Abstract
The high risk of the Coronavirus disease (COVID-19) pandemic has caused the government set a various of policies to limit citizen mobility. The imposition of this mobility restriction has a significant impact on the environment. This study aims to analyze several physic-chemical waters parameters in Kadia River during the first year of the COVID-19 pandemic. The results of this study indicate that temperature, turbidity, DO at low tide and BOD exceed the required quality standard. The contribution of household domestic waste is very likely to have an effect on the height of some of these parameters, because in the first-year people are more active at home (work from home). The other parameters (DHL, pH, NO2, PO4) are still within the quality standard threshold level. Therefore, it is necessary to control and manage waste water from urban domestic so that the sustainability of river ecosystems can continue in the future.

Summary
Berdasarkan Tabel 1, nilai suhu (temperatur) pada air Sungai Kadia pada titik T1 sebesar 36,2 oC, titik T2 sebesar 29,5oC, titik T3 sebesar 29,4oC, dan titik T4 sebesar 24,9oC. DHL tinggi berarti saat pengambilan sampel air kondisi perairan sedang dalam keadaan keruh yang mengindikasikan banyaknya senyawa organik atau ion-ion lain yang dapat menghantarkan listrik. Buangan limbah domestik dan non domestik dapat juga meningkatkan parameter air sungai yang lain yaitu oksigen terlarut (dissolved oxygen/ DO). Pada pengamatan oksigen terlarut (dissolved oxygen/ DO) pada air sungai Kadia menunjukkan nilai DO pada titik T1 sebesar 0,11 mg/L, titik T2 sebesar 0,17 mg/L, titik T3 sebesar 0,21 mg/L dan titik T4 sebesar 70,3 mg/L (Gambar 5). Nilai DO mengalami peningkatan secara signifikan pada titik T4 disebabkan karena pada titik ini merupakan bagian hilir sungai dan kebolehjadian sungai telah tercemar oleh akumulasi hasil buangan limbah domestik dan non domestik
