Researchers measured microplastic abundance and types at five sampling locations in the estuary waters of the Pemalang River in Central Java, Indonesia, finding persistent microplastic hazards driven by local human activities and plastic waste inputs.
Abundance and Characteristics of Microplastics in Surface Waters of Banten Bay, Serang, Indonesia
Researchers measured microplastic concentrations in surface waters of Banten Bay, Indonesia, across five sampling sites representing different human activities. They found concentrations ranging from 0.12 to 1.03 particles per liter, with fragments and fibers being the most common types, primarily made of polypropylene and polyethylene. The study links microplastic prevalence to domestic waste and human activities in the surrounding area.
The contribution of estuaries to the abundance of microplastics in Jakarta Bay, Indonesia
Researchers found that rivers draining into Jakarta Bay are a major source of microplastics, with polyethylene fragments in the 300-500 micrometer size range dominating, and that spatial variation in abundance across nine estuaries reflects differences in local land use and waste management.
Jenis Dan Kelimpahan Mikroplastik Pada Kolom Permukaan Air Di Perairan Teluk Kupang
This Indonesian study (in Bahasa Indonesia) measured the types and abundance of microplastics in surface water of Kupang Bay during tidal fluctuations, finding microplastics present at varying concentrations depending on tide conditions. The results contribute to documenting microplastic pollution in Indonesian coastal waters.
Microplastics analysis in Malaysian marine waters: A field study of Kuala Nerus and Kuantan
Researchers conducted the first detection of microplastics in Malaysian marine waters at Kuala Nerus and Kuantan, identifying plastic types and concentrations in surface waters from two sites representing different levels of anthropogenic activity.
Kelimpahan Mikroplastik di Perairan Pulau Temajo Mempawah Kalimantan Barat
This Indonesian study measured microplastic abundance in the waters around Temajo Island in West Kalimantan, finding widespread contamination from fibers, fragments, and films. The results contribute to mapping microplastic pollution across Indonesian coastal ecosystems, which are under pressure from both land-based and marine plastic sources.
Abundance and distribution of microplastics in tropical estuarine mangrove areas around Penang, Malaysia
This study documented microplastic pollution in tropical mangrove estuaries around Penang, Malaysia, finding thousands of plastic particles in both water and sediment samples. Concentrations were particularly high near the more urbanized Seberang Perai area, where sediment contained up to 4,000 particles per kilogram. The research highlights that tropical mangroves, which serve as important nursery habitats for marine life, are accumulating significant amounts of microplastic pollution.
Microplastic abundance and distribution in surface water and sediment collected from the coastal area
Researchers found microplastics in both surface water and sediments across 12 coastal sampling sites in Jakarta Bay, Indonesia, documenting their abundance, distribution patterns, and morphological characteristics in a heavily urbanized tropical coastal environment.
A novel report on the occurrence of microplastics in Pekalongan River Estuary, Java Island, Indonesia
Researchers measured microplastic contamination in water and sediments of the Pekalongan River estuary in Indonesia, finding concentrations of 45.2-99.1 particles/L in water and 0.77-1.01 particles/g in sediment. Polystyrene, polyester, and polyamide were the dominant polymers, with fragments and films smaller than 1 mm accounting for the majority.
The Identification of Microplastics in Karang Mumus and Karang Asam Kecil River Estuary, Samarinda
Researchers identified and characterized microplastics in the estuaries of two rivers in Samarinda, Indonesia. Microplastics were found at the study sites, adding to documentation of widespread freshwater microplastic contamination in Southeast Asian river systems.

Researchers assessed water quality and identified microplastics in a river in North Kalimantan, Indonesia, finding correlations between water quality parameters and microplastic abundance and characterizing the dominant polymer types and morphologies present.
Spatial Distribution of Microplastics Abundance Along Selected Beaches in Kelantan, Malaysia
Researchers surveyed ten beaches along the Kelantan coast in Malaysia and found over 1,600 microplastic particles, averaging about 5.4 pieces per gram of sediment, with fragments being the most common type. PVC, polypropylene, and polystyrene were the dominant polymer types, and intertidal zones were the most heavily contaminated areas. The study provides important baseline data on microplastic pollution patterns along these Malaysian coastlines, which can help guide future cleanup and prevention efforts.
