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.

Abstract

Keberadaan ikan terumbu tentunya erat kaitannya dengan keberadaan terumbu karang karena ekosistem tersebut merupakan habitat bagi ikan karang. Terumbu karang merupakan ekosistem yang banyak terdapat di pulau-pulau kecil di daerah tropis termasuk Kepulauan Seribu. Kepulauan Seribu adalah sekelompok 110 pulau yang terletak di lepas pantai Jakarta dan hingga 80 kilometer sebelah utara Laut Jawa. Dalam studi ini, kami meneliti distribusi spesies dan keanekaragaman spesies ikan terumbu pada dua lokasi yaitu Pulau Untung Jawa dan Pulau Harapan yang berbeda jarak di Teluk Jakarta menggunakan analisis metabarcoding DNA lingkungan (eDNA). Sebanyak 4 liter sampel air laut dikoleksi pada kedalaman 8-9 meter per lokasi lalu dilakukan analisis menggunakan primer spesifik (MiFish U) dengan marka 12s rRNA. Secara keseluruhan, kekayaan spesies yang lebih tinggi ditemukan di Pulau Harapan (52 spesies) diikuti oleh Pulau Untung Jawa (11 spesies). Indeks Shanon-Wiener juga menunjukkan bahwa Pulau Harapan memiliki keanekaragaman ikan terumbu yang lebih tinggi berdasarkan tiga tingkatan taksonomi (famili, genus, dan spesies). Hanya ada lima spesies ikan terumbu mutual yang ditemukan di dua lokasi tersebut, yakni Atherinomorus aetholepis, Auxis thazard, Cephalopholis sexmaculata, Epinephelus chlorostigma, dan Plectropomus areolatus. Hasil temuan dalam penelitian ini sejalan dengan perbedaan antropogenik dimana Pulau Untung Jawa lebih dekat dengan Teluk Jakarta dibandingkan dengan Pulau Harapan yang letaknya relatif jauh dari Teluk Jakarta.

Abstract

The Halmahera Walking Shark (Hemiscyllium halmahera) is an endemic marine biota in the Halmahera Sea. This species has a local migration pattern and is territorial. The distribution of this species is in the intertidal area to a depth of 10-15 meters. Previous studies have shown that this species is spread across several islands in the North Maluku Islands. Maitara Island is a small island located between the North Maluku archipelago. The Halmahera Walking Shark species is also found on this island. Information on the Halmahera Walking Shark species is not fully documented. The purpose of the study is related to biological information and emergence points (emergence points) in the Maitara Island Sea. Data collection was carried out on coral reefs, seagrass and mangroves. Samples were captured and morphometric measurements, weight and sex observations were taken. The sea area where the species was found was used to obtain coordinates for the emergence point. An analysis of length-weight relationship data was carried out to see growth patterns. The study found that morphometric measurements varied among individuals, although there were general similarities. Sexes were found in pairs (Male and Female), indicating that proportions and mating were still normal in nature. The habitat of this species is found in the mangrove area, coral reefs, and seagrass, thus describing that there is an association in nature. The emergence point shows that the Halmahera Walking Shark is found along the coast of Maitara Island although the frequency of the number is different. The length-weight relationship found a negative allometric growth pattern. Information on biological aspects and emergence points is important, to be used as a reference for migration areas and habitats for the interests of species, waters, and ecosystem conservation.  Hiu Berjalan Halmahera (Hemiscyllium halmahera) merupakan biota laut endemik di laut Halmahera. Spesies ini memiliki pola migrasi lokal dan bersifat teritorial. Penyebaran spesies ini di wilayah intertidal hingga kedalaman 10-15 meter. Penelitian terdahulu menunjukan bahwa spesies ini tersebar di beberapa pulau di Kepulauan Maluku Utara. Pulau Maitara merupakan pulau kecil yang terletak diantara gugusan kepulauan Maluku Utara. Pulau ini juga ditemukan speises Hiu Berjalan Halmahera. Informasi belum terekam lengkap terkait spesies Hiu Berjalan Halmahera. Tujuan penelitian terkait informasi biologi dan emegence point (titik kemunculan) di Laut Pulau Maitara. Pengambilan data dilakukan di terumbu karang, lamun dan mangrove. Sampel ditangkap dan diambil ukuran morfometrik, berat dan pengamatan kelamin. Area laut ditemukannya spesies diambil koordinat untuk di jadikan sebagai titik kemunculan.  Analisis data hubungan panjang-berat dilakukan untuk melihat pola pertumbuhan. Hasil penelitian ditemukan ukuran morfometrik bervariasi pada setiap individu, meskipun terdapat kemiripan secara umum. Kelamin ditemukan sepasang (Jantan dan Betina), dengan demikian menunjukan proporsi dan perkawinan masih normal di alam. Habitat tertangkap spesies ini di area mangrove, terumbu karang dan lamun, sehingga mendeskripsikan terdapat asosiasi di alam. Titik kemunculan menunjukan bahwa, Hiu Berjalan Halmahera ditemukan di sepanjang pesisir laut Pulau Maitara meskipun frekuensi jumlah berbeda. Hubungan panjang berat menemukan pola pertumbuhan allometrik negatif. Informasi aspek biologi dan emergence point penting, untuk dapat dijadikan rujukan wilayah migrasi dan habitat untuk kepentingan konservasi spesies, perairan dan ekosistem.

Abstract

Restorasi terumbu karang adalah serangkaian upaya ilmiah dan manajerial untuk memulihkan ekosistem terumbu karang yang rusak akibat faktor alam dan aktivitas manusia. Teknik restorasi yang digunakan termasuk transplantasi karang, pembuatan terumbu karang buatan, dan pengendalian stresor lokal seperti polusi, overfishing, dan perubahan iklim. Kegiatan restorasi di Indonesia telah dilaksanakan di lebih dari 500 titik dalam 30 tahun terakhir, melibatkan ribuan unit terumbu buatan dan jutaan fragmen karang. Namun, banyak dari kegiatan ini tidak menunjukkan keberhasilan yang ditandai dengan kegagalan.  Faktor peningkatan suhu laut, persaingan dengan alga atau spons, serta faktor manusia menjadi penyebab utama. Saat ini, Indonesia belum memiliki standarisasi untuk menilai keberhasilan restorasi terumbu karang. Oleh karena itu, penting untuk mengembangkan parameter dan indikator yang dapat digunakan untuk menilai efektivitas dan keberhasilan kegiatan restorasi, guna memastikan keberlanjutan ekosistem terumbu karang.

Graphical Abstract Highlight Research 1. This research provides initial and current information regarding seagrass on small islands right on the equator. 2. directly depicts the diversity, density and cover of seagrass in a unique region, namely a small island crossed by the equator. 3. The environmental conditions of marine waters in seagrass areas on islands crossed by the equator have been described. 4. The latest information specifically describing seagrass and the ecology of equatorial marine environments. Essential for the development of future knowledge and technology. 5. DNA barcoding was capable of resolving field identification challenges and providing taxonomic clarification based on DNA sequence data.   Abstract The equator is a hypothetical line that separates the general region from the world.  Complete information on coastal ecosystems has not been provided for seagrass in the equatorial latitudes. Seagrass is dynamically distributed throughout the equatorial latitudes. The area that the equatorial latitudes also traverse is known as the indotropic region. Eastern Indonesia's Kayoa Island is situated directly on the equator.  A problem, namely how is the biodiversity of seagrass in the equatorial region. There are no published research on seagrass, particularly on biodiversity. The aim of this study is to reveal the diversity of seagrass in equatorial latitudes on the small islands. The methodology in this study was purposive sampling with a quadrant line transect was used to obtain the samples.  In situ identification of seagrass species was done.  Seagrass samples were taken from the leaves for DNA analysis purposes. Leaf samples were analyzed molecular in the laboratory. To determine the distribution of seagrass ecology and environmental were subjected to PCA analysis. The results found that six species of seagrass.  It has been discovered that seagrass may grow and develop in the tropical region under typical environmental conditions.  Despite the fact that six species were discovered, diversity was limited.  In this region, seagrass cover is typically high and supports a healthy species density.  In general concluded that diversity and density are low but cover is still quite good. DNA barcoding has revealed differences in morphological identification.This discovery represents preliminary data that can be investigated further in subsequent studies.
