“…Kemampuan pemecahan masalah sangat penting dan harus dimiliki oleh setiap siswa (Lestari & Rosdiana, 2018;Lusiana, Armiati, & Yerizon, 2022). Hal ini diperlukan untuk melatih siswa agar terbiasa menghadapi berbagai macam permasalahan yang ada, baik permasalahan dalam matematika, masalah dalam bidang studi lainnya, ataupun permasalahan yang ditemui pada kehidupan sehari-hari yang semakin kompleks (Gradini, Yustinaningrum, & Safitri, 2022). Apalagi di zaman modern ini, ilmu pengetahuan dan teknologi terus berkembang pesat (Firnanda & Pratama, 2020;Damayanti & Kartini, 2022).…”

Problem-solving skills are very important and must be possessed by all students. This is necessary to train students to get used to solving various problems. Problem-solving in the form of story questions needs serious attention because story questions provide a real picture of various life problems using mathematical sentences. The purpose of this study was to determine the problem-solving ability of junior high school students in solving story problems on the Quadratic Equations Material. This type of research is descriptive qualitative research. The technique of taking subject of this study used a purposive sampling technique. The subjects of this study were five grade IX junior high school students in Kutawaringin Village. Data collection techniques used are tests, interviews, and field notes. Data analysis techniques are data reduction, presentation, and conclusions. From the results of the study, it can be concluded that junior high school students have not been able to solve story problems on the Quadratic Equation material because students have not been able to apply all the indicators of problem-solving. This is because students are less careful in arithmetic operations which results in many errors. In addition, because students do not understand the concepts in the questions, so they cannot solve problems completely and most importantly, students are not familiar with non-routine questions.Kemampuan pemecahan masalah sangat penting dan harus dimiliki oleh semua siswa. Hal ini diperlukan untuk melatih siswa agar terbiasa memecahkan berbagai masalah. Pemecahan masalah dalam bentuk soal cerita perlu mendapat perhatian serius, karena soal cerita memberikan gambaran nyata tentang berbagai masalah kehidupan dengan menggunakan kalimat matematika. Tujuan penelitian ini adalah untuk mengetahui kemampuan pemecahan masalah siswa SMP dalam menyelesaikan soal cerita pada materi Persamaan Kuadrat. Jenis penelitian ini adalah penelitian kualitatif deskriptif. Teknik pengambilan subjek penelitian ini menggunakan teknik purposive sampling. Subjek dari penelitian ini adalah lima siswa SMP kelas IX di Desa Kutawaringin. Teknik pengumpulan data yang digunakan yaitu tes, wawancara, dan catatan lapangan. Teknik analisis data yang digunakan yaitu reduksi data, penyajian data, dan penarikan kesimpulan. Dari hasil penelitian dapat disimpulkan bahwa siswa SMP belum mampu memecahkan soal cerita pada materi Persamaan Kuadrat karena siswa belum mampu menerapkan seluruh indikator dari pemecahan masalah. Hal ini disebabkan karena siswa kurang teliti dalam operasi hitung yang mengakibatkan banyak terjadi kesalahan. Selain itu, karena siswa belum memahami konsep pada soal, sehingga belum bisa memecahkan masalah dengan tuntas dan yang paling utama adalah siswa tidak terbiasa dengan soal-soal non-rutin.

“…Persamaan Trigonometri merupakan materi yang dipelajari dalam mata pelajaran matematika, persamaan trigonometri ini dapat bermanfaat dalam kehidupan sehari-hari (Gradini, Yustinaningrum, & Safitri, 2022). Dengan aplikasi trigonometri kita bisa mengukur jarak suatu bintang di langit tanpa kita harus mengukurnya menggunakan alat ukur nyata (Taufiq & Agustito, 2021;Laja, 2022).…”

Many factors cause the low learning ability of students in mathematics. The purpose of this study was to analyze students' difficulties in solving problems on the material of Trigonometric Equations. The type of research used is qualitative research. This research was conducted in the village of Pasanggrahan, Garut. The research subjects were four high school students of class XI who were taken randomly. The data collection techniques in this study were observation, tests, interviews, and documentation. The instruments used were test question sheets and interview guidelines. The results of this study indicate that students have difficulty in solving a basic trigonometric equation, difficulty in modeling problems related to trigonometric equations, and difficulty in determining a trigonometric equation and the set of solutions.

“…Trigonometry comparisons are classified as the most difficult material for students (Cholid et al, 2022). Based on the results of previous research by Gradini, et al (2022) it was found that students' mistakes in solving Trigonometry problems were: (i) Misunderstanding of Trigonometry problems (57.73%); (ii) Errors in preparing settlement plans (9.27%); (iii) Failure to implement the settlement plan (15.83%); and (iv) Errors in re-examining (17.16%). Based on these problems, research on the analysis of student errors in solving trigonometry comparison questions is very important to do.…”

“…(Polya, 1973: 5) states that solving mathematical problems consists of four steps, namely (1) understanding the problem, (2) devising a plan, (3) implementing the plan, and (4) re-checking the answers. The Polya criterion emphasizes a mindset in solving problems mathematically (Gradini et al, 2022).…”

Student mistakes in solving trigonometry problems have an impact on low student learning outcomes. This study aims to determine the percentage of student errors in solving trigonometry problems and describe the causes of these errors based on the Polya Criteria guidelines. This research is descriptive qualitative type. The subjects of this study were 35 students of class X.J SMA N 1 Wonosari. Data collection techniques used in this study were tests and interviews. The validity of the data is based on the triangulation process. Data analysis techniques in this study use data reduction techniques, data presentation, and drawing conclusions. Based on the results and discussion, it can be concluded that the students' mistakes in solving trigonometry problems with the Polya Criteria guide are as follows: 1) Understanding the problem (12.99%), 2) Developing a solution plan (30.30%), 3) Implementing a settlement plan (26.19%), 4) Checking again (30.52%). The causes of these errors, namely: students cannot understand the purpose of the questions given, students rarely solve problems by knowing, asking, answering, and concluding, students are confused about applying the trigonometry formula to solve problems, students are hasty and careless in solving problems, students are not used to it and feel no need to write conclusions at the end of the answer.Keywords: error, trigonometry, polya criteria
