The vocabulary size for SMAN 2 Bandar Lampung is 5340 words, while 4130 words for SMAN 1 Sumberejo. There is a difference of SMAN 2 Bandar Lampung vocabulary size with the study conducted by Afriando .

U-JET. Vol 12. No 3, 2023 According to the result SMA Al-Kautsar passed the curriculum requirement with the score of However. SMA Muhammadiyah Gisting did not fulfill the curriculum requirement. The positive perception towards the statement of English as favorite subject was found in this research as most of the students of SMA Al-Kautsar were chose option 1 and 2. The statement of the way the students are enjoying their teacher teaches or not found to have positive statement similar with previous case. The knowledge as the external factors of studentsAo perception also indicated contributing on studentsAo vocabulary mastery difference, as the study found the different amount of students who are join English course or not. The vocabulary size of State SMP students in Bandar Lampung and Tanggamus The vocabulary size of SMPN 22 Bandar Lampung is 4054 words, which is higher than the vocabulary size average of SMPN 1 Gisting that is 3221 words. The external factors of perception which is knowledge, found to be a factor that differ students vocabulary mastery. Similar with previous case, there are big difference number between the students who participate in English course and those who did not participate. As much as 11 students of SMPN 22 Bandar Lampung were joining English course, while only 2 students of SMPN 1 Gisting who were taking English course. The previous study conducted by Novianti . stated that there is no difference of vocabulary size between students who take English course and those who had not. However, the study revealed that there is a possibility of studentsAo vocabulary size difference regarding their participation in English course. The vocabulary size of Private SMP students in Bandar Lampung and Tanggamus The vocabulary size of Private SMP in Bandar Lampung and Tanggamus seems to looks very SMP 1 Muhammadiyah Gisting only got 2910 words, which means lower. On the flip side. SMP Al-Kautsar got 4275 words that also categorized as the biggest from all SMP that participated in this research. The factor that probably causes SMP Muhammadiyah 1 Gisting students to have lower vocabulary size is the participation in English course. Out of 30 students, only 1 student who was joined an English course. On the contrary, the amount of students in SMP Al-Kautsar who join English course is bigger than who not join. 16 students were stated yes, and 12 students were stated no with the statement whether they are participating in an English course or not. It means that the external factor of perception . may contribute to the difference of student vocabulary mastery. The students joined English course seems to have high score. Again, the study proved that there is difference vocabulary size between the students who participate in English course and those who did not participate. SMP Al-Kautsar shows positive perceptions towards the statement whether they are enjoy with their teachersAo way in teaching as most of the students were chose option 1 and 2. The vocabulary size of State and Private SMA students in Bandar Lampung The vocabulary size of SMAN 2 Bandar Lampung and SMA Al-Kautsar Bandar Lampung was slightly different. SMAN 2 Bandar Lampung got 5340 which is bigger than SMA Al-Kautsar Bandar Lampung who got 5027. In the study conducted by Afriando . SMAN 2 Bandar Lampung also got the highest vocabulary size compared to other schools in Bandar Lampung. Both of SMAN 2 Bandar Lampung and SMA Al-Kautsar showed positive perception toward the statements of English as favorite subject and their perception to their English teacher way The vocabulary size of State and Private SMA students in Tanggamus SMAN 1 Sumberejo seems to have more vocabulary size than SMA Muhammadiyah Gisting. SMAN 1 Sumberejo got 4130, while SMA Muhammadiyah Gisting got 3801. Referring to the U-JET. Vol 12. No 3, 2023 curriculum. SMA Muhammadiyah cannot fulfill the curriculum requirement since the size of the vocabulary is still below 4000 words. The vocabulary size of State and Private SMP students in Bandar Lampung SMP Al-Kautsar got 4275 in the vocabulary size test which is bigger than SMP 22 Bandar Lampung that got 4054. Generally, state school is assumed as superior school rather than private However, the result proved that private school can be more superior to state school. Therefore, there should be a further research to prove the statement above. Both of SMP 22 and SMP Al-Kautsar showed positive perception toward the statement of whether the students are enjoying the way their teacher teaches. This may be related to the results of the vocabulary mastery scores from the two schools which were higher than the other two schools. The vocabulary size of State and Private SMP students in Tanggamus SMPN 1 Gisting got 3221 in the vocabulary size test. It was quietly bigger than SMP Muhammadiyah Gisting that got 2910 words. There are assumption that state school is has better performance rather than private school. According to the result above, the assumption is proved. Another factor that influences studentsAo vocabulary size is studentsAo perception toward their English teacher. The study revealed as much as 16 students of SMP Muhammadiyah 1 Gisting stated the way their English teacher teach is less pleasant, 11 students stated pleasant, and the rest of 3 students stated very pleasant. In the other side. SMP Al-Kautsar showed positive perception with the statement of the way their English teacher teaches. It implies that the teacher plays an important role in studentsAo vocabulary size enhancement. Therefore, improving or modifying the learning activity can be done in order to make significant improvement on studentsAo vocabulary size. IV. CONCLUSIONS AND SUGGESTION Based on the results of the data analysis and discussion, the researcher would like to conclude as State & Private Schools There is an assumption stated state school is better than private school. However, the research found that the private school (SMP Al-Kautsar Bandar Lampun. got the highest score of vocabulary size, beating two state schools. Therefore, it can be conclude that private school can has good performance rather than state school, obviously with the support of several factors like learning facility, effective teaching method, friendly school environment, etc. Bandar Lampung & Tanggamus Schools Schools in Bandar Lampung as a school located in urban area are assumed to have good performance rather than non-urban area schools which are Tanggamus schools. As what have been found on the study. SMAN 2 Bandar Lampung got the highest score of vocabulary size among all of the SMAAos schools included in the research, followed by SMA Al-Kautsar Bandar Lampung in the second place. Meanwhile, in the level of SMP. SMP Al-Kautsar is the school who got the highest score of vocabulary size followed by SMPN 22 Bandar Lampung. One of the factors that influence studentAos vocabulary size in urban and non-urban area is the facility in learning English. The students in urban area tend to have more access to various facility rather than the students in non-urban area. Apart from that, the study found that the participation in English course of the students in non-urban area is lower than the students in urban area. The lower participation of English course may cause by the least number of English language course institutions in non-urban area and the lack of student interest in taking English U-JET. Vol 12. No 3, 2023 Suggestions are given to the participants who are closely related to this research. The suggestions are made based on the conclusions of this research. They are presented as follows: For teachers Based on the analysis of the result, it was found that there are some students that do not feel pleasant with the way the English teacher teaches. Considering those finding, the English teachers suggested to upgrade or modify the teaching styles or visualize the materials in case to make the students fully engaged in learning activity. For further researchers The research still needed further improvement. For further researchers who want to conduct related to the recent research are suggested to add more level of the vocabulary size in order to know how wide the vocabulary mastered by the students. Another suggestion for further researcher is involving more participants to give more variation of the data. REFERENCES
