This service is based on changes in the mechanism and substance of the implementation of National Selection for Student Admissions (SNPMB). This transition is something new for prospective students and if prospective students do not understand it, it will 0certainly have a bad impact on the readiness of prospective students in participating in the implementation of UTBK-SNBT. The procedure for implementing the service is a sharing session on the implementation of SNPMB 2023, introduction and discussion of the 2023 UTBK-SNBT model questions, as well as an initial ability test on the representation of the 2023 UTBK-SNBT question model based on the latest UTBK-SNBT sub-matter. Then the socialization participants will be given a test to measure their knowledge of the SNPMB 2023 mechanism after the provision of SNPMB 2023 material. The results of this service activity are that more than 90% of prospective university students at SMA Negeri 1 Kefamenanu have understood the mechanism for implementing SNPMB 2023 after participating in the sharing session, based on the ability test, prospective university students do not fully understand the 2023 UTBK-SNBT model questions, and based on the results of the questionnaire, more than 90% of sharing session participants gave a good response to this activity. The results of this activity are important as a measure of understanding of the SNPMB 2023 mechanism and provide an overview of the initial ability of prospective students to answer UTBK 2023 model questions so that follow-up can be known in accordance with these abilities.

Salah satu metode pencarian solusi SPL yang dipelajari di pendidikan tinggi adalah metode Gauss-Jordan. Berdasarkan data penelitian, mahasiswa melakukan kesalahan dalam melakukan operasi baris elementer (OBE), membentuk ke dalam matriks yang diperbesar, dan bahkan pemahaman mendasar mengenai reduksi baris dan ini berpengaruh dalam menentukan solusi suatu SPL. Untuk itu perlu dianalisis hambatan belajar yang terjadi dalam menentukan solusi SPL menggunakan metode Gauss-Jordan. Peneitian ini merupakan penelitian kualitatif dan merupakan bagian dari Didactical Design Research (DDR). Penelitian ini dilaksanakan di salah satu universitas di Nusa Tenggara Timur (NTT) dengan subjek penelitian merupakan 20 mahasiswa calon guru matematika. Teknik penelitian ini adalah tes diagnostik dan wawancara. Hasil penelitian menunjukkan beberapa hambatan yang dialami mahasiswa adalah keterbatasan pemahaman pada OBE, pengklasifikasian MEBT, dan merepresentasikan MEBT ke dalam solusi SPL. Rekomendasi dari penelitian ini adalah pengajar hendaknya membuat suatu bahan ajar yang dapat meminimalisir hambatan belajar yang dialami mahasiswa. One of many methods of finding solution of a system of linear equations (SLE) studied in higher education is the Gauss-Jordan method. Based on the research, students made mistakes in performing elementary row operations (ERO), forming into augmented matrices, and even basic understanding of row subtraction and this has an effect on determining the solution of an SLE. For this reason, it is necessary to analyze the learning obstacles that occur in determining the solution of LES using the Gauss-Jordan method. This qualitative research is part of the Didactical Design Research (DDR). This research was conducted at a university in East Nusa Tenggara (NTT) involving 20 students as preservice mathematics teacher. The technique of this research is diagnostic test and interview. The results show that some of the obstacles faced by students are insufficient understanding of ERO, classifying reduced row-echelon form (RREF), and representing MEBT into SPL solutions. This study recommends that teachers create teaching materials that minimizes learning obstacles experienced by students.

The outcomes of situation analysis in SMP Negeri Kota Baru Kefamenanu East of Nusa Tenggara is the low achievement of students' mathematics learning outcomes seen from the evaluation results of mathematics subjects in the last four semesters and low learning motivation based on the results of teacher interviews. Therefore, we need an activity that aims to conduct training on math problems for grade 9 students and increase student motivation in learning mathematics. The drill method is a method for giving problems repeatedly. This method is considered relevant to the purpose of community service activities. The stages of community service activities begin with giving a pre-test, giving training on math questions, giving a post-test, and ending with giving a questionnaire regarding student motivation. The result of the community service activity was that there was an increase in students' understanding in working on math problems seen from a comparison of the results of the pre-test (29.05%) and post-test (94.76%) and students were increasingly motivated in learning mathematics refer to the results of the questionnaire. Based on the evidence, it’s crystal clear that service community activity is useful for training students to solve non-routine math problem and motivating students to learn mathematics.

One of the benchmarks of individual quality is seen in numeracy literacy skills. The purpose of this study was to identify the numeracy literacy skills of grade 11 students at Warta Bakti Kefamenanu High School, Nusa Tenggara Timur, in solving numeracy literacy problems with the minimum competency assessment (MCA) instrument in integral and domain algebra. This research was descriptive qualitative. This research technique was carried out with a test in the form of MCA, identifying the variations of errors made, identifying them in the types of errors, and mapping them to numeracy literacy indicators. Instrument items were taken from previous research and modified and content validity was done. The result of data analysis shows that participants who had principal errors met the numeracy literacy indicators item 1 and item 2, participants who had operating errors met the numeracy literacy indicator item 1, and participants who had conceptual errors did not meet all numeracy literacy indicators.BAHASA INDONESIA ABSTRACT: Salah satu tolak ukur kualitas individu dilihat dari kemampuan literasi numerasi.

This study purposed to describe the development and produce elementary linear algebra course modules on system of linear equation (SLE) and matrices integrated with Prezi learning media that are valid, practical and effective. This development research referred to the development design steps developed by Allesi & Trollip. The development design is grouped into three development procedures, which include: planning, design, and development stage. The product trial consisted of an alpha test conducted by two material experts and two media experts, as well as a beta test which was carried out through 2 stages, beta test 1 (small group trial) to 8 subjects; representatives of two students at cohort 2019/2020, 2020/2021, 2021/2022, and 2022/2023. Beta test 2 was conducted on 70 students who took the Elementary Linear Algebra course in cohort 2023/2024. Data collection used questionnaires for material experts, questionnaires for media experts, student response questionnaires, and tests. The developed module has several advantages. First, the material is prepared based on the results of research that has been done in previous studies so that it can minimize epistemological learning obstacles. Second, it is integrated with Prezi-based learning media that supports a deeper understanding of SLE content material.

The numeracy skill of elementary school students in border area Nunpene East Nusa Tenggara is still relatively low. This is caused by the studentsâ€™ 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
