CONCENTRATION AND CHARACTERISTICS ANALYSIS OF SUSPENDED ATMOSPHERIC MICROPLASTICS IN THE MATERIALS RECOVERY FACILITY AREA
In 2023, plastic waste was the second largest contributor to waste in Indonesia, amounting to 6.79 million tons annually. Microplastics can be generated at solid waste facilities, from reception, sorting, and separation to processing due to compression, friction, and mechanical abrasion. Micropla...

| Summary: | In 2023, plastic waste was the second largest contributor to waste in Indonesia,
amounting to 6.79 million tons annually. Microplastics can be generated at solid
waste facilities, from reception, sorting, and separation to processing due to
compression, friction, and mechanical abrasion. Microplastics are plastic
particles < 5 mm. Microplastics have become a global issue due to their potential
effects on the human body and environmental ecosystems. This study aims to
analyze the concentration and characteristics of suspended atmospheric
microplastics at the solid waste facility, specifically at IPST Sabuga. The study
began with TSP sampling according to SNI 7119-3:2017, followed by identifying
suspected microplastics, sample pretreatment, and microplastic identification.
The concentration of microplastics was found between 4.22 - 6.95 MP/m³. The
identified microplastic shapes were fibers (78%), fragments (18%), and films
(4%). The size distribution of microplastics ranged from 22 to 4,912 ?m, with an
average size of 694 ?m. The identified microplastic colors were black (70.1%),
white (6%), transparent (3.4%), red (3%), green (2.2%), blue (4.1%), and brown
(11.2%). Then, one of the black fiber microplastic based on Raman spectrum
analysis match 92,64% with a composite material, made from 28% of Gallium
Arsenide, 25% of Van dyke brown, 17% of Thermolite-380, 16% of Lanthanum
Chloride Hydrated, and 14% of Goethite. Spearman correlation tests showed
results (p-value<0.05 & 0.60<rs< 0.71), indicating a significant relationship with
strong correlation values between variables in the form of fibers with black color,
films with white color, and white with transparent color. |
