Assessment of floating marine debris density, composition, chemical characteristics, and recycling potential along Gajah Beach and Pasir Putih Tabing Beach, Padang City, Indonesia
AI summary Read the abstract
Researchers found that trash floating near beaches in Padang City, Indonesia nearly tripled after rainfall (washing more waste from land into the water), and plastic made up the majority of this debris, up to 90% on normal days. This matters because that ocean plastic doesn't just harm marine life and fishing; it slowly breaks down into microplastics that can end up in seafood we eat, making better coastal trash cleanup and recycling systems a public health issue, not just an environmental one.
Floating marine debris is one of the major environmental challenges affecting coastal ecosystems and marine activities. Accumulation of floating debris can interfere with fishing operations by increasing the amount of debris captured in fishing nets and reducing fishing efficiency. This study evaluated the density, composition, chemical characteristics, and recycling potential of floating marine debris along Gajah Beach and Pasir Putih Tabing Beach, Padang City, Indonesia. Floating marine debris was collected using fishing trawls under two environmental conditions: normal weather and one day after a rainfall event. Samples were collected from three sampling points representing the study area and analyzed for debris density, material composition, proximate characteristics, and recycling potential. The average debris density increased from 1.18 g/m² under normal weather conditions to 3.13 g/m² after rainfall. Five material categories were identified, namely plastic, wood, rubber, fabric, and coconut husk. Plastic was the dominant material, accounting for 90% of the debris under normal weather conditions and 50% after rainfall, with corresponding densities of 0.90 g/m² and 1.66 g/m², respectively. Proximate analysis showed average values of 25.05% moisture content, 56.33% volatile matter, 8.53% ash content, and 9.09% fixed carbon. The results also indicate that plastic, wood, fabric, and coconut husk have potential for recycling or resource recovery. These findings provide baseline information for marine debris monitoring and support the development of more effective coastal waste management and resource recovery strategies in Padang City.

Identification of Marine Debris on Marannu Beach Pasimarannu Village, Sinjai Regency

Researchers surveying a beach in Indonesia found that plastic waste—much of it still in larger, unbroken pieces—makes up most of the trash washing ashore, driven by nearby fishing, tourism, and everyday household waste. This matters because as this plastic sits in the environment, it gradually breaks down into microplastics that can enter the food chain (including seafood we eat) and pollute coastal waters people swim and fish in, highlighting why better waste management and cleanup efforts are needed to protect both ecosystems and human health.
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.
Identification of the types and characteristics of marine debris in Manado Bay, North Sulawesi Province
AI summary Read the abstract
Researchers surveyed beaches in Manado Bay, Indonesia, and found that plastic and wood debris are piling up along the coast, with plastic pollution spiking during rainy seasons when rivers wash trash into the ocean. This matters because plastic waste in the water breaks down into microplastics that can enter the seafood people eat, and the study's call for better waste management and community cleanup efforts could help reduce that contamination at the source.
Microplastic Pollution in Beach Sediments Influenced by Fishing and Tourism in Cirebon, Indonesia
AI summary Read the abstract
Researchers found tiny plastic fragments—mostly bits of plastic film from packaging—scattered across beach sediments in a busy Indonesian coastal city, largely coming from household trash washing into the ocean near fishing communities. Half of these plastic particles were smaller than 1mm, meaning they're small enough to easily enter the food chain through fish and seafood that people eat. This matters because it shows how everyday plastic waste and weak trash disposal systems can directly pollute the seafood many coastal communities rely on for food.
Semi-enclosed estuarine beaches as hotspots of marine litter accumulation: integrating seasonal assessment and hydrodynamic modeling
AI summary Read the abstract
Researchers found that beaches in a river-and-bay area on India's west coast get flooded with trash—over 90% of it plastic—especially during monsoon season, when rain washes litter from cities into the water. This matters because much of that plastic breaks down into microplastics that can end up in seafood and drinking water, and the study shows poor waste management on land is the main culprit, meaning better trash systems in cities could directly reduce the plastic pollution people are exposed to through the coastal environment and food chain.
