Improving the Durability of Tisuk Wood through Preservation Research

Kistang - Tisuk (Hibiscus macrophyllus), a fast-growing tree species commonly found on the island of Java, has been a valuable resource in various applications, including construction, furniture, and crafts. However, one of its weaknesses lies in its low durability, especially when used as lumber.

Improving the Durability of Tisuk Wood through Preservation Research

In an effort to enhance the lifespan of tisuk wood, recent research has focused on its preservation through cold soaking using a Boric Acid Equivalent (BAE) solution.

This study collected tisuk wood samples from community forests in Sukamulih Village, Sariwangi District, Tasikmalaya Regency. Several research parameters observed included wood thickness (2.5 cm, 5 cm, 7.5 cm, and 10 cm), soaking duration (3 days, 5 days, and 7 days), and the concentration of the preservative solution (5% and 10%).

The research findings revealed that the retention of the preservative solution varied among different wood thicknesses but showed no significant difference in soaking duration. The level of preservative penetration did not exhibit significant differences in all treatment conditions.

This research has a positive impact as its results meet the requirements of the Indonesian National Standard (SNI) regarding preservative retention and penetration. Therefore, it is recommended to preserve tisuk wood using a 5% concentration of the preservative solution with a soaking duration of 3 days for various wood thicknesses (2.5 cm, 5 cm, 7.5 cm, and 10 cm).

These findings hold significant potential for increasing the utilization of tisuk wood in various applications, such as construction, furniture production, and crafting.

With the improved durability of tisuk wood, we can utilize this resource more efficiently, which can also have a positive impact on the environment. This research marks an important step in conserving and utilizing Indonesia's natural wealth more sustainably.
