Analisis Kemampuan Koneksi Matematis Siswa dalam Menyelesaikan Soal Ditinjau dari Self Efficacy
Get PDFThis study aims to determine how students\u27 mathematical connection abilities in solving problems are viewed from self-efficacy. This study is a descriptive study with a qualitative approach conducted at SMA Plus Muhammadiyah Merauke. The research subjects consisted of 3 grade 10 students selected based on the results of a self-efficacy questionnaire. Data collection techniques in this study were a self-efficacy questionnaire to determine the subjects, a mathematical connection ability test, and interviews. Data analysis techniques included data reduction, data presentation, and drawing conclusions. The results showed that: Students with high self-efficacy categories and moderate self-efficacy categories fulfilled the three indicators of mathematical connection abilities, namely being able to connect concepts between mathematical topics, connecting mathematics in other fields of study, and being able to connect mathematics in everyday life. Students with high self-efficacy categories and moderate self-efficacy categories were able to plan effectively, believe in their abilities, and succeed in completing a task. Students with low self-efficacy were unable to meet the three indicators of mathematical connection skills: connecting concepts between mathematical topics, connecting mathematics with other fields of study, and connecting mathematics with everyday life. Students with low self-efficacy tended to hesitate when attempting to solve mathematical problems and were unable to overcome the challenges they faced. Based on the research results, it can be concluded that self-efficacy levels influence students\u27 mathematical connection skills.

Get PDFThe purpose of this study is to examine learning outcomes in basic soccer skills through differentiated instruction. This research uses a descriptive research design with a quantitative approach, and the research method used is quantitative with the implementation stages of finding the value of independent variables, either from one or more variables (independent) without making comparisons or connecting them to other variables. Observation sheets and test sheets are used as research instruments. The results of the study show that the differentiated learning model was implemented “well” based on cognitive, affective, and psychomotor tests. Psychomotor tests showed a significant improvement in students\u27 motor skills, especially in learning passing, controlling, and dribbling techniques. Conclusion, based on the results of research and discussion on the learning outcomes of basic soccer techniques through differentiated learning, it can be concluded that the differentiated learning model applied at North Mollo 1 Christian Middle School to teachers for the Content (Input), process and product (output) indicators are all available and implemented well.

Get PDFThis research aims to determine: the difference in the effect of direct feedback and delayed feedback on volleyball smash skills; the difference in the effect of high and low hand-eye coordination on volleyball smash skills; the interaction between the two feedback methods and high and low hand-eye coordination on volleyball smash skills. The type of this research was a field experiment with a 2x2 factorial design. The research population consisted of 45 eighth-grade students at SMPN 2 Karau Kuala (Karau Kuala 2 Junior High School), while the research sample consisted of 24 students divided into 4 groups consisted of 6 students for each group. The research instruments were a volleyball smash skills test and hand-eye coordination test. The data were analyzed by using a two-way analysis of variance (ANOVA) with a significance level of 0.05. The research findings reveal that: (1) there is a difference in the effect between the direct feedback method and delayed feedback on the volleyball smash skills of students, with an average pretest score of 15.0 for delayed feedback and 16.0 for direct feedback, then the posttest results obtain 21.35 on delayed feedback and an average score of 23.48 for direct feedback; (2) there is a difference in the effect of high hand-eye coordination and low hand-eye coordination, it is proven by the average value of the final posttest data analysis showing that the group with high hand-eye coordination with the delayed and direct feedback method have an average score of 22.5. Meanwhile, the posttest group with low hand-eye coordination, who received direct and delayed feedback, obtained an average score of 22.4. and (3) there is an interaction between the feedback method and the level of hand-eye coordination on volleyball smash skills, with the results of the hypothesis test, as the Fo value of 5.47 and the Ftable value of 6.10.

Pengaruh Penggunaan Aplikasi Olahraga Terhadap Self-Presentation Pada Generasi Z
Get PDFThe purpose of this study was to evaluate the impact of sports app use on how individuals present themselves in the context of Generation Z, who grew up in the digital era and have the potential to express their identity through online platforms. Using quantitative methods, this study involved 136 Generation Z participants aged 15-25 who actively used digital-based sports apps. Data were collected using the Self-Presentation Tactics Scale – Assertive (SPRS; Lee et al., 1999) and the sports app usage scale developed by Baubonytė and Deliautaitė (2021). Data were then analyzed using JASP with validity, reliability, descriptive analysis, classical assumptions, and simple linear regression tests. The study findings showed that sports app use had a significant positive effect on self-presentation (p < 0.001) with a contribution of 62.2%, indicating that the higher the intensity of sports app use, the greater the tendency for individuals to actively present themselves in digital spaces. This research suggests that sports app developers consider users\u27 social and self-identity aspects as part of their strategies to increase digital engagement and participation.

Studi Literatur: Eksplorasi Potensi Abu Pelepah Aren sebagai Agen Pencerah dan Anti-Hiperpigmentasi
Get PDFThis study aims to present a comprehensive literature review on the potential of palm frond ash (Arenga pinnata, M) as a skin lightening and anti-hyperpigmentation agent. The research method used was a literature review through the PubMed, ScienceDirect, Google Scholar, and Scopus electronic databases and websites. The results of the study showed that there were 10 articles. The results of literature studies from various studies have shown that palm frond ash contains phenolic and flavonoid compounds that have the potential to inhibit tyrosinase activity, a key enzyme in melanin biosynthesis. In addition, the antioxidant properties of palm frond ash can also contribute to skin brightening effects by protecting cells from oxidative damage that triggers pigmentation. The conclusion indicates that palm frond ash has promising prospects as a natural ingredient in skin-brightening cosmetic products, although further research, particularly clinical trials, is still needed to confirm its efficacy and safety in humans
