An elementary school dropout from Klampok district in Banjarnegara, Central Java, has created a detection device to warn people of landslides.
Sudarsono, 45, who volunteers at the disaster mitigation agency (BPBD) of the regency that has suffered multiple landslides, built the device with a budget of less than Rp 5 million. He called it Elwasi after the Javanese words eling (remember), waspada (cautious) and siaga (prepared).
"I created the device out of concern that many areas have suffered from disasters but have yet to install early-warning systems," he said recently while presenting the device during a coordination meeting of Central Java's BPBD in Semarang.
National Disaster Mitigation Agency (BNPB) head Lt. Gen. Doni Manardo and Central Java Governor Ganjar Pranowo praised the invention.
