TOOLS AND MATERIALS

1. Fishery Waste
Fishery wastes, such as;
goldfish scales (cyprinus
carpio) and conch shells
(Anadara granosa), have
significant potential as Liquid
Organic Fertilizer (POC)
materials. 4. EM4 Bioactivator
EM4 Bioactivator (effective
microorganisms) bioactivator
is an ingredient that helps
speed up the process of
making Liquid Organic
Fertilizer (POC) and improve
its quality. EM4 is also useful
2. Goldfish for improving soil structure
Goldfish (cyprinus carpio) is a and texture and fulfilling the
fish that has high economic nutrients needed by plants,

and fat. The components
contained in fish have an
influence on nutrition, functional
properties, sensory quality and
