SU Aggies faculty, students present research at int’l conference in Japan
Silliman University (SU) College of Agriculture faculty and students presented research at the 11th International Exchange and Innovation Conference on Engineering & Sciences (IEICES 2025), held on October 30–31 at Kyushu University in Fukuoka City, Japan.
Among the presenters were Asst. Prof. Arsenio D. Bulfa, Zeus Rayjan T. Cabus, Emilio B. Jacinto II, Jack C. Silva, Cherk Andrew P. Ignacio, Reiki Elijah L. Varquez, and John Glen Amistoso.
The annual conference gathered leading academics, researchers, and students to discuss cutting-edge developments in materials, energy, and environmental engineering and sciences, creating a dynamic international platform for collaboration and knowledge exchange.
Bulfa delivered two oral presentations. The first, “Biomass Waste Applications on Carbon Dioxide (CO₂) Emission Rates in Clay Loam Soil,” co-authored with Teodora A. Cubelo and Jose Edwin C. Cubelo, explored the potential of biomass waste in mitigating CO₂ emissions from soil, offering insights for climate-smart agricultural practices and soil carbon dynamics. The second presentation, “Multi-criteria Decision Analysis (MCDA) and GIS-assisted Suitability Evaluation for Corn Production in Negros Oriental, Philippines,” co-authored with Marcial S. Buladaco II and Eureka Teresa M. Ocampo, demonstrated a spatial and analytical approach to identifying optimal areas for corn cultivation, supporting strategic land-use planning and improved agricultural productivity.
The poster presentations likewise showcased strong research outputs from the student delegates. “Effects of Ultrasonic Treatment on Germination, Seedling Growth, and Root-to-Shoot Ratio in Guava Seeds,” by Silva, Cabus, Rehel A. Diaz, Jose Edwin C. Cubelo, and Bulfa, presented evidence on how ultrasonic technology can enhance germination and early seedling development in guava. Meanwhile, “Enhancing Germination, Growth, and Vigor of Upland Kangkong Seeds through Ultrasonic Treatment,” by Jacinto, Owen Lloyd A. Dumago, Varquez, Diaz, Cubelo, and Bulfa, highlighted the promising role of ultrasonic treatment in improving germination, vigor, and seedling growth in upland kangkong.
All submitted papers underwent rigorous evaluation by external reviewers and subject-matter experts prior to presentation. Accepted works will be included in the official conference proceedings indexed in Scopus, the Kyushu University Institutional Repository (QIR), and Google Scholar.
