Abstract:
Based on the observation towards climate station in several agriculture production centers,
there is an increase temperature. Temperature rise due to greenhouse effect is very clearly
visible, e.g., in Banjarbaru Indonesian Agency of Meteorological, Climatology, and
Geophysics (BMKG), misal di stasiun BMKG Banjarbaru, Banjarmasin Sei Tabuk Special
Farm Meteorology Station (SMPK), and South Kalimantan Kotabaru BMKG. This
temperature rise impacted to plant’s respiration increase that led to the reduction of
photosynthesis result. Adaptation strategy with plants water balance analysis to determine
the correct planting time and surplus period and water deficit, in various growth phases, is
one of water permanent strategic measures to know water suffiency in the field. Material
used in this research is TRMM from 3B43 type in the form of grid with monthly temporal
resolution and spatial resolution 0.25° x 0.25° with data from 1998 – 2015 period. Data format
in the form of binary from ftp://disc2.nascom.nasa.gov/data/TRMM/Gridded/3B43_V7.
Reanalysis surface temperature data is grid data from European Centre for Medium-Range
Weather Forecasts (ECMWF) from 1998 -2015 period in netcdf format. Water balance
analysis used Thornthwaite and Mather (1957) method. Water balance analysis shown
groundwater in sufficient category (>60%) happens during November – July period,
meanwhile water surplus happens during December – June period. Whereas during August
– October period is in less period (<40%). This information can be used in the formulation of
one season planting pattern both in wet or dry field.
