ClearMajor sources and monthly variations in the release of land-derived marine debris from the Greater Jakarta area, Indonesia
This study tracked monthly variations in marine debris discharged from the Greater Jakarta area in Indonesia, identifying land-based sources including rivers and coastal communities as major contributors. Peak discharge events correlated with rainfall patterns, highlighting the importance of monsoon-season waste management in reducing ocean plastic pollution.
Strategic action for waste management in Manado City to prevent marine debris input to Manado Bay: a preliminary study
Researchers conducted a preliminary assessment of waste management practices in Manado City, Indonesia, to identify strategic actions for preventing marine debris from entering Manado Bay. The study recommended both short-term mitigation and long-term management interventions to reduce the ecological, public health, and aesthetic impacts of marine debris in this coastal urban environment.

The form and distribution of microplastic in sediment and water columns of Manado Bay, North Sulawesi
Microplastics were detected in both water and sediment samples from Manado Bay in North Sulawesi, Indonesia, with a variety of shapes including fragments, fibers, and pellets. The contamination reflected inputs from land-based plastic waste and coastal activities. The study documents the extent of microplastic pollution in an Indonesian coastal bay and highlights risks to local marine ecosystems.
Mitigation of marine debris from land: Formulation of the best options for managing marine debris in the coastal city of Manado, Indonesia
This study analyzes marine debris sources and management options in Manado City, Indonesia, with the goal of protecting the adjacent Bunaken Marine Park. Effective coastal debris management is essential for reducing the flow of plastic waste — a precursor to microplastics — into sensitive marine protected areas.
Microplastic Identification and Density In Coastal Sediments of Manado Bay
Researchers identified and quantified microplastics in coastal sediments of Manado Bay, documenting the density and polymer types of plastic particles accumulating in the marine environment from anthropogenic activities.
Effects of seasonal variation on the characteristics of stranded marine debris within Rambut Island Wildlife Reserve, Indonesia
A survey of marine debris on the beaches and mangroves of Pulau Rambut Wildlife Reserve in Indonesia found that plastic dominated debris loads, with single-use plastics like styrofoam, sachets, and packaging most prevalent. The study provides baseline data showing that even protected wildlife areas accumulate substantial plastic pollution, underscoring the need for upstream plastic reduction to protect sensitive coastal and mangrove ecosystems.
Seasonal variation in plastic litter pollution in mangroves from two remote tropical estuaries of the Colombian Pacific
Researchers found that plastic litter in two remote Colombian Pacific mangrove estuaries was dominated by microplastics, with higher abundances during high-rainfall seasons in both surface waters and sediments, and foams and fragments being the most common types.
The abundance of Plastic Marine Debris on Beaches in Ambon Bay
Researchers measured plastic marine debris — including large microplastics, mesoplastics, and macroplastics — on two beaches in Ambon Bay, Indonesia. The study provides baseline data on plastic pollution levels in a region with growing coastal populations and limited plastic waste management infrastructure.
Kepadatan dan pola transport sampah laut terapung di pesisir barat perairan Teluk Ambon Luar
This Indonesian study measured the density and transport patterns of floating marine litter on the western coast of Outer Ambon Bay, finding high volumes of plastic debris with clear spatial patterns driven by currents and tides. The data can inform placement of debris interception systems in this Indonesian coastal city.
Spatial and temporal distribution of microplastic in surface water of tropical estuary: Case study in Benoa Bay, Bali, Indonesia
Seasonal sampling of microplastics in Benoa Bay, Bali found no significant wet/dry season difference, with the highest MP abundance near the Suwung landfill and fragment-shaped particles (73%) dominating, suggesting landfills and river discharge are primary local sources.
The impact of improper solid waste management to plastic pollution in Indonesian coast and marine environment
Indonesia's plastic pollution problem in coastal and marine environments is largely driven by improper solid waste management on land, with rivers carrying significant plastic loads to the sea. The study emphasizes that improving terrestrial waste collection and disposal infrastructure is essential for reducing Indonesia's substantial contribution to ocean plastic pollution.
Sources, spatial distribution, and abundance of marine debris on Thondi coast, Palk Bay, Southeast coast of India
Researchers surveyed marine debris abundance and composition on Thondi coast in Palk Bay, India, finding that plastic was the dominant litter type linked to local fishing, aquaculture, and agricultural activities, with seasonal variation in debris loads.
Short-term Observation on Marine Debris at Coastal Areas of Takalar District and Makassar City, South Sulawesi-indonesia
Researchers surveyed marine debris on coastal areas in Takalar District, Indonesia, finding plastic as the dominant material type. Short-term monitoring of beach litter provides baseline data for understanding local plastic inputs to the ocean.
Analysis of Weight, Composition, Density, and Recycling Potential of Floating Marine Debris in Pasie Nan Tigo Area, Padang City
This Indonesian study analyzed the weight, composition, and recycling potential of floating marine debris collected in Padang City coastal waters. Plastic was found to dominate the floating debris, and the study assessed which materials could be recovered through recycling programs to reduce marine plastic pollution.
