Abstract

The bangle plant (Zingiber montanum) is a plant that has been used traditionally as a medicinal ingredient, both for prevention and treatment by the community. Parts of the bangle plant contain active compounds that act as antioxidants, one of which is flavonoids. This research aims to determine the total flavonoid content in bangle plants from the extraction results measured using a UV-Vis spectrophotometer. The method for separating flavonoid levels used is maceration. The research results showed that positive test results were obtained for flavonoid compounds in bangle rhizomes as evidenced by qualitative test results which produced a red color in the sample extract and the average total flavonoid content in bangle rhizomes from the extraction results measured using a UV-Vis spectrophotometer was 23. 1mg/100g.

Abstract

Low understanding among teachers regarding the concepts and benefits of Classroom Action Research (CAR) as a means of professional development is one of the main problems at SD Negeri 2 Labuan. Most teachers are not yet accustomed to systematically reflecting on their teaching practices thru classroom-based research. This resulted in very limited teacher participation in CAR activities, and the learning innovations that were supposed to emerge from this process were also hindered. To address this, the Faculty of Education and Teacher Training at Tadulako University conducted a Community Service (PkM) activity to improve teacher competence thru training and the implementation of Classroom Action Research. This activity included training, mentoring in preparing CAR as well as reflection and evaluation. The evaluation results show an 84% increase in teachers' understanding of CAR. Full support from the school and active participation from the teachers also contributed positively to the success of this activity.
