Wireless Sensor Network for Landslide Monitoring in Nusa Tenggara Timur
Abstract: Landslides in many
regions constitute serious hazards that cause substantial life and financial
losses. To overcome and reduce the damages, efforts to monitor landslides are
developed. One such technology utilizes a wireless sensor network (WSN).
Results obtained from studies conducted in the Ikanfoti village, Kupang
District, Nusa Tenggara Timur (NTT) Province (S 10o16’ 21.9” and E
123o40’59.8”) as pilot project, give result that the application of WSN can be
applied properly. We detect and measure vibrations caused by landslides by
vibration sensor (accelerometer) on Micaz devices. The results of this study
indicate that changes in accelerometer values ranging from 0.2 g (gravity) to
0.49 g of either the X or Y of accelerometer indicate that soil begins to move
but not significantly. Value above 0.5 g is a value that indicating a
significant change of ground motion. The value of 1 g and above of ground
motion indicates a very strong activity and should be alarmed. It is expected
that this research provides the foundation for the application of WSN in
various areas in NTT Province and Indonesia in general, for establishing
thorough and reliable early warning system (EWS).
