Abstract

This study explores ethnoscientific practices surrounding Lansano (Pterocarpus indicus Willd.), a medicinal plant traditionally used in West Sumatra, Indonesia. Qualitative ethnographic methods, including direct observation and semi-structured interviews, were used with 50 respondents from various regions, including Padang, Pariaman, Solok, Sijunjung, Pasaman, Padang Panjang, and Pesisir Selatan. Participants included local healers, herbal practitioners, and community members known to use Lansano for medicinal purposes. This study employed a quantitative ethnobotanical approach with two main parameters: Use Value (UV) and Informant Consensus Factor (ICF). This study revealed a significant relationship between traditional practices and scientific evidence in the use of Lansano as an herbal medicine. This study is the first step in integrating Lansano ethnobotanical practices with bioactive data for the development of local culture-based phytopharmaceuticals. Use Value (UV) analysis showed that the leaves had the highest utilization value (UV = 0.70), followed by the roots (0.44), sap (0.36), and stems (0.30). Meanwhile, Informant Consensus Factor (ICF) analysis showed a complete consensus (ICF = 1.00) among informants regarding the use of lansano for various ailments, with the highest frequency of use for mouth ulcers, followed by diarrhea, menstrual pain, and burns. These results confirm that lansano has high ethnopharmacological value and is widely believed to be a primary traditional medicine in West Sumatra.

Abstract

Plant Physiology Education often faces challenges in visualizing complex internal and conceptual processes, such as photosynthesis, transpiration, and mineral nutrition. Traditional teaching methods often fail to motivate students and facilitate in-depth understanding. Investigation of AR and VR Technologies in Plant Physiology Education. This study employed a quantitative methodology with a descriptive design and correlational analysis, involving 50 students who completed a questionnaire regarding their motivation and comprehension of interactive digital books utilizing Augmented Reality (AR) and Virtual Reality (VR). The findings indicated a substantial enhancement in students' motivation and comprehension following the utilization of this technology. The Pearson correlation test indicated a positive link between students' motivation and comprehension, with a significance level of p-value <0.01. The t-test further validated a significant disparity in students' motivation and comprehension when utilizing AR and VR. This technology facilitates a more dynamic and immersive learning experience, aiding students in comprehending complex principles of plant physiology that are challenging to grasp through traditional techniques. This study advocates for the utilization of augmented reality (AR) and virtual reality (VR) technologies to enhance the quality of education in biology, particularly in the area of plant physiology
