Abstract

The objective of this research is to know the application of SEM (Structural Equation Model) analysis in seeing reliability and validity of causal relationship among latent variables  in the area of marketing management of health service industry influenced by patient perception about health service quality on patient loyality with satisfaction of patient as the medium variable. SEM Analysis is a group of statistical techniques which is conducive to be done examination a relation network which is complicated relative simultaneously. In SEM, we can do three activities simultaneously, that are  inspection and validity of reliability equivalent instrument with confirmatory factor analysis, examination of relationship model among latent variables equivalent with path analysis, and get worthwhile model for predicting equivalent with structural model or regression  analysis. The conclusion of got from this research is there are influence which significant among the perception of patient to the patient loyality, the perception of patient to the satisfaction of patient, the satisfaction of patient to the  patient loyality.Keywords: Structural Equation Model, reliability, validity, confirmatory factor analysis, path analysis.

Abstract

Many classical data, for example, exchange rate, stock price, and consumer price index (CPI) data cannot be analyzed under independent observation assumption. In addition, some time series data cannot be modeled well into a fully linear model, for instance, CPI, price of raw materials for some certain industries and price of some industrial products data in which monetary crisis of Indonesia in 1998 has caused a dramatic effect on the time series of CPI, price of raw materials and industrial products. A semiparametric model is a mixture model between parametric and nonparametric models. If we apply it to time series data, we will obtain a semiparametric time series model known as partly linear autoregressive model: y1= β yt-1 + g ( yt-2 ,..., yt-p ) + εt for t > p + 1. Here β is an unknown parameter to be estimated, g(.) is an unknown function in Rp-1 , εt are i.i.d. random errors with E ( ε1 ) = 0 and E ( ε12 ) < ∞, and εt are independent of ys for all s = 1 , 2 ,..., p and t > p + 1 . Based on the model above, we investigate a model for general consumer price index (GCPI) of Jember data recorded monthly from January 1998 to December 2002 by Statistic Center Bureau of Jember.

Abstract

The purpose of this study was to determine the effectiveness of substantive technical education and training program for Islamic High School (Madrasah Aliyah/MA) throughout Central Java and Yogyakarta. Quantitative research with "One-Group Pretest-Postest Design" research design was used. Population and samples were taken from all Biology teachers throughout Central Java and Yogyakarta with a total of 33 participants. Instruments for data retrieval were questions about pretest and posttest. The data were in the form of participants’ pretest and posttest results. Based on the Wilcoxon test results, it obtained t count -3.083, while p = 0.002 <0.05, it could be concluded that substantive education and training can effectively improve the material mastery for Madrasah Aliyah biology teachers. The materials were the analysis of Graduate Competence Standard (SKL), Core Competence (KI), Basic Competence (KD), Biology Indicators of Madrasah Aliyah, essential material of anatomy and physiology of animals and plants, cells, animal and plant tissues, metabolic processes, biotechnology and their application, genetic in inheritance, and the practice of Madrasah aliyah biology learning.
