This study aims to describe the mathematical problem-solving ability of students in solving geometry problem of Programme for International Student Assessment (PISA). Subjects were selected by considering the result of the mathematics ability of 53 students in grade X through a preliminary problem. Then, the students was grouped into 3 categories: high-skilled subject, medium-skilled subject, and low-skilled subject. From each categories, the researchers picked one student as a research subject considering their communication skills to make researcher easy to describe the subects? process in solving the problem. The research was held by give each subject a geometry problem that is adapted from PISA problem, and then the researchers provide an interview for each subject. The results of this study analyzed by a descriptive qualitative method. The results showed that the high-skilled subject abled in understanding the problem, planning, and implementing strategy properly, as well as looking back in the calculation section. For the medium-skilled subject already made mistakes in understanding and planning the problem, so that the subject implemented the wrong strategy, besides the subject corrected to the concept only. The low-skilled subject made mistakes in understanding and planing the problem so that the subject implemented the wrong strategy. In addition, the low-skilled subject did not look back at his work.

The research aims to depict students’ ability in solving mathematical problems based on Polya’s heuristic. Descriptive qualitative was used as a method in this research. Data were collected by observation, test, and interview. Based on the result of analysis obtained that the students with low level prior knowledge think heuristically in solving the problem solving test. For the students with medium level prior knowledge, the students think algorithmically and couldn’t solve the problem solving test imperfectly. Furthermore, the students with high level prior knowledge think algorithmically in solving the problem solving mathematics test and the other words, the students could solve the problem solving test well and fluently.

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.

The purpose of this community service activity is to provide socialization on the work of UTBK with math magic techniques in SMAN 1 and SMAN 2 Kefamenanu. Furthermore, the background of this socialization is to improve the students' reasoning ability through familiarizing themselves with students solving non-routine problems found during the implementation of UTBK, especially in mathematics. This community service was carried out from January to March 2020 with 40 participants. This activity consists of three stages starting with the assessment of the field, the implementation phase and finally the evaluation phase. In the field assessment stage, the servant determines the participants of the socialization, which is specifically for high school students of class xii, prepares administration, prepares materials and UTBK questions and then prepares a schedule. The second stage is the implementation phase in the form of a brief exposure to the UTBK, then giving samples of the UTBK questions for students to work on and scribing questions. The last stage is the evaluation stage in the form of an evaluation of the implementation of activities that have been arranged based on each task that has been given. Based on the socialization activities that have been carried out it can be concluded that these training activities increase students' knowledge about UTBK and add student skills in working on math UTBK questions . In addition, this training motivates students to be more active in learning mathematics and to be more mature in preparing for the upcoming UTBK.

The numeracy skill of elementary school students in border area Nunpene East Nusa Tenggara is still relatively low. This is caused by the students’ habit use counting aid such as calculators. Therefore, it is necessary to have a Lecturer activity in the community to help elementary school students which aim to improve their numeracy skills. Because mathematics teaches various skills, one of which is counting. So that the ability to count is a fundamental thing that must be mastered by students when they learn mathematics. One of learning method that can be done to improve students' numeracy skills is by applying the Jarimatika method which involves the students' own organs directly. Indirectly cognitive and psychomotor abilities will develop simultaneously so as to increase the efficiency of students' counting speed. As for the steps of the service, the method are including the introduction of the counting method, assistance during the learning process, then providing an evaluation. The results of this training are that after the training, it can be seen from the posttest results that students have increased their numeracy skills using the Jarimatika method. As well as increasing the knowledge of mathematics teachers regarding the use of the Jarimatika method as an alternative method of numeracy
