Abstract

The application of the flipped classroom learning model with an ethnoscience approach trains students to learn independently in developing and sharpening critical thinking skills. The aim of the research is to determine the effect of the flipped classroom learning model with an ethnoscience approach on students' critical thinking abilities. This type of research is a quasi-experiment with a non-equivalent control group design. The sample used consisted of two classes, one class was designated as the experimental class and one class as the control class. The purposive sampling method was used to collect samples. The results of hypothesis testing using the t test show that t count is greater than table at a significance level of 0.05, which indicates that the hypothesis H0 is rejected. Thus, the flipped classroom learning model with an ethnoscience approach influences students' critical thinking abilities.

Abstract

This research is motivated by the low level of science literacy among students in Indonesia, including at SMP Negeri 17 Kota Jambi. The study aims to determine the effect of the STEM-based PBL model on the science literacy of seventh-grade students at SMP Negeri 17 Kota Jambi. This type of research is a quasi-experiment with a pre-test post-test control group design. The research sample consisted of two classes: the experimental class (VII C) with 32 students who received the STEM-based PBL model treatment, and the control class (VII E) with 31 students who used the direct instruction model.  The research results science literacy skills improved, with an average pre-test score of 58.5 and a post-test score of 79.75, while the control class increased from 38.32 to 60.38. The N-Gain value for science literacy in the experimental class was 50.83 (moderate category), which was higher than the control class's 38.32. The t-test results show a significance value of 0.037 < 0.05, which means there is a significant difference between the two groups. It can be concluded that the implementation of the STEM-based PBL model is effective in improving students' science literacy skills in science learning.

Abstract

Phaleria macrocarpa (Scheff.) Boerl., referred to as Mahkota Dewa, is a valuable medicinal plant with significant economic importance, requiring effective propagation methods to enhance its cultivation. Grafting is a frequently utilized technique, and its effectiveness is affected by the kind of growth medium used. This study aimed to evaluate the effect of different planting media on root growth of grafted Mahkota Dewa. The research was carried out between January and March 2026 in Lubuk Minturun, employing a Completely Randomized Design (CRD) with three different treatments: soil (P0), sawdust (P1), and cocopeat (P2), each consisting of six replications. The parameters monitored included the number of roots, root length, and dry weight of roots. Data were evaluated by using analysis of variance (ANOVA). The findings showed that the type of growth medium did not have a significant impact (p>0.05) on any of the root growth parameters measured. These results imply that alternative mediums like sawdust and cocopeat can serve as replacements for soil without notably hindering root growth in grafted P. macrocarpa.

Abstract

Local community knowledge about the utilization of plants in traditional ceremonies is a cultural heritage that is vulnerable to extinction due to modernization. Koto Malintang Village, located in the Lake Maninjau area, Agam Regency, West Sumatra, still strongly adheres to customs and traditions but has not been scientifically documented regarding the use of plants in its traditional ceremonies. This study aimed to identify the plant species, plant parts used, and how they are utilized in traditional wedding ceremonies in Koto Malintang Village. This descriptive research with qualitative and quantitative approaches was conducted from December 2025 to April 2026. Data collection was carried out through semi structured interviews with 20 key informants consisting of panghulu, bundo kanduang, niniak mamak, community members involved in ceremonial processes, and elders, as well as direct observation and documentation. Data analysis used Use Value (UVs), Relative Frequency of Citation (RFC), and Plant Part Value (PPV). The results found 35 plant species from 20 families utilized in wedding ceremonies. The Zingiberaceae family was the most dominant. Leaves had the highest percentage of utilization (29,27%). The highest UVs value was found in turmeric rhizome (Curcuma longa L.) at 3,50 and the highest RFC value was found in betel (Piper betle L.) at 1,00. Plants are used as traditional equipment and traditional food ingredients. This study documents the richness of local ethnobotanical knowledge that needs to be preserved and serves as a basis for further research.

Abstract

Objective: Develop students' argument skills through biology learning based on the STEM-RANDAI model. This model integrates six phases (reciting, analyzing, narrating, doing the solution, assessing, and implementing), so that students not only learn science concepts, but also build evidence-based arguments through collaborative and contextual activities. Method: This study adopted a quasi-experimental design with a Nonequivalent Control Group Design involving three groups (experimental class, positive control class and negative control class) to compare the results (posttest) between the three groups after the treatment was given. The goal is to apply the STEM-RANDAI model and develop innovative biology learning tools to improve students' argument skills. Results: The findings of the study show that there is a significant influence of the STEM-RANDAI learning model on the improvement of argumentation skills with a significance value of p = 0.000 (p < 0.001). Novelty: The novelty of this research lies in the RANDAI (Culture-based learning) model integrated with the STEM approach (STEM-RANDAI model) which is explicitly adapted to the context of West Sumatra high schools, Indonesia. The integration of cultural values in this learning model makes model innovation that is relevant to the needs of the 21st century, as well as unique by combining the two to create a model that addresses the gap in argument skills of students in West Sumatra, Indonesia.
