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

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

Penggunaan bahan bakar fosil yang terus berlangsung akan meningkatkan konsentrasi karbondioksida (CO2) di atmosfer. Asidifikasi laut terjadi akibat CO2 yang berada di atmosfer berdifusi ke lautan. Lautan mampu menyerap CO2 di atmosfer sebanyak 35 % lebih yang menyebabkan terjadinya penurunan pH laut. Lamun Cymodocea rotundata merupakan salah satu jenis lamun yang banyak ditemukan tumbuh di perairan tropis. Keadaan ini menimbulkan kekhawatiran tentang kemungkinan terjadinya dampak pada pertumbuhan lamun C. rotundata. Penelitian ini bertujuan untuk menganalisis kandungan nitrat, fosfat dan kalium dan pertumbuhan lamun C. rotundata yang meliputi pertumbuhan daun, rhizoma, dan akar C. rotundata terhadap perbedaan pH. Penelitian menggunakan metode eksperimen dengan rancangan acak lengkap menggunakan tabel acak. Sebanycak 15 toples dengan ukuran diameter 20 cm dan tinggi 25 cm digunakan dengan 3 perlakuan, masing-masing perlakuan 5 kali pengulangan. Hasil uji regresi linier menunjukkan pH berpengaruh terhadap konsentrasi nitrat, dan berpengaruh kuat terhadap konsentrasi fosfat dan kalium. Laju pertumbuhan daun lamun C. rotundata tertinggi pada kontrol berkisar antara 0,50–1,29 mm/hari sedangkan yang terendah pada pH rendah berikisar 0,07–0,73 mm/hari. Laju pertumbuhan rizhoma lamun secara horizontal dan vertikal tertinggi pada pH rendah sedangkan yang terendah pada pH kontrol. Laju pertumbuhan akar lamun tertinggi pada pH rendah berkisar antara 0,20–0,90 mm/hari. sedangkan yang terendah pada kontrol berkisar antara 0,13–0,43 mm/hari. pH juga memengaruhi laju pertumbuhan daun, rhizoma dan akar lamun C. rotundata. Semakin rendah pH maka laju pertumbuhan daun juga semakin rendah, berbeda dengan rhizoma dan akar semakin rendah pH maka semakin tinggi laju pertumbuhan.

Abstract

One of the best potential mangrove forests is located in Lhokseumawe City. Mangrove forests function as protected areas in coastal areas and are used as vegetation whose existence must be maintained. Efforts to protect it can be carried out by mapping the distribution of mangrove forest areas as a database in Lhokseumawe City. Mapping the distribution of mangrove forest areas can be done using remote sensing. This research was conducted in October - November 2022 in Lhokseumawe City. The method used in this study is the visual interpretation of remote sensing imagery and field surveys. Visual interpretation techniques are used to find out the extent of information from satellite imagery in 2022 which has been geometrically corrected regarding mangrove forest vegetation. Field surveys are needed to obtain more accurate data results. The results of research on mangrove vegetation in Lhokseumawe City are found in 4 sub-districts, namely: Muara Satu District, Banda Sakti District, Muara Dua District, and Blang Mangat District with a total area of ± 65.74 Ha. The results of the density level of mangroves in Lhokseumawe City are dominantly rare with a value of 0.32 m2

Abstract

Marine debris consists of materials discarded or unintentionally introduced into the marine environment by human activities. The increasing volume of marine debris is largely attributed to human activity near coastal areas. Bluka Teubai Beach, North Aceh, a popular visitor destination, has a high potential for waste accumulation. This study, conducted in May 2024, employed a purposive sampling method to assess marine debris. The research area was divided into three stations with distinct characteristics, using the line transect method. Results from Bluka Teubai Beach identified two primary waste categories: organic and inorganic. Organic waste included wood, bamboo, and coconut husk, while inorganic waste consisted of plastic, glass, metal, and rubber. Among organic waste, wood exhibited the highest absolute density (0.456 items/m²) and relative density (53.950%), followed by bamboo (0.317 items/m², 39.641%) and coconut husk (0.049 items/m², 6.409%). The overall density of organic waste at Bluka Teubai Beach was highest for wood (0.23 items/m²), with an average relative density of 58.640%. For inorganic waste, plastic had the highest absolute density in pieces (2.24 items/m²) and relative density in pieces (96.968%). The highest absolute density and relative mass of inorganic waste were also found in plastic (99.94 g/m² and 64.36%, respectively). Temporal analysis revealed that organic waste accumulation peaked on Fridays, while inorganic waste was most abundant on Tuesdays in terms of count and on Sundays in terms of mass. The results underscore the urgent need for targeted waste management strategies and continuous monitoring to mitigate marine debris pollution and protect the coastal ecosystem of Bluka Teubai Beach.

Abstract

<p>Seaweed is an important biological resource for human life, serving essential ecological functions, including providing shelter and feeding grounds for marine biota. Seaweed can be found in several Indonesian waters, growing naturally or through cultivation, including in the waters around Simeulue Island. This study aimed to assess the distribution of seaweed in relation to land suitability, using oceanographic parameters in Simeulue Island waters. The research was conducted at five stations within the West Teupah District, South Teupah District, and Alafan District. In situ measurements were taken to evaluate land suitability for seaweed growth based on oceanographic parameters such as current speed, depth, substrate type, salinity, temperature, pH, and dissolved oxygen. Results indicated that seaweed in Simeulue Island waters is distributed along the coastline and attached to coral reefs and rocks at depths of 2-5 meters. The total area of seaweed distribution is approximately 351.83 hectares along a coastline of 206.12 km. The measured parameters of seaweed habitats include a pH of 7.7 to 7.9, salinity of 31-35.3 ppt, temperature of 20-30 °C, dissolved oxygen levels of 3-4.8 mg/L, depth of 2-5 meters, current speed of 0.10 to 0.60 m/s, and a sandy coral substrate. Based on these water quality and substrate parameters, the seaweed habitats in Simeulue Island are classified as highly suitable, with suitability values ranging from 64 to 82. The recorded environmental conditions collectively support optimal seaweed growth.</p>
