Physical and Mechanical Properties of Raru Wood Dahanon (Cotylelobium Lanceolatum) and Songal (Hopea Songal)

Introduction

In the realm of sustainable development, the utilization of local resources has become a crucial aspect of reducing our carbon footprint and promoting eco-friendly practices. The Raru wood, a type of wood originating from North Sumatra, has been a staple in the traditional practices of the local community for centuries. The wood is often used as a mixture in making wine and traditional alcoholic drinks. However, its potential extends beyond its traditional uses, and it is essential to conduct research on its physical and mechanical properties to optimize its use in modern construction.

Background

The Raru wood, also known as Dahanon and Songal, is a type of wood that has been used by the local community for centuries. The wood is known for its unique properties, which make it an ideal choice for various applications. However, despite its potential, the wood has not been extensively studied, and its properties are not well understood. This study aims to bridge this knowledge gap by investigating the physical and mechanical properties of the Raru wood from Central Tapanuli.

Methodology

The study involved collecting tree samples from Central Tapanuli and dividing them into three parts: the base, middle, and tip of the stem. The analysis was carried out in accordance with the BS-373 standard, which includes various parameters of the physical properties of wood, such as specific gravity, water content, and depreciation, as well as mechanical properties that include modulus elasticity (MOE), broken modulus (MOR), violence, and compressive strength and strength Tug parallel to the fiber.

Results

The results of the study showed that the physical and mechanical properties of the Raru wood vary depending on the direction of the stem. In the vertical direction, the base of the stem has a better quality compared to the end. However, in the horizontal direction, the nature of the wood varies. The specific gravity of the Raru wood is classified as strong class I, indicating that it is durable and strong. The stability of the dimensions of the Raru wood is also classified as good, seen from the ratio of tangential and radial shrinkage that reaches one.

Mechanical Properties

The mechanical properties of the Raru wood are suitable for use as a heavy construction material, such as electricity and shipping poles. The selection of wood as a construction material is not only based on its strength but also on its ability to survive in various environmental conditions, making it an ideal choice for outdoor applications.

Conclusion

The Raru wood, Dahanon and Songal, has the potential to be used not only in traditional practices but also in modern construction. This study provides useful information about the properties of the wood that can be used as a reference for the wood industry and infrastructure development. With a better understanding of the physical and mechanical properties of the Raru wood, it is hoped that the community can better use local potential in a more sustainable and efficient way.

Recommendations

Based on the findings of this study, the following recommendations are made:

  • Further research should be conducted to investigate the properties of the Raru wood in different environmental conditions.
  • The Raru wood should be considered as a potential material for heavy construction applications, such as electricity and shipping poles.
  • The local community should be educated on the potential uses of the Raru wood and its benefits in sustainable development.

Future Directions

The study of the Raru wood has opened up new avenues for research and development. Future studies should focus on investigating the properties of the wood in different environmental conditions and exploring its potential uses in various applications. Additionally, the local community should be involved in the development of sustainable practices that utilize the Raru wood, promoting eco-friendly practices and reducing our carbon footprint.

Limitations

This study has several limitations, including:

  • The sample size was limited to three tree samples, which may not be representative of the entire population.
  • The analysis was carried out in accordance with the BS-373 standard, which may not be applicable to all types of wood.
  • The study did not investigate the properties of the Raru wood in different environmental conditions.

Future Research Directions

Future research should focus on investigating the properties of the Raru wood in different environmental conditions, such as temperature, humidity, and light exposure. Additionally, the study should explore the potential uses of the Raru wood in various applications, such as furniture making, construction, and packaging.

Conclusion

In conclusion, the Raru wood, Dahanon and Songal, has the potential to be used not only in traditional practices but also in modern construction. This study provides useful information about the properties of the wood that can be used as a reference for the wood industry and infrastructure development. With a better understanding of the physical and mechanical properties of the Raru wood, it is hoped that the community can better use local potential in a more sustainable and efficient way.
