The research method used was an associative quantitative approach using test and measurement techniques. The data analysis technique used was a path analysis approach. The population in this research was all of POPB DKI Jakarta athletes in 2021 totaling 20 people. The sampling technique used was total sampling so that the number of samples in this research was 20 people consisting of 10 women and 10 men. The skills of Dollyo Chagi Kick Taekwondo used the Dollyo Chagi Kick skills test. The balance used a modified bass test. The concentration used a concentration grid test. The instrument of eye-foot coordination used a smart speed pro coordination test. The results showed that the direct effect of variable X1 on Y = 0,243. The direct effect of variable X2 on Y = 0,567. The direct effect of variable X3 on Y = 0,378. The direct effect of variable X1 on X3 = 0,706. The direct effect of variable X2 on X3 = 0,297. The indirect effect of variable X1 on Y through X3 = 0,706 x 0,378 = 0,267. The indirect effect of variable X2 on Y through X3 = 0,297 x 0,378 = 0,113. Keywords: balance; concentration; coordination; dollyo chagi kick INTRODUCTION Taekwondo is growing rapidly and its practitioners have spread all over the world. “Taekwondo is arguably among the most important martial arts and combat sports worldwide in considering that it is an official Olympic sport practiced by several millions of athletes” (Pérez-Gutiérrez, Valdes- Badilla, Gómez-Alonso, & Gutiérrez- García, 2015). At this time, there are about eighty million people who practice the martial arts of Taekwondo in various parts of the world this day. Taekwondo matches are divided into three types: kyorugi or fighting, poomsae or moves, and kyukpa or breaking hard objects. Taekwondo is synonymous with kicks because most of the techniques used in matches are kicks. There are varied basic kicks in taekwondo, for instance; dollyo chagi (forward kick using the back of the foot from the side), ap chagi (straight forward kick), and yepo chagi (forward kick by pushing the soles of the feet towards the target). The kick of yeop chagi contributed to obtaining a relatively high mailto:reggiereginald12@gmail.com Gladi Jurnal Ilmu Keolahragaan, 12 (05), Desember- 379 Reggie Reginald, Fahmy Fachrezzy, Iwan Hermawan score of 15% and the kick of dollyo chagi became the highest contributor as much as 28% (Mansur, 2015). Furthermore, the kick of checking yeop chagi men as much as 15,96% and women as much as 10,28%, dollyo chagi men as much as 20,11% and women as much as 13,74%, and dollyo chagi men as much as 12,50% and women as much as 7,69% and the most effective for senior male taekwondo athletes kick used was dollyo chagi (Rachmahani, 2016). Based on the explanation above, the dollyo chagi kick technique is the most frequently used technique and has the greatest effectiveness for generating points during a match. Therefore, it is crucial for athletes to master this dollyo chagi kick technique. The most commonly used and highly effective base kick in kyorugi matches is dollyo chagi kick (forward kick using the back of the feet from the side) or also known as roundhouse kick (Wojtaś, Unierzyski, & Hurnik, 2017). The dollyo chagi kick is often used in daily practice and in taekwondo competitions, it has many uses and can be used to attack, defend, and counterattack opponents (Ervilha, Fernandes, Souza, & Hamill, 2020). So this kick technique occurs a lot in matches both in senior and junior classes (Tan & Krasilshchikov, 2015). The dollyo chagi kick or also known as roundhouse kick is also owned by many other martial arts branches such as kick boxing, pencak silat (sickle kick), and karate (Mawashi-Geri) (Petri, Bandow, Salb, & Witte, 2019). Defined by Ouergui et al that the roundhouse kick is the hip performs rotational movement to the side: the legs and accompanying this rotation depict a circular arc from the outside to the inside and from the vertical plane to the horizontal plane to strike the opponent on the side (Ouergui, Hssin, Franchini, Gmada, & Bouhlel, 2013). Kick technique that can generate points is a technique determined by four factors, namely; concentration, coordination, accuracy, and impact. Concentration is needed when in the match, including when going to do kick techniques, with good concentration will create good coordination between the eyes that see the opponent and all parts of the body in order to help the attack technique come out. After the technique can be successfully come out, the next factor that determines whether a point is entered or not is accuracy and impact. A technique will get points if it hits a Gladi Jurnal Ilmu Keolahragaan, 12 (05), Desember- 380 Reggie Reginald, Fahmy Fachrezzy, Iwan Hermawan legitimate target area and generate an impact on the target of the opponent’ body. Bio motor components developed in taekwondo sports include coordination, skill, speed, flexibility, muscle strength, balance, posture, power, and endurance (Tirtawirya, 2011). Balance is one of the most important bio motor components for humans. According to (Widiastuti, 2015) “Balance is the ability to maintain the posture and position of the body quickly when standing (static balance) or when doing movements (dynamic balance)”. The ability of the body to give the desired position when moving (Gürkan, 2016). Balance is the ability to maintain the body’s center of mass over its base of support (Watson, Black, Crowson, 2016). Balance is divided into two, namely static to balance the body in a place or position and dynamic is the ability to balance movements (Zilvikar, 2016). Static balance refers to the ability to maintain equilibrium in a stationary fashion, whereas dynamic balance relates to the ability to maintain balance when the body is in motion (Shim & Rose-Woodward, 2019). dynamic balance—a state in which a robust complex system will self-correct in response to imbalance (resulting from perceived variation/challenge) to maintain functional organization, or the individual and coordinated expression of balance and imbalance (Cowen, Nesti, & Cheetham, 2014). Dynamic balance also has a positive relationship with the lower body strength in adults (Shim, Harr, & Waller, 2018). Athletes must have the awareness, knowledge, and ability to control their attention to concentrate effectively. (Cox, 2011) explained that all sports really require excellent concentration to support the performance of athletes when in matches. Joaquin Dosil in (Wibowo & Gupita, 2020) stated that taekwondo is a sport of martial arts that requires psychological factors such as concentration, anticipation, emotional control, self-control, self-confidence, and fighting power. Concentration is a basic human psychological skill that is crucial to maintain mental toughness, especially in open skill sports where the environment moves quickly and constantly changes (Monsma, Perreault, & Doan 2017). Concentration refers to the orientation or focus of a person’s psychological activity on a particular object which is also one of the most Gladi Jurnal Ilmu Keolahragaan, 12 (05), Desember- 381 Reggie Reginald, Fahmy Fachrezzy, Iwan Hermawan important factor in carrying out effective learning activities (Yang, Zhao, Tian, & Xing, 2020). (Komarudin, 2015) concentration in each individual has a difference between one and the other. Concentration enables people to exclude irrelevant information and focus on things or objects that attract them (Ma & Wei, 2016). Good concentration is really needed when in taekwondo matches because it is an individual sport where an athlete must continue to fully concentrate on the entire time of the match. If the concentration is a little bit diverted then it will have a fatal impact for an athlete. The situation in martial arts especially fighting numbers is very unpredictable. The duration of one kick only lasts less than one second so it also requires good coordination at the time of its implementation, because if it takes too long in doing it then the opponent will be able to see and the opportunity to get points will be lost. Coordination is the ability to perform movements or work appropriately and efficiently. One of the vital facts of human development is its coordination movement (Sogut, 2016). Coordination states the harmonious relationship of various factors that occur in a movement (Widiastuti, 2015). Coordination is the ability of the performer to integrate types of body movement into specific patterns” (Babu & Kumar, 2014). (Astanto, 2018) stated that in coordination will result timing and accuracy. At this time, technological advances are very rapid in various fields including sports. The development of sports technology is very important to be used especially in Indonesia to increase the achievements of athletes both local and national. The development and advancement of sports technology is indispensable for the advancement of sports achievement (Syakur, Badruzaman, & Paramitha, 2017). Digital tools are able to predict and direct someone to choose the right sport and various technologies to be able to produce high-achieving athletes (Yoda, 2020). Equipment from fusion sport.inc is one of the sports equipment development companies from Australia that has been used by national sports federations from various countries, Olympic committees, and many of the world’ elite sports teams in its athlete development programs (Fusion, 2019). This equipment is equipment using a sensor that detects a movement that is Gladi Jurnal Ilmu Keolahragaan, 12 (05), Desember- 382 Reggie Reginald, Fahmy Fachrezzy, Iwan Hermawan usually used in measuring speed in running. However, in this study, this equipment will be modified and programmed to see the coordination of the eyes, the hands, and the legs. The peak achievements of various sports are achieved around the age of 14 – 25 years and the process of coaching athletes to achieve peak achievement takes approximately 6 – 10 years (Nurjaya, 2012). Thus, the orientation of sports coaching must begin at an early age, namely when they are still in elementary school. The development of the sport should be done by paying attention to the characteristic of child, the process of growth, and the development of child. Coaching athletes should be done as early as possible in order to have sufficient time to prepare for the highest achievement. Sports coaching from an early age through structured and sustainable programs and through a good concept becomes a must where from the beginning sports coaching needs to be managed well in accordance with the principles of long- term sports coaching (Rasyono, 2016). In DKI Jakarta Province has several athlete coaching posts such as PPOP, PPLM and Pelatda. In 2019, Dispora DKI Jakarta launched a new coaching program for the first time in Indonesia, namely coaching children under the age of 15 years old and continuity which was originally called PPOB (Sustainable Sports Development Program) then its name was changed to POPB (Sustainable Achievement Sports Program). Dispora collaborated with FIK UNJ to use LTAD (Long Term Athlete Development) based on sports science on the approach of this program, as well as for the selection process of the athletes, the coaches also provided expert teams such as sports doctors, sports psychologists, paramedics, and others. A Canadian achievement sports coaching expert, Dr Istvan Balyi designed and compiled the stages of sports coaching into a clear and systematic stage for the development of long-term athletes called Long Term Athlete Development (LTAD). The stages are active start (age 0-6 years), fundamental (girls aged 6-8 years, boys aged 6-9 years), learn to train (girls aged 8-11 years, boys aged 9-12 years), train to train (girls aged 11-15 years, boys aged 12-16 years), train to compete (girls aged 15-21 years, boys aged 16-23 years) train to win (women over the age Gladi Jurnal Ilmu Keolahragaan, 12 (05), Desember- 383 Reggie Reginald, Fahmy Fachrezzy, Iwan Hermawan of 18 and men over the age of 19) and active for life (all ages) (Rizal, 2016). The development of sports technology is crucial to be used especially in Indonesia to increase the achievements of athletes both local and national. Development and advancement of sports technology is necessary for the advancement of sports achievement (Syakur et al., 2017). Technology has also become a close part of sports, from the moment of the game to the moment of training and athletes’ preparation. In the match, the use of technologies such as timekeeping systems used by sports is measured up to scoring systems using a sensor on the body protector in taekwondo sports. During the preparation period, technology is also used to help an athlete to achieve better performance and use digital test equipment that is more accurate in recording data. Based on the background description that has been described above, the researchers are very interested in researching the effect of balance, concentration, and eye-foot coordination on dollyo chagi kick skills in POPB athletes in DKI Jakarta using tools such as fusion sport and kinovea application also concentration grid. METHOD In general, the aim of this study was to determine the effect between the three independent variables or exogenous, namely: balance, concentration, and eye-foot coordination with dependent variable or endogenous, namely: dollyo chagi kick skills as well as analyzing the correlation of independent variables (balance, concentration, and eye-foot coordination) on dependent variable (dollyo chagi kick skills) either directly or indirectly. The research method used in this study was an associative quantitative approach using test and measurement techniques, while the analysis technique used was a path analysis. Path analysis is a technique to analyze a causal correlation that occur in multiple regressions if the independent variable affects the dependent variable, not only directly but also indirectly (Hakam, Sudarno, & Hoyyi, 2015). According to (Sugiono, 2019) population is a generalized area consisting of objects or subjects which have certain qualities and characteristics that are applied by researchers to be studied and then drawn conclusions. Based on the explanation above, the population in this study will Gladi Jurnal Ilmu Keolahragaan, 12 (05), Desember- 384 Reggie Reginald, Fahmy Fachrezzy, Iwan Hermawan be all athletes of POPB DKI Jakarta in 2021 numbered 20 people Sampling technique used in this study was total sampling. The reason for taking total sampling was because the population was less than 100. So the number of samples in this study was as many as 20 people consisting of 10 women and 10 men. Data collection technique used was research instrument tests. The dollyo chagi kick using dollyo chagi kick skills test. The balance using modified bass test. The concentration using concentration grid test and the eye- foot coordination using smart speed pro coordination test. The form of data analysis in this study were the form of numbers including: balance, concentration, coordination of eye-foot- hand and dollyo chagi kick skills. In accordance with the formulation of research methodologies and theoretical models that have been described, the analysis techniques used in testing this research hypothesis was path analysis.

The direct effect of balance on dollyo chagi kick skills Balance is one of the important factors in supporting daily activities or sport. Based on the results of the data analysis of research showed that the balance had a direct effect on dollyo chagi kick skills. The results of the data analysis showed that the significance value of the direct effect of balance on dollyo chagi kick skills was 0,032 < 0,05, so the balanced had an effect on Gladi Jurnal Ilmu Keolahragaan, 12 (05), Desember- 388 Reggie Reginald, Fahmy Fachrezzy, Iwan Hermawan dollyo chagi kick skills with the beta coefficient value of 0,243. An athlete who has good balance will generate good kick skills too. When doing kicks, the position of the body rests on only one leg, hence a good balance is needed for athletes to be able to perform good kicking techniques as a result of previous research which stated that balance is necessary because it has a significant correlation to the technical skills of an athlete both in the sport of the game (Zulman, Umar, & Atradinal, 2018) and in martial arts sports (Iskandar & Rismayadi, 2019) 2. The direct effect of concentration on dollyo chagi kick skills Concentration is the ability of someone to focus on one particular act so that other stimulus from both the outside and inside will not interfere. The results of the data analysis showed that the value of concentration signification directly influenced dollyo chagi kick skills 0,004 < 0,05, so the concentration influenced on dollyo chagi kick skills with the beta coefficient value was 0,567. An athlete who has good concentration will generate good kick skill as well. Concentration in athletes is needed when in a match because if athletes lose their concentration then it will be fatal, either getting defeat or injury. Concentration become a factor that must be considered and improved because it has a positive correlation with skills in sports (Taufik, 2019), including when doing kicks, concentration also has a role in kick speed (Ihsan, 2018) 3. The direct effect of eye-foot coordination on dollyo chagi kick skills Coordination is the ability of someone to perform an activity involving a series of aligned movements of several body parts. Eye-foot coordination is coordination where the eye is a mean of receiving stimuli from the outside and the feet is other limbs that perform movements according to the needed pattern and rhythm. The results of the data analysis showed that the value of eye-foot coordination signification directly influenced dollyo chagi kick skills 0,013 < 0,05, so the eye-foot coordination influenced on dollyo chagi kick skills with the beta coefficient value was 0,378. An athlete who has good eye-foot coordination will generate good kick skills as well. Sports activity frequently needs complex movements so that is required coordination of several body parts. By Gladi Jurnal Ilmu Keolahragaan, 12 (05), Desember- 389 Reggie Reginald, Fahmy Fachrezzy, Iwan Hermawan having good coordination, it will help a person in doing sports activities also technical skills, this is in line with previous research which stated that the skills of students will increase if the level of their coordination increases as well (Nurhidayah & Sukoco, 2015). When doing kick techniques, it is necessary to coordinate between the eyes to see the position of the body to see the target or opponent and the legs as the execution of the movements, so that eye- foot coordination has a direct effect on kick skills. 4. The direct effect of balance on eye-foot coordination Balance is one of the important factors in daily activities including when doing movements that require coordination. The results of the data analysis showed that the value of balance signification directly influenced eye-foot coordination 0,001 < 0,05, so the balance directly influenced on the eye-foot coordination with the beta coefficient value was 0,706. An athlete who has good coordination will generate good eye-foot coordination as well. In line with the theory of Radwan in Internation Journal of Science Culture which stated that “The special coordination abilities for athlete include each of the motor adaptation and adjustment ability, the ability to differentiate, reaction speed ability, orientation ability, balance ability, 6 coupling ability, the ability to sense the rhythm” so the balance is one of the ability of coordination (Radwan, 2014). 5. The direct effect of concentration on eye-foot coordination Concentration is the ability of someone to focus on one particular act so that other stimulus from both the outside and inside will not interfere. The results of the data analysis showed that the value of concentration signification directly influenced eye-foot coordination 0,035 < 0,05, so the concentration influenced on eye-foot coordination with the beta coefficient value was 0,297. An athlete who has good concentration will generate good eye-foot coordination as well. This is in line with previous research was conducted on volleyball athletes which stated that there was a direct effect of concentration on coordination of 35,16% (Asdi, Rifki, 2020) 6. The effect of balance on dollyo chagi kick skills through eye-foot coordination Balance is one of the important factors in daily activities including when Gladi Jurnal Ilmu Keolahragaan, 12 (05), Desember- 390 Reggie Reginald, Fahmy Fachrezzy, Iwan Hermawan doing kick movements because at the time of doing kick the body will only rest on one leg. The results of the data analysis showed that the balance had an effect on the eye-foot coordination of 49,8% and the eye-foot coordination had an effect on the dollyo chagi kick skills of 14,3%. And the indirect effect of the balance on the dolly kick was 26,7%. On kick movements is needed several body parts to generate a good technique. Coordination has a direct effect on balance and technical skills (Hidayat, 2018). 7. The effect of concentration on dollyo chagi kick skills through eye-foot coordination Concentration is the ability of someone to focus on one particular act so that other stimulus from both the outside and inside will not interfere. The results of the data analysis showed that the concentration had an effect on the eye-foot coordination of 8,82% and the eye-foot coordination had an effect on the dolluyo chagi kick skills of 14,3%. And the indirect effect of the concentration on the dollyo chagi kick skills was 11,3%. Concentration and coordination determine the outcome of a technique in sports, because if athlete have good concentration and coordination, they will be able to control the course of the game by influencing the results of the techniques used in the game (Hanief & Purnomo, 2019; Irawan, Permana, Akromawati, & Yang- tian, 2019). CONCLUSION 1. There was a significant effect of balance (X1) on dollyo chagi kick skills (Y). It can be concluded that the better the balance, the better the dollyo chagi kick skills will be generated. On the contrary, the lower the balance, the lower the dollyo chagi kick skills will be generated. 2. There was an effect of concentration (X2) on dollyo chagi kick skills (Y). It can be concluded that the better the concentration, the better the dollyo chagi kick skills will be generated. On the contrary, the lower the concentration, the lower the dollyo chagi kick skills will be generated. 3. There was an effect of eye-foot coordination (X3) on dollyo chagi kick skills (Y). It can be concluded that the better the eye-foot coordination, the better the dollyo chagi kick skills will be generated. On the contrary, the lower the eye- foot coordination, the lower the Gladi Jurnal Ilmu Keolahragaan, 12 (05), Desember- 391 Reggie Reginald, Fahmy Fachrezzy, Iwan Hermawan dollyo chagi kick skills will be generated. 4. There was an effect of balance (X1) on eye-foot coordination (X3). It can be concluded that the better the balance, the better the eye-foot coordination will be generated. On the contrary, the lower the balance, the lower the eye-foot coordination will be generated. 5. There was an effect of concentration (X2) on eye-foot coordination (X3). It can be concluded that the better the concentration, the better the eye-foot coordination will be generated. On the contrary, the lower the balance, the lower the eye-foot coordination will be generated. 6. There was an indirect effect of balance (X1) on dollyo chagi kick skills (Y) through eye-foot coordination (X3). It can be concluded that the better balance will generate good eye-foot coordination, so it will result good dollyo chagi kick skills as well. On the contrary, the lower the balance, the lower the eye-foot coordination, resulting in lower dollyo chagi kick skills 7. There was an indirect effect of concentration (X2) on dollyo chagi kick skills (Y) through eye-foot coordination (X3). It can be concluded that the better concentration will generate good eye-foot coordination, so it will result good dollyo chagi kick skills as well. On the contrary, the lower the concentration, the lower the eye- foot coordination, resulting in lower dollyo chagi kick skills. REFERENCES Asdi, F., & Rifki, M. S. (2020).
