THE EFFECT OF ARM MUSCLE EXPLOSION, HANDS EYE COORDINATION AND ACHIEVEMENT MOTIVATION ON SPIN PASS SKILLS AT DKI JAKARTA RUGBY ATHLETES

This research endeavor strives to elucidate the impact of Arm Muscle Explosive Power, Hand Eye Coordination, and Achievement Motivation on the proficiency of Spin Pass Skills in DKI Jakarta Rugby Athletes. The research sample encompasses a total of 45 DKI Jakarta rugby athletes, out of which 25 are male and 20 are female. This study utilized the multivariate associative research approach, which incorporated various survey methods and both test and non-test techniques. Analysis was conducted through a path analysis approach, with a statistical significance level of 0.05. the conclusion of each research finding shows (1) There is a direct influence between each independent variable Arm Muscle Explosive Power (X 1 ), Hand Eye Coordination (X 2 ), and Achievement Motivation (X 3 ), (2) There is a direct effect of each independent variable {Arm Muscle Explosive Power (X 1 ), Hand Eye Coordination (X 2 ), and Achievement Motivation (X 3 ) have a direct influence on Spin Pass Skills (Y), (3) There is an indirect effect of Arm Muscle Explosive Power (X 1 ) through Achievement Motivation (X 3 ) on Spin Pass Skills. (Y). There is an indirect effect of Eye-Hand Coordination (X 2 ) through Achievement Motivation (X 3 ) on Spin Pass Skills. (Y). Thus, Spin Pass Skills can be improved through increased Arm Muscle Explosive Power, Hand Eye Coordination and Achievement Motivation.


INTRODUCTION
Rugby is a sport that is played with full body contact. Rugby is a complex game and there are basic structured techniques, played with concentration and spread of different players (Greenwood, 2003). Rugby is a dynamic team sport (Lamb & Croft, 2016), requires a combination of fitness and physical ability (Higham, Pyne, Anson, & Eddy, 2012), implementation of technical skills (Meir, 2012), played with the ball as the main object (IRB, 2014). Rugby is a physically demanding, skillful sport, performed an intermittent high intensity (Chiwaridzo, Ferguson, & Smits-engelsman, 2020).
The sport of rugby usually involves open skills as the environment is constantly changing and movement has to be adapted (Arvinen-Barrow, Weigand, Thomas, Hemmings, & Walley, 2007). Rugby athletes also need to efficiently execute various technical and tactical skills during matches (Hendricks, Lambert, Masimla, & Durandt, 2015).
The sport of rugby needs special attention for the development of future generations of athletes who are expected to reach the highest level of play that can represent the region or country.
Club participation in a match that is included can help coaches and administrators to obtain results from what has been trained during training and be used as material for correction and evaluation so that athletes can improve their quality much better.
Judging from every match that the DKI Jakarta rugby club has participated in various national and international championships, there are many things that need to be used as corrections and improvements to improve the quality of the team and the quality of better athletes. One of the capitals to achieve the highest achievement in a sport is to have and master basic technical skills in playing well and correctly.
There are several aspects that need to be developed to achieve the highest achievement, namely aspects of basic technique, tactics, strategy and mentality of athletes. Improving these aspects requires a relatively long time and process so that athletes are able to perform skilled and perfect movements.
Success will come if the athlete's ability can read the situation and play what is in front of him, including the transition to play (Mckay & O'Connor, 2018). Each team tries to score by kicking, passing and bringing the ball past the opponent's defense and placing it on the ground (try line) to get a score (Sutanto, 2016). In rugby union, most points are accrued when scoring a try (Grant et al., 2003). Rugby requires good skills so that the pattern of the game can run and score.

Variable Spin pass Skill (Y)
The results from the data description

1) Direct Influence
To calculate the direct effect, the following formula is used:  3. There is a direct effect of arm muscle explosive power on spin pass skills. This means that the better the explosive power of the arm muscles, the better the spin pass skills that will be obtained.
Conversely, the lower the explosive power of the arm muscles, the lower the spin pass skills obtained.
4. There is a direct effect of eye-hand coordination on spin pass skills.
This means that the better eye-hand coordination, the better the spin pass skills that will be obtained. On the other hand, the lower the eye-hand coordination, the lower the spin pass skill obtained.
