Abstract

Purpose of the study: The importance of arm muscle strength and leg muscle explosive power in contributing to volleyball smash ability prompted researchers to analyze their magnitude in relation to student or athlete achievement in volleyball learning, which is part of the physical education curriculum program. Methodology: This type of research is quantitative, using a correlational approach with a quasi-experimental method. The population in this study were volleyball athletes with a sample of 20 athletes. The instruments used in this research were the hanging elbow test, vertical jump test and smash ability test. Meanwhile, this research data analysis technique uses statistical data analysis through linearity and correlation tests. Main Findings: Based on the research results, it was found that arm muscle strength and leg muscle explosive power make a significant contribution and have a big influence on the smash ability of athletes or students. Therefore, these findings require follow-up regarding the development of innovative teaching resources, such as textbooks or monographs, as a step to improve an athlete's or student's smashing ability in the volleyball learning process, thereby increasing students' motivation and learning outcomes. Novelty/Originality of this study: This research provides an in-depth analysis of the athlete's arm muscle strength and leg muscle explosive power on their smash ability by designing a training program and strategy that are more effective and suitable for improving volleyball smash ability.

Abstract

Purpose of the study: This study analyzes the comparative mathematics curricula between Indonesia and Australia to uncover various aspects of the education systems. The focus is on the similarities and differences between the curricula, systematically examining them in terms of objectives, materials, methods, and assessment, particularly in mathematics. Methodology: This study used a library method with the main data sources coming from 58 articles, 44 books, and 10 official documents in a qualitative descriptive manner. The research data analysis used the Systematic Literature Review method through the following steps: identification, screening, eligibility, and inclusion based on keywords, titles, abstracts, inclusion and exclusion criteria, and referenced literature. Main Findings: The mathematics curriculum in Indonesia and Australia at the Junior High School level is almost the same with a few differences, namely the focus on the profile of Pancasila students and providing more specific mathematical knowledge and skills to support the development numeracy and direct further fields of study in mathematics and other disciplines, so that it can add other aspects or components that researchers have never studied regarding the comparison of the mathematics curriculum in Indonesia and Australia. Novelty/Originality of this study: This analytical study of the comparative study of the Indonesian and Australian mathematics curriculum was conducted by citing various sources, namely articles, journals, official curriculum websites, books, and proceedings articles, thus providing a broader study of further studies on the development of the mathematics curriculum in Indonesia and Australia globally.
