Abstract

This study aims to obtain information about the use of Problem Based Learning model to increase students' cognitive abilities. The research method used is a quasi-experimental One Group Pretest-Posttest Design, with the research subjects of 31 students of class X at SMA Citra Bangsa Makassar. Students are divided into three categories of ability groups, namely: high, medium and low based on the average value of daily tests. The instruments used were multiple choice written tests, essays, observation sheets, and interview guide questionnaires. The increase in learning outcomes is calculated using the gain normalization formula and the average N-Gain relationship test. The results showed that this learning model showed a significant increase in student learning outcomes with an average N-gain percentage of 65.33% for all students. The highest increase in learning outcomes was achieved by students in the high category (N-gain = 68%). The students gave positive responses to learning, and they felt happy and motivated in participating in learning using the implemented learning model.

Abstract

The liver plays an important role in maintaining the homeostasis of an organism, if there is damage to the liver it will disrupt its function and be fatal. Liver damage caused by poisons, drugs, and all other possible causes can be protected by compounds containing flavonoids as antioxidants which have the potential to become hepatoprotectors. The purpose of this literature review is to discuss the antioxidant effectiveness of several plants that have the potential as hepatoprotectors. The method used in this review is based on literature studies from several scientific publications in national journals on the effectiveness of plants containing flavonoid compounds as antioxidants used for hepatoprotectors, which consists of 16 articles. The results used from several studies show the effectiveness of the plant with each dose that has been tested.
