Evaluating the Validity and Effectiveness of Multiantro Tools in Diverse Applications
No full textAnthropometry is a science created from a new scientific sub-discipline called physical anthropology which is an implication of the development of anthropological studies. Anthropometry plays a very important role in the world of sports. An ideal anthropometric composition and supported by good technique will produce an athlete's excellent performance in the competition. Anthropometric characteristics, body composition and mass contribute to training and competition performance. Therefore, researchers have developed a multifunctional anthropometric measurement tool, several test items can be carried out simultaneously with the use of this tool, this tool is called 'Multiantro". The tests that can be done simultaneously with this tool are height, weight, sitting height and arm length tests. However, this tool still requires further review, so this study is intended to conduct a concurrent validity test phase of the Multiantro tool so that the results of its measurement can be accounted for. The method used was a cross-sectional design in which data from two instruments, a new instrument and a standardized instrument, were then collected at the same time from the same sample. The new instrument was tested to determine whether the results were consistent with the standardized measurement tool. The analysis results show that there is no significant difference between measurements using the Multiantro tool and measurements using conventional tools that have been standardized before. So it can be concluded that the Multiantro tool is also reliable in anthropometric measurements, just as when using previously existing tools. Even with this tool, tests can be carried out more practically because one tool is used to carry out four different types of test items
The relationship between anthropometry and biomotor ability on gymnastics potential at SD Negeri 1 Gentan
No full textThis study aims to analyze the relationship between anthropometric variables and biomotor abilities with gymnastics potential in elementary school students. The research method used a correlational quantitative approach involving 106 fourth and fifth grade students aged 9–11 years at SD Negeri 1 Gentan. Data were collected through anthropometric measurements (height, weight, arm span, sitting height) and biomotor ability tests (flexibility, core muscle strength, coordination). Data analysis was performed using Pearson's correlation test and multiple regression using SPSS. The results of the study showed that: (1) Height was significantly correlated with arm span (r = 0.687; p < 0.01) and sitting height (r = 0.434; p < 0.01), but not with biomotor ability; (2) Sit height has a positive relationship with core muscle strength (plank) (r = 0.346; p < 0.01), while arm span has a negative correlation (r = -0.209; p < 0.05); (3) Biomechanical abilities such as flexibility (split) and body rotation (air turn) are significantly correlated (r = 0.775 and r = 0.676; p < 0.01), but are not directly influenced by anthropometric variables. The conclusions of this study indicate that gymnastics potential is more influenced by technical training and flexibility than by body structure, although certain anthropometric variables such as sitting height and arm span play a role in core muscle stability. The implications of this study highlight the importance of combining anthropometric monitoring with structured biomotor training programs for the development of gymnastics potential in elementary school students.

Lesson study utilization in improving the teaching competence of physical education teachers at the elementary school level
No full textThis study aims to analyze the utilization of lesson study in improving the teaching competence of Physical Education (PE) teachers at the elementary school level. The lesson study process which consists of three main stages: planning, implementation, and collaborative reflection, was applied in the context of PE learning in several elementary schools. Participants in this study came from physical education teachers from the Palembang (Indonesia) area, totalling 10 elementary school PE teachers. The quality of learning is measured by looking at two aspects: teaching skills observed from recorded processes on how teachers managed the classroom and from students' formative class evaluation questionnaire after the learning process. The initial measurement and training on managing the classroom were given to the participating teachers before the lesson study was conducted. Furthermore, the lesson study program was carried out for four cycles. The same measurement was taken before and after the lesson study was concluded. All data in this study were processed using IBM SPSS 27 with paired sample t-test analysis and effect sizes. The results of the study found that lesson study at the before and after stages was proven to significantly improve the quality of teacher teaching (p<0.05), but not at the teaching skills (p>0.05). The results showed that lesson study effectively helped PE teachers identify and correct weaknesses in their teaching, improve pedagogical skills and facilitate more interactive and quality learning. In addition, lesson study also encourages the development of a collaborative culture among teachers, which contributes to improving professionalism and learning quality. This study concludes that lesson study is an effective strategy to improve the teaching competence of PE teachers at the primary school level, and it is recommended to be applied more widely in teacher development programs

No full textThis study aims to investigate the antioxidant and antibacterial activity from alkaloid extract. Alkaloid compounds were isolated from the endophytic bacteria Pseudomonas hibiscicola Wk, which was obtained from Hibiscus leaves. The alkaloid compounds were characterized using thin layer chromatography. The isolated alkaloid compounds were tested for total phenol content, and antioxidant activity. The phytochemical analysis of the alkaloid compounds from the endophytic bacteria Pseudomonas hibiscicola Wk showed a positive result for alkaloids, confirmed by an Rf value of 0.8125 which is similar to the Rf value of alkaloids from the periwinkle plant, namely vindoline (Rf = 0.85). Alkaloid compounds from the endophytic bacteria Pseudomonas hibiscicola Wk had the highest total phenol content of 2.390 mg gallic acid/gram sample at a concentration of 10.000 mg/L. These results indicate that the alkaloid compounds obtained contain phenol groups. The IC50 value obtained from the isolated alkaloid compound was 99.70 mg/L, demonstrating strong antioxidant capacity, and has the ability to inhibit the growth of E.coli and S.aureus bacterial
The effect of salung leaf extract (Psychotria viridiflora) on blood glucose levels in mice
No full textThis research is crucial in the context of the rising global prevalence of diabetes, a metabolic disorder that significantly affects public health. This study aims to determine the effect of salung leaf extract (Psychotria viridiflora) on blood glucose levels in hyperglycemic mice (Mus musculus). The study used 25 mice (Mus musculus) weighing 20-40 grams, divided into 5 treatment groups (P). Each group consisted of 5 mice, including a negative control, positive control, and three experimental groups with the administration of P. viridiflora extract at various doses (0.0112; 0.0225; and 0.0337 g/kgBW). Blood glucose measurements were conducted four times, on days 0, 6, 12, and 18, which included an initial glucose measurement, post-alloxan induction, and subsequent measurements after treatment. Among the three tested doses, the highest dose (0.0337 g/kg BW) proved to be the most effective in reducing blood sugar levels in alloxan-induced M. musculus, with effectiveness comparable to the standard drug Glibenclamide. Thus, the extract of P. viridiflora leaves shows strong potential as an alternative herbal antidiabetic therapy for M. musculus

Perempuan Si Rukat Nakan: Konstruksi identitas gender pada budaya patriarki masyarakat Suku Karo
No full textPenelitian ini mengkaji tentang pembentukan identitas gender pada masyarakat karo yang dikenal memiliki budaya patriarki yang kental. Pendekatan yang digunakan adalah kualitatif dengan metode deskriptif-analitis. Temuan dalam penelitian ini adalah penggunaan istilah kiasan sirukat nakan, sebuah ungkapan tradisional dalam masyarakat Karo yang digunakan oleh laki-laki untuk merayu perempuan agar bersedia menjadi istri yang menerima segala kekurangannya. Secara simbolik, ungkapan ini mencerminkan nilai kesetiaan dan penerimaan tanpa syarat dalam relasi patriarkal. Namun, saat ini sirukat nakan semakin jarang digunakan, terutama di kalangan generasi muda. Hal ini dipengaruhi oleh arus globalisasi yang membawa nilai-nilai kesetaraan gender serta pergeseran budaya dan bahasa, maka bahasa Karo perlahan tergeser oleh bahasa Indonesia dan bahasa global. Temuan ini menunjukkan transformasi ekspresi budaya tradisional, sekaligus menekankan pentingnya pelestarian istilah lokal sebagai bagian dari identitas kultural dan warisan sosial masyarakat. Meski demikian, penggunaan istilah tersebut masih bisa ditemukan dalam percakapan masyarakat tertentu di wilayah Karo
