Abstract

Abstrak Echinodermata berperan penting pada ekosistem terumbu karang sebagai bagian dari jejaring makanan. Mereka dapat bersifat herbivora, karnivora, dan/atau omnivora. Kerusakan terumbu karang di Pantai Meras akhir-akhir ini dapat mengancam Echinodermata. Informasi tentang diversitas Echinodermata di Pantai Meras masih sedikit. Oleh karena itu, penelitian tentang diversitas Echinodermata perlu dilakukan di Pantai Meras, Kecamatan Bunaken, Sulawesi Utara. Pengambilan sampel pada tiap lokasi dilakukan pada saat surut terendah dengan menarik 3 garis transek (masing-masing 100 meter) secara vertikal dari garis pantai ke arah laut. Petak kuadrat (1 x 1 meter) diletakkan dengan jarak antar kuadrat yaitu 10 meter. Hasil penelitian menunjukkan bahwa Echinodermata hidup pada habitat padang lamun, pasir dan terumbu karang baik yang hidup maupun mati. Total species yang ditemukan yaitu 8 spesies yang termasuk anggota dari 3 kelas. Kelas Asteroidea (bintang laut) sebanyak 3 spesies, Echinoidea sebanyak 4 spesies dan Kelas Holothuroidea sebanyak 1 spesies. Diversitas Echinodermata di Pantai Meras adalah antara rendah hingga sedang dengan nilai indeks diversitas Shannon-Wiener (H’) berkisar antara 0,48 – 1,31. Kata kunci: Diversitas Echinodermata, Pantai Meras, Sulawesi Utara Abstract Echinoderms have important role in coral reef ecosystems as part of the food webs. They may be herbivores, carnivores, and/or omnivores. Coral reefs destruction in Meras Beach lately can threaten Echinoderms. There was little information about Echinoderms diversity of Meras Beach. Therefore, research on Echinoderms diversity needs to be done on the Meras Beach, Bunaken District, North Sulawesi. Sampling was carried out at each location at the lowest tide. There were 3 line transects (each 100 meters) located vertically from the shoreline towards the sea. The square plots (1 x 1 meter) placed distance between plots was 10 meters. The results showed that Echinoderms occupied different habitat i.e. sea grass, sand, live and/or coral reefs. Total species found 8 species belong to members of the 3 classes. Asteroidea Class (starfish),  Echinoidea Class and Holothuroidea were respectively 3 species, 4 species and 1 species. Echinoderms diversity on the Meras Beach were low to moderate with Shannon-Wiener diversity index (H ') was 0.48 to 1.31.

Abstract

Sexing atau pemisahan spermatozoa adalah proses pemisahan spermatozoa yang membawa sifat kelamin jantan dan betina. Infertilitas merupakan satu kondisi dimana pasangan yang aktif secara seksual tanpa melakukan kontrasepsi tidak mampu mendapat kehamilan dalam kurun waktu selama 1 tahun. Sekitar 50-80 juta pasang suami istri di dunia (1 dari 7 pasutri) yang terkena masalah infertil dan pada setiap tahun muncul sekitar 2 juta pasangan suami istri infertil. Di Indonesia diperkirakan ada 4 juta sekian pasangan suami istri yang mengalami infertil atau ketidaksuburan. Solusi yang dapat dilakukan untuk mencegah dan menghindari kerusakan membran pada spermatozoa saat pemisahan spermatozoa adalah dengan menggunakan metode sentrifugasi dengan penambahan kuning telur. Penelitian ini bertujuan untuk mengidentifikasi dan menganalisis integritas membran spermatozoa pada proses sexing sebelum dan sesudah pemberian kuning telur. Metode yang digunakan adalah Rancangan Acak Lengkap dengan tiga perlakuan, yaitu kontrol, sentrifugasi, sentrifugasi + kuning telur. Hasil penelitian menunjukkan bahwa integritas membran yang termasuk destabilisasi membran dan disintegritas pada kontrol sebesar 18% dan 19%. Persentase perlakuan sentrifugasi yang termasuk destabilisasi membran dan disintegritas sebesar 57% dan 50%. Sedangkan persentase perlakuan sentrifugasi + kuning telur yang termasuk destabilisasi membran dan disintegritas sebesar 25% dan 31%. Perbedaan yang signifikan terlihat pada perlakuan sentrifugasi terhadap perlakuan yang lain.

Abstract

The city of Manado is surrounded by waters with a long coastline. Most of the coastline is used for human activities. These activities include tourist attractions, ports, and trade centres. The sustainability of these sectors is highly dependent on the health of the marine ecosystem. One organism that plays an important role in the aquatic ecosystem is zooplankton. This study aims to calculate the density of zooplankton and analyse its functional role. The method used was exploratory descriptive, which is a research pattern that describes in detail or comprehensively the condition or status of zooplankton phenomena. This study was conducted at Bahu Beach and Meras Beach, North Sulawesi. The density value at Bahu Beach is 307.35 ind/m3 and at Meras Beach is 222.4 ind/m3. Zooplankton identified from two sampling points belonged to the phyla Arthropoda, Foraminifera, Annelida, Mollusca, and Cilliophora. The total number of genera found was 22. There were 1,032 consumer I individuals, 798 consumer II individuals, and 193 consumer III individuals.

Abstract

Gastropods play an important role in maintaining the balance of coastal ecosystems, particularly as detritivores that support nutrient cycling. Pantai Meras, located in North Sulawesi, has a complex coastal ecosystem that includes mangrove forests, seagrass beds, and coral reefs, which support high biodiversity. However, information regarding gastropod diversity in this area remains limited. This study aims to identify gastropod species and analyze their diversity levels in the waters of Pantai Meras. A purposive sampling method was used for data collection, employing 0.5 m × 0.5 m plots placed randomly at 45 sampling points across three research stations with different substrate types, namely sandy substrate (Station 1), muddy sand substrate (Station 2), and sand mixed with coral fragments (Station 3). Data were analyzed using PAST software version 4.17 to calculate the Shannon diversity index (H’). The results showed a total of 243 gastropod individuals belonging to 89 species from six orders, with Neogastropoda being the dominant order, comprising 59 species. The most abundant species was Nassarius globosus, with a total of 26 individuals recorded. The overall Shannon diversity index (H') was 4.14, which falls into the high diversity category. The highest H' value was recorded at Station 1 (4.08), followed by Station 3 (4.02), and the lowest at Station 2 (3.43). The high gastropod diversity at Pantai Meras indicates that the coastal ecosystem in this area is still in good condition and capable of supporting sustainable gastropod populations. Environmental factors such as temperature, salinity, as well as the presence of mangroves, seagrass beds, and coral reefs contribute to the high species diversity of gastropods in the study area.
