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

Environmental conditions and community activities impact surface water and groundwater quality. Physical, chemical, and biological parameters can be used to assess water quality so that i can be used by established quality standars. This study aimed to assess the quality of surface water and groundwater around the Samarinda State Agricultural Polytechnic using TDS, pH, COD, Fe, and Zn parameter sat eight different sampling locations. Water quality assessment based on physical and chemical parameters follows the guidelines of Goverment Regulation No. 22 of 2021. Based on the research results, the TDS value range is 61 mg/L – 320 mg/L; the pH value range is 5,4 – 7,97; the COD value range is 136 mg/L – 208 mg/L; the Fe value range is between 21,4 mg/L and 27,3 mg/L, and the Zn value range is between 0,89 mg/L and 1,44 mg/L. This indicates that some water quality parameters, including COD, Fe, and Zn, do not meet the quality limits set by Government Regulation No. 22 of 2021.
