Abstract

Increasing global energy demand, rapid electrification, and growing environmental concerns have intensified the need for energy-efficient technologies capable of supporting sustainable development. Power electronics plays a crucial role in modern electrical engineering by enabling efficient energy conversion, transmission, and utilization across renewable energy systems, electric vehicles, smart grids, and industrial applications. Persistent challenges related to switching losses, thermal dissipation, and converter inefficiencies continue to limit overall system performance and sustainability outcomes. This study aims to examine design strategies that enhance energy efficiency in power electronic systems and to evaluate their contribution to sustainable electrical engineering. A qualitative literature-based research design employing a systematic review approach was adopted. Relevant peer-reviewed publications published between 2015 and 2025 were analyzed to identify emerging technological trends, efficiency-enhancing mechanisms, and sustainability-oriented design principles. Findings indicate that advanced semiconductor technologies, particularly silicon carbide (SiC) and gallium nitride (GaN), significantly reduce power losses and improve conversion efficiency. Optimized converter topologies, intelligent control algorithms, and advanced thermal management systems further enhance system reliability and operational performance. Integrated implementation of these strategies produces greater efficiency gains than isolated technological improvements. The study concludes that sustainable electrical engineering requires a holistic design framework that combines technological innovation, system optimization, and environmental considerations. Such an approach can accelerate the development of highly efficient, reliable, and environmentally responsible electrical energy systems.

Abstract

Architectural engineering in the digital era is increasingly shaped by parametric design methodologies that enable complex form generation and performance-driven optimization. Rapid advancements in computational tools have transformed design processes, yet a persistent gap remains between architectural exploration and structural rationalization, often resulting in inefficiencies and post-design adjustments. This study aims to develop an integrated computational framework that aligns parametric design with structural performance, ensuring that architectural forms are both innovative and structurally feasible. A computational design-based methodology was employed, combining parametric modeling, finite element analysis, and algorithmic optimization across representative architectural typologies. Iterative workflows were implemented to establish continuous feedback between geometric parameters and structural responses. Results indicate that integrated parametric-structural models achieve higher structural efficiency, reduced material consumption, and improved deformation control compared to conventional and non-integrated approaches. Statistical analysis confirms significant performance improvements, while case-based validation demonstrates strong alignment between simulated and expected structural behavior. Findings further reveal that real-time integration enhances design adaptability and decision-making efficiency. This study concludes that the integration of parametric design and structural rationalization represents a robust and scalable paradigm for contemporary architectural engineering, offering significant implications for sustainability, performance optimization, and interdisciplinary collaboration.

Abstract

The rise of antimicrobial resistance is a global health crisis, demanding the urgent discovery of novel antibiotics. Indonesian mangrove forests, as a unique and underexplored ecosystem, represent a promising frontier for bioprospecting novel microorganisms. The plant rhizosphere, a zone of intense microbial activity, is particularly rich in actinobacteria, a phylum renowned for its prolific production of bioactive secondary metabolites. This research aimed to isolate and characterize novel antibiotic-producing actinobacteria from the rhizosphere of Indonesian mangrove plants. Rhizosphere soil samples were collected, and actinobacteria were isolated using selective media. All isolates were screened for antimicrobial activity against Staphylococcus aureus, Escherichia coli, and Candida albicans via the agar well diffusion method. The most potent isolate was subsequently characterized using morphological, biochemical, and 16S rRNA gene sequencing. From 72 distinct isolates, 15 displayed antimicrobial activity. One isolate, designated MGR-17, demonstrated exceptionally potent, broad-spectrum inhibition against all tested pathogens. Based on polyphasic taxonomy, MGR-17 was identified as a potentially novel species of the genus Streptomyces. In conclusion, the rhizosphere of Indonesian mangroves is a fertile source for discovering unique actinobacteria capable of producing novel antibiotics, and the discovery of Streptomyces sp. MGR-17 underscores this potential.
