Introduction

The utilization of natural resources has become a crucial aspect in the development of sustainable industries. One such resource is the Areca catechu linn, commonly known as the Areca nut or Pinang Batang. This plant is widely cultivated in Indonesia and has been used for various purposes, including as a raw material for the production of liquid adhesives. The potential of the Areca nut as a liquid adhesive material has been explored in this study, with a focus on the depth of the stem.

Background

The Areca nut is a lignocellulose-rich plant that has been used as a raw material for the production of various products, including paper, textiles, and adhesives. The plant's stem is particularly rich in lignin, a complex organic compound that is responsible for the plant's rigidity and resistance to decay. The lignin content in the Areca nut stem makes it an attractive raw material for the production of liquid adhesives.

Methodology

The study involved the collection of Areca nut stems from various depths, namely the outside (L), the middle (T), and the inside (D). The stems were then processed to extract the lignin-rich material, which was mixed with technical phenols, H2SO4 98%, NaOH 50%, and formaldehyde 37% at 90 ° C for 2 hours. The resulting liquid adhesive was then analyzed for its physical and chemical properties.

Analysis Based on the Depth of the Stem

Appearance

The outside of the Areca nut stem has a dark red color and is free of dirt. This suggests that the outer layer of the stem is rich in lignin, which is responsible for the plant's rigidity and resistance to decay.

The Level of Acidity (pH)

The three parts of the stem have a different acidity level, namely 13 (L), 11 (T and D). This suggests that the acidity level of the stem increases with depth, with the outside layer being the most acidic.

Viscosity

Viscosity is not mentioned in the description, but it needs to be further investigated. Viscosity is an important property of liquid adhesives, as it affects the flow and spreading of the adhesive.

Density

The outside and middle have a density of 1,152 (L) and 1,173 (T). This suggests that the density of the stem increases with depth, with the outside layer being the densest.

Content of Solids

The middle and inside have a solid content of 40% (T and D). This suggests that the solid content of the stem increases with depth, with the middle and inside layers being the richest in solids.

Gelatin Time

Gelatin time for the three parts is 332 minutes (L), 315 minutes (T), and 305 minutes (D). This suggests that the gelatin time of the stem decreases with depth, with the outside layer being the slowest to gel.

Free Formaldehyde

The three parts of the stem meet SNI 06-4565-1998 with a free formaldehyde content of 1.69% (L), 1.30% (T), and 1.24% (D). This suggests that the free formaldehyde content of the stem decreases with depth, with the outside layer being the highest in free formaldehyde.

Ash Content

Not mentioned in the description, but it needs to be further investigated. Ash content is an important property of liquid adhesives, as it affects the adhesive's strength and durability.

Conclusion and Implications

The results showed that the Liquid of Pinang Pinang Wood Liquid had characteristics that were more similar to the formaldehyde phenol adhesive compared to the outside and inside. This shows the potential of the Areca nut as raw material for liquid adhesive, especially the middle.

Benefits of the Utilization of Pinang Batang

Reducing Areca nut waste which is often wasted.
Creating new business opportunities in the adhesive industry.
Increase the added value of betel nuts.
Reducing dependence on imported adhesive raw materials.

Suggestion

Conducting further research to optimize the process of making betel nuts.
Test other characteristics such as bond strength, water resistance, and resistance to temperature.
Conduct economic and environmental analysis in the use of Pinang Batang as adhesive raw material.
Building partnerships with related industries to develop adhesive products from Batang Pinang.

Conclusion

The utilization of Pinang Batang as a liquid adhesive material has great potential and benefits. The study has shown that the Areca nut stem can be used as a raw material for the production of liquid adhesives, with the middle layer being the most suitable. Further research is needed to optimize the process of making betel nuts and to test other characteristics such as bond strength, water resistance, and resistance to temperature. The use of Pinang Batang as a liquid adhesive material can be an innovative and sustainable solution to meet the needs of the adhesive industry in Indonesia.
