The Effect of Free Fatty Acids (ALB) on the Quality Standards of Crude Palm Oil (CPO) at PTPN III PKS Aek Nabara Selatan Unit

Introduction

The quality of crude palm oil (CPO) is a critical factor in determining its market value and consumer acceptance. One of the key parameters that affect the quality of CPO is the level of free fatty acids (ALB). The determination of ALB levels is essential to ensure that the resulting oil meets the established quality standards. In this article, we will discuss the effect of ALB on the quality standards of CPO at PTPN III PKS Aek Nabara Selatan Unit.

The Importance of Free Fatty Acids (ALB) in CPO

Free fatty acids (ALB) are a type of fatty acid that is present in CPO. The level of ALB in CPO is a critical factor in determining its quality. High levels of ALB can affect the processing, final product quality, and CPO shelf life. The higher the ALB level, the greater the potential for oxidation reactions that can cause rancidity and decreased oil quality.

Measurement of Free Fatty Acid Levels

Measurement of free fatty acid levels is very crucial in the palm oil processing industry, especially to ensure that the resulting oil meets the established quality standards. The determination of ALB levels is usually carried out using the alkalimetric titration method, which is included in the category of acid-base titration. This method is widely used in the palm oil industry due to its accuracy and reliability.

Analysis of ALB Levels at PTPN III PKS Aek Nabara Selatan Unit

A study was conducted at PTPN III PKS Aek Nabara Selatan Unit to determine the level of ALB in CPO. The analysis was carried out in the period 4 to 9 February 2017, and the results showed ALB levels ranging from 4.67% to 5.39% for CPO stored in a tank at 50 ° C to 55 ° C. Based on the Indonesian National Standard (SNI), ALB levels must be less than 5.00%.

The Impact of Storage Temperature on ALB Levels

The storage temperature factor also plays an important role in ALB's stability. Storage temperatures that are too high can accelerate the formation of ALB, so it is essential to maintain the temperature of the storage tank within a safe limit. In this study, the storage temperature ranges from 50 ° C to 55 ° C, which must be monitored periodically to prevent an unwanted increase in ALB levels.

The Role of Quality Control in Maintaining ALB Levels

Therefore, serious attention to the ALB content and the factors that influence it is very necessary to maintain the quality of CPO. Appropriate handling can increase product competitiveness in the market and meet consumer expectations of good quality palm oil quality. Thus, the factory manager must implement strict quality control and supervision of the process so that all parameters, including free fatty acid levels, remain within the desired limits.

Conclusion

In conclusion, the level of free fatty acids (ALB) is a critical factor in determining the quality of crude palm oil (CPO). The determination of ALB levels is essential to ensure that the resulting oil meets the established quality standards. The storage temperature factor also plays an important role in ALB's stability, and it is essential to maintain the temperature of the storage tank within a safe limit. Therefore, serious attention to the ALB content and the factors that influence it is very necessary to maintain the quality of CPO.

Recommendations

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

The factory manager must implement strict quality control and supervision of the process to ensure that all parameters, including free fatty acid levels, remain within the desired limits.
The storage temperature must be monitored periodically to prevent an unwanted increase in ALB levels.
The level of ALB in CPO must be determined regularly to ensure that it meets the established quality standards.

Future Research Directions

Future research directions include:

Investigating the effect of storage temperature on ALB levels in different types of palm oil.
Developing a new method for determining ALB levels that is more accurate and reliable.
Investigating the impact of ALB levels on the shelf life of CPO.
