Penelitian ini merupakan penelitian kualitatif yang bertujuan untuk menggambarkan kemampuan pemecahan masalah matematika berdasarkan langkah polya pada materi SPLDV ditinjau dari kepribadian siswa tipe phlegmatis (PE). Instrumen dalam penelitian ini adalah tes kepribadian, tes pemecahan masalah matematika serta pedoman wawancara. Tes kepribadian digunakan untuk mengelompokkan siswa berdasarkan kepribadiannya, tes pemecahan masalah akan digunakan untuk menunjukkan kemampuan siswa dalam memecahkan masalah matematis berdasarkan langkah polya, dan pedoman wawancara berisi sejumlah panduan yang bertujuan mengklarifikasi jawaban dan menelusuri proses berpikir siswa secara mendalam. Data dikumpulkan melalui tes dan wawancara dan dianalisis dengan menggunakan model analisis data Miles dan Huberman. Proses penelitian mengikuti tahap-tahap: (a)merumuskan indikator pemecahan masalah matematika berdasarkan langkah polya, (b)merumuskan instrumen pendukung (tes penggolongan tipe kepribadian, tugas pemecahan masalah matematika dan pedoman wawancara) yang valid dan reliabel, (c)melakukan pengambilan subjek penelitian dengan memberikan penggolongan tipe kepribadian, (d)melakukan pengambilan data untuk mengungkap deskripsi pemecahan masalah matematika yang dilakukan oleh siswa, (e)melakukan triangulasi waktu untuk mendapatkan data yang valid, (f)melakukan analisis data pemecahan masalah berdasarkan tipe kepribadian, (g)melakukan pembahasan hasil analisis, (h)melakukan penarikan kesimpulan hasil penelitian. Â Hasil penelitian menunjukkan bahwa subjek phlegmatis melakukan pemecahan masalah mengikuti langkah-langkah Polya yakni: (1)memahami masalah, (2)merencanakan penyelesaian, (3)melakukan rencana penyelesaian, (4)memeriksa kembali.
