Mr Zulieta during the FIMFS Plenary sessions.

In 22-24 October 2024, Lex C Zulieta, a sophomore in the Bachelor of Science in Marine Biology program at Xavier Ateneo de Cagayan, represented the university during the 56th Federation of Institutions of Marine and Freshwater Sciences (FIMFS) Inc Annual Convention, in Mati City, Davao Oriental. The event, brought together marine and freshwater science experts, students, and professionals from across the country. Attendees discussed recent developments in the field, shared research, and forged new collaborations aimed at addressing challenges in aquatic sciences.

Zulieta presented his research titled “An Acoustic Comparison of the Sound Reduction Index (SRI) between Polyurethane (PUR)-based and Samo (Sargassum spp)-based Insulation Foams" in a parallel session focused on "Technological Advancement and Innovation in Marine-Freshwater Ecosystems through Aquaculture and Fisheries." His study explored the potential of alternative, eco-friendly materials for reducing underwater noise pollution, an increasing concern in marine and freshwater ecosystems worldwide.

To assess the effectiveness of these materials, Zulieta’s team conducted a series of acoustic tests to measure the Sound Reduction Index (SRI) of both foam types. The SRI is a key metric used to determine the sound-absorbing capabilities of materials in aquatic environments.

Zulieta’s research was made possible through the collaborative efforts of a dedicated team of researchers from the BS Marine Biology program at Xavier Ateneo, including: Mr Muhammad Nurul Ylham B Indol, Mr Zaldy S Ocon, Jr, Mr Michael Joshua D Mabulay, Mr Matthew L Padilla. The study was further supported by the guidance and mentorship of several faculty members from Xavier Ateneo: Dr Astrid L Sinco and Ms Julie Ann P Butron, MSc of the Department of Biology, and Ms Mary Grace C Francisco, MSc of the Department of Physics, and Ms Vanissa G Laurente, MA of the Department of English Language and Literature. Zulieta’s mentors provided crucial expertise, from experimental design to data analysis, ensuring the study met the highest academic standards.
