Abstract

Background: Biology is a pure science that is analytical and systematic. It relates to the reality of the problems experienced by students in the current biology learning process, which is a monotonous way of learning and tends to make students feel bored with the learning process carried out, so that the teaching material delivered by the teacher or educator is difficult to understand by students. This class action research aims to improve student learning motivation on Biodiversity material. Methods: This class action research was conducted in two cycles; the first cycle was carried out with one meeting and the second cycle was carried out with one meeting. Each cycle is the application of Kemmis and Mc Taggart's classroom action research consisting of 4 stages: planning, action, observation, and reflection. Results: The results of this study are an increase in learning motivation of students in each cycle. Conclusions: Based on these results, it can be concluded that the Motion Graphics learning media based on e-learning has succeeded in increasing students' learning motivation on Biodiversity material.

Abstract

Background: Indian almond (Terminalia catappa) is used as an alternative medicine by the community to treat various diseases. However, limited research has been conducted on the subchronic toxicity of Indian almond water extracts on the liver. Present study aimed to determine the subchronic toxic effects of Indian almond leaf water extract on the liver histology of mice and to evaluate the safe dose of Indian almond leaf water extract with various doses (125, 250, 500, 750 and 1000 mg/kg). Methods: In total of 33 male mice were randomly divided into 11 groups, each group consisting of three mice as replication. For 30 days, mice in five treatment groups were orally treated every day with water extracts of green Indian almond leaf while other five groups were given water extracts of brown Indian almond leaves and compare with control group. At the end of day 30, all mice were sacrificed, and hepar was taken out for histological preparations. The histopathological changes in the liver was observed and assessed based on histological damage in the term of degeneration and necrosis. Results: The administration of green and brown Indian almond water extract at doses of 125, 250, 500, 750 and 1000 mg / kg BB showed a toxic effect on the liver of mice. The toxic effect was due to the high doses, causing a cell swelling damage and increased liver necrosis.
