“…This research is also trying to discover the types of film particles in various areas around Menjangan Besar waters. Six-film particles were found in Ujung Gelam beach sediments and three film particles in Legon Lele beach sediments (Lie et al, 2018). The form of microplastic films has been expected to be lower in specific gravity than other forms, especially from secondary plastic polymers resulting from fragmentation of plastic bags or plastic containers with low density, so the waves and currents toward the coast can easily carry them, and settle microplastic waste at the bottom of sedimentary waters.…”

Holothuria atra (Echinodermata: Holothuroidea) is a type of invertebrate animal that lives on the bottom of the rocky coast and has the potential as a nutritious food raw material for humans and pharmaceutical raw materials. The study aims to determine the microplastic types, microplastic functional groups and simulate the distribution pattern of ingested microplastics in the digestive system of H. atra based on hydrodynamic activity. Microplastic separation was conducted by extraction using the flotation method based on predetermined criteria. Functional group test of microplastic polymers ingested in intestines of sea cucumbers using FT‐IR (Frontier Transform Infrared‐Spectroscopy) Analysis. Hydrodynamic modeling analysis used secondary data: bathymetric, currents, wind direction, and tidal prediction data. The results of sampling of H. atra sea cucumbers at four observation locations, where ten individual sea cucumbers were taken from each location, showed that microplastic waste exposed in the intestines of sea cucumbers obtained an average value of 14,166 individuals‐1, with a particle length range of 0.214–3.978 mm. The highest abundance was from the type of fiber, followed by fragments, pellets, and films. FTIR test results indicate the presence of several functional microplastic groups that are digested in the intestine, including polyamide (PA)/nylon‐6, polyethylene (PE), polypropylene (PP), and polystyrene (PS). The movement of currents carrying microplastic waste particles is dominated to the west and south of Karimunjawa Island, potentially endangering the habitats of sea cucumbers and other animals in the waters of the surrounding small islands. It is recommended that stakeholders establish plastic waste protocols, waste facilities and treatment, and strict supervision of tourists entering the Karimunjawa tourism environment.

“…This difference is important because it can affect the degree of degradation, surface characteristics, and shape of the microplastic particles. The specific density of plastic particles varies greatly depending on the polymer and the manufacturing process (Lie et al 2018). After the mixing process, large-sized sediments will be quickly deposited while small-sized particles will remain in a state of suspension or float and can be transported by physical water factors (Hidalgo-Ruz et al 2012).…”

“…These remobilizing microplastics were buried back into the water column and might be suspended in the water column or transported back to shore (Vedolin et al 2018). The highest microplastic densities were usually associated with coastlines and physical processes in the ocean (Lie et al 2018). Diffusion of microplastics on the coast was strongly related to tides, which was caused by the accumulation of microplastics along the highest tide line, especially at high tide (Jualaong et al 2021).…”

Abstract. Embulaba O, Kolibongso D, Tapilatu RF, Saleh F, Bawole R. 2022. Distribution and types of microplastics on the coast of Aipiri and Andai Beaches, Manokwari District, Indonesia. Indo Pac J Ocean Life 6: 10-16. Plastic waste enters the marine environment in various sizes, from micrometers to millimeters. The composition and occurrence of microplastics were investigated on the Manokwari coast (Manokwari District, Indonesia) from two different beaches in terms of intensity of exploitation and exposure to various activities such as urbanization, ports, tourism, and morphological characteristics of the coast. The average abundance of microplastics was between 0.001 to 0.041 items/gram of dry sediment. Fragments and fibers are the two types of microplastics found to dominate. On the other hand, there was no substantial difference in the abundance of microplastics found on unexposed beaches with other beaches. Our results show that coastal morphology with gentle slopes with high tide limits tends to have a 'better' potential for accumulating microplastics on the beach. However, the accumulation of microplastic types is also primarily determined by the characteristics possessed by microplastics. Therefore, it causes spatial and temporal variability in the composition of microplastics found on the coast.

“…Many of these activities produce large amounts of waste and litter in coastal areas. Beach debris is an issue worldwide (Derraik 2002;Gregory and Andrady 2003;Ivar do Sul and Costa 2007;Lie et al 2018). According to the UNEP (2009), marine debris or marine litter is any durable, manufactured, or processed solid object dumped, disposed of, or left outside in the Great Lakes.…”

Abstract. Adjei O, Lamptey AM. 2021. Litter assessment at the Sakumono and La Pleasure coastal areas, Ghana. Indo Pac J Ocean Life 5: 83-91. Ghana has a difficult time managing waste, especially in the cities. The situation is even made worse in coastal urban areas by population growth. When the rains fall and wash the solid wastes downstream, most waste produced and lost inland ends up in the coastal and marine environment. In addition, revelers who use the areas for entertainment and tourism also contribute to the waste created. The Sakumono and La Pleasure Beaches in the Greater Accra Region served as the sites for this study. This study's primary goal was to assess how much waste was on the beaches at the two locations. The study made use of a transect measuring 1,000 m2. A total of 2,697 litter items were collected from the two beaches. During the survey, 50.07 kg from both sites comprised the entire weight of the litter collected. Comparatively, the amount of waste collected from La Pleasure was 18.28 kg, which accounted for 36.51% of the total amount of litter surveyed. The amount of trash collected from Sakumono Beach was 31.79 kg, representing 63.49% of the total litter surveyed. Plants were discovered to be the most prevalent material by weight and number. Plastics accounted for 72.56% of the total composition for both beaches, or 1,975 items, and 65.53% of the total composition, or 32.81 kg, respectively. In comparison to La Pleasure Beach, Sakumono Beach was found to be more littered. An alpha value of 0.05 (a p-value = 0.02) indicated this was significant. Ongoing monitoring, intensive education, and sensible policy initiatives are still essential to address the beach litter problem along Ghana's coasts.
