October is really coming off as a more relaxed month
for most of us.
September was a really frantic month for the AACN
team. As such, we would like to apologize for missing
the September issue. Although we are not going to give
any excuses, you will soon see in the October issue that
we had good reason for our apparent slackfullness.
However, to make it up to you all, we will be publishing
a Special Feature newsletter next month, in addition
to the November Issue.
True contentment is a thing as active as
agriculture. It is arduous and it is rare

Banana Harvesting
Had my first banana harvest in early October. It
was actually 60 days early if according tocalculation. Based on Jabatan Pertanian
guidelines, it usually fruits 8-9 months after
planting and matures in 100-120 days. Come to
think of it my only input for the banana trees are 3
products, which are Fermented Organic Material
(FOM), SP 2 & Micron-Ca.
The Banana Collector harvesting the banana by
pulling the fruit down and making 2 sharp cuts oneach side of the banana trunk.

After harvesting, we cut the trunk down and leave
it to rot. While we keep 2-3 suckers for the next
round of harvest.

Dont know if this is proper post-harvest handling
but he shields the banana with newspaper so
there is less friction on the bananas.
The price of Berangan banana are great. Ex-farmis about RM 2.00/kg. While Pasar Malam &
Hypermarket are selling them between RM 3.50
RM 4.50/kg.
Have fun farming. See you again in next months
issue.

My Little Farm 10
Project Papaya V3
We use to have a couple of these during my
childhood days. Well guess things are not what it
used to be. Had been having problem with the
weather, causing drought and wet stress on the
plants. Then there is pest infection as well as
fungus infection.
Our second batch trial on Papaya started back on
April. Germinating the seeds I guess was the easy
part. I have faster germination and higher
germination rate by germinating on a raised bed. I
prefer this method as I find that it suits my local
condition better as our water supply is
inconsistent. Raised beds retain more heat and
moisture that small germination tray. I didnt have
much luck using germination tray. We had some
problem with chickens (neighbors) scratching onthe raised beds and ants carrying away seeds
during the germination period. Heavy drops of
water / rain also created problem like toppling the
seedling. This can be taken care of by putting
shading net over it, a few inches higher than the
raised bed. My guys are doing this, but I took the
lazy way out, doing the raised bed underneath a
tree, and blocking it with whatever waste that is
available, such as old wood, bamboo & etc.
This time, I transferred the seedlings to poly bags
after they germinated with 2 to 4 leaves. It is very
tender at this stage. I feel that I am getting higher
survival rates after transfer as there are so young
and adaptive, or maybe they are too nave and is
easy to cheap. I find using poly bags of 6 inchesdiameter X 9 inches deep provides more space for
the root to grow and retain more heat and
moisture. We can keep the seedling to even to a
foot tall in this size of bag. Also its not too large or
heavy to transport for field planting. These
seedlings are kept under a shade of 70%. Correct
amount of watering at this stage is critical. Too
much, fungus attack, too little it gets dried off.
Depending on the weather and field condition, I
transfer them to field at a height of 5 inches andabove.

Once transferred to field, irrigation is also very
critical for the first two months. We encountered
some problem as it was hot and dry during, then
sudden rain for some time. Also we need to water
the plants as sometimes its real hot. All these
factors caused the stem to break up, infecting the
stem with fungus / bacteria. This caused stem /
collar rot. We had some plants dying, died. We try
saving the plants but at the same time, planted
another one next to it.
We had some mealy bugs attack. Fruit flies are
also a plenty. We had started to wrap up the
papayas.
Then came Fungus attack, Anthracnose and
Powdery Mildew.
We also tried planting about 200 papaya plants,
integrating it with pumpkins. As we were short of
workforce and it was left uncared for a while. The
weeds had grown too long. We are having a tough
time weeding them. It can only be done manually
with hand, as we do not want to damage the
pumpkins and papaya. The pumpkins had borne
some fruits, but due to the dry season and long
weeds, the harvest was mostly damaged but rats.
The weeds did helped by shading the papaya and
help keep the soil moist. Had started to clear the
weeds, but plenty more to go. Dont think we can
clear it before I go off for my vacation. Had
requested my helpers to follow through on the
weeding and fertilizing.

We have some papayas starting to flower and
started to have small fruits. Need to do some
fertilizing. The 3 surviving Mas Solo are growing
healthily. We hope for these 3 to bear fruits so that
we can propagate more of these variety should it
pass our screening.
Special thanks to Michael J, whom had offered
plenty advice.
Stay tune for more updates.

Fish Scales Jelly for Osteoarthritis and Beauty Care
It has been a while people talking about fish
scales jelly, and they begin to use of deep sea
fish scales that are discarded in commercial
fishery, then recycle into useful healthy healing
dessert soup or making jelly for consumption.
By using deep sea fish scales to cook into jelly
dessert, or making healthy soup, the gelatin-like
property in fish scales is cooked and derived the
hydrolysis of collagen extract, which has the rich
calcium content and collagen property to bone
health as they believed this is folk medicine
remedies which can be good for osteoarthritis to
elderly and other health purposes.
Deep Sea Fish Scales (Dried and cleaned)
Fish scale has good source of natural collagen
contains and is one of the most critical raw
materials for the biotechnology industry to produce
into marine collagen and gelatin, which is well
known now like skincare collagen capsules and
collagen beverages. Also, a huge demand for the
best biomedical materials include bio-materials,
cosmetics, food, industrial, and research
purposes. It can be nutritious supplement to hair,
bone and teeth, also good nutrients for beauty
health care to support the skin layers required to
active and further enhanced collagen in the skin,
to moisturize the skin, anti-aging, helps in
eliminating wrinkles and other effects from the
marine collagen derived in form of collagen
beverage and capsules.

What is Collagen?
Collagen is a complement nutrient and building
block to skin and helps to slow down aging. it is
about 30% of entire protein of the human body,
weight about 3 kg of collagen in an adult body.
Collagen is essential protein widely present in thehuman skin, bone, muscle, tendons, cartilage,
joints, hair tissue acts as a support, repair, and
protection triple anti-aging effects.
There are many benefits and its nutrients like
mineral, fat, protein, iron, zinc, and variety of
vitamins, calcium, phosphorus, and collagen
extracted from fish scales. Which is good for bone
and teeth, entire human body and its structure
functions. And its mechanisms of action to use fish
scales extracted into gelatin jelly dessert as good
sort of natural collagen for beauty and health care.
It can be skin miniaturization and anti-
wrinkle natural skincare to prevent skin
aging
Helps to improve arthritic conditions,
osteoporosis for elderly and improve
calcium absorption
Improving of hair care and preventing from
dryness, hair-loss and baldness Helps to replenish and improve to enhance
skin tone, promoting skin scars and repairs
wound healing.
As good natural source of collagen to
promote self-production of collagens and
hyaluronic acid playing a role in keeping
skin firmness and improve skin moisture
retention.
It also enhances immunity system.
A friend of mine has been collecting large amount
of biggest deep sea fish scales from the wet
market or fisheries. I can see he is real keen in
doing it for years, and he thoroughly removed the
entire stink and foul-smelly with properly
procedures, from brushing each fish scale, it really
taking his precious times to clean up the wet fish
scales one by one, to dry it and the whole process
of preparation, then make it into dried fish scales.
He then preserved it for storage in future usage.
Anyway, nowadays you can easily find the dried
fish scales selling in market to solve the
troublesome cleaning process.
I felt so thankfully that my friend gave me lots of
ready washed and cleaned dried fish scales for my
blog writing and making healthy dessert. As when I
tried to cook for a few times, I found it is nice for
what was at first I thought fish scales should be
fishy smelly odor in taste but not. With the
preparation and added some pandanus leaves to
it. It just tastes like pandan Jelly. Nice taste and
not that bad.

Although drinking collagen-rich soup or making
jelly from the natural source of fish scales may not
be easily absorb into human body, due to the
human digestive system is the main filter out a
large part, and how much the fish scales collagen
and its micro-nutrients can really reach the human
body, and skin in absorption is very limited,
therefore, the process of benefit is relatively
lengthy, the efficiency is low, still daily
consumption may help too.
Thus, Collagen extracted in smallest molecules to
the human body needs the degradation of collagen
peptide molecular, and amino acids then only can
be absorbed by the body. However, Collagen
peptides, collagen molecules into the human body
needs obtaining from fish scale containing peptidesequence of the protein is more comprehensive,
more nutrition and the affinity of the human body.
Anyway, no harm give it a try, fish scales is the
cheapest to get it from fishery.

Grow Your Own The Hydroponics System
Have you ever thought about growing your own
vegetables, but found that owning a landed
property just to build raised beds a little too
expensive? Or do you find yourself squirming at
the thoughts of putting your hands into bucket
loads of muck and soil? Well, if you have, then
hydroponics is the solution for you.
In the course of the next few weeks, we will look
into a number of soilless food growing methods,
and how you can build one of your own. In this
issue, we will cover hydroponic systems.
The Hydroponic Systems
There are six basic types of hydroponic systems,
each with hundreds of variations and
combinations. These hydroponic systems are fairly
simple in concept, and once you understand how
the systems work, building your own wont be hard
and can even be fun.
(i) Water Culture or Floating Raft System
The water culture, or more commonly termed
floating raft system, is the simplest of all active
hydroponic system. A platform that holds the
plants made of Styrofoam float directly above the
nutrient solution. An air pump supplies air through
the air stone, and the bubbles circulate the nutrient
solution and oxygen to the roots of the plants. A
simple depiction of the system is as follows:
Figure 1: Floating Raft System Source: www.homehydrosystems.com
Crops most often grown using this system are fast
growing plant which have high water uptakes,
such as lettuce or cabbage. Very few plants other
than these two will do well in this type of system.
(ii) Wick System
The wick system is a simple hydroponic system
with contains no moving parts. All there is to it is
the use of a wick which draws nutrient solution into
the growing medium from a reservoir. The growing
medium used usually loose materials absorbent
materials such as perlite, sphagnum moss, or
cocopeat.
Figure 2: Wick System Source: www.hydro-heaven.com
(iii) The Drip System
The drip system is the most widely used type of
hydroponic system, with a simple timer-controlled
operation and a submersed pump. A depiction of
the drip system is as follows:

is dripped onto the base of each plant by a small
drip line. The excess nutrient solution that runs off
is collected back in the reservoir for re-use. The
growth media normally used are loose perlite or
other similar light-weight materials such as
cocopeat, expanded clay, and lava rocks.
(iv) Nutrient Film Technique (NFT) System
The NFT system is one of the more
commercialized versions of hydroponics. This
system employs a constant flow of nutrient
solution, and thus, no timer is required to control
the submersible pump. The nutrient solution which
is pumped through the growth tray (normally a
PVC tube) flows over the roots of the plant, and
drains back into the reservoir. A depiction of this
system is as follows:

There is usually no growing medium used other
than air; the plants are supported by small plastic
baskets with roots dangling. Though efficient, NFT
systems are very susceptible to power outages
and pump failures, which result in plant roots
drying out very rapidly when the flow of nutrient
solution is interrupted.
(v) Flood and Drain System
The flood and drain system works by attaching a
timer to a submersible pump which periodically
activates to temporarily flood the grow tray with
nutrient solution, and then drain it back into the
reservoir. As with the NFT system, it is susceptible
to power outages and cycle disruptions. A
depiction of this system is as follows:

(vi) Aeroponic System
The most high-tech type of hydroponic system, the
aeroponic system uses air as the growing medium.
Roots hang out in the air, and are misted with
nutrient solution every few minutes. Like the NFT
system, the roots are exposed and are thus highly
vulnerable to power outages and cycle
interruptions.

The good thing about the aeroponic system is that
it maximizes use of small spaces when placed in
vertical form.
There are many ways to design a workinghydroponics system using commonly found
materials from home improvement. In the next
issue, we will focus on how to construct a simple
hydroponic system using recycled materials.
