Abstract

Drying is an important stage in the preparation of bamboo blades for kelarai panel production because it directly affects the final moisture content of the material. In current practice, conventional sun drying remains widely used by local craftsmen due to its low cost and simple application, although the method is highly dependent on weather conditions and may produce inconsistent results. This study aims to compare the moisture content of Semantan bamboo (Gigantochloa scortechinii) blades subjected to sun drying and oven drying in order to determine the more effective drying method for kelarai production. An experimental approach was adopted in which bamboo samples were dried under different conditions, namely sun drying, oven drying at 30°C for 12 hours, and oven drying at 50°C for 2 hours, with and without boron treatment. Moisture content was calculated based on the difference between initial and final weight after drying. The findings show that oven drying produced lower and more consistent moisture content than sun drying, while oven drying at 50°C for 2 hours recorded the lowest moisture content among all methods tested. These results indicate that controlled drying provides a more reliable approach for reducing moisture content in bamboo blades intended for kelarai panel production.

Abstract

The long-term performance and durability of bamboo kelarai panels are significantly governed by the mechanical properties of the individual bamboo strips that constitute their interwoven configuration. This research is intended to assess the durability of bamboo kelarai panels through a detailed examination of the influence of moisture content and boron-based preservation treatment on their tensile strength characteristics. An experimental laboratory methodology was implemented, employing Gigantochloa scortechinii (commonly referred to as Semantan bamboo) as the primary material, wherein the specimens were systematically classified into four distinct categories according to moisture condition (elevated and reduced) and treatment status (treated with boron and untreated). Tensile strength evaluation was carried out using a Universal Testing Machine, with peak stress values meticulously measured and documented for subsequent analytical interpretation. The findings reveal a pronounced inverse correlation between moisture content and tensile strength, whereby specimens with reduced moisture levels exhibited superior strength performance alongside greater structural stability. Furthermore, samples subjected to boron treatment demonstrated more uniform tensile behaviour, suggesting an improvement in fibre cohesion and internal structural integrity. Notably, the synergistic combination of low moisture content and boron treatment resulted in the highest recorded tensile strength values among all tested groups. Collectively, these outcomes establish a robust scientific foundation for enhancing the durability of kelarai panels through effective moisture regulation and appropriate preservation techniques, thereby contributing to the advancement of more dependable, resilient, and sustainable bamboo-based construction materials within the field of architecture.
