The effect of learning motivation and interest in learning shape the ability to write scientific papers. The research method used is a survey method. The sample is randomly selected, 65 students. Data collection was carried out by direct observation techniques and by distributing questionnaires. Data analysis used statistics, namely correlation test, coefficient of determination, and regression test. The results of the multiple linear regression test obtained the following equation: Y = 80,623 + 0,065 X1 + 0,086 X2. The influence of the learning motivation variable (X1) is 44,5%, and the influence of the learning interest variable (X2) is 26,9%. These calculations show that the influence of learning motivation is greater than interest in learning. Then, from the calculation of determination, R square or coefficient of determination of 0,020 means that 20% of the ability to write scientific papers is influenced by learning motivation and interest in learning meanwhile other variables outside the equation influence the rest. Keyword: learning motivation, learning interest, student’s writing ability Abstrak Tujuan penelitian ini adalah memahami pengaruh motivasi dan minat belajar terhadap kemampuan menulis karya ilmiah siswa. Motivasi dan minat secara bersama-sama berpengaruh terhadap kemampuan menulis karya ilmiah. Metode penelitian yang digunakan adalah metode survei, sampel dipilih secara random 65 siswa. Pengumpulan data dilakukan dengan teknik penyebaran angket. Analisis data menggunakan statistik uji regresi. Hasil uji regresi linier berganda memperoleh persamaan: Y = 80,623 + 0,065 X1 + 0,086 X2. Besar pengaruh variabel motivasi belajar (X1) adalah 44,5% dan pengaruh variabel minat belajar (X2) adalah 26,9%. Dari perhitungan tersebut menunjukkan bahwa pengaruh motivasi belajar lebih besar daripada minat belajar. Hasil perhitungan determinasi diperoleh R square atau koefisien determinasi sebesar 0,020. Artinya, kemampuan menulis karya ilmiah sebanyak 20% dipengaruhi oleh motivasi belajar dan minat belajar secara bersama-sama, sedangkan sisanya dipengaruhi oleh variabel lain. Kata kunci: motivasi belajar, minat belajar, kemampuan menulis karya ilmiah
