What is The learning models of essential oil with science technology engineering mathematic (STEM) approach integrated ethnoscience about?

## Abstract The topic of essential oil is one of the topics of the Natural Organic Chemistry course which discusses the meaning of essential oils and examples, isolation techniques and identification of essential oils, structural tests and the number of essential oil components. The next discussion was related to the engineering of the main compounds in essential oils, as well as the calculation of the yield of essential oil products. Learning of essential oils is still conventional, and less contextual, therefore in this study an essential oil learning with integrated science technology engineering mathematics (STEM) approach of ethnoscience and an integrated STEM approach of Ethonoscience has never been done by lecturers. This type of research is a qualitative descriptive study, the research subjects are the owners and workers in essential oil refining, with a focus on the reconstruction of Indegenous science based science knowledge and the design of the essential oil learning model with an integrated STEM approach to ethnoscience. Local essential oils used as research objects are clove oil, citronella oil, and traditionally produced patchouli oil. Data collection through intervi
