Abstract

Primary dysmenorrhea is a common complaint among adolescent girls, affecting daily activities. Herbal medicine has been widely used as an alternative treatment. This study aims to compare the effectiveness of herbal medicine and mefenamic acid in reducing primary dysmenorrhea pain among 460 high school students in South Sumatra. Pain levels were measured using the Numeric Rating Scale (NRS) at specific time intervals. Results indicate that herbal medicine has comparable effectiveness to mefenamic acid in reducing pain at the 60th minute. While the mefenamic acid group was given 500 mg of mefenamic acid. The degree of pain was measured using the Numeric Rating Scale (NRS) before treatment, at 14, 30, 45, and 60 minutes after treatment. Results: The significance value of the pain level of both groups at 60 minutes (0.244) > α 0.05 (error level 5%). This shows that there is no significant difference between the differences in the mean pain level given herbal medicine and mefenamic acid at 60 minutes. So it is concluded that herbal medicine is able to reduce the level of pain the same as mefenamic acid at 60 minutes. This also means that herbal medicine can be used as a therapy for primary dysmenorrhea as well as the use of mefenamic acid at 60 minutes. Herbal medicine can be used as a therapy for primary dysmenorrhea in adolescents. This study provides initial evidence that herbs and chemical drugs actually have the same efficacy if given in the appropriate amount.

Abstract

This study aims to test the effect of experimental learning models on the cognitive learning outcomes of 4th grade elementary school students on the material of energy transformation in the Independent Curriculum. Quantitative methods with quasi-experimental designs were used, involving all 4th grade elementary school students in Tugu District, Semarang City, divided into experimental and control classes. The experimental class was taught using an experimental learning model, while the control class used the lecture method. Cognitive learning outcomes were measured using tests that included indicators of essential competency achievement in the material of energy transformation. Data were analyzed using normality tests, homogeneity tests, t tests, N-Gain tests, and hypothesis tests to compare the average post-test scores between the two groups. The results showed a significant difference between students' cognitive learning outcomes in the two groups. The data obtained in the t stat column or tcount was 4.005, and the Critical two-tail or ttable was 1.972. The tcount > ttable = 4.005 > 1.972 was obtained based on this. So, it can be concluded that, with a significance level of 5%, Ha is accepted and H0 is rejected. This study concludes that the experimental learning model positively affects students' cognitive learning outcomes on energy transformation material in the Independent Curriculum and can be an effective alternative to improve cognitive learning outcomes

Abstract

This study explores the development of analog rice from composite flours of moringa, purple sweet potato, and cassava to diversify local food and enhance nutritional value. The purpose of this study was to identify antioxidants and rice fiber analogue composites from moringa, purple sweet potato and cassava. The experimental design used was a Completely Randomized Design (CRD) with 1 factor of flour type (A) with a combination of 3 levels of treatment, namely: A1 = Moringa flour 150g, purple sweet potato flour 100g and cassava flour 50g; A2 = Moringa flour 125g, purple sweet potato flour 75g and cassava flour 100g; A3 = Moringa flour 100g, purple sweet potato flour 125g and cassava flour 125g; A4 = Moringa flour 75g, purple sweet potato flour 100g and cassava flour 150g. Using a completely randomized design, four formulations with varying ratios of the three flours were evaluated for fiber content and antioxidant activity. The results revealed significant differences (p<0.05) in both attributes across formulations. The highest fiber content (3.55%) was observed in the formulation with 150 g purple sweet potato flour, 100 g moringa flour, and 50 g cassava flour, while the highest antioxidant activity (11.80%) was achieved using 100 g each of moringa and cassava flours and 50 g purple sweet potato flour. These findings underscore the potential of composite flours to produce analog rice with enhanced nutritional benefits, contributing to sustainable food security and local food innovation.

Abstract

The Merdeka Belajar Curriculum was launched by the Ministry of Education, Culture, Research, and Technology to improve the quality of education in Indonesia. This curriculum is designed to provide flexibility in learning, develop 21st-century skills, and instill the values of the Pancasila Student Profile. However, the implementation of the Merdeka Belajar Curriculum in Vocational High Schools (SMK) faces various challenges, such as limited resources, teacher readiness, and the involvement of the business and industrial sectors. This study aims to evaluate the implementation of the Merdeka Belajar Curriculum at SMK Negeri 2 Payakumbuh using the Context, Input, Process, and Product (CIPP) evaluation model. The evaluation was conducted to understand the application of the curriculum and identify its strengths, weaknesses, and improvement opportunities. This research uses a quantitative method with a structured approach to evaluate the implementation of the Merdeka Belajar Curriculum. Quantitative data were collected through the distribution of questionnaires designed to measure the four components of the Context, Input, Process, and Product (CIPP) evaluation model. The research sample includes teachers, students, and the principal at SMK Negeri 2 Payakumbuh who are involved in the curriculum implementation.. The research instruments consist of questionnaires, interviews, and observations designed to measure the four components of the CIPP model. The results show that the context, input, process, and product components of the Merdeka Belajar Curriculum implementation are generally good. However, the input component requires improvement, particularly regarding resource availability, ongoing teacher training, and strengthening collaboration with the business and industrial sectors. This study recommends that implementing the Merdeka Belajar Curriculum be continued by improving the input aspect through providing adequate resources, intensive teacher training, and strengthening partnerships with the business and industrial sectors to enhance curriculum relevance.
