Abstract

Many rural communities have utilized Araceae plants for food, medicine, and ornamental purposes, yet scientific documentation of their diversity and relationships remains limited. This study aimed to analyze the morphological diversity and phenetic relationships among Araceae species in Lauru I Afulu Village, Indonesia. The research was conducted using a descriptive qualitative approach through field observations, interviews, and documentation, with species identified based on morphological characteristics. Data were analyzed using data reduction, classification, and comparative interpretation of morphological traits. The results showed that several genera of Araceae were identified, including Alocasia, Colocasia, Homalomena, Caladium, Aglaonema, and Schismatoglottis, exhibiting distinct variations in leaf shape, stem structure, and tuber characteristics. Species within the same genus demonstrated higher morphological similarity, indicating closer phenetic relationships, while intergeneric differences were more pronounced. A significant finding revealed a strong association between morphological traits and local utilization patterns. These findings highlight the importance of morphological analysis in understanding plant diversity and emphasize the value of integrating local knowledge with scientific approaches for biodiversity documentation and sustainable utilization.

Abstract

The low level of scientific reasoning skills and conceptual understanding among pre-service elementary school teachers remains a significant challenge in science education at the higher education level. This condition reflects a gap between students’ mastery of scientific theories and their ability to connect scientific concepts with instructional practices in primary education. This study aims to examine the perceptions of pre-service primary school teachers toward the Advanced Fundamental Science Concepts course in supporting their professional teaching competencies. The study employed a descriptive quantitative approach supported by qualitative data obtained through interviews. Data were collected using a questionnaire consisting of 20 validated and reliable statements, which was voluntarily administered to 36 students enrolled in the Primary Teacher Education Program. Data analysis was conducted using descriptive statistics in the form of percentages, while interview data were analyzed qualitatively to strengthen and enrich the research findings. The results indicate that students demonstrated positive perceptions toward the Advanced Fundamental Science Concepts course, particularly in terms of understanding fundamental science concepts (84%) and the relevance and application of science concepts (81%). The findings further reveal that students have recognized science as a scientific reasoning process; however, they continue to encounter difficulties in data analysis and scientific inference skills. Therefore, science education in teacher preparation programs should place greater emphasis on strengthening scientific reasoning competencies through inquiry-based and practice-oriented learning approaches.
