Abstract

Food handlers who do not adhere to proper health and hygiene standards can significantly contribute to the risk of cross-contamination during food preparation. In the case of se'i beef (a traditional Indonesian smoked beef dish), such lapses can lead to contamination with harmful pathogens, including Escherichia coli (E. coli). Not washing hands thoroughly after using the restroom, handling raw meat, or touching contaminated surfaces can transfer E. coli from handlers to the beef. Using unclean knives, cutting boards, or other tools can spread bacteria from one food item to another.. The aim of the research was to assess the hygiene conditions of food handlers and the content of Escherichia coli bacteria in se'i beef. The research method is a survey with a cross sectional design. The research results showed that 70% of food handlers did not wear head coverings, 50% did not wear masks correctly, 100% spoke when handling food, 80% did not use aprons, did not use tools/equipment/hand pads when handling 70% of food and 90% of cow samples contained Escherichia coli bacteria.

Abstract

This study investigated the effectiveness of integrating the 9E Learning Cycle Model with STEM approaches to enhance students' Science Process Skills (SPS) in static fluid concepts. The research employed a mixed-methods embedded experimental design with 32 senior high school students. Quantitative data were collected through pre- and post-tests, while qualitative data were gathered via observations and interviews. Results showed significant improvements across all SPS components, with N-gain values ranging from 0.63 to 0.64, indicating medium gains. Students demonstrated enhanced abilities in observing, classifying, measuring, inferring, predicting, and communicating scientific concepts. The integrated approach facilitated practical application of knowledge, as evidenced by students' work on flood-resistant garage prototypes and wave-powered electricity generators. Qualitative findings revealed increased student engagement and improved problem-solving skills. The study concludes that the integration of the 9E Learning Cycle Model with STEM approaches offers an effective framework for enhancing students' science process skills and their ability to apply these skills to real-world problems. These recommendations aim to provide a more comprehensive understanding of the approach's potential in science education across various domains and student populations

Abstract

Adolescent reproductive health includes physical, mental and social aspects. Apart from being related to physical conditions such as diseases or disorders of the reproductive organs, reproductive health also involves psychological and social well-being which has an impact on the quality of life of teenagers. Factors that influence adolescent reproductive health include individual knowledge and attitudes as internal factors, as well as the family environment, the role of teachers, peers, and access to information as external factors. This research aims to analyze the influence of biological literacy and attitudes of adolescents regarding reproductive health in the PIK-KRR (Adolescent Reproductive Health Information and Counseling Center) program on healthy reproductive behavior in adolescents. This research uses an analytical observational design with a case-control method. The sample was taken proportionally with a 1:1 ratio, consisting of 250 teenagers with non-risky reproductive behavior and 250 teenagers with risky reproductive behavior. Data analysis was carried out using the Chi-square test. The results showed that biological literacy (p=0.000) and attitudes (p=0.000) had a significant effect on healthy reproductive behavior in adolescents. These findings emphasize the importance of knowledge and attitudes obtained from the PIK-KRR program in shaping healthy reproductive behavior.

Abstract

This study aims to identify the learning obstacles experienced by preservice chemistry teachers in studying the biodiesel topic in the energy section. The research method employed is qualitative descriptive, with the instrument is interview guide sheet. Participants in this study were students of the program study of Chemistry Education. The result of the interviews with prospective chemistry teachers reveals that the primary learning obstacle related to the biodiesel topic are epistemological learning obstacle, with many students struggling to understand and apply concepts in depth. While students generally grasp the basic differences between renewable and non-renewable energy and the benefits of biodiesel, they lack detailed knowledge about biodiesel production processes and potential feedstocks. Additionally, there is a reliance on provided materials and insufficient initiative in seeking additional information. To address these challenges, it is essential to design more structured in learning experiences

Abstract

The results of PISA 2022 show that Indonesian students are still weak in science literacy, mathematics, and technology-based problem solving, which are the basis for developing computational thinking (CT) skills. CT includes four primary indicators: decomposition to break down significant problems into smaller parts, pattern recognition to find similarities in data, abstraction to filter out irrelevant information, and algorithms to design systematic steps in solving problems. There are many ways to train CT, so this study uses block programming and the Quarky robot. This approach was chosen because it is visual and interactive and makes it easier to apply CT concepts practically, making it suitable for building 21st-century skills. The study was conducted in two high schools in Banda Aceh, involving 20 students from school A and 26 students from school B. Students were divided into two study groups in each school. Learning activities were designed based on STEMC in the form of Student Worksheets (LKPD), which include interactive learning scenarios, block programming challenges, and exploration of the Quarky robot's functions to solve real problems. The activities were arranged in stages, from a basic introduction to applying CT concepts in solving complex problems. The results showed a significant increase in students' CT abilities, especially in the algorithm indicator. Although both schools progressed, school B recorded higher growth, with better pre-test and post-test results than school A. This shows that block programming-based learning and Quarky robots effectively improve CT skills, which is essential in 21st-century education

Abstract

Exclusive breastfeeding rates are often low due to suboptimal breast milk production, which impedes infants' nutritional needs. This issue is frequently attributed to poor maternal nutrition, unbalanced diets, and irregular food consumption. Breast milk production relies on hormonal changes, notably the dominance of prolactin over progesterone and estrogen during childbirth. To address this, a study was conducted to evaluate the impact of specific foods boiled papaya leaves, almond milk, green beans, moringa leaves, ajwa dates, soy milk, and fennel leaves—on breast milk production. Employing a quasi-experimental design with a one-group pretest-posttest approach, the study involved 56 postpartum mothers whose milk production was substandard. These participants were selected in March 2023 using purposive non-probability sampling. A paired t-test was performed for bivariate analysis. Results indicated a significant improvement in milk production, with a p-value of 0.000, demonstrating that the consumption of these foods positively affects lactation. Consequently, it is recommended that breastfeeding mothers incorporate these foods into their diet to enhance milk production and support exclusive breastfeeding. Regular consumption of these specific foods can help meet infants' nutritional needs more effectively.
