The purpose of this study is to develop affective assessment of students in physics the form of interests students have using MySQL. There are 3 stages of the method used in this study, namely (1) Development, (2) Implementation, and (3) Evaluation. The subjects involved in this study were 265 students from Batanghari High School with 265 students using purposive sampling techniques. The results of this study are that the validator gives good results regarding the assessment of e-interest in the category given which is very feasible and obtained valid statements of 25 statements with a reliability value of 0.870. Then students' interest in physics dominated both categories was 54.4%. Student responses when using the e-interest assessment received a good response seen from the attitude of students, who were happy, excited and had a high curiosity towards this E-Assessment. It can be concluded that the e-interest assessment needs to be developed on a large scale.

Background: “Exercise is an activity to improve technical and physical competence of athletes”, most sports require an excellent physical aspect to win. Aerobic endurance is an essential point in the preparation of a wheelchair tennis training program. Aim: This research is to validate the circuit training program and test the exercise program on the aerobic endurance of wheelchair tennis athletes. Method: This research is development research with qualitative and quantitative approaches. Participants are wheelchair tennis athletes with ten males and four females, height 156-167± cm, weight 50-70± kg, age 31-35. Participants in the program validation were seven nationally licensed physical fitness trainers. The first stage qualitatively examines documents in articles, ebooks, textbooks to design the program. The second stage quantitatively applies the Delphi technique to assess the prepared training program. The third stage analyzes the assessment results with the content validity ratio formula and, the fourth stage tests the exercise program for six weeks. The instrument used is a multistage fitness test. Results: It has been found that the assessment items from seven experts show the content validity ratio value is 1.00, so it can be categorized as having good content validity. It has been found the mean posttest (N=14, M=249.14, SD=16.033) and posttest (N=14, M=241.71, SD=17.166). It has been found that hypothesis testing using paired samples t-test analysis (p=0.000<0.05). Conclusion: the circuit training exercise program has good validity, then based on the effectiveness test, there is an increase in the aerobic endurance of wheelchair tennis athletes.

Background: Kata is a series of moves competed in karate that require agility in its movements. Purpose: This research aimed to determine the validity and reliability of karate agility test in kata category. Method: This was a developmental research. The data were collected using the Delphi technique, involving 7 experts and test-retest. The participants were 20 karate aged at least 20 years old who have practiced karate for 6 years and have won regional competitions. This was to determine the test of empirical validity and reliability. The content validity was calculated using the Aiken formula, the empirical validity was calculated using Pearson Product Moment, while the reliability was calculated using the Cronbach Alpha. Results: The results showed that the karate agility test in kata category had high validity and reliability. The Aiken results were as follows: Item (1) size has fit the karate in kata category with a value of V 0.85; Item (2) distance between cones has fit with a value of V 0.80; Item (3) equipment has fit with a value of V 0.80; Item (4) number of test repetitions has fit with a value of V 0.80; Item (5) test procedure has fit with a value of V 0.80; Item (6) safe instrument has fit with a value of V 0.85; Item (7) agility has fit with a value of V 0.85; Item (8) score taking has fit with a value of V 0.80. The results of Pearson product moment r-table were 0.444, r-count (test 1) was 0.927, r-count (test 2) was 0.903, significance was 0.000 < 0.05. Conclusion: It can be concluded that the agility test can be used to measure the karate agility in kata category.

Physical activity intervention programmes have been found to effectively improve cardiorespiratory fitness, strength, and balance. However, few studies thus far have examined the effects of a circuit training physical activity adaptive programmed to improve the cardiorespiratory fitness, leg muscle strength and balance of the static environment of children with intellectual disabilities. The purpose of this study was to examine the effects of the adaptive activity circuit training of six weeks performed three times per week on the cardiorespiratory fitness (VO2 max), leg muscle strength, and balance of intellectually disabled children. The research method was experimental with group pretest-posttest design. The subject of this study was 15 male students with mild intellectual disabilities aged from 15 to 17 years who followed sport extracurricular activities taken by random sampling. The cardiorespiratory fitness (VO2 max) measurement used the modified Queen's College Step Test; leg muscle strength was measured using a leg dynamometer; static balance was measured using a stork stand test. The data were analysed with a paired samples test using SPSS. The results showed significantly increased (p<0.05) cardiorespiratory fitness, leg muscle strength, and static balance at the end of the intervention period of the circuit training physical activity adaptive programme. It has been concluded that the circuit training physical activity adaptive programme of six weeks, at a frequency of three times per week was effective for improving cardiorespiratory fitness (VO2 max), leg muscle, strength and balance.

The lack of learning facilities and infrastructure often results in problems and nuisance in the process of physical education learning, but it cannot be denied that the availability of standard learning facilities and infrastructure can also be said to be less proper to conduct physical education learning, especially when the standard facilities and infrastructure are utilized in the learning process with elementary school students as the participants. This research is aimed at revealing the creativity levels of civil-servant physical education teachers in modifying the learning facilities and infrastructure used in public elementary schools in Sewon Subdistrict, Bantul Regency, Indonesian country. The research was a descriptive quantitative study. The subjects of the research were 23 physical education teachers in public elementary schools in Sewon Subdistrict. The method used in the study was survey with the employment of questionnaire as the technique of data collection. Questionnaire was tested to 21 civil-servant physical education teachers excluding the population. Validity was tested using Product Moment formula proposed by Karl Pearson, and reliability was tested using Cronbach Alpha. The reliability of the questionnaire was 0.746. The data were analyzed using descriptive percentage technique. The results of the research reveal that the creativity levels of civil-servant physical education teachers in modifying learning facilities and infrastructure in public elementary school in Sewon Subdistrict are: in the category of "very low" with 9.09% (2 teachers), in the category of "low" with 22.72% (5 teachers), in the category of "average" with 40.90% (9 teachers), in the category of "high" with 22.72% (5 teachers), and in the category of "very low" with 4.54% (1 teacher). Therefore, it can be concluded that the creativity of civilservant physical education teachers in public elementary schools in Sewon Subdistrict, Bantul Regency, Yogyakarta, is in "average" category.
