“…Mangroves are the main source of carbon, vitamins, minerals, proteins, essential fatty acids, and energy that can be utilized for organisms and humans. Mangrove ecosystems have contributed to primary productivity in the aquatic environment in the form of leaf litters [2] [3] and the litter experiences decomposition [4]. Mangroves contain various chemical compounds that can be used as medicine [5]; spawning grounds and nurseries for many fish and mollusks [6 -8].…”

Amino acids are important components of mangrove plant metabolisms. The aim of this study was to determine the relationship of mangrove R. mucronata leaf colors to the amino acid content. This study was conducted between March to August 2019. The leaves were taken 50 g. The assessment of Amino acids was conducted using UPLC Waters Acquity Class H with PDA Detector. The principal component analysis (PCA) was used to determine the relationship analysis between R. mucronata leaf colors and amino acid concentrations. The largest content was L glutamic acid with a green leaf content of 6139.57 ± 694.17 mg/kg and yellow leaf content of 6105.013 ± 113.2058 mg/kg. The results of PCA 1 showed that the influential amino acids were L-threonine (0.94), L-tyrosine (0.96), L-alanine (0.92), L-vanin (0.93), and PCA 2 showed glutamic acid (0.91). These results indicated that the difference in mangrove leaf colors affects the amino acid contents in the leaves.

Principal component analysis displays data in the form of graphs, and data matrices, which consist of research zones as productivity (lines) and environmental variables and (columns) [21]. This analysis shows the relationship between variables and produces a biplot graph representation [22].…”

The connectivity between seagrass and mangrove ecosystems has synergistic benefits of conserving the land-sea ecosystems of the small islands. The physicochemical properties of the two ecosystems lead to the success of the habitat of the interconnected zone. This study aimed to analyze the physicochemical factors in the mangrove and seagrass ecosystems on Pramuka Island and understand the factors influencing the phytoplankton production of small island coastal ecosystems. Sediment and water collection were carried out on Pramuka Island, Indonesia, to measure physicochemical parameters. Mangrove and seagrass ecosystems have the highest DO, temperature, and pH values. The phytoplankton counts showed significant variation between the sampling sites with a predominance of the class Cyanophyceae. The estimated primary productivity of chlorophyll-a indicated that its concentration was higher in mangroves than in seagrass. A similar trend was observed in nutrient loads and dissolved inorganic nitrogen. Results of the present study clearly showed that an increased concentration of dissolved inorganic nutrient influence the concentration of chlorophyll-a as an indicator of primary productivity. These findings will provide a preliminary analysis of the physicochemical conditions and productivity on Pramuka Island.

“…There are many marine ecosystem specifications in Indonesia, namely coral reefs, seagrass (Unsworth et al, 2018), seaweed (Pringgenies et al, 2020) and mangrove ecosystems (Ariyanto et al, 2020). Each of these ecosystems has a high level of biodiversity because all three have different environmental characteristics (Ariyanto et al, 2019a), secondary metabolite (Ariyanto et al, 2019b;Ningsih et al, 2020) and marine organisms (Ariyanto et al, 2018;Santosa et al, 2020). These three ecosystems have certain ecological functions, one of which is as a habitat for vertebrate and invertebrate organisms such as sponges.…”

Sponges are marine organisms that have associations with microorganisms. The association fungi in sponges have a chemical and ecological relationship. These bioactive compounds have potential in the pharmaceutical field. This research aimed to explore bioactive compounds of association fungi in sponges that live in coral, seaweed and mangrove ecosystems. The research consisted of isolation, purification, extraction, antibacterial testing, molecular identification, antioxidant testing and toxicity testing. The research was conducted on March to September 2020 in Karimunjawa Island. The results showed that the sponge association fungi isolates had antibacterial activity against the Multi Drug Resistant (MDR) pathogens Staphylococcus aureus (Sa), Escherichia coli (Ec), and Staphylococcus epidermidis (Se), Pseudomonas aeruginosa (Pa) and the fungi Candida albicans (Ca). The identification results of the active association fungi were Circinelloides sp., Xylariaceae sp., Trichoderma asperellum, Aspergillus sp. and Pleosporales sp. . The extracts of these fungi had antioxidant activity with an IC50 value of 1071,62; 643,35; 1020,32; 805,70 and 784,31 mg/L. Furthermore, they also had an LC50 value of 462,67; 355,47; 504,92; 482,15 and 435,88 mg/L. Keywords: Antimicrobial, Antioxidant, Fungi, Sponge, Symbiosis
