation studies. The results of the study describe that the process of learning digital-based information systems has an effect on students' readiness in understanding learning information systems in the digital era, where students must be able to improve their knowledge, understanding and skills sufficiently by reading books and other literature, as well as increasing their applied knowledge about information systems in the digital era in order to be able and ready to improve their understanding of learning information systems.

Abstract

This research investigates the impact of integrating neodymium magnets into synchronous generators on energy efficiency and performance. Neodymium magnets, known for their high magnetic flux density, strong coercivity, and excellent thermal stability, offer potential enhancements over traditional ferrite magnets. Through a combination of experimental studies, computational simulations, and analytical evaluations, this study demonstrates that synchronous generators equipped with neodymium magnets achieve an 8-12% increase in energy efficiency and a 10-15% increase in power output. The superior magnetic properties of neodymium magnets facilitate more effective energy conversion and reduce operational losses, ensuring consistent performance even under challenging conditions. However, the adoption of neodymium magnets faces several challenges, including high initial costs, environmental impacts from rare-earth element extraction, technical design adaptations, and supply chain vulnerabilities. Despite these hurdles, the significant performance benefits of neodymium magnets present a compelling case for their integration into synchronous generators, promising more efficient, reliable, and sustainable power generation systems.

Abstract

This research investigates the conversion of ilmenite (FeTiO₃) to titanium dioxide (TiO₂) in the ternary system TiO₂-Fe₂O₃-Na₂O, focusing on improving TiO₂ yield, purity, and quality for industrial applications. The study explores the effect of sodium oxide (Na₂O) as a flux to facilitate the removal of iron oxide (Fe₂O₃) impurities, which often degrade TiO₂'s optical and chemical properties. Through a series of experiments varying Na₂O concentrations and temperatures (900-1200°C), the research demonstrates that Na₂O enhances TiO₂ formation by promoting phase transitions and accelerating the separation of iron from titanium. Optimal conditions (5% Na₂O at 1100-1200°C) resulted in high-purity TiO₂ (up to 99%) with yields reaching 95%, while reducing iron oxide contamination. This study provides valuable insights into the reaction mechanisms and optimal parameters for producing high-quality TiO₂, with significant implications for its use in pigments, coatings, and advanced materials where purity and performance are critical. The findings contribute to more efficient, scalable methods for TiO₂ production from ilmenite, benefiting industries dependent on this essential material.

Abstract

This research investigates the performance of Self-Compacting Concrete (SCC) in earthquake-resistant buildings, comparing its behavior with conventional concrete under seismic conditions. SCC, known for its high flowability and ability to self-compact without the need for mechanical vibration, offers several advantages in construction, including reduced labor costs, faster construction timelines, and enhanced durability. The study explores the mechanical properties of SCC, such as compressive strength, shear strength, and flexural performance, and evaluates its resistance to cracking, permeability, and environmental degradation factors critical for earthquake resilience. Through experimental analysis and case studies, the research highlights SCC's superior performance in terms of structural integrity and long-term durability, particularly in regions prone to seismic activity. The findings demonstrate that SCC not only accelerates the construction process but also improves the overall safety and longevity of earthquake-resistant structures, making it a promising material for modern, sustainable construction practices. This study concludes that SCC offers significant benefits over conventional concrete, providing a cost-effective, durable, and environmentally friendly solution for earthquake-resistant building design and construction.
