Abstract

This research aims to develop chemistry project-based learning with an Integrated Ethnoscience Approach in Science, Technology, Engineering, and Mathematics (Ethno-STEM) to improve students' conservative and entrepreneurial character. The research method refers to the Research and Development (R&D) model with the Four D by Thiagarajan (1997). The research samples are chemistry education students from Universitas Negeri Semarang. The model effectiveness test was conducted in secondary metabolite lectures at the Department of Chemistry, Faculty of Mathematics and Natural Science, Universitas Negeri Semarang, Indonesia. Data collection techniques used expert validation sheets to assess the feasibility of the model and observation sheets and questionnaires to measure students' conservative and entrepreneurial character. Based on the results of research, it was concluded that a chemical project-based learning model for the secondary metabolites course on essential oils and terpenes and learning tools with an Ethno-STEM approach was feasible and effective for improving students' conservative and entrepreneurial character with moderate and high criteria based on the N-gain score. The chemical batik motif on canvas based on the secondary metabolites' chemical structure is attractive and creative.

运用民族stem方法进行化学项目式中学代谢物课程学习，提高21世纪学生的保守性和创业性

本研究旨在发展以科学、技术、工程、数学为基础的综合民族科学方法的化学项目学习，以提高学生的保守性和创业性。研究方法参照Thiagarajan(1997)的四个D研究与开发(R&D)模型。研究样本为三宝垄大学化学教育专业的学生。模型有效性测试在印度尼西亚三宝垄大学数学与自然科学学院化学系的次生代谢物讲座中进行。数据收集技术使用专家验证表来评估模型的可行性，并使用观察表和问卷来衡量学生的保守性和创业性。基于研究结果，基于化学项目的精油和萜烯二级代谢物课程学习模式和基于Ethno-STEM方法的学习工具对于提高基于N-gain评分的中高标准学生的保守性和创业性是可行和有效的。基于次生代谢物化学结构的帆布化学蜡染图案具有吸引力和创造性。

期刊介绍： JOTSE is an international Journal aiming at publishing interdisciplinary research within the university education framework and it is especially focused on the fields of Technology and Science. JOTSE serves as an international forum of reference for Engineering education. Teaching innovation oriented, the journal will be issued twice per year (every 6 months) and will include original works, research and projects dealing with the new learning methodologies and new learning supporting tools related to the wide range of disciplines the Engineering studies and profession involve. In addition, JOTSE will also issue special numbers on more technological themes from the different areas of general interest in the industrial world, which may be used as practical cases in classroom tuition and practice. Thereby, getting the working world reality closer to the learning at University. Among other areas of interest, our Journal will be focused on: 1. Education 2.General Science (Physics, Chemistry, Maths,…) 3.Telecommunications 4.Electricity and Electronics 5.Industrial Computing (Digital, Analogic, Robotics, Ergonomics) 6.Aerospatial (aircraft design and building, engines, materials) 7. Automotive (automotive materials, automobile emissions).
