From the table 5 above, the correlation between vocabulary and sentence structure mastery towards reading comprehension is significant. Ho is rejected and Hi is accepted. It is proven by the score of Sig. 05 and F-test = 15. Meanwhile, regression linearity shows that ycUC = 347 0. 316 X1 0. 290 X2. means when the score of one variable, vocabulary or sentence structure mastery, increases about X1 = 0. and X2 = 0. 290, it will give a reading comprehension. From table 6 above, it shows the correlation between vocabulary comprehension is significant. Ho is rejected and Hi is accepted. It is proven by the score of Sig. 05 and t-test = 2. From table 4 also proves that vocabulary mastery correlates in contributing about 32. towards reading comprehension. Furthermore, the variable vocabulary mastery towards reading comprehension will be tested using a formula below: R2 = Score yuycu1yc x Partial Correlation Score . cycu1yc ) x 100 % R2 = 0. 333 x 0. 499 x 100 % = 16. From the calculation above, it is stated that the contribution of vocabulary mastery improves the reading comprehension about 16. Table 6 shows that the sentence structure mastery contributes significantly towards the reading Ho is rejected and Hi is accepted. It is proved from the score of Sig. 0,011 < 0. 05 and t-test = 2. The contribution of the variable of sentence structure mastery can be formulated as follows: R2 = Score yuycu2yc x Partial Correlation Score . cycu2yc ) x 100 % R2 = 0. 318 x 0. 492 x 100 % = 15. From the calculation above, it can be interpreted that the contribution of sentence structure mastery will improve the reading comprehension CONCLUSION There is a significant correlation between vocabulary and sentence structure mastery towards reading It is proven by the score of Sig. 000 < 0. 05 and F-test = The contribution is about There is a significant It is proven by the score of Sig. 008 < 0. 05 and t-test = It contributes about 16. The sentence structure mastery contributes significantly towards the reading comprehension. It is proven from the score of Sig. 0,011 < 0. and t-test = 2.
