Abstract

Marine plastic debris that enters the sea can be fragmented by physical and chemical factors, then float in the water column or accumulate in sediments, which have the potential to be ingested by marine biota, causing digestive system disorders, fecundity, eating capacity, reproduction, and death. This study aimed to identify the accumulation of microplastics in water and sediments in Outer Ambon Bay using a purposive sampling method and descriptive analysis for data related to microplastics' type, color, and size, as well as follow-up tests of the least significant difference. The results show that the waters of Outer Ambon Bay have been polluted by microplastics. The number of microplastic particles found in water samples at three different depths (0, 50, and 100 cm) was 201 particles L-1, and in sediment samples, it was 325 particles g-1. It is supported by the fact that the type of fiber has a thin shape and size and can float on the surface of the water and by the existence of beaches where there are fishing activities, boat ports, rivers, and densely populated areas, as well as sandy and muddy sediments that can trap more microplastics during the tidal period. Therefore, it is necessary to prevent the waste problem in the waters of Ambon Bay. Keywords: Identification, Marine Pollution, Microplastics, Outer Ambon Bay.

Abstract

Ngurbloat Beach, located in the Kei Islands, Maluku Province, has a varied coastal ecosystem, including benthic habitats that play an important role in ecological balance and sustainability of marine resources. This study aims to map the spatial distribution of benthic habitats including substrates in the waters of Ngurbloat Beach by utilizing Allen Coral Atlas data. The analysis was conducted through classification of high-resolution satellite images using remote sensing and geographic information system (GIS) methods. The results showed that the total mapped area was 183 ha. Benthic habitats in this area are dominated by coral reefs (18.99%), seagrasses (0.85%), microalgae (2.93%) and sand substrates (16.42%), rocks (39.44%) and dead corals (22.7%). Oceanographic factors and anthropogenic activities in the waters of Ngurbloat Beach affect the distribution of benthic habitats, especially coral reefs that have suffered serious damage and need to be rehabilitated. The utilization of Allen Coral Atlas data proved effective in providing accurate spatial data for benthic ecosystem mapping, which can support conservation efforts and sustainable management of coastal resources.

Abstract

Annona squamosa L. (Annonaceae) is a tropical evergreen fruit tree with a long history of traditional use across various cultures. Its fruit, known as srikayas, is commonly consumed fresh and used in candies, ice creams, and beverages. Different parts of A. squamosa have been widely applied in ethnomedicine as tonics, apophlegmatisants, coolants, abortifacients, and heart sedatives. Phytochemical studies have identified key bioactive compounds including annonaceous acetogenins (ACGs), diterpenes (DITs), alkaloids (ALKs), and cyclopeptides (CPs), with 33 diterpenes, 19 alkaloids, 88 acetogenins, and 13 cyclopeptides reported up to 2016. Extensive research reveals A. squamosa exhibits diverse pharmacological activities such as anticancer, antioxidant, antidiabetic, antihypertensive, hepatoprotective, antiparasitic, antimalarial, insecticidal, microbicidal, and molluscicidal effects. Notably, diterpenes and acetogenins contribute to its potent anticancer properties through apoptosis induction and cell cycle arrest. Leaf and seed extracts demonstrate significant antidiabetic, anti-inflammatory, and hepatoprotective actions, while seed peptides exhibit vasorelaxant and hypotensive effects via calcium channel inhibition. This review integrates phytochemical, ethnopharmacological, and bioactivity data, highlighting the therapeutic potential of A. squamosa and encouraging further clinical studies to validate its medicinal applications.
