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.
Highlights
The mangrove ecosystem is a vegetation in the tropics invalue as a unique ecosystem, which can live in water with high salinity, and are usually found along the tidal areas [7]
Based on observations at the research site, there are 2 types of mangroves located in Lambadeuk village, Peukan Bada sub-district, Aceh Besar district, namely of species Rhizophora apiculata and Rhizophora mucronata
The number of each tree category, saplings and seedlings found at Station 1 is 61 individuals at station 2 there is only one type of mangrove, from Rhizophora Apiculata
Summary
The mangrove ecosystem is a vegetation in the tropics invalue as a unique ecosystem, which can live in water with high salinity, and are usually found along the tidal areas [7]. Mangrove forests are the main ecosystem that supports life in coastal and marine areas. Aceh Besar District is an area located at the northern tip of Aceh Province with a coastline of 344 km which is rich in biodiversity [5], one of which is mangroves. The potential of mangrove resources can be founded in Lambadeuk Village, Peukan Bada District, Aceh Besar Regency. Most of the mangrove area in the village have been damaged due to the impact and Tsunami disaster in 2004, so that rehabilitation efforts are managed by the government. The research reporting on the condition of mangroves in Lambadeuk Village, Peukan Bada District is still limited. This study aims to determine the condition of the ecosystem mangrove through a community structure approach in Lambadeuk Village, Peukan Bada District, Aceh Besar District
