Abstract

The Indian Costus plant (Saussurea lappa) possesses the ability as an antibacterial, which contains alkaloid compounds, whereas this study aims to determine the antibacterial activity of ethanol extract of Indian Costus plant root (Saussurea lappa). The extraction process of Indian Costus plant root simplicia (Saussurea lappa) was carried out using the Soxhlet method with 96% ethanol as a solvent, and then evaporated with a rotavapor to obtain a viscous extract. Screening tests were carried out by giving ethanol extract of Indian Costus plant root (Saussurea lappa) with a concentration of 0.1% to 2 test bacteria, namely Staphylococcus aureus and Escherichia coli. Thereafter, the Thin Layer Chromatography-Bioautography test was carried out, followed by identification of chemical compounds. The screening test results obtained showed that the ethanol extract of Indian Costus plant root (Saussurea lappa) provided activity against 2 test bacteria at a concentration of 0.1%. The Thin Layer Chromatography-Bioautography test results indicated that there were 3 spots that were formed with Rf values of 0.67, 0.60, 0.54, 0.45, 0.43 providing activity on Staphylococcus aureus and Escherichia coli bacteria. The chemical identification of ethanol extract of Indian Costus plant roots (Saussurea lappa) yeilded positive result for the presence of alkaloids. Based on the activity of the ethanol extract of Indian Costus plant root (Saussurea lappa), it is known that it has potential as an antibacterial.

Abstract

This study aims to analyze the implementation of the Love Curriculum as a strategy to enhance ecological understanding among students of Madrasah Tsanawiyah. The research is motivated by the existing gap between students’ ecological knowledge and its practical application in daily life, where learning that focuses primarily on cognitive aspects has not fully succeeded in fostering ecological awareness and attitudes. The research method employed is a qualitative approach with a literature review design, involving the collection, examination, and analysis of various sources related to ecological education, character education, and the Love Curriculum. Data analysis was carried out using descriptive-analytical content analysis to identify the forms of Love Curriculum implementation, the obstacles encountered in its application, and its impact on students’ ecological attitudes. The findings reveal that the implementation of the Love Curriculum is realized through the integration of love values in subject learning, extracurricular activities, teacher role modeling, and school-based programs. The challenges identified include limited teacher understanding, lack of supporting facilities, low student participation, and insufficient support from the social environment. Nevertheless, the application of the Love Curriculum has shown a positive impact in shaping students’ ecological attitudes, both individually, collectively, and affectively.
