| Summary: | One of the primary hazards caused by the volcanic activities is pyroclastic
flow quickly moving and consisted of hot gas, volcanic dust, and stones. The flow
can move quickly along the slope of volcano with greatly high temperature. The
natural conditions of Merapi mount causes difficulty in monitoring pyroclastic
flow visually, while the use of seismic equipment requires experts to analyze data.
It makes difficulty among field personnel to give early warning to society in quick
and appropriate manner. Therefore, a study is conducted by designing the early
warming system of pyroclastic flow that can give facilities for field personnel to
monitor the pyroclastic flow and can give a hazard warning.
The study designs a geographic information system-based early warning
system of pyroclastic flow by using temperature censor as pyroclastic flow
detection equipment. It is expected that the system can give facilities in
monitoring and give early warning to population around Merapi mount, so it can
reduce victims resulted from the pyroclastic flow. The study was conducted using
a field survey method, observation, and interview, while the designing of software
was done by using a waterfall methodology or a linear sequential model
consisting of analysis, design, implementation, and testing. To test the system, an
infrared temperature censor was made using ATMega8535 microcontroller.
Result of the study indicates that the geographic information system-based
prototypical early warning system of volcano�s pyroclastic flow was built by
using a temperature censor as a pyroclastic flow detection equipmnent.
Temperature censor used in the testing of system was infrered temperature censor
by using microcontroler as the changer of analogue-to-digital signal. The system
has some facilities to regulate censor placement, read temperature in each censor,
and give a hazard warning in accordance with predetermined limitations. |
