$Factors Affecting VFA Levels in Latex$

Effect of Storage Time on Volatile Fatty Acid Value (VFA) in Latex in Making Rubber Crumb at PT. Bridgestone Sumatra Rubber Estate

Introduction

The quality of latex is a crucial factor in determining the quality of crumb rubber produced at PT. Bridgestone Sumatra Rubber Estate. One important parameter analyzed is the level of volatile free fatty acids, known as volatile fatty acid (VFA). VFA levels in latex must be maintained so as not to exceed the limit set by the SNI standard, which is less than 0.070. If the VFA level exceeds this limit, it can result in a decrease in plasticity and the quality of the rubber rubber. Understanding the importance of VFA levels in latex is essential for ensuring the quality of crumb rubber production.

Volatile Fatty Acids (VFA) in Latex

Volatile free fatty acids are formed as a result of microbial activity that breaks down protein into fatty acids. Therefore, latex storage time greatly affects the resulting VFA levels. Determination of free fatty acid levels in latex is carried out by distillation-titration method using a standard solution of BA (OH) 2 0.005 N. The results show that VFA levels in latex are in the range of 0.04 to 0.06 when stored in the span of 0 to 9 Clock, which means still meets the established standards. The formation of VFA in latex is a natural process that can be influenced by storage time and conditions.

Factors Affecting VFA Levels in Latex

Several factors can affect VFA levels in latex, including storage time, temperature, and humidity. Storage time is a critical factor that can influence the growth of microbes that produce fatty acids. The longer the storage time, the higher the risk of increasing VFA levels. Monitoring storage time and conditions is essential for maintaining VFA levels within the permitted limits.

Importance of Controlling Storage Time

The importance of maintaining VFA levels in latex cannot be underestimated. High VFA levels can cause crumb rubber to become unplusome and difficult to process, which in turn can have an impact on the entire rubber production chain. Therefore, controlling latex storage time is one of the important strategies in quality management at PT. Bridgestone Sumatra Rubber Estate. Controlling storage time is essential for ensuring the quality of crumb rubber production.

Optimal Storage Time

The optimal storage time is the key to minimizing the growth of microbes that produce fatty acids. Based on data, storage carried out in a longer period of time than 9 hours will increase the risk of increasing VFA levels. This shows that companies need to implement strict storage management systems, such as monitoring time and storage conditions, to ensure that latex remains in the best condition before being processed into crumb rubber. Implementing strict storage management systems is essential for maintaining VFA levels within the permitted limits.

Use of Modern Technology and Automation

In this context, the use of modern technology and automation in monitoring the latex storage environment can also be an added value. For example, integrated temperature and humidity sensors can help maintain an ideal condition for latex, thereby reducing the possibility of excessive VFA formation. The use of modern technology and automation can help improve the quality of crumb rubber production.

Education and Training

In addition, education for labor about the importance of controlling storage time and its impact on the quality of the final product is also very necessary. With high awareness about latex quality and how the storage process affects VFA levels, it is expected to create a more responsive work culture to quality issues. Education and training are essential for ensuring that labor understands the importance of controlling storage time.

Conclusion

Overall, good management of latex storage time can contribute significantly to the success of crumb rubber production at PT. Bridgestone Sumatra Rubber Estate. By maintaining VFA levels within the permitted limits, companies can not only improve the quality of their products but also ensure sustainability and efficiency in the production process. Good management of latex storage time is essential for ensuring the quality of crumb rubber production.
