Effect of combination of beef cattle feces, dairy waste water solid, and organic kitchen waste as maggot growth media (Black soldier flies) on maggot population weight and density

Abstract

The livestock industry is closely associated with waste. On-farm waste such as beef cattle feces and off-farm waste in the form of dairy waste water solids can have detrimental effects on the environment if left untreated. The high nutrient content of livestock industry waste can be effectively utilized to prevent environmental pollution. However, the large amount of organic waste poses a significant challenge due to population density and the lack of land for waste storage or processing, which are unresolved issues. This waste can be processed through bioconversion, with the use of Black Soldier Flies (BSF) larvae representing a new method of organic waste treatment. This research was conducted at the Beef Cattle Teaching Farm and the Laboratory of Microbiology and Animal Husbandry Waste Handling, Faculty of Animal Science, Padjadjaran University. The objective of this study was to investigate the impact of combining beef cattle feces, dairy waste water solids, and kitchen organic waste on the weight and density of maggot populations. The experimental method employed four treatments with five replications each: 100% kitchen organic waste (P0), 50% kitchen organic waste and 50% beef cattle feces (P1), 50% kitchen organic waste and 50% dairy waste water solids (P2), and 33.4% kitchen organic waste, 33.4% beef cattle feces, and 33.4% dairy waste water. The conclusion drawn from this study is that the combination of kitchen organic waste and beef cattle feces contributes to an increase in maggot population density.
