Abstract :
In today's modern era, human population growth and development continue to increase, accompanied by a corresponding rise in waste disposal, including organic waste. Organic waste, derived from natural organic materials, can have adverse effects on the environment and health. Organic waste falls into wet (such as fruit and vegetable residues) and dry categories (including paper, wood, branches, and dry leaves). These wastes can be processed into compost, additional animal feed, handicrafts, and biogas. The design method employed involved field observations in the BTN Serunai residential area in Kota Dumai, where it was found that approximately 117 kg of organic waste is generated daily from 90 households, highlighting the urgent need for effective waste management strategies. This design proposes the development of a household-scale organic waste shredder machine to reduce environmental pollution. The results of this design utilized a 0.5 Hp motor with a rotation speed of 1400 Rpm to rotate the shaft and cutting blades. The average shredding time for waste was 2.70 minutes, producing an average particle size of 5 mm. This average size was obtained by sieving shredded waste through a 5 mm mesh. The benefits of this design include facilitating the process of cutting organic waste in household environments. This organic waste shredder machine at the household scale can be beneficial for communities in reducing waste volume, especially organic waste.
