INTRODUCTION
Human civilization is undeniable that language is a medium of interaction, an essential instrument of communication, and it is will always be used in human life (Brown, 2007;Edwards, 2009in Batubara, 2020. It is a means of communication to express the communicant message to the opposite speech. Through it, a persona can tell something or meaning to other parties, such as an idea, feeling, thinking, opinion, and more information. There are various languages globally. One of the most popular languages in the world community is English, an international language used in substantial aspects of the world's citizens, such as politics, education, economic, social, religious, and multiform other sectors. (Print ISSN 2528-1402, Online ISSN 2549 Muhammad Hasyimsyah Batubara,Delfia Herwanis,Dharma | 302 In our country, the English language is becoming from junior high school to university. To carry out the process of learning English, one of the skills mastered is reading ability. Reading is the process of understanding a written text, and it is an activity to get advantages like knowledge, vocabulary, and new information. It is a process to grasp a written text and experience in our daily activities from the text. Next, McEntire (2003); Klingner et al. (2007), it is the process of previous readers' knowledge to understand the text. Inline, Murphy (1997) mentions that reading is a process of extracting a message through a text constructed by the writer using orthographic symbols.
Views the importance of the position of reading ability in learning English, requires students to master it. However, in the case that the researcher found, the students have difficulties in reading, the problem of reading comprehension is that students feel doubtful and sometimes do not dare to read the text in English because they are afraid to get wrong to read, and students felt read text in English was very difficult, and many students were confused and noisy in the class because they felt bored read in English. So it is expected that teachers support the learning and teaching activity, specifically in teaching reading comprehension. The teacher should make learning and teaching reading interesting, enjoyable and quickly comprehend the text by using an appropriate strategy.
As revealed by McNamara (2009), an effective way to understand the text as a whole is to use a reading strategy.
There are various strategies to teach reading comprehension, such as The OK5R strategy. Based on the problem above, the writer hopes students can read well and understand reading comprehension through an OK5R strategy that positively affects students' performance in reading comprehension at tenth-grade students SMA N 15 Takengon Binaan Nenggeri Antara.

Reading Comprehension
Reading has a significant role in education. The learning process's education system demands good reading skills, with fluent reading skills showing general intellectual indicators. According to  stated that reading is an exercise that is Jurnal As-Salam Vol. 4 No. 2 Juli -Desember 2020: 301 -317 Muhammad Hasyimsyah Batubara, Delfia Herwanis, Dharma | 303 predominantly and focuses on the eyes and brain. At the same time, Demirel (1999); Kırkkılıç, Külekçi, and Gündüz (1999) mentioned reading is an act or activity to deduce written symbols with the help and cooperation of cognitive behaviour and psychomotor abilities (the mind's effort, the eyes and speech organs). Furthermore, Nunan (1989); Tarigan (1990:7); Nuttal (1996); Day and Bamford (1998:12); Grellet (1998); Cline et al. (2006: 2); Harmer (2007: 99) said reading is a process and procedure of construction or deciphering image or sign, working from a smaller unit to larger, in other words, reading is techniques to unravel composed words structures to touch, carried or base importance information.
Another explanation disclosed reading is the process of seeing, perceiving, and capture a text with its words, clause, sentences, punctuation marks, and other supporting elements to conclude a written or printed message (Göğüş, 1978;Oğuzkan, 1987;Kavcar, Oğuzkan, and Sever, 1997;Day and Bamford, 1998;Arıcı, 2008In Muhittin, 2019. After this, Scanlon (2010) uttered that reading is a complex process requiring the coordination, analysis, and interpretation of various information sources. Moreover, Snow (2002) reading simultaneously extracts and constructs meaning through interaction and written language involvement.
The explanation above shows that reading skill is an obligatory skill, especially for students expected to master it well. According to Lems et al. (2010), uttered reading comprehension can construct meaning from a given written text. Furthermore, reading comprehension can use it as a skill to identify, understand, and apply written material information (Olson and Diller, 1982:42). This argument is reinforced by Harris and Sipay (1980: 179) that reading comprehension skills are general knowledge skills that allow people to obtain and show information obtained from reading printed language.

OK5R Strategy
The OK5R strategy is developed by Walter Pauk; it is consists of 7 steps overview, key ideas, read, record, recite, review, reflect (Istarani et al., 2017). According to Sumbye (2006); Congos (2017), the OK5R strategy procedure is as follows the table. Make minor notes and highlight keywords and phrases. Question the text. Make sure all notes are in your own words.
After Reading 1. Recite so that you do not forget! a. Cover the details. b. In your own words, recite out loud the details of that main idea. It is the right way of moving information from short-term memory to long-term memory. c. Check for accuracy. d. Read, record, recite paragraph by paragraph until all material is covered. 2. Review several times each week by reciting aloud. This activity also moves information from short-term memory to long-term memory each time do it. 3. Reflect a. Think about the ideas: Consider them, compare them, notice where they agree and disagree. b. Organize it is into broader categories, or reduce it is into smaller units.
Test yourself often, especially leading up to a test.

Research Design
This study uses the quantitative method. It is called the traditional method because it has been used for a long time to become a research method. According to Sugiono (2015), quantitative methods are used because of research data in numbers and analysis The Technique of Collecting Data In this study, data collection techniques were carried out by observation and tests.

Observation
Observation is a note made by observing students involved and playing a role in literacy activities (Frank, 2010). In this case, the researcher will collect information by looking at student activity during the study.

Test
The test is a question or practice, and the other tools used to know the individual or group's intelligence, understanding, or ability (Arikunto, 2006). There are two test patterns that researchers use in this research, namely pre-test and post-test.

Validity and Reliability Test
To calculate the validity of this study, the authors used the formula from Arikunto (2013) as follows: Explanations: Rxy = The correlation of the scores on two halves of the test N = The number of students in each group X = The score of each component of reading scoring Y = The sum of all reading score ∑x = The sum of total x score in each group ∑y = The sum of the total score from each student ∑xy = The sum of multiple scores from each student with the total score ∑x2 = The sum of the square score in each component of reading ∑y2 = The sum of all reading score square

Data Analysis
This study has several stages of analyzing the data results of observations. The researcher uses the formula from Arikunto (2007)

Criteria of Succes
The criterion of this school, especially in English subject is 70, with this KKM, the test of students will know they are a success or not.

The Result of Observation
In this research, the first step that the researcher did was the observation. The observation concentrated on finding out students' conditions at SMA N 15 Takengon Binaan Nenggeri Antara and the school condition. The observation was conducted on September 04 th, 2019. The observation was concerned with finding out the school condition's information and recommending research implementation. The researcher obtained observations such as the condition and teacher strategy for teaching students in reading. Besides that student's learning condition, the researcher also got the students' data and other things to support the research.
In this research, the observation also concentrated on student performance in reading comprehension and their competency to find out the information based on their text. The observation was to determine the difficulties that the student faced before implementing teaching reading comprehension by applying the OK5R strategy. The table below explains the observation result. Based on these findings, the researcher concluded that reading comprehension is still in the low category. So, the researcher tough it was essential to use the superior strategy in reading comprehension. This study will be tested with an OK5R strategy to increase students' reading comprehension competency at SMA N 15 Takengon Binaan Nenggeri Antara.

The Result of Test
After getting the data from tests, the researcher analyzed the data by using put the row score in the table, and it could see as follow: 1. The Result Control Class The data above showed that the pre-test scores are 960, and the post-test score is 1182. Meanwhile, the average of the pre-test is 48, and the post-test is 59. Conclusions drawn from the pre-test and post-test in the control class are not satisfactory, and a few of the learners in the control class got an OK score than in the pre-test. The information above concluded that the students' pre-test score was 1144, and the post-test score was 1536. Hence deviation was 444, and the square deviation 11688, and the students' average pre-test score was 57, and the students' average post-test score was 77.

The Result Experimental Class
Whereas the formula below use to determine the standard deviation score in the experimental class.
Jurnal As-Salam Vol. 4 No. 2 Juli -Desember 2020: 301 -317 Muhammad The formula computing t-test is as follow: Based on the researcher's observation and from the research result, the researcher found that applying overview, key ideas, read, record, recite, review, reflect (OK5R) strategy to the learners can affect students' reading comprehension in descriptive form.

Testing Hypothesis
Hypothesis testing must be done to determine accepted or rejected. In this proof, the degrees of freedom (df) are sought using the following formula:

Discussion
Reading is a complex system, deriving meaning from writing that requires all skills and knowledge to understand it. Reading comprehension is getting information from the text passively and processing it in mind to take its meaning. Because of that, the students had a technique that will help them in reading comprehension. OK5R strategy is the one that can help the students be active in reading, and this strategy can help students determine the purpose of reading.
After the researcher implemented the OK5R strategy in reading comprehension, the investigator got data. It showed there several improvements from the student's result test.
Most students are given attention to the researcher's explanation and could accomplish the task well.
