Abstrak

Logaritma memiliki peran penting dalam pembelajaran matematika, karena berbagai bidang seperti sains, komputer, keuangan, industri, dan lain-lain menerapkan materi ini sebagai salah satu mata pelajarannya. Khususnya dalam kalkulus, logaritma memiliki peranan penting terutama logaritma natural. Penelitian ini bertujuan untuk mengetahui kesulitan calon guru matematika dalam menyelesaikan permasalahan basis dan numerus pada logaritma. Subjek dalam penelitian ini adalah mahasiswa semester awal di salah satu universitas di kota Banda Aceh yang mengambil mata kuliah aljabar elementer. Penelitian dilakukan dengan pendekatan deskriptif untuk menjelaskan kesulitan yang dihadapi siswa dan menerapkan beberapa langkah seperti memberikan tes logaritma kepada siswa, menentukan kesulitan dan memverifikasi dengan mewawancarai siswa yang mengalami kesulitan berdasarkan jawaban mereka. Hasil penelitian ini menunjukkan bahwa terdapat berbagai kesulitan yang dihadapi mahasiswa yaitu; (1) kurang memahami definisi basis dan numerus logaritma, (2) tidak dapat membedakan ekspresi dan persamaan logaritma, (3) mengingat terlalu banyak rumus sehingga tidak memahami konteks soal, (4) tidak dapat menentukan posisi bilangan irasional pada garis bilangan.
