Abstract

The study aims to determine the set of the singular matrix 2×2 that forms the group and describes its properties. The type of research was used exploratory research. Using diagonalization of the singular matrix S, whereas a generator matrix, pseudo-identity, and pseudo-inverse methods, we obtained a group singular matrix 2×2 with standard multiplication operations on the matrix, with conditions namely: (1) closed, (2) associative, (3) there was an element of identity, (4) inverse, there was (A)-1 so A x (A)-1 = (A)-1 x A = Is. The group was the abelian group (commutative group). In addition, in the group, Gs satisfied that if Ɐ A, X, Y element Gs was such that A x X = A x Y then X = Y and X x A = Y x A then X = Y. This show that the group can be applied the cancellation properties like the case in nonsingular matrix group. This research provides further research opportunities on the formation of singular matrix groups 3×3 or higher order.

Abstract

This study aims to describe the online mathematics learning process and to find out the mathematics learning outcomes in terms of the mathematics disposition of class XII IPA students at SMA Negeri 7 Mataram. This type of research is descriptive qualitative. All students of class XII IPA at SMA Negeri 7 Mataram are the population, where the sample size is 62 students who were selected by cluster random sampling rule. Data collection used a questionnaire, interview and documentation study. From this research, the results show that: (1) The learning process carried out by the teacher changes from direct learning to online learning. In the online learning process, there are several difficulties experienced by students, including students who do not understand the material presented by the teacher, whether the material is delivered in the form of a pdf or video that has been shared. In implementing the online learning process the teacher is not the only source of learning so students are actively looking for other learning reference sources such as videos on YouTube and websites. Assessment of learning outcomes is carried out by providing a written test of the test resulting in that there is no increase in student learning outcomes during learning with an online system. The implementation of online learning cannot be separated from the supervision of parents and teachers. (2) There is a correlation between final semester test scores with students' mathematical dispositions.

Abstract

The purpose of this study was to determine the effect of a mind mapping-assisted problem-based learning model on the problem-solving abilities of class IX students at SMP Negeri 1 Gunungsari in the 2020/2021 school year. This type of research is a pre-experimental research using a one group pretest-posttest design. The population in this study were all grade IX students. While the sample in this study is class IX E with random cluster sampling. Based on the results of the pretest and posttest data analysis in the experimental class, it can be seen that the students' mathematical problem solving ability has increased by an average of 27%. Meanwhile, the results of the pretest and posttest data analysis in the control class increased by an average of 9%. Based on the results of hypothesis testing, it is obtained that the value of ttable with a significant level = 5% and dk = 12 from the t-distribution list obtained ttable of 1.78 and tcount of 5.40 which means tcount > ttable, then H0 is rejected so H1 is accepted. This means that there is an effect of the problem-based learning model with the aid of mind mapping on the problem-solving abilities of class IX students at SMP Negeri 1 Gunungsari for the 2020/2021 academic year.

Abstract

This study aims to determine the effect of verbal ability and numerical ability, the effect of verbal ability, and the effect of numerical ability on the ability of solving linear equation system problems. This study is an ex post facto research. The population of this study were students of class XI SMAN 9 Mataram. The sample in this study were 28 students of class XI SMAN 9 Mataram represented by four students in each class. The data analysis used is multiple linear regression analysis and simple linear regression analysis. From the results of the data analysis, there is a significant influence between verbal ability and numerical ability on the ability to solve linear equation system problems with a value of Fhitung = 3,660 > Ftabel = 3,39. The magnitude of this influence is written in the form of a regression equation, namely Y = 24,602 + 0,140X1 + 0,224X2. This regression equation shows that if the verbal ability score increases by 1 with a fixed numerical ability score, then the ability to solve math problems will increase by 0,140; and if the numerical ability score increases by 1 with a fixed verbal ability score, the value of the ability to solve story questions will increase by 0,225 and plus 24,602 from other factors.
