Abstract:
Drought is an act of nature most powerful on the availability of the water supply, both
necessary for the benefit of agricultural and to human need.There are three phases of
analysis to research the severity of this drought: (1) To identify station rainfall in the study
areas. Monthly data precipitation using rain observation data ( 2005-2014) from 2 stations in
Indrapuri and Jantho; (2) Analysis was conducted rainfall to get the drought meteorology of
each station precipitation with the gauge standardized precipitation index ( SPI ); and (3)
Analysis was conducted spline interpolate method index value dryness of each rainfall station
to get scatter drought.The analysis by using the 3 monthly scale SPI method (SPI-3), The
rainfall in 2005-2014 year had not a very dry because rainfall for 12 months from January
until December for that 10 years, only on June-July-August (JJA) experienced dry conditions
with the drought index averange among -0,80 until -1,00. The rest months September-
October-November (SON), Desember-January-February (DJF) and March-April-May
(MAM) in normal condition, with the -0,99-0,99 value range of the SPI.The hidrologis
disaster mitigation may be done by structural (optimalize the development of the Krueng
Jreue dam, rehabilitation and irrigation maintenance. Storage excess water in the rainy
season for use in the dry season), and non structural (non structural to predict drought,
reforestation, planting plant water saving, the use of mulch and organic matter)
