Analysis of Impurities in Crude Palm Oil: Impact of Hoarding Time at PT. AGRO NUSANTARA UNIT BELAWAN FACILITIES

Introduction

Crude palm oil (CPO) is a major commodity in the global market, and its quality is crucial for the production of various food and non-food products. However, the presence of impurities in CPO can significantly reduce its quality and affect its market value. PT. AGRO NUSANTARA UNIT BELAWAN FACILITIES, a leading palm oil producer, has been concerned about the accumulation of impurities in their storage tubs. This study aims to analyze the impact of hoarding time on the accumulation of impurities in CPO at PT. AGRO NUSANTARA UNIT BELAWAN FACILITIES.

Background

Crude palm oil is a complex mixture of triglycerides, free fatty acids, and other impurities. The presence of impurities in CPO can be attributed to various factors, including the quality of raw palm oil, shelter conditions, temperature and humidity, and hoarding time. The Indonesian National Standards (SNI) sets the maximum limit of impurities in CPO at 0.027%. However, exceeding this limit can result in significant economic losses and damage to the reputation of the company.

Methodology

This study employed a gravimetric method to determine the levels of impurities in CPO at PT. AGRO NUSANTARA UNIT BELAWAN FACILITIES. The analysis was conducted on five consecutive days, with the first day representing the initial level of impurities and the subsequent days representing the accumulation of impurities over time.

Results

The results of the analysis showed that the levels of impurities on the first day of hoarding were 0.024%, the second day 0.025%, the third day 0.025%, the fourth day 0.024%, and the fifth day 0.026%. These results indicate that variations in impurities during the accumulation time still meet the Indonesian National Standards (SNI) which sets the maximum limit of impurities in CPO at 0.027%.

Factors that Affect Impurities Levels

Several factors can affect the levels of impurities in CPO during hoarding, including:

Early Raw Palm Oil Quality

Raw palm oil that has been polluted since the beginning of the production process will have higher levels of impurities. This is because the quality of raw palm oil is directly related to the level of impurities present in the final product.

Shelter Conditions

The condition of the reservoir that is less hygienic, such as the presence of dirt, water, or fungus, can increase levels of impurities. This is because the presence of contaminants in the reservoir can lead to the growth of microorganisms, which can contribute to the accumulation of impurities in CPO.

Temperature and Humidity

High temperature and humidity can accelerate the oxidation and hydrolysis process, which in turn can increase levels of impurities. This is because high temperatures and humidity can lead to the breakdown of triglycerides and the formation of free fatty acids, which can contribute to the accumulation of impurities in CPO.

Long Hoarding

The longer the accumulation time, the higher the potential for oxidation and hydrolysis, which can increase levels of impurities. This is because the longer the CPO is stored, the more time there is for the breakdown of triglycerides and the formation of free fatty acids.

Recommendations for Reducing Impurities Levels

To reduce levels of impurities in CPO during hoarding, the following recommendations can be implemented:

Improving the Quality of Early Crude Palm Oil

Improving the production process, such as the use of hygienic tools and strict supervision, can produce cleaner CPO and minimal impurities. This is because the quality of raw palm oil is directly related to the level of impurities present in the final product.

Maintaining Hygienic Shelter Conditions

Routine cleaning and maintenance in the reservoir is very important to prevent the entry of dirt, water, and mushrooms. This is because the presence of contaminants in the reservoir can lead to the growth of microorganisms, which can contribute to the accumulation of impurities in CPO.

Temperature and Humidity Control

Temperature and humidity in the reservoir must be maintained so that it remains stable. The use of cooling and drying systems can help in controlling temperatures and humidity. This is because high temperatures and humidity can accelerate the oxidation and hydrolysis process, which can increase levels of impurities.

Minimizing the Time of Hoarding

The process of processing CPO should be done as soon as possible after harvest to minimize the time of hoarding. This is because the longer the CPO is stored, the more time there is for the breakdown of triglycerides and the formation of free fatty acids.

Conclusion

The accumulation of impurities in CPO at PT. AGRO NUSANTARA UNIT BELAWAN FACILITIES is a significant concern that can affect the quality and market value of the product. By understanding the factors that affect impurities levels and implementing the recommendations outlined in this study, it is expected that the quality of raw palm oil can be maintained and meet the established standards.
