SCIENTIFIC LITERACY OF SENIOR HIGH SCHOOL STUDENTS USING ETHNOSCIENCE BASED LEARNING CHEMISTRY Scientific literacy skills are needed to understand science issues, the risks, and benefits of science, and understand the nature of science, including its relationship to culture. This study aimed to determine students' scientific literacy in using ethnoscience-based learning-chemistry. The study Method used quasi-experimental by nonequivalent control group design. The subject was grade XI-MIPA of SMAN 1 Kendal. The data collection techniques are test instruments to know students' scientific literacy. The analysis data technique is descriptive and inferential statistical analysis (independent sample t-test and N-gain). The results showed that the ethnoscience based learning-chemistry could increase students' scientific literacy. The mean score of students' scientific literacy on experiment and control class was 72% (high category) and 65% (medium category), and count -3,551 and table -1,995. N-gain score experiment class of 0,47 (medium) and control class of 0,28 (low). Ethnoscience-based chemistry learning can be used in chemistry learning to develop students' chemical literacy skills. AbstrakKemampuan literasi sains dibutuhkan untuk memahami isu-isu sains, resiko dan manfaat sains, serta untuk memahami sifat sains, termasuk hubungannya dengan budaya. Penelitian ini bertujuan mengetahui kemampuan literasi sains siswa melalui pembelajaran kimia berbasis etnosains. Metode penelitian yang digunakan adalah quasi experimental dengan desain nonequivalent control group design. Subjek penelitian ini adalah siswa kelas XI MIPA SMAN 1 Kendal. Teknik pengumpulan data berupa tes untuk mengetahui kemampuan literasi siswa. Teknik analisis data menggunakan analisis deskriptif dan statistik inferensial (independent sample t-test dan uji N-gain). Berdasarkan hasil penelitian tersebut dapat dilihat bahwa pembelajaran kimia berbasis etnosains dapat meningkatkan kemampuan literasi sains siswa. Rerata skor kompetensi literasi sains siswa kelas eksperimen dan kontrol secara berturut-turut mendapat 72% dengan kategori tinggi dan 65% dengan kategori sedang, serta thitung sebesar -3,551, dan ttabelnya -1,995. Adapun nilai N-gain pada kelas eksperimen adalah 0,47 (kategori sedang) sedangkan kelas kontrol adalah 0,28 (kategori rendah). Pembelajaran kimia berbasis etnosains dapat digunakan dalam pembelajaran kimia untuk mengembangkan kemampuan literasi kimia siswa.
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.
Water is one of the natural wealth that is absolutely needed by living things to survive and maintain health. In facts, water treatment is carried out on the raw water that does not meet the standards of clean water quality, therefore, the non-standardized elements need to be eliminated or reduced so that all water meets the applicable standards. One alternative which is available locally is the use of natural coagulants from plants living around us. This research was conducted by students of the UNNES Postgraduate Chemistry Education Magister Program. The process for water treatment employedthepotentialnaturalcoagulantofmoringaseedextractusinganEthno-STEM approach.Thisresearchwascarriedoutasachemicalprojecttask,namelytheproject of using potential bio-coagulant of Moringa oleifera seeds or Moringa plant. In this study, tests were carried out on the use of bio coagulant of moringa seeds extract with various varieties to purify turbid water. The research results concluded that the magisters of chemistry education have been able to design and implement the integrated Ethno-STEM chemical project learning on water purification topic using moringa seed extract (Maringo oleifera). In addition, the findings indicated that the studentswereabletoreconstructethnical-basedscientificknowledgeinthecontextof STEM;andwaterpurificationexperimentswithbio-coagulantofMoringaseedextracts.
Critical and creative thinking is one of the 21st century skills that meet the needs in the educational process. In addition, learning local wisdom which is closely related to scientific concepts also really needs to be emphasized. This study aims to analyze students' critical and creative thinking skills through the application of Ethno-STEM Integrated Project Based Learning. This research is a case study research with a One-Shot Case Study design. The research subjects were 36 students of class XI IPA at SMA Negeri 1 Weleri. Data collection used a test instrument that has been validated by experts and shows a Cronbach Alpha score of 0.72. From the results of data analysis, it shows that students' critical thinking skills achieve good criteria, with the highest achievement in the aspect of providing simple explanations and the ability to think creatively of students achieving good criteria with the highest achievement on the flexibility aspect, which is to provide various interpretations of a picture, story, or problem. In conclusion, the integrated Ethno-STEM Project Based Learning can train students' critical and creative thinking skills.
