Abstract

Tropical coastal ecosystems possess high biodiversity and play a vital role in maintaining ecological functions, supported in part by the presence of sponges (Porifera) as filter feeders. This study aimed to identify species diversity, calculate ecological indices, and analyze the distribution patterns of sponges in the coastal waters of Labuan Beropa, South Konawe. Field surveys were conducted through sponge sampling at several observation sites, followed by taxonomic identification, calculation of Shannon-Wiener diversity index (H’), evenness (E), dominance (C), and distribution pattern analysis using the Morisita index. Seven benthic sponge species were recorded: Aaptos pernucleata, Aaptos suberitoides, Clathria (thalysias), Haliclona cymaeformis, Hyrtios erectus, Mycale sp., and Xestospongia muta. The highest density occurred in areas with stable rocky substrates, calm currents, and low anthropogenic disturbance, while the lowest density was observed in areas with intense human activities. H’ values were low (0.632–0.735), E values were high (0.748–0.869), and C values were low (<0.3). Distribution patterns were predominantly clumped, with some species exhibiting uniform or random patterns. These findings indicate that habitat physical quality and the degree of anthropogenic pressure are key determinants of sponge community structure. The baseline data generated can be used to support sustainable management and conservation of tropical coastal ecosystems.

Abstract

The waters of Koroe Onowa Village, Wakatobi Regency, are at risk of plastic waste contamination due to human activities on land that are carried by currents into the waters. Plastic waste is very dangerous for the health of the aquatic environment, especially marine biota, because the accumulation of microplastics over a long period of time can interfere with the respiratory and digestive tracts of marine biota, and has the potential to harm human health. For this reason, research on microplastics in these waters is needed. This study aims to analyze the abundance and distribution of microplastics in the waters of Koroe Onowa Village. Microplastic sampling was carried out using a modified plankton net method, which was then identified based on the type of microplastic. The results of the study showed that there were four main types of microplastics identified, namely fragments, films, fibers, and pellets, with an abundance ranging from 3.2 to 8.86 particles per liter. Station III, which is a coastal tourism area with dense human activity, showed the highest abundance value, namely 8.86 particles/liter. The results of this study provide an initial overview of the threat of microplastic pollution in the waters of Koroe Onowa and form the basis for better monitoring and waste management efforts in the area, as well as the need for mitigation measures to protect marine ecosystems and ensure the sustainability of coastal resources.

Abstract

Kelurahan Sambuli Kecamatan Nambo Kota Kendari memiliki potensi sumberdaya perikanan yang melimpah, namun tidak diimbangi oleh kreatifitas masyarakat dalam olahan poduk perikanan. Kegiatan pengabdian kepada masyarakat melalui Program Pengabdian Kepada Masyarakat Terintegrasi Kuliah Kerja Nyata - Tematik (PKM-KKN Tematik). Kegiatan pengabdian bertujuan untuk meningkatkan kesejahteraan masyarakat nelayan dan mengembangkan ekonomi lokal berbasis kelautan dan perikanan. Kegiatan ini dilakukan melalui pelatihan membuat berbagai produk olahan makanan berbahan dasar ikan sehingga nilai jual (nilai ekonomi) dari produk perikanan meningkat. Kegiatan ini dihadiri oleh kelompok nelayan Maju Jaya dan masyarakat setempat. Hasil yang telah dicapai pada kegiatan ini, yaitu kelompok nelayan dan masyarakat setempat telah memahami metode pengolahan, pengemasan, pemasaran dan pembukuan produk olahan ikan, serta telah berhasil membuat produk olahan dalam kemasan yang siap untuk dipasarkan.
