Budikdamber, is an engineering media of fish culture in a bucket combined with the method of growing food vegetables with aquaphonic techniques,

This method was initiated by Juli Nursadi, S. Pi., M. Si. Lecturer at POLITEKNIK NEGERI LAMPUNG, INDONESIA

And the spreading of information was developed through social media communication and online groups by some activists as did Sutan M Rizky Tizar, and other activists.

Why cultivate fish in a bucket can be explained through two sides namely,

Threats: Limited land for fish cultivation, good quality and quantity of water for fish farming is increasingly limited.

Opportunities: The need for animal protein from fisheries and vegetables continues to increase as the population grows.

One example of the application of this budikdamber media engineering is the cultivation of catfish and kale in one bucket.

Materials needed to make the buddamer technique is

1. 80 Liter Bucket

2. Coconut Shell Charcoal

3. Plastic Cups

4. Catfish Seed

5. Pliers

6. Wire

7. Water spinach seeds

8. Electric Soldering

The manufacturing steps start from

Preparation of glass and water spinach

1. Punch 10-15 plastic cups using Electric Solder / its replacement.

2. Cut the water spinach and leave the roots.

3. Put the roots of spinach into a plastic cup.

4. Put the charcoal into a plastic glass 50% - 80% the size of the glass.

5. Cut the wire (12cm) and make a hook to hold the plastic cup in the bucket.

Fish Seed (Catfish)

seed size: 5-12cm

number of 60-100 tails

Media Preparation

1. Fill 60 liters of water and set aside 1-2 days.

2. Enter the fish let stand 1-2 days.

3. Arrange the spinach glass on the lip of the bucket.

Maintenance

The bucket is placed where it is exposed to maximum sunlight.

Water spinach will be seen growing on day 3.

If there are lice in kale, immediately remove the leaves or stems, because the kale will curl and die.

Give food to fish, in accordance with the size of it, can be 2-3 times with a fixed time. (5-7cm pf800 feed, 10cm pf1000,> 12cm 781 -2, 781 -1, 781).

The water turns green, observe the fish's appetite.

Water / Sipon replacement

When

1. Fish appetite decreases.

2. The water is foul smelling (NH3, H2S).

3. Hang fish (head above, tail down).

Replace water or Sipon (desludging from the bottom of the bucket with a hose) usually once every 10-14 days.

Suction 5-8 liters, can be more or whole if necessary,

Replace water with clean water,

Enlarged spinach requires more water, add water up to the neck of the bucket.

Harvest

The first kale harvest is 14-21 days since planting,

Leave the bottom - kale buds for regrowth.

The second and subsequent harvests are 10-14 days apart.

Can last up to 4 months.

Catfish harvest can be done in 2 months, if the seeds are good and the feed is good.

Survival rate is 40 - 100%.

Done with scoop or in the drain.

Fish are reduced by jumping when it rains, cannibals, or being eaten by cats.
