Abstract

Indonesia is known as a country with the highes biodiversity, including ferns (Pteridophyta), which are an important part of tropical flora. The Keumuning Protected Forest area in Langsa City, Aceh, covers approximately 1,050 hectares and serves as a natural habitat that supports the taxonomic diversity of ferns. This study aims to identify and document the diversity of fern species in the area to support biodiversity conservation and preservation efforts. The method used is exploratory descriptive, employing field survey techniques, as well as morphological identification based on literature and visual documentation. The results of the study indicate the presence of eight fern species belonging to six families and one taxonomic class, with a predominance of the Polypodiopsida class. The species found exhibit diverse morphological variations, playing a crucial role as environmental bioindicators and erosion control agents. These findings underscore the importance of the Keumuning Protected Forest as a natural habitat that plays a vital role in supporting biodiversity and its ecosystem. Therefore, protection, sustainable conservation, and enhanced public education are essential to ensure the long-term preservation of these ferns and the protected forest ecosystem.

Abstract

The order Diptera has various ecological roles, including as decomposers, pollinators, predators, disease vectors, and bioindicators of environmental quality. The University of Lampung area, consisting of green open spaces, building areas, and water bodies, provides diverse ecological niches for Diptera. This study aimed to identify species, calculate diversity indices, and analyze the relationship between environmental factors and Diptera diversity in the area. The research was conducted from December 2025 to January 2026 using a free roaming method with direct sweeping techniques. Sampling was carried out in the morning (08:00–10:00 WIB) and afternoon (15:00–17:00 WIB) using sweep nets, aspirators, and dippers. Data analysis included the Shannon-Wiener diversity index (H'), Evenness index (E), and Simpson index (D). The results showed a total of 835 individuals belonging to 15 families and 22 species of Diptera. The diversity index (H') was 1.868 (moderate), the evenness index (E) was 0.604 (moderate), and the dominance index (D) was 0.237 (low). These results indicate that the Diptera community is relatively stable without any dominant species. The average air temperature was recorded at 28.6 ℃ in the morning and 28.7 ℃ in the afternoon, while the humidity levels were 77.2% (morning) and 75.7% (afternoon).
