(2018-2020) Embedded Electronics System for Buoy Tsunami Early Warning Systems

From 2018 to 2020, I worked on the embedded electronics system for a buoy-based Tsunami Early Warning System in Indonesia. The project focused on building and integrating the electronics needed for offshore monitoring, including sensor interfaces, power management, communication modules, and the internal wiring of the buoy payload.

My work involved preparing the electronics enclosure, connecting and testing the internal modules, and supporting field deployment activities at sea. The system was designed to collect ocean monitoring data from the buoy and transmit it reliably as part of an early-warning infrastructure.

The electronics were assembled inside a protected buoy structure to withstand marine conditions. The internal system combined power distribution, communication electronics, embedded control hardware, and cable routing for the sensors and external interfaces.

This project gave me hands-on experience with embedded systems in a real marine deployment environment, where reliability, maintainability, waterproofing, and field testing were just as important as the circuit and firmware design.
