Introduction
Sports activities in physical and health education are aimed at imparting the essence of sport itself in each student so that they feel the importance of carrying out movement activities. Children who do movement activities will improve their physical health and motor skills. Physical education in schools is designed in the form of games so that these activities can increase students' motivation in doing sports activities by playing various games.
https://jurnal.unimed.ac.id/2012/index.php/jpehr________________________________ Game is a activity that makes you feel funny and happy. Play is actually a boost from within the child and a necessity for the child. Traditional games provide not only recreational or fun value. More than that, traditional games also have sporting values and even social values. This is because in traditional games there are elements such as sportsmanship, honesty, accuracy, agility, accuracy in determining steps, and working together in groups. In Ismatul's research, Prasetyo and Ellya (2011: 1) found that traditional games are a means of developing basic aspects of children's development, such as: physical, cognitive, social-emotional, and language.
Permainan galah asin is a kind of regional game from Indonesia which we can still find currently being played by students in schools. Anita Lioni and Rudi Heri (2015: 5) say that permainan galah asin is a group game consisting of two groups, where each team consists of 3-5 people. The essence of the game is to block the opponent so that they cannot pass over the line to the last line back and forth, and to win all group members must complete the process back and forth in the designated area. This game will require children to be able to perform moving activities such as stopping, jumping, turning, bending, running, walking, sliding and other movements that are included in locomotor and non-locomotor motion. To complement this game with three children's motor skills, namely coupled with manipulative movements, it is necessary that this game be modified so that it is better and more meaningful for children to play because it will be able to improve their motor skills completely. The traditional namely permainan galah asin is modified in the form of a game using a ball. Where this game develops not only locomotor motion but includes manipulative motion. The purpose of this game is to improve cooperation, improve motor skills, improve fitness, improve coordination, increase self-confidence, increase the spirit of competition, improve social skills and also increase the spirit of sportsmanship. Physical education has developed into a means of therapy for children with special needs in increasing their interest and willingness to carry out activities like normal children. Physical education is proven to improve children's ability to socialize and communicate with other people. Physical education can also improve children's affective, cognitive and psychomotor abilities.
Physical education activities are carried out in schools starting from junior school level to high school level with the aim of building basic skills. Basic movement skills can be interpreted as a process to obtain motion that is constantly developing which is influenced by several things, namely: (1) the process of developing nerves and muscles which is also influenced by heredity, (2) the result PJKR_ https://jurnal.unimed.ac.id/2012/index.php/jpehr________________________________ of previous experience of motion, (3) experience of motion at this time, (4) the motion is described in relation to certain motion patterns.
To get a complete education as well as good movement skills, of course there is support from people who are close to the child. Parents are the people most often and also the closest to children so that parental support is needed in the growth and development of children both in affective, cognitive and psychological aspects. The way parents direct can be through the educational process and experiences that parents have. The attention of parents apart from support, direction and warning is also by providing a means of study and meeting learning needs to support children's learning at school and at home. This is in line with the opinion of Sutari Imam B (1995: 121), parents' attention to their children, both in the form of support and learning facilities, will affect children's success.
For children with special needs such as mentally disabled students, of course, the support of parents in their daily lives is of course very much needed. Where children are mentally retarded, so they need special attention from the surrounding environment as well as from their own parents. Mentally retarded children are children who have shortcomings or limitations in terms of mental intellectuality, below the normal average, so they experience difficulties in academic, communication, and social tasks, and require special education services, so that the education provided is special called adactive physical education. The benefits of adactive physical education according to Abdoellah A (1996: 14) are (1) developing body strength, endurance, flexibility and mobility so that they can develop optimal levels of freshness, (2) developing movement skills with creative games that help participants students develop muscle nerve coordination, (3) can develop children's emotional abilities which will respect differences and tolerate their friends, (4) can develop cognitive abilities where each game requires thinking so as to improve students' intellectual abilities.
Because of these deficiencies, mentally disabled students need special attention so they are placed in schools for children with special needs so that they can be nurtured and guided so that they can be like other normal children. Learning in schools for children with special needs is designed in such a way that it can improve children's abilities in carrying out their daily activities. In addition, games are designed to activate children's mobility, both non-locomotor, locomotor and manipulative, which are important for the growth and development of mentally retarded children. The results of research by Arif Rohman Hakim (2015: 36) which states that the motor skills of mentally retarded children can be trained through sports, namely by using the right training method. The modified salty gaff game developed in the game on physical education learning is designed to prepare Physical Education, Health and Recreation;Vol. 5, No. 1 (2020)  mentally retarded students to move actively in learning so that they can improve their abilities like normal children. Therefore, it is necessary to study how the influence of the salty pole game with the support of parents on the basic movement skills of mentally disabled students. This study aims to determine (1) To find out how the difference between modifikasi permainan galah asin is better than permainan galah asin on gross motor development of mentally disabled students (2) To find out how the interaction between permainan galah asin and parental support for basic movement skills in mentally retarded students . (3). To find out the difference between high parental support and low parental support for the basic movement skills of mentally disabled students. (4) This is to determine the difference between permainan galah asin and modifikasi permainan galah asin with high parental support for gross motor develompment.

Method
The method used in this research is the experiential method with permainan galah asin and modifikasi permainan galah asin as treatment and parental support as the moderator variable while the dependent variable is gross motor development. The sample was taken from the population with a simple random technique where this research was conducted on students with mental retardation at the junior high school level in SLB-E Negeri Pembina North Sumatra, totaling 31 students. The method used in this research is an experimental method with anova 2x2 design. Data were collected from the test instrument for parental support and basic movement skills which were tested for the validity and reliability of the test first. The data is then analyzed using two-way analysis of variance to test the hypothesis. Before using two-way analysis of variance, the data must first meet the requirements of normality and homogenity.

Result and Discussion
The results of the statistical analysis of the first hypothesis where the calculation of the difference in effectiveness between permainan galah asin and modifikasi permainan galah asin. Based on the results of the ANOVA, it can be seen that F count between columns = 4.38, is actually greater than F table , which is equal to α: 0.05: 4.26 (F count = 4.38> F Tabel (0.05) = 4.26) so that H o is rejected and H1 is accepted at the 95% significance level. Thus it can be concluded that overall there is a difference between permainan galah asin and modifikasi permainan galah asin on the basic movement skills of mentally disabled students.
The results of the second statistical analysis were to determine whether there was an interaction between permainan galah asin and the support of parents for gross motor development. Based on the summary of the results of the calculation of the analysis of variance, it is obtained that the value of the Interaction Fcount = 5.96 and it greater than the Ftable, which is equal to α: 0.05: 4.26 (Fcount = 5.96> FTabel (0.05) = 4.26 ). Ho is rejected and H1 is accepted at the In other words, it can be stated that the increase in basic movement skills is influenced by the interaction between permainan galah asin and parental support. The results of the third hypothesis statistical analysis where the calculation of the differences in gross motor development between high parental support and low parental support. Based on the summary of the results of the calculation of variance analysis, the value of Fcount between rows = 5.30 is found to be greater than the Ftable, which is equal to α: 0.05: 4.26 (Fcount = 5.30> Ftable (0.05) = 4, 26) so that Ho is rejected and H1 is accepted at the 95% significance level. Thus it can be concluded that overall there are differences in gross motor develompment between high parental support and low parental support.
The results of the fourth hypothesis analysis are to determine the difference between permainan galah asin dan permainan modifikasi galah asin with high parental support for gross motor development. Advanced analysis of variance calculations with Tuckey's test to compare high parental support groups in both groups. The results of the calculation show that the price of Qcount = 5.68 is greater than Qtable = 4.68 or Qcount> Qtable at a significant level of α 0.05, thus Ho is rejected and H1 is accepted, meaning that there is a difference between the permainan galah asin dan permainan modifikasi galah asin with high parental support for gross motor development.
Based on the research data, it was found that the average score of gross motor development in students with high parental support and doing permainan modifikasi galah asin was 74 and the low parental support group was 64.29. For the average score of gross motor development in students with high parental support and doing permainan galah asin activities was 64.71 and the low parental support group was 65.
Through play activities children can achieve physical, intellectual, emotional and social development. Physical development can be seen when playing. Intellectual development can be seen from its ability to use or take advantage of the environment.
