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.

Abstract

Araceae are herbaceous plants belonging to the monocotyledonous group of Angiosperms. They exhibit distinct morphological characteristics in their roots, stems, and leaves, and are generally herbaceous, with plant heights ranging from 90 to 180 cm. These plants hold significant economic and ecological value, as they are utilized as ornamental plants, food sources, and medicinal resources. This study aimed to identify and analyze the density of Araceae in the river basin area of Lawua Village, South Kulawi District, Sigi Regency. The research employed a descriptive qualitative and quantitative approach, with sampling conducted using the belt transect method across three different observation stations. Observations involved counting and recording the number of individuals of each Araceae species within the transect paths. Additionally, each species was documented, and samples were collected for identification based on their morphological characteristics, followed by density analysis. Overall, the study identified 16 Araceae species across 11 genera. These genera include: Alocasia (1 species), Colocasia (3 species), Dieffenbachia (1 species), Epipremnum (1 species), Homalomena (1 species), Pistia (1 species), Rhaphidophora (1 species), Scindapsus (2 species), Schismatoglottis (3 species), Spathiphyllum (1 species), and Syngonium (1 species). The overall density ranged from low to moderate, between 7 and 1,737 individuals, with abiotic conditions including an average temperature of 28 °C, humidity of 62.33%, light intensity of 2,998 Cd, and soil pH of 5.9. These findings provide valuable baseline data for the conservation and sustainable management of Araceae species in tropical riverine ecosystems.
