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.

Mathematical terms in English often confuse students with their meanings. In its application, the impact on students' difficulties in understanding the concepts being studied. Students also have a problem in making useful conclusions while the books in English-language textbooks. These things make most Mathematics education students low-motivation and challenging to understand the concepts and basic mathematics derived from English-language texts. The term dictionary can be an alternative solution that can be used to overcome the problems. In general, the term dictionary discusses terms that are not common in a field. This Android application also provides a specific explanation of the terms that are the main search words. Android applications that have been developed are named RIGA. RIGA has 100 words or phrases in English and explanations and 100 words or terms in Indonesian along with answers. This study uses qualitative and quantitative data types. Qualitative data were obtained using a questionnaire in the form of suggestions and criticisms given by the test subjects. Meanwhile, quantitative data were obtained from questionnaire distribution scores from the test subjects. The results show that the results of validation by media experts and field trials produce valid results. Thus, it can claim that RIGA can use for the teaching and learning process.

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.

This study is expected to contribute to the health sector, specifically to describe the dynamics of the measles spread through the models that have been analyzed. One of the factors that became the focus of this study was reviewing the influence of population density on measles spread. The initial step formulated the model and then determined the primary reproduction number and analyzed the stability of the model equilibrium point. The results of the analysis of this model show that there are two conditions for the value of which is a requirement that the existence of two model equilibrium points as well as local stability is needed, namely and . When , there exists a unique equilibrium point, called the non-endemic equilibrium point denoted by . Conversely, when , there are two equilibrium points, namely and the endemic equilibrium point characterized by . The results of local stability analysis show that when , the equilibrium point is stable asymptotic locally. It means that if hold, then in a long time there will not be a spread of disease in the susceptible and vaccinated sub-population, or in other words, the outbreak of the disease will stop. Conversely, when equilibrium point is stable asymptotic locally. It means that if , then measles disease is still in the environment for an infinite time with the condition of the proportions of each sub-population approach to , , and .

The Jong Sailboat is a traditional game of the Riau islands' Malay culture. This game developed in various areas whose territories have beaches. In the Jong Sailboat game, mathematical elements can be explored, especially in the Jong Sailboat's shape. Mathematical practice in culture is known as ethnomathematics. Ethnomathematics studies can be obtained through exploration, exploring the field to get more knowledge from a situation. Through Jong Sailboat's exploration, mathematical concepts and elements are found in it. So this research aims to explore ethnomathematics in the shape of a Jong Sailboat as a traditional game in the Riau Islands. This type of study is qualitative research with an ethnographic approach. The subjects in this study were makers of traditional game crafters and the shape of the Jong Sailboat. Data collection is done by interview, observation, and documentation, with the main instrument of study, are the researchers themselves. The data is then analyzed by referring to Miles and Huberman's design by reducing data, presenting data, and conclusions/verification. The results found a mathematical practice in geometrical shapes in triangles, rectangles, and mathematical concepts in the way of translations, acute angles, right angles, trigonometry, straight lines, and slope. This exploration can enrich ethnomathematics science, which is also found in the form of Jong Sailboats.

The learning process is one of the essential things in students' success in obtaining the material they get, especially during the Covid-19 pandemic. Many students cannot carry out face to face in class. Therefore educators must provide the right method. So, students can understand the material it provides. Educators have used various ways not to feel bored, using the e-learning method. The study aims to determine Electronic-Based Mathematics Learning (EBML) for students' creative thinking ability in Sekolah Tinggi Keguruan dan Ilmu Pendidikan (STKIP) Muhammadiyah Pagaralam. The method used is the quasi-experimental method in the one-shot case study category. The study population was all students of the Mathematics Education Study Program of STKIP Muhammadiyah Pagaralam. The study results because of the indicator creative thinking indicators: fluent review 69.44%, flexible thinking 71.76%, original thought 74.92%, and elaborative thinking 88.19%. It is obtaining an average value of students amounted to 76,08%, it is categorized as useful. EBML is designed to simplify and shorten the learning process. So, it becomes more efficient. It is also to train students to be more independent in gaining knowledge to reach a wider geographical area, both in discussions and references. The EBML is applied to studentsâ€™ creative think in understanding the material presented.
