Food insecurity refers to the consequence of inadequate
consumption of nutritious food at region, society or
household, considering the physiological use of food by the
body as being within the domain of nutrition and health.
However, household with food insecure still found in almost
whole provinces with high proportion. So, it is necessary to do
a research to determine factors that influence food insecurity
in a province by calculating spatial effect of inter-regency
or municipality. In this research, food insecurity that will
be analyzed is food insecurity in Central Java using spatial
panel data analysis. Cross-section unit in this research is 35
regencies or municipalities in Central Java province which
was observed for 4 years (2007-2010) as time series unit.The
analysis result in this research show that fixed effect model with
SAR are better used for modelling food insecuity in Central
Java. This model show that production of paddy (X2) and
local government original receipt of regency or municipality
(X3) influence percentage of citizen with food insecure that
consume calorie under basic requirement 2100 kkal/capita/day
(Y) with R2 (95.88%). Coefficient of indicates that spatial
autoregressive effect significant in influencing percentage of
citizen with food insecure in Central Java.
