Keywords : Course Review Horay, Math Learning Stake, Ability Solution To Math Problem, Adobe Flash INTRODUCTIONS According to Kartana (2014), education is a conscious and planned effort to create an atmosphere of learning and learning process so that students actively develop their potential. Education is also believed to be a process of changing behavior in individuals, groups and organizations. The low quality of education at every level of education is a problem faced by the Indonesian people. Various attempts have been made, one of which is curriculum development, improvement of teacher competency, education management, use of media and teaching aids that are more maximized. One of the subjects taught to students in schools is mathematics. According to Faz (2017), Mathematics is one of the subjects taught in schools since Elementary School (SD) or even preschool. Therefore, students should be familiar and love mathematics. Mathematics occupies an important role in the world of education, where mathematics is a subject that is the basis for other sciences so that mathematics is very important to learn. But in reality, many students find it difficult to complete mathematics so that not a few students who get grades are less satisfying. This can occur because interactions in the learning process are dominated by teachers which results in passive, non-creative and unmotivated students (Amaliyakh & Isnani, 2015). Talang 1 Junior High School is a school that applies the 2013 curriculum so that the learning model implemented is in accordance with the 2013 curriculum, which is the cooperative learning model. According to Ms. Nurfita Rosmida S.Pd as a grade VIII mathematics teacher, some students were indifferent, had little interest in learning mailto:finachilmi315@gmail.com mailto:ibnusinaupstegal@gmail.com mailto:wikan.piti@gmail.com 90 Mathematics Education Journals Vol. 3 No. 2 August 2019 ISSN : 2579-5724 ISSN : 2579-5260 (Online) http://ejournal.umm.ac.id/index.php/MEJ mathematics especially to read the material being studied and still liked to play with other friends so they paid less attention to learning. Therefore, in the learning process sometimes teachers still use conventional learning models and questions and answers. The teacher also states that when students are given question exercises, the teacher must appoint students to work forward because that way students want to work on the questions given and only 2 to 3 students who dare to come forward to solve the problem. Slameto (2010), states that interest is a sense of preferability and a sense of attachment to a thing or activity, without anyone asking. Thus the statement of the mathematics teacher at SMP Negeri 1 Talang which states that students must be appointed to move forward in order to work on the given problem, can be said that students' interest in learning mathematics is low. This is also shown from the average score below the Minimum Mastery Criteria (KKM) and only 26% of students who exceeded the KKM is 70 at the Odd End of Semester (PAS) school year 2018/2019. One of the goals of learning mathematics is understanding mathematical concepts, explaining the interrelationships between concepts or algorithms flexibly, accurately, efficiently and precisely in problem solving (Duha, 2012). Based on the purpose of learning mathematics, problem solving skills become an important component that must be possessed in learning. This is reinforced by Husna (Simanungkalit, 2016), that the ability to solve problems is something that is very important for students to have in achieving the curriculum. Furthermore (Anisa, 2014), that learning mathematics if successful, among others, will produce students who have problem-solving abilities, communication skills, reasoning abilities, understanding abilities and other abilities well and are able to take advantage of the usefulness of mathematics in life. Based on the results of an interview with Ms. Diah Ekawati S.Pd as a mathematics teacher in class VIII, that the ability of students in SMP Negeri 1 Talang is classified as heterogeneous due to the influence of zoning on student acceptance. In addition, there are still many students who have difficulty in solving problems that are not routine, especially a matter of stories where students do not understand the problem so that it is not right in making plans that will be applied in solving problems that result in incorrect answers. The cube and the block are the material that class VIII students learn in the even semester. Based on the results of Nurmavia's research (2011), that one of the difficulties experienced by students in learning the material of flat side space is: difficulty understanding and using the concept of comparison between volume and surface area. In addition, Ms. Nurfita Rosmida S.Pd said that students had difficulty in imagining a hollow cube so that it was difficult to understand the concepts taught and the material had been studied in elementary schools where students lacked understanding of the material of the cube and blocks which caused the students to be bored and not likes to relearn, which in the end the learning achievement on geometry material becomes low. This is what underlies the selection of cubes and beams as material to be studied. One way to overcome these problems is to use the Course Review Horay learning model because the Course Review Horay learning model can create a lively classroom atmosphere and can help students understand concepts well through group discussions (Eliyah, Isnani and Utami, 2018). Course Review Horay learning model is a learning model that requires the cooperation of students with other students to solve problems in which there is a test of students' understanding of concepts in solving problems by means of answers to questions written on cards that have been equipped 91 Mathematics Education Journals Vol. 3 No. 2 August 2019 ISSN : 2579-5724 ISSN : 2579-5260 (Online) http://ejournal.umm.ac.id/index.php/MEJ with numbers so as to create a classroom atmosphere fun that can make students active in the learning process because every group that gets the right sign must shout "horay" or yells that have been determined by the group beforehand. In the process of learning mathematics often learning media are needed in order to make it easier for teachers to deliver material to students. However, according to Ms. Diah Ekawati S.Pd the media used in learning are only modules without utilizing computer-related media even though the facility is in school. Therefore, the use of Adobe Flash learning media is one alternative to facilitate students in understanding the concept of cubes and blocks which of course with interactive elements. This is reinforced by Darari (2017), that Adobe Flash media can improve problem solving abilities and motivation of high students. According to previous research conducted by 1) Risma Nurul Auliya (2013), it was found that there was an increase in students' mathematics learning achievement taught by the Caurse Review Horay type cooperative learning model. 2) Amelia, F., & Siahaan, F. H. (2016) found that the CRH learning model was effective in terms of student mathematics learning outcomes on the subject matter of prism and pyramid spaces in class VIII of Laksamana Middle School Batam. 3) Eliyah (2018), the results show that the confidence and mathematics learning achievement of students taught using the Course Review Horay learning model assisted by Microsoft Power Point is better than those taught using conventional learning models. In contrast to previous studies, this study uses Adobe Flash learning media. The use of Adobe Flash as a learning medium is useful for teachers to prepare teaching materials and can be used as aids in the teaching and learning process. Adobe Flash media can stimulate students' stimulus to be able to manipulate existing concepts and can find out the real form of abstract mathematical concepts (Umam and Yudi, 2016). Based on the problem that has been explained in the results of an interview with one of the teachers in SMP Negeri 1 Talang and the results of the existing research, in this study further research will be conducted under the title "The Effectiveness of Adobe Flash Assisted Course Review Horay Assistance for Interest and Mathematical Problem Solving Ability (Research Study on Class VIII Students in Semester II Middle School 1 Talang, Tegal Regency, 2018/2019 Academic Year on Cubes and Beams) ". The objectives of this study are: 1) Describe whether the mathematical problem solving abilities of students taught using the Adobe Flash Course Review Horay learning model whose value is above 70 exceeds 53.125%, 2) Describe whether the learning interest of students taught using the Course Review Horay learning model Adobe Flash- assisted is better than students taught using the Course Review horay learning model, 3) Describe the mathematical problem solving ability of students taught using the Course Review Horay learning model Adobe Flash-assisted better than students taught using the Course Review Horay learning model , 4) Describe whether there are differences in interest in learning mathematics and the ability to solve mathematical problems between students taught using the Adobe Flash Course Review learning model assisted by Adobe Flash and students taught using the p model Course Review Horay learning, 5) Describe interest in learning mathematics and mathematics problem solving skills of students taught using Adobe Flash Course Review Horay learning models better than students taught using the Course Review Horay learning model 92 Mathematics Education Journals Vol. 3 No. 2 August 2019 ISSN : 2579-5724 ISSN : 2579-5260 (Online) http://ejournal.umm.ac.id/index.php/MEJ RESEARCH METHOD The approach used in this study is a quantitative approach because the data obtained in the form of numbers and allows the use of statistical data analysis techniques. The population used was all students of class VIII SMP 1 Talang odd semester 2018/2019 consisting of 9 classes with a total of 288 students. In this study the sample to be used consisted of 3 classes with a total of 96 students. The sampling technique was Cluster Random Sampling obtained by class VIII C as the experimental class I, class VIII F as the experimental class II, and class VIII A as the experimental class. Data collection techniques used were documentation, mathematics interest questionnaire and mathematics problem solving ability tests. In the data analysis technique there are 2 stages. First, before conducting the research, the analysis prerequisite test is carried out first, namely the sample equivalence test consisting of normality test, homogeneity test and one-way anova test. Then the instrument of mathematical problem solving ability test is performed which consists of validity, reliability, different power and difficulty levels. The second step is testing the hypothesis. Before a hypothesis test is performed, a prerequisite test is carried out, ie univariate normality and homogeneity tests as a condition in calculating the Right - Handed One-t-Test. After the data is normally distributed and univariate homogeneous, the Right-Party One-tailed Test can be performed. In addition, the Manova Test requirements in the calculation must be normally distributed and homogeneous. In this study the normality and homogeneity tests used are multivariate normality and homogeneity tests. After the data is normally distributed and multivariate homogeneous, the Manova Test can be performed. Then, proceed with the hypothesis test consisting of the Right-Party Proportion Test, Right-Party One-t Test, Manova Test, and Hotelling Test. RESULTS This research was conducted at Talang 1 Junior High School, located on Jl. Projosumarto II No. 11 Talang District, Tegal Regency which took place on 18 March 2019 until 20 April 2019 during 5 meetings with materials of cubes and blocks. The sample in this study consisted of 3 classes, namely the experimental class (VIII A), the experimental class I (VIII C) and the experimental class II (VIII F) with 96 students. Of the three classes having equal ability, this is evident from the grades obtained by students in the Final Assessment Semester (PAS) odd mathematics subjects in class VIII of SMP Negeri 1 Talang in the academic year 2018/2019.

Based on the results of research conducted at Talang 1 Junior High School in class VIII students in semester II of the 2018/2019 academic year on cube and beam material shows that the mathematical problem solving ability taught by the Adobe Flash Course Review Horay learning model reaches the target. This is because in learning Course Review Horay aided by Adobe Flash the teacher facilitates students in making summaries, directing, and giving confirmation on the material that has been learned which of course with interactive elements. This is in accordance with Darari (2017: 40), that Adobe Flash media can improve problem solving abilities and motivation of high students. Based on the results of research interest in learning mathematics and mathematical problem solving skills taught using the Adobe Flash Caurse Review Horay learning model is better than those taught using the Caurse Review Horay learning model. This is because the Course Review Horay learning model is a learning model that requires the cooperation of students with other students to solve problems from the problems that have been given by interspersed with entertainment that makes the atmosphere not tense. That way students are more eager to participate in learning and can generate interest in learning mathematics. In addition, the addition of learning media in the form of Adobe Flash media during the learning process can also create a more interesting learning 97 Mathematics Education Journals Vol. 3 No. 2 August 2019 ISSN : 2579-5724 ISSN : 2579-5260 (Online) http://ejournal.umm.ac.id/index.php/MEJ atmosphere and make it easier for students to understand the concept of cubes and blocks. Based on the results of the study there is a difference between interest in learning mathematics and the ability to solve mathematical problems taught by the Adobe Flash Caurse Review Horay learning model and those taught by the Caurse Review Horay learning model. This is because of the different stages of learning in each learning model that is applied where in the experimental class I the addition of learning media. Adobe Flash Caurse Review assisted aims to increase interest in learning mathematics. With a high interest in learning mathematics, the learning process will go well so that students in learning do not get bored easily, can concentrate, easy to remember the material being learned and easy to communicate with other students who will eventually be excited if given a problem to find solutions to these solutions. That way students will be easier to solve a given problem. Based on the results of research interest in learning mathematics and mathematical problem solving skills taught using the Adobe Flash Caurse Review Horay learning model is better than those taught using the Caurse Review Horay learning model. This is in accordance with Eliyah, Isnani and Utami (2018: 132) that the Course Review Horay learning model can create a lively classroom atmosphere and can help students understand concepts well through group discussions. In addition, it is also in line with Umam and Yudi (2016: 86) that Adobe Flash media can stimulate students' stimulus so that they can manipulate existing concepts and can find out the real form of abstract mathematical concepts. That way, students have no difficulty in understanding the material of cubes and blocks. According to Sholikhakh, et al (2019: 33-39), effectiveness in the learning model is the result obtained from the learning process, which is good in completing the KKM, using a better model, and there are differences from the model with the previous model. Based on the results of research conducted, it can be concluded that the learning model of Adobe Flash Caurse Review is more effective than the learning model of Caurse Review Horay on cube and beam material. CONCLUSION Based on the results of data analysis and the results of the discussion in a study conducted on students of class VIII Semester II Middle School 1 Talang Academic Year 2018/2019, the following conclusions are obtained: 1. Mathematical problem-solving abilities of students taught using the Adobe Flash Course Review Horay learning model whose scores are above 70 exceeds 53.125%. 2. The interest in learning mathematics of students taught using the Course Review Horay learning model assisted by Adobe Flash is better than students who are taught using the Course Review Horay learning model. 3. Mathematical problem-solving abilities of students taught using the Adobe Flash Course Review Horay learning model are better than those of students taught using the Course Review Horay learning model. 4. There is a difference between the interest in learning mathematics and the ability to solve mathematical problems of students who are taught using the Adobe Flash Caurse Review Horay learning model and students who are taught using the Caurse Review Horay learning model. 98 Mathematics Education Journals Vol. 3 No. 2 August 2019 ISSN : 2579-5724 ISSN : 2579-5260 (Online) http://ejournal.umm.ac.id/index.php/MEJ 5.
