| Abstrak/Abstract |
Kelud is a volcano in Indonesia located between the Kediri and Blitar
districts of East Java province. This volcano has erupted multiple times between
the year 1000 and 2014, resulting in over 200,000 casualties. Therefore, a volcano
warning system is needed to detect forthcoming eruptions to minimize the number
of casualties. A warning system was developed based on sensor nodes comprising
vibration, temperature and gas (sulfur and carbon dioxide) sensors to monitor
physical parameters of the volcano, drone surveillance, mapping and temperature
measurement, and a mobile robot carrying the same sensors as the sensor nodes
for both normal and emergency situations. The system was tested on the Kelud
volcano in normal condition in August 2019. The system detected 1 Hz of
seismicity, under 1 ppm of sulfur and carbon dioxide, lake temperature at 23 °C to 55.3 °C, ground temperature at 32 °C, and air temperature between 23 °C and 25
°C. The system can be used for 37 hours at full operation with 1 charging cycle of
the solar cell and is suitable for application in a dangerous environment.
