Abstract

Ekosistem lamun di kawasan pesisir saat ini banyak memperoleh ancaman dan tekanan dari kegiatan antropogenik. Perairan Teluk Lampung memiliki luas padang lamun sebesar 710 Ha pada tahun 2015. Dengan kondisi baik sebesar 64,79%, kondisi sedang sebesar 22,59% dan kondisi rusak sebesar 12,62 %. Lokasi kajian merupakan kawasan ekosistem lamun yang mendapat pengaruh langsung dari aktifitas budidaya keramba jaring apung, daerah penangkapan ikan dan kerang, kegiatan ekowisata mangrove dan daerah aliran sungai Desa Sidodadi. Penelitian ini bertujuan untuk mengetahui kondisi eksisting dan status ekosistem padang lamun kawasan perairan Ekowisata Mangrove Cuku Nyinyi. Metode sampling yang digunakan berdasarkan panduan monitoring padang lamun oleh LIPI dengan menggunakan kuadran 50x50 cm. Hasil penelitian menunjukkan bahwa kondisi kualitas perairan di lokasi kajian cukup sesuai untuk kelangsungan hidup dan perkembangan lamun. Berdasarkan hasil penelitian diperoleh dua jenis lamun yaitu Enhalus acoroides dan Thalassia hemprichii. Jenis E. acoroides memiliki rata-rata kerapatan sebesar 339 individu dan jenis T. hemprichii sebesar 104 individu. Persentase penutupan lamun tergolong dalam kategori sedang dengan dominansi jenis tertinggi pada E. acoroides. Berdasarkan nilai penutupan lamun dapat disimpulkan bahwa status padang lamun kawasan Ekowisata Cuku Nyinyi termasuk dalam kategori kurang kaya atau dalam kondisi kurang sehat.

Abstract

Fruit bats (family Pteropodidae) pollinate around 300 species of tropical plants of high economic value over a wide range of areas. This large role does not match the status of their population, which continues to decline due to habitat loss, particularly in urban areas. The Sumatra Institute of Technology (ITERA) campus, which is currently under development, may result in habitat changes that may affect bats. These concerns have led to the need for research into bat diversity on the ITERA campus. The result could be utilised to monitor and develop the environmental management of the campus. The research was conducted from May to September 2023 in five different habitat types. Data were collected using 3 mistnets and 3 night repetition each habitat. The data were analysed using indices of diversity, evenness and species richness. The study recorded 143 individuals of 7 species. The highest number of species and diversity was observed in the sengon and rubber habitat (6 species). The lowest number of species and diversity was found in the botanical garden (2 species).

Abstract

Mangroves as buffer ecosystems possess a natural capacity to trap pollutants originating from both terrestrial and marine sources, including microplastics. This study aimed to identify and map the characteristics and distribution of microplastics in the sediments of the Pasir Sakti mangrove ecosystem. The study employed a descriptive–quantitative approach combining laboratory and geospatial analyses. Sediment samples were collected from five stations using purposive sampling and analyzed through granulometric analysis, microplastic extraction using a NaCl solution, and morphological identification of microplastics using a microscope. Ecological parameters, including water quality and mangrove vegetation structure, were measured in situ. The distribution of microplastics was visualized as thematic maps using a Geographic Information System (GIS). The results of water quality analysis showed temperatures ranging from 29.7 to 31.9 °C, salinity of 9–11 ppt, relatively high water pH values of 8.76–10.8, acidic soil pH values of 3–6.7, low water transparency of 22–30 cm, and very high TDS concentrations of 6,825–7,967 ppm. The sediment at the study site was predominantly classified as sand. The mangrove vegetation was dominated by Avicennia sp., with a density ranging from 0.24 to 0.67 individuals/m². A total of 259 microplastic particles were identified, comprising film, fragment, foam, fiber, and pellet types. Film was the dominant microplastic type, with a total of 160 particles.
