This research is motivated by the many mistakes made by students in solving story problems. The purpose of this study was to find out the mistakes made by students in solving story problems on Trigonometry material and to find out the causes of errors made by students in working on story problems on Trigonometry material. This research method uses a descriptive method with a qualitative approach. The subjects of this study were students of class X IPS SMA PGRI 3 Padang in the 2020/2021 academic year who had been selected by total sampling. Instruments used for data collection in the form of tests, interviews, and documentation. The test results were analyzed based on the error according to Newman. The results showed that some students made mistakes in understanding, errors in transforming, errors in processing skills, errors in writing the final answer. The cause of this error is that students do not know what is actually being asked in the problem, and accidentally get information on the question, so they cannot complete the information for the next step, do not understand how it turns into a question. mathematical models, and not proficient in counting.

Penelitian ini dilatarbelakangi dengan banyaknya kesalahan yang dilakukan peserta didik dalam menyelesaikan soal cerita. Tujuan penelitian ini untuk mengetahui kesalahan yang dilakukan siswa dalam menyelesaikan soal cerita pada materi Trigonometri dan mengetahui penyebab terjadinya kesalahan yang dilakukan oleh siswa dalam mengerjakan soal cerita pada materi Trigonometri. Metode penelitian ini menggunakan metode deskriptif dengan pendekatan kualitatif. Subjek penelitian ini siswa kelas X IPS SMA PGRI 3 Padang Tahun Ajaran 2020/2021 yang telah dipilih secara total sampling. Instrument yang digunakan untuk pengumpulan data berupa tes, wawancara, dan dokumentasi. Hasil tes dianalisis berdasarkan kesalahan menurut Newman. Hasil penelitian menunjukkan sebagian siswa melakukan kesalahan dalam memahami, kesalahan dalam mentransformasi, kesalahan dalam keterampilan proses kesalahan penulisan jawaban akhir. Penyebab kesalahan ini adalah siswa tidak mengetahui apa yang sebenarnya ditanyakan dalam soal, dan tidak sengaja mendapatkan informasi pada soal tersebut, sehingga mereka tidak dapat melengkapi informasi untuk langkah selanjutnya, tidak mengerti bagaimana menjelma menjadi sebuah pertanyaan. model matematika, dan tidak mahir dalam menghitung.
