KEMAMPUAN REPRESENTASI DALAM MEMECAHKAN MASALAH MATEMATIKA BERDASARKAN GAYA BELAJAR

Yarmayani, Ayu
Abstract: Solving problems requires the ability to recall the information needed and represented both visually and verbally. This information is obtained, managed and recalled through a system called learning style. This research… was conducted at Asy-Syifa Al-Inayah Middle School, Jambi City, with the aim of obtaining a description of student representation in solving mathematical problems. Subjects in this study were selected using purposive sampling based on visual, auditory and kinesthetic learning styles. It is hoped that this research will provide benefits in improving mathematics learning. The results of the research show that the representation of auditory students and visual students in solving mathematical problems each fulfills three indicators, while kinesthetic students only fulfill two indicators of mathematical representation. In presenting information, visual and auditory subjects each tend to present it in the form of images (geometry or number patterns) and create situations based on the problem given. Meanwhile, kinesthetic subjects tend to only create images to clarify problems and facilitate their resolution. In solving problems, both visual and auditory subjects are able to solve problems by making patterns based on the problem given and making conclusions from a pattern. It's just that auditory subjects can shorten problem solving steps by using mathematical expressions. Meanwhile, kinesthetic subjects experience problems in solving combinatorics problems, where they are unable to present images or patterns that can help solve the problem.

Abstract: Public speaking is the activity of speaking in front of an audience with the aim of delivering information, providing explanations, entertaining, or influencing the listeners. It also involves conveying messages verbally… in front of an audience, whether in the form of speeches, presentations, lectures, or discussions. Public speaking is a crucial skill in various aspects of life, ranging from education to the professional world. This ability not only helps in academic presentations but also impacts how a person communicates and influences others. At the high school level and equivalent, students begin preparing for the next stage in their education or entering the workforce. Many challenges arise for students when speaking in front of an audience in a formal setting and explaining their presentations. Students face difficulties due to a lack of self-confidence, nervousness, panic, and a lack of mastery over the material they will present. In addition to a lack of self-confidence, other challenges include limited vocabulary, low communication skills, fear of judgment from others, and insufficient preparation. Basic public speaking training at Al Ma'shum High School in Kisaran would be highly beneficial for students to boost their self-confidence, enhance their communication skills, sharpen their critical and logical thinking abilities, and equip them for entering the workforce. The basic public speaking training will involve methods such as self-introduction exercises, role-playing, speech structure practice, impromptu speaking, expression training, intonation and articulation exercises, as well as feedback and evaluation.

Sahabuddin
Abstract: This study aims to examine the effect of volleyball learning on students’ gross motor development, which constitutes a crucial aspect in supporting adolescents’ physical fitness and movement skills. The research problem… lem arises from the low level of students’ gross motor abilities, as indicated by weak coordination, agility, balance, and muscle strength, resulting from limited structured physical activity and the dominance of conventional teaching approaches. A quantitative approach was employed using a quasi-experimental pretest–posttest control group design to evaluate the effectiveness of systematically designed volleyball instruction. The findings reveal a significant improvement in the experimental group, with the mean score increasing from 64.28 to 78.45, while the control group showed only a modest increase from 63.91 to 68.12. Statistical analysis indicates a significant difference with a t-value of 6.214 and a significance level of 0.000, supported by an effect size of 1.28, which falls into the large category. These results confirm that volleyball-based learning is effective in enhancing overall gross motor skills through structured and varied movement activities. The novelty of this study lies in its comprehensive approach that integrates multiple motor components within a unified analytical framework, as well as the use of effect size to strengthen the practical significance of the findings. This study provides a meaningful contribution to the development of more innovative, interactive, and movement-based physical education learning models to optimize students’ motor development sustainably.

Sahabuddin
Abstract: This study aims to evaluate the effectiveness of volleyball game–based tactical learning in improving the fundamental movement skills of students at SMP Negeri 2 Makassar. The research employed a quasi-experimental method… hod with a non-equivalent control group design, involving 40 seventh-grade students divided into an experimental group (n=20) and a control group (n=20). The experimental group received tactical game–based learning focused on understanding game situations, decision-making, and applying tactical concepts within the context of play. In contrast, the control group followed conventional technique-based instruction emphasizing repetition of basic movements. Measurement of fundamental movement skills, particularly manipulative skills in volleyball, was conducted using the Fundamental Movement Skills (FMS) test during the pretest and posttest stages. Data analysis was carried out descriptively and inferentially using paired-sample t-tests to identify changes within each group, as well as independent-sample t-tests to examine differences in improvement between groups at a significance level of 0.05. The results showed that both groups experienced significant improvement in fundamental movement skills. However, the improvement in the experimental group was statistically more pronounced than in the control group, accompanied by a large effect size indicating a strong impact of the treatment. These findings confirm that volleyball game–based tactical learning provides a more effective contribution to developing students’ fundamental movement skills compared to conventional instruction. Theoretically and practically, this study recommends the implementation of tactic-based approaches as more relevant, authentic, and competency-oriented learning strategies in physical education.

Lukmanul Hakim, Muh. Hasani, Muh. Rusli Umaini
Abstract: Individuals with Autism Spectrum Disorder (ASD) commonly face challenges in independent learning and mastery of functional skills due to deficits in communication, social interaction, as well as repetitive and restricted… behaviors. The Treatment and Education of Autistic and Related Communication Handicapped Children (TEACCH) approach was developed to address the specific educational needs of this population through structured, visually based, and strengths-based learning. Although the effectiveness of TEACCH has been widely reported globally, studies systematically examining its application within the Indonesian educational context remain limited. This study aims to critically evaluate the effectiveness of the TEACCH approach in enhancing independent learning among children with ASD in Indonesia. Using a systematic review method based on the PRISMA protocol, 15 scholarly articles published between 2017 and 2024 were thematically analyzed to identify TEACCH’s contribution to increasing independence in academic contexts and activities of daily living (ADL). The analysis revealed that TEACCH implementation consistently enhances children’s independence, as indicated by significant improvements in academic task completion (with an average score increase of 34–50 points), as well as improvements in ADL skills such as dressing, eating, and maintaining personal hygiene. The success of this approach is determined by the integration of structural elements, such as environmental organization, the use of visual aids, consistent routines, and collaboration between teachers and parents. This study concludes that TEACCH is an adaptive, effective, and relevant approach for implementation within the Indonesian education system. The novelty of this research lies in its contextual focus on TEACCH application in Indonesia, as well as strategic recommendations for its integration into special education (SLB) and inclusive school curricula through systemic educator capacity-building.

Sahabuddin
Abstract: The management of volleyball training sessions among collegiate athletes faces complex challenges due to the lack of integrated scientific approaches, which may reduce training effectiveness and increase the risk of fatigue… gue and injury. This study addresses the suboptimal implementation of periodization-based microcycle planning, training load monitoring, and recovery strategies within a unified system. The objective of this research is to examine the effectiveness of an integrated training management model in improving athletes’ performance and physiological condition. A quasi-experimental method with a pretest–posttest control group design was employed, involving 40 collegiate athletes over an eight-week period. The results indicate that the experimental group showed significant improvements in countermovement jump by 12.2% and spike reach by 3.1%, accompanied by a reduction in sRPE by 11.5% and an increase in recovery scores by 22.5%, while the control group demonstrated no meaningful changes. These findings suggest that the integration of microcycle planning, internal and external load monitoring, and structured recovery strategies enhances physiological efficiency, neuromuscular adaptation, and the sustainability of athletic performance. The study concludes that the integrated training management model is more effective than conventional approaches as it enables objective and systematic control of training intensity. The novelty of this research lies in the development of an integrated training session management model that combines three key components in an applicable, practical, and context-appropriate manner for collegiate athletes, thereby bridging the gap between sport science theory and coaching practice.

Peran Gizi Olahraga dalam Meningkatkan Power dan Daya Tahan Atlet Bola Voli: Sebuah Tinjauan Literatur

Sahabuddin
Abstract: Modern volleyball requires complex physical capacities, particularly explosive power and match-specific endurance that are closely associated with the performance of anaerobic and aerobic energy systems. Increasing performance… rmance demands indicate that training programs alone are insufficient to produce optimal athletic performance; therefore, sports nutrition strategies become a crucial component in supporting athletes’ physiological adaptation processes. The research problem addresses how sports nutrition contributes effectively to improving the power and endurance of volleyball athletes based on recent scientific evidence. This study aims to systematically analyze the contribution of sports nutrition to enhancing the physical capacity of volleyball athletes through a scientific literature review approach. The research method employs a Systematic Literature Review (SLR) using the PRISMA framework to examine articles indexed in Scopus and SINTA published between 2015 and 2024. The identification process yielded 312 articles, followed by a rigorous screening and eligibility assessment that resulted in 22 articles meeting the inclusion criteria, with 10 core studies analyzed in depth to obtain a synthesis of relevant scientific findings. The results indicate that carbohydrate periodization of 6-8 g/kg body weight per day contributes to an improvement in vertical jump performance by approximately 3-6%, while optimal protein intake of 1.6-2.2 g/kg body weight per day increases peak power by about 4-8%. Creatine monohydrate supplementation of 3-5 g per day has been shown to enhance explosive power by 5-12%, whereas beta-alanine supplementation improves anaerobic work capacity by 8-14%. Hydration strategies and carbohydrate regulation also contribute to an increase in VO₂max by 2-5% and reduce the fatigue index by 6-10%. The findings confirm that sports nutrition functions as an essential mediator between training stimuli and the neuromuscular as well as metabolic adaptation responses of athletes. The novelty of this study lies in its conceptual synthesis that positions nutritional periodization as an evidence-based integrative strategy for sustainably optimizing the power and endurance of volleyball athletes.
