Design and Fabrication of Double Actions of Agricultural Waste Chopper: a Community Empowerment Inspired

Agricultural waste is huge in the villages as a by-product of harvesting. Without proper management, they become useless or even a danger to the society and environment. This paper aims to describe a report on the community service activities of the authors in an attempt to resolve the agricultural waste in the Villages of Sempu-Banyuwangi and Arjasa-Jember, East Java, Indonesia. Two types of wastes were identified: cattle dungs and by-products of the agricultural harvests. These two wastes would be chopped or crushed to reuse either as compost or cattle feed. Therefore, a double function machine was designed and manufactured. The main cutters were made of a used chainsaw blade. A strainer was added to sieve the crushed cattle dung. This machine was powered by a 6.5 HP gasoline engine. Both cattle dung and agricultural waste could be crushed or chopped into small pieces. It is double hoppers: upper and side for different tasks.
