Abstract: This study aim to describe the thinking process of elementary school fifth grade students in solving mathematics problem based on Krulik and Rudnick rule. This research was a qualitative research using the case study method. Sampling was done by a combination of purposive sampling and snowball sampling technique. The subject of research that used in this study was twelve subjects, that was: four high-ability students, four moderate-ability students and four low-ability students. The data was validated by using a time triangulation test. The results show: (1) At the step of reading and thinking, students do not directly identify all of the facts in writing. After identifying the facts, students identify questions from the given problem. Furthermore, students do not portray the problems encountered but directly process the needed information to answer the question; (2) At the step of exploring and planning, students organize the information on the matter. Students consider enough information on the matter because there is a relation between the known and the asked. On the other hand, students do not make tables, diagrams, charts, tables or images from a given problem, but directly chose a strategy to answer the question; (3) At the step of selecting the strategy, students use the making list of all possible answers strategy. Students write down all the possibilities answers in the answer sheet. However, there are students who also use the guessing and testing strategy, guess how the value of variable and test whether the variable value is correct. In addition there are also students who use simulation or experimental strategies, students try to experiments; (4) At the step of finding the answer, the student use estimation in finding the answer. On the other hand, there is one student who uses algebra ability to find the answers. Students are also assuming the third day as a variable. After obtaining the value of the variable, student examine whether the numbers are correct. (5) At the step of reflecting and extending, students can review the results of the calculation by return on the answer sheet. Then students find that the answer is correct. Furthermore, students assume no alternative other solutions. Then the students do not make a generalizations of matter and discover the concept of matter.Keywords: process thinking, mathematics and problem solving.

The covid-19 pandemic period like now requires to find an alternative learning that is effectively used. It drives a changing method of learning from face-to-face to online. One alternative in learning today is the use of smartphones or commonly referred to as mobile learning. This study aims to determine: 1) differences in student mathematics learning achievement with learning through mobile learning and google classroom, 2) interaction between learning through mobile learning and the ability to work together with students towards mathematics learning achievement, 3) differences in student mathematics learning achievement at the level of ability cooperate. The subjects of this study were students of the Mathematics Education Study Program STKIP Pamane Talino who took 68 Integral Calculus courses consisting of 2 classes. The research was conducted in 5 meetings. Each group was taught with the same material. The instruments in this study were test and questionnaire. The research method used was quasi experiment with 2x3 factorial design approach. The data analysis test used was the two-way ANAVA test with the analysis prerequisites in the form of a normality test and a homogeneity test. The results of data analysis show that the data are normally distributed and homogeneous. Thus, it can be concluded that: (1) learning with Mobile Learning media is more effective than learning with Google Classroom media, (2) the level of ability to work together high, medium and low gives different effects on student mathematics learning achievements and (3) students with all levels of ability to work with learning media Mobile Learning and Google Classroom provide equally good learning achievements.

Indonesia has enormous potential to develop the tourism sector. The role of the tourism sector in Indonesia's economic development is increasingly important. The contribution has been made by the tourism sector through foreign exchange earnings, regional income, regional development, investment, and employment increment as well as business development across various areas in Indonesia. One of the government's targets in the tourism sector is to increase foreign tourist visits. Grouping or clustering the countries of origin of the tourists need to be done to help the government in determining strategies. This study uses the K-means clustering algorithm to classify the data on the country of origin of tourists and evaluate the clusters using silhouette score for determining the appropriate number of clusters. The result of the silhouette score shows that K = 2 has a value of 0.8, which is the best cluster that can be used to classify data on the country of origin of tourists. Based on the test results of the clusters, both of the clusters were then identified as cluster 1 for the category of low visitors with 206 members and cluster 2 for the category of high visitors with 6 members, namely Malaysia, Singapore, China, Other Asia, Timor Leste, and Australia. The results of the clustering process are expected to be input data for further performance, namely mapping the right marketing strategy for the countries visiting Indonesia so as to increase foreign tourist visits to Indonesia.

We investigate a graph labeling called the total vertex irregularity strength (tvs(G)). A tvs(G) is minimum for which graph has a vertex irregular total -labeling. In this paper, we determine the total vertex irregularity strength of disjoint union of ladder rung graph and disjoint union of domino graph.

The data collection techniques used were observation, interviews, and questionnaires. The subjects of this research were 120 students in the first semester of the Mathematics Education Study Program FKIP UMS academic year 2018/2019. The results of this study were in the form of a calculus interactive learning media with Schoology pseudo-class. The application of technology with Wolfram CDF and Schoology helps in learning activities. A total of 87 students stated that the learning media was very good and 33 students stated that the learning media was good. With the pseudo classroom learning used, students also get several other benefits in online classroom learning including an understanding of information and technology skills.
