Abstract

Banyaknya industri yang berkembang dewasa menyebabkan meningkatnya kadar logam berat seperti merkuri dalam perairan. Penelitian ini bertujuan untuk mengetahui pengaruh [Hg (NO3)2] dengan konsentrasi yang berbeda terhadap benih ikan kakap putih (L. calcarifer): histologi insang. Dalam penelitian ini, ikan dipaparkan dengan konsentrasi 3,16 x 10-2 ppm, 9,99 x 10-2 ppm, 3,16 x 10-1 ppm dan 9,97 x 10-1 ppm. Total ikan yang digunakan untuk histologi adalah 15 ekor. Hasil penelitian menunjukkan bahwa semakin tinggi konsentrasi [Hg (NO3)2] maka kerusakan pada jaringan insang ikan juga akan meningkat dan mempercepat waktu kematian ikan. Kerusakan yang terjadi yaitu hipertropi dan hiperplasia pada sel epitel insang, fuse pada lamela sekunder dan haemorhage di insang pada konsentrasi [Hg (NO3)2] yang lebih tinggi.Many industries today lead to increased levels of heavy metals such as mercury in water. This research aims to determine the effect of different concentrations of [Hg (NO3) 2] to Asean Sea Bass (L. calcarifer): Gill Histology. In this study, this fishes was treated with 3,16 x 10-2 ppm, 9,99 x 10-2 ppm, 3,16 x 10-1 ppm, and 9,97 x 10-1 ppm. Total fishes used for histological study was 15 fishes. Results of this research showed that increasing the consentrations of the [Hg(NO3)2] will also increase the damage on the stomach structure and fasten the mortality time of the fish. Damage that occurs is hypertrophy and hyperplacia on epitel cells, fuse of secundary lamellae and haemorhage on gill that were exposed to high consentration of [Hg(NO3)2].

Abstract

Kajian terhadap populasi mangrove Rhizophora stylosa di Desa Kuala Langsa Kota Langsa dilakukan pada bulan November 2021 dengan tujuan untuk mengetahui distribusi geografi, struktur demografi, morfometrik organ dan karakteristik penciri morfometriknya. Data dikumpulkan dengan menarik transek kuadran berukuran 10 x 10 m yang tegak lurus garis pantai, dimana penentuan stasiun pengamatannnya berdasarkan purposive sampling. Organ daun, buah dan bunga diambil pada 5 tegakan pohon di masing-masing plot, kemudian diukur morfometriknya. Untuk struktur demografi, pengelompokkan umurnya dianalisis menurut metode Bhattacharya dan untuk penciri morfometriknya dianalisis berdasarkan statistik Principal Component Analysis (PCA). Hasil kajian memperlihatkan bahwa distribusi geografinya tergolong berlimpah (frekuensi relatif di atas 80%) dan pengelompokkan umurnya hanya terdiri dari satu kelompak dengan kisaran nilai tengah diameter batangnya antara 2,30–12,44 cm. Morfometrik diameter buah yang dominan ditemukan adalah 1,05–1,11 cm, panjang buah 26,46–27,77 cm, lebar kelopak bunga 0,38–0,41 cm, panjang kelopak bunga 0,98–1,04 cm, lebar daun 5,50–5,77 cm, panjang daun 11,60–12,11 cm dan diameter batang 5,41–7,00 cm. Selain itu, panjang buah, panjang kelopak bunga dan diameter batang merupakan morfometrik pencirinya dengan keragaman data 82,73%. In November 2021, a study was conducted on the Rhizophora stylosa mangrove population in Kuala Langsa Village, Langsa City, with the objective of determining the population's geographical distribution, demographic structure, morphometric organs, and morphometric characteristics. The data were collected by pulling a 10 x 10 m quadrant transect parallel to the shoreline, with the observation station determined through purposive sampling. Leaf, fruit, and flower organs were collected from five tree stands in each plot and then measured morphometrically. Battachraya method was used for the demograpic structure and Principal Component Analysis (PCA) was used to determine the morphological characteristics. The study's findings revealed a widespread geographic distribution (relative frequency greater than 80%) and a single age grouping with median stem diameters ranging from 2.30-12.44 cm. The dominant fruit diameter morphometrics were 1.05–1.11 cm, fruit length 26.46–27.77 cm, petal width 0.38–0.41 cm, petal length 0.98–1.04 cm, leaf width 5.50–5.77 cm, leaf length 11.60–12.11 cm, and diameter stem 5.41–7.00 cm.

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.

Abstract

Microplastic contamination in marine environments is a growing concern, particularly in fish species consumed by humans. This study investigates the presence and characteristics of microplastics in the livers of Indian mackerel (Rastrelliger kanagurta) and yellowtail scad (Atule mate) collected from Pahang and Kelantan. The abundance of microplastics was quantified for each species at each location, with the total count normalized by the number of fish analyzed following the extraction and identification process. Microplastic identification was conducted using a Stereoscopic Microscope, while polymer composition was determined through ATR-FTIR spectroscopy. The microplastic abundance recorded was 0.067 particles per fish. The microplastic identified were predominantly fragments and filaments in red, black, and grey colors. The polymers found were poly(diallyl phthalate) (PDAP), poly(butylene terephthalate) (PBT), polypropylene (PP), poly(cyclohexylenedimethylene terephthalate) (PCT), and high-density polyethylene (HDPE). The finding of microplastics in fish livers provides preliminary evidence of contamination and suggests direct exposure of these vital organs. This raises serious concerns about potential contamination in other crucial organs, including the gills, gastrointestinal tract, tissues, and even the brain. This highlights the need for further research on microplastic exposure pathways and its ecological implications along the east coast of Peninsular Malaysia.

Abstract

The most crucial aspect of managing an ecosystem or habitat is knowledge about accompanying biota, such as snails. The research on mangrove snails in the KPH Region III Aceh City of Langsa area was conducted in November 2021 with the goal of evaluating species diversity, density, ecological index, distribution, and their link to surrounding environmental conditions. Snail data was obtained via quadrat transects, with observation stations established using purposive sampling.The snail diversity was found to be five species from four families, with the highest density found in N. planospira (03.13 ind/m2). The diversity index was low (H' ‰¤ 2.0), dominance was moderate (0.5 < C ‰¤ 0.75), and uniformity tended to be balanced (0.5 < E ‰¤ 0.75). The distribution pattern is clustered (Iδ> 1), with C. cingulata being abundant (83.33%), and C. capucinus being frequently found (50.00%), N. planospiraonly found occasionally (36.11%), and L. scabra and T. telescopium are relatively uncommon (11.11% and 0.56%, respectively), with a link to environmental variables indicating that T. telescopium prefers fine mud substrates. Meanwhile, C. cingulata, C. capucinus, L. scabra, and N. planospiralive in habitats with fine mud substrates that are more solid than T. telescopiums habitats.

Abstract

The study was conducted between August and September of 2021 in order to determine the density, ecological index, distribution pattern, geographic distribution, environmental factors, and the relationship between hermit crabs and environmental factors. Hermit crabs were gathered using a quadratic transect and sample plots, while environmental variables were measured in situ. PCA and CCA multivariate statistics were used to determine the characteristics and correlation between hermit crabs and environmental factors. Hermit crabs were discovered to be comprised of two species (Clibanariuslongitarsus and C. infraspinatus) and one family (Diogenidae), with the highest density found in the C. longitarsus species (1.22 ± 0.57 - 4.68 3.53 ind/m2), diversity index is categorized as moderate (2.0<H‰¤3.0), the dominance is low (0<C‰¤0.5), the distribution pattern is clustered (Iδ>1), the geographical distribution is abundant (>80%), and environmental factors are categorized as good. In addition, Stations I and II have high DO, TOM, mangrove density, C. longitarsus, and C. infraspinatus parameters, whereas Station III has high salinity, pH, and temperature, with salinity, mangrove density, and TOM being the most influential parameters on hermit crab density.

Abstract

Water quality is one of several aspects that affect the success of aquaculture business. This study analyzes water quality and assesses its impact on aquaculture enterprises in the Rancong pond region of Lhokseumawe City. The study ran from November to December 2018. The water quality of the Rancong pond was sampled directly and tested in multiple labs. The field survey and purposive sampling strategy separated the research location into four stations with three water sampling points. Temperature, salinity, turbidity, brightness, pH, dissolved oxygen, alkalinity, total organic matter, BOD5, total ammonia nitrogen, nitrite, nitrate, phosphate, lead (Pb), total Vibrio bacteria, total general bacteria, and phytoplankton types and abundance were measured. The suitability of water quality is assessed using descriptive analysis, scoring, and matching. The investigation indicates that the quality and maintenance of the source water are highly suitable (S1). Traditional vannamei shrimp ponds in Rancong, Lhokseumawe City, should be maintained as fisheries cultivation areas.

Abstract

Tropical marine environments are abundant and diverse; therefore, shark and ray research at fishing port PPS Lampulo, Banda Aceh City was carried out focusing on morphometric characteristics and differences based on multivariate analysis in July 2020 to identify sharks and rays that landed at fishing port PPS Lampulo, Banda Aceh City and determine their primary characteristics. The shark and ray samples used were from the Indian Ocean and the Malacca Strait and measured total length (TL), fork length (FL), and standard length (SL) for sharks and disc width (DW), TL, and disc length (DL) for rays. Principal component analysis (PCA) and discriminant analysis (DA) were performed on the morphometric data. The PCA analysis revealed that sharks and rays caught in Pelabuhan Perikanan Samudera (PPS) Lampulo, Banda Aceh City, can be divided into two distinct groups. The first group of sharks consists of species with large FL and SL morphometrics, namely P. kamoharai, C. plumbeus, P. glauca, and A. superciliosus. The second group of sharks consists of species with large TL morphometrics, specifically A. pelagicus and C. plumbeus. For the ray group, the first group comprises species with large TL and DW morphometrics, represented by A. ocellatus. The second group of rays consists of species with large DL morphometrics, namely P. sephen and H. jenkinsii. The results of DA revealed distinct differences in the size of sharks caught in the Indian Ocean and the Strait of Malacca, specifically in PPS Lampulo, Banda Aceh City. However, no significant differences in size were observed for the rays, regardless of whether their size was measured using DW, TL, or DL.

Abstract

The increasing use of mercury in the industrial sector poses significant risks to freshwater ecosystems and aquatic organisms. Milkfish (Chanos chanos), a widely consumed species, is now being reared in freshwater environments, raising concerns about mercury bioaccumulation and food safety. This study aimed to determine the median lethal mercury concentration for milkfish at 96 hours (LC50) in freshwater using an experimental approach and probit analysis. Five mercury concentrations were tested: 0 (control), 0 .110 mg Hg/L, 0.195 mg Hg/L, 0.347 mg Hg/L, and 0.618 mg Hg/L. The results indicated that mercury is highly toxic to milkfish, with a 96-hour LC50 of 0.147 mg Hg/L. Clinical symptoms observed included loss of reflex movements, irregular swimming, frequent surfacing with widened mouth and operculum openings, convulsions, and ventilation of the ram before mortality. These findings highlight the acute toxicity of mercury in freshwater milkfish and underscore the potential health risks associated with mercury contamination in aquaculture systems.
