Abstract

This study aims to describe the level of students' ability in solving High Order Thinking Skills (HOTS) math problems based on the Polya step in the number pattern material for class VIII SMPN 2 Praya in the 2021/2022 academic year. The type of research used is descriptive qualitative research. The research subjects were 30 students who were selected with a sampling technique using purposive sampling. The data collection techniques using tests and interviews. The data analysis technique was carried out using the data reduction stage, the data presentation stage, and the conclusion drawing stage. The results of the students study with a highly capable of meeting each step of rhe Polya, students with the ability has not been able to meet the fourth stage of reexamining the results obtained, and the students with enough ability is not able to meet the phase of implementing the plan and reexamining the results obtained. Whereas, students with the less abilitiy were not able to make a plan, implement a plan and reexamine the results obtained and greatly less ability were unable to fulfill all of the Polya steps. Overall, the average students ability to solve the mathematics problem of HOTS by Polya measures fall below the category. The majority of students do not write down what is known and asked for, struggle to make plans and carry out plans, miscalculate calculation, and do not know how to reexamine the results.

Abstract

The purpose of this study was to describe the level of mathematical literacy ability of class VIII MTsN 1 Mataram based on gender. The research is quantitative desciptive research which method are used to describe, explain various variabel in the study as expressed the documentary materials. The assessment system in this study uses 2 methods, namely mathematical literacy and analytical problem solving. Mathematical literacy has 6 (six) levels in measurement and consists of three aspects, namely content, context, and cognitive aspects, while for assessment using analytical problem solving there are 3 (three) levels, namely low, medium and high. The data collection technique used a questionnaire in the form of mathematical literacy test questions that had been approved by 3 validators. Based on the results of the research, the level of mathematical literacy skills, based on mathematical literacy female dominant at level 3 which means that students are able to apply the basic algorithm, formulate and carry out the procedure and can select and apply strategies to solve simple and the mathematical literacy skills of male students are dominant at level 2 which means that students are able to apply the basic algorithm, formulate and carry out the procedure. Based on analytical problem solving students' mathematical literacy skills are at low and medium levels where female mathematical literacy skills are higher compared to male. Bassed t-test 2 sampel independent mathematical literacy ability male and female doesn’t have a significant difference.

Abstract

This study aims to determine the percentage of each type of student error based on student achievement and the relationship between types of errors in solving trigonometric problems with overall errors. This research is a descriptive correlational research. The sample used in this study was 15% of all students in class XI MAN 1 Central Lombok in the 2019/2020 academic year including 8 low achieving students, 29 medium achieving students, and 5 high achieving students. The data in this study came from student test results. The test results data were analyzed to find out how big the percentage of errors made by students and how big the level of error relationship was based on the object of mathematical study which included factual errors, conceptual errors, operating errors and principle errors with overall errors. The results showed that the students of class XI MAN 1 Central Lombok had a percentage of errors based on student achievement, respectively, from high, medium and low achievers. Fact errors with percentages of 40%, 63% and 50%, respectively, are in the moderate category. Concept errors with percentages of 35%, 49% and 66%, respectively, are in the low category. Operational errors with percentages of 33%, 60% and 67%, respectively, are in the moderate category. Errors in principle with a percentage of 42%, 68% and 72%, respectively, are in the moderate category. The relationship between each error and the overall error is a factual error of 0.52 is moderate, a conceptual error of 0.85 is very strong, an operating error of 0.88 is very strong, and a principle error of 0.95 is very strong.

Abstract

This correlation study aims to describe students' perceptions in online learning, learning independence, and student achievement and to determine the relationship between student perceptions in online learning and learning independence and student achievement. The population is all eighth grade students at SMP Negeri 17 Mataram for the 2020/2021 academic year. The sampling technique used purposive sampling technique and the samples obtained were students of class VIIIC. The data collection technique uses a questionnaire on student perceptions in online learning, student learning independence questionnaire, documentation, and interviews. Data analysis technique using Pearson correlation test. The results of data analysis show that: (1) students' perceptions in online learning are mostly in the sufficient category, students' learning independence is mostly in the good category and student achievement is mostly in the bad category; (2) There is a relationship between students' perceptions and learning independence and includes a positive correlation. (3) There is a correlation between students' perceptions of online learning and student achievement, including a negative correlation; (4) there is a correlation between learning independence and student achievement including a negative correlation. For this reason, apart from perceptions, learning independence and learning achievement, it is also a good idea to look at the motivation, talent and interest in student learning.

Abstract

Riset ini membahas aplikasi teori fuzzy dalam bidang statistik yakni hipotesa yang memiliki pernyataan fuzzy. Statistik uji yang digunakan untuk menaganalisa data adalah pvalue fuzzy yang dibandingkan dengan tingkat signifikansi fuzzy. Aplikasi data diterapkan pada data covid-19 di Nusa tenggara Barat. Kesimpulan dari uji hipotesa fuzzy memberikan keputusan yang lebih rasional daripada uji hipotesa klasik. Jika hipotesa nol fuzzy tidak berlaku pada data sampel, maka hipotesa nol fuzzy ditolak sampai derajat tertentu;

Abstract

Salah satu mata cabang ilmu pengetahuan adalah matematika dan salah satu aspek kemampuan yang penting dalam matematika adalah kemampuan pemecahan masalah. Siswa memiliki perbedaan kemampuan dalam memecahkan masalah, dan salah satu faktor yang mempengaruhinya adalah kepribadian. Penelitian ini bertujuan untuk mendeskripsikan kemampuan pemecahan masalah matematika ditinjau dari tipe kepribadian Myers Briggs Type Indicator (MBTI) siswa kelas IX MTs Negeri 1 Mataram Tahun Ajaran 2022/2023. Pendekatan yang digunakan dalam penelitian ini adalah pendekatan kualitatif dengan teknik penentuan subjek penelitian yaitu purposive dan simple random sampling. Pengumpulan data menggunakan teknik kuesioner, tes dan wawancara. Hasil penelitian menunjukkan bahwa subjek artisan hanya mampu melaksakan 2 dari 4 tahapan pemecahan masalah, yaitu tahapan memahami masalah dan melaksanakan rencana penyelesaian. Subjek idealist sudah mampu melewati 3 dari 4 tahapan pemecahan masalah, yaitu tahapan memahami masalah, melaksanakan rencana penyelesaian dan meninjau kembali. Subjek guardian hanya mampu melewati 1 dari 4 tahapan pemecahan masalah, yaitu tahapan memahami masalah. Subjek rational sudah mampu melewati 3 dari 4 tahapan pemecahan masalah, yaitu tahapan memahami masalah, melaksanakan rencana penyelesaian dan meninjau kembali. Jadi, disimpulkan bahwa subjek berkepribadian idealist dan rational memiliki kemampuan pemecahan masalah yang lebih baik dari subjek berkepribadian artisan dan guardian.
