I. Introduction
Physical education is one of the subjects taught in schools to improve motor development, knowledge, and the formation of attitudes such as sportsmanship, courtesy, confidence, courage, and others. According to Husdarta (2009: 3) explains that the notion of physical education is an educational process that utilizes physical and health activities to produce holistic changes in individual quality, both physically, mentally and emotionally. In addition, physical education also provides opportunities for students to be directly involved in various learning experiences through systematic physical activities, playing and exercising.
In general secondary education units that serve students with special needs, of course, require special handling in providing the learning process. Seeing the current development

Abstract
The implementation of physical education, sports and health learning on the long jump subject has problems because the motion education model used is still the same as for regular students. The difficulties have an impact on their activities which tend to be pa ssive, so a module is needed that is in accordance with the abilities and characteristics of students with mental disabilities. The purpose of this research is to produce a long jump module product through a game approach to improve basic motion in students with mental disabilities.

The method used in this research is research and development using the Research & Development (R & D) development model from Borg and Gall. To develop a long jump educational model for mental
disabilities with the aim of improving the basic locomotor, nonlocomotor, and manipulative motion patterns. Prior to the implementation stage, 2 (two) people who are competent in the field of learning physical education for children with special needs are validated. Field trials consist of trial I and trial II. Limited trials were conducted at SMPN 28 Surabaya. Then, the evaluation stage is carried out by discussing with related parties in each school after the trial / implementation.The results of the analysis of the development of the long jump motion education model in the form of a long jump learning module through the game approach were carried out very well, and were feasible in the learning process with the results of two material validation experts 77% while the design validation obtained a score of 85%. The improvement of the basic long jump movement pattern is well done.
Keywords educational models of movement; long jump; game approach; basic movement of long jump; grahita disability and observing the number of students with special needs who are entering public schools, it can be believed that from year to year the number of children with special needs in Indonesia is increasing. Facing situations and conditions like this as educators in the world of education, we should not despair because we have a collective obligation to continue to raise and educate them in the community and school, as mandated by the law, every citizen has the same right to get an education.
The physical education curriculum for Junior High Schools (SMP), as written in the Basic Competency and Basic Competency Standards (SKKD) of the education curriculum and observing the teaching and learning process (PBM) of physical education carried out at SMP that provides Inclusive Education today is actually not too different from The learning process carried out in schools in general, however, because the situations and conditions of students are different from normal children in general, PBM which is carried out in the SMP that provide Inclusive Education tends to be adjusted. It cannot be denied that the success and quality of education is determined by several factors, including the teaching staff. Because they are considered as one of the most influential parts of the success and quality of education, teachers are considered the people most responsible for the process and quality of education. For that we need a strong teacher who can anticipate teaching and learning situations in school. School provides a series of material to educate a student to adulthood, including his development. Good education must be able to meet the needs of a good learning process, which is learner-centered. Students must be active and feel comfortable when participating in the learning designed by the teacher. So that students are able to express their creativity in learning.
In the learning process students can carry out the material taught in accordance with the conditions of students. Educational services meet the needs of physical, mental, emotional and social conditions. These conditions will be more visible in education services for students with special needs (PDBK), especially for children with mental disabilities. In physical education, there are many sports included in it, one of which is athletics. Athletics is a physical activity consisting of walking, running, jumping and throwing. One of the basic competencies in physical education that must be given to junior high school students is practicing a specific combination of walking, running, jumping and throwing in a variety of simple and / or traditional games (Permenpan No. 37 of 2018).
Long jump is a movement of lifting the body from one point to another with one foot and landing on both feet to produce the farthest jump. The long jump movement begins with running then refuses on the pedestal using one leg then floats in the air and finally lands using two feet. According to Yoyo (2005: 12), to get a long jump can be done by starting as fast as possible in a controlled speed "maximum controllable speed", followed by strong and high repulsion, hovering and landing perfectly. When refusing, lean forward slightly to get the parabolic trajectory as it drifts further forward.
The reality in the field when learning the long jump is that there are still many students who hesitate when making the start and repulsion when jumping, and there are still many students who do not understand the basic long jump skills, especially mentally retarded students, so the jump results are not optimal. Children with special needs with mental retardation disorders have limitations in understanding commands and motor movements that require coordination. This is in line with Choate's (2013: 33) opinion that students who are identified as having mental blocks need a lot of repetition to master concepts and skills.
The data held at SMPN 28 Surabaya every year shows that students with mental disabilities have increased every year. In the 2018/2019 school year there were 20 students, the 2019/2020 school year there were 28 students, and the 2020/2021 school year showed an increase in the number of students with disabilities by 35 children. Seeing the increasing number of students with mental disabilities, it requires an educational model that is in accordance with the development and characteristics seen from the intellectual and motor limitations that each individual has. Because of these limitations, an education needs creativity and innovation to create a model of motion education through games that can improve the basic movements of students with mental disabilities. The aim of this research is to produce a long jump module product through a game approach to improve basic movements in students with mental disabilities.
Based on the description above, the authors are interested in conducting research with the title "Development of a Long Jump Education Model Through a Game Approach to Improve Basic Movement for Students with Grahita Disabilities in Inclusive Schools at SMP Negeri 28 Surabaya."

II. Research Methods
This research is a type of research and development (R&D) because it aims to develop a long jump motion education model to improve the basic movement skills of mentally retarded students. According to Sugiyono (2012: 407) research and development is a research method used to produce certain products and test the effectiveness of these products. Sukmadinata (2006: 169) defines research and development as a research approach to produce new products or improve existing products. So development research is a method for producing certain products.
The development model used as a reference is the Borg and Gall (1983) development model. Researchers conducted research and development of learning models in the form of long jump learning model guidelines for mental retardation in physical education subjects. Referring to the opinion of Mulyatiningsih (2013: 161) states that research and development aims to produce new products through the development process. Research and development products in education can be in the form of models, media, tools, books, modules, evaluation tools, and learning tools such as curriculum and school policies. As for the feasibility level of the learning model in the form of long jump learning guidelines for mental retardation in physical education subjects. This is known through validation by material experts, validation by media experts, validation by teachers and trial use by students.
The procedure for developing a long jump learning model for mentally retarded students can be seen in the following chart:

III. Discussion
