Processing Cow Manure Waste into Biogas as an Effort to Control Livestock Waste

Abstract

Livestock waste consists of two types of waste, namely liquid and solid. Solid waste consists of animal manure and leftover animal feed, while liquid waste consists of livestock sanitation wastewater, animal urine, and barn wash water. One example of a renewable energy source that has not yet been fully utilized is organic materials, one of which is cow dung. Cow manure can be used as a basic material in the production of biogas through an anaerobic fermentation process to generate energy. The aim of this research is to use cow dung as organic waste as an alternative energy source for biogas and simultaneously reduce the environmental pollution impact of livestock waste. The research methods used were observation and experimentation to determine how to produce biogas from cow dung waste. The research results indicate that there is a high possibility that cow dung can be used as an organic raw material to produce biogas. Methane gas can be produced during the production process starting from the 16th day after fermentation and continuing until the 25th day. A longer fermentation process results in a larger gas volume, as indicated by the daily increase in digester volume.
