The aim of this research and development was to produce a product in the form of a waste utilization model book for elementary school students so that it can provide guidance for physical education teachers in providing fun, creative and meaningful learning. This study used the Borg and Gall Research and Development (RnD) method which consisted of ten steps, the subjects in this study were students of Tanjungsari Elementary School and Blanakan Elementary School with 68 subjects. The design of the experimental study was based on one group pretest posttest design. The stages of this study were: preliminary research, experts’ judgment, large group test, small group test and effectiveness test. The effectiveness test in this research was using Harvard Step Test. The results of the model effectiveness test showed that there was an increase in the use of waste for physical fitness, the pretest result was 33.57 and posttest was 36.63. From the data above, it can be concluded that there was an improvement after treatment. The results of the effectiveness test showed that the results of t-score = 7.818, df = 62 and p-value = 0.00 <0.05, which means that there were significant differences in the physical fitness of primary school students before and after the treatment. It can be concluded that the waste utilization model for physical fitness of elementary school students is effective and able to improve physical fitness.

This research aims to improve the anaerobic capacity and self-esteem of Canton Basketball Club athletes using 3x3 game. This study employs Kemmis and Taggart research model and was conducted in Palembang, Indonesia on March 2018. In this study, fifteen male athletes have volunteered for sixteen training meetings divided into two cycles and have performed 3x3 game with some modifications in each meeting. The Running-based Anaerobic Sprint Test (RAST) and interview are applied to examine the improvement of anaerobic capacity and self-esteem of athletes who perform 3x3 games before and after each cycle. A significant difference of fatigue index is observed. In pretest, the average is 5,35 W/s with a minimum value of 3,83 W/s and maximum value of 6,77 W/s, while in post cycle II is 3,60 W/s with minimum and maximum value of 2,07 W/s and 5,39 W/s respectively.  The result of this study reveals that the improvement of anaerobic capacity is various depend on the used modifications. Furthermore, 3x3 game is advantageous to improve anaerobic capacity. Hence, it is suggested that the upcoming studies explore the athletes’ mood and different type of small-sided games as well as its modifications for the improvement of athletes’ performance.

This study aims to determine the improvement of the results of badminton smash training through game modification in extracurricular students of Junior High School 4 South Sinjai. The subjects in this study were 25 students. The research method used is the action research with the design of kemmis and Mctaggart. This study consists of two cycles which each cycle consists of eight meetings. The test is done at the end of each meeting. The test is a badminton smash test. The results of the study of 20 students showed the results of a complete precycle test of 6 students. Students increased in cycle I as many as 14 students and continue to increase in cycle II as many as 18 students. Therefore, in the second cycle of success criteria has been achieved then the researchers do not need to take action on the next cycle. Thus it can be concluded that the exercise by using game modification can improve the result of badminton smash skills on the extracurricular students of Junior High School 4 South Sinjai-Sinjai regency.
