Abstract

Microplastics, recognized as emerging contaminants, have been detected in numerous rivers globally. This study focuses on the Ciliwung River in Jakarta, examining the influence of seasonal variations—specifically the rainy and dry seasons—on microplastics' concentration, types, and colors. Sampling was conducted during November 2022 (dry season) and March 2023 (wet season) using a plankton net for water (10 liters) and an Ekman grab sampler for sediment (400 mililiters). Microplastic abundance was analyzed following the National Oceanic and Atmospheric Administration (NOAA) adaptation method, and their material characteristics were identified using Fourier Transform Infrared Spectroscopy (FTIR) testing. Results revealed a notable seasonal impact: in the dry season, average microplastic abundance was 530 particles/liter in water and 859 particles/100 grams in sediment, whereas, in the wet season, these figures rose to 1,111 particles/ liter and 1,583 particles/100 grams, respectively. Fragments were the predominant type of microplastics, and black was the dominant color in both seasons. This consistency suggests similar sources and activities contributing year-round to microplastic pollution in the Ciliwung River.

Abstract

Ciliwung River is one of many rivers on Java Island which is polluted by waste from domestic, commercial/industrial, and agricultural activities. The rapid population growth caused changes in land use. Along with population growth and the development of human activities in various sectors, river pollution became a serious problem for humans. The purpose of this study is to conduct a spatiotemporal analysis of the concentration of pollutant in Ciliwung River and its correlation with the trend of land use changes to determine the factors that dominantly influence river pollution. The analysis was carried out on the parameters of organic pollutants (BOD, COD, DO, and TSS) using the flow and water quality data of the Ciliwung River from BBWS Ciliwung – Cisadane. Spatially, the concentration of organic pollutants increased from upstream to downstream. Meanwhile, temporally, the concentration of organic pollutants (BOD and COD) peaked in 2018 and then decreased until 2020. From the trend of land cover changes and the value of coefficient correlation, an increasing percentage of residential land caused an increasing pollutant load, indicated by a moderate-strong positive correlation test between those two variables.
