Graduating BS Geodetic Engineering students John Dave C. Maclang and Alexi Mae Y. Narca earned 1st Runner-Up honors at the Engineering Innovations Congress (ICON) 2025, organized by the UP Engineering Student Council.

Their project, LALLY: Low-cost Autonomous Logger for Land Stability, introduces an affordable GNSS-based ground deformation monitoring system that enables real-time tracking of land subsidence in vulnerable areas. Built around a Raspberry Pi 5 and a u-blox ZED-F9P GNSS receiver, LALLY supports remote, high-precision data acquisition for a variety of land monitoring applications.

With a system cost of under ₱50,000, LALLY offers a budget-friendly alternative to conventional deformation monitoring solutions, which typically cost more than ₱1.2 million. This innovation holds potential for disaster risk reduction, early warning systems, and long-term development planning.

Maclang and Narca were coached by Assoc. Prof. Rosalie B. Reyes and Asst. Prof. Luis Carlos S. Mabaquiao. Their recognition at ICON 2025 highlights the strength of UP DGE’s undergraduate research and its commitment to real-world impact.
