The Study of the Use of Fish Waste from Fish Auction Places (TPI) and Sibolga Traditional Markets as Raw Materials for Compost

Introduction

Sibolga, a city renowned for its seafood, generates a substantial amount of fish waste from fish auction places (TPI) and traditional markets. For a long time, this waste has been considered a problem, but it turns out to hold great potential to be processed into high-quality compost. A study has successfully demonstrated that fish waste can be converted into organic fertilizer rich in nutrients and environmentally friendly. This article will delve into the study's findings and explore the benefits of utilizing fish waste as a raw material for compost.

The Composting Process

The study employed composting methods with the aid of EM4, microorganisms activated with sugar cane drops. The composting process lasted for 20 days, with strict supervision of temperature, color, and odor. Regular compost reversal was done to maintain optimal temperature levels. This meticulous approach ensured the production of high-quality compost.

The Results

The analysis of the compost on days 0, 2, 5, 10, 15, and 20 revealed impressive results. The resulting compost had C-organic levels reaching 51.69%, Nitrogen 8.25%, Posfor 4.75%, and Potassium 1.56 %. These nutritional levels exceeded the SNI compost standards, indicating that compost from fish waste has great potential to fertilize the soil and increase yields.

Why Does Fish Waste Become Good Fertilizer?

Fish waste is rich in nutrients essential for plant growth, particularly nitrogen, phosphorus, and potassium. Additionally, fish waste contains organic substances that can improve soil structure, making it more loose and increasing water absorption. These characteristics make fish waste an ideal raw material for compost.

Benefits of Compost from Fish Waste

The benefits of compost from fish waste are numerous:

Increasing Soil Fertility: Nutrition-rich compost can increase soil fertility and help plants grow healthier. Improving Soil Structure: Compost makes the soil more loose, allowing plant roots to grow more freely and absorb water and nutrients better. Eliminating Pests and Diseases: Compost can increase the population of beneficial soil microorganisms, suppressing the population of pathogenic microorganisms that cause plant diseases. Environmentally Friendly: Fish waste treatment into compost is an environmentally friendly solution, reducing environmental pollution and minimizing waste disposal to a landfill.

Utilization of Fish Waste Compost in Sibolga

This research opens up great opportunities for the Sibolga community to utilize fish waste as a source of organic fertilizer. Fishermen, fish traders, and farmers can work together in processing fish waste into compost. The use of this compost will increase yields, reduce the cost of chemical fertilizers, and ultimately improve the welfare of the Sibolga community.

Conclusion

The study's findings demonstrate the potential of fish waste as a raw material for compost. The compost produced from fish waste has high nutritional levels, making it an ideal fertilizer for soil. The utilization of fish waste compost in Sibolga can have a positive impact on the community, increasing yields and reducing environmental pollution. The next step is to disseminate the knowledge and technology of making compost from fish waste to the Sibolga community, ensuring the success of this program and converting the great potential of fish waste into resources beneficial to the environment and the Sibolga community.

Recommendations

To ensure the success of this program, the following recommendations are made:

Training and assistance should be provided to fishermen, fish traders, and farmers to ensure they understand the composting process and can produce high-quality compost.
The Sibolga community should be educated on the benefits of using compost from fish waste as a fertilizer, and the importance of reducing environmental pollution.
The government and local authorities should provide support and resources to help establish a composting program in Sibolga, ensuring the success of this initiative.

By following these recommendations, the Sibolga community can harness the potential of fish waste and create a more sustainable and environmentally friendly future.
Frequently Asked Questions (FAQs) About Composting Fish Waste

Q: What is composting, and how does it work?

A: Composting is the process of breaking down organic materials, such as fish waste, into a nutrient-rich fertilizer. Microorganisms, like bacteria and fungi, feed on the organic matter, releasing carbon dioxide, water, and heat in the process. The resulting compost is a valuable resource for improving soil health and fertility.

Q: Why is fish waste a good candidate for composting?

A: Fish waste is rich in nutrients, such as nitrogen, phosphorus, and potassium, which are essential for plant growth. Additionally, fish waste contains organic substances that can improve soil structure, making it more loose and increasing water absorption.

Q: What are the benefits of using compost from fish waste?

A: The benefits of using compost from fish waste include:

Increasing soil fertility and plant growth
Improving soil structure and water absorption
Eliminating pests and diseases
Reducing environmental pollution and waste disposal to landfills
Providing a sustainable and environmentally friendly fertilizer option

Q: How long does the composting process take?

A: The composting process typically takes 20-30 days, depending on factors such as temperature, moisture, and the type of microorganisms used.

Q: What are the ideal conditions for composting fish waste?

A: The ideal conditions for composting fish waste include:

Temperature: 50-60°C (122-140°F)
Moisture: 50-60%
pH: 6.0-7.0
Aeration: Regular turning and mixing of the compost pile

Q: Can I compost fish waste at home?
