Estimation of Percentage on Malnutrition Occurrences in East Java Using Geographically Weighted Regression Model

The Province of East Java has its own characteristics that differentiate it from any other regions. Dissimilarities in characteristics of a region may encompass issues such as social, economic, cultural, parenting, education, and the environment, so as to cause the difference in case of severe under nutrition between one region to another. Sufferers of malnutrition in one region may be linked and influenced by the surrounding regions. Therefore, we need a statistical modeling that is able to take into account the spatial factor. Statistical methods that can be used to analyze the data and also takes into account the spatial factor are the Geographically Weighted Regression (GWR). This study is aimed to determine the case of malnutrition models in East Java Province using GWR model with kernel adaptive bi-square weighting and comparing it to the conventional linear regression model.  The data used in the study are secondary data obtained from the National Socio-Economic Survey and Basic Health Research (2010) conducted in 38 districts in East Java. Estimation is done by using the Weighted Least Squares method that provides different weighting values to each region. The result showed that there are 38 models of the malnutrition case that is different for each district in East Java. The GWR model with bi-square kernel weighting function is better in modelling the case of malnutrition in East Java compared to the conventional linear regression models that are based on the criteria of goodness that is the R-square, Mean Square Error and the Akaike Information Criterion

Identifikasi Prediktor Pola Hidup Bersih dan Sehat Siswa Sekolah Menengah: Eksplorasi Data Sekunder Lomba Sekolah Sehat

Strengthening character education becomes important thing nowadays as stated in Presidential Decree No. 87 year 2017. Student\u27s clean and healthy lifestyle reflects from their mind and character. To implement the character education, there are many factors involved in it. The purpose of this research is to identify the variable predictors of student\u27s clean and healthy environment considering teacher role model variables as intervening variables. The analysis of this relationship pattern is based on an interactionist perspective arguing that student behavior does not occur in isolation, but as an impact of interaction results. School environment is faced daily by students. The intensity of this interaction can lead to healthy and hygienic behavior habits through teacher\u27s role model. Regression analysis used to prove the perspective of interactionist is based on secondary data of Healthy School Competition period 2016 and 2017. This competition is a junior high school and high school/vocational school competitions representing the province to be included in the national competition. The data used in this study comes from an observation instrument filled by Healthy School Competition Officers at the National level, and students at schools designated as provincial representatives. Students who were selected as subjects were selected randomly. By using regression analysis, empirical tendency showed that school environment factor namely clean and healthy environment become predictor to the formation of student\u27s clean and healthy behaviour

Managing Rewards to Enhance Customer Value: Empirical Study of Frequent Flyer Program

. The goal of relational program is to retain customers who are profitable to the organization. Reward point is a form of customer loyalty widely used by many industries including airline industry. Airline loyalty program, notorious as Frequent Flyer Program (FFP), is the most sophisticated marketing strategic used by airline industries nowadays. However most airlines have very little understanding of their FFP members yet have a little knowledge about their most valuable customers. Most airlines have inaccurately determined the customer values by only considering business worth of nominal profit generated by FFP members. The value of customers beyond purchasing behavior - called relational worth - has not been commonly captured yet. This non-financial value is predicted as a driver in retaining customers, hence becomes one of crucial factors in preserving the profitability of the organization. For this reason, this paper aims to examine the customer non-financial valuations of FFP members to the airline. The hypotheses are empirically tested with a sample of FFP members of respected airline conducted through online survey (n=475). The data were statistically analyzed using structural equation modeling (SEM). Results indicate that perceived rewards generate higher value of relational worth through indirect relationship by intervening variable of relationship quality than that of generated by a direct relationship

Model Pengendalian Mutu Lahan Kering Berbasis Pemberdayaan Masyarakat Di Kabupaten Ponorogo

To control quality of rainfed areas as well as improvement of farmers\u27 welfare is efforts already has been done by local government (Ponogoro) however it\u27sstill not success yet because it used to partial approach. Therefore, it is very important to research and develop model how to control quality of rainfed based on community empowerment with integrated (system) ap­proach.The location of research is in Ponorogo Districtwith 326 respondens, consist of 6experts, 20 linkage agencies staff and 300 farmers. Beside useAnalytical Hierarchy Process (AHP), Interpretative Structural Modelling (ISM), and System, this re­search also use univariat and bevariate analyze (Chi- Square and Structure Equation Model- SEM).Based on data and informa­tion that collected and analyzed, this research develop model that reflected the the real situation (fact), that can be simulated and validated. The model is established with system approach of population, local government services and ecology. The model vali­dated by absolute mean error (AME) and absolute variation error (AVE) that reflected variance between actual and value from model less than 10%, it show the model is a valid.This mean model able to simulate any changing of rainfed areas quality con­trol both in short or long term period.Other significant factors that related with rainfed areas quality control is farmers know­ledge (p-value= 0,030) and farmers behavior (p-value=0,040).The empowerment of farmers indicated by food and nutrition security (γ = 1), settlement and sanitation security (γ = 0.23), healthy security (γ = 0.01)and education security (γ = 0.24). The empowerment of farmers influenced by coping strategy (β=0.41), that reflected by how farmer survive in production, consump­tion and marketing of agriculture with respective of γ is0.59, 0.27, 037 and 0.42. In line with these statistic analysis AHP, ISM results and validation model, this research formulated empowerment policy focus on life skill development through farmer group. In the beginning process of life skill development focus on soft skill and then hard skill later on up to achieve sustainable self help group in managing their rainfed areas
