- The implementation of the circular economy in Indonesia has received special attention from the government. This is evidenced by the existence of a circular economy implementation master plan made by the government until 2025. The circular economy is a concept of processing waste into a product, and then the product is reused for raw materials or additive materials. In the mangrove nursery business, leaves, litter, and mangrove twigs in the form of waste are processed to become vermicompost with the help of L. Rubellus worms. Physico-chemical analysis showed that during the vermicomposting process, the N, P, and K content increased while the pH, organic total and C/N ratio decreased. Study results show that vermicompost is useful for increasing soil fertility, increasing the number of microbes in the soil, increasing the nutrients in the soil and increasing plant growth. Economic analysis shows that the vermicompost business using 840 kg of earthworms and 10,000 Kg of compost costs 4000 USD., generates profit, and the BEP point is reached in the seventh month.
