Abstract

The training is descriptive research that describes the results of implementing the Virtual Chemistry Lab for all prospective chemistry teachers, as well as general science skills. The research subjects for this topic are second and third year chemistry students who have completed basic chemistry courses. This activity lasted for two days and began with the introduction stage of the Chemcollective Virtual Chemistry Lab software, then continued with the implementation stage, especially the application of the use of the Virtual Chemistry Lab and evaluation of its implementation. The results obtained show that students' ability to apply software is quite good and their ability to acquire general scientific skills is around 80% and student responses are very positive at 89%.

Abstract

The local wisdom of the indigenous people of the Byak tribe of Kampung Yendidori in utilizing the leaves of red hibiscus (the local name of the leaves "Penbrike") as an herb for mothers after childbirth shows rich empirical knowledge and is relevant to modern chemical concepts. This research aims to integrate an ethnographic perspective based on a mental model in describing the cultural significance of this practice and explaining the content of active compounds in these plants through macroscopic, submicroscopic, and symbolic level approaches. This type of research is qualitative with an ethnographic approach based on mental models. The results obtained show the sacredness of the use of "Penbrike" leaves. The community believes that treatment is effective if it is carried out by the clan or the person appointed to inherit its use. The results of a literature review show that the main content in its leaves is alkaloids, tannins, flavonoids, steroids, saponins, phenols, proanthocyanidins. The active compounds in this plant function as powerful antioxidants that help reduce oxidative stress and postpartum inflammation, some accelerate hemostasis and wound recovery, and some provide vasoconstriction and protein binding effects and help stop bleeding. However, based on the results of other literature reviews, it was found that hibiscus leaves contain anti-fertility compounds, so further research is needed. These studies can serve as a basis for the development of ethnoscience-based chemistry learning models and further research on ethnopharmaceuticals.
