Abstract: Spatial regression model is a regression model that is formed because of the relationship between independent variables with dependent variable with spasial effect. This is due to a strong relationship of observation in a location with other adjacent locations. One of assumptions in spatial regression model is homogeneous of error variance, but we often find the diversity of data in several different locations. This causes the assumption is not met. One such case is the poverty case data in Central Java Province. The objective of this research is to get the best model from this data with the heterogeneity in error. Ensemble technique is done by simulating noises (m) from normal distribution with mean nol and a standard deviation σ of the spasial model error taken and adding noise to the dependent variable. The technique is done by comparing the queen weighted and the cross-correlation normalization weighted in forming the model. Furthermore, with these two weights, the results will be compared using R2 and RMSE on the poverty case data in province of Central Java. Both of weights are calculated to determine the significant factors that give influence on poverty and to choose the best model. The results of the case study show that the spatial regression model of the SEM ensemble already does not have a variance error that is not homogeneous and the model using cross-normalization weight is better than the spatial regression model of SEM ensemble with Queen contiguity weight. 1 INTRODUCTION obtained without considering the spatial effect then the conclusions obtained will be invalid. Regression modeling is one form of classical Models with spatial effects have been proposed by modeling that is used to provide a model of the Qu (2013), i.e. the Spatial Auto Regressive (SAR) relationship between independent variables with model which shows the dependence of observation on dependent variable. Fulfillment of the assumptions of the dependent variable (autoregression) between the this modeling is necessary to ensure that the model is locations. While Mac Millen (1992) discusses the good and can be used for prediction. The problem that model of Spatial Error Model (SEM) which indicates often arises is when the model does not meet the an error correlation between locations. necessary assumptions.

The factors are: General Allocation Fund, government expenditure, investment, quality of human resources, agglomeration, and labor. The analysis tool used ist the regression of data panel/pooled data with the approach of Least Square Dummy Variable (lSDV). This approach is used because it is in accordance with the aim of research, which is to know the role of the economic growth factors to the GDP and to know the rate of economic growth from 2004 to 2013 in the West Pantura (northern coastal) areas of Central Java. From the estimation, it is known that the economic growth factor of human resource is the one that influence the GDP ipm with coefficient of 0.199316 percent, followed by the labor factor with coefficient of 0.165086 percent, an investment of 0.0013066 percent and the government expenditure with coefficient of minus 0.019731 percent. However, the General Allocation Funds does not have much influence on the economic growth, only at 0.009572 percent. Whereas, the agglomeration has no influence on the role of the GDP and on the economic growth in the West Pantura areas of Central Java.

Flora no. 1, Bulaksumur, Sleman, Yogyakarta 55281 *Corresponding email: [email protected] Received: 4 th March 2016 ; Revised: 15 th March 2016 ; Accepted: 23 rd January 2017 ABSTRACT It takes into account in potato farming sustainability, since it was recognised as a holticultural commodity for farmers’ subsistence in Wonosobo Regency. For the reason that farming land was being degraded by errossion, the potato productivity apparently continued to decline. Potato farming sustainability can be deliberated from economic (profitability) and environmental (conservation efforts) points of view in order to remain profitable in a long term sustainable environment. This study is aimed to (1) to analyse the profitability of potato farming; (2) to analyse farmers’ effort on soil conservation and factors which affected sustainability of potato farming. The method used in this study was basic descriptive analysis. The study site was in Kejajar District, Wonosobo Regency, subsequently 50 random farmers as respondences was obtained. Gross Margin, Return on Invested Capital, and Operating Ratio were used to measure the profitability of potato farming. Conservation Activity Index (CAI) was used to measure farmers’ effort on soil conservation, while paired liner regression model with Ordinary Least Square (OLS) method was used to understand the factors which affected the conservation efforts of test sites.

Administratively, it covers Se- marang Regency, Salatiga City, and Boyolali Regency. Industry and community use groundwater to fulfil their daily need. Increasing number of deep wells that extract groundwater will cause some environmental problems, such as lowering groundwater level and subsidence at SGB. Thus, there is a need to assess the adverse impacts of groundwater abstraction. Risk assessment of groundwater vulnerability due to abstraction is the goal of this study. The research method was taking account of weighting of geological parameters, such as response characteristics of the aquifers, characteristics of aquifer storage, aquifer thickness, piezometric depth, and distance from the shoreline to conduct the groundwater vulnerability mapping. It was then overlaid on a map of regional spatial plan to develop the map of vulnerability risk due to abstraction. The groundwater vulnerability due to abstraction is categorized in the medium level. After being overlaid by the land use map, the risk of groundwater vulnerability due to abstraction is classified into three kinds, which are low, medium, and high.

This is very reasonable considering that no television has been established in Surakarta. On April 29, 2004, TATV began broadcasting on air, and was called "Jelang Tayang Perdana". At the start of launching on air or the trial broadcast by TATV it still seemed to be less professional. There are no programs that can be presented such as national television, only limited to advertisements in the form of slides. The screenings are still very simple and not very interesting. In addition to image quality, it may be due to the lack of human resource management.

Budi Prasetyo dan Arif Sofianto Badan Penelitian dan Pengembangan Provinsi Jawa Tengah email: [email protected] ABSTRACT One of the main critical issues in a decentralized development today is the failure of family planning programs that are affected by its institutional forms. This study aims to develop a formula institutional revitalization of family planning program managers are required at this time. The method used in this research is descriptive qualitative models using Spradley’s analytical techniques. This research was conducted in Pekalongan Municipal, Wonosobo Regency, and Purworejo Regency. The conclusion of this study is that the deterioration of family planning programs in the area due to lack of commitment from local leaders, organizations do not focus in carrying out its functions, especially the field staff (field officers), lack of resources and synergies in the implementation of the program. Chief policy areas are very influential in determining the shape of the organization, resource allocation and implementation of synergies. Institutional revitalization needs to be done by the local government is established agencies that focus on population and family planning affairs so that the implementation in the field (field officers) are more focused on family planning matters, but on the other hand still have to pay attention to the ability of the region and some other matters. In addition to the organization in the form of focus, also need to be supported adequacy of resource allocation and increased synergy among sectors fostered by regional heads.
