Introduction

The synthesis of carboxymethyl polysaccharides from palm seeds (Arenga pinnata) is a crucial step in the development of innovative products with various applications. This process involves the extraction of polysaccharides from palm seeds, followed by eternalification reactions with monocloroacetate. The use of local raw materials, such as palm seeds, has high potential and can provide additional economic value and sustainable solutions in the use of waste.

Materials and Methods

The synthesis of carboxymethyl polysaccharides from palm seeds involves several stages. The first stage involves the extraction of polysaccharides from palm seeds, which are then analyzed using FT-IR spectroscopy. The second stage involves the eternalization process using monocloroacetate with NaOH as a catalyst. The reaction conditions, including the concentration of NaOH and the solvent used, are crucial in determining the degree of substitution of carboxymethyl polysaccharides produced.

In this study, variations in the comparison of NMCA/NNAOH, namely 0.50; 0.55; and 0.60, and the use of 96% ethanol as a solvent were explored. The purpose of this variation was to determine the effect of adding NaOH on the degree of substitution of carboxymethyl polysaccharides produced. The etherification process took place at 60 °C for 10 hours.

Characterization of Carboxymethyl Polysaccharides

After synthesis, the resulting Na-Carboxymethyl Polysaccharide must be converted into polysaccharide carboxymethyl by dissolving it in 2 M HCl, using a 70% methanol solvent. The characteristics of carboxymethyl polysaccharides can be identified in the presence of carbonyl groups (C = O) that are seen in the wave number 1730 cm^-1.

Results and Discussion

The results showed that the optimum condition for the synthesis of carboxymethyl polysaccharides from soft palm sugar seeds was obtained by adding NaOH weighing 0.88 grams or in the ratio of NMCA/NNAOH 0.50. In these conditions, the degree of substitution produced reached 1,600. Conversely, carboxymethyl polysaccharides originating from hard palm seeds only have a degree of substitution of 0.688.

Furthermore, the morphological analysis of the surface of the polysaccharide produced is carried out using SEM, which shows that the surface of the carboxymethyl polysaccharide becomes more rough due to changes in the form of polysaccharide granules.

Analysis of the Synthesis Process

The synthesis of carboxymethyl polysaccharides from palm seeds highlights the use of local raw materials that have high potential. Aren seeds, as a side product of the palm oil industry, are often not utilized optimally. The process of extraction of polysaccharides from palm seeds not only provides additional economic value, but also offers sustainable solutions in the use of waste.

The process of eternalification with monocloroacetate is a key step that affects the physical and chemical characteristics of the final product. The use of NaOH as a catalyst is important for increasing reaction efficiency, and variations in NaOH concentration show how the reaction condition can affect the degree of substitution. The higher degree of substitution usually correlates with better water soluble properties, which can expand the application of carboxymethyl polysaccharides in various industries, such as pharmacy, food, and cosmetics.

In terms of morphology, SEM analysis provides in-depth insight into changes in the surface structure of polysaccharides after synthesis. A more rough surface can increase the interaction between carboxymethyl polysaccharides and other matrices, so that it has the potential to improve the functionality of the final product.

Conclusion

The synthesis of carboxymethyl polysaccharides from palm seeds is not just a chemical process, but is also an innovative step in managing natural resources effectively. This research has the potential to encourage the use of palm seeds in broader applications and increase economic value for the surrounding community.

Future Directions

Future studies can focus on exploring the potential applications of carboxymethyl polysaccharides in various industries, such as pharmacy, food, and cosmetics. Additionally, the optimization of the synthesis process can be carried out to improve the efficiency and yield of the final product.
