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

Abstract

This research aims to evaluate the effectiveness of waste prevention efforts that have been carried out by the community in Johan Pahlawan District and Bubon District. Through qualitative and quantitative research methods, data was collected from field surveys, interviews, and statistical analysis regarding waste management practices, community participation, and levels of environmental awareness. The results of the research show that the community in both sub-districts has implemented waste prevention efforts well. An increase in environmental awareness among the community can be seen from active participation in waste management activities, waste separation, and the use of environmentally friendly products. Implementation of policies by local governments also makes a positive contribution in creating a cleaner and more sustainable environment.This research provides a comprehensive picture of waste prevention practices that have been successfully implemented by the community in Johan Pahlawan and Bubon Districts. It is hoped that these findings will provide insight for the government and related institutions to increase the sustainability of waste prevention efforts at the local level and stimulate similar practices in other areas.

Abstract

Penelitian ini bertujuan untuk menginventarisasi dan mengidentifikasi karakteristik makroalga yang terdapat di substrat berbatu Pulau Reusam, Aceh Jaya. Survey ini dilakukan menggunakan metode ekplorasi pada tiga stasiun pengamatan, dengan pencatatan visual dan pengambilan sampel makroalga. Masing-masing stasiun diamati sepanjang 50 m sehingga seluruh stasiun pengamatan sepanjang 150 m. Identifikasi dilakukan berdasarkan morfologi makroalga yang mencakup bentuk, warna, dan struktur talus. Hasil penelitian menunjukkan bahwa pulau Reusam memiliki keanekaragaman makroalga yang terdiri dari dua divisi utama, yaitu Chlorophyta (alga hijau) dan Phaeophyta (alga cokelat). Spesies yang ditemukan meliputi Dictyota dichotoma, Sargassum aquifolium, Iyengaria stellata, Hincksia mitchelliae, Chaetomorpha indica dan C. crassa. Gangguan lingkungan seperti substrat berbatu, paparan sinar matahari langsung dan hantaman gelombang kemungkinan menjadi faktor penentu jenis alga pada lokasi ini. Data ini menjadi studi pendahuluan yang dapat digunakan untuk Upaya konservasi dan pengelolaan dalam melindungi keanekaragaman makroalga di Pulau Reusam, Aceh Jaya. Selain itu, juga dapat menjadi data dasar yang penting untuk pengembangan potensi sumber daya laut di wilayah tersebut.

Abstract

AbstrakGastropoda menjadi salah satu sumberdaya hayati non ikan yang mempunyai keanekaragaman tinggi. Gastropoda juga berperan penting dalam fungsi ekologi dan siklus rantai makanan pada ekosistem mangrove. Mangrove merupakan salah satu sumber makanan gastropoda yang dapat membantu pertumbuhannya sehingga dapat meningkatkan keanekaragaman gastropoda di sekitar kawasan mangrove. Namun, adanya aktivitas penebangan pohon mangrove menjadi lahan pemukiman dan kebun sawit dapat mempengaruhi kondisi lingkungan tempat hidup gastropoda. Penelitian bertujuan mengetahui informasi tentang jenis-jenis gastropoda di kawasan mangrove  Kecamatan Kuala Batee Kabupaten Aceh Barat Daya. Penentuan stasiun penelitian menggunakan teknik purposive sampling. Gastropoda yang ditemukan di kawasan mangrove  Kecamatan Kuala Batee Kabupaten Aceh Barat Daya sebanyak 11 spesies dari 4 ordo yaitu Archaeogastropoda antara lain Neritina turita, Neritina semiconica, Neritina variegate, Neritodryas dubia, dan Clithon corona, dari ordo Ceanogastropoda Faunus ater dan Bitium munitum, dari ordo Mesogastropoda yaitu Cerithidea optusa, Stenomelania plicaria, dan Thiara scabra,  dari ordo Ellobiida yaitu Cassidula angulifera.  Kata kunci : Aceh Barat Daya, Gastropoda, Mangrove
