Yuniar, Seananda Firly (2017) Kajian Kondisi Lamun Terkait Dengan Kelimpahan Gastropoda Untuk Menunjang Restorasi Lamun Di Pulau Pramuka, Taman Nasional Kepulauan Seribu, DKI Jakarta. Sarjana thesis, Universitas Brawijaya.
Abstract
Lamun mempunyai beberapa fungsi penting di daerah pesisir. Banyak organisme yang bergantung pada keberadaan lamun. Salah satu biota yang juga memberikan manfaat bagi lamun adalah gastropoda. Kegiatan wisata dan pembangunan di Pulau Pramuka menghasilkan banyak sampah serta menjadi ancaman bagi ekosistem lamun. Perlu adanya restorasi lamun agar lamun tdak terus berkurang. Data lamun dan gastropoda diperlukan untuk menunjang kegiatan restorasi. Tujuan dari penelitian ini adalah untuk mengetahui kondisi dan hubungan lamun terhadap gastropoda serta strategi restorasi lamun. Pengambilan data lamun dan gastropoda berdasarkan prosedur tetap taman nasional menggunakan transek kuadrat 1x1m pada 3 area yang mewakili Pulau Pramuka Terdapat 5 spesies lamun. Tutupan lamun di Pulau Pramuka 10.64 – 17.07%, (kategori miskin). Terdapat 21 spesies gastropoda. Kepadatan gastropoda tertinggi spesies Rhinoclavis sp. B. Indeks biodiversitas gastropoda di Pulau Pramuka menunjukan kategori komunitas sedang. Nilai keseragaman gastropoda termasuk dalam kategori komunitas yang kondisinya stabil. Hubungan antara kerapatan lamun dan kepadatan gastropoda menunjukkan korelasi kuat (0.865). Berdasarkan data tersebut dapat dirumuskan strategi restorasi untuk meningkatkan kualitas manajemen konservasi meliputi membenahi pengelolaan lamun dengan mengajak masyarakat, instansi dan akademisi. Melakukan monitoring, tranplantasi, dan sosialisasi tentang lamun. Mengalokasian dana untuk kegiatan yang berhubungan dengan lamun oleh pemerintah dan swasta.
English Abstract
Seagrass has several important functions in coastal areas. Many organisms including gastropod depend on the existence of seagrass. Anthropic activities in Pramuka Island produce a lot of waste and become threat to the seagrass habitat. Therefore, it is necessary monitoring program to prevent seagrass degradation. The purposes of this research is to know the seagrass cover and the relation between seagrass and gastropod as well as to formulate the strategy for seagrass restoration. The method reffering fixed procedure of collecting biological resource data by Kepulauan Seribu National Park of using 1x1m quadratic transects. Whereas, seagrass with gastropod abundance collected from the 3 representative areas of Pramuka Island. The result of this study shows that there were 5 species of seagrasses. Coverage percentage in Pramuka Island range from 10.64 - 17.07% (categorized as poor). There are 21 species of gastropods. Highest gastropod density was Rhinoclavis sp. B (North: 1.47 ind/m2; East: 0.6 ind/m2; South: 0.73 ind/m2). Index of biodiversity of gastropod show the stable condition. There was no dominant gastropod recorded in Pramuka Island. The relationship between seagrass and gastropod density indicated a strong correlation (0.865). Seagrass density could affect the density of gastropods by 74.9%. From the article above some seagrass restoration strategies are formulated to improve the quality of conservation management includes to improve the management of seagrass by involving local community. The government and the private sector need to allocate funds seagrass restoration.
