Contribution of Arm Muscle Strength and Reaction to Straight Punches in Boxing Sports
Get PDFThis study aims to determine the contribution of arm muscle strength and reactionto straight punches in boxing at Sasana A 23 BC Bandar Lampung, both individually and collectively. This research is correlational research. The population of this study was 20 boxing athletes at the 23 BC Bandar Lampung gym. In this research, the sample collection method was total sampling. Datawere collected using tests and measurements with instruments in the form of a push and pull dynamometer for the arm muscle strength variable, whole body reaction for the reaction variable, and the straight punch test for the straight punch variable. The data analysis technique uses product- moment correlation analysis through prerequisite tests for normality and linearity. The research results showed that there was (1) a contribution between arm muscle strength andstraight punches, with a value of rx1.y = 0.607 > r(0.05)(28) = 0.374, and the contribution amount was 26.9%; (2) there is a contribution between the reaction to a straight punch, with a value of rx2.y = 0.447 > r(0.05)(28) = 0.374, and the magnitude of the contribution is 20%; and (3) there is a contribution between arm muscle strength and the reaction to a straight punch, with a calculated F value > F table (21.244 > 3.354), and the contribution amount is 61.1%

THE EFFECT OF STRIP STORY MEDIA ON STUDENTS' LEARNING OUTCOMES
Get PDFEffective communication between teachers and students plays a crucial role in the success of the learning process. Poor communication can hinder the delivery of material, making the learning process less engaging. One method to enhance learning engagement is through the use of strip story media. This medium is practical, simple, and enjoyable, supporting both teachers and students in creating a dynamic learning environment. This study aims to investigate the effect of using strip story media on students' learning outcomes in social studies. The research employed a one-group pretest-posttest experimental design. The results showed that the average score of students using strip story media was 80, higher than the control group's average score of 95. Statistical analysis using the Independent Sample t-Test indicated a significant effect, with the calculated t-value (t_calculated = 9.149) exceeding the critical t-value (t_table = 2.564) and a significance level (Sig = 0.000) below 0.05. This led to the rejection of the null hypothesis (H0) and the acceptance of the alternative hypothesis (Ha), confirming that strip story media significantly impacts the social studies learning outcomes of fourth-grade students at SD Negeri 080 Panyabungan. In conclusion, strip story media positively and significantly affects students' learning outcomes. The findings imply the need for integrating innovative teaching media like strip stories to enhance learning. Future research could explore its application in other subjects or educational levels to expand its benefits
JUNIOR HIGH SCHOOL STUDENTS' PERCEPTIONS OF DIGITAL TASK-BASED LEARNING FOR ENHANCING DESCRIPTIVE WRITING SKILLS
Get PDFThis study explores students' perceptions of task-based digital learning using Padlet to enhance descriptive writing skills. Conducted in a Catholic private school in West Java, the qualitative research involved six seventh-grade English as a second language learners (three high-scoring and three low-scoring) selected from a class of 22 students. Data were collected through face-to-face interviews after students completed descriptive writing tasks on Padlet. Findings revealed positive perceptions of Padlet’s multimedia tools, with students acknowledging that features such as images, videos, and GIFs improved their ability to write descriptively and organize ideas. Students also highlighted enhanced interaction and collaboration during tasks. Despite the benefits, some challenges in using Padlet were noted. The study contributes to educational technology and language learning by showcasing Padlet’s potential to foster creativity, collaboration, and multimedia integration in writing tasks. It provides valuable insights for K-12 and higher education curriculum design, teacher training programs, and the development of user-friendly digital learning tools
THE EFFECT OF USING QUIZIZZ APPLICATION AS AN ENGLISH LEARNING EXERCISE IN VOCABULARY MASTERY
Get PDFThis study aims to examine the impact of the Quizizz application on vocabulary mastery as part of English learning exercises among tenth-grade students at SMK Negeri 2 Panyabungan, focusing on recount text topics. It addresses challenges such as limited vocabulary mastery, low motivation and interest in learning English, and insufficient opportunities for practice. A quantitative approach with a quasi-experimental design was employed, involving experimental and control classes. Data collection included pre-tests, treatments, and post-tests using 20 multiple-choice questions on recount texts. The findings revealed that the experimental class, which used Quizizz, had a higher average post-test score (82) compared to the control class (67.5). Data analysis using the t-test showed a t-count of 4.965 and a sig. tailed (p) score of 0.001, with α = 0.05 and degrees of freedom (df) = 19. Since p < α (0.001 < 0.05), the alternative hypothesis was accepted, and the null hypothesis was rejected. These results indicate that using the Quizizz application significantly enhances students’ vocabulary mastery compared to traditional teaching methods. The study highlights the effectiveness of Quizizz in addressing vocabulary and engagement issues in English learning
CODE SWITCHING & CODE MIXING IN RITSUKI’S VLOG ON DIGITAL MEDIA TIKTOKː A STUDY OF SOCIOLINGUISTICS
Get PDFIn the digital era, multilingualism is increasingly visible on social media platforms like TikTok. This study examines Code Switching and Code Mixing in multilingual communication by analyzing content from the TikTok account Mega Kenichiro Official (Ritsuki’s Vlog) through a sociolinguistic perspective. The objective is to understand how speakers use Indonesian, Japanese, and Javanese in daily interactions and its impact on digital communication. Using a qualitative approach, the study analyzed 20 selected vlogs through note-taking, focusing on intra-sentential and intra-lexical code mixing, as well as inter-sentential code switching. The conversations were classified based on speakers and language patterns. The findings show that Japanese words are frequently mixed into Indonesian sentences, while code switching between Indonesian and Javanese occurs mostly in complete sentences. Additionally, the influence of these linguistic patterns extends to audience interactions, as reflected in their comments. This study concludes that multilingualism plays a significant role in shaping online discourse, making digital media a dynamic space for language interaction. Future research should explore the educational implications of code switching and code mixing in language learning
