Abstract/Executive Summary
This study aimed to examine the bioethanol yield potential of varying ratios of Jicama (J) and Footstool Palm Stalk (FPS). The prototype used a mixed feedstock approach and was developed using the Separate Hydrolysis and Fermentation (SHF) method to extract and ferment sugars to produce ethanol. The study measured bioethanol yields by employing a posttest-only controlled group design consisting of a negative control group and three experimental groups. The results demonstrated that Experimental 3 exhibited the highest average initial sugar yield (3.71g), while the Negative Control showed the lowest average initial sugar (1.5g), showing the high sugar potential of Experimental 3 FPS on sugar yields. However, in terms of yield, the negative control displayed the highest average (0.77), while Experimental 3 had the lowest average (0.35), but most groups demonstrated a relatively high bioethanol yield in comparison to previous bioethanol studies. Furthermore, a significant difference was found between the mean yields of the control and experimental groups (p-value = 0.018), while in group pairs, only the Negative Control and Experimental 3 had a significant difference (p-value = 0.013), and the other group pairs had insignificant differences. These results indicate that the study’s methodology caused FPS to inhibit fermentation, reducing bioethanol yield. The study highlights the significance of raw material selection and in-depth methodologies in maximizing the yield potential of mixed bioethanol feedstocks, offering insights for advancements in bioethanol production and the utilization of J and FPS as a potential sustainable energy source.
