| Summary: | Kenaf (Hibiscuss cannabinus.L) is one of lignocellulosic materials in which are
classified into biomass since it contains cellulose, lignin and hemicelluloses. Due to its complex
structure,it cannot be directly converted into end products such as ethanol and lactic acid. It has
to undergo pre-treatment process. Basically, the pre treatment process is on kenaf fibre with
different concentration of Sodium Hydroxide (NaOH), Sulfuric Acid (H2SO4) and Ammonia
(NH3) to hydrolyze the cellulose content in fibres. The pre-treatment results show that mild
H2SO4 hydrolysis is found to be the best pre-treatment method since it liberates the maximum
glucose content compared to others. In this study, the optimization of the glucose content from
this pre-treatment process occurs when the mass of raw material is 3g, its temperature is 160oC
and the time taken to hydrolyse is 35 minutes.
