“…Microwave treatment enables shortening both of these stages resulting in a better drying rate. With better drying rate, the material becomes less hygroscopic as stated by [19]. Lignocellulosic material that treated with high temperature was less absorption and desorption rate as compared to untreated.…”

Abstract. In the decade, oil palm (Elaeis guineensis) in Malaysia is one of the conventional sources that will be rising, and the rate of biomass will considerably increase in yet to come. Presently, oil palm biomass is going through research and development and appears to be the most sustainable alternative. Investigations on oil palm biomass have been conducted to support in draw out waste of oil palm and in the meantime can help economic yield to the country. This study was expected to estimate the effect of power intensity properties of microwave modified oil palm trunk lumber. Microwave treatment of oil palm trunk samples was set of connections by using a microwave operating at 2.45 GHz with the liberated process input power intensity (600-1000W) were studied under the given condition. Impact and compression of the samples were tested. The analysis of properties of the fresh material and dry samples was employed by scanning electron microscopy. Oven drying technique also was involved as a comparison of the conventional drying process in this research. Based on the outcomes of this study, both drying methods improved the characteristics of the specimens.

This study was done to evaluate the flexural properties of microwave treated oil palm trunk (OPT) wood. The outer portion for basal position of the tree was chosen as it is the most stable part of oil palm trunk. Six treatment with the combination of different power input and exposure time were applied on the OPT wood blocks and one sample as control was not treated with any of the combination. The flexural properties of the microwave treated OPT wood referred as flexural modulus (MOE) and flexural strength (MOR) of the samples were analyzed. Microwave treatment number six has the highest flexural modulus and surpasses the untreated OPT.

The mechanical properties of natural fibre polyester composite was influenced by bonding efficiency between matrix and polyester matrix. This efficiency was related with the natural fibre and matrix characteristics. The natural fibre has a hydrophilic properties where else the polyester has a hydrophobic properties. The existent of organic and inorganic substances on the surface of natural fibre also contribute to the bonding strength. The modification using chemical treatment such as acetylation can overcome this problem. The chemical reaction participates in a long period cannot be completed in a short duration. The addition of some catalyst as an agent to speed up the reaction make the chemical reaction totally completed in short duration. In this study kenaf (Hibiscus cannabinus) polyester composite were manufactured and treated with acetic anhydride solution in 3 different percentages of catalyst that were 0.013%, 0.026% and 0.039% . In order to speed up the process modification in acetic anhydride solution catalyst (FeCl3) was added. Catalyst acts as a medium to complete reaction in limited time.It was found that,mechanical properties of polyester composite with addition of catalyst showed an increased trend and the highest was polyester composite with addition 0.036% of catalyst.
