Utilization of Kepok Yellow Banana Skin (Musa paradisiaca var. Bluggoe) as a Liquid Organic Fertilizer for the Growth of Pagoda Mustard Greens (Brassica Rapa var. Narinosa L.)

Introduction

In recent years, the world has witnessed a growing concern about the environmental impact of chemical fertilizers used in agriculture. The excessive use of these fertilizers has led to soil degradation, water pollution, and loss of biodiversity. As a result, there is a pressing need to explore alternative and sustainable methods of fertilization. One such approach is the utilization of organic waste materials as liquid organic fertilizers. This study aims to investigate the potential of using Kepok yellow banana peels as a liquid organic fertilizer for the growth of Pagoda mustard greens.

Background

Kepok yellow banana peels, a by-product of the banana industry, are often discarded as waste. However, these peels are rich in nutrients, including nitrogen, phosphorus, and potassium, which are essential for plant growth. The fermentation process using EM4 (Effective Microorganisms) can enhance the availability of these nutrients, making the peels a potential source of liquid organic fertilizer.

Methodology

This study employed a non-factorial complete random design (CRD) with seven treatments. Four treatments consisted of POC (Processed Organic Compound) applications with concentrations of 25%, 50%, 75%, and 100%, as well as a treatment without fertilizer. Two additional treatments used NPK fertilizer (16:16:16) and EM4 as a comparison. The observed growth parameters included plant height, number of leaves, wet weight, dry weight, root to stem ratios, as well as chlorophyll and fiber content.

Results

The analysis of the POC from Kepok yellow banana peels revealed a C-organic content of 1.27%, N-total of 0.13%, P of 7.14%, and pH of 4.86. The results showed that POC with a concentration of 100% significantly had a positive effect on all pagoda mustard green parameters, except for the ratio of roots to stem and fiber content. Furthermore, variations in POC concentrations higher than 25% gave better results than the control and EM4, although they were still lower than the treatment with NPK fertilizer.

Discussion

The use of banana peels as liquid organic fertilizer is a promising approach to reducing agricultural waste and promoting sustainable agriculture. The fermentation process with EM4 not only increases the availability of nutrients in POC but also improves soil pH, contributing to increased plant growth. The measured NPK content in POC indicates that yellow kepok banana peels are rich in phosphorus, which plays a crucial role in root growth and plant development. This supports the need for the growth of Pagoda mustard greens, which requires sufficient nutrition for optimal growth.

Conclusion

The results of this study demonstrate the potential of using Kepok yellow banana peels as a liquid organic fertilizer for the growth of Pagoda mustard greens. The use of POC with a concentration of 100% showed a positive impact on growth, indicating the importance of finding the ideal fertilization dose. Excessive concentration of fertilizer can cause phytotoxic effects, making it essential for farmers to find the optimal concentration. The utilization of yellow kepok banana peels as liquid organic fertilizer not only benefits plant growth but also contributes to reducing waste and increasing soil fertility, aligning with the concept of sustainable agriculture.

Recommendations

Based on the findings of this study, the following recommendations are made:

Further research: Conduct further research to explore the potential of using Kepok yellow banana peels as a liquid organic fertilizer for other crops.
Optimization of POC concentration: Optimize the concentration of POC to find the ideal dose for maximum plant growth.
Scalability: Scale up the production of POC to make it a viable alternative to chemical fertilizers.
Education and awareness: Educate farmers and the general public about the benefits of using liquid organic fertilizers and the importance of sustainable agriculture.

Limitations

This study has several limitations, including:

Small sample size: The study had a small sample size, which may limit the generalizability of the results.
Limited crop selection: The study only investigated the use of POC for Pagoda mustard greens, and further research is needed to explore its potential for other crops.
Lack of control group: The study did not include a control group without any fertilizer, which may have affected the results.

Future Directions

Future research should focus on:

Exploring the potential of POC for other crops: Investigate the use of POC for other crops to determine its potential as a liquid organic fertilizer.
Optimizing POC production: Optimize the production of POC to make it a viable alternative to chemical fertilizers.
Scalability and commercialization: Scale up the production of POC and explore its commercialization potential.

By addressing these limitations and exploring new avenues, this study can contribute to the development of sustainable agriculture practices and reduce the environmental impact of chemical fertilizers.
