INDONESIAN VOCABULARY WRITING ON INSTAGRAM USERS ON THE ABILITY TO WRITE EXPOSITION TEXT

Abstract

ABSTRACT: The background of this research is that the 2013 curriculum was developed by improving individual and group learning patterns while still paying attention to the development of potential especially that of each student, one of which is the ability of students to write descriptive texts. The thing that often becomes an obstacle in writing is the lack of vocabulary mastery, even though vocabulary determines how skilled a person is in language. The richer the vocabulary we have, the more likely we are to be skilled at language. This study aims to: (1) determine whether or not there is an effect of vocabulary mastery on the ability to write exposition for students of SMA Muhammadiyah 1 Medan; (2) know whether or not there is an influence of mastery of Indonesian grammar on the ability to write an exposition of the tenth-grade students of SMA Muhammadiyah in Medan City; and (3) to find out whether or not there is an effect of mastery of Indonesian vocabulary and grammar on the ability to write an exposition of students of SMA Muhammadiyah in Medan. The research subjects were students of class X SMA Muhammadiyah in Medan City taking a sample of 250 students. The sampling technique used a stratified random sampling technique. Vocabulary, grammar, and writing exposition data were collected by means of an ability test. The data analysis technique used is product moment analysis and multiple linear regression analysis. Based on the results obtained there are 44 students (12.75%) students have mastery of vocabulary on the ability to write exposure in the high category, 251 students (72.72%) students in the medium category and 50 students (14.50%) students have the ability low.
