Abstract

The negative impact of domestic waste water discharge is a decrease in water quality in the receiving water body due to reduced dissolved oxygen, which can result in the death of aquatic organisms. Increased concentrations of BOD (Biological Oxygen Demand), COD (Chemical Oxygen Demand), and TSS (Total Suspended Solid) in domestic waste can have a negative impact on the environment through a series of interrelated processes such as triggering the phenomenon of eutrophication, where algae growth becomes uncontrollable and disrupts the balance of aquatic ecosystems. When BOD and COD levels increase, it indicates an excessive accumulation of organic matter and pollutants in the water, resulting in a decrease in dissolved oxygen due to oxygen consumption by microorganisms that decompose the organic matter. Several previous studies related to the quality characteristics of domestic wastewater were analyzed to determine its quality in the parameters of BOD, COD, and TSS. As a result, most of the domestic wastewater quality has a quality that exceeds the required quality standards. The average quality of domestic wastewater in the parameters of BOD, COD, and TSS is 541.9 mg/L, 1318.4 mg/L, and 1986.8 mg/L, respectively. The BOD and COD ratio shows 0.4, domestic waste must go through the seeds to be decomposed.

Abstract

Wastewater produced by health facilities such as Community Health Centers has great potential to pollute the environment, especially due to the high levels of Biological Oxygen Demand (BOD) and phosphate. Phytoremediation, using plants such as Eichhornia crassipes and pumice, is an efficient, environmentally friendly, and economical waste treatment method. The purpose of this study was to analyze the effectiveness of Eichhornia crassipes and pumice plants in phytoremediation tests on community health center wastewater with BOD and phosphate parameters. This type of research is a true experimental using a One group pretest and posttest design. The sample in the study was Community Health Center wastewater with a sample size of 10 L. BOD and phosphate levels were measured on days 0, 3, 6, and 9 to determine the effectiveness of phytoremediation in reducing pollutant levels. The data analysis used univariate. The results showed that BOD levels decreased significantly from 21.08 mg/L on day 0 to 10.36 mg/L on day 9 with a decrease rate of 51%. In addition, phosphate levels also decreased from 0.95 mg/L to 0.28 mg/L with a decrease of 71% after 9 days of treatment. Phytoremediation using Eichhornia crassipes and pumice wood is effective in reducing BOD and phosphate levels in Puskesmas wastewater. Suggestions for further researchers are the development of time variations and combination methods, exploration of other plants, the influence of environmental factors, larger scale tests.
