Screening of Factors Affecting Ferulic Acid Production from Oil Palm Frond Waste via Mix Culture Hydrolysis: Interaction between Factors
Fiber-pressed oil palm frond (FPOPF) was used to produce ferulic acid via hydrolysis using mix culture. FPOPF substrate was acclimatized with the soil from palm oil plantation for 30 days to be used as the mix culture. The FPOPF substrate has a ratio of FPOPF to water at 1:10. The experimental des...

| Summary: | Fiber-pressed oil palm frond (FPOPF) was used to produce ferulic acid via hydrolysis using mix culture. FPOPF
substrate was acclimatized with the soil from palm oil plantation for 30 days to be used as the mix culture. The
FPOPF substrate has a ratio of FPOPF to water at 1:10. The experimental design was a two-level factorial analysis
at half fraction with five factors, resulting a total of 16 runs. This design was selected using Design Expert 7.0
software. The factors studied were temperature (26°C to 40°C), pH value (5 to 9), agitation speed (0 and 150 rpm),
inoculum percentage (2% to 10%) and response time (1 day to 3 days). From ANOVA, the result was found to be
significant with quadratic model. The coefficient of determination obtained was 0.8978. Four factor interactions
were discovered among the factors. Temperature and pH value were the main contributor to the hydrolysis with
23.34% and 23.76% of contribution percentage, respectively. |
