Abstract

Social studies education in elementary schools is still teacher-centered; it appears that no models or media are employed in social studies education, and learning results have not yet reached the Minimum Competency Criteria (KKM). This study aims to examine the validity, design, and efficacy of the stay-two-stray and jigsaw learning models utilizing learning video media. This is a development study (Four-D Models) comprised of defining, designing, developing, and disseminating stages. Data collection methods are questionnaires, exams and interviews. This study was conducted in grade V SD Negeri Pakuncen and grade I SD Negeri Wonosari in the Pegandon District of the Kendal Regency. The findings demonstrated that establishing two stay-two-stray and jigsaw learning models with video learning to enhance social studies learning outcomes was highly valid, with a syntactic validation score of 92%, content of 87%, and RPP of 95%. The effectiveness of the offering indicates that learning outcomes have improved. Based on the pre- and post-test results, the N-gain test was classified as moderate with a score of 0.60. In addition, the student's emotional and psychomotor learning outcomes improved with excellent criteria. The benefits of research results make it simpler for students to comprehend the material presented by the teacher, improving student learning outcomes. This research concludes that establishing the stay-two-stray and jigsaw learning models with learning videos can increase learning outcomes and that students can collaborate, be responsible for helping one another solve problems, and motivate one another to excel.

Abstract

This study aimed to discuss the effect of yogurt fortified with pomegranate-fortified yoghurt, containing key antioxidant compounds such as anthocyanins, on male Wistar rats (Rattus norvegicus) induced by 1,2-dimethylhydrazine (DMH), a carcinogenic compound for colon cancer. The first stage of this study was testing antioxidant activity in various methods of making yogurt. A colon cancer rat group was induced with DMH with a dose of 20 mg/kg/body weight for 5 weeks by subcutaneous injection once a week. Induction of 1.2 DMH in experimental animals was carried out for 5 weeks, while the induction of pomegranate yogurt was carried out using oral induction every day for 4 weeks. The highest antioxidant activity was obtained from yogurt made by mixing plain yogurt and fermented pomegranate juice, where the proportion of pomegranate juice was greater, resulting in a percentage inhibition value of 77.96%. Giving pomegranate yogurt for 4 weeks was able to improve the histopathological picture of rats induced by 1.2 DMH. The best improvement in the histopathological in the colon of rats induced by 1.2 DMH was achieved by the P3 treatment group, where the proportion of pomegranate was greater when compared to plain yogurt.
