A
n important option to reduce the risk of hydrometeorological disaster in Cisarua, Nyalindung village, West Java is by
applying hydrometeorology detection and early warning instrumentations. This area is threatened by landslides and debris
flow flash floods while agricultural drought may occur in the dry season. Debris flow flash flood flows right into the village
during the disaster of 2013 but the relocation of the affected residents is not an acceptable option. Early detection and warning
instrumentations is designed to fit with the hazard conditions and setting of the disaster-threatened areas. Instrumentation
is designed to be simple and cheap but reliable. This instrumentation uses a wireless sensor network system consisting of one
coordinator, one router and three end devices with radio wave telecommunication and equipped with sensors. Coordinator
serves as a monitoring and data center while router as intermediary data transmission from end device to coordinator, as well as
monitoring the weather conditions and give warning through the siren. End device serves as a detector of landslide and debris
flow flash flood hazards as well as agricultural drought hazards. To detect landslides, slope inclination sensors is used and placed
on the first end device on a potentially landslide prone area. The ground vibration sensor is placed at the second end device on
the river’s edge in the upstream to detect the flow of debris flows flash floods. To monitor agricultural drought, soil moisture
sensor is placed on the third end device on the agricultural land. Weather conditions are monitored by rainfall, temperature and
humidity sensors, wind speed and direction sensors as well as air pressure sensor which are mounted on the router and placed
on the location of residence at risk.
