Community structure of mangrove in Lambadeuk village, Aceh Besar regency, Indonesia

Abstract

Mangroves are plants that can live in tidal areas. The study aims to determine the condition of the mangrove ecosystem through a mangrove community structure approach in Lambadeuk Village, Peukan Bada District, Aceh Besar District. This research was conducted in November 2017 using the stratified sampling method. The results showed that there were only 2 types of mangrove species found in Lambadeuk Village, Peukan Bada District, Aceh Besar District, the first is Rhizophora apiculata as many as 36 individuals and the second one is Rhizophora mucronata as many as 116 individuals. The important value index (INP) tree and sapling of Rhizophora apiculata at station 1 and station 3 of 253.655% and station 2 of 183.789%. While seedling of Rhizophora apiculata at station 1 and station 3 of 250.04% and station 2 of 175.02%. The important value index (INP) tree and sapling of Rhizophora mucronata at station 1 and station 3 of 253.655%. While seedling of Rhizophora mucronata at station 1 and station 3 of 250.04%. The diversity (H') obtained is low where H' 2.0, dominance (C) is low where 0 < C 0.5 and evenness (E) is also low where 0 < E 0.5.

Relationship of mangrove snail’s abundance (Cerithidea sp.) with mangrove density at mangrove ecosystem in Banda Aceh and Aceh Besar

“…Some related study about biotic mangrove ecosystem especially gastropod done by [16] about community structure of gastropods and bivalves associates in mangrove area at Pusung Cium Island, Aceh Tamiang, [17] about distribution pattern of gastropods in mangrove ecosystem at Reuleung River, Aceh Besar. Furthermore [18] found Cerithidea cingulata was the highest gastropods abundance in mangrove rehabilitation Aceh Besar and Banda Aceh. However, the pattern distribution of Cerithidea sp.…”

Literatur Review: Pencemaran Logam Berat di Pelabuhan Indonesia

“…Logam berat timbal (Pb) merupakan jenis logam berat yang paling dominan diteliti yaitu di 38 pelabuhan Indonesia (Gambar 3, Tabel 1). Pentingnya penelitian logam berat dapat dijadikan sebagai acuan terhadap pencegahan kerusakan yang ditimbulkan oleh logam berat yang bersifat karsenogenik baik bagi lingkungan seperti biota perairan: terumbu karang (Najmi et al, 2023), ikan karang (Fazillah et al, 2020), ikan bioindikator perairan (Octavina et al, 2021) dan makrozobenthos (Razi et al, 2021); ekosistem sekitar seperti mangrove (Octavina et al, 2022) dan lamun (Fazillah et al, 2021); dan juga dapat berdampak pada manusia dimana mengonsumsi ikan yang di daratkan di pelabuhan perikanan (Razi et al, 2022). Memperdalam informasi terkait logam berat dapat memberikan solusi alternatif mengatasi pencemaran lingkungan dari sumber daya alam baik dari tumbuhan, alga hingga bakteri serta memberikan peluang bagi teknologi dalam pengembangan dan meningkatkan efesiensi dalam perawatan lingkungan bagi masyarakat.…”
