A great school and accordance with the character of the child will be able to guide children toward a better future. There are many factors that influence parents in choosing a kindergarten school for children affected from both the internal parents, schools or internal environment. The author would like to see the factors that influence whether parents in choosing a kindergarten school for children and whether there is a relationship between internal indicators of parents, school internally, and the environment. Internal indicators of parents, school internally, and the environment in question include: parent education, parental employment, parental income, school programs, teacher background, facilities, location, promotion, reputation, cost, references, traditions, parents and the learning process. The analysis used were factor analysis and canonical correlation analysis. The results showed that there are seven factors that influence parents in choosing a kindergarten school which factors socio-economic background of parents, location, teacher backgroud, school status, environment, state school, and cost factors. Result of canonical correlation analysis showed that between internal indicators parent with internal school, among parents with the internal environment, and the relationshipbetween internal school and environment provides each significant effect.

Abstract

Linear Regression Analysis is a statistical method for modeling relation between two variable, response and explanatory variable. Geograpically Weighted Regression (GWR) is the development of linier regression analysis if the case of spatial divers case. Local multicollinearity is a condition when explanatory variables had correlated with each observation location. Geograpically Weighted Ridge Regression (GWRR) is a method used to model data containing local multicollinearity on spatial data. GWRR model was developed from ridge regression by adding weight as additional information. The study aims to model spatial data containing local multicollinearity to the Human Development Index (HDI) in the districts/municipalities of eastern Java Province in 2015. The result of this study was indicate that the indicator of the average length of school is a dominant indicator that affects HDI.

Abstract

Information about tourist visits, especially foreign tourist visits, plays important role in tourism planning. One of the main tourist markets for Bali is Australia. The aims of this research are twofold. First, we forecast the number of Australian tourist visits and we also forecast exchange rate and inflation. Second, we study the dynamic relationship between the number of tourist visits, exchange rate, and inflation for the next twelve months, for instance, 2017 and 2018. We model the visits, exchange rate and inflation using Bayesian vector autoregression. We compare several different priors such as Minnesota, normal-Wishart and normal diffuse independent normal-Wishart. Among these priors, the normal-Wishart prior produces the smallest root mean square error. Hence, the normal-Wishart prior was chosen as the prior of choice for our Bayesian Vector Autoregressive model. The forecast shows that there is a decline in the number of tourist visits, but inflation and exchange rates tend to reach a certain level, for instance, stabilized. The impulse response function shows that there were shocks in the beginning period before reaching zero.

Abstract

Indonesia's cultural wealth as an ancestral heritage requires protection so that the values of wisdom are preserved. In the era of globalization, education has an important role in shaping character and passing on cultural heritage. The ethnomathematics approach, which combines mathematics and culture, is a bridge to integrate culture in education. An ethnomathematics exploration of the Monument to the People's Struggle in Bali reveals mathematical concepts in the structure of the historic building. This research used an ethnographic and exploratory approach with a focus on the Bali People's Struggle Monument. Data consisted of observation, literature study, and documentation. Analysis was conducted to identify mathematical concepts, especially in geometry, using a taxonomy approach. The Monument to the Struggle of the Balinese People reflects the story of the play of Mandara Giri with the symbols of Lingga and Yoni. The building structure has an 8-square plan and the Asta Dala lotus flower. The symbol of struggle is reflected in the number of steps, the Supreme pillar, and the height of the monument, depicting the date of the Proclamation of Indonesian Independence. In the ethnomathematics exploration, geometry concepts such as square, octagon, right triangle, trapezoid, rectangle, circle, isosceles triangle, parallelogram, and tube were identified in the building structure of the Bali People's Struggle Monument.
