Microplastic Contamination in the Waters of the Jebung River, Sungai Nibung Village
AI summary Read the abstract
This Indonesian study identified and characterized microplastics in the Jebung River at Sungai Nibung Village, a coastal area where plastic waste from human activity degrades and enters the aquatic environment. The research contributes baseline contamination data for a region where microplastic monitoring is still emerging.
Plastic waste has become a national and international issue. Plastic waste will degrade into smaller sizes, such as microplastics. Microplastic contamination can occur in coastal and marine areas which can have a negative impact on the environment, disrupting the balance of the ecosystem and aquatic biota. Sungai Jebung located in the coastal area of Desa Sungai Nibung, has the potential to microplastic pollution. This research aims to identify the type, density and type of polymer of microplastics in Sungai Jebung, Desa Sungai Nibung, West Kalimantan. Water sampling was carried out at three stations with two repetitions. Identification of microplastic types was carried out using a binocular microscope and polymer analysis was done using FTIR. The types of microplastics found in the water samples consisted of films, fibers, fragments and pellets. Film and fiber have a higher percentage compared to other types. The average total density of microplastics was 3,188.94 particles/L. The types of polymers found include polyethylene (PE), polystyrene (PS), and polytetrafluorethylene (PTFE).

Occurrence and visual characterization of microplastics from Mahakam River at Tenggarong City, Indonesia
AI summary Read the abstract
Researchers detected and visually characterized microplastics in water samples from the Mahakam River near Tenggarong City, Indonesia, contributing to limited freshwater microplastic data from the country that produces approximately 7.8 million tons of plastic waste annually. Microplastics were found in river samples, with fiber and fragment morphotypes dominant, reflecting local plastic waste mismanagement.

AI summary Read the abstract
Researchers measured microplastic abundance in the Batanghari River in the Nipah Panjang area of East Jambi, Indonesia. Microplastics were found in river samples, with the community's practice of dumping plastic waste into the river identified as a key source. The findings call for improved waste management and public education in communities adjacent to Indonesian rivers.
Microplastics abundance in the surface water of way-belau river, lampung province, indonesia
AI summary Read the abstract
Microplastics were detected in the Way-Belau River in Lampung Province, Indonesia, providing baseline contamination data for a region of Sumatra that had not previously been surveyed. Fibers were the most common type found, likely from domestic wastewater and textile activity in surrounding communities. The study fills a data gap for Indonesian rivers and highlights the need for broader freshwater monitoring across the archipelago.
