Abstract

Babies will have strong immunity if they get breast milk, because a number of nutrients are transferred from the mother. Breast milk helps protect babies from disease because of the anti-infective substances contained in breast milk and plays an important role in the growth and development of babies. Unfortunately, the target of 80% coverage of breastfeeding in Indonesia is still far from reality. This study aims to determine the effect of high-dose vitamin A supplementation on infant nutritional status. The research design was pre-experimental with a one-group pretest-posttest design conducted from June to September 2024. The statistical analysis used was the Wilcoxon Signed Ranks test with a significance level of 0.05. In this study, the population was all babies at the Remu Health Center, Sorong City. Then, screening of heterogeneous postpartum mothers who had received vitamin A capsules was carried out.

Abstract

This study was motivated by students' low understanding of IPAS (Natural and Social Sciences) material and difficulties during group discussions. Most students only enjoyed the practical activities and felt burdened by the notes that had to be memorised. Based on interviews with 50 students, it was found that confusion and the burden of memorisation were the main obstacles. To overcome this, the researcher developed the ‘LOSSING SADDLER’ (Local wisdom gaming for understanding and interesting learning combine with guessing word) method to improve the understanding of magnetic concepts and interest in learning IPAS in Phase C students. The research subjects included Grade V students of SD Kristen Lentera Ambarawa as the experimental class and students from six learning community primary schools in Semarang Regency as the comparison. Data were collected through unstructured interviews, documentation, tests and observations, and analysed descriptively quantitatively. This study aims to determine the effect of the ‘LOSSING SADDLER’ method on the understanding of magnetic material and the increase in student learning motivation. The expected results show that this method is able to increase students' understanding and interest in IPAS learning through a fun and meaningful approach.

Abstract

Strengthening science and environmental education through local wisdom is a strategic approach to creating contextual, relevant, and sustainable learning, particularly within indigenous communities. This study aims to explore how the Bunggu Indigenous Community in Pasangkayu, Indonesia, integrates local wisdom values into the management of science and environmental education. Utilizing a qualitative case study approach, data were collected through in-depth interviews, participatory observations, and document analysis involving traditional leaders, educators, and educational stakeholders. The findings reveal that scientific concepts such as ecology, environmental conservation, natural resource management, and traditional technology are taught through culturally inherited practices. The community's education management combines local wisdom with formal curricula, resulting in adaptive and contextual strategies for science and environmental learning. These findings emphasize that integrating local wisdom into science and environmental education not only enriches the learning process but also strengthens ecological awareness, cultural identity, and community participation in environmental preservation. This study contributes to the development of an education management model that is more responsive to local cultural contexts and highlights the need for educational policies that support local wisdom-based learning.

Abstract

Weak character education causes deviant behavior such as bullying behavior that often occurs in the school environment. Bullying behavior is one example of deviant and dangerous behavior characterized by the intention to hurt, power imbalance, mocking parents' names, making fun of physical conditions. Students do not fully understand the dangers of bullying behavior for mental health so that learning is needed using media in the form of comics. The objectives of this study are: to analyze bullying behavior experienced by students in the experimental group before and after implementing learning with comic media; to analyze the differences in bullying behavior experienced by students in the control group before and after implementing learning without comic media; to analyze the effectiveness of implementing learning using comic media between the experimental group and the control group without using comic media. The study used a quasi-experimental pretest-posttest control group design method. The population was 45 fifth grade students of SD Negeri Gugus 1 Kec. Siulak Mukai. The sampling technique was cluster random sampling totaling 30 students. The research instrument used a Likert scale. The data were analyzed using parametric statistics, namely Paired T-Test (T-Test) and Independent Sample T-Test. The results of the study showed: there was a significant difference before and after learning using comic media was given to the experimental group; There was no difference before and after learning without using comic media was given to the control group; there was a significant difference in the effectiveness of learning using comic media in the experimental group with the control group learning without using comic media. Therefore, learning using comic media is effective in reducing student bullying behavior.

Abstract

Elevated blood glucose levels are a hallmark of diabetes mellitus, which can lead to reproductive disorders, particularly affecting spermatogenic cells. This study aimed to evaluate the effectiveness of insulin leaf extract, noni fruit extract, and their combinations in reducing blood glucose levels and their impact on the number of spermatogenic cells in diabetic mice. A total of 36 male mice were divided into 12 treatment groups, including a normal control group, a negative control group (induced with alloxan 120 mg/KgBW), a positive control group (alloxan + metformin), and nine treatment groups with various doses of individual and combined extracts. Blood glucose levels were measured using Accu-Chek, and testicular histology was prepared following laboratory standards. Data were analyzed using the ANOVA test followed by the Duncan post hoc test. Results showed that the combination of insulin leaf extract at 150 mg/KgBW/day and noni fruit extract at 62.5 mg/KgBW/day was the most effective in reducing blood glucose levels. Additionally, the combination of 125 mg/KgBW insulin leaf extract and 50 mg/KgBW noni fruit extract significantly increased the number of spermatogenic cells. Thus, the combination of insulin leaf and noni fruit extracts shows potential as a natural antidiabetic therapy and for restoring spermatogenic cell function in diabetic conditions.

Abstract

Children with Developmental Language Disorder (DLD) show a high prevalence of psychological problems, yet understanding of individual variability in stress responses is limited. This study looked at how genetic and environmental factors affect stress responses in 200 preschool children (ages 3–6) from a PAUD in Bangkinang, Indonesia, including 100 with Developmental Language Disorder (DLD) and 100 without. Children with Developmental Language Disorder exhibited significantly greater cortisol reactivity (over 50% AUCi, p < .001), more pronounced decreases in heart rate variability (p < .001), and markedly higher anxiety spikes (p < .001) compared to control subjects. The multivariable regression analysis indicated a significant interaction between environmental and genetic variables (p < .001), collectively explaining 42% of the variation in cortisol reactivity. Cluster analysis revealed three distinct groups characterized by varying genetic and environmental risk factors: moderate responders (53%), severe stress (25%), and resilient individuals (22%). Our findings indicate that genetic and environmental factors interact in complex ways to alter the stress response of DLD, thereby supporting the development of intervention plans tailored to individual risk profiles.

Abstract

Iron overload (IO) is a condition characterized by an abnormal accumulation of iron in the body, which affects vital organs such as the liver, heart, pancreas, and endocrine tissues. Kwini mango (Mangifera odorata Griff) leaves, which contain mangiferin (a phenolic compound), have the ability to chelate Fe3+ by promoting the oxidation of Fe2+, potentially lowering blood iron levels. This study aimed to explore the potential of kwini mango leaf extract (KMLE) as an in vivo iron chelator for treating IO, using blood samples from an IO patient. The in vivo study assessed the effects of KMLE on ferritin, SGPT, SGOT, BUN, creatinine, and serum hematology levels in blood samples. Additionally, liver and kidney histopathology were examined as markers of iron chelation. The extract's standardization was performed to determine the mangiferin content in KMLE. The in vivo results showed a decrease in ferritin, SGPT, SGOT, BUN, creatinine, and hematological parameters. Comparisons between the KMLE group, deferoxamine group, and mangiferin group indicated a significant reduction in ferritin levels in both the deferoxamine and mangiferin groups when compared to the KMLE group at doses of 50 mg/200 g BW and 100 mg/200 g BW (Asym. Sig. (2-tailed) < 0.05). A similar pattern was observed for reductions in SGPT, SGOT, BUN, and creatinine levels at the same doses (Asym. Sig. (2-tailed) < 0.05). No significant difference was observed in the KMLE group at a dose of 200 mg/200 g BW (Asym. Sig. (2-tailed) > 0.05). KMLE demonstrates the potential to reduce serum ferritin, SGOT, SGPT, BUN, creatinine, and improve liver histopathology, suggesting its effectiveness as an iron chelator for treating IO.
