Determining the Dry Rubber Content in Fresh Latex at PT. Nusantara III Sarang Giting: A Study on the Gravimetric Method

Introduction

The rubber industry plays a vital role in the global economy, with Indonesia being one of the largest producers of natural rubber. PT. Nusantara III Plantation Sarang Giting is one of the leading rubber plantations in Indonesia, producing high-quality Ribbed Smoked Sheet (RSS) rubber. In this study, we will discuss the determination of dry rubber content in fresh latex at PT. Nusantara III Sarang Giting using the gravimetric method.

The Importance of Dry Rubber Content in Fresh Latex

The dry rubber content in fresh latex is a critical parameter in the rubber industry, as it determines the quality of the final product. The Indonesian National Standard (SNI) 06-0001-1987 sets the standard for dry rubber levels in a range of 28-30%. PT. Nusantara III Sarang Giting has determined the level of dry rubber in fresh latex using the gravimetric method, which involves the separation of rubber particles from latex through clumping using formic acid with a concentration of 2-2.5%. The result of this treatment shows that the dried rubber content obtained is an average of 29.30%.

The Gravimetric Method: A Reliable Analytical Method

The gravimetric method used in determining the dry rubber content has several advantages. First, this method is known as one of the most accurate and reliable analytical methods to determine the composition of the material. In this way, the results obtained are very close to reality because it involves direct measurement of mass from the dry rubber produced. The use of formic acid as a clotting agent helps in separating rubber from latex liquid without damaging the quality of the rubber produced. Thus, the final product obtained not only meets the standards, but also maintains the physical and chemical properties of quality rubber.

The Importance of Compliance with SNI Standards

Compliance with SNI standards is very important in the rubber industry, because this standard provides product quality assurance. With dried rubber content at 29.30%, PT. The Nusantara III Sarang Giting plantation not only meets the requirements, but also shows its commitment to high-quality production. This has positive implications for the competitiveness of the company in the global market, where product quality is one of the determinants of success. In this context, the application of the gravimetric method and compliance with SNI standards also reflects the company's efforts to protect the environment. The process used is minimal negative impact on the environment because it uses relatively safe materials.
