Description of Mathematical Reasoning Ability for Students of SMA Negeri 1 Tawangsari Class XI-MIPA 3 on Matrix Material

The purpose of this study was to determine how the students' mathematical reasoning abilities towards the matrix material. The data in this study were obtained from the results of filling out questionnaires and also interviews. Sources of data in this study were the subjects from which the data were obtained, namely students of class XI-MIPA 3 SMA N 1 Tawangsari. The data analysis technique used was data reduction, data presentation and conclusion drawing. The results of the data analysis from the questionnaire showed that the average percentage of student responses to mathematical reasoning abilities on the matrix material was 60.75% and was in the medium category. With the percentage on each indicator, namely on indicator 1 (students do calculations with the applicable mathematical formula / rules) of 55.63% so that it is included in the moderate category, students with the moderate category have aspects of the ability to understand question commands and are only weak at calculation operations. In indicator 2 (students draw general conclusions based on mathematical processes / concepts) the percentage is 61.25% so it is included in the medium category. In indicator 3 (students make estimates) the percentage is 81.25% so that it is included in the high category, students with high categories have aspects of the ability to understand question commands, question logic and can complete counting operations. While the percentage on indicator 4 (students draw conclusions based on the similarity of mathematical processes / concepts that are seen) is 54.5% so it is included in the low category, students with low categories have aspects of the question's melogical ability and are only weak in counting operations. The average percentage of the four indicators is 63.16% so that student responses can be said to be in the medium category. In this study, checking the validity of the data used triangulation techniques, namely by comparing the results of the study with the results of interviews. From the comparison of data analysis with questionnaires and interviews, it can be concluded that students with mathematical reasoning on the matrix material are in the medium category.

The purpose of this study is to describe the application of Reciprocal Teaching with role cards to improve student mathematical reasoning abilities on trigonometry material. Mathematical reasoning is thinking about mathematical problems logically to solve a problem and give reasons for a solution. One of the lessons learned to overcome the low mathematical reasoning ability is the learning of Reciprocal Teaching models using role cards. The steps of Reciprocal Teaching activities include question generating, clarifying, predicting, and summarizing. Before the Reciprocal Teaching steps are carried out, students are given a role card to determine the students who become model teachers. This research is a classroom action research. Based on the research that has been done, it is known that the application of the Reciprocal Teaching model increases the mathematical reasoning ability of students in XI grade IPA 2 of SMA Negeri 8 Malang on the Trigonometry with an increase in class average from initial 73 to 60 in cycle I and to 73 in cycle II. In addition, the average percentage increase in students' mathematical reasoning also increased from 60% to 73%.

This study aims to see the effect of realistic mathemathic education models on students' mathematical reasoning abilities in terms of learning styles. This type of research is quantitative. Data collection techniques used are essay tests and interviews. The data analysis technique used is hypothesis testing using anava 2 roads. However, before the anova test is carried out, the normality, homogeneity and balance test are carried out first. Based on the data that has been known that normal data, based on the same and balanced variance, the 2-way ANOVA test results show that there is an influence of the RTE model on students' mathematical reasoning ability, namely the reasoning ability of students with the RME model treatment is better than mathematical reasoning ability with conventional treatment methods. In addition, there is the influence of student learning styles on students' reasoning abilities.

Kata kunci : Inovasi Layanan, Drive Thru Perpustakaan, Budaya Literasi The library's drive-thru service innovation is a service created by the Library and Archives Office of East Java Province. This drive-thru service innovation is in the form of a counter to serve the needs of visitors without having to get off the vehicle. This innovation aims to facilitate service to users in the hope that it can improve literacy culture. The purpose of this study is to describe the drive-thru service innovation in the Department of Library and Archives of East Java Province. The focus of this research is the Innovation Criteria according to the Regulation of the Minister of Administrative Reform and Bureaucratic Reform (PermenPANRB) number 3 of 2018 covering 5 variables consisting of novelty, effectiveness, benefit, transferbility, and sustainability. This type of research is a descriptive type with a qualitative approach. For data collection techniques used are interviews, observation, and documentation. The data analysis technique used was data collection, data reduction, data presentation, presentation and conclusion drawing. The research results show that drive-thru service innovation has advantages and disadvantages. The novelty criterion indicates that drive-thru innovation is a new invention and offers a new way of serving visitors through the counter. . For the effective criteria, the purpose of creating a drive-thru is to make it easier for users to fulfill it, but to improve literacy culture has not been achieved. For useful criteria, it can provide benefits for the community and for the agencies that implement them. If this innovation can be replicated, it can be used as an example / reference because there are already several agencies that duplicate it. Then the last criteria for sustainability for the future of this innovation will be maintained because it has the support of various stakeholders. Suggestions that can be given are to promote more socialization so that this drive-thru can be more developed and utilized by more people.
