SCIENCE AND TECHNOLOGY FOR THE COMMUNITY UTILIZATION OF APPROPRIATE TECHNOLOGY FOR THE DEVELOPMENT OF LIVESTOCK WASTE BIOBRIQUETTE IN SRIWULAN VILLAGE, KENDAL REGENCY

Abstract

Most of the residents of Sriwulan Village work as freelance farmers and cattle breeders. The large number of cattle breeders in Sriwulan Village has resulted in the accumulation of cow manure in several parts of the village, causing unpleasant odors. Moreover, cow manure can damage the ozone layer and contribute to global warming. One of the efforts to utilize cow manure waste is by converting it into briquettes, which can serve as an alternative energy source. Briquettes are solid fuels made from biomass containing carbon, with high calorific value and the ability to burn for extended periods. In the production of briquettes, other mixed materials are required, including other organic materials such as charcoal and tapioca flour as a binder. The community's limited access to information regarding cow manure waste management and the briquette-making process has led to an increasing accumulation of cow manure waste. The aim of this community service is to provide education and equipment to the residents of Sriwulan Village regarding cow manure briquettes and their production process until they are ready for use. This allows the community to utilize cow manure as a solution to waste problems while also improving the economy of Sriwulan Village. This initiative has successfully increased understanding and interest, especially among cattle breeders in Sriwulan Village, in utilizing cow manure for briquettes. The program resulted in briquettes with a calorific value of up to 4,941.84 Cal/g after calorific value testing.
