Biodiversitas Mangrove di Pulau Mansuar Kabupaten Raja Ampat Provinsi Papua Barat (The Biodiversity of Mangrove in the Mansuar Island Raja Ampat District West Papua Province)

Abstract

AbstrakHutan mangrove merupakan formasi hutan yang tumbuh dan berkembang pada daerah landai di muara sungai dan pesisir pantai yang dipengaruhi oleh pasang surut air laut dan pantai berlumpur. Penelitian ini bertujuan untuk menganalisis biodiversitas mangrove di Pulau Mansuar Kabupaten Raja Ampat, Provinsi Papua Barat. Metode yang digunakan yaitu transek kuadrat. Hasil penelitian ditemukan sebanyak 6 famili 11 spesies dan 554 individu mangrove. Komposisi individu tertinggi dimiliki oleh spesies Rhizophora apiculata, sedangkan terendah yaitu spesies Xylocarpus rumpii. Indeks keanekaragaman, kekayaan, dan kelimpahan spesies mangrove pada semua tingkat pertumbuhan tertinggi pada stasiun 3, sedangkan terendah pada stasiun 1. Berdasarkan besaran kriteria yang dikemukakan oleh Shannon-Weiner maka indeks keanekaragaman mangrove di Pantai Yenbubua, Kepulauan Mansuar tergolong kategori sedang. Kata kunci: biodiversitas, kekayaan spesies, Pulau Mansuar, Rhizophora apiculata. AbstractMangrove forests are forest formations that grow and flourish in slopes at the mouth of the rivers and coastal areas that are affected by tidal sea water and muddy beaches. This study aimed to analyze the biodiversity of mangroves in Mansuar Island, Raja Ampat District, West Papua Province. The method used was quadrat transects. The results of the study showed that there were 6 families of 11 species and 554 individuals. The highest composition of the individual mangrove species was Rhizophora apiculata, while the lowest composition was Xylocarpus rumpii. The highest diversity index, richness, and abudance spesies in a various growth rate were observed in the station 3, while these lowest parameters were found in the station 1. Based on the magnitude of the criteria proposed by Shannon-Weiner, the index of mangrove diversity in Yenbubua Beach, Mansuar Islands was classified as medium category.

Nilai biodiversitas lanskap mangrove DKI Jakarta, Kelurahan Penjaringan, Kecamatan Muara Kamal, Jakarta Utara

“…Lanskap mangrove dikenal sebagai vegetasi yang mampu hidup di zona transisi antara daratan dan lautan. Hal tersebut menjadikan ekosistem mangrove memiliki tingkat keanekaragaman yang tinggi, baik flora maupun fauna (Sengupta 2010;Mayor et al 2017). Vegetasi mangrove tumbuh di sepanjang garis pantai hingga ke muara sungai dan dipengaruhi oleh pasang surut air laut (Baderan 2016).…”

Discovery of habitat preferences and community structure of Echinoderms in Kri, Raja Ampat, Indonesia

“…The abundance of biodiversity is linked to the various ecological supports provided by coral reef vegetation, seagrass beds, and mangrove forests. Various habitats provide optimum support for the development and survival of various organisms (Mayor et al 2017). According to Tapilatu et al (2021), the complexity of a coastal ecosystem can support a wide range of living organisms, including elasmobranchs, reptiles, marine mammals, and various types of invertebrates.…”

“…This field has yielded several study discoveries (Tafalas 2010;Mayor et al 2017;Subhan et al 2020). However, more is needed to know about the organism habitat preferences or community structure of echinoderms in this location.…”
