THE CORRELATION BETWEEN STUDENTS’ VOCABULARY MASTERY AND THEIR TRANSLATION ABILITY AT THE FIRST SEMESTER OF THE ELEVENTH GRADE OF MAN 2 BANDAR LAMPUNG IN THE ACADEMIC YEAR OF 2017/2018

In this research, the researcher focused on the correlation between students’ vocabulary mastery and their translation ability. The objective of the research was to know whether there was a correlation between students’ vocabulary mastery and their translation ability at the first semester of eleventh grade of MAN 2 Bandar Lampung in the academic year of 2017/2018. There were two variables in this research, the independent variable, vocabulary mastery (X) and dependent variable, Translation ability (Y). This is correlational research, it is used to know the correlation between vocabulary mastery and translation ability. In taking the sample of the research, the cluster random sampling was applied. The population of the research was taken from the students of eleventh grade of MAN 2 Bandar Lampung in the academic year of 2017/2018. The sample of the research was taken 39 students from 197 populations. In collecting the data of the research, the researcher used objective test that were multiple choices consisted 20 items and one text for translation test. In this research, SPSS was used to compute Pearson Product Moment’s formula.After doing the hypothetical testing, the result demonstrated that there was positive correlation between students’ vocabulary mastery and their translation ability. Based on the data analysis computed by SPSS, it was obtained that Sig (P Value) = 0.000 and α=0.05. It means that Ha was accepted and Ho was rejected because Sig (P Value) =0.000 < α=0.05. Based on this research, it was suggested that to have a good ability in translating, the students should have a good mastery of vocabulary.

of communications through which consist of a set of sounds and written symbols which are used by the people of a particular country for talking of writing. It means that the language is very important in human life. Without language they cannot deliver their feelings, opinions, and thoughts to each other. It is difficult to do all activities without language.
Nowadays, English plays an important role in the world. As an international language, it is used to disseminate information and news around the world. For our country, English helps the Indonesian people be cognizant of the development and their knowledge.
English also becomes very important for people to exchange meaning and represent their feeling and idea. Learning a foreign language is different from learning one's mother tongue. The students will meet a lot of difficulties in learning a foreign language (the target language/TL) because each language has its own vocabulary items and unfamiliar ways of arranging the words into sentences.
Based on this problem, translation is considered a very important thing to connect the two different languages by contributing source language (SL) into target language. Catford defines that translation is the replacement of textual material in one language (source language) by equivalent textual material in another language(target language). It means that translation is an activity of rewriting a text from its source language into the target language without modifying or changing its meaning in order to make the information in the source language become acceptable and understandable for students.
In teaching learning English as foreign language, the students have to be able to understand words. If they do not understand and do not know the meaning of English vocabulary, they will get difficulties in learning foreign language especially English. In this case, translation is needed to understand what people express and say in their languages, write in their letters, and communicate with their friends.
Translation is not an easy job that can be done by anyone without knowing the procedures, methods and techniques of translating. Then, Ordudari in Translation Journal states that the difference between the source language and the target language and the variations of their culture make the process of translating a real challenge. Among the problematic factors involved in translation are form, meaning, style, proverbs, idioms, grammar mastery and vocabulary mastery. It means that in translating, the difference culture is the challenge for translator. In translation there are some factors such as, form, meaning, style, proverb, idioms, grammar mastery and vocabulary mastery.
Something influential of translation is the vocabulary mastery. Vocabulary plays an important role in learning English. Like other languages, in learning English, learners have to be able to understand words. In fact, it happens that students want to express something in English but they do not know how to express the word appropriately because of the lack of vocabulary. Therefore, Snow et.al cited in Tankersly states that vocabulary is the meaning and pronounciation of words that we use in communication. It means that vocabulary is the vital part of language that students used in communication. Without vocabulary it is impossible for them to learn language. By mastery vocabulary, they will be easy to communicate to each other.
Vocabulary development is an important aspect of language development. In dealing with vocabulary, one should consider three important aspects of vocabulary such as how word form, how word meaning, and also how word usage. Word formation means to know how words are spoken, written, and how they can change their form. Then meaning encompasses the way that form and meaning work together in other words, the concept and what items it refers to, and the association that come to mind when people think about a specific word or expression. These are to realize about vocabulary items that they frequently have more than one meaning. Sometimes, word has meanings in relation to other words. The meaning of language depends on where it occurs within a large stretch of discourse. Here, the grammatical function use of the words or phrase, the collocation that normally occur with a language use, and any constraints used (in term of frequency, level, so forth).
Regarding the explanation, the researcher summarizes that in general, vocabulary can be classified into some part covering all words in language. After knowing some points of vocabulary, it is clear that the students should have a great skill on vocabulary. Not only mastery in a rich vocabulary but also understand about using of vocabulary adequately.
In preliminary research at MAN 2 Bandar Lampung, the researcher asked Mrs. Wahyu Fardushila, S.Pd as the English teacher about the students' capability in English, especially about their vocabulary mastery and their translation ability. She said that that students got difficulty in translating because they lack of vocabulary.
In doing preliminary research, the researcher got the data of vocabulary mastery of the eleventh grade of MAN 2 Bandar Lampung. It can be seen from table of the students' score given by the teacher below: The researcher also did preliminary research to get students' translation ability score. Students' translation ability score is as follows: two things which were discussed in this study, vocabulary mastery and reading comprehension. The objective of this study was to show the correlation between vocabulary mastery and reading comprehension. Increasing vocabulary skill is one of the most important things to reach the students goal in comprehension skills. The research findings showed that the vocabulary mastery affected the students' performance in reading comprehension. As the influence is positive one, it supported the basic assumption that the students who got high score in vocabulary test, they would get the score in comprehension as well. It means that the more students have many stocks of words, the better they perform in comprehension.
Dealing with discussion above, it is predicted that the students who are good in vocabulary will be able to translate well. This research is done for the intention of exploring how significant the vocabulary mastery and translation. Therefore the researcher conducted a research entitled: "The Correlation between Students'

Vocabulary Mastery and Their Translation Ability at the First Semester of Eleventh
Grade of MAN 2 Bandar Lampung in the Academic Year of 2017/2018."

B. Formulation of the Problem
Referring to the problem above, the researcher formulated the main problem as follows; is there any correlation of students' vocabulary mastery and their translation ability?

Theoretically
This research hopefully gave information about vocabulary mastery and translation ability. This research also enriched the previous studies about the correlation between vocabulary mastery and translation ability.

Practically
The practical as significance that the researcher expected from this research are as follows: a. For students: the finding of the research will motivate them to practice more than they did before and encourage them to learn English by improving their vocabulary mastery through some fun ways. In addition, by improving their vocabulary mastery, they will be able to increase their translation ability.
b. For teachers: the result of the research will be useful as a reflection in order to increase and develop their method in teaching students about vocabulary relating to its importance in their ability in translation.
c. For other researchers: the finding of the research hopefully can be useful as the source of their reference and it is also useful to inform the readers about the correlation between students' mastery of vocabulary and their translation ability of the eleventh grades of MAN 2 Bandar Lampung.

Vocabulary Mastery
Vocabulary is the first basic important aspect for learning English by learner, by mastering vocabulary they are able to communicate both orally and written well.
Also by having a lot of vocabularies, the students are hoped to master four skills in English such as: listening, speaking, reading and writing.
Meanwhile, Hornby states that mastery is great knowledge about or understanding of a particular thing. From that definition, it comes to the conclusion that mastery means the competency to understand and apply something learnt.
Seeing the explanation, the researcher concludes that vocabulary mastery is the ability to know the meanings of certain vocabulary items and their usage in certain context to express ideas, opinion, and feelings in communication. In other word, vocabulary mastery is people's ability to use or to understand words of language that they have learned in certain situations which they really have experienced in their lives.

2.Translation Ability
Translation typically has been used to transfer written or spoken of source language texts to equivalent written or spoken TL texts. In other word, translation is a change of form from one language into another one both oral and written language.
Meanwhile, Hornby states that ability is able to do. It means that ability is the capacity of someone to carry out a particular thing.
The ability in translating a language into another language is indicated by the quality of translation result. Translation ability can be achieved if translator (students') is able to generate target text and can adapt to the reader. It requires a good translator. Translator is someone who has the comprehensive knowledge of both source and target language. According to Newmark "a translator requires knowledge of literary and non-literary textual criticism, since he/she has to the quality of a text before he decides how to interpret and then translate it". It means that translation is the ability which of course requires certain qualification of translator. A translator has to understand the written message in the foreign language before transferring into target language.
Regarding the explanation, good translator is one of top key in translation activity so that the successful of this activity depend on the students' knowledge. They must give more attention to the reader in target language. A translator must be also being accountable for his or her translation works by considering compatibility between source text and target text. That's way, he or she can create good translation.
In translating activity, it possible that someone facing some problems to translate from source language (SL) into a target language (TL

Sample
Sample is a small portion of population. According to Lodico et al "A sample is a smaller group selected from a larger population (in this case, a realistic population) that is representative of the larger population". It means that sample is a representative part of population that was took to represent the research. The sample of this research was class XI MIA 2 at MAN 2 Bandar Lampung.

The Sampling Technique
Sampling is the process that used to select the sample. As Fraenkel et al defined that sampling was the selection of the sample of individuals who will participate (be observed or questioned). It had purpose to gain information about a population.
Here, sampling is very important way to obtain a group of a subject who will be representative of the larger population or will provide specific information needed.
In this research, the researcher used cluster random sampling technique because the population is in groups and homogenous.
In MAN 2 Bandar Lampung the number of the eleventh grade are 5 classes namely: XI MIA 1, XI MIA 2, XI MIA 3, XI MIA 4 and XI MIA 5.
Here are the steps that followed by researcher to determining the sample: 1. First, the researcher provided 5 pieces of paper consisting of five classes, XI MIA 1, XI MIA 2, XI MIA 3, XI MIA 4 and XI MIA 5.
2. Next, the researcher rolled those pieces of paper and put them into a box.
3. Then, the researcher shook the box until the one rolled paper came out of it.
Then, this rolled paper took as the sample. It was gotten XI MIA 2 as a sample of this research.

B. The Data Collecting Technique
Collecting data is the most important step in conducting the research. In collecting data in this research, the researcher used a test. According to Donal ary, test is a set of stimuli presented to an individual in order to elicit responses on the basis of which a numerical score can be assigned. It means that a test is a device that contains pISSN 2086-6003│eISSN 2580-1449 Vol 14 (2), 2021, 69-91 English Education: Jurnal Tadris Bahasa Inggris, Vol. 14 (2), 2021, 79 a series of the task to do or questions to be answered by someone to measure the one aspect specific behavior. Thus, the function of the test is as a tool to measure.
Before conducting the real test, the researcher conducted a try out test to get the validity and reliability of each test item. In this research, the researcher gave two kinds of tests, namely vocabulary and translation to get the data or information.

C. The Instruments
Sugiyono states that research instrument is a tool used by researcher to measure the nature or social phenomena being observed. Here, it had purpose as a tool to get the data. It is used to measure the students' ability and to get the data to prove the  There are no mistake in using vocabulary, there are any grammar and spelling mistake but not many.
The translation is good 65-75 There are grammar and idiom mistakes but not more than 15% from all texts.
There are any mistakes in spelling.
The translation is enough 46-60 There are grammar and idiom mistakes but not more than 25% from all texts.
There are any mistakes in uncommon vocabulary.
The translation is worse 20-45 There are grammar and idiom mistakes more than 25% from all texts.  To analyze the data, the researcher used parametric statistics. In parametric statistics, there Linearity test is used to know the size of the linear relationship between two variables x and y. before analyzing the data by using Pearson's product moment formula to know correlation level.

Result of the Vocabulary Mastery Test
The test was conducted in order to know the students' vocabulary mastery. The test was administered in MAN 2 Bandar Lampung onOctober 31 th , 2017. The minimum score was 40 and the maximum score was 95. There were 1 student who got the score 40, 1 student who got the score 90, and 18 students got score lower than 75.
The mean of the vocabulary mastery test is 68.59.

Result of Translation Ability Test
Based on the figure 1, it can be seen that there were 28 students who got score under average scores and 11 students who got the score over average score (Standard Minimum of Criteria).

Fulfillment of Assumptions
Before knowing the result of the data analysis by using Pearson Product Moment's formula, there were two assumptions that must be done and found out. They were normality test and linearity test.

a. Result of Normality Test
The normality test is used to measure whether the data in the vocabulary mastery and translation ability were normally distributed or not. In this research, statistical computation by using SPSS (Statistical Package for the Social Science) was used for normality of the test. The test normality employed were Kolmogorov -Smirnov and Shapiro -Wilk. Hοis accepted if Sig (P Value)>α = 0.05.
The hypotheses for the normality test were formulated as follows: Ho : The data are normally distributed.
Ha : The data are not normally distributed.
While the criteria acceptance and rejection of normality test are: Ho is accepted if sig > α =0.05 Ha is accepted if sig < α = 0.05 Table 11 Result of Normality Test *. This is a lower bound of the true significance.
Based on the table above, it can be seen that Sig (P value) for vocabulary mastery was 0.258 and Sig (P value) for translation ability was 0.142. Because Sig (P value) of vocabulary mastery and translation ability higher than 0.05 it means Ho was accepted. The conclusion was that the data in vocabulary mastery and translation ability had normal distribution.

. Result of Linearity Test
The test was intended to test whether the data obtained were linear or not because this was one of requirements to be able to use the Pearson product moment formula.
The researcher used SPSS Statistic 16.0 and the result was as follow: Table 12 Result of Linearity Test ANOVA Sig (Pvalue) > α. The conclusion was that the data were linear.

Result of Hypothetical Test
The hypothesis is very important to find out whether or not the alternative (

B. Discussion
The findings of the research showed that there was significant correlation between students' vocabulary mastery and their translation ability. to see students' vocabulary mastery. The minimum score was 40 and the maximum score was 95. There were 1 student who got the score 40, 1 student who got the score 90, and 18 students got score lower than 75. The mean of the vocabulary mastery test is 68.59. it can be seen that there were 23 students who get under average scores and 14 students get a good scores over average score 73 ( Standard Minimum of Criteria).
The test was conducted in order to know the students' translation ability. The minimum score was 46 and the maximum score was 86. There were 5 students who got the score 46, 1 student who got the score 86, and 29 students who got the score lower than 75. The mean of the translation ability test is 65.38. it can be seen that there were 28 students who got score under average scores and 11 students who got the score over average score ( Standard Minimum of Criteria).
The result of the data analysis showed that value of significant generated Sig (P Value) = 0.000<α = 0.05. It means that there was correlation between two variables. In this research, the independent variable, vocabulary mastery (X) was highly influenced by dependent variable, the ability of translating (Y) and dependent variable, the translation ability (Y) was also highly influenced by the variable X.

Conclusion
After conducting the research and analyzing the data the researcher draws a conclusion as follows: There wascorrelation between students' vocabulary mastery and their translation ability at the first semester of eleventh grade of MAN 2 Bandar Lampung inthe academic year of 2017/2018 because by seeing the result of the data calculation in the previous chapter where null hypothesis ( ) was rejected, and alternative hypothesis ( ) was accepted. It means that the researcher'sassumption was revealedthat vocabulary mastery and translation ability were correlated significantly. Pearson's product moment formula by using SPSS shows the result obtained that the value of significant generated Sig.(PValue) = 0.000 < α = 0.05. It can be revealed from the hypothesis testing. Based on this research, it was concluded that a good ability in translating text, students should have mastery of vocabulary. It means that there wascorrelation between students' vocabulary mastery and their translation ability at the first semester of eleventh grade of MAN 2 Bandar Lampung in the academic of 2017/2018.

B. Suggestions
Based on the conclusion above, the researcher gave some suggestion as follows:

Suggestion for the Teacher
In this research, the researcher found out that the correlation between students' vocabulary mastery and their translation ability can be used to develop and motivate the students to master the vocabulary and ability in translating. Due the finding, the English teacher should give more attention and motivate the students to upgrade their vocabulary. The teachers also should give the input about students' work so they would know their weakness in translating text.

Suggestion for the Students
The students should study hard and more practice in learning English in order to develop their vocabulary mastery and their ability in translating because to get good ability in translation, the students have to master of vocabulary.

Suggestion for Further Researchers
For further researchers can also investigate the correlation between students' vocabulary mastery and their reading comprehension more depth to reinforce the result of this research and find out the better result.
