This study aims to analyze students 'mathematical problem-solving abilities in solving the problem of build space and knowing students' opinions on mathematics. The study was conducted on grade VII students at one of SMPN in Cimahi. The research approach used is qualitative with descriptive method. Instruments have been validated and consist of problem-solving test, interview guides, and questionnaires. The test that students do is given a score and an analysis of error answers. Questionnaires are used to obtain information about students' opinions in solving problems. The results showed that as many as 5 students made comprehensions error, as many as 13 students made transformation error, as many as 29 students made process skill error, and as many as 33 students made encoding error, so it can be concluded that the problem-solving ability of students in one of SMPN in Cimahi is still low so it is necessary to do improvement effort. However, students have a positive opinion on mathematics with an average of 69.41%.

Penelitian ini bertujuan untuk menganalisis kemampuan mathematical problem posing siswa SMK antara yang menggunakan pendekatan open-ended dan pendekatan saintifik. Populasi penelitian adalah siswa SMK kelas XI di SMK TI Pembangunan Kota Cimahi, Jawa Barat. Sampel diperoleh dengan teknik purposive sampling, yaitu dua kelas dengan kemampuan matematis siswa yang tidak berbeda secara signifikan, sehingga diperoleh dua kelas yaitu XI RPL-B sebagai kelas eksperimen yang menggunakan pendekatan open-ended dan XI TEI-C sebagai kelas kontrol yang menggunakan pendekatan saintifik. Kedua kelas memiliki kemampuan matematis yang tidak berbeda secara signifikan melalui uji-t. Metode penelitian menggunakan kuasi eksperimen. Instrumen yang digunakan berupa tes kemampuan mathematical problem posing yang berjumlah lima butir soal uraian pada materi persamaan kuadrat. Teknik analisis data menggunakan uji statistic independent sample t-test terhadap hasil data pretest dan posttest kelas eksperimen dan kelas kontrol melalui uji normalitas, dan uji nonparametrik Mann-Whitney. Hasil penelitian menunjukkan bahwa kemampuan mathematical problem posing siswa menggunakan pendekatan open-ended lebih baik daripada menggunakan pendekatan saintifik. Pendekatan open-ended memberikan siswa kesempatan yang lebih banyak dalam mengeksplorasi aktivitas menyusun masalah baru atau membuat pertanyaan berdasarkan informasi yang tersedia, sehingga jawaban siswa menjadi lebih beraneka ragam.

ABSTRAK. Kemampuan berpikir kritis sangat penting dilatih dan dikembangkan pada siswa. Salah satu aspek dari berpikir kritis adalah memeriksa kecukupan data pada masalah matematika. Keyakinan diri atau self-efficacy dalam matematika juga perlu dimiliki siswa untuk memperoleh jawaban yang tepat. Penelitian ini bertujuan untuk mengetahui kemampuan siswa dalam mengidentifikasi kecukupan data terhadap soal sistem persamaan linear dua variabel dan self-efficacy mereka terhadap matematika. Pendekatan penelitian yang digunakan adalah kualitatif dengan metode deskriptif untuk memperoleh gambaran sebenarnya terhadap kemampuan siswa ketika menjawab soal dan self-efficacy yang dimiliki siswa setelah menjawab soal. Instrumen yang digunakan adalah tes, skala self-efficacy, dan pedoman wawancara. Hasil penelitian ini menyatakan bahwa kemampuan siswa dalam mengidentifikasi kecukupan data pada soal sistem persamaan linear dua variabel masih rendah, lebih dari setengah siswa memperoleh skor dengan kriteria tidak baik. Siswa kesulitan menjawab soal karena tidak terbiasa mengerjakan soal, tidak fokus pada pertanyaan, dan kemampuan operasi pembagian yang tidak baik sehingga banyak memperoleh hasil yang tidak tepat. Siswa memiliki keyakinan diri yang baik. Sebagian besar siswa setuju terhadap semua aspek self-efficacy. Tidak terdapat hubungan yang signifikan antara skor tes dengan self-efficacy siswa. Hubungan yang terjadi berlawanan arah, skor tes yang rendah tidak menyebabkan keyakinan diri siswa menjadi tidak baik.Â Kata Kunci: Kemampuan Berpikir Kritis, Mengidentifikasi Kecukupan Data pada Masalah Matematika, Self-Efficacy.

The purpose of this study is to determine the improvement of students' mathematical representation ability after applying the Problem Based Learning (PBL) Model in junior high school students. The research method used is a quasi-experimental research with a Control Group Pretest-Posttest Design. The sample of this study consisted of 30 students in the experimental class and 30 in the control class. The sample in this study was taken by simple random sampling. Data collection was used using a mathematical representation ability test sheet. The data analysis techniques used are the N-Gain test, and the independent t-test. The results of the study were obtained: (1) The application of the PBL model can improve the ability of mathematical representation with an average N-Gain value of 0.43 which is classified as "moderate", (2) Based on the independent t-test, obtained 0.000, it can be concluded that the mathematical representation ability of students who are taught the PBL model is better than the mathematical representation ability of students who are taught with regular learning.
