Fertilizer (POC), which is rich in quality of liquid organic fertilizer
nitrogen, phosphorus, and
calcium. Its processing reduces
environmental impact and
increases agricultural yields.
Research by Putri and Yanda
(2021), shows that the
combination of liquid organic
fertilizer from goldfish waste and
AB Mix can increase the growth of
Pakcoy plants in a hydroponic
system and has an effect on
increasing plant height, number of
leaves, leaf area, wet weight, and
dry weight of plants.
Carp (cyprinus carpio) is
Indonesia's main export
commodity and its waste, such as
offal, head, bones, and skin, is
often thrown away. In fact, this
waste is rich in nitrogen,
phosphorus, potassium, and
micronutrients that are important
for plant metabolism and health.
processing goldfish scale waste
into liquid organic fertilizer (POC)
can improve soil fertility and plant
health, and reduce waste that has
the potential to pollute the
environment.
Dara mussel shells (Anadara
granosa) contain calcium and
phosphorus, which play an
important role for plant growth.
Research by Fernanda Ghifary
Listianto and the PKM UPNVY
team, showed that the shells of
turtle shells can be processed into
Liquid Organic Fertilizer (POC).
The POC from the shells improves
soil health, crop yields, and
reduces waste that can pollute the
environment.
EM4 bioactivator is a mixture
of microorganisms that accelerate
composting and improve the
(POC) because it contains
Lactobacillus sp., photosynthetic
bacteria, Streptomyces sp., and
yeast. EM4 Bioactivator.
Pakcoy (Brasicca rapa) is a
vegetable crop that grows quickly
in moist environments and is rich
in vitamins A, C, and K, as well as
minerals such as calcium and
magnesium and in loose, loamy
soil and soil containing good
organic matter. Due to its fast
growth and high productivity,
pakcoy is an ideal choice for POC
research, allowing rapid
evaluation of fertilizers (Smith et
al., 2017). The crop is also
resistant to variations in pH and
nutrient availability, which is
important for assessing fertilizer
adaptability (Johnson et al., 2019).
In addition, the morphological
variation of pakcoy makes it easier
to observe the impact of fertilizer
on plant growth and yield (Lee et
al., 2020).
The problems and objectives
of this study are; 1). Knowing the
effect of the combination of EM4
bioactivator and Liquid Organic
Fertilizer (POC) from the waste of
Goldfish scales (cyprinus carpio)
and Dara Shells (Anadara
Granosa) on the growth and yield
of pakcoy (Brasicca rapa) in a
hydroponic system, 2). Knowing
the long-term impact and
sustainability on plant health of
using Liquid Organic Fertilizer
(POC), a combination of
CAKEMAS and EM4 Bioactivator
on the sustainability of the pakcoy
(Brasicca rapa) hydroponic
system.
