Abstract

Learning physics, especially rotational dynamics, is often difficult for many students because of the complexity of the concepts and abstract approach. In situations like this, conventional physics learning often encounters obstacles to providing in-depth understanding to students. Transformation in the world of education is becoming increasingly important, significantly increasing student motivation in studying physics so that it can improve students' performance. To address this issue, open-source blended learning materials that include problem-based learning (PBL) in the Rotational Dynamics curriculum must be developed. The goals of this study are to identify the phases involved in the creation of learning media; identify appropriate standards for learning media; and assess the usefulness of the learning media under development. The development model known as ADDIE is the process utilized for development. Four experts validated the blended learning media developed and underwent revisions to obtain suitable results. This research shows that: the learning materials created have been deemed legitimate and fit for use in the educational process, with a very high category; The application of the learning materials created is user-friendly and practical, also with a very high category.

Abstract

One of the significant danger factors for cardiovascular disease and stroke is dyslipidemia. According to long-term prospective epidemiological research, coronary heart disease is less common in those with good lipid profiles who lead better lives. In this study, on a high-fat diet, female wistar rats (Rattus norvegicus) will be tested and analyzed to see if green tea extract (Camellia sinensis) can prevent dyslipidemia when given orally. Compared to a control group that received only distilled water, the trial group that received 5 milliliters of green tea extract (Camellia sinensis) had significantly lower total and LDL cholesterol levels and higher HDL cholesterol levels. This treatment was more effective in lowering cholesterol overall. The components found in green tea (Camellia sinensis), including tannins, steroids, alkaloids, saponins, and flavonoids, can induce this. When certain bioactive substances are off, the body can bring them back into normalcy. These results suggest that white wistar rats (Rattus norvegicus), given a high-fat diet, can benefit from green tea (Camellia sinensis) extract to avoid dyslipidemia. Your lipid profile can be improved by ingesting green tea extract. The primary polyphenol in tea, catechin, is responsible for this transformation. Therefore, the Camellia sinensis plant, from which green tea is made, is a valuable plant that can halt or slow the progression of several ailments, including hypertension, metabolic disorders, and cardiovascular disorders.

Abstract

This research is focused on outlining experiences in rural human resource management through the introduction of a new professional farmer training process. The aim is to provide insights and references for developing countries in implementing farmer training and improving their human resource structure. The research methodology explores the literature combined with an inductive approach to describe and analyse experiences and lessons learned during training programmes to strengthen human resource capacity in the agricultural sector. The results of this study emphasise the importance of new professional farmer training in rural human resource management, with the Indonesian government prioritising the entire training process. The Indonesian government has taken strategic steps in farmer training, which include identifying appropriate training targets, selecting influential investment entities, developing practical training models, and designing supportive policies. These initiatives have significantly improved the quality and structure of rural human resources. The uniqueness of this research lies in its selection of topics that are less widely covered in the literature, especially regarding the training process and the new professional farmer model. This research is also important in enhancing the skills of rural individuals, increasing farmers' income, strengthening the role of agriculture, and supporting economic growth in rural areas. Furthermore, this research makes a significant contribution to the literature by enriching the theory of human capital investment in rural areas.
