Abstract

Sponges (Phylum Porifera) are a group of highly diverse, sessile, and filter-feeding basal metazoans, except spongillids. The majority of sponges are marine species that play an important role in benthic habitat by maintaining the stability of marine ecosystems through nutrient cycling, habitat provision, and bioerosion. However, marine sponges are not easily identifiable because of their lack of species-level distinctive morphological features, which limits efforts to monitor actual species biodiversity. Indonesia is home to approximately 850 identified species of marine sponges, and Raja Ampat archipelago of West Papua province is known for its exceptional marine biodiversity. Despite the species abundance, the exact number of sponges in the region is not well-documented due to the lack of specific studies providing comprehensive data on their diversity. Therefore, this study aimed to conduct a DNA barcoding analysis using the mitochondrial cytochrome oxidase I (COI) gene as a marker, combined with morphological analyses of 22 individuals collected in the waters of Waigeo, Mansuar, and Gam Islands in Raja Ampat. The results showed that 3 samples were identified at the species level (Halichondria sp. and Stylissa carteri) with good query cover and percent identity. This showed the possible presence of undescribed or cryptic species, suggesting a severe lack of reference data for both morphology and molecular analyses of marine sponges in the region. Consequently, the analysis showed the presence of a significant gap in the understanding of sponge biodiversity in Raja Ampat's waters.

Abstract

The Halmahera Walking Shark (Hemiscyllium halmahera) is an endemic species in the Halmahera Sea. Information related to the environment in general has not been described in a complex manner. The environment is the main factor to support the life of biota. Environmental characteristics are a determining factor in the sustainability of biota. The study aims to provide information related to the physical environment of the habitat of the H. halmahera species. Primary data collection was carried out directly (in situ). Current data was taken using the Lagrange method using a currents drogue. Tides using tidal palms and observed for 24 hours. Secondary data was taken from Marine Copernicus and the Geospatial Information Agency (BIG). All data were tabulated and analyzed by Ocean Data View (ODV) software. The results of the study found that the surface current velocity was found to be in the fast current category. Current speed descriptively provides information on the life of H. halmahera. Primary data shows that the direction of the surface current moves to the east and north. Secondary data in vertical distribution shows weak zonal and meridional current shifts. The tidal pattern was found to be two high and low tides (semidiurnal). The distribution of surface temperature was found to be around 30-32oC. The vertical temperature profile found three layers, namely 1-13m (30oC), 65m (25oC) and 71m (20oC). The chemical environment showed all normal variables. The physical and chemical environmental conditions support H. halmahera to inhabit the sea area of Morotai Island. The environmental description has provided a brief understanding of how the ecological role of the H. halmahera species. Management and sustainability of the environment in the future due to climate change can be done with information on habitat characteristics.Keywords:coral triangleHalmaheranicheNorth Malukutropical

Abstract

Dugong merupakan mamalia laut yang termasuk dalam ordo Sirenia, dan tergolong organisme langka yang tercatat dalam IUCN.  Rendahnya populasi dugong disebabkan oleh faktor biologi reproduksinya, perburuan oleh manusia, dan kerusakan habitatnya.  Dugong diketahui memiliki pola makan sebagai herbivora, dan menghabiskan waktu untuk aktivitas makan di padang lamun.  Penelitian terdahulu terhadap isi perut dugong di Indonesia menyebutkan bahwa, 90% perut dugong berisi daun lamun jenis Thalassia hemprichii, Halodule sp., Halophila sp., dan Cymodocea sp., sementara sisanya adalah rumput laut. Tujuan dari penelitian ini adalah untuk mengetahui distribusi padang lamun sebagai habitat pakan dugong, dan ancamannya di Indonesia.  Penelitian ini dilakukan sepanjang Tahun 2012, di 15 pulau kecil wilayah perairan Negara Kesatuan Republik Indonesia (NKRI).  Metode yang digunakan dalam penelitian ini adalah kombinasi transek garis (Line Intercept Transect-LIT) dan transek kuadrat di setiap stasiun ditemukannya padang lamun.   Hasil penelitian menunjukkan bahwa lamun jenis Thalassia hemprichii, Halodule sp., Halophila sp., dan Cymodocea sp. ditemukan di seluruh stasiun pengamatan.  Keempat jenis lamun tersebut ditemukan membentuk padang lamun monospesies maupun heterospesies, dengan kondisi kualitas perairan yang relatif baik untuk tumbuh dan berkembang biak.  Padang lamun sebagai habitat pakan dugong yang ditemukan  selama penelitian di 15 pulau kecil diketahui memiliki ancaman lingkungan beragam, antara lain proses sedimentasi dan konversi lahan oleh manusia.

Abstract

Abstract Ternate Island is located on the North Maluku Sea. The North Maluku Sea region includes the Wallacea area and the world's coral triangle. One of the organisms commonly found in this sea is red algae. Study aimed to determine the red algae species by phylogenetic tree analysis based on the rbcL gene as a DNA marker. The preserved red algae tissue samples were extracted with the Geneaid GP100 DNA Extraction Kit Plant. The DNA sample was amplified and then visualized by 1% agarose gel electrophoresis. The amplicon products were sequenced and then aligned with the rbcL gene database that was available at the NCBI gene bank. The phylogenetic tree was constructed using the UPGMA method. The results showed that red algae were identified into four species: namely Gibsmithia hawaiiensis (98.65%), C_rbcL sample was identical to Amansieae sp. (91.50%), D_rbcL sample was identical to Peyssonnelia sp. (95.54%), and G_rbcL sample was similar to Portieria hornemanniI (96.15%). Based on phylogenetic tree analysis, Gibsmithia hawaiiensis from North Maluku is closely related to species from Raja Ampat, West Papua, Indonesia, followed by the Philippines species. Special findings were found to carry out phylogenetic reconstructions that can answer inter-species kinship. The general finding is that the markers used can be used for phylogenetic construction. Phylogenetic construction of Peyssonnelia sp. in North Maluku is related to species from South Africa. North Maluku's Portieria hornemannii is closely related to a species from Korea. Highlight Research This study provides initial information about the DNA barcoding of red algae. Important for management purposes and determining the status of red algae in the future. This scientific information also provides an understanding of the relationships among red algae species in the world's oceans. Global warming has changed the temperature of seawater and affected the population of marine organisms.

Abstract

The sea sponge Stylissa carteri plays an important role because it is one of the constituent biota of coastal and marine ecosystems, especially in coral reef ecosystems. The increasing utilization of bioactive compounds in sea sponges is feared to significantly reduce the population of sea sponges. The prevention effort involves cultivating sea sponges for sustainable utilization. This study aims to determine the antioxidant activity of transplanted Stylissa carteri sponges and those that live naturally in nature. This study was conducted in Pramuka Island using the sponge explant combination method. The three types of transplants were number one (SO), number two (S. carteri and Aaptos suberitoides), and number three (S. carteri, A. suberitoides, and Acropora hard coral). Antioxidant activity was tested with three repetitions on three transplanted and naturally occurring S. carteri sponges (SA) using the DPPH (1,1-Diphenyl-2-Picrylhydrazyl) method. The results indicated that the four sample sources contained strong antioxidant activity, namely SO had an IC50 value of 86.22±23.6 μg/mL, SAP 86.58±30.7 μg/mL, SAC 86.10±23.4 μg/mL, and natural living SA 54.27±16.9 μg/mL. The transplanted S. carteri sea sponge has strong antioxidant activity and can be an alternative solution in terms of raw material availability for the development of potential pharmaceutical products.
