Introduction

Sugar is one of the staple foods obtained from raw sap that contains various impurities, including acids. In the process of making sugar, product quality is determined by the quality of the sap produced from the purification process. The Kwala Hadu Sugar Factory, PTP Nusantara II Langkat, uses a unique method of purifying the sap by adding limestone milk (Caoh) 2 and SO2 gas. This process involves the use of SO2 gas as a precipitate, where the addition of excessive lime milk will be neutralized by SO2 gas.

How Does Lime and SO2 Gas Milk Work in Purification of the Sap?

The addition of lime milk (Caoh) 2 serves to raise the pH of the sap, thus making the sap more alkaline. This aims to precipitate the dirt contained in the sap, such as protein and dyes. This process is called calcification. However, the addition of excessive lime milk will cause the pH of the sap to be too high. Therefore, SO2 gas is needed to neutralize excess lime milk. SO2 gas will react with lime milk to form calcium sulfite (Caso3), which will then settle. This process is called sulfitation.

The Advantage of Using Limestone and SO2 Gas Milk

The use of limestone and SO2 gas milk in the purification process of sap has several advantages. These include:

Improving the quality of the sap: Calcification and sulfitation process helps separate the dirt and dyes from the sap, produces a more clear and high-quality sap.
Preventing spoilage: The addition of SO2 gas helps inhibit the growth of microorganisms that can cause spoilage.
Increasing the efficiency of purification: The use of lime milk and SO2 gas appropriately can increase the efficiency of the purification process of sap, thereby reducing the use of chemicals and energy.

Challenges in Setting PH Nira

Determining the right amount of lime and SO2 gas is very important in the purification process of sap. The advantages or disadvantages of the addition of these two ingredients can have a negative impact on the quality of the sugar produced. Some of the challenges in setting PH Nira include:

Excess lime milk: Can cause crust formation in equipment and slow down the process of crystallization of sugar.
Lack of lime milk: Can cause sap that is not enough to precipitate dirt and dyes optimally.
Lack of SO2 gas: Can cause the pH of the sap is too high and the process of crystallization of sugar is inhibited.

Importance of Control and Monitoring

In order for the purification process to run optimally, the Kwala Honey Sugar Factory must carry out strict control and monitoring of the addition of lime and SO2 gas milk. This includes:

Use of measuring devices pH: PH measuring devices are used to control the pH of the sap in real-time.
Monitoring and Analysis: The Expert Team in the Sugar Factory conducts periodic monitoring and analysis to ensure the addition of lime and SO2 gas milk in accordance with the specified standards.

Conclusion

By applying the right purification process of sap, the sugar factory kwala honey can produce high-quality and efficient sugar. This process involves the addition of lime and SO2 gas which is strictly controlled to reach the optimal pH of the sap. Through proper control and monitoring, a sugar factory can ensure optimal sugar production process and produce high-quality products.

Recommendations

Based on the study, the following recommendations are made:

Regular monitoring and analysis: The sugar factory should conduct regular monitoring and analysis of the addition of lime and SO2 gas milk to ensure that the process is running optimally.
Use of measuring devices pH: The sugar factory should use PH measuring devices to control the pH of the sap in real-time.
Training and education: The sugar factory should provide training and education to its employees on the importance of control and monitoring of the addition of lime and SO2 gas milk.

Future Research Directions

Future research directions include:

Investigating the effects of different concentrations of lime and SO2 gas milk on the quality of the sap.
Developing a more efficient method of purifying the sap using limestone and SO2 gas milk.
Investigating the use of alternative methods of purifying the sap, such as using enzymes or other chemicals.

Limitations of the Study

The study has several limitations, including:

Limited sample size: The study was conducted on a small sample size, which may not be representative of the entire sugar factory.
Limited data collection: The study only collected data on the addition of lime and SO2 gas milk, and did not collect data on other factors that may affect the quality of the sap.
