Potential usage of coconut fronds (cocos nucifera) in bioengineering approach

Abstract

Rapid development on highland areas and improper slope cutting has caused negative impacts on natural environment. These activities have contributed to extreme surface erosion and slope instability. Various conventional techniques have been used in controlling erosion and slope stability. The conventional approaches relatively expensive and require complex maintenance. Bioengineering approach offers environmental friend option, high aesthetic value and cheaper compared to different techniques. The use of natural products and biodegradable ensure a favorable environment for the growth of pioneer species. The application of bioengineering technique was carried out at Research Center UKM, Bukit Fraser, Pahang in order to study the suitability of studied material and identify appropriate installation procedure. This study involved the use of coconut fronds (Cocos nucifera) as slope cover material to minimize the soil surface erosion. The decomposition of coconut fronds contributes to soil organic content and also provides canopy for the growth of pioneer species. Besides that, live stakes of angsana species (Pterocarpus indicus) and leguminous species (Mucuna bracteata) were also combined in this technique. The live stake species of angsana contributes 10 the stability of slope through the root system meanwhile leguminous species able to increase the soil nitrogen content and provide nutrient for the growth of others pioneer species.
