Abstract. This study aims to describe students' mistakes in completing algebraic form operation questions based on Newman's stages. This research approach is a qualitative approach using descriptive research types. Data collection techniques were carried out by test and interview methods. The validity test of the data is done by source triangulation. The results showed that the mistakes made by students were a reading error of 44.4%, understanding the problem of 72.2%, transformation of 44.4%, process skills of 44.4%, and answer writing of 77.8%. The cause of students' mistakes is because they cannot mention the keywords or symbols on the questions, students do not understand the problems that exist in the questions, students do not write down the procedures used, make mistakes in calculations so that the final answers are wrong, and errors in writing units.
Keywords - Error Analysis; Newman Stages; Algebraic Formation Operations.
Abstrak. Penelitian ini bertujuan untuk mendeskripsikan kesalahan siswa dalam menyelesaikan soal operasi bentuk aljabar berdasarkan tahapan Newman. pendekatan penelitian ini adalah pendekatan kualitatif dengan menggunakan Jenis penelitian deskriptif. Teknik pengumpulan data dilakukan dengan metode tes dan wawancara. Uji keabsahan data dilakukan dengan triangulasi sumber. Hasil penelitian menunjukkan bahwa kesalahan yang dilakukan siswa adalah kesalahan membaca sebesar 44.4 %, memahami soal sebesar 72.2 %, transformasi sebesar 44.4 %, ketrampilan proses sebesar 44.4 %, dan penulisan jawaban sebesar 77.8 %. Penyebab kesalahan siswa dikarenakan tidak dapat menyebutkan kata kunci atau simbol yang ada pada soal, siswa kurang memahami masalah yang ada pada soal, siswa tidak menuliskan prosedur yang digunakan, melakukan kesalahan dalam perhitungan sehingga jawaban akhir salah, dan kesalahan dalam menuliskan satuan.
