Abstract

ABSTRACTAccurate and reliable identification of macroalgae has a crucial role in a range of research relating to the interaction and function of macroalgae in reef ecosystems. The dependency on identifying macroalgae on fresh samples places severe constraints on conducting this research leading to potential biases due to the selection of sites either close to shore or in the vicinity of fully equipped research stations. Therefore, this study aimed to determine if could reliably be used silica bead-dehydrated samples to identify genera characteristics that are only visible in sectioned material. Fresh macroalgal samples were collected at Nelly Bay, compared to Magnetic Island. Materials and sections were to previously collect macroalgal samples and sections dehydrated in silica beads while in the field and reconstituted in filtered seawater for identification. Each sample was identified using histological sections supported with visual tools (photograph, herbaria). In this study, macroalgal identified samples from all species to genus with characteristic features recognizable within both fresh and reconstituted samples. No artifacts were present in reconstituted macroalgal samples compared to freshly collected samples. Therefore, it is suggested that using silica beads as a preservation field method for collecting and identifying macroalgal samples is a suitable and accurate alternative method to the use of fresh samples, which eliminates the time and distance constraints associated with fresh samples.Keywords: Great Barrier Reef, Histological sectioning, Macroalgae identification, Silica-beads preservation, Reconstituted

Abstract

ABSTRACTPlastic waste is one of the biggest problems that is difficult to deal with because plastic is strong, elastic and durable, making it difficult for nature to decompose. Microplastics are plastic particles 5 mm in size that have been degraded from their initial form over a long period of time. Microplastics can damage aquatic ecosystems and cause death to biota because they inhibit metabolic processes, can transfer harmful chemicals to biota, and so on. This study aims to determine the type, size, color, and abundance of microplastics in the gills and gastrointestinal tract of mackerel. The research method uses descriptive methods to describe a phenomenon that is currently happening and conduct observations and interviews with sellers/fishermen. This study used 30 mackerel fish from the Belawan shelter and were analyzed at the Water Quality and Fish Nutrition Laboratory, Malikussaleh University. The results showed that as many as 84 microplastic particles in the gills were in the form of fibers and dominated by black, and there were 74 microplastic particles found in the gastrointestinal tract in the form of fibers and films with black, blue, red microplastic fibers and transparent gray microplastic film colors. The sizes of the microplastics found varied and were not affected by the length or weight of the fish, gills and gastrointestinal tract.Keywords: Mackerel, gills, microplastics, digestive tract, and plastic waste.ABSTRAKSampah plastik merupakan salah satu masalah terbesar yang masih sulit untuk ditangani karena plastik bersifat kuat, elastis dan tahan lama sehingga sulit diurai oleh alam.

Abstract

ABSTRACTMap of sea surface temperature is very important in the science of oceanography, some phenomena in the ocean can be seen by using it globally. One of them is in the form of upwelling events that occur in the Banda Sea, besides that, IOD and ENSO phenomena can occur because they are close to the Indian and Pacific Oceans. Time series analysis is used to predict possible phenomena that can occur in long SST variable data. The Fourier Transform analysis obtained from the study of sea surface temperature data produces temperature signals for the dominant annual (annual) and semi-annual (6 months) periods. The ENSO phenomenon also affects temperature variations that occur in the waters of the Banda Sea with the visible signal of the inter-annual period (2.8 years). The application of the SVD-based EOF method to SST data produces a dominant EOF mode which indicates that Arafura waters play a role in influencing the SST cycle that occurs in the Banda Sea.Keywords: sea surface termperature, EOF methods, time series analysis, fourier analysis, Banda SeaABSTRAKPeta suhu permukaan laut sangat penting dalam ilmu oseanografi, beberapa fenomena di laut dapat terlihat dengan menggunakannya secara global. Salah satunya berupa kejadian upwelling yang terjadi di Laut Banda, selain itu dapat berupa fenomena IOD dan ENSO, karena berada dekat dengan Samudera Hindia dan Pasifik. Analisis deret waktu (time series analysis) digunakan untuk memprediksi kemungkinan fenomena yang dapat terjadi pada data variabel SPL yang panjang. Analisis Fourier Transfom yang diperoleh dari kajian data suhu permukaan laut menghasilkan sinyal suhu periode dominan annual (tahunan) dan semi-annual (6 bulanan). Fenomena ENSO juga mempengaruhi variasi suhu yang terjadi di perairan Laut Banda dengan terlihatnya sinyal periode inter-annual (2.8 tahunan). Penerapan metode EOF berbasis SVD pada data SPL menghasilkan satu mode EOF dominan yang menunjukkan perairan Arafura berperan dalam mempengaruhi siklus SPL yang terjadi di Laut Banda.
