Abstract

This study aims to determine the structure of the mangrove community on the coast of Peunaga Rayeuk, Meurebo District, and West Aceh District. The method used in this study was line transect, making transects/plots for each observation station with a size of 10x10 m2 with 3 replications so that each observation station has an area of ​​30x10 m2. This research was conducted in October 2022. There were 2 types of mangroves included in the observation station, namely Rhizophora apiculata and Avicennia alba, while the associated mangrove was of the type Acrostichum speciosum. In addition, there are also associated mangroves that are not included in the observation station but are located around the observation station, namely Nypa fruticans, Hibiscus tiliaceus, and Pandanus odoratissima. Stations 1 and 2 were dominated by sandy and muddy sand substrates, which respectively showed a diversity index of 0.054 and 0.149, a uniformity index of 0.078 and 0.215, and a dominance of 0.478 and 0.252. The most abundant species was R.apiculata with a relative density of 0.949 ind/ha, followed by S.alba of 0.051. Relative cover of R.apiculata and S.alba respectively with the range of 0.302 and 0.698. The results of this study concluded that over all the structure of the mangrove community on the coast of Peunaga Rayeuk is still classified as low, so it requires greater attention in the restoration and management of mangrove ecosystems

Abstract

Marine debris has become an increasing environmental threat in the world. West Aceh's coast is designated for tourism and fishing activities. This study determines the composition, characteristics, and abundance of waste on two selected beaches with economic activities for fishing (daily activities of coastal communities) and tourism activities. Garbage collection was carried out on two beaches on the coast of Johan Pahlawan District, West Aceh Regency, namely Pasar Baro Beach and Ujung Karang Beach. Pasar Baro Beach and Ujung Karang Beach were chosen because they are near fish market activities and recreational beaches, respectively. Determination of the sampling area by distance, from the low tide line to the first vegetation or concrete on the beach. The sampling length was measured using a 100 m roll meter parallel to the coastline. The results showed that the total weight (%) and frequency of waste per category were highest in the household category at Pasar Baro Beach. While at Ujung Karang Beach, the highest frequency of garbage is found in the variety of plastic drink bottles. The difference in abundance at the two stations is due to differences in visits and activities of the surrounding community. In addition, due to the lack of local cleaning efforts and facilities that could be more optimal, piles of garbage are still found along the coast
