Maximizing the Growth of Sawi Samhong with Tofu Waste POC in the Wick Hydroponic System

The use of organic fertilizers has become increasingly popular in recent years due to their environmental benefits and potential to improve crop yields. One such organic fertilizer is liquid organic fertilizer (POC) derived from tofu waste, which has been shown to have a positive impact on plant growth. This article discusses a study conducted at the Aceh Tamiang Hydroponic Management Management Center, Aceh, in October to December 2021, which aimed to determine the growth and production response of Sawi Samhong (Brassica Juncea L.) to the nutrition of Tofu Waste POC in the Wick Hydroponic System.

Background and Objectives

Sawi Samhong is a popular leafy green vegetable in many parts of the world, known for its nutritional value and versatility in cooking. However, its cultivation often relies on synthetic fertilizers, which can have negative environmental impacts. The use of organic fertilizers like Tofu Waste POC offers a more sustainable alternative. This study aimed to investigate the effect of Tofu Waste POC on the growth and production of Sawi Samhong in the Wick Hydroponic System.

Methodology

The study used a complete random design (RAL) with five concentrations of Tofu Waste POC: 0%, 5%, 10%, 15%, and 20%. The experiment was conducted over a period of 5 weeks, with measurements taken on plant height, number of leaves, wet weight, dry weight, chlorophyll A, chlorophyll B, and total leaf chlorophyll, and relative growth rates.

Results

The results showed that Tofu Waste POC had a significant effect on plant height and the number of Samhong mustard leaves in the second to fifth week after treatment. The 20% POC concentration produced the highest plant height (24.14 cm), the highest number of leaves (6.80), the highest wet weight (80.73 g), and the highest dry weight (9.02 g). However, Tofu Waste POC did not have a significant effect on chlorophyll A, chlorophyll B, and total leaf chlorophyll, and relative growth rates in the first to fifth week after treatment.

Discussion

The study found that Tofu Waste POC is rich in nutritional nutrients for plants, such as nitrogen, phosphorus, and potassium, which helps the vegetative growth of plants, including plant height and number of leaves. However, a decrease in chlorophyll levels can be caused by several factors, including high organic substances, nutrition availability, and phytohormone content.

Why did the Tofu Waste POC affect the growth of Sawi Samhong?

Tofu waste POC is rich in nutritional nutrients for plants, such as nitrogen, phosphorus, and potassium. This nutritional content helps the vegetative growth of plants, including plant height and number of leaves. However, a decrease in chlorophyll levels can be caused by several factors, such as:

High Organic Substances: Tofu Waste POC contains high organic substances, which can cause changes in soil pH or nutritional solutions.
Nutrition Availability: Nutrition in Tofu Waste POC may not be entirely available for plants, resulting in competition between microorganisms and plants in absorbing nutrients.
*Fitohormone Content: Tofu Waste POC also contains phytohormone, which can affect the physiological processes of plants, including chlorophyll formation.

Conclusions and Recommendations

This study proves the potential of Tofu Waste POC as organic fertilizer to increase the growth of Sawi Samhong in the Wick hydroponic system. The 20% POC concentration produces optimal growth and production of mustard greens. However, further research needs to be done to determine the effect of Tofu Waste POC on nutritional quality and Phytochemical content of Sawi Samhong.

Utilization of Tofu Waste POC in Samhong Sawi Cultivation

Utilization of Tofu Waste POC in Samhong Sawi cultivation provides several benefits, including:

*Increasing fertilizer efficiency: Tofu waste POC utilizes organic waste that is usually discarded, so that it is more environmentally friendly and economically efficient.
*Improving product quality: SAWI SAMHONG which is planted with POC Tofu Waste has the potential to produce higher quality products, both in terms of nutrition and organoleptic.
*Producing organic products: Tofu waste POC can be used to produce organic samhong sawi products, which are increasingly in demand by consumers.

Thus, this research provides a strong basis for the development of organic Samhong Sawi cultivation using Tofu Waste POC.

Future Directions

Further research is needed to determine the effect of Tofu Waste POC on nutritional quality and Phytochemical content of Sawi Samhong. Additionally, the study of the optimal concentration of Tofu Waste POC for different types of crops and the development of a more efficient method for producing Tofu Waste POC are also necessary.

Conclusion

In conclusion, this study demonstrates the potential of Tofu Waste POC as an organic fertilizer to increase the growth of Sawi Samhong in the Wick hydroponic system. The results of this study provide a strong basis for the development of organic Samhong Sawi cultivation using Tofu Waste POC, which can contribute to a more sustainable and environmentally friendly agricultural practice.
