Improving the quality of wastewater in traditional chicken slaughterhouses using moringa seed powder

Abstract

In the city of Denpasar, Bali, Indonesia, there are hundreds of home-based chicken slaughtering industries. The slaughtering process produces liquid waste from washing chicken and equipment mixed with feces, blood, traces of protein, and fat. This waste contains high concentrations of organic material, dissolved solids, pathogenic microorganisms, and other hazardous substances that can pollute the environment. The environmental damage that occurs will adversely affect the health of humans and the surrounding animals. This study aims to determine the effect of Moringa seed powder on the quality of traditional chicken slaughterhouse waste in terms of pH, Total Suspended Solid (TSS), and Total Dissolved Solids (TDS). This study used a randomized group design with a split time pattern. The results showed that the concentration of Moringa seed powder of 200 mg/L with a deposition time of 60 minutes made the pH of wastewater close to normal pH, and also significantly reduced TSS and TDS (P<0.05). It can be concluded that moringa seed powder can improve the quality of traditional chicken slaughterhouse wastewater.
