Penelitian ini adalah penelitian kualitatif deskriptif yang bertujuan untuk mendeskripsikan kemampuan pemecahan masalah siswa kelas XI SMA dalam menyelesaikan soal-soal pemecahan masalah matematika pada pokok bahasan lingkaran. Subjek dalam penelitian ini adalah 30 siswa di salah satu kelas XI IPA di SMA Negeri 5 Kota Bengkulu yang dipilih secara purposive sampling. Setelah siswa mengerjakan 5 soal pemecahan masalah tentang lingkaran selama 60 menit secara tertulis, jawaban siswa kemudian dianalisis dan diidentifikasi untuk menemukan bagaimana siswa menyelesaikan soal, banyak strategi pemecahan masalah yang digunakan siswa, serta banyak solusi atau jawaban yang didapat. Hasil penelitian menunjukkan bahwa beberapa siswa belum mampu menyelesaikan masalah dengan tepat disebabkan kesalahan dalam langkah mensintesis dan menganalisis soal. Strategi yang mayoritas digunakan oleh para siswa dalam menyelesaikan masalah adalah drawing a picture (menggambar). Siswa juga menggunakan strategi guessing and checking (menebak dan menguji). Berkaitan dengan banyaknya jawaban siswa, siswa menjawab soal tertutup dengan jawaban yang sama, sedangkan untuk soal terbuka ditemukan tiga jawaban berbeda.Students’ problem-solving ability in solving closed and open-ended problems on the subject of the circleAbstractThis research was descriptive qualitative research that aimed to describe the problem-solving abilities of eleventh-grade students in solving mathematical problems on the subject of the circle. The subjects in this study were 30 students in one of the XI Science classes in SMA Negeri 5 Bengkulu City, Indonesia selected by purposive sampling. After students worked on five problem-solving questions about the circle for 60 minutes in writing-form, the students’ answers were then analyzed and identified to find how students solve the problems, how many problem-solving strategies used by students as well as many solutions or answers obtained. The research finding showed that some students have been not able to solve the problems correctly due to their misconceptions when doing the steps of synthesizing and analyzing. The majority of the strategies used by students in solving problems were drawing a picture. Students also used the guessing and checking strategy. Regarding the number of students' answers found, students answered closed questions with the same answers while for open-ended questions, it was found that students were able to find three different answers.

This study aims to obtain an overview of the characteristics and levels of metacognitive ability of junior high school students as seen from the melancholic and choleric personality types according to Hippocrates-Galenus. The results of this study are expected to be used as consideration for teachers in designing mathematics lessons that pay attention to personality types and students' metacognitive processes. A qualitative descriptive approach was chosen to answer the research objectives. At the same time, the research subjects were two grade VII students with melancholic and choleric personality types in one of the Muhammadiyah Junior High Schools in Jepara. The purposive sampling technique used in this research to subject selection. Data collection techniques used personality type questionnaires, metacognition tests, and interviews. Data analysis used three steps, namely data reduction, data presentation and conclusion drawing. The results showed that melancholic and choleric students had different characteristics and levels of metacognition. Melancholic students are at the metacognitive level between tacit use and aware use, while the rest of the cholerics are at the tacit use metacognition level. Penelitian ini bertujuan untuk mendapatkan gambaran tentang karakteristik dan jenjang kemampuan metakognisi siswa SMP yang dilihat dari tipe kepribadian melankolis dan koleris menurut Hippocrates-Galenus. Hasil penelitian ini diharapkan dapat dijadikan sebagai bahan pertimbangan guru dalam mendesain pembelajaran matematika yang memperhatikan tipe kepribadian dan proses metakognisi siswa. Pendekatan deskriptif kualitatif dipilih untuk menjawab tujuan penelitian. Sedangkan subjek penelitian adalah dua orang siswa kelas VII yang bertipe kepribadian melankolis dan koleris di salah satu SMP Muhammadiyah di Jepara. Adapun teknik pemilihan subjek penelitian menggunakan teknik purposive sampling. Teknik pengumpulan data menggunakan angket tipe kepribadian, tes metakognisi, dan wawancara.

ABSTRACT Metacognition is one of the important things in supporting one's success in solving mathematics problems because by using metacognition when solving problems, effective problem solving will be obtained. Metacognition is one's awareness of his own thought process. In dealing with a problem, it will be influenced by Adversity Quotient (AQ), namely intelligence in facing difficulties and changing barriers into opportunities for success. This research is a qualitative descriptive study. The subjects in this study were a Satya Wacana Christian University Mathematics Education student who had the AQ type of quitters. Quitters are a type of human who easily gives up in the face of difficulties. The results showed that the metacognition process experienced by the subject included metacognition awareness, evaluation, and regulation. In addition, metacognition also helps the subject to make thoughts and problem solving strategies more effective.
