Abstract

The use of plants as natural dyes represents important traditional knowledge of the Acehnese people, closely linked to cultural practices, crafts, and the use of local natural resources. However, modernization and synthetic dyes threaten the continuity of these traditions. This study aimed to examine the diversity of natural dye plants and their utilization patterns within Acehnese communities. A qualitative ethnobotanical approach was applied through field observations, semi-structured interviews with key informants, and documentation of dye-producing plant species. Data were analyzed descriptively by grouping plants based on parts used, colors produced, and forms of utilization. The findings show that various local plant species are used as natural dye sources, with leaves, bark, and fruits being the most commonly utilized parts. Utilization patterns are strongly connected to cultural needs and local wisdom in maintaining environmental balance. The study concludes that ethnobotanical knowledge of natural dyes persists despite modernization, highlighting its importance for preserving local knowledge and promoting environmentally friendly dye alternatives in cultural and applied science contexts.

Abstract

Science learning in elementary schools still faces the problem of students’ low conceptual understanding due to the dominance of conventional teaching methods that do not adequately connect concepts with real-life applications. This condition leads to difficulties for students in integrating scientific knowledge with technology, engineering, and mathematics. This study aimed to analyze the effectiveness of the STEM learning model on students’ conceptual understanding of science at the fifth grade of Bangun Insan Mandiri Elementary School. The research employed a quantitative approach using a quasi-experimental method with a pretest–posttest control group design. The research subjects consisted of two classes: an experimental class that implemented the STEM learning model and a control class that used conventional instruction. Data were collected through a science conceptual understanding test administered before and after the treatment. The data were analyzed using descriptive and inferential statistical techniques to determine differences in the improvement of conceptual understanding between the two groups. The results showed a significant increase in science conceptual understanding among students who learned through the STEM learning model compared to those in the control class. The STEM learning model effectively encouraged students to develop a deeper understanding of science concepts through problem-solving activities, simple design processes, and the application of concepts in real-world contexts. Therefore, the STEM learning model is effective for improving fifth-grade students’ science conceptual understanding and can be used as an innovative instructional strategy in elementary science education.
