Abstract :
- 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.
