Cara menanam kangkung hidroponik dalam pot.

Summary

In this tutorial, Weti Yuningsih demonstrates how to grow water spinach (kangkung) using a hydroponic method, designed for senior high school science students. She explains the materials needed, including a basin, fabric, scissors, markers, and water spinach seeds. The process involves cutting fabric to fit the basin, placing it in the basin, adding water, and sowing the seeds. To promote faster germination, the seeds are kept in a dark environment, shielded from sunlight. The tutorial aims to help students learn about seed germination and plant growth in a hydroponic setup, culminating in a practical assignment for them to report on.

Takeaways

• 😀 The tutorial is designed for 12th-grade science and social studies students to learn about hydroponic kangkung planting.
• 😀 The key materials needed include a basin, a basket with holes, flannel fabric or tissue, scissors, a marker, kangkung seeds, and water.
• 😀 The basin should be without holes, ensuring water stays inside when setting up the hydroponic system.
• 😀 Flannel fabric is cut to fit the bottom of the basin, serving as the medium for seed germination.
• 😀 The basket, placed in the basin, holds the seeds and ensures they have access to water through the fabric.
• 😀 Seeds should be spaced out properly to allow enough room for growth and prevent overcrowding.
• 😀 Water is added to the basin, but it should only reach just below the flannel fabric, not too much to prevent oversaturation.
• 😀 After planting, the seeds are lightly watered to ensure they stay hydrated.
• 😀 To speed up germination, the seeds should be kept in a dark environment, covered with dark plastic to block light.
• 😀 The dark environment helps the seeds germinate faster because of the influence of auxin, a hormone that thrives in darkness.
• 😀 The tutorial concludes by encouraging students to report their results after completing the experiment, promoting practical engagement and learning.

Q & A

What is the main topic of the tutorial?

The main topic of the tutorial is how to grow kangkung (water spinach) hydroponically, aimed at students in class 12 IPA and 12 IPS for a practical exercise on seed germination and growth.

What tools and materials are required for the hydroponic kangkung planting?

The required tools and materials include a basin (without holes), a perforated basin for placing the kangkung, flannel or tissue, scissors, a marker, kangkung seeds, and plain water.

Why is it important for the basin to not have holes?

The basin should not have holes to prevent water from leaking out when it's filled. This ensures the water stays in the basin and creates a proper environment for the seeds to germinate.

What is the purpose of the flannel or tissue in the hydroponic setup?

The flannel or tissue serves as a medium to hold the kangkung seeds and allow them to absorb water, helping with seed germination.

How should the flannel be prepared for the hydroponic planting?

The flannel should be cut into a shape that fits the bottom of the basin. It needs to cover the base to provide a stable platform for the seeds to grow on.

What should be done after placing the flannel in the basin?

After placing the flannel in the basin, you should add water until it reaches just below the level of the flannel. Be careful not to overfill the basin to avoid water spillage.

How should the kangkung seeds be placed in the hydroponic setup?

The kangkung seeds should be scattered evenly over the flannel, but not too densely. It's important to leave enough space between the seeds to allow for proper growth.

Why is it necessary to cover the seeds with dark plastic?

The seeds need to be kept in the dark for the germination process to proceed quickly. Darkness helps the seeds develop faster by preventing light from affecting the growth hormone auxin, which prefers a dark environment.

How does light affect the germination of kangkung seeds?

Light affects the germination of kangkung seeds because the hormone auxin, which regulates plant growth, prefers darkness. Exposure to light can slow down or hinder the germination process.

What should be done after setting up the hydroponic kangkung setup?

After setting up the hydroponic setup, the next step is to wait for a day to check if the seeds have started germinating. The setup should be monitored regularly to ensure optimal conditions for seed growth.
