= 1.97 Meanwhile, the formulation below was used to determine the Standard Error
Mean of controlled class Y: SE
=
√
=
√
= 1.40 Then, the writer calculated the difference of standard error between mean of
experimental class X and mean of controlled class Y by using this formula:
SE
- =
√ =
√ =
√ = 1.83
The next step is determining t
observed:
t
o
=
–
= =
= 2.75 Finally, the writer calculated t

t
t
in significance level of 5 with degree of freedom df:
df = N
1
+ N
2
- 2 = 25+25
– 2 = 48
Based on the degree of freedom df, the writer gained the t-table by the degree of significance 5 is 1.67
3. Test of Hypotheses
To prove the hypotheses, the data obtained from the experiment class and the control class was calculated by using t-test formula with the assumption as follows:
t tt : The alternative hypothesis Ha is accepted and the null hypothesis H
is rejected. It means that the use of social networking site is effective in teaching
writing of recount text to the tenth grade students of SMA Negeri 87 Jakarta. t
tt : The alternative hypothesis Ha is rejected and the null hypothesis H is
accepted. It means that the use of social networking site is not effective in teaching writing of recount text to the tenth grade students of SMA Negeri 87
Jakarta. By comparing the values of t
o
= 2.75 and t
t
= 1.67 or 2.751.67, the writer made the conclusions of the hypothesis that t
o
is bigger than t
t
. So, the alternative hypothesis Ha is accepted and the null hypothesis H
is rejected. It means there is significance difference between the result of using social networking site in teaching
writing of recount text and without using it.
B. Data Interpretation
From the evidence above shows that the alternative hypothesis H
a
is accepted and the null hypothesis H
is rejected. Therefore, it can be said that Facebook is effective to be used as a media in writing recount text. It is in line with
the relevant previous study by Surthiwartnarueput and Wasanasomsithi, Yunus and Salehi, and Omer Eren see p. 21-22 that Facebook is an effective tool in teaching
and improving writing skill. In addition, this research is in contradict ion with Mardi’s
research result that using ICT Information and Communication Technologies is more difficult than using non-ICT.
Furthermore, the writer found advantages that can be taken from using Facebook as a media in teaching writing of recount text and those are in line with the
advantages that had been written in chapter II. By doing peer feedback in Facebook group, students were more excited in doing their tasks because they use some social
networking sites every day, students could get some input from their friends or teacher when they have posted their writing in Facebook, and they took responsibility
for their works because they have a larger audience when they used Facebook. It can be concluded that students felt comfortable by using Facebook. If students already
have a comfort zone in learning, teacher can teach the material easily. So, besides they are interested in learning about recount text and practicing their writing skill
through Facebook, they also mastered the material of recount text.

CHAPTER V CONCLUSION AND SUGGESTION
A. Conclusion
Writing in foreign language may be not as easy as writing in native language. It occurred to the students of SMA Negeri 87 Jakarta while the writer taught recount
text. Some problems are they did not know about the vocabulary and grammar rules until they did not have the idea and even the motivation in writing. Therefore, an
interesting media is needed in teaching and learning of recount text. Facebook is one of social networking site that well-known among the students. So, the writer chose it
to be used as a media of teaching and learning of recount text. After conducting an experimental research and referring to the result of the
students’ pre-test and post-test in X IIS 3 as the experimental class and X IIS 2 as the controlled class of SMAN 87 Jakarta, the writer saw there is significance
difference between the results of variable X and variable Y. It can be seen from the value of t
o
is higher than t
t
; 2.751.67. In other words, alternative hypothesis H
a
is accepted and null hypothesis H
is rejected. Moreover, the interview result showed positive response about treatment that had conducted. It proved that the experimental
class students got the advantages of the treatment. So, the use of social networking site is effective in teaching writing of recount text to the tenth grade students of SMA
Negeri 87 Jakarta.
B. Suggestion
After having concluded the result of the research, the writer would give some suggestions that might be useful for English teacher, students, other researchers, and
school, as follow: 1.
For English teacher, it is good to use or to create an interesting media for teaching and learning in order to motivate the students. One of the media is social
networking site. Besides it is interesting for them, it can decrease their anxiety in interacting with the teacher and students.
2. The writer hopes social networking sites SNS can be useful for the students.
Because it can be used not only for sharing, updating status, uploading and downloading the fun things only but also as a media of foreign language teaching
and learning. 3.
The writer needed a longer time during implementing Facebook as a media in teaching writing of recount text. Hopefully there will be further researcher that
will conduct a better research about other social networking site. 4.
For school, it can be better if the computer laboratory can be optimized for teaching and learning facilities because sometimes the teachers need to use the
internet for media of their students. So, the learning process may be not so boring.
