Perancangan Pengolahan Limbah Padi Berbasis Circular Economy untuk Meningkatkan Nilai Tambah pada CV. Hariara

Abstract

The agricultural sector, particularly rice production, generates production waste that has not been fully utilized, as seen in CV. Hariara. Based on this, the aim of this research is to apply the Circular Economy approach in rice husk waste processing and analyze the value added of the processed products using the Hayami method. This study employs a qualitative method to design the implementation of the Circular Economy based on primary data obtained through observations and interviews with CV. Hariara. Furthermore, the value added of the processed rice waste is calculated using the Hayami method, which involves determining the value added from secondary data sourced from literature, including books and journals. The results show that processing of rice waste, including rice husks, rice bran, and rice husk ash, can provide significant economic value added according to the Hayami method while simultaneously reducing the negative environmental impact. The value added generated from processing rice husks into compost additives is approximately IDR 1,883.06 per kg, processing rice husks into biochar is around IDR 816.60 per kg, processing rice husk ash into briquettes is about IDR 5,286.13 per kg, processing rice bran into animal feed is approximately IDR 3,035.48 per kg, and processing rice bran into rice bran oil is about IDR 6,864.16 per liter.
