Penelitian ini bertujuan menghasilkan instrumen tes diagnostik untuk mengukur learning loss siswa pada materi eksponen dan logaritma. Tes diagnostik yang dikembangkan tersusun dari 13 soal pilihan ganda dengan satu jawaban benar dan empat jawaban pengecoh yang dapat diakses melalui e-learning. Penelitian ini merupakan penelitian Research & Development (R & D) dengan menggunakan model pengembangan Tessmer yang terdiri dari empat tahap yaitu preliminary, self evaluation, prototyping, dan field test. Instrumen penelitian yang digunakan adalah lembar validasi dan angket siswa. Subjek uji coba dalam penelitian ini merupakan siswa SMAN 3 Banda Aceh kelas X-1 dan X-2 yang berjumlah 69 siswa. Uji validitas dilakukan oleh tiga validator yang menunjukkan instrumen tes diagnostik dalam kategori valid. Hasil analisis butir soal pada tahap field test didapatkan 12 butir soal tergolong valid dan memiliki nilai reliabilitas yang tinggi sebesar 0,713. Terdiri atas 7 soal dengan tingkat kesukaran sedang dan 6 soal dengan tingkat kesukaran mudah. Daya pembeda soal sebanyak 6 soal dengan kategori baik, 5 soal dengan kategori cukup, dan 2 soal dengan kategori lemah. Hasil analisis pengecoh didapatkan 8 soal memeiliki pengecoh dengan kategori cukup baik. Berdasarkan hasil uji coba field test ditemukan 71% dari 69 siswa yang mengikuti tes mengalami learning loss pada materi eksponen dan logaritma.

This research aims to produce a diagnostic test instrument to measure student learning loss in exponent and logarithm material. The diagnostic test developed consists of 13 multiple choice questions with one correct answer and four distractor answers which can be accessed via e-learning. This research is Research & Development (R & D) research using the Tessmer development model which consists of four stages, namely preliminary, self evaluation prototyping, and field test. The research instruments used were validation sheets and student questionnaires. The test subjects in this research were students of SMAN 3 Banda Aceh classes X-1 and X-2, totaling 69 students. The validity test was carried out by three validators who showed that the diagnostic test instrument was in the valid category. The results of the analysis of the questions at the field test stage showed that 12 questions were classified as valid and had a high reliability value of 0.713. Consisting of 7 questions with a medium difficulty level and 6 questions with an easy difficulty level. The differentiating power of the questions is 6 questions in the good category, 5 questions in the sufficient category, and 2 questions in the weak category. The results of the distractor analysis showed that 8 questions had distractors in the quite good category. Based on the results of the field test, it was found that 71% of the 69 students who took the test experienced learning loss in the material on exponents and logarithms.
