One of the issues of student learning is the mastery of grammar in writing skill. This can be found of student result which is still very lack of it. The condition, off course, as reflection of student result whereas still conventional and do not focus on student competence itself, how the learning should be. Generally teacher is an agent of learning at present time. This means the teacher must able to make learning become contextual involving student directly and actively. No matter how good the learning mainly is, if teacher do not able to create in delivery well, so the mainly will be not reached by student anyway. It will affect the student been bored, lack of responsibility, excitement of studying.

People are bale to write sentence without thinking about grammar they wrote. The fact is totally different because grammar is focused on the way to write it and the other side structure more focus on form of the sentence and time of the event. The time in structure know as tenses whereas the tenses show about adverb of time recognizing when an event appears, have appear, and will appear. The grammar and structure are two units cannot be separate in making of sentence. The grammar consists of subject, predicate, an object, and adverb of time, place, or manner.

The difficulties of student may be found while they learnt English grammar area. This can be happened of student result why do the student. It can thus be argued that fluency English generally – a with case, whether in grammar or writing, and the ability to understand what he or she hears and reads can be measured by learning and test which evaluate performance in language skills. Students should recognize of grammar mastery that it can be found through the writing the made. Writing can be inferred to add the knowledge about everything plus the grammar itself, how to set the paragraph, topic chosen, the language style, and the main idea. By these circumstances of learning grammar, it acquired motivation of learning in English to assist student easier in facing the difficulties of understanding the grammar. The habit of writing and understanding of grammar are those rarely comprehend by Indonesian people. This means caused by several things such as no culture-style of grammar mastery, unassisted an environment around. Writing skills have some purposes include involving the structure and grammar, raising the grammar, adding of grammar, having information of something or enjoying the literature masterpiece. In learning of language many factors should teacher noticed so purpose of the grammar mastery will be reached as well. Teacher is delivering the course can use any method of learning and also an appropriate approach based on the condition in the class and the students as well.

II. METHOD OF RESEARCH
This paper uses quantitative research method.It means the paper shown the data by using statistically form seeking an answer of problem been researched, (Kountur 2007:105).The form of X as independent variable can be viewed as a grammar while Y as dependent and represent of writing skill.The population in SMK Selagan Jaya is 47 students.Based on Arikunto references which is the sample used consisting of 20 students chosen randomly.The source of the data is taken from the result of grammar test and writing test.The research is shown the correlation between the variable of the object research.The technique of collecting data is chosen by using 20 multiple choice of grammar tests and five numbers of essay writing test.Based on the result above it said that from twenty students were found the highest score 96 and the lowest 56, from the counting result said was found an average 73,3, the median 69,5, the modus 59,91, and deviation standards 14,56.The whole data can be concluded that the data was good as a result.According to the result above it can be declared that from 20 students has 92 as the highest score and 52 as smallest score and from the resulting of calculation can be found the Mean 67,6, median 62,7, modus 60, and standard deviation 13,65.These were shown the data can be well categorized.

B. Technique of Prerequisite Data Analysis
In order to have significant and accurate data of this research, it required normality test of each variables to know whether both variable are having normal distributing.The next steps, both variables will be examined of coefficient regression and correlation.
The coefficient data is a data take from grammar and writing test.This method used to know how correlation between grammar mastery and writing skill.

Normality Test Data
The test for normality will use to know whether the data is taken from the population normal distribution or not.The criteria of normality test are H0 accepted if L count smaller than L table .This means the data of the research takes from population normal distribution.After the writer finished the calculation of normality test of grammar mastery then it was found the data shown L count has 0,23 and L table with α = 0,05 has 0,190 and α = 0,01 has 0,231.However, this can be concluded the sample was taken from normal population.Next step, it will counted of writing English test whereas found L count has 0, 09 and L table with α = 0,05 was 0,190 and α =0,01 was 0,231.It can be concluded of writing English test that the sample was taken from normal population.
The next table shows L count 0, 23 and L table with α = 0,05 is 0, 190, and α = 0,01 is 0, 231.This can be concluded the sample' source of the population is normal distribution.The table above shows L count 0, 09 and L table with α = 0,05 is 0, 190, and α = 0,01 is 0, 231.This can be concluded the sample' source of the population is normal distribution.The next steps will do test of linearity from this sample.

Linearity Regression Test
