Universitas Nahdlatul Ulama Sunan Giri (UNUGIRI) has many students who have achievements. The number of outstanding students is a problem in determining the decision-making of outstanding students. One of the effective decision-making methods for solving problems in selecting outstanding students is the Analytical Hierarchy Process (AHP) method. The AHP method in this study considers four criteria: Grade Point Average, Writing Paper, Achievement (Non-Academic), and SPEKMA points. Out of 73 UNUGIRI students who had achievements, a ranking was carried out into ten alternative students. The results of calculating ten alternatives based on four criteria with the AHP method obtained the highest score of 0.1437 for students with the name PWA. Based on these results, PWA can be designated as outstanding students for the 2021/2022 academic year.

Students’ difficulty in calculus can be related to their ability in covariational reasoning in school or college. Reasoning process involves high-level cognition. Nevertheless, the relationship between cognitive style and covariational reasoning has not been investigated more specifically. Cognitive style in this study was characterized by field-dependent and field-independent category. This paper describes the covariational reasoning process of field-dependent and field-independent students while constructing the graph of dynamic events. Students’ cognitive style data obtained through the Group Embedded Figures Test (GEFT), while the covariational reasoning data obtained through the covariational problem test and verified by several interviews. The results showed that there was no significant consistent difference between field-dependent and field-independent students in their covariational reasoning level, but there were differences in students’ way of reacting to the context of the problems. Field-dependent subjects exhibited their mental action inconsistently when they faced a new problem that more complex than before. This finding indicated that we need to set the problem to make it an effective stimulus in developing student’s covariational reasoning ability.

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.

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.

Patterns generalization learning at the junior high school is more emphasis on the generalization of linear patterns. One problem in generalizing linear patterns is that students do not know the process of using trial and error strategies to generalize linear patterns. For this reason, the purpose of this study was to analyze the thought processes of 2 junior high school students who succeeded in generalizing linear patterns using trial and error strategies. The results show that there are two trial and error strategies that can be used to generalize linear patterns, namely: (1) Trial and error strategy by looking at the relationship of quantity consists of three steps. The first step is called relating, namely, the subject connects between the first term, the term in question, and difference. The second step is called searching, where the subject finds similarities by using addition and subtraction operations to obtain the nth term formula. The third step is called extending; the subject expands the pattern into more general structures by looking at the relationship between quantities. (2) Trial and error strategy by looking at patterns that consist of three steps. The first step is called relating, namely, the subject connects small positive integers by using arithmetic operations to obtain the first term and the second term. The second step is called searching, where the subject finds similarities by finding the formula for the first, second, and third terms. The third step is called extending, where the subject expands the pattern into more general structures by looking at the pattern that applies to the first, second, and third terms.

The development of the curriculum is a dynamic process which aims to comply with the evolvement of knowledge and technology. However, the implementations of the reformed curriculum have been acknowledged to raise various issues. Likewise, among the issues related to the implementation of the Curriculum 2013, known as K13, in Indonesia was teachers’ difficulties, including mathematics teachers. This study aimed at investigating and describing the difficulties faced by junior high school mathematics teachers in implementing K13. The study applied a mixed-method approach involving 66 from a total of 78 junior high school mathematics teachers in Lhokseumawe, Aceh Province, as the study sample. The findings showed that 50%-60% participants encountering difficulties in components of training and socialization of K13, lesson planning, learning activities, and assessment and reporting the learning outcome. Although 93.94% teachers have taken the K13 training, only 56.45% of them sometimes implemented the curriculum in the classrooms. Additionally, the main resource of the difficulties was the ineffectiveness of training and socialization of K13 the teachers had attended. The teachers expected that there would be a learning community or forum as the follow-up action of the training, which can supervise the implementation of K13 in their classes. The directions for further research to improve curriculum implementation were discussed.
