Plyometric training is a physical training method aimed at improving explosive strength and movement speed, which are crucial in martial arts such as silat. This mini-research aims to analyze the effect of plyometric training on enhancing the quality of kicks in silat, particularly in terms of power, speed, and accuracy. The method used is qualitative, involving a plyometric training program over several weeks applied to individuals learning silat, with performance measurements of kicks taken before and after the intervention. The results show that plyometric training significantly improves lower limb explosive power, coordination, and kicking effectiveness. These findings suggest that plyometrics is an effective training approach and can be integrated into physical development programs, particularly to enhance kicking ability.

Stunting remains a significant public health challenge in Indonesia, particularly among children aged 6-59 months. Stunting, defined as low height-for-age, results from chronic undernutrition during the most critical periods of growth and development. This study aims to analyze the sociodemographic and socio-cultural factors associated with stunting in Gorontalo, Indonesia, to inform targeted interventions. A cross-sectional study was conducted with 325 children aged 6-59 months, selected consecutively. Data were collected using a structured questionnaire covering seven sociodemographic and two sociocultural factors, alongside the Individual Dietary Diversity Score (IDDS) questionnaire. Bivariate analysis was performed using Chi-Square tests, while multivariate analysis employed Logistic Regression to identify significant predictors of stunting. The prevalence of stunting among the sample was 35.7%. Bivariate analysis identified Birth Length, Birth Weight, Family Income, Exclusive Breastfeeding, Complementary Foods, Food Diversity, and Parenting as factors associated with stunting. Multivariate analysis revealed that Birth Length (OR=0.377; 95% CI: 0.188-0.754), Birth Weight (OR=0.231; 95% CI: 0.095-0.561), Exclusive Breastfeeding (OR=0.307; 95% CI: 0.164-0.575), and Food Diversity (OR=0.064; 95% CI: 0.033-0.123) were significant protective factors against stunting. Conversely, Family Income and Education were identified as confounding factors. The findings underscore the critical importance of the first 1000 days of life in preventing stunting. Efforts should improve maternal nutrition to ensure optimal birth weight and length, promote exclusive breastfeeding, and enhance dietary diversity among young children. Addressing these factors can significantly reduce the prevalence of stunting and improve child health outcomes in Gorontalo.

The lack of availability of teaching materials on basic embroidery techniques means students learn embroidery by relying on examples from previous assignments and searching for assignments on YouTube. Even though this example does not contain detailed steps, students still experience difficulties in understanding embroidery techniques, the art of arranging thread, adjusting and placing the right colors for good, embroidered decoration. Therefore, there is a need for tutorial-based textbooks on learning basic embroidery techniques. The aim of the research is to produce a tutorial-based textbook on basic embroidery techniques courses in the fashion design education study program at Medan State University. The development model uses the ADDIE model. The data collection technique uses a questionnaire and is analyzed using qualitative descriptive analysis. Validation of teaching materials is carried out by material experts and media experts. The validity test of material experts obtained 83.9% and media experts obtained 81.73% in the good category. The results of small group trials obtained 81.8%, medium scale trials obtained 82.87% and large group trials obtained 85.3%. The results of the research show that tutorial-based teaching materials are suitable for use in learning basic embroidery techniques courses. It is hoped that this tutorial-based teaching material can help teachers convey practical material in detail and make it easier for students to understand basic embroidery techniques independently.
