Abstract

ABSTRAK Ekosistem hutan mangrove di Indonesia memiliki fungsi ekonomis dan ekologis. Salah satu dari potensi ekonomis mangrove R. apiculata merupakan bahan alami yang berfungsi sebagai bioaktif yang digunakan dalam pengobatan bagi manusia maupun hewan. Masyarakat pesisir juga menggunakan daun mangrove sebagai bahan pembuatan produk minuman berkhasiat. Selanjutnya potensi ekologis yaitu menjadi penahan ombak laut dan sebagai habitat biota. Namun, kandungan senyawa daun mangrove yang dikumpulkan dari sekitaran Pantai Lhok Bubon dapat mempengaruhi kelangsungan hidup ikan dan memiliki pengaruh langsung dengan perubahan parameter kualitas perairan. Dampak perendaman daun mangrove ini beresiko mengganggu aktivitas fisiologis ikan kemudian jika perairan mengalami perubahan faktor fisika dan kimia perairan dapat menghasilkan toksik bagi berbagai biota. Tujuan penelitian ini adalah untuk mengetahui nilai LC50-96 jam selama perendaman daun R. apiculata yang berdampak toksik terhadap biota uji. Biota uji yang digunakan adalah ikan molly (Poecilia sp.) yang biasanya digunakan untuk indikator perubahan lingkungan. Penelitian ini dilakukan dengan penentuan konsentrasi antara lain 10, 20, 30, 40, 50% kemudian dianalisis melalui metode analisis probit. Hasil penelitian memiliki nilai LC50-96 jam yang diperoleh dari hasil komposit seluruh perlakuan konsentrasi dari perendaman daun R. apiculata sebesar 559.16 ppm yang artinya termasuk kategori toksik rendah. Meskipun demikian, persentase tingkat toksisitas menunjukkan sebesar 6% sehingga dapat menyebabkan kematian ikan. Kata kunci: LC50-96 jam, toksisitas, mortalitas ikan ABSTRACT  Mangrove forest ecosystems in Indonesia have economic and ecological functions. One of the economic potentials of R. apiculata mangrove is a natural ingredient that functions as a bioactive used in medicine for humans and animals. Coastal communities also use mangrove leaves as ingredients for making nutritious beverage products. Furthermore, the ecological potential is as a barrier to sea waves and as a habitat for biota. However, the content of compounds in mangrove leaves collected from Lhok Bubon coast that can affect the survival of fish directly influences changes in water quality parameters. The impact of soaking mangrove leaves is at risk of disrupting the physiological activity of fish, then if the waters experience changes in physical and chemical factors, it can produce toxins for various biota. This study aimed to determine the LC50-96 hour value during immersing R. apiculata leaves which have a toxic impact on the test biota. The test biota used was mollyfish (Poecilia sp.) which is usually used as an indicator of environmental change. This study was conducted by determining concentrations including 10, 20, 30, 40, 50% then analyzed using the probit analysis method. The results showed an LC50-96 hour value obtained from the composite results of all concentration treatments from soaking R. apiculata leaves of 559.16 ppm, which means it is included in the low toxic category. However, the percentage of toxicity level showed 6% so that it could induce fish mortality. Keywords:  LC50-96 hour, toxicity, fish mortality

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 community service initiative aims to enhance awareness and encourage active participation among the residents of Peunaga Cut Ujong Village, Meureubo Subdistrict, West Aceh Regency, in environmental conservation efforts through mangrove planting. Located in a coastal area vulnerable to erosion and exposed to air pollution due to coal-burning activities, this village faces significant environmental challenges. Employing an educational and participatory approach, the program involved raising awareness about the ecological functions of mangroves and conducting direct planting activities in a mangrove forest area approximately 100 meters from the shoreline. The outcomes of the initiative indicated a positive response from the community, demonstrated by increased environmental awareness and active involvement in conservation efforts. Mangrove planting is expected to function as a coastal protection barrier, an air pollutant absorber, and a potential site for ecotourism and aquaculture development. This initiative highlights the importance of synergy between academia, the local community, and the industrial sector in creating sustainable environmental solutions. Continuous evaluation and the replication of similar programs are strongly recommended to enhance their long-term impact.

Abstract

Seagrass beds are one of the coastal ecosystems that have an important role in maintaining the balance of the marine environment. Indonesia is known for its rich seagrass species but not much has been reported, especially in Aceh waters.This study aims to identify and analyse the distribution and condition of seagrass health through the percentage cover and dominance of seagrass species in Pulau Banyak District, Aceh Singkil Regency. Seagrass research was conducted in July 2024 at 3 different stations, namely Nago, Matahari and Panjang Islands. The research method used was the method of drawing a 100 m long line transect, with each station being repeated 3 times at 50 m, so that the seagrass area observed was 100 m2. Differences in the condition of the aquatic environment showed differences in the presence of seagrass species found. A total of 4 seagrass species were recorded in this study, namely Thalassia hemprichii, Enhalus acoroides, Cymodocea rotundata and Halophila ovalis. There is a difference in the number of seagrass species found in the 2015 and 2023 time periods, the 2024 survey recorded 4 species from the previous 5 seagrass species. The highest percentage of seagrass cover was found on Nago, Matahari and Panjang Islands with percentages of 19.98%, 3.69% and 1.23% respectively. The highest overall seagrass species cover was T. hemprichii at 60.268%, while the lowest seagrass species was H. ovalis at 3.534%. Based on the results of the analysis of the percentage of seagrass cover of the entire research station, it is concluded that seagrass in the waters of Pulau Banyak is included in the category of sparse cover, with poor condition status (≤29.9).
