Abstract

Local wisdom in utilizing swamp soil and water to improve the quality of gelam wood in Central Kalimantan becomes an interesting phenomenon. Improving the quality of wood can economize on the use of wood, which in turn preserves the forests in peat swamp lands. Gelam (Melaleuca sp.) woods that are mostly found in peat swamp forests can be used as piles/stakes in swamp soil, and they are durable for decades. The general objective of this study was to provide a scientific explanation of the effect of peat swamp soil and water on improving the quality of gelam wood either in barked and barkless conditions. This study was conducted by taking gelam trees that grew in Central Kalimantan. It was carried out for 18 months, and investigated the barked/barkless woods, media (swamp water, freshwater, peat swamp soil, and sandy soil) and 3 lengths of burying times. Wood properties analyzed were physical and mechanical properties. The standard of physical-mechanical property tests referred to British Standard 373.The results showed that the interaction between bark factor (A) and media (B) affected specific gravity. Barked wood produced the highest spesific gravity in swamp water medium. Water media (swamp and fresh water) improved the wood’s specific gravity more than soil media (swamp and sandy soil). The highest values of hardness, stress on Proportional Limit, and Modulus of Elasticity were in the medium of swamp soil. The improvement of the quality of gelam woods, which were either buried or used as stakes/piles, was allegedly resulted from the swamp water infiltrating into gelam woods that thereby increased the specific gravity.

Abstract

Wood durability is a crucial factor in its utilization, especially in tropical regions with high humidity levels. Terantang wood is classified as lightweight wood with low resistance to wood-degrading organisms. Preservation using liquid smoke is one of the alternative methods to enhance the durability of Terantang wood. This study aims to evaluate the effectiveness of liquid smoke derived from Gelam wood (Melaleuca sp.) as a natural preservative for Terantang wood. The preservation process was conducted using a cold-soaking method for 48 hours with three different liquid smoke concentrations: 10%, 20%, and 30%. After treatment, the wood samples were dried and tested to determine their retention and absorption values. The results showed that increasing the liquid smoke concentration directly correlated with higher retention and absorption values. The 30% concentration exhibited the highest retention (0.055 g/cm³) and absorption (0.241 g/cm³), indicating superior effectiveness in enhancing wood durability. Retention was highest near the heartwood, while absorption was greater near the sapwood. These findings suggest that Gelam wood liquid smoke has significant potential as an eco-friendly and cost-effective wood preservative. Its use can serve as a safer alternative to synthetic preservatives, supporting more sustainable wood processing practices.
