Abstract

The sets concept that still be the problems for students of class VII at SMPN 15 Mataram. The average of daily test score on the material sets of students of class VII is 60.45 with 38.81% of classical completeness. It means that most of seventh grade students make mistakes in order to complete the daily test questions related to the concept of the sets. The aim of this research is to identify an error to solve the question of sets by students of seventh grade at SMPN 15 Mataram in academic year 2017/2018. In addition, this study is conducted to determine the level of error to solve about the sets material, and to see the relationship of every types of error with the overall error in order to solve the question of sets. The type of this research is descriptive research of quantitative type. The data analysis technique used in this research is statistical descriptive data analysis and correlation analysis of pearson product moment test. The result of the research shows that the dominant error of students is the type of error using theorem, definition, or formula with error percentage 56.19%. Based on the basic competence of the sets material, students make the most mistake on basic competence 4.5 with percentage of error of 61.71%. In addition, the type of error using the data is stronger relation with a correlation coefficient 0.89 which is very strong category.

Abstract

The formulation of the problem in this research is to find out how difficult it is to understand students' concepts in the material of flat-sided geometry in terms of metacognition skills in class VIII A students of SMPN 3 Narmada for the 2020/2021 academic year. This study aims to describe the difficulty of understanding concepts in the flat-sided geometrical material in terms of the metacognitive skills of class VIII A students for the 2020/2021 academic year. This research uses descriptive qualitative research. The subjects of this study were students of class VIII A as many as 33 students. Data collection in this study was carried out using research instruments in the form of questionnaires, tests, and interviews. The results showed that students with high metacognitive skill category could fulfill all indicators of concept understanding. Students who have moderate metacognition skills can only fulfill two indicators of concept understanding, namely restating a concept, and applying the concept algorithmically. And students who have low metacognitive skills are only able to fulfill one indicator.

Abstract

Kemampuan memecahkan masalah merupakan salah satu keterampilan yang dibutuhkan sumber daya manusia sebagai tolak ukur pelatihan pola pikir. Selain itu, jika ada kemauan untuk belajar maka hasil belajar akan optimal. Semakin siswa termotivasi, semakin tinggi hasil belajar yang akan mereka capai. Kenyataannya, di SMAN 7 Mataram  prestasi masih kurang yang diduga diakibatkan oleh keterampilan pemecahan masalah yang rendah. Penelitian ini bertujuan untuk mengetahui pengaruh motivasi belajar siswa terhadap kemampuan pemecahan masalah matematika pada materi MIPA Kelas XI SMAN7 Mataram.  Penelitian Ini menggunakan jenis penelitian kuantitatif. Populasi penelitian ini adalah siswa kelas XIMIPA SMAN 7 Mataram yang menggunakan teknik purfosive sampling sebanyak 67 subjek yang terdiri dari dua kelas yaitu XI MIPA1 dan XI MIPA3. Teknik pengumpulan data adalah angket (kuisioner), soal tes, dan wawancara. Teknik analisis data yang digunakan adalah analisis regresi linier sederhana. Hasil penelitian menunjukkan bahwa hasil model persamaan regresi Ŷ = 25,130 + 0,598 X dan hasil perhitungan memberikan nilai = 12,133> 3,99 dan nilai = 3,483 >  = 1,999. Hal ini berpengaruh signifikan terhadap motivasi belajar siswa dalam memecahkan masalah matematika kelas XI MIPA SMAN 7 Mataram. Dari model regresi dapat ditegaskan bahwa untuk setiap kenaikan 1% nilai motivasi belajar maka nilai kemampuan bertambah 0,598 untuk menyelesaikan masalah. Selain itu, dilakukan analisis koefisien determinasi untuk mengetahui besarnya pengaruh motivasi belajar terhadap kemampuan pemecahan masalah matematika, dan kontribusi motivasi belajar terhadap kemampuan pemecahan masalah matematika yaitu sebesar 15,7%.

Abstract

This study aims to determine: 1) the types of errors of students of class VIII-6 of SMP in solving problems with the circle subject. 2) the factors that cause students of class VIII-6 of SMP to make mistakes in solving problems with the circle subject. This research is classified as descriptive quantitative research. The population in this study were all students of class VIII-6 SMP which consisted of seven classes. The sampling technique used was simple random sampling. The research subjects were students of class VIII-6 SMP as many as 28 students. The research procedure used in this research is written test and interview. The test was used to analyze reading errors, comprehension errors, transformation errors, processing skills error and encoding error. Meanwhile, interviews are used to trace students mistakes in depth. The instrument testing conducted was a content validity tester in consultation with experts, namely mathematics teachers and leacturers. The result showed that there were 5 types of error categories committed by students of SMP, namely: 1) reading errors of 13,94% were in the low error category. 2) comprehension error of 47,61% is in the sufficient error category. 3) transformation error of 57,53% is in the sufficient error category. 4) process skills error as much as 66,66% in the high error category. 5) encoding error of 94,39% in the very high error category..

Abstract

The purpose of this research was to describe the level and relationship of mathematical problem solving students based on the Adversity Quotient (AQ) level on year academic 2019/2020. The research metodology used was questionnaires, tests, and interviews. The results showed that the AQ level of 8th grade students was generally dominant at the moderate AQ level (camper), that is 23 students (71.88%) from 32 students who took the questionnaire. In solving mathematical problems according to the Polya stage, students who are at a high AQ level (climber) have moderate abilities at the stage of understand the problem, devise and carry out the plans to solve the problem, and having abilities with a low level at the stage of look back. Students at the moderate AQ level (campers) have moderate abilities at the stage of understand the problem, have good abilities at the stage of devise and carry out the plans to solve the problem, and have low levels of ability at the stage of look back. Students at a low AQ level (quitter) have moderate abilities at the stage of understand the problem, devise and carry out the plans to solve the problem, and having a low level ability at the stage of look back. Based on the Spearman rank, it was found that there was a relationship between the AQ level and the students' mathematical problem solving ability, but it was classified as very low and only had an effect of 1.21%. This is because the climbers have not been able to carry out all stages of Polya's problem solving well, the habits of students who only rely on memorizing formulas when facing math problems, and the habit of discussing when written tests take place which makes students unable to focus optimally in solving problems.

Abstract

The problem of scheduling learning activities at SMKN 4 Mataram is the same teachers are scheduled at the same time in two class or more. The coloring graph concept can be used to find out the causes of the scheduling problems at SMKN 4 Mataram. Based on result of the application coloring graph concept generated to the chromatic number is 23 with slots number is 46 which is smaller than 55 or time slots at SMKN 4 Mataram. Because slots of chromatic number are smaller than the time slots at SMKN 4 Mataram, it is known that the causes of scheduling problems at SMKN 4 Mataram are wrong scheduling way. One of solution to this problem is to compile a schedule based on the coloring graph concept by mapping 419 subjects with 84 teachers and 55 time slots spread from Monday to Saturday. In applying the coloring graph concept, the Largest Degree Ordering (LDO) algorithm is used. It is because this algorithm is simpler than other algorithms.
