Abstract

The problem of food insecurity has long been the focus of attention and is very closely related to the problem of poverty in which the two are interrelated phenomena that have a causal relationship. Food insecurity and poverty is a package that is always the problem faced by the government both central and local government, especially in Sampang. Spatial regression models that have been described in general a univariate spatial model, in which the observations have only one response variable that depends on the location of the observation. Geographically Weighted Multivariat Linier Model a multivariate regression models were used to spatially resolve the influence of spatial heterogeneity caused by differences in the conditions of the location with another location. The purpose of this study was to establish Geographically Weighted Multivariat Linier Model (GWMLM) with a weighted cross – variogram gaussian on the problem of food insecurity and poverty in Sampang. Food insecurity and poverty is a phenomenon of spatial heterogeneity.  Based on the 10 sampled villages gained influence the percentage of households without access to electricity (X1), the percentage of main roads are adequate (X2) , the number of health facilities (X3) , and the percentage of malnutrition children (X4) against food insecurity and poverty differently in each location.

Abstract

Tetanus Neonatorum (TN) is an infectious disease that could be prevented by immunization. East Java Province is the highest numbers of TN case in Indonesia. TN data in East Java contain overdispersion and big proportion of zero-inflation (71,05%). The data containing overdispersion and zero-inflation are more appropriately analyzed by using Zero-Inflated Negative Binomial (ZINB) regression. The aim of this study are: (1) to know the perform of proportion of zero-inflation for ZINB model and (2) to obtain the optimal proportion of zero-inflation for TN data. The result of this study indicates that the optimal proportion of ZINB model is 64,52%.

Abstract

An organic matter is one of the main components of soil. It is very potential to influence condition or type of soil and further it helps the growth of plants. One of methods which can be used to measure the levels of organic matters in an area is remote sensing technology and Geographic Information Systems (GIS) by using satellites. Analysis could be done in two steps. First, in statistically analysis by using regression models. The equation models of C-Organics level in -0,849 + 0,017X1 - 0.008X3 + 0.011X4.  Second, in spatial analysis, it is to know the C-Organic distribution, and also using interpolation with spatial analysis technique which is Inverse Distance Weighted (IDW) methods. Next, testing a model estimation which have been obtained in Sampang. Through the validation analysis using t-paired test, resulting estimation model which have been obtained is able to estimate the C-Organic levels in Sampang which could be an alternative way to estimate the C-Organic levels in same area.
