The Effect of Stem Height and Number of Layers on Physical Properties and Mechanical Properties of Laminated Board from Palm Oil (Elaeis guineensis Jacq) with Polyvinyl Acetate (PVAC) Adhesive

Introduction

Palm oil is one of the leading plants in the plantation sector, with its area increasing year by year. However, this growth has led to the conversion of natural forests into oil palm farming, resulting in a decrease in the availability of natural wood. As a solution, the use of oil palm stems through the manufacture of laminated boards is a promising alternative. This article discusses the effect of stem height and number of layers on physical properties and mechanical properties of laminated board from palm oil (Elaeis guineensis Jacq) with Polyvinyl Acetate (PVAC) adhesive.

The Importance of Utilizing Oil Palm Stems

The process of making a laminated board is an innovative step in utilizing materials that may be ignored beforehand. The use of oil palm stems for laminated products provides added value, both in terms of economy and the environment. By utilizing oil palm stems, we can reduce the demand for natural wood and help preserve the environment. Additionally, the use of oil palm stems can provide a new source of income for farmers and communities involved in palm oil production.

Physical Properties of Laminated Board

The physical properties of the laminated board produced from palm oil (Elaeis guineensis Jacq) using Polyvinyl Acetate (PVAC) adhesive showed positive results. For water content parameters, the laminated board has met JAS 243: 2003 standards, while for density, the standard does not include the requirements. However, the density of the laminated board is an important factor to consider, as it can affect the overall quality and performance of the board.

Mechanical Properties of Laminated Board

In terms of mechanical properties, especially the value of modulus of elasticity (MOE) and modulus of rupture (MOR), this laminated board does not meet the provisions specified in JAS 243: 2003. The MOE and MOR are critical factors in determining the strength and durability of the laminated board. However, the results of this study suggest that the stem height and number of layers used do not have a significant impact on the value of MOE and MOR.

The Effect of Stem Height and Number of Layers

Research also shows that the stem and number of layers used significantly affect the water content of the laminated board. However, both did not show a significant impact on the value of density, MOE, and MOR. This illustrates that although these factors affect the physical properties of the board, they do not contribute enough to more complex mechanical properties.

Optimizing the Performance of Laminated Board

From the recapitulation results, the laminated board that has the best performance is found at the base of the stem with seven layers. This shows that variations in the height of the stem and the number of layers can affect the characteristics of the laminated board produced. By selecting the right layer and utilizing the optimal part of the stem, laminated board products can have better quality.

Sustainability and Future Development

In the context of sustainability, the use of oil palm stems for making laminated boards not only provides alternative building materials, but also helps reduce deforestation by utilizing existing resources more efficiently. With further research and innovation in production techniques, laminated boards from oil palm can be one of the material choices that are environmentally friendly and economical for future development.

Conclusion

In conclusion, the use of oil palm stems for making laminated boards is a promising alternative to natural wood. The physical properties of the laminated board produced from palm oil (Elaeis guineensis Jacq) using Polyvinyl Acetate (PVAC) adhesive showed positive results. However, the mechanical properties of the laminated board do not meet the provisions specified in JAS 243: 2003. Further research and innovation in production techniques are needed to optimize the performance of laminated boards from oil palm.
