Crushing Power of a Corn Cob Chopping Machine for the Manufacture of Animal Feed at the Cinagarabogo People’s Livestock Centre, Subang Regency, Indonesia

Abstract

Process of making animal feed at the People’s Husbandry Centre (SPR) Cinagarabogo Subang Regency is one of the producers of ruminant animal feed for cattle. The ruminant feed made from corncob waste is distributed to cattle breeders in Subang Regency. The manufacture of animal feed made from corn cobs is still done conventionally, so that the fulfilment of ruminant feed needs is often hampered. This study aimed to design a disc mill machine that is used to crush corn cobs. The research method started from observing, sketching, making 2D and 3D designs, and conducting expert validation. Based on the research, it can be concluded that the design made has been declared valid with a score of 87% or was in the proper category. Further recommendations that the design is feasible to proceed to the manufacturing process.
