This research used Quasi-Experiment design. This research involved two classes IX A and IX B as the sample of this research. IX A was selected as experimental class and IX B was selected as control class. In the experimental class, vocabulary was taught by using My Dictionary Application. While, in the control class, vocabulary was taught by using with the conventional media. The data was collected from pre-test dan post test. Then , the data obtained was analyzed by using SPSS. The result of the study showed that teaching vocabulary by using My Dictionary Application significantly improving students’ vocabulary. The findings showed that the mean of Experiment class students was 25.20, and the control class means score was 21.40. After treatment given, there is a significant increase. The means of the Experiment class is 48.40, and the class of the control class is 30.50. After that compared between posttest result class experiment with control class result is t (result the research) = Σ X1 - Σ X2 = t = 48, 40 - 30, 50 = 19.00. Where Σ X1 (experiment class)> Σ X2 (control class). This means that the use of my dictionary application gives effect to vocabulary mastery of students.

Especially with the development of the increasingly demanding era of all people to be able to use English language so that increasing the English language is increasingly important to learn. In the world of today, where English has become the part and parcel of every aspect of life, teaching and learning it is gaining impetus (Pathan, 2016). Vocabulary is one aspect in English.

This means that the teacher needs to use effective media that can make the interest in learning. Technology is such a big part of the world of w which we live. According to Costley (2014), the use of technology and teaching students have to use it has become a high priority in the public schools. Another reason technology is a factor improving learning is the fact that technology is becoming such an integral part of our everyday world. Most jobs today require some type of technology use. Also, students and adults are using technology on a daily basis to communicate, get information in multiple ways. The prevalent daily use of technology in people’s lives overall makes the use of technology very relevant to the students and provides a connection that will greatly benefit student teaching. This means that the use technology can help students improve their achievement. My dictionary application is one result of technological developments that anyone can get through his smart phone. Thus, this study aims to know the result of enhancing students’ vocabulary mastery by using My Dictionary Application. B. LITERATURE REVIEW 1. Vocabulary Vocabulary is vital parts of language. Without words, language will be difficult to be made. Vocabulary can be seen as bricks in a building while the building is the language. It means that by having a good amount of vocabulary, we can use the language well. No one can learn a language without learning its vocabulary (Huda, 2016) This means that vocabulary is one of the language aspects which should be learn learning vocabulary to enable one to speak, write, and listen. A person said to know a word if he can recognize it is meaning when he see it (Cameron, 2001: 75). It means that in learning vocabulary the learners have to know the meaning of the new words it and also understand and can use it sentence context. According Linse (2002:121), vocabulary is the collection of words that an individual knows. Vocabulary is one of the language system components that is important to be learned.Vocabulary is the total number of words in a language; all the words know a person particular subject, a list of words with their meaning, especially one that accompanies a textbook (Hornby, 1995: 1331). Those definition shows that vocabulary is the first element that English learners should learn on order to master English well besides the other English components and skills. In language learning, vocabulary takes place in building the language proficiency. The objective of the vocabulary mastery is to enable the students to have a good language proficiency in the language skills. It depends on the quality and quantity of the vocabulary that they have mastered. The richer the vocabulary that can be mastered by the students they will get the better skill that can be reached in using language. Therefore, it can be concluded that knowing a word (vocabulary) means knowing about meaning, word use, word formation, and word grammar (Harmer, 1991: 158). 2.

Classes IX A is experimental and IX B is as control group.The data was collected from pre-test and post test. Then, then the data was analyzed by using t- test. D. FINDINGS AND DISCUSSION The researcher got the result value data from pretest and posttest of experiment class and control class as follows: Table 1.

This means thatt H0 rejected and H1 accepted that there are differences in English learning results by using of my dictionary application and by using conventional media. In addition, The data above explains that the average grade of experimental class posttest in reducing the posttest grade of the control class still shows the value of 19.00 and not minus. It shows that my dictionary use is better than the lecture method. ELTIN Journal, Volume 7/I, April 2019 42 E. CONCLUSION Based on the findings mentioned above, it can be concluded that the use of My Dictionary Application is very helpful in improving students' vocabulary mastery. This is can be seen from the average value obtained from the larger experiment class that is 48, 40 compared to the control class which is only 30, 50, and also described in the Independent sample test table in the sig column (2 Tailed) in the posttest row there is a value of 0,000 which shows that there is a difference between experiment class and control. In addition, the use of My Dictionary Application can develop and improve students' vocabulary skills compared to using lecture methods.
