Abstract

In the current era of disruption, the need to learn English is very important, therefore several digital applications have been created to make learning English easier, especially for students. U-Dictionary is a popular English learning application that can be used as an option, therefore this research aims to analyze the effectiveness of using the U-Dictionary application in increasing students' interest in learning at Madrasah Ibtidaiyah and what students' perceptions are regarding the use of U-Dictionary in increasing interest in learning languages. English at Madrasah Ibtidaiyah. This research uses mixed methods. The data collection technique used in this research is a questionnaire. Data analysis used the paired t-test data analysis technique with the Shapiro-Wilk normality test. Meanwhile, the qualitative analysis uses content analysis. Based on the results of data analysis, it can be seen that the U-Dictionary application is effective in increasing students' interest in learning at Madrasah Ibtidaiyah with a significance value (<0.001). The results of the questionnaire regarding students' perceptions of using U-Dictionary, the majority of respondents had a fairly high level of use, a fairly high level of self-confidence, the ability to understand good English vocabulary, a fairly high level of interest in learning English, and felt that learning English is quite effective or very effective.

Abstract

This study aims to evaluate the effect of High-Intensity Interval Training (HIIT) on improving physical endurance performance and reducing the risk of injury in football players. This study utilizes a quasi-experimental design with a one-group pre-test and post-test approach involving 20 football players aged 18 to 25. Resistance performance is measured through VO₂ Max, while injury risk is assessed using body functional tests that evaluate muscle imbalances and biomechanical weakness. After undergoing the HIIT program for 8 weeks, the results showed a significant improvement in the players' VO₂ Max from an average of 61.87 ± 6.03 ml/kg/min to 63.60 ± 6.03 ml/kg/min, with an increase of 2.8% (p < 0.05). In addition, the risk of injury also decreased from an average of 4.11 ± 0.86 to 4.07 ± 0.86, with a decrease of 1.1% which was also statistically significant (p < 0.05). The increase in VO₂ Max reflects the increase in the player's cardiovascular endurance, which is crucial for dealing with the physical demands of a football match. The research also reveals that the reduced risk of injury suggests that HIIT effectively improves muscle stability, flexibility, and balance, which are important in preventing muscle and joint injuries in football players. In conclusion, HIIT is an efficient and effective training method to improve physical performance and reduce the risk of injury, so it is recommended to be applied in the training program of football players
