“BLUE” to detect Red Tide

April 14, 2025

Led by Leslie Guadalupe, Jewelle Rafa, and Trinity Bautista, Senior High School students from Dr. Yanga’s Colleges in Bocaue, Bulacan, have developed an innovative device called Project B.L.U.E. or Breaking Limits for Underwater Exploration capable of detecting the presence of red tide in rivers. This innovative technology not only highlights the students’ skill in robotics and environmental science but also addresses a critical issue affecting aquatic ecosystems and public health in the Philippines and even globally.

Red tide, caused by harmful algal blooms, poses significant risks to marine life and local communities—leading to fish kills, shellfish poisoning, and economic harm to fisheries and tourism. The newly invented detection device aims to provide an early warning system, allowing authorities and local residents to respond promptly to prevent health hazards and protect the ecosystem.

Under the guidance of experienced robotics coach, Ms. Anne Rax and with access to advanced resources, the students utilized various sensors and programming tools to create a unit that can analyze water samples in real-time. The device is designed to identify the specific types of algae associated with red tide events, providing accurate and timely data that can be shared with environmental agencies and local governments.

Dr. Yanga’s Colleges is well-regarded for its commitment to fostering innovation in the robotics field. The development of this device reflects the institution’s dedication to equipping students with practical skills while encouraging them to tackle pressing global challenges.

The team hopes that their innovation will engage other students and communities in discussions about environmental stewardship and the vital role of technology in preserving our natural resources. In a world facing increasing ecological changes, the ingenuity of Dr. Yanga’s students shine a bright light on the future of sustainable development in the Philippines and beyond.
