Abstract

Spesies Tripneustes gratilla merupakan bulu babi yang termasuk anggota dari kelas Echinoidea. Hewan ini dapat ditemukan di ekosistem intertidal dan tergolong sebagai biota bentik yang sering ditemukan di ekosistem terumbu karang dan padang lamun. Spesies T. gratilla memiliki nilai ekologis yang penting dalam menjaga keseimbangan ekosistem laut, yaitu sebagai herbivor dan juga sebagai spesies kunci yang mampu mengendalikan pertumbuhan makroalga yang hidup di ekosistem terumbu karang. Tujuan dari penelitian ini adalah menentukan pola distribusi dan kepadatan populasi T. gratilla di ekosistem intertidal Pantai Bilik Taman Nasional (TN) Baluran. Metode menentukan pola distribusi dilakukan metode transek plot sistematis dengan cara meletakkan plot paralon berukuran 1x1 m di sepanjang transek garis. Pola distribusi T. gratilla di ekosistem intertidal Pantai Bilik TN Baluran tergolong mengelompok berdasarkan hasil analisis menggunakan Indeks Morisita dengan nilai Id sebesar 4.8. Kepadatan T. gratilla di ekosistem intertidal Pantai Bilik TN Baluran tergolong rendah dengan nilai kepadatan 0.2 Ind/m2 atau apabila dikonversikan maka hanya ada 2 individu dalam area plot seluas 10 m2. Tripneustes gratilla is a sea urchin that belongs to the class Echinoidea. These animals can be found in intertidal ecosystems and are classified as benthic biota which are often found in coral reef and seagrass ecosystems. The species T. gratilla has an important ecological value in maintaining the balance of marine ecosystems, namely as a herbivore and also as a key species capable of controlling the growth of macroalgae that live in coral reef ecosystems. The purpose of this study was to determine the pattern of distribution and population density of T. gratilla in the intertidal ecosystem of Bilik Beach, Baluran National Park. The method of determining the distribution pattern is carried out using the systematic plot transect method by placing 1x1 m paralon plots along the line transects. The distribution pattern of T. gratilla in the intertidal ecosystem of Bilik Beach, Baluran National Park, is classified as clustered based on the results of an analysis using the Morisita Index with an Id value of 4.8. The density of T. gratilla in the intertidal ecosystem of Bilik Beach, Baluran National Park, is low, with a density value of 0.2 Ind/m2 or when converted, there are only 2 individuals in a plot area of 10 m2.

巴卢兰国家公园比里克海滩潮间带生态系统中海胆（Tripneustes gratilla Linnaeus, 1758）的分布模式和种群密度。

玉米饼品种是由埃奇诺克人组成的海胆。这种动物可以在intertidal生态系统中找到，被归类为珊瑚礁和海草生态系统中常见的benta。象船队在维持海洋生态系统平衡方面具有重要的生态价值，它们既是一种食草动物，也是控制珊瑚礁生态系统的关键物种。这项研究的目的是确定海岸生态系统公园外的玉米饼的分布模式和密度。分配模式的方法是系统地横向图，将1x1 m的paralon图沿着横线放置。ba包括先生公寓内生态系统的T. gratilla分布的模式是基于使用形态索引的4.8 Id的分析结果。巴威德先生的海滩间生态系统的T. gratilla被归类为0.2平方小时/m2的密度，或者在面积为10平方英尺的土地内只有2个人。Tripneustes是属于Echinoidea类的海洋珍珠。这些动物可以在珊瑚礁和海洋系统中找到的秘密生物。象群有一个重要的生态价值，可以追溯到海洋生态系统的平衡，作为一种食草动物和其他关键的控制物种的生长。这项研究的目的是确定T. gra船队在国际海滩生态系统系统中央公园的分布和人口模式。确定的模式传播方法已经被采用了sys主题情节通过1x1 m的花边花纹传播。区域模式:跨国公园公园公园的玉米圆公园的牙齿密度很低，当10平方英尺的地块只有2个个体。

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.
