MENANAM & PANEN Sawi Caisim dan Pelihara Ikan Lele Aquaponik Drum Di Kebun Halaman Rumah

Summary

This video showcases the process of growing mustard greens (sawi caisim) in an aquaponic drum system. The presenter demonstrates the steps from preparing the planting area, germinating seeds in rockwool, transplanting seedlings into the system, to caring for the plants with nutrients from tilapia waste. Over a 32-day period, the mustard greens grow healthily, even after showing initial yellowing. The system also supports fish farming, with tilapia being fed and eventually harvested. The video provides an informative guide for beginners interested in sustainable gardening through aquaponics.

Takeaways

• 😀 The video demonstrates how to grow caisim (Chinese mustard) in an aquaponic system using a fish drum previously used for growing water spinach.
• 😀 After harvesting the previous crop, the system is cleaned by removing leftover plants and roots, and the growing media is rinsed.
• 😀 Rockwool is used for seedling propagation, with one seed per hole to ensure efficient growth of the caisim.
• 😀 The seedlings are watered with regular tap water, and the rockwool is kept moist but not waterlogged during germination.
• 😀 The seeds are stored in a dry place until they sprout, usually within 1-2 days, before being moved to the planting area.
• 😀 Caisim seedlings are planted in a system using gravel and broken tiles as growing media, ensuring proper spacing for optimal growth.
• 😀 The video explains that the seedlings were initially yellow but will improve once they receive nutrients from the aquaponic system.
• 😀 Fish feeding is done twice a day with pellets, and sometimes maggots or insects are added to the diet to supplement the nutrition.
• 😀 Aquaponic system water is never drained but topped up when it evaporates or is absorbed by the plants.
• 😀 The caisim reaches harvestable size in about 32 days after planting, and the video demonstrates the harvesting process for both the vegetables and the fish.
• 😀 The fish (catfish) are harvested when they are large enough, and the video concludes with a simple cooking demonstration of the fish.

Q & A

What type of plant is being grown in the aquaponic system?

The plant being grown is mustard greens (Sawi Caisim), which is a leafy vegetable commonly used in Indonesian cuisine.

Why was the previous crop (water spinach) replaced with mustard greens?

The previous crop, water spinach (kangkung), was harvested, and the grower decided to replace it with mustard greens for the next cycle of planting.

What preparation steps are taken before planting new seeds?

Before planting new seeds, the grower cleans the planting area by removing old plant remnants and any leftover roots, ensuring the growing medium, such as the gravel, is ready for the new crop.

How are mustard green seeds sown in the aquaponic system?

Mustard green seeds are sown in small holes made in rockwool. Each hole contains one seed to ensure optimal growth, as the plant tends to spread sideways.

What care is provided to the mustard green seeds during the germination process?

The seeds are watered regularly to keep the rockwool moist, but care is taken to avoid waterlogging. The germinating seeds are placed in a warm, dry area until they sprout.

How is the aquaponic system maintained during the seedling stage?

During the seedling stage, the grower waters the plants only when the growing medium starts to dry out. The water used for irrigation is regular tap water.

What nutrients do the mustard greens receive during their growth?

The mustard greens receive nutrients primarily from the waste produced by the fish in the aquaponic system, which acts as a natural fertilizer.

What is the typical timeline for mustard greens to be ready for harvest in the system?

Mustard greens typically take 32 days from planting to reach harvest size in the aquaponic system.

What challenges did the mustard greens face during the early stages of growth?

Initially, the mustard greens showed some yellowing of the leaves, which is common when plants haven't received fertilizers. However, this resolved as the fish provided more nutrients over time.

How is the fish care managed in the aquaponic system?

The fish (catfish) are fed twice daily, with a mix of pellet feed and, occasionally, maggots or insects like grasshoppers. The water in the drum is topped up when it decreases due to absorption by the plants or evaporation.

How does the aquaponic system impact the health of the fish?

The fish remain healthy as they are fed regularly, and the system's water quality is maintained by the plants. The fish waste provides essential nutrients for the plants, creating a balanced ecosystem.

What happens when it's time to harvest the mustard greens?

When the mustard greens are ready for harvest, they are carefully uprooted, and the roots are gently removed from the gravel. The harvested greens are then prepared for consumption.
