Analysis of Student Responses to Downstream of the Inquiry Learning Model Integrated Ethno-STEM for Aroma Compounds from Indonesian Herbal Tea to Give a Conservation Character

Abstract

This research is related to downstream research from an innovative learning model. This research aims to (a) downstream the Ethno-STEM integrated inquiry learning model, (b) analyze the profile of aroma compounds from herbal tea extracts in Indonesia, and (c) analyze student responses to the downstream of the Ethnoscience and STEM (Ethno-STEM) integrated inquiry learning model. STEM). Research was conducted at the Faculty of Mathematics and Natural Sciences. The research subjects were students of chemistry education at UNNES for the 2022/2023 academic year. The research instruments consisted of questionnaires, questionnaires, and observation sheets from the test results of Indonesian herbal tea aroma compounds. In this research the trapping of tea aroma compounds uses Arduino sensors. Data obtained from questionnaires and data on Indonesian herbal tea aroma compounds were analyzed descriptively qualitatively and quantitatively. The results of the research concluded that (a) the integrated Ethno-STEM inquiry learning model that was down streamed was the Sudarmin syntactic model, (b) Indonesian herbal tea aroma compounds consisted of hydrogen compounds, propane, carbon monoxide (CO), alcohol, carbon dioxide (CO2), toluene, ammonia, acetone, heptane, and sulfuric acid gas, and (c). students respond well to the integrated Ethno-STEM inquiry learning model that was developed, and this model is able to increase the Conservation character.
