The main target of the current study is to explain the metacognition of junior high school students with Field Independent (FI) and Field Dependent (FD) cognitive styles in mathematics problem-solving. It should be noted that the statistical population of this study was all junior high school students in the Sragen regency in the 2018/2019 academic year. To reach the research purpose, different instruments such as the cognitive style tests, the problem-solving exercises, and the interview guidance were used. Data analysis was carried out by data collection, data reduction, data presentation, and conclusion. The results indicated that the students who have field-independent cognitive style had high self-confidence that they were able to solve the problem correctly, able to do planning steps, able to make important decisions for themselves, so they can solve the problem properly. Students with FD cognitive style are completely confident that their answer is correct, but they have not yet clarified the steps they need to solve their problems and have not yet focused on their shortcomings in mathematics problem solving, so their task results in mathematics problem-solving incorrectness answer.   Keywords: Cognitive style; Mathematics problem solving; Metacognition

Penelitian ini bertujuan untuk mendeskripsikan kemampuan pemecahan masalah matematika, self-efficacy siswa dan hubungan antara kemampuan pemecahan masalah dan self-efficacy siswa kelas VIII SMP Negeri di Kabupaten Ciamis. Penelitian ini adalah penelitian survei. Subjek penelitian terdiri dari 389 siswa kelas VIII SMP Negeri di Kabupaten Ciamis yang berasal dari 13 sekolah dengan kategori strata tinggi, sedang dan rendah. Sampel dalam penelitian ini ditentukan dengan stratified proporsional random sampling. Hasil penelitian menunjukkan bahwa 389 siswa yang dijadikan subjek penelitian memiliki kemampuan pemecahan masalah dalam kriteria rendah. Faktor-faktor yang menyebabkan keadaan tersebut diantaranya adalah siswa kurang memahami informasi pada soal, siswa kurang mampu membuat model matematis, dan siswa kurang teliti dalam menyelesiakan soal. Rata-rata self-efficacy siswa berada pada kriteria sedang, yaitu 91,17. Hubungan kemampuan pemecahan masalah matematika dan self-efficacy siswa termasuk kategori sangat rendah karena nilai r sebesar 0,104. An Analysis of Mathematics Problem Solving Ability and Self-Efficacy Students of Junior High School in Ciamis Regency AbstractThis study aims to describe the mathematics problem-solving ability, self-efficacy of students and the relationship between the problem solving and self-efficacy of the grade VIII students of the junior high school in Ciamis Regency. This study was categorized as survey research. The research subjects were 389 junior high school grade VIII in Ciamis Regency from 13 schools which were categorized as high, moderate and low schools. The research sample was selected by means of the stratified proportional random sampling technique. The results of the study are as follows, 389 students as the research subject have low criteria in problem-solving ability. Factors that cause this situation, such as students are less understanding of existing information on the problem, students are less able to make mathematical models, and students are less thorough in problem-solving. The average of students’ self-efficacy was at moderate criteria, 91.17. The relationship between problem-solving ability and self-efficacy of students was at very low criteria because of the r-value of 0.104.

This study aims to determine the effect of students' mathematical dispositions on mathematical problem solving abilities of students in class VII of SMP. The type of research used is quantitative. The sample in this study was class VII A, amounting to 30 people who were selected using simple random sampling from 6 existing classes. The type of data in this research is primary data with data collection used using a disposition questionnaire consisting of 28 items and tests consisting of 5 items of description. Testing the hypothesis in this study using a simple regression test. After the data is analyzed the regression equation is obtained as follows: Y = 16,312 + 0.523X. before testing the hypothesis, the data normality test and linearity test were carried out. Based on the data analysis, it was found that the t-test = 3.296 with significance = 0.003 and table = 2.048. then t count = 3.296> 2.048 = t table means that data is normally distributed. To see the achievement of the disposition indicators of junior high school students in the junior high school class, the average of each indicator is calculated and the achievement of the mathematical disposition indicator is 50.08%. Whereas for grouping mathematical dispositions, problem solving abilities obtained the highest dispositions having an average of 63.04, moderate dispositions having an average of 43.56, and low dispositions having an average of 40.51. Thus, it can be concluded that there is an influence of mathematical disposition on mathematical problem solving abilities of students of junior high school class.
