FUTSAL DEFENSE STRATEGY MODEL FOR ATHLETS 15-17 YEARS OLD

The purpose of this study was to produce a futsal defense strategy training model for athletes 15-17 years old and to test the effectiveness of the futsal defense model for ages 15-17 years. The method used in this research is research and development. Data collection techniques using interviews, tests, and field observations. The results of the product effectiveness test by comparing the two groups; the treatment group using the product development, and the control group using the pretest and posttest designs. The average value of each group based on the test is the effectiveness of the experimental group is higher than the control group. The improvement of the futsal defense system for the age of 15-17 years at the time of the pre-test showed t-count = 13,405, >t-table = 1.69236, df = 34 and p-value = 0.000.00<0.005. Based on the comparison of the test results, the increase in test results for the experimental group increased significantly than the control group. The subjects in this study were athletes of Club futsal in Soppeng Regency aged 15-17 years and AFK Soppeng athletes aged 15-17 years. It is hoped that this research can provide benefits for sports practitioners, especially in futsal sport.


INTRODUCTION
Futsal is a type of indoor soccer This training model is developed systematically and logically so that this product is effective and feasible to use.
In making the product that the researcher develops, the researcher must consult with expert judgment or futsal experts in order to produce the perfect product.Based on the feasibility test conducted by the expert, it can be concluded that the variation of the futsal defense system model for players aged 15-17 years, the futsal defense system model is declared unfeasible so that the total futsal defense system model changes which initially amounted to 20 defense system models to 12 defense system models.and can be implemented to players aged 15-17 years.The variation of the defensive system model symbols 1,2,4,6,9,10,11,12,13,14 ,18,19, is a proper training model, so it is suitable to be applied to the futsal defense model item (symbol).For a large-scale test using a 10-item model for the next stage.The futsal defense system model for ages 15-17 years which has been evaluated by experts, then underwent a phase I revision with the results of the acquisition of 12 models that were feasible to be developed towards the next stage, namely small group trials.After the product design was revised, the next step would be to try out the model in a small group trial with 15 research subjects.The following is a summary of the results of small group trials:   d.The explanation given to the defense system is still not perfect.

CONCLUSION
Based on data that researchers obtained from field test results and research discussions it could conclude that: game that was invented by a physical education teacher from Montovideo, Uruguay, namely Juan Carlos Ceriani in 1930.In 1989 futsal held the first worldclass competition in the Netherlands and published the official list of futsal referees, literally means indoor football.The history of Indonesian futsal began in 2002 when Indonesia was asked by the AFC to organize the final round of the Asian level futsal championship in Jakarta.Iran won this tournament, while Indonesia was only able to win 1x and draw 1x from 4 matches so they did not qualify in the group stage.Futsal matches are held at the local, regional, national and international levels (Narlan, Juniar, & Millah, 2017).Not to mention in the South Sulawesi area, Soppeng Regency, the enthusiasm of the community in futsal is very high, especially among students who take part in various competitions such as the Regent Cup, Kalong Cup, IMPS Cup and provincial level competitions.Based on observations made by researchers in several futsal competitions that were participated in by these students starting at the district and provincial levels, there was a problem faced by futsal players, especially in maintaining their own defense, so that often goals were conceded both in defensive conditions and when counterattack by the opponent.Every futsal player must have the ability to survive, because in the futsal game the player's position shifts occur very quickly so that each player must be able to become a defender.In addition, Felipe Arruda Moura et al also stated that futsal "is an invasion game, to score a goal it is fundamental to advanced on the pitch" (Moura et al., 2011) After field observations, the researchers tried to dig up additional information by having discussions with several coaches and sports teachers who were in charge of the futsal team in their respective schools.The coach only concentrates on attacking strategies without realizing the importance of defensive training in futsal games.According to (Moore et al., 2014) futsal is a variant of football, is a sport played worldwide at an amateur, semi-professional and professional level.Based on (Permana, 2018) futsal has its own rules compared to football, all futsal regulations have been agreed upon by FIFA.However, by respecting the agreement of the relevant associations and who have prepared the Gladi Jurnal Ilmu Keolahragaan, 14 (03), September-332 Silmi Akhsin, Iman Sulaiman, Nofi Marlina Siregar principles of these rules, the rules of the futsal game can be changed to suit the orders of beginners, especially those under the age of 16, women or players who are old enough (over 35 years).Defense strategy is very important in futsal matches, especially in maintaining the team's winning score.A varied model of defensive training is also mandatory for a coach so that during training they can take advantage of the potential of the athlete, but the coach does not provide varied training so that it is not very effective, unattractive and leads to team defeat.Especially in the variety of defensive training provided.Each team must have a high quality of human resources to achieve achievements, therefore the coach must be able to develop the correct defensive strategy.Strategy and tactics are two things that complement each other and are closely related.(Benny Badaru, 2016).According to (Travassos et al., 2016) there are four elements in tactics and strategy in futsal games that must be considered, namely: (1) attacking, (2) defending, (3) transitioning from attack to defense, (4) transition from defense to defense.attack.The strategy must be in line with the tactics used in achieving a team's winning goal.And vice versa, because strategies without tactics are not in line, the expected goals will be difficult to achieve and even fail.Human resources such as coaches, management, owners, officials, and team players.There are 2 factors that affect the ability of futsal athletes, namely the first internal factors: physical, tactical, technical and mental abilities.The second external factors: trainers, coaches, nutrition, facilities and infrastructure, organization, spectators and referees.These two factors are very important because they are interconnected with each other in improving performance.This course should not be considered a small problem because athlete motivation is part of the mental aspect which is one aspect of training and is very closely related to achievement.Coaches are required to understand how to motivate players, especially during training.Each athlete has a different personality, characteristics, physical, social behavior and intellectual capacity so that to avoid the problem of saturation, the coach must be creative in creating a happy atmosphere in training and competing and be able to provide variations in training in the form of training sessions according to the athlete's needs.The model is basically something that describes a pattern of thinking.A model usually describes a whole concept that is interrelated.The model can also be seen as an attempt to concretize a theory as well as an analogy and representation of the variables contained in the theory," (Erfandy Wahyu, Mochamad Asmawi, 2019).Added (Suryadi Yusuf, 2017) "the model is an imitation of the original with the aim of obtaining something ideal by taking into account physiological factors, facilities, and the athlete's social environment".In principle, sport is a process of change for the better, namely to improve the physical quality, the functional ability of the body's equipment, and the psychological quality of the child or athlete being trained.(Prastya, 2019).The exercise model that is applied must also be adapted to the physical and psychological conditions of athletes aged 15 -17.The exercises that are applied must be arranged systematically starting from the easiest to the most difficult.Coaches are required to have clear goals and be able to design a good training model according to the needs of athletes aged 15 -17 in the game of futsal.Related to the background of the problem to be studied, the discussion of futsal strategy or tactics theoretically will discuss the defensive ability of the futsal team (Defensive).According to Joseph A Luxbacher defense is a skill or expertise in defending or fending off an opponent's attack.The basic principle of the defensive game is to guard (Muchtar Hendra Hasibuan, 2016).Scheunemann in (Sudjana, 2014) states that the principle of defense is (a) Back off between the ball and the goal itself, researcher uses all the steps in this development which are tailored to the characteristics to be studied.In this research consists of several stages of implementation.The stages in research are the most important aspects of next step that must be done is to make an initial product design in the form of a futsal defense strategy training model design to simplify the training process and get good training results.

Main product revision Implement product revision with inputs from the results of field trials early stage.The results of the small group trial will be used again as a base for a second evaluation after evaluation of previous experts that aim to improve survival strategy practice models before proceeding to the trial or trial stage of a large group.6. Main field testing Conducted a primary field test using 30 subjects.After the revision of the training model from the results of the previous trial was completed, the next step was to do a large group test or a test conducted on the field of 30 futsal athletes.Athletes who conducted field trials were futsal athletes from the input and results of the main field trials.The conclusions obtained from the field trials will be used as guidelines for the improvement and refinement of new products for the futsal defense strategy training model.The results of the athlete's response after doing the exercise directly are used as input for the evaluation of model improvements.Evaluation at this stage is the final evaluation of this futsal defensive strategy training model.After making improvements based on feedback from field tests, the product of a defensive strategy futsal training model is considered appropriate to be used and distributed.Operational field testing Compiling an effectiveness test or main product test using 35 subjects.The main purpose of this trial is to find out the correctness and effectiveness of the design and implementation in achieving the expected goals.There are several steps that must be taken, among others: (1) determine the group of research subjects (2) carry out the pretest (3) try the developed model (4) carry out the post-test (5) find the average score of the pretest and posttest and compare between the two (6) find the difference between the two averages through statistical methods (test-independent test) with the aim of knowing how much influence the use of the futsal survival Gladi Jurnal Ilmu Keolahragaan, 14 (03), September-336 Silmi Akhsin, Iman Sulaiman, Nofi Marlina Siregar model aged 15-17 from the use of the formula model to process the data as a whole uses the SPSS 21 application.9. Final product revision Revise the final product by considering input from field trials.The final evaluation stage is carried out at the large group field test stage.The results of student responses to the futsal defensive strategy training model in the futsal game are the same as the questions in the previous evaluation stage which will later be used as a product revision of the results of the defensive strategy training model in the futsal game and can to get a more effective and varied model of the futsal defense system.The development of the model on the futsal survival system was carried out based on data from needs analysis obtained through distributing questionnaires to futsal players aged 15-17 years and interviews with futsal coaches in Soppeng Regency, South Sulawesi.Furthermore, the data obtained will be validated by 3 futsal experts obtained through a questionnaire.The data is the result of a small group trial with 15 subjects, a field trial of 30 subjects, and an effective test of 35 subjects.
quality of the ball should also be considered to support the training process.
