Abstract

ABSTRACT The aim of this research is to determine the effect of FeCl 3 affected to lignocelullosic degradation of Sengon and Pine wood residue by Serpula lacrymans during incubation. which was showed by the changing value of Total Soluble Phenols (TSP), Total Reducing Sugar (TRS), weight loss and pH extract. The experimental design used is a Factorial Block Randomized Design with three factors: the type of wood (K) (Sengon and Pinewoods), the concentration of FeCl 3 (M) selected are 10, 30 and 50 µM and length of incubation (T): 0, 7, 14, 21, 28 and 35 days. The results revealed that the addition of FeCl 3 on both types of woods during incubation did not give a significant impact on the value of TSP, TRS, weight loss and pH. The best treatment in TSP production is Sengon wood was incubated for 28 days (0.064 mg/g). While the greatest amount of total reducing sugars is Pinewood, incubated for 28 days in the amount of 36.58 mg/g. The best in percentage of weight loss is Pinewood, incubated for 28 days contains 33,98% with pH extract 4.14 Keywords : biodegradation, lignocelullose, total soluble phenols, total reducing sugar.

Highlights

Wood waste is an organic compound, which composed from carbon materials such cellulose, hemicellulose, lignin and other carbohydrates
The biodegradation of lignocellulose waste released some sugars derived from both cellulose and hemicellulose which has normally been used as biofuel (Howard et al, 2003), mean while lignin consists of monoaromatic hydrocarbon which resulted derivative of aromatic compounds that can be used as natural binder, sub-bituminous-coal and sulfhur-free solid fuel which needed further analysis and exploration (Kamm and Kamm, 2004)
Total soluble phenols indicated the amount of phenol released from the degradation of lignin by Serpula lacrymans

Summary

Introduction

Wood waste is an organic compound, which composed from carbon materials such cellulose, hemicellulose, lignin and other carbohydrates. The use of wood waste is very limited for example it is used for firewood, organic fertilizer and bricket. It contains high of lignocellulose which is potential used as bioenergy material or value added chemical biobased (Wit et al, 2013). The use of Sengon and Pinewoods have been investigated to release high amount of lignocellulose. Sengon wood contains 36,73% of cellulose, 25,67% hemicelulosa. While pine wood consist of 44,7% cellulosa, 17,4% hemicelulosa, 28,42% lignin and 5,95% other compounds (Shi, 2010)
