Analisis Kerapatan Ekosistem Mangrove Di Pulau Panikiang Dan Desa Tongke-Tongke Sulawesi Selatan

Abstract

The mangrove ecosystem has different density levels per location. It can be influenced by environmental factors or because of human assistance. This research was conducted in Tongke-tongke Village, Sinjai Regency and Pannikiang Island, Barru District. Observations were conducted on three groups, namely groups of trees, stakes, and seedlings. Tree group used plot size 10 m x 10 m, stakes group used plot size 5m x 5m, and the group of seedlings used plot size 1 m x 1m. The result of tree group density will be compared with the standard criteria of mangrove damage of the Minister of Environment to know the criteria and the level of density. The mangrove ecosystem in Tongke-tongke village is overgrown by Rhizophora mucronata and Avicennia sp. and is dominated by R. mucronata with very dense density. In the tree group, R. mucronata has a density of 8020 Ind Ha-1. The mangrove ecosystem in Pannikiang Island is overgrown with Rhizophora apiculata, Rhizophora stylosa, Sonneratia alba, Aegiceras floridum, Ceriops tagal, Avicennia sp., Excoearia agallocha, and Lumnitzera racemosa and has a rare and moderate density. In the tree group, the highest density in C. tagal with a density of 1270 Ind Ha-1 and indicated moderate density. Competition is always there in the ecosystem. The species of this ecosystem is fighting for space and nutrients. Therefore, competition can determine the density of plants in it.

Phylogenetic Relationships of Isognomon (Lightfoot, 1786) Oysters from North Sulawesi, Indonesia

“…According to the review by Benthotage et al (2020), species in the genus Isognomon are widely distributed in various regions around the world, from North America to Asia and Oceania. In Indonesia, species of this genus are found in many islands, including Maluku (Silulu et al, 2013), Belitung (Cappenberg and Wulandari, 2019), Sulawesi (Rau et al, 2013;Samsi et al, 2019), Lombok (Putra et al, 2021), Papua (Marey and Maitindom, 2019), Aceh (Mutia et al, 2021), Riau (Simarmata and Fajri, 2020), Sumatera (Rinaldi, 2021), and other islands.…”

Sosialisasi Mengenai Biodiversitas Dan Faktor Lingkungannya

“…Penelitian mengenai ekosistem mangrove bisa dilakukan secara langsung ke lokasi dan juga bisa dengan menggunakan citra satelit (Nguyen, Nguyen, Le, & Tran, 2019). Berbagai penelitian yang bisa dilakukan di ekosistem mangrove jika dilakukan secara langsung, baik mengenai mangovenya sendiri (Samsi, 2017), plankton (Rusmidin, Andy Omar, & Nessa, 2019), kerang-kerangan (Samsi, Andy Omar, Niartiningsih, Soekendarsi, & Rusmidin, 2019), dan siput bakau (Samsi, Andy Omar, Niartiningsih, & Soekendarsi, 2020.…”

“…Faktor lingkungan akan membatasi tumbuh dan kembang makhluk hidup sehingga terkadang hanya jenis-jenis tertentu yang dapat hidup pada ekosistem tertentu. Salah satu contohnya yaitu Rhizophora hanya dapat hidup di ekosistem mangrove (Noprianti, Samsi, & Liana, 2018;Samsi, Andy Omar, & Niartiningsih, 2018b).

Identifikasi Tumbuhan Mangrove Dan Pemanfaatannya Di Pulau Aru Provinsi Maluku

“…Nypa fruticans (Arecaceae) Ngomar Daun: bisa menggantikan kertas rokok N. fruticans juga ditemukan di Kupang [10], di Desa Sei Nagalawang Kabupaten Serdang [11], di Daun Kecamatan Sangkapura dan Desa Sukaoneng Kecamatan Tambak Pulau Bawean Kabupaten Gresik [12]. Daun N. fruticans di Desa Kalar-Kalar dimanfaatkan oleh masyarakat sebagai pengganti kertas rokok.…”
