MEAN 75.1
Finally, based on the score of the post-test score in the cycle 2 the calculation of the implementation percentage is gained from the following
formula:
43
P = y2 – y x100
y P = 75.1
– 59.3 x 100 59.3
P = 26.6 Based on the result of the students’ vocabulary score, there was
better improvement of students’ average score from the students’ vocabulary achievement in the preliminary study to the students’
vocabulary in the second cycle. The mean score of the pretest in the preliminary study was 15.1 and the mean score of the students’ score on
the first cycle was 48.4. It means that there was 13.9 points or 26.6 of average improvement. The students’ vocabulary improvement from the
first cycle to the second cycle recapped in the following chart:

class percentage, while 5 out of 33 students 15.1 achieved bellow 70.0 of 33. It indicated that the first criterion of success which required 75 of the students
who got at the same as or above the Minimum Mastery Criterion has been achieved. The following was the table of students’ vocabulary score.
d. Reflecting
1. Students activity in making vocabulary cluster and learn from it. In this cycle 2 the researcher and the collaborator reflect about the activity
in making and keeping the vocabulary cluster. The students could use vocabulary cluster as their media in memorizing and retaining their vocabulary.
2. Discussing the Result of the Action The result from the students score in this cycle was 81.8 of the students
or 27 students got the score above the Minimum Mastery Criterion. After getting the result of the observation note and posttest 2, the
researcher and the collaborator carried out the reflection. They felt satisfaction with the result of the action. The result of the posttest 2 showed that 81.8 of the
students got the score above the Minimum Mastery Criterion – Kriteria
Ketuntasan Minimum KKM. So it has met the first criterion of success that 75 of the students must get the score above the Minimum Mastery Criterion
– Kriteria Ketuntasna Minimal KKM. Because of the satisfied result, so the
researcher and the collaborator decided to stop the action.
C. Interpretation
In this subtopic will be delivered about the interpretation the result of the research.
1. Based on the data gained from first observation before classroom action
research CAR and during the CAR. Based on the result of the students’ participation during teaching and learning process of English vocabulary
class through observation note, in observation before CAR it was the technique given by the teacher in teaching vocabulary is not interested for
students, the teacher just giving a list of vocabulary and asked them to
45
memorize individually then students could not memorize the vocabulary easily. This problem effect to another problem of students’ proficiency in
the skills of English such as their listening, speaking, reading and writing ability, if the students had a little vocabulary they could not speak fluently,
or do not understand while listening English and many others because the limitation of their vocabulary. Vocabulary is not one of the skills in
learning a language but it is the essential part of language. However, after the students learning vocabulary through
vocabulary cluster they feel enjoy and motivated to memorize and learning English. It seen from their enthusiastic and interested in the lesson whiles
the teaching learning process and the increase of their understanding and memorizing from their score.
2. Based on the data gained from the pre interview with the English teacher
indicated that the students’ vocabulary was poor because the students had some difficulty in memorizing the new word and keeping their last
vocabulary. Besides, the students, participation in English vocabulary class was not too active. Therefore, it needed to find the suitable technique in
teaching vocabulary. The researcher suggested implementing vocabulary cluster as a strategy in teaching vocabulary. After conducting the action,
the English teacher gave positive responses about the action. The English teacher felt satisfied with the improvement made by the students focus on
vocabulary score. The English teacher also motivated to use vocabulary cluster technique because it could facilitate the students in retaining their
vocabulary. 3.
Based on the result of the students’ vocabulary score, it was found out that the students’ vocabulary score was improving. It indicated that the use of
vocabulary cluster could increase and motivate to retain and enrich their vocabulary. Most of the students gained good score at the end of each
cycle. The students’ average score in preliminary study was 59.3 in the first cycle, and the average score in the first cycle was 68.9 second cycle
was 75.1.
46
D. Cycle 1 and 2
The overall finding of the research after accomplishing the classroom action research at SMP Al-Kautsar BKUI found that the good result from
implementing Cluster Technique to improve students’ vocabulary. 1.
Cycle 1
The finding of the research proved that Clustering Technique can retain students’ vocabulary. It can be seen from the improvement of the students score.
The students’ average mean score of pre-test was 59.3. And after the
implementation of Clustering Technique, the average mean score of post-test 1 cycle 1 was 68.9. It is mean that there was an improvement of students’ mean
score after implementing Clustering technique in the first cycle.
2. Cycle 2
The researcher continued to the second cycle. The mean score was 75.1. The result of the research through Clustering Technique indicated that there was
an increase in students’ vocabulary and motivated the students to retain and enrich their vocabulary, from 15.1 in the preliminary study to 81.8 in the second
cycle. The result of the second cycle passed the Minimum Mastery Criterion –
Kriteria Ketuntasan Minimal KKM 70 as the criterion of success determined.The implementation of clustering technique gradually improved
students’ vocabulary.
Some points that can be concluded from the research is Clustering Technique 1 stimulated the students to memorize and retain their vocabulary
easily and enjoy the class activities, 2 increase students’ achievement and motivation, and 3 give a good influence to their four English skills.

CHAPTER V CONCLUSION AND SUGGESTION
A. Conclusion
After conducting the research and analyzing the data in the process of teaching vocabulary through clustering technique at the second grade of SMP Al-
Kautsar BKUI Jakarta, the researcher concluded that vocabulary cluster can be alternative strategy for teacher in teaching vocabulary. It means that there is a
significant increase of students’ vocabulary achievement after being taught through clustering technique. Related to the students’ achievement, there were twenty seven
students who passed The Minimum Mastery Criterion – Kriteria Ketuntasan Minimal
KKM 70 with the improvement of students’ means score from pre-test to the post- test of the second cycle in the pre-test, there were only five students who passed the
Minimum Mastery Criterion – Kriteria Ketuntasan Minimal KKM. Meanwhile, in
the post-test of cycle one there were sixteen students who passed the Minimum Mastery Criterion
– Kriteria Ketuntasan Minimal KKM in which their mean score of vocabulary test. Next in the result of post-test in the cycle two, there gained twenty
seven students who passed the Minimum Mastery Criterion – Kriteria Ketuntasan
Minimal KKM in. So it achieved the criteria of success.
B. Suggestion
Based on the research, there are some suggestions to offer the English teacher and the other researcher based on the research findings.
Students
Vocabulary Cluster Technique is effective to improve students’ vocabulary
Vocabulary Cluster Technique can be alternative to overcome students’ boredom.
Teacher
This strategy or technique is suggested to the English teacher or other researcher who want to conduct in similar research study.
