Mapping Analysis Distribution of Microplascticat the Tallo River in Macassart
AI summary Read the abstract
Researchers used geographic information system mapping to analyze the spatial distribution of microplastic contamination in sediments along the Tallo River in Makassar City, Indonesia. The results showed that microplastic abundance varied across the river catchment and was influenced by proximity to urban activity zones.
This aims of the study to identify spatial microsplastic pollution sediments in the Tallo River Makassar City. This type of research is descriptive observational. This research design uses a Geographical Information System (GIS) Statistical analysis using the average abundance of microplastics is presented in tables and graphs, then analyzed descriptively quantitatively at each station. Data showing the mean ± standard deviation were analyzed using SPSS software. Based on the results of research that has been done, the number of microplastics found in the sediments in the Tallo River is 289. The highest microplastic size found in the Tallo River sediments is 1.00-4.75 mm as much as 167 MP (58%) with an average abundance of 18, 56 ± 30,875 MP/kg. Followed by a size of <1 mm as much as 112 MP (39%) with an average abundance of microplastics 12.44 ± 17.686 MP/kg and sizes> 4.75 mm as much as 10 MP (3%) with an average abundance of microplastics 1.11 ± 2,315 MP/kg.

Spatial Dynamics of Microplastic Pollution in Water and Sediments of the Ciliwung River along with Conditions of Water Quality Field Parameters and Population Density
AI summary Read the abstract
This study mapped the spatial distribution of microplastics in water and sediment across Indonesia's heavily populated Ciliwung River, finding significant contamination linked to population density and land use. The dominant types were fragments and fibers from textiles and synthetic materials, with concentrations varying along the river's length. The results underscore the threat that densely settled riverine systems pose as conduits of microplastic pollution into coastal and marine environments.
