This study aims to determine the degradation of plastic polypropylene (PP) and identify the presence of microplastic in sediments and seawater along the Tambak Lorok coastal area. The study was conducted by collecting samples from the sea surface area, at 50 cm and 170 cm depths, while seawater and sediments were collected from six stations. The results showed an early stage of degradation because of abiotic factors. The surface morphology of plastic changed, indicating the disorientation of the plastic. Furthermore, the results demonstrated that organic carbon decreased by 3.15%, 6.67%, and 16.76% for the PP applied on surface water, at 50 cm depth and at 170 cm depth, respectively. From six stations, PP microplastic was the dominant type, where microplastic in sediment was bio-fouled fiber ranging in size from 255.23 to 1245.71 μm; however, in seawater, it was 7-111 particles/10 mL and ranged from 270.27 to 1279.12 μm in size.
本研究旨在确定塑料聚丙烯（PP）的降解情况，并确定坦巴洛克罗沿海地区沉积物和海水中微塑料的存在。该研究通过从海面、50cm 和 170cm 深度采集样本，同时从六个站位采集海水和沉积物来进行。结果表明，由于非生物因素，PP 处于早期降解阶段。塑料的表面形貌发生了变化，表明塑料发生了定向变化。此外，结果表明，PP 在水面、50cm 深处和 170cm 深处的应用分别使有机碳减少了 3.15%、6.67%和 16.76%。在六个站位中，PP 微塑料是主要类型，沉积物中的微塑料是生物污染纤维，尺寸范围为 255.23-1245.71μm；然而，在海水中，它是 7-111 个颗粒/10mL，尺寸范围为 270.27-1279.12μm。
