Indonesian University Students Create Cold Lava Floods Warning System

"The tool's interconnection will make it quickly disseminate early warning of cold lava floods. It also makes it easier for the public to monitor weather conditions, as well asrivers vulnerable to cold lava floods."

This tool is equipped with solar panels as its main power source, making it also energy efficient and environmentally friendly.

"The tool has two sides," Rohsan explained. "One side acts as a client to retrieve data, while the other is the server to convey information from processed data.

"The client side will be installed at several points along the river to ensure the ebb and flow of the river around the volcano by utilizing steel slings connected to the rotary encoder," Rohsan explained.

"If ground shifts occur, the rotary encoder will automatically rotate and detect soil displacement with accuracy of up to 1cm."

He added that the buoy mechanical sensor could detect water level changes. "If a landslide is detected and the height is above the specified threshold, it will trigger the client side to send a message via the GSM module to the server side."

The server will collaborate data from the client with weather forecast data from the Meteorology, Climatology and Geophysics Agency (BMKG) which can be accessed to the public.

"The client side of the tool will take data to be sent to the server once every minute, such as weather status, rainfall, and current information on river water levels," Rohsan asserted.

Then, the server will send it to the storage and processing database. The public can access these via Android-based applications and websites. Indonesia sits on Indo-Pacific Ring of Fire, making the country vulnerable to volcanoes, earthquakes and other natural disasters.
