The game of football has developed into a game that is most in demand by all people in Indonesia. Football is played by two teams where the two teams are against each other with the aim of scoring goals in order to achieve victory (Alfi et al., 2019). Misbahuddin & Winarno (2020) argues that the time played in a soccer game in each half is 45 minutes long with no more than 15 minutes of rest time. Football is one of the efforts to maintain physical fitness in order to stay in good condition and fit. Football for players is a game as a team so it takes good teamwork and is supported by the abilities of each individual (Adityatama, 2017). Playing soccer can improve the skills that exist in the human body so as to make the psyche of people who play soccer happy and happy (Samsudin et al., 2020). In the game of soccer, physical fitness is needed to support the performance of athletes in achieving achievements. Factors in playing football include physical, technical, tactical, and psychological factors (Bujnovsky et al., 2019). Physical fitness is related to human activities regarding work and active actions. Physical fitness is an individual's capacity to carry out productive activities without causing excessive fatigue(Joseph, 2018). Physical fitness can be a benchmark for someone to be healthy or unhealthy (Murbawani & Firiana, 2017). Physical fitness is not only needed in sports activities, but also in living daily life.

To become a high-quality and high-achieving soccer athlete, athletes must not only master technical skills, but also must be accompanied by an adequate level of physical fitness so that each athlete can achieve the desired achievement. One way to improve fitness includes a combination of regular exercise and the abilities possessed by an athlete. Physical fitness can affect a person's condition, be it physically, mentally and mentally so that every day they can accept the workload given (Maisaroh et al., 2020). The purpose of regular exercise is to be able to maintain physical condition so as to improve physical fitness. With good conditions, individuals are in their best performance to achieve achievements. In addition to obtaining achievements, physical fitness can also improve human resources towards a healthy lifestyle (Shofan et al., 2021). Physical fitness is the capacity and ability of the body given to him so that he can make adjustments to conditions and the environment without causing excessive fatigue (Hartanti & Mawarni, 2020). Physical fitness can be in the form of physical activity, games or sports to be able to achieve certain goals (Warni et al., 2021). To be able to increase the level of physical fitness, several ways that can be done are to regulate your diet regularly, get enough rest, and do sports activities regularly (Rahmawati & Hariyanto, 2020). A healthy condition for a person is a necessity that is very helpful in supporting daily physical activities (Nursena, 2019). Athletes with adequate physical fitness status will be able to carry out training activities well (Abdurrahim & Hariadi, 2018). In order to improve physical condition, athletes can do physical exercise in a programmed and good manner so that it affects the individual and the quality of the team (Sadewa & Nurrochmah, 2020). Adequate physical ability will be able to do the job well suddenly or additionally (Fida & Candra, 2020). Doing physical fitness activities is one way to maintain physical condition (Valentino & Nurrochmah, 2020). Physical fitness tests in soccer are very important because physical fitness can affect the physical condition of athletes at SSB Satria Mandiri. Physical fitness is one of the supporting components in determining the achievement of an athlete, including in the game of football. Physical exercise programs must be well planned and programmed so that athletes can achieve good and maximum performance(Setiawan & Pamot, 2021). If the achievement of an athlete increases, then the athlete will be able to raise the name of both the region and the country (Rofik et al., 2021). Looking at the characteristics of the game of football, the elements that are required in the physical condition of the game of football include strength, endurance, speed, power, agility and other physical components (Wibowo, 2020). It can be concluded from the discussion above that some athletes at SSB Satria Mandiri are still lacking in physical fitness. According to the observations of the SSB Satria Mandiri coach, the level of physical fitness of the SSB Satria Mandiri athletes is still lacking. During the training process the coach has never held tests and measurements to find out how big the level of physical fitness in soccer athletes aged 13-15 years at SSB Satria Mandiri, Bojonegoro Regency. So that the coach does not have data on how big the level https://jse.rezkimedia.org/index.php/jse/index Nugraha, Yunus, & Widiawati – Survey on physical fitness of athletes aged 13-15 years … 115 of physical fitness in soccer athletes at SSB Satria Mandiri. It is feared that this will affect the athlete's achievement, so that the athlete is not in his best condition. In order to determine the level of physical fitness.

Physical fitness can be estimated by carrying out various tests according to the age category of the test taker. According to Hartanti & Mawarni (2020) physical fitness is the actual part of overall fitness, which allows individuals to live a productive life, without causing excessive fatigue so that they are able to perform other productive tasks. Physical fitness is the initial reference in determining the level of the athlete's physical condition. Physical fitness plays an important role for all athletes. Physical fitness in the game of soccer is very necessary for an athlete to be able to play and practice well. Athletes with a good level of physical fitness will adapt more quickly to the training given to them. Because athletes are trained and prepared to be able to achieve achievements both individually and as a team. So that a good physical fitness status is needed so that athletes can achieve their best conditions in achieving achievements. Without good physical fitness status, athletes will not be able to develop their abilities to achieve the best performance and can hinder the physical activities they will do. For adolescent athletes, the level of physical fitness of an athlete can be increased from the training process given to him. The role of the coach is also very necessary to train athletes in order to improve their physical fitness. The training method for adolescent athletes will affect the physical condition of the athlete in the future, so that the training method is of special concern to the coach in order to provide training methods that are appropriate to the age group of the students he trains. Physical factors, techniques, tactics are factors that influence the game of football in order to play well (Samsudin et al., 2020). In line with the research that has been carried out by Putra (2021) argues that to be able to complete an activity efficiently and effectively, every human being must have an adequate physical fitness status, because the level of adequate physical fitness affects mental health and also affects the achievement to be achieved. Sani & Hariadi (2020) states that physical fitness has advantages for individuals from completing optimal https://jse.rezkimedia.org/index.php/jse/index Nugraha, Yunus, & Widiawati – Survey on physical fitness of athletes aged 13-15 years … 119 work. According to Zulfa & Kurniawan (2019) someone with a high level of productivity will have a fit body condition, this can support their learning process. According to Anggita et al. (2019) physical fitness contributes a lot to student learning achievement, with an effective contribution. Opinion by Arifandy et al. (2021) a person can do physical exercise by involving various components of physical fitness and the correct training method in order to achieve excellent physical fitness. Highly qualified physical fitness will be able to do a reasonable job without reducing its quality and intensity (Prontenko et al., 2019). Physical fitness is one of the important components in obtaining the productivity of the activities carried out so as to achieve maximum results (Saputro, 2018). The more a person does exercise, and the greater the variety of activities carried out, the more fit the body will be (Sari & Nurrochmah, 2019). Research that has been carried out by Setia & Winarno (2021) concluded that the level of physical fitness of a person can be determined from the quality of the exercise used, the better the quality of the exercise used so as to achieve maximum physical condition. Research conducted by Yuliana & Sugiharto (2019) about the level of physical fitness in athletes aged 14 years at SSB Tugumuda Semarang included in the good category. While the research that has been done by Shofan et al. (2021) Regarding the survey on the physical fitness level of SSB Karlos players, Malang City aged 15 years, it is included in the less category. Based on the results of tests that have been carried out in this study, the level of physical fitness in athletes aged 13-15 years at the Satria Mandiri soccer school, Bojonegoro Regency as a whole, obtained results with criteria, very good 0 out of 22 athletes or (0%), 6 athletes received good category with percentage (27, 27%), 12 athletes got medium category with percentage (54, 54%), 4 athletes got less category with percentage (18, 18/%). Most of the physical fitness of athletes aged 13 to 15 years at SSB Satria Mandiri are in the moderate category. CONCLUSION Based on the results of the physical fitness test for SSB Satria Mandiri athletes aged 13-15 years that had been carried out, 22 athletes were the subject of the study. The data obtained by the physical fitness level of athletes aged 13 to 15 years at the Satria Mandiri soccer school as a whole did not have any test items that scored very good. Therefore, more attention is needed from the coaches at the Satria Mandiri soccer school so that they can improve the physical fitness level of the athletes and the test results are monitored regularly as material for evaluating training programs.
