Abstract

Due to its unique coastal characteristics, the Aroen Meubanja Turtle Conservation Area in Aceh Jaya has significant potential as a nesting site for sea turtles. This study analysed the area's sand grain size and characteristics to determine its suitability for turtle nesting. The research was conducted in March 2024, with sand samples collected from three stations using purposive random sampling. Laboratory analysis included sieving and sand grain classification based on size and shape using the Wentworth and Powers classifications. The Wentworth scale is used to classify grain size, while the Powers scale assesses the shape and roundness of the grains. The results revealed that over 70% of the sediment in the area consists of very fine sand, which is highly favourable for turtle nesting. The roundness of the sand grains indicates a long transportation process, contributing to their suitability for nesting. Fine sand allows for proper water drainage, preventing waterlogging in nests and maintaining optimal temperatures for egg incubation. Additionally, environmental factors such as beach width, slope, substrate temperature, humidity, and coastal vegetation further enhance the area's potential as a turtle conservation site. This study concludes that the Aroen Meubanja coastal area meets the criteria for an ideal turtle nesting habitat. Recommendations include habitat management, community education, and further research to ensure sustainable conservation efforts

Abstract

Antimicrobial resistance has become one of the most serious global health threats, prompting the search for new natural sources of antibiotics. Marine biota, such as algae, sponges, and bacteria, are known to produce a variety of secondary metabolites with potential biological activity, particularly as antimicrobial compounds. This review article examines the bioactive potential of these marine biota as an alternative source of natural antibacterial compounds. The study was conducted by reviewing various international and national literature related to the bioactive metabolites produced, their mechanisms of action against pathogenic bacteria, and the potential for their use in developing new antibacterial agents. The results of the review indicate that sulfated polysaccharides, terpenoids, alkaloids, and phenolic compounds from algae; alkaloids, cyclic peptides, and terpenoids from sponges; and secondary metabolites of marine symbiont bacteria have significant antibacterial activity, including against antibiotic-resistant bacteria. However, the development of marine bioactive compounds still faces various obstacles, particularly related to isolation techniques, mass production, and environmental sustainability issues. Therefore, modern biotechnological approaches, such as genomics, metabolomics, and synthetic biology, are needed to optimize the utilization of these marine resources. This article confirms that marine biota are important candidates for the development of new, sustainable antibacterial agents and have the potential to support the strengthening of the blue economy concept.

Abstract

Leiognathus daura is a small pelagic fish that plays an important role in coastal ecosystems and has economic value for local communities. This study aimed to analyze the length–weight relationship, condition factors, and morphological characteristics of L. daura as a basis for fisheries biology information. A total of 30 specimens were examined morphometrically and meristically. The length–weight regression produced the equation y = 0.9073x + 0.2776 with a coefficient of determination (R²) of 0.2595. The value of b = 0.9073 (< 3) indicates a negative allometric growth pattern, meaning that length increases faster than body weight. Condition factors showed a Fulton's K value of 3.8036 and a relative condition factor (Wr) of 101.0081, suggesting that the fish population is healthy and supported by a favorable aquatic environment. Morphologically, L. daura has a laterally compressed body, small terminal mouth, large eyes, silvery scales, and a forked caudal fin, all of which support schooling behavior and adaptation to shallow coastal waters. The low R² value implies that body weight is influenced by length and environmental conditions, food availability, reproductive status, and fishing pressure. These findings highlight the importance of understanding the biological aspects of L. daura as a foundation for sustainable fisheries management in coastal ecosystems

Abstract

Epiphytic macroalgae are phototrophic organisms that attach to rigid substrates in the intertidal zone and serve as key components of coastal ecosystem structure due to their roles in providing habitat, stabilizing substrates, and supporting nutrient cycling. This study aimed to inventory the types of epiphytic macroalgae present in the rocky intertidal zone of Padang Unoi Village, Salang District, Simeulue Regency. Observations were conducted in July 2025 along a 150-m transect, dividing the area into two tidal zones: the lower littoral and the mid-littoral. The inventory revealed seven species of epiphytic macroalgae, namely Turbinaria sp, Sargassum sp, Padina sp, Chaetomorpha aerea, Caulerpa taxifolia, C. racemosa, and Amphiroa subcylindrica. Species from the Phaeophyta division dominated the mid-littoral zone, while Chlorophyta were more abundant in the lower littoral zone, and Rhodophyta were observed on coarse-textured rocky substrates. These three major divisions indicate habitat heterogeneity that supports the growth of various types of epiphytic macroalgae. The results of this study highlight the importance of the rocky intertidal zone of Simeulue as a productive habitat and provide a basis for sustainable coastal resource management

Abstract

Chaetomorpha sp is a type of green marcoalgae that is rich in bioactive compound that function as antibacterial, anti-inflammatory and can increase fish immunity. This study aims to determine the immunostimulating effect of Chaetomorpha sp macroalgae extract on the leukocyte profile of Tilapia infected with A. hydrophila. The experimental method used a completely randomized design (CRD) with four extract dose treatments (0, 25, 50, 75 mL/kg feed) and three replicates. The test fish used were 2.63 0.26g, reared in black tanks with a size of 60x30x30 cm, a volume of 80 L with a stocking density of 1 fish/4 L, and a recirculation system. Maintenance was carried out for 60 days with a frequency of feeding three times a day, namely 08.00 AM, 01.00 PM, and 05.00 PM, as much as 5% of body weight. The parameters observed were total leukocytes, leukocyte differentiation, and phagocytosis index. The results showed that the administration of Chaetomorpha sp extract significantly increased total leukocytes, lymphocyte differentiation, and phagocytosis index (p0.05). The dose of 50 mL/kg feed is the optimal dose that affects the leukocyte profile of Tilapia. T0 (without extract) experienced 100% mortality, while the treatment group showed increased resistance to infection. Bioactive compounds such as sulfated polysaccharides and flavonoids in Chaetomorpha sp are thought to play a role in stimulating the innate immune system. This study highlights the potential of Chaetomorpha sp as an alternative to antibiotics in sustainable tilapia aquaculture.

Abstract

Penelitian ini bertujuan untuk menganalisis persentase tutupan lamun di perairan Pulau Weh, khususnya di pesisir Pelabuhan Balohan, Sabang. Pengambilan data dilakukan menggunakan metode transek kuadran pada dua titik pengamatan. Transek kuadran ukuran 50x50 cm diletakkan dengan jarak 5 m pada garis pengamatan sepanjang 30 m. Hasil penelitian menunjukkan bahwa hanya satu jenis lamun ditemukan di lokasi penelitian, yaitu Halodule uninervis, yang dikenal memiliki kemampuan adaptasi tinggi terhadap lingkungan berpasir dan arus tenang. Nilai kerapatan lamun berkisar antara 145–484 individu per kuadran, dengan persentase tutupan masing-masing 31% pada titik 1 dan 69% pada titik 2. Faktor lingkungan seperti kecerahan dan pH menjadi penentu utama perbedaan tutupan, di mana kecerahan lebih tinggi (1,6 m) dan pH basa (9,3) pada titik 2 mendukung pertumbuhan vegetatif lamun yang optimal. Kondisi tersebut menunjukkan bahwa kualitas perairan, khususnya tingkat kecerahan dan pH, memiliki pengaruh signifikan terhadap produktivitas H. uninervis di habitat pesisir tropis. Hasil penelitian ini dapat menjadi dasar dalam upaya pengelolaan dan konservasi ekosistem lamun di wilayah Sabang secara berkelanjutan.
