This research attempts to compare the method of analysis
and the mapping of endemic outbreaks of brown
planthopper on the staples commodity and horticulture
using spatial autocorrelation method. The research was
done through three steps; those are (1) data preprocessing
(2) endemic prototype of BPH (3) the analysis of the
increase of attacked stem brown planthopper parameter, the
rainfall intensity, and the density of natural enemy. GISA,
LISA, and Getis Ord Statistic were used in the endemic of
BPH modeling. The result of this research shows that
hotspot pattern in 37 subdistrict area and coldspot pattern in
13 subdistrict areas in 2001 - 2010 can be classified by
using these methods. From the comparison of Local
Moran’s experiment map and Getis Ord BPH experiment
map in 2001, 2006 and 2010, it is found that the indication
of hotspot on Local Moran’s is the same as clustering
indication on Getis Ord based on the value of Z(Gi)>2. The
distribution of BPH attack is determined by the spatial
object connectivity pattern of BPH population, rainfall and
the territorial position.
