INTRODUCTION
Physical education is a medium for encouraging the development of motor skills, physical abilities, knowledge, reasoning, appreciation of values (attitudes, mental, emotional, spiritual and social), as well as the habit of healthy lifestyles which lead to stimulating good growth and development. One of the main problems in physical education in Indonesia to date is the ineffectiveness of physical education teaching in schools. This condition is caused by several factors, one of which is the limited learning resources and infrastructure used to support the physical education teaching process (Azhar et al., 2020).
To minimize these limited conditions, it is necessary to have extracurricular activities which are mandatory activities organized by educational units as a forum for character development activities (Arisman et al., 2022) in order to expand potential, talents, interests, abilities, personality, cooperation and optimal student independence. According to Arikunto in (Nopriansah & Nugraha, 2023), extracurricular activities are additional activities outside the program structure which are generally optional activities. Extracurricular activities for students can take the form of activities in the arts, sports, personality development and other activities that have positive aims for the progress of the students themselves (Pratama et al., 2019).
Volleyball is a type of big ball game that is played in teams consisting of 6 people playing against each other. The game of volleyball requires movement coordination that can really be relied on to carry out all the movements in the game of volleyball. The techniques in playing volleyball consist of service, passing, block and smash (Nailufar & Hartono, 2022). The basic technique that needs to be mastered in playing volleyball is gradual and consistent physical training (HERWIN, 2019). Considering that practice does not develop students' talent or initiative to think, teachers should pay attention to the reasonableness of using the drill method to obtain dexterity or skills (Bompa & Buzzichelli, 2019) from what has been learned.
Today's modern volleyball game requires good physical endurance, to develop movement speed, agility and toughness (Putra, 2019). Especially the explosive power of the legs to reach the maximum height of the vertical jump, whether in smashing, serving or blocking. Smash in volleyball requires strong physical conditions, especially explosive leg strength to reach the maximum jumping height (Saputra & Aziz, 2020). In volleyball, leg muscle power is really needed, especially when smashing. According to Bafirman in (Octavianus et al., 2018) power is a very important biomotor component because power will determine how hard a person can hit, how hard a person can kick, how fast a person can run, and how far a person can push and so on. so on (Nugroho, 2015).
Smash is a strong blow where the hand makes full contact with the ball at the top, so that the ball travels steeply at high speed. If the blow is higher above the net, the ball can be hit sharply downwards Winarno Dalam (Pulungan, 2022). Cooperation between muscles, namely arm muscles, abdominal muscles, leg muscles, hip muscles, shoulder muscles, and the flexibility of the togok greatly influences the success of performing smashes, especially back attack smashes. Pranatahadi in (Hermansyah & Permadi, 2018) the smash back attack in volleyball is an attack from the back line, the back smash is done as a variation of attack to avoid strong blocks.
One training method that can be used to improve this ability is the box jump training method. Box jump training is one of the exercises to improve vertical jump by jumping vertically upwards with the help of box equipment (Pratiwi et al., 2020).
Based on the researcher's observations and information obtained from the physical education teacher who also doubles as the men's volleyball extracurricular coach at State High School 18 Bone, the problem currently facing is that many students do not know the volleyball smash technique well, this was obtained from training process at school in general, but it is difficult to carry out smash movements well and precisely on target because you don't have the right basic jump. So the learning method that can be used to improve extracurricular smash ability in men's volleyball is by using drill and box jump training methods. The aim of this research is to find out how the drill and box jump training methods influence leg power and smash back attacks in men's volleyball extracurricular activities at SMA Negeri 18 Bone.
METHOD
This research is quantitative research using The Static Group Pretest-Posttest Design research design (Sugiyono, n.d.). This research used two classes where class A was given Drill treatment and class B was given Box Jump treatment. The population in the study was 30 students with a research sample of 20 students. Sampling used
tests and hypothesis tests. The paired t-test analysis technique is carried out using the Paired Samples Test and the unpaired t-test uses the Independent Samples Test.

Based on the results of the research that has been carried out, the students' smash back attack ability is less than optimal because previous training activities did not use any training program at all. This is due to an inconsistent routine training schedule. Meanwhile, to master the smash back attack ability, you need to practice using drill and box jump methods. The drill training method is a repetitive activity to improve students' abilities in carrying out training activities, which aims to strengthen an association or perfect a skill so that it becomes permanent.
This exercise is very popular with students who have good skills in handling the ball during volleyball games, so there are no obstacles during the training process. In contrast to students who do not yet have skills in handling the ball during volleyball games, they had quite difficulty in the first few meetings, but after going through several learning processes the students were able to adapt to the training given.
Based on the results of the drill practice t test analysis, the mean pre test data was 15.20 seconds and the post test was 20.10 seconds. So it can be concluded that there is a significant effect of drill training on leg power in smash attack back extracurricular men's volleyball at SMAN 18 Bone.
The method used is box jump training to increase the vertical jump by jumping vertically upwards with the help of box equipment (Risma et al., 2020). Box jump training is an exercise in jumping onto a box and then jumping down by placing both feet at the same time. The effect resulting from box jump training is of course greater because when jumping the load is heavier. So the muscle fibers work harder and contract very strongly.
Based on the results of the box jump exercise t-test analysis, the mean pre-test data was 15.30 seconds and the post-test was 17.50 seconds. So it can be concluded that there is a significant influence of box jump training on the strength of the body in the smash attack back extracurricular for men's volleyball at SMAN 18 Bone. Based on the results of the independent T test analysis of drill and box jump training on leg power in the smash back attack of the men's volleyball extracurricular at SMAN 18 Bone, it shows that the mean post test for drill training was 20.10 seconds while the post test for box jump training was 17.50 seconds. With the difference in post test results for groups A and B of 2,600 seconds. The test results show that box jump training is more effective than drill training on leg power in the smash back attack. Men's volleyball extracurricular at SMAN 18 Bone.
Based on the analysis that has been carried out, it shows that there is a significant effect of drill training on leg power in smash attack back. Men's volleyball extracurricular at SMAN 18 Bone, shown by the calculated t value of 3.665> t table 2.145 and a significant value of 0.005 <0.05 with a time difference of 4. .90 seconds. Then, there was a significant effect of box jump training on leg power in the smash attack back extracurricular for men's volleyball at SMAN 18 Bone, shown by the calculated t value of 2.703> t table 2.145
