Mathematical representation skill is students' ability to express mathematical ideas (such as problems, statements, and definitions) in various ways to solve problems through multiple representations, such as images, words, tables, and symbols mathematics. Students are struggling in representing mathematical ideas. It hampers them in determining the solution of mathematical problems. They are careless in reading the word problems, lacking problem analysis, less thorough, and struggling to connect concepts. The subjects of this study were in two students from one of the junior high school in Jambi. The instruments used for this research were VVQ, Mathematical Representation Ability Test and interviews. This study used a descriptive qualitative method. The results showed that the representation abilities of students with visualizer and verbalizer style were quite good. However, each subject had a different way of solving problems. Visualizers were more interested in questions with image information in solving the problem. Verbalizer tended to prefer information with detailed wording.

The purpose of this study is to describe the intuition characteristics of junior high school students in solving mathematical problems viewed from mathematical abilities. This research based on qualitative descriptive study. The subjects of this study were taken from Lab School UNESA  Junior High School, which consisted of three students from class VIII A, namely one student with high, moderate,  and low mathematical ability. The method that used to collect data consists of the mathematical ability test,  problem solving test and so of the interview method. Data analysis uses the intuitive characteristic indicators at each stage of the problem solving. The conclusion of this study indicate that student with high mathematical ability at the stage of understanding the problem using affirmatory intuition with the characteristics of extrapolativeness, intrinsic certainty and perseverance, at the stage of making plans using anticipatory intuition with the characteristics of global ideas, and at the stage of carrying out plans and checking again not using intuition. Student with moderate mathematical ability at the stage of understanding the problem using affirmatory intuition with the characteristics of extrapolativeness, intrinsic certainty and perseverance, at the stage of making plans using anticipatory intuition with the characteristics of global ideas, and at the stage of carrying out plans and checking again not using intuition. Student with low mathematical ability at the stage of understanding the problem using affirmatory intuition with the characteristics of perseverance and coerciveness, at the stage of making plans using anticipatory intuition with the characteristics of global ideas, and at the stage of carrying out plans and checking again not using intuition. Keywords: Intuition, Problem solving , Mathematics ability

Penalaran adaptif merupakan salah satu keterampilan matematika yang perlu dikuasai siswa dalam pembelajaran di sekolah. Jika siswa memiliki penalaran adaptif yang baik, maka siswa lebih mudah dalam memecahkan masalah matematika. Dalam memecahkan masalah matematika, setiap siswa mempunyai respon yang berbeda-beda. Respon tersebut dinamakan Adversity Quotient (AQ). Penelitian ini bertujuan untuk mendeskripsikan penalaran adaptif siswa dalam memecahkan masalah matematika berdasarkan AQ. Jenis penelitian ini adalah deskriptif kualitatif dengan subjek penelitian sebanyak enam siswa. Metode pengumpulan data yang digunakan meliputi pemberian angket ARP (Adversity Response Profile) untuk mengelompokkan siswa berdasarkan tipe AQ, tes penalaran adaptif (TPA) untuk mengetahui penalaran adaptif siswa dalam memecahkan masalah matematika dan wawancara untuk memperoleh informasi yang lebih jelas terkait penalaran adaptif siswa. Adapun proses analisis data yang digunakan meliputi reduksi data, penyajian data dan  penarikan kesimpulan. Hasil penelitian menunjukkan bahwa dalam memecahkan masalah matematika, siswa dengan AQ quitter hanya mampu memenuhi satu indikator penalaran adaptif yaitu menyusun dugaan. Siswa dengan AQ camper mampu memenuhi empat indikator penalaran adaptif yaitu menyusun dugaan, merencanakan dan menyelesaikan masalah matematika, menilai kebenaran jawaban dari suatu permasalahan serta memberikan jawaban dengan penarikan kesimpulan. Sedangkan siswa dengan AQ climber mampu memenuhi semua indikator penalaran adaptif, yaitu menyusun dugaan, merencanakan dan menyelesaikan masalah matematika, memberikan penjelasan terkait prosedur yang digunakan, menilai kebenaran jawaban dari suatu permasalahan serta memberikan jawaban dengan penarikan kesimpulan.     Mathematical problems that they must solve. This is because mathematical representation is a form of expression of ideas displayed by students in various forms in certain situations in an effort to find solutions to the problems faced. The lack of students' understanding of the questions given is most likely due to students who are not able to use mathematical representation correctly. This research is a descriptive study with a qualitative approach that aims to describe the mathematical representation of junior high school students, especially students with high ability in solving math problems. The subject of this research is one of the eighth grade students of SMP 10 November Sidoarjo selected based on a mathematical ability test. The results of the data description show that in solving problems, students with high mathematical abilities tend to use visual representations, make mathematical equations or mathematical expressions, and answer problems by using written words or text with the results of solving problems mostly correct.

Abstrak Representasi matematis digunakan siswa ketika menghadapi soal matematika yang harus mereka selesaikan. Hal ini karena representasi matematis merupakan bentuk ungkapan ide yang ditampilkan siswa dalam bentuk yang beragam dalam situasi tertentu sebagai upaya menemukan solusi dari soal yang dihadapi. Rendahnya pemahaman siswa terhadap soal yang diberikan kemungkinan besar disebabkan oleh siswa yang tidak mampu menggunakan reprentasi matematis dengan benar. Penelitian ini merupakan penelitian deskriptif dengan pendekatan kualitatif yang bertujuan untuk mendeskripsikan representasi matematis siswa SMP, khususnya siswa berkemampuan tinggi dalam menyelesaikan soal matematika. Subjek penelitian ini merupakan salah satu siswa kelas VIII SMP 10 Nopember Sidoarjo yang dipilih berdasarkan tes kemampuan matematis. Hasil deskripsi data menunjukkan bahwa dalam menyelesaikan soal, siswa berkemampuan matematika tinggi cenderung menggunakan representasi visual untuk menyelesaikan masalah, membuat persamaan matematis atau ekspresi matematis, serta menjawab permasalahan dengan menggunakan kata-kata atau teks tertulis dengan hasil penyelesaian soal sebagian besar benar.   Abstract Mathematical problems that they must solve.
