Control of Biologically Palm Oil Factory Liquid Waste and Its Effects Facing Soil Properties, Glycine Max Growth (Glycine Max)

Introduction

The palm oil and rubber plantation industry is one of the largest producers of waste in the world. The management of this waste is a serious concern, as it can have significant impacts on the environment. Among the various types of waste produced by palm oil mills, Liquid Waste of Palm Oil Mill (LCPKS) is a major focus due to its substantial impact on the environment. In this article, we will discuss the control of biologically palm oil factory liquid waste and its effects on soil properties and Glycine Max plant growth.

The Problem of Liquid Waste in Palm Oil Mills

Palm oil mills produce a significant amount of waste, with around 45-50% of the processed fresh fruit bunches (FFB) becoming waste. This waste is generated from the processing of FFB into palm oil, and it is estimated that 50-60 tons of water and other materials are used in the process. The liquid waste produced by palm oil mills is a major concern, as it can pollute waterways and soil if not managed properly.

Biological Liquid Waste Control

Biological wastewater control is an increasingly popular method for reducing pollution and negative impacts on the environment. In the context of LCPKS, this process involves the use of microorganisms to decompose organic matter in liquid waste. This method not only reduces the volume of waste but also changes it to compost, which can be beneficial for soil fertility. The use of biological processing technology, such as depositional ponds and bioreactor reactors, has been proven effective in reducing BOD levels (Biochemical Oxygen Demand) and COD (Chemical Oxygen Demand) in liquid waste.

The Effect of Biological Liquid Waste Control on Soil Properties

The processing of LCPKS biologically has a significant influence on the physical and chemical properties of the soil. The application of liquid waste that has been well decomposed in the soil can increase the content of organic matter, which in turn increases the ability of the soil in storing water and nutrients. The use of well-managed liquid waste also has the potential to restore soil fertility lost due to conventional agricultural practices.

Ultisol soil, which is one type of soil that is often found in the tropics, has a characteristic that tends to be acidic and low fertility. The application of LCPKS that is processed biologically can increase soil pH and important nutritional content such as nitrogen, phosphorus, and potassium, thus making it more fertile.

The Effect of Biological Liquid Waste Control on Glycine Max Plant Growth

One plant that can be used as an indicator of soil fertility is soybean (glycine max). The growth of soybean plants can be directly influenced by LCPKS management. With the increase in soil fertility thanks to the application of liquid waste that has been biologically processed, the growth and yield of soybean plants can increase significantly.

Research shows that soybean plants planted in land enriched with LCPKS tend to have better growth compared to plants planted in the soil without liquid waste treatment. Growth parameters, such as plant height, number of branches, and soybean seed weight, can increase along with the improvement of soil quality due to the use of LCPKS.

Conclusion

Control of biological oil palm factory liquid waste not only helps reduce the negative impact on the environment, but also brings positive benefits to soil fertility and plant growth, especially soybean (glycine max) in ultisol soils. By applying the right processing method, we can convert waste into valuable resources, support sustainable agriculture, and maintain the balance of ecosystems. Therefore, greater attention to the management of LCPKS must continue to be encouraged for the sustainability of the palm oil industry and environmental protection.

Development of Biological Liquid Waste Control Technology: The development of biological liquid waste control technology should be continued to improve its effectiveness and efficiency.
Implementation of LCPKS Management: The implementation of LCPKS management should be encouraged to reduce the negative impact of LCPKS on the environment.

By following these recommendations and future research directions, we can ensure the sustainability of the palm oil industry and environmental protection.
Frequently Asked Questions (FAQs) about Control of Biologically Palm Oil Factory Liquid Waste and Its Effects on Soil Properties and Glycine Max Plant Growth

Q: What is Liquid Waste of Palm Oil Mill (LCPKS)?

A: LCPKS is a type of waste produced by palm oil mills during the processing of fresh fruit bunches (FFB) into palm oil. It is estimated that around 45-50% of the processed FFB becomes waste, along with 50-60 tons of water and other materials used in the process.

Q: Why is LCPKS a concern?

A: LCPKS is a concern because it can pollute waterways and soil if not managed properly. The liquid waste can contain high levels of biochemical oxygen demand (BOD) and chemical oxygen demand (COD), which can harm aquatic life and soil microorganisms.

Q: What is biological liquid waste control?

A: Biological liquid waste control is a method of reducing pollution and negative impacts on the environment by using microorganisms to decompose organic matter in liquid waste.
