Hum. 2018 Penelitian ini bertujuan untuk mengetahui (1) kontribusi penguasaan kosakata, minat membaca, dan motivasi belajar terhadap pemahaman membaca; (2) kontribusi penguasaan kosakata terhadap pemahaman membaca; (3) kontribusi minat membaca terhadap pemahaman membaca; (4) kontribusi motivasi belajar terhadap pemahaman membaca pada kelas VIII di MTs Negeri Surakarta II tahun pelajaran 2017/2018. Jenis penelitian ini adalah penelitian kuantitatif asosiatif. Sampel dalam penelitian ini berjumlah 171 siswa yang telah diambil dengan menggunakan teknik area sampling acak. Teknik untuk pengumpulan data menggunakan tes dan kuesioner. Peneliti menggunakan SPSS versi 21.0 untuk analisis data yang terdiri dari statistik deskriptif, uji asumsi klasik (normalitas, linieritas, multikolinearitas, heteroskedastisitas), regresi berganda dan pengujian hipotesis yang terdiri dari uji-t (partial), uji-f (simulasi), koefisien determinasi, dan kontribusi prediktor. Hasil penelitian ini menunjukkan bahwa (1) adanya kontribusi penguasaan kosakata, minat membaca, dan motivasi belajar terhadap pemahaman membaca dengan nilai Fhitung lebih tinggi dari Ftabel (38,422 > 2,68) dan nilai signifikan sebesar 0,000 < 0,05; (2) adanya kontribusi penguasaan kosakata terhadap pemahaman membaca dengan nilai thitung lebih tinggi dari ttabel (10,225 > 1,960) dan nilai signifikan sebesar 0,000 < 0,05; (3) adanya kontribusi minat membaca terhadap pemahaman membaca dengan nilai thitung lebih tinggi dari ttabel (2,292 > 1,960) dan nilai signifikan sebesar 0,023 < 0,05; (4) adanya kontribusi motivasi belajar terhadap pemahaman membaca dengan nilai thitung lebih tinggi dari ttabel (2,546 > 1,960) dan nilai signifikan sebesar 0,012 < 0,05. Hasil dari determinasi koefisien (R 2 ) adalah 40,8%. Hasil diatas menunjukkan bahwa adanya kontribusi yang positif dan signifikan antara variabel-variabel bebas terhadap variabel terikat secara terpisah maupun secara bersamaan. Secara statistik, penguasaan kelas kata mempunyai hasil kontribusi tertinggi di variabel penguasaan kosakata siswa, kesadaran memiliki hasil kontribusi tertinggi di variabel minat membaca siswa, ekstrinsik mempunyai hasil kontribusi tertinggi di variabel motivasi belajar siswa, dan mengidentifikasi pokok pikiran mempunyai hasil kontribusi tertinggi di variable pemahaman membaca siswa.

ABSTRACT Khotimah, Fitriana Nurul. S200160056. The Contribution of Vocabulary Mastery, Reading Interest, and Learning Motivation toward Reading Comprehension of the eighth grade students at MTs Negeri Surakarta II in academic year of 2017/2018. Thesis. Magister of Language Studies. Graduate School of Muhammadiyah University of Surakarta. The Primary Supervisor is Dr. Maryadi, M. A., and the Co-Supervisor is Dr. Anam Sutopo, M. Hum. 2018 This research is aimed as knowing: (1) the contribution of vocabulary mastery, reading interest, and learning motivation toward reading comprehension; (2) the contribution vocabulary mastery toward reading comprehension; (3) the contribution reading interest toward reading comprehension; and (4) the contribution learning motivation toward reading comprehension of the eighth grade students at MTs Negeri Surakarta II in academic year 2017/2018. The type of this research is quantitative associative research. The sample of this research was 171 students taken by cluster random sampling technique. The technique to collect data used test and questionnaire. The researcher used SPSS version 21.0 to analyze the data which consist of descriptive statistic, classic assumption test (normality, linearity, multicolinearity, and heteroscedasticity), multiple regressions and hypothesis testing such as t-test (partial), f-test (simulation), coefficient of determination, and predictor contributions. The result of this research shows that: (1) there is a positive and significant contribution of vocabulary mastery, reading interest, and learning motivation toward reading comprehension with the value of Fresult is higher than Ftable (38,422 > 2,68) and the significance value is 0,000 < 0,05; (2) there is a positive and significant contribution of vocabulary mastery toward reading comprehension with the value of tresult is higher than ttable (10,225 >1,960) and the significance value is 0,000 < 0,05; (3) there is a positive and significant contribution of reading interest toward reading comprehension with the value of tresult is higher than ttable (2,292 > 1,960) and the significance value is 0,023 < 0,05; and (4) there is a positive and significant contribution of learning motivation toward reading comprehension with the value of tresult is higher than ttable (2,546 > 1,960) and the significance value is 0,012 < 0,05. The result of coefficient determination (R 2 ) is 40,8%. The result above shows that there are positive and significant contributions of independent variables toward dependent variable individually and simultaneously. Statistically, mastering word classes have the highest contribution in students vocabulary mastery, consciousness have the highest contribution in students reading interest, extrinsic motivation have the highest contribution in students learning motivation, and identifying main idea have the highest contribution in students reading comprehension.
