Each student has different abilities in problem solving, especially in story problems. Haji (1994: 13) suggests that questions that can be used to determine students' abilities in the field of mathematics study can take the form of story problems. The purpose of this research is to describe the ability of students to solve mathematical problems in solving comparative story problems based on Polya'sÂ steps. This research is a descriptive study using a qualitative approach. Three (3) subjects were taken from students of class VIIA at SMP Negeri 1 Wamena consisting of one high ability student, one medium ability student, and one low ability student. Retrieval of data taken by the test and interview methods. The test used was in the form of a description test of three (3) questions. Based on the research results obtained: the ability to solve mathematical problems in High Ability Students (SKT) can do all the problem solving comparative story problems based on Polya steps, while the Medium Ability Students (SKS) there are two questions that have not fully taken Polya's steps specifically implementing the completion plan and check again. For Low Ability Students (SKR) almost all the questions given cannot be solved using Polya steps.Keywords: Problem solving, Polya steps, comparison problems.

Latar belakang penelitian ini adalah rendahnya hasil belajar mahasiswa pada materitrigonometri . Penelitian ini bertujuan untuk menganalisis kesulitan yang dialami mahasiswadan faktor-faktor penyebab kesulitan mahasiswa memahami materi trigonometri. Subjek dalampenelitian ini adalah mahasiswa semester 1 STKIP Abdi Wacana Wamena Program StudiPendidikan Matematika sebanyak 43 mahasiswa. Jenis penelitian ini merupakan penelitiandeskriptif kualitatif. Teknik pengumpulan data yang digunakan hasil tes dan Kuisioner (angket).Analisis data meliputi reduksi data, penyajian data dan penarikan kesimpulan. Berdasarkanhasil penelitian diperoleh kesulitan mahasiswa dalam memahami materi trigonometri yaitupertama kesulitan konsep yang meliputi (1) mahasiswa mengalami kesulitan memahami soalyang diberikan, (2) Mahasiswa tidak dapat mendefenisikan perbandingan trigonometri sesuaisudut yang diketahui pada gambar, (3) mahasiswa tidak dapat memahami konsep phytagorasuntuk mencari panjang salah satu sisi segitiga yang ditanyakan, mahasiswa tidak memahamipenggunaan tanda negatif dan positif pada kuadran I,II,III dan IV. Kedua kesulitan penggunaanprinsip yang meliputi (1) mahasiswa tidak dapat menentukan rumus sudut berelasi yangdigunakan, (2) mahasiswa tidak dapat menerapkan konsep penggunaan kuadran dalammenyelesaikan soal, (3) Mahasiswa tidak dapat menuliskan rumus phytagoras dengan benardan ketiga kesulitan keterampilan yaitu mahasiswa tetapi tidak melakukan perhitungan dalambentuk akar. Faktor penyebab mahasiswa mengalami kesulitan yaitu faktor intern yang meliputiminat, motivasi, bakat dan intelegensi sebesar 3,94 % dan faktor ekstern yang meliputi tenagapendidik (Dosen) 3,55 %
