Regional minimum wages might well represent the economic development of a region. The most likely spotlight province regarding the wage determination issue is East Java. This work is intended to obtain the best regression model on factors influencing East Java's regencies/cities' minimum wages in terms of spatial approach. The methods are Spatial Autoregressive (SAR) and Spatial Error Model (SEM). This study aims to obtain the best spatial model based on the factors influencing the regional minimum wage in districts/cities in East Java and the mapping. The data source is secondary data from Statistics Indonesia (BPS) of East Java. It consists of several variables, namely the Regional Minimum Wage, Total Working Population, Gross Regional Domestic Product, Total Population, and percentage of Population with a minimum education of senior high school. It shows that two significant factors are the number of working civilians and the percentage of high school-college graduates, affecting regional minimum wages. It proves that minimum wages among regions in East Java are spatially correlated with a closed area. Spatial regressions are the better ones than classic ones since they have higher R-sq and satisfy assumptions. Meanwhile, the selected model is SAR rather than SEM as it has a smaller AIC and explains variation better in minimum regional wages. It is indicated that some regions need more care due to small regional wages.

Communication is an essential ability for every human being. In this study, the focus of communication was on students' mathematical communication. Mathematical communication is a person's ability to express their thoughts and is responsible for listening, interpreting, asking, and interpreting ideas from one to another to solve problems. This study aimed to describe the mathematical communication of Sombron Elementary School students in solving mathematical problems. This type of research is qualitative descriptive research. The research subjects were 23 students in class VI Sombron Elementary School. Three issues were selected for more in-depth analysis because they represented three categories: high, medium, and low ability students. Based on the subjects' works, the students could not communicate their mathematical ideas well yet. The most common communication error was a mistake in changing the word problem into a settlement model form. Based on the results and discussions that have been carried out with three different subjects, high ability student (ST), moderate ability student (SS), and low ability student (SR) of Sombron Elementary School at class VI, it can be concluded that ST and SS understand the meaning of the problem given and they know what was asked from the issue, but they did not use a correct symbol while writing their idea. ST and SS also made some mistakes in using mathematics symbols.
