Microplastic Distribution in Sediments in Coastal of Pariaman City, West Sumatera Province
Indonesian researchers surveyed microplastic distribution in sediments along the coast of Pariaman City, West Sumatra, finding plastic particles throughout the study area. Higher concentrations near tourism areas and residential zones suggest that local human activities are the primary sources of coastal microplastic contamination.
Microplastic Pollution in Indonesia: The Contribution of Human Activity to the Abundance of Microplastics
This systematic review of Indonesian microplastic research found that coastal and marine sediments have the highest microplastic abundances, driven by widespread use of cheap single-use plastics and poor waste management across urban and rural areas.
Microplastics in the tropical Northwestern Pacific Ocean and the Indonesian seas
Researchers measured microplastic abundance in the tropical Northwestern Pacific and Indonesian seas, finding very low concentrations in open-ocean currents but an order of magnitude higher levels in the Indonesian straits due to river runoff and current convergence patterns.
Abundance, characteristics, and distribution of microplastics in Banda Sea and Seram Sea, Indonesia
Researchers measured the abundance, characteristics, and distribution of microplastics in the surface waters of Banda Sea and Seram Sea, Indonesia, finding concentrations ranging from 4.69 to 22.48 items/L with an average of 14.07 items/L. Fibers, fragments, and pellets of PET, HDPE, LDPE, PVC, PP, and nylon were detected, with highest abundances near Ambon city and lower concentrations in open deep-sea areas due to reduced anthropogenic influence.
Microplastic abundance and its relationship with sediment grain size in seagrass and bare flats of Panjang Island, Banten Bay, Indonesia
Researchers surveying Panjang Island in Indonesia's Banten Bay found microplastics throughout both seagrass and bare sediment areas, with finer-grained sediments accumulating more particles. Seagrass beds appeared to trap more microplastics than bare areas, meaning these critical coastal habitats — already under stress — may concentrate plastic pollution and expose the organisms sheltering in them to higher doses.
Abundance and Types of Microplastics in the Water of Sukaraja
Researchers quantified microplastic abundance and types in the coastal waters of Sukaraja, Indonesia, using random sampling at three stations during high and low tide in April 2021. A total of 3,600 particles/m3 were recorded, with fragments being the most abundant type (1,466 particles/m3) and film the least, with the highest concentrations near the main plastic waste accumulation zone.
Microplastics in the surface sediments from the eastern waters of Java Sea, Indonesia

Microplastic contamination during the peak of upwelling in Maluku Sea, Indonesia
Microplastics are widespread even in the open ocean upwelling zones of Indonesia, where nutrient-rich deep water rises to the surface. Researchers found an average of 7.6 microplastic items per liter in surface waters and over 300 items per kilogram in deep-sea sediments of the Maluku Sea — with fragments and fibers dominating, and tire-related rubber polymers notably present. The findings suggest that ocean circulation patterns in these ecologically vital fishing areas are actively concentrating and redistributing plastic pollution, with implications for marine food webs and fisheries management.
