Abstract

AbstractRivers in Indonesia are heavily polluted by unmanaged municipal solid waste (MSW) which affects their capacity as drinking water, power, and irrigation sources. This research aimed to analyze the effect of MSW types and contact time on the dynamics of Chemical Oxygen Demand (COD) and ammonia in the waterthat was traced over two weeks period in a batch reactor filled with Ciliwung River organic and inorganic MSW samples. Then, the MSW degradation rates to COD and ammonia (k1) were mathematically analyzed by using the mass balance principle. The results showed that for organic MSW, there were rapid increasesin COD and ammonia concentrations on the first 6 days of the experiment and followed by steady decreases. In contrast, for inorganic MSW, overall steady trends were observed for both COD and Ammonia. The analysis of the degradation rate showed that the values of K1 for COD in organic MSW was ranging from3.841 to 4.655 /day, 10-30 times higher than those of inorganic MSW values, which ranged from 0.122 to 0.425 /day. For ammonia, the values of k1 for organic MSW ranged from 0.0021 to 0.0028 /day, about two times higher than those of inorganic MSW values ranging from 0.001-0.0014 /day. Findings in this studyoffer opportunities to model and simulate COD and Ammonia dynamics in surface water due to MSW contamination.Keywords: COD, ammonia, degradation, solid waste, time effect

Abstract

AbstractOne of the causes of river pollution is the presence of waste in water bodies which causes substantial water quality deterioration. The Ciliwung River is one of Indonesia's most polluted rivers with a very high level of pollution. This study aimed to estimate the amount of daily waste generation in water bodies and theircomposition characteristics. Waste samples were taken from segment 4 of Ciliwung River, namely Jalan Juanda Depok. The waste collection method uses a trawl boom and a trap net. The results showed that the average daily waste generation in the Ciliwung River is 323.87 kg/day (standard deviation of 366 kg/day), with the composition of waste dominated by organic waste as much as 68.63%, plastic waste 15.54%, textile waste 10.89%, and other waste 4, 54%. Fluctuating composition results may be caused by weather, sampling locations, and surrounding activities. The average waste generation in Ciliwung River in theliterature is 970 kg/day. The difference in estimates is because 33 illegal waste collection points along segments 5 and 6 of the Ciliwung River are suspected of leaking into the water body. The difference in estimates is also influenced by the percentage of unmanaged waste in DKI Jakarta which was about 0.9%.Keywords: waste generation, waste composition, trawl boom, Ciliwung, waste collection
