Abstract

Management of water quality generated from the wastewater effluent of PT Bio Maraja Nusantara, a company that produces organic fertilizers in Makassar.. This fertilizer production activity produces liquid waste that has the potential to pollute the environment, especially local water quality. This study evaluates water quality based on Government Regulation No. 22 of 2021 concerning liquid waste management. Water quality testing measured physical, chemical, metal, and microbiological parameters. The results showed that the water quality met the quality standards set by the regulation, with the tested water not contaminated by hazardous materials such as odor, color, heavy metals, or pathogenic microorganisms. Analytical results showed the water had undetectable odor and color, low Total Dissolved Solids (TDS) content, and turbidity below the quality limit. In addition, the pH value, nitrate, nitrite, and hexavalent chrome content were also within safe limits. Microbiological testing showed the water was free from E. coli and coliform contamination. This study shows that effluent management efforts at PT Bio Maraja Nusantara effectively minimize negative impacts on local water quality and contribute to industrial water quality management literature in the sustainable agriculture sector.

Abstract

Soybean wastewater contains high levels of organic pollutans, such as high COD, TSS, and TDS values. This study aims to evaluate the effectiviness of phytoremediation using two aquatic plants species, Salvinia molesta and Azolla pinnata, in reducing pollutant levels in soybean wastewater. The experiment was conducted in a batc system using 10-liter plastic conyainers filled with 5 liters of soybean wastewater and 200 grams of each plant spesies. The study was cinducted over 7 days with samples taken on days 1, 3, and 7. The parameters measured included temperature, pH, dissolved oxygen (DO), total suspended solids (TSS), total dissolved solids (TDS), and chemical oxygen demand (COD). The results showed that Azolla pinnata significantly reduced COD levels by 65,91%. Overall, phytoremediation using Azolla pinnata demonstrated higher efficiency in improving water quality and could serve as a cost-effective and environmentally friendly treatment option for soybean wastewater.
