Abstract

This study aims to describe students’ perceptions of the implementation of the Project -Based Learning (PjBL) model combined with the use of teaching aids in learning the human respiratory system in Grade XI at SMAN 1 Bunobogu. The study employed a descriptive qualitative approach. The research subjects consisted of three students purposively selected based on different levels of ability. Data were collected through participatory observation, in-depth interviews, supporting questionnaires using a Likert scale, and documentation. Data validity was ensured through source and method triangulation, while data analysis followed the Miles and Huberman model. The results indicate positive perceptions across all three aspects. The cognitive aspect showed a supporting questionnaire score of 3.56 (good category), and the teaching aids effectively transformed abstract concepts into more concrete representations. The affective aspect, with a score of 3.58, reflected increased learning interest and motivation. The psychomotor aspect, with a score of 3.53, contributed to the development of practical skills, creativity, and teamwork.

Abstract

Tropical forest ecosystems are home to diverse insect communities that play essential ecological roles, including pollination, decomposition, and nutrient cycling. Among the key forest plants, rattan (Arecaceae) provides both ecological and economic benefits and serves as an important microhabitat for various insect species. This study aimed to identify and analyze the diversity of insect species associated with natural rattan habitats in Namo Village, Kulawi District, Central Sulawesi, Indonesia. Insect sampling was carried out using sweep nets, pitfall traps, and yellow pan traps along rattan-dominated forest transects. A total of 125 individual insects were collected, representing 7 orders, 28 families, and 37 species. The order Hymenoptera showed the highest abundance (41.6%), dominated by Formicidae and Apidae families, followed by Coleoptera (25.6%) and Diptera (17.6%). The Shannon–Wiener Diversity Index (H’ = 2.84) indicated moderate species diversity with high evenness (E = 0.83). Functionally, the insect community consisted of pollinators (38.2%), herbivores (25.4%), decomposers (19.6%), and predators (16.8%). These findings demonstrate that natural rattan ecosystems support diverse and functionally balanced insect assemblages, reflecting stable ecological conditions and minimal anthropogenic disturbance. Conserving natural rattan stands is therefore crucial for maintaining biodiversity and sustaining ecological functions such as pollination and decomposition within tropical forest ecosystems.
