The air pollution in Jakarta has been recorded regularly; meanwhile, the information of atmospheric microplastics is still unknown. This study examines the characteristics (shape, size, and polymer) and deposition rate of atmospheric microplastics in Jakarta. The sample was obtained by putting a rain gauge for 12 months. All microplastic samples were analyzed for polymer using FT-IR. The lowest to the highest percentage of atmospheric microplastic based on shape were foam<fragment<fiber, meanwhile based on size were of 500-1000 μm < 300-500 μm. The detected polymers included polyester, polystyrene, polybutadiene, and polyethylene. The microplastics deposition rate ranged from 3 to 40 particles md, with an average of 15 particles md. The rainy season's deposition rate (23.422 particles md) was higher than the dry season (5.745 particles md). Our study proves that the atmospheric microplastic exists in Jakarta's air and needs to be considered to monitor by the government regularly.
雅加达的空气污染已被定期记录，但大气中微塑料的信息仍不清楚。本研究检测了雅加达大气中微塑料的特征（形状、大小和聚合物）和沉积速率。样品通过放置雨量计收集 12 个月获得。所有微塑料样品均使用傅里叶变换红外光谱（FT-IR）分析聚合物。根据形状，大气微塑料的最低至最高百分比依次为泡沫<碎片<纤维，而根据大小则依次为 500-1000μm<300-500μm。检测到的聚合物包括聚酯、聚苯乙烯、聚丁二烯和聚乙烯。微塑料的沉积速率范围为 3 至 40 个粒子 md，平均为 15 个粒子 md。雨季的沉积速率（23.422 个粒子 md）高于旱季（5.745 个粒子 md）。我们的研究证明，大气中的微塑料存在于雅加达的空气中，需要政府定期进行监测。
