Abstract

Abstract: Background: The problem of organic waste, especially that derived from vegetables, is a relatively important environmental issue. The accumulation of waste without proper treatment can cause pollution, unpleasant odors, and become a breeding ground for pests and diseases. Aim: a waste management strategy that is environmentally friendly and can also provide economic benefits for the village community. One innovative solution that can be implemented is to process vegetable waste into animal feed in the form of silage. Methods: The initial stage of vegetable waste inventory in Nawangsasi village, followed by silage formulation and testing its use for animal feed. Results: Silage formula was obtained by utilizing organic waste., Conclusions: The use of vegetable waste in Nawangsasi Village as animal feed in the form of silage demonstrates excellent potential to address the issue of organic waste while enhancing local feed resilience. Nawangsasi Village generates a considerable amount of vegetable waste from agricultural and market activities, which was previously often disposed of without proper control, resulting in environmental pollution. Involvement. The silage formula can be applied to farmers.

Abstract

The Production Machinery Workshop at the Sriwijaya State Polytechnic are producing a lot of aluminum scrap left over from turning, where this waste is still thrown away. This will cause pollution to the environment and will be detrimental to the Sriwijaya State Polytechnic workshop. Casting is one way to deal with aluminum scrap, scrap be melted and then reshaped into a practical material that can be reused. The use of sand as a printing medium in recycling scrolls is not recommended because it is less effective and efficient in terms of long-term use. After research has been carried out, the resulting aluminum shaving waste can be reused as practical material provided that the shavings must be separated from other waste such as iron and steel. In the optimization process, the best value is obtained at the spindle speed factor of 900 rpm (A1), then the feeding depth at 0.5 mm (B1), and the feeding speed at 0.08 mm/put. Â
