Greetings to the Readers of Jurnal Teknosains!

We are delighted to present the December edition of our journal (Volume 16, Number 1, December 2025), which showcases a rich collection of interdisciplinary research in biomedical engineering, environmental technology, renewable energy, materials science, and applied biological sciences. The studies featured in this issue reflect the dynamic landscape of technoscientific inquiry, highlighting both fundamental advancements and practical solutions to contemporary challenges.We open this edition with an in silico exploration of boswellic acid as a potential antibacterial agent against Cutibacterium acnes and other acne–associated pathogens. Through molecular docking targeting nine key bacterial proteins, the study demonstrates that boswellic acid exhibits strong binding affinity, particularly to the transcriptional regulator TcaR, suggesting its promise as a topical antibacterial candidate. This work underscores how computational biomedicine continues to accelerate the discovery of safer and more effective dermatological agents....To close this edition, we present a study on Constructed Wetlands (CW) using roof–tile fragments and Echinodorus palaefolius for treating phosphate–rich laundry wastewater. Remarkably, the system achieved a 99.96% reduction in phosphate levels, driven by adsorption, biodegradation, and microbial interactions—particularly from Proteus and Citrobacter species.Together, the articles in this issue reflect the dedication of researchers in advancing science and engineering for societal benefit. As we close this final issue of the year, we would also like to extend our warmest wishes to all our readers, authors, and reviewers. May this holiday season bring rest, reflection, and joyful moments with your loved ones. We look forward to welcoming you again in our June 2026 edition with new research contributions and advancements across the technoscience fields. Warm regards,Editor in ChiefJurnal Teknosains
