Abstract

Pulau Nyamuk ialah pulau dengan keanekaragaman hayati salah satunya adalah ekosistem lamun. Pentingnya peran ekosistem lamun pada perairan laut menimbulkan pertanyaan mengenai kondisi padang lamun di Pulau Nyamuk Karimunjawa. Hal ini diperlukannya penambahan informasi mengenai kondisi ekosistem lamun di kawasan Pulau Nyamuk, menyebabkan perlunya pembaruan informasi lamun. Tujuan penelitian untuk mengetahui spesies lamun dan struktur komunitas. Metode yang digunakan dalam menentukan lokasi sampling yaitu purposive sampling. Metode pengambilan data mengacu pada metode line transek menggunakan transek kuadran ukuran 50x50cm dengan jarak 50 meter antara line dengan panjang line transek 100 meter tegak lurus dari garis pantai ke arah laut. Hasil penelitian menunjukan jenis lamun yang dijumpai teridentifikasi sebanyak 4 spesies, kerapatan yang jarang, dengan tutupan yang tergolong kurang sehat. nilai frekuensi kelas A (0-20) dan Indeks Nilai Penting tertinggi pada jenis E. acoroides, dengan demikian jenis tersebut memiliki peranan paling penting dalam komunitas perairan di Pulau Nyamuk. Nyamuk Island is an island with biodiversity, one of which is the seagrass ecosystem. The importance of the role of seagrass ecosystems in marine waters raises questions about the condition of seagrass beds on Nyamuk Island, Karimunjawa. This requires additional information regarding the condition of the seagrass ecosystem in the Nyamuk Island area, causing the need for updating seagrass information. The study aims to determine seagrass species and community structure. Purposive sampling method is used in this research. The data collection method refers to the line transect method using a quadrant transect measuring 50x50cm with a distance of 50 meters between lines and a transect line length of 100 meters perpendicular from the shoreline to the sea. The results showed that the types of seagrasses found were identified as many as 4 species, rare density, and the cover was classified as unhealthy. the frequency value of class A (0-20) and the Important Value Index for the E. acoroides species, thus this species has the most important role in the aquatic community on Nyamuk Island.

尼亚穆克岛是一个生命多样的岛屿,其中之一是一个古老的生态系统。重要的是,海洋生态系统的作用引起了人们对尼亚穆克-卡里蒙贾瓦岛海洋环境状况的质疑。这需要关于尼亚穆克群岛地区古代生态系统状况的更多信息,从而需要更新古代信息。研究的目的是找出古老的物种和群落结构。用于确定采样位置的方法是有目的的采样。数据采集法是指使用50x50cm正方形样带的样带线法,样带线长度为100米,从海岸线一直延伸到大海。研究表明,有四种羔羊已被确认为稀有品种,其健康覆盖率较低。A类频率值(0-20)和橡实E.acoroides的最高重要值指数,因此该类型在尼亚穆克岛的水群落中发挥着最重要的作用。NyamukIsland是一个拥有生物多样性的岛屿,海草生态系统就是其中之一。海草生态系统在海水中作用的重要性引发了人们对卡里蒙贾瓦尼亚穆克岛海草床状况的质疑。这需要关于尼亚穆克岛地区海草生态系统状况的更多信息,因此需要更新海草信息。本研究旨在确定海草的种类和群落结构。本研究采用目的性抽样方法。数据收集方法是指使用50x50cm的象限样带和从海岸线到海洋垂直的100米的样带线长度的样带法。结果表明,所发现的海草种类多达4种,密度较低,被归类为不健康海草。A类(0-20)的频率值和E.acoroides物种的重要价值指数,因此该物种在尼亚穆克岛的水生群落中具有最重要的作用。

期刊介绍: The Journal of Marine Research publishes peer-reviewed research articles covering a broad array of topics in physical, biological and chemical oceanography. Articles that deal with processes, as well as those that report significant observations, are welcome. In the area of biology, studies involving coupling between ecological and physical processes are preferred over those that report systematics. Authors benefit from thorough reviews of their manuscripts, where an attempt is made to maximize clarity. The time between submission and publication is kept to a minimum; there is no page charge.
