Abstract

Metacognition is the students awareness about their thought processes and monitoring their thought processes. One of thought processes which referred is problem solving ability. In problem-solving the students were different levels of metacognition. Level of metacognition consists of tacit use, aware use, strategic use, dan reflektive use. The purpose of this study was to determine the level of metacognition of students in solving problems and the relationship between mathematical problem solving abilities and the level of metacognition. The research was conducted by giving test instruments to 23 sample students. This research was a descriptive research with qualitative and quantitative approaches. Qualitative data analysis used flow models method with the stages of data reduction, data presentation and drawing conclusions. Furthermore, quantitative data analysis used spearman rank correlation. After the data analysis process, the results of the research were metacognition level of class IX students consisting of tacit use, aware use, and strategic use with percentages of 80%, 15%, and 5%. Furthermore, relationship between problem solving ability and the level of metacognition are in the very high category with a correlation coefficient of 0.68. Therefore, when the problem-solving ability increases, the level of metacognition also increases.

Abstract

This research aims to describe the profile of implementation mathematics learning and sociomatematic norms in collaborative learning of algebraic material topic at VII-C SMPN 13 Mataram in the 2019/2020 academic year. Indicators of sociomathematic norms in this research are based on the ability to communicate mathematics and the social skills students in collaborative learning. The kind of research this is descriptive qualitative with instruments of data collection which used are the learning device which includes RPP, LLPD, observation sheet of sociomathematic norms in collaboration activities and interview guidelines. The subjects in this study were 30 students who had a category of positive belief in collaborative activities. There are 3 categories of positive belief, namely P1, P2 and P3. P1 subject has a positive belief in collaborative activities and has the ability to solve problems independently, many as 0 people. P2 subjects who have positive beliefs about the effectiveness of collaboration and have the ability to solve problems independently but sometimes need the help of a friend or teacher, many as 28 people. P3 subjects who have positive belief in collaborative activities and do not have the ability to solve problems independently or always need the help of a friend or teacher, many as 2 people. The research subjects had an average percentage of sociomatematic norms ˃ 56%, this means that these subjects had good mathematical communication skills and social skills.

Abstract

This study aimed to describe the mathematical problem solving ability of class VIII MTsN 1 Mataram at academic year 2019/2020 in solving numbers pattern problems based on reflective and impulsive cognitive styles. This type of research was quantitative descriptive research. The subjects in this study were students of class VIII-6 MTsN 1 Mataram at academic year 2019/2020. Data retrieval were done by using the cognitive test and the test results of problem solving. Based on the results of the study, it was found that the number of reflective students were 14 students (63,6%) who were distributed into 5 students (22,7%) with high ability, 7 students (31,8%) with moderate ability, and 2 student (9,1%) with low ability. While the number of impulsive students were 8 students who distributed into 5 students (22,7%) with medium ability and 3 students (13,6%) with low ability. Those results showed that there were differences in problem solving abilities between students who had reflective and impulsive cognitive styles. Reflective students in solving problems had been able to meet all the indicators at the problem solving stage according to Polya namely understanding the problem, thinking about the plan, carrying out the plan, and looking back. While impulsive students in solving problems had been able to fulfill the indicators thinking about plans and implementing plans. Impulsive students tend to skip the stages of understanding a problem and looking back.

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

The purpose of this research is to produce a learning audiovisual media that is suitable for the material of build a flat side room in SMP Negeri 6 Mataram. The method used in this research is according to Luther, is multimedia development life cycle (MDLC). MDLC have 6 steps, there are concept, design, material collecting, assembly, testing, and distribution. Field testing was used in this research are validation test, practical test, and test for the learning media’s effectiveness. In validation test, the result of this research is validated by some experts. The practical test was carried out by 2 practitioners and the test for effectiveness was based on the results of the questionnaire which were filled in by 74 students (37 students of class VIII and 37 students of grade IX). Instrumen indicators are based on the feasibility of the media according to Thorn. The results of the validation test showed an average score of 3.14, with a very good category. Meanwhile, the results of the practical test with an average score are 3.39 in the very good category, and the results of the effectiveness test with an average score of 2.86 in the good category. So it can be concluded that the audiovisual learning media that have been developed are suitable for use in learning mathematics.

Abstract

When visiting several tourist attractions at once with limited time and an irregular schedule, of course, visitors choose the closest route to be able to visit all the places to be visited at once. This study uses an algorithm, namely the Kruskal algorithm, which aims to find the closest route to visit the five tourist attractions at once in Central Lombok Regency. The tourist attractions in question are Tanjung Aan Beach, Kuta Mandalika Beach, Sukarara Village, Sade Hamlet, Benang Kelambu Waterfall. This type of research is applied research which is generally a type of descriptive research that encourages further research. This study applies a modified Kruskal algorithm so as to produce 4 alternative closest routes with different starting points to be able to visit the five tourist attractions at once in Central Lombok Regency, namely 1) If the journey starts from Tanjung Aan Beach or Benang Kelambu Waterfall, the closest route is 60,1 km; 2) If the journey starts from Kuta Mandalika Beach, the closest route is 73.6 km; 3) If the journey starts from Sade Hamlet, the closest route is 73.6 km; 4) If the journey starts from Sukarara Village, the closest route is 82.9 km
