SPATIAL DISTRIBUTION OF BRACKISHWATER POND SOIL CHARACTERISTICS IN PEKALONGAN CITY CENTRAL JAVA PROVINCE
ABSTRACT: Spatial distribution
of brackishwater pond soil has a vital role in the system of bioenvironment
including brackishwater pond environment. This research was aimed to determine
the spatial distribution of brackishwater pond soil characteristics inPekalongan
City, Central Java Province. A total of 59 sampling points each with twodifferent
soil depth samplings were determined by simple random method. A total of 21
soil characteristics were measured in the field and analyzed further in thelaboratory.
Geostatistic with Kriging Interpolation method in the ArcGIS 9.3 software were
used to depict the distribution of the data across the landscape. Furthermore, the
spatial distribution was presented by using ALOS AVNIR-2 image. Research resultindicates
that in general, pond soil in Pekalongan City can be classified as soil withhigh
variability or relatively heterogenic with the value of variation coefficient
morethan 36%. Soil characteristics which have similar pattern of spatial distribution
are acid sulfate soil and soil nutrient content. High value of pH, organic
matter, and totalN of soil, and on the other hand, low value of PO4 were
generally found in the pond area of Krapyak Lor Village, while in Pekalongan
City, it was found high clayish soilcontent but relatively homogenous. It is
recommended that pond management mustbe based on soil characteristics which are
different from one area to another. Thesoil characteristics itself can be drawn
and assessed through spatial distribution.
