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.

Abstract

Abstract This study aims to examine the effect of product variation and service quality on consumer repurchase interest at the Coffeville-Oishi Pan Magelang cafe. This study uses a quantitative approach. This study uses primary data obtained from 100 respondents as a sample selected based on the convenience sampling method. The data that has been collected was analyzed based on multiple linear regression analysis using SPSS. The results showed that product variations and service quality had a significant simultaneous effect on consumers' repurchase interest. The product variation has a positive and significant effect on consumer repurchase interest, but service quality has a positive and insignificant effect on consumer repurchase interest. The results provide managerial implications for Coffeville-Oishi Pan Magelang to increase product variety and improve health protocol-based services in order to increase consumer repurchase interest. With the increasing interest in repurchasing consumers, it is hoped that the cafe business that is run can develop and be sustainable. Abstrak Penelitian ini bertujuan untuk menguji pengaruhi variasi produk dan kualitas pelayanan terhadap minat beli ulang konsumen pada cafe Coffevillage-Oishi Pan Magelang. Penelitian ini menggunakan pendekatan kuantitatif. Penelitian ini menggunakan data primer yang diperoleh dari 100 responden sebagai sampel yang dipilih berdasarkan metode convenience sampling. Data yang telah terkumpul dianalisis berdasarkan analisis regresi linier berganda menggunakan SPSS. Hasil penelitian menunjukkan bahwa variasi produk dan kualitas pelayanan berpengaruh signifikan secara simultan terhadap minat beli ulang konsumen. Adapun variasi produk memiliki pengaruh yang positif dan signifikan terhadap minat beli ulang konsumen, tetapi kualitas pelayanan memiliki pengaruh positif dan tidak signifikan terhadap minat beli ulang konsumen. Hasil memberikan implikasi manajerial bagi Coffevillage-Oishi Pan Magelang untuk meningkatkan variasi produknya dan meningkatkan layanan berbasis protokol kesehatan agar dapat meningkatkan minat beli ulang konsumen. Dengan meningkatnya minat beli ulang konsumen maka diharapkan agar bisnis cafe yang dijalankan dapat berkembang dan berkelanjutan.

Abstract

This study explored ethnomathematics within the traditional tea processing in Banyumas Regency, aiming to examine its potential as a source for mathematics learning and its integration into instructional design. A qualitative ethnographic approach was employed at two sites: a home industry in Menggala Village, which processes raw tea leaves into semi-finished product, and another in Pasiraman Kidul Village, which refines semi-finished tea into consumable tea. Data were collected through interviews, observations, and documentation. Interviews were conducted with home industry owners to understand their techniques and knowledge related to mathematical concepts. Observations focused on daily activities, tools, and processes used in tea production. Findings revealed the presence of mathematical concepts such as geometry, measurement, ratios, decay, and set theory across various stages of tea production. Ethnomathematical activities identified included measuring ingredients, designing tools, counting quantities, determining optimal locations, and explaining procedures, which highlighted the relevance of traditional knowledge in mathematics education.

Abstract

Adolescents are an age group vulnerable to various reproductive health issues, including sexual harassment and the negative impacts of excessive gadget use. Gadgets are one of the results of technological advances in the modern era. While their use provides various conveniences and benefits, on the other hand, they also have negative impacts. The lack of education and supervision regarding these issues in the school environment presents a challenge in creating a safe and supportive environment for adolescent growth and development. This community service aims to increase the knowledge and awareness of Junior High School 15 Pekanbaru students regarding efforts to prevent sexual harassment and the dangers of wise gadget use on adolescent reproductive and mental health. Implementation methods include interactive counselling, group discussions, and the distribution of education media. Evaluation results showed an increase in participants knowledge about the definition, types of sexual harassment, how to prevent it, and the negative impacts of gadgets. The response from the school was very positive to this activity. It is hoped that this program can be the first step in sustainable development and be implemented in other school with similar methods.
