Abstract

Perairan Aceh bagian Barat terletak di bagian Timur Samudera Indonesia. Kawasan ini merupakan perairan yang dinamis karena merupakan bagian dari perairan Indonesia yang terletak di antara dua benua dan dua samudera. Konsentrasi klorofil-a bervariasi secara bulanan di perairan ini. Penelitian ini mengamati variasi konsentrasi klorofil-a berdasarkan sirkulasi angin muson. Analisis konsentrasi klorofil-a dapat digunakan untuk membantu perkiraan produktivitas sebuah perairan. Kami menemukan bahwa konsentrasi klorofil-a di Monsun Barat lebih tinggi daripada di Monsun Timur. Sebaliknya, konsentrasi klorofil-a di Monsun Timur lebih rendah dibandingkan di Monsun Barat.

Abstract

Environmental factors and geographical variations in an ecosystem are important steps in explaining the dynamics of marine communities, a study of seaweed that grows naturally on the west coast of Simeulue Island was conducted with the purpose of learning about the environmental characteristics, geographical variations, and environmental parameters that affect their distribution. The study was conducted in October 2021, and it included 5 observation stations with environmental factors measured in situ and geographic variation data using line transects along 50 m perpendicular to the shoreline and sample plots measuring 1 x 1 m every 10 m. Environmental factors that influence vegetation conditions and geographic variations of seaweed were analyzed using PCA. The study's findings revealed that conditions in the Indian Ocean with a high pH (average 07.72 ± 00.20) with moderate salinity and current velocity (average 32.47‰± 01.72 and 00.32 m/s ± 00.11, respectively) influenced the seaweed vegetation habitat. Then 21 seaweed species were identified, all of which have not been evaluated on the IUCN Red List, and their distribution is relatively rare, with a frequency of only 20%, and the seaweed zoning found at a depth of 0 - 150 cm at the lowest tide and a distance of up to 40 m inland from the edge. Furthermore, the distribution of seaweed on Simeulue Island's west coast is largely determined by DO conditions, salinity, and current velocity, whereas pH and temperature have less influence on seaweed distribution.  Faktor lingkungan dan variasi geografik di suatu ekosistem merupakan langkah penting dalam menjelaskan dinamika komunitas laut, sehingga kajian rumput laut yang tumbuh alami di Pantai Barat Pulau Simeulue dilakukan dengan tujuan untuk mengetahui karakteristik lingkungan, variasi geografik dan parameter lingkungan yang mempengaruhi distribusinya. Kajian dilaksanakan pada bulan Oktober 2021 yang terdiri dari 5 stasiun pengamatan dengan faktor lingkungannya diukur secara in situ dan data variasi geografiknya menggunakan transek garis sepanjang 50 m tegak lurus garis pantai serta dibuat petak contoh berukuran 1 x 1 m disetiap 10 m dan faktor lingkungan yang mempengaruhi kondisi vegetasi maupun variasi geografik rumput lautnya dianalisis menggunakan PCA. Hasil kajian memperlihatkan bahwa habitat vegetasi rumput lautnya dipengaruhi oleh kondisi Samudera Hindia dengan konsentrasi pH perairannya tergolong tinggi (rata-rata 07.72 ± 00.20) dan konsentrasi salinitas maupun kecepatan arusnya tergolong sedang (rata-rata 32.47‰ ± 01.72 dan rata-rata 00.32 m/s ± 00.11), kemudian rumput lautnya teridentifikasi sebanyak 21 spesies yang keseluruhannya belum terevaluasi di IUCN Red List dan distribusinya tergolong jarang dengan frekuensi relatifnya kecil dari 20% serta zonasi rumput lautnya ditemukan pada kedalaman ± 0 – 150 cm saat surut terendah dan berjarak hingga ± 40 m ke arah daratan dari tubir. Selanjutnya, untuk distribusi rumput laut di pantai Barat Pulau Simeulue sangat ditentukan oleh kondisi DO, salinitas dan kecepatan arus, sedangkan parameter pH dan suhu kurang memberikan pengaruh yang baik terhadap distribusi rumput lautnya.

Abstract

The growth of an organism can provide fundamental ecological data and serve as a primary parameter for describing an organism's population dynamics. Telescopium telescopium gastropods were studied in September 2021 using purposive sampling in the mangrove forest of Cut Mamplam Village, Aceh Province. This study aims to provide fundamental data for mangrove management in Indonesia. Data were collected by creating a 40 m perpendicular to the coastline line transect, followed by 10 x 10 m sample plots and five 1 x 1 m sub plots. Following the collection of samples, additional analysis of the density, length and weight relationship, demographic structure, spatial distribution patterns based on the Morisita index, and growth characteristics were conducted as unique characteristics when compared to T. telescopium in other areas analyzed using PCA. The study's findings indicated that the density was low (< 7 ind/m2), the allometric length and weight relationship was negative (b < 3), the dominant growth demographic structure was mature (dominant SL 79.36 – 86.34 mm), the distribution pattern was clustered (Iδ = 02.75), and the BT, BWL, and AL morphometrics, in particular, had a variance of 95.91%. Pertumbuhan suatu organisme dapat menyediakan data ekologi dasar dan merupakan salah satu parameter yang utama dalam mengambarkan dinamika populasi suatu organisme, sehingga kajian gastropoda Telescopium telescopium di hutan mangrove Desa Cut Mamplam Provinsi Aceh dilakukan menggunakan purposive sampling pada bulan September 2021 dengan tujuan sebagai data dasar dalam pengelolaan mangrove di Indonesia, dimana data dikumpulkan dengan cara membuat transek garis sepanjang 40 m tegak lurus garis pantai, kemudian dibuat petak-petak contoh berukuran 10 x 10 m dan selanjutnya dibuat sub plot berukuran 1 x 1 m sebanyak 5 sub plot. Setelah sampel terkumpul, selanjutnya dilakukan analisis kepadatan, hubungan panjang berat tubuh, struktur demografi, pola penyebaran spasial berdasarkan indeks Morisita dan karakteristik pertumbuhannya sebagai penciri khusus bila dibandingkan dengan T. telescopium di kawasan lain yang dianalisis menggunakan PCA. Hasil kajian memperlihatkan bahwa kepadatannya rendah (< 7 ind/m2), hubungan panjang beratnya allometrik negatif (b < 3), struktur demografi pertumbuhan yang dominan ditemukan tergolong dewasa (SL dominan 79.36 – 86.34 mm), pola penyebarannya mengelompok (Iδ = 02.75) dan morfometrik BT, BWL maupun AL sebagai penciri khususnya memiliki varian 95.91%.

Abstract

Shellfish (bivalves) are potential biodiversity of waters with an important significant value used by the community as a food source of highly nutritious animal protein. Based on survey results, several coastal areas in North Aceh District have the potential for shellfish. Still, there have not been any scientific reports on this region's proximate composition of bivalves. This study aims to determine the relative arrangement of the dominant bivalves in the North Aceh District based on species differences and environmental characteristics. The results showed varying proximate bivalve proximate compositions of 4 chief types of shellfish in North Aceh waters. Bivalvia water ranged from 6.9-14.2%, ash ranged from 5.87-8.29%, protein ranged from 32.84-35.87%, fat ranged from 3.04-10.83%, and carbohydrate ranged from 38.11-42.71%. The highest protein and fat content were found in the Crassostrea sp1 type clams. In addition, the differences in the environmental characteristics of the shell sampling locations also resulted in different proximate compositions. The PCA test results showed that the critical variablarrangemente composition was ash and fat content. The environmental parameters, which were the key parameters of the relative arrangement of the shells were the substrate and pH.

Abstract

The aim of this service activity was to socialize and train fishermen's wives in Cot Seurani Village, Muara Batu Sub-District, North Aceh District how to process fish. The target of the training was that fishermen's wives understand and are creative in producing fish products as healthy alternative snacks for children during their growth and development stages. This activity had several stages which were program planning, preparation, training to process fish into fish nuggets and dragon feet products. From the program planning stage, the survey showed that: 1) the fishermen's wives did not have sufficient skills to process fish; 2) during the catching season, fish is usually sold at a low price; and 3) the children of the fishermen did not like to eat fish and preferred chicken and other street foods. The result of this service activity was that the participants have already had the skills and practiced directly how to make fish nuggets and dragon feets. In conclusion, the fishermen's wives can now provide fish products for their children.
