Introduction

Bioethanol is an environmentally friendly alternative fuel that can be produced from various plant sources, including durian seeds. Durian seeds are rich in carbohydrates and sugar, making them a potential source for bioethanol production. This study examines the effect of yeast mass variations and fermentation time on the efficiency of bioethanol production from durian seeds.

Background

Bioethanol is a promising alternative fuel that can reduce dependence on fossil fuels and promote economic development based on local resources. The production of bioethanol from plant sources such as durian seeds is an important step towards renewable and sustainable energy. However, the efficiency of bioethanol production from durian seeds depends on various factors, including yeast mass and fermentation time.

Methodology

This study uses three yeast mass variations, namely 3%, 6%, and 9%, with a fermented pH of 4.5. Fermentation time is varied to 0, 24, 48, 72, and 96 hours. The results showed that the highest bioethanol concentration, 84,205%, was achieved in a 6% yeast mass with a fermentation time of 48 hours.

Effect of Yeast Mass

The use of more yeast (6%) gives higher bioethanol results compared to lower yeast mass (3% and 9%). This is because the yeast acts as a catalyst in the fermentation process, describing sugar into alcohol. However, the addition of too much yeast (9%) can actually inhibit the fermentation process because yeast competes to get limited nutrition.

Effect of Fermentation Time

The optimal fermentation time to produce the highest bioethanol is 48 hours. Shorter fermentation time (0, 24 hours) is not enough for yeast to decompose all sugar into alcohol, while longer fermentation time (72, 96 hours) can cause a decrease in bioethanol concentration because the yeast starts to die or produce a by-product.

Results and Discussion

The results of this study show that the highest bioethanol concentration, 84,205%, was achieved in a 6% yeast mass with a fermentation time of 48 hours. This suggests that the optimal combination of yeast mass and fermentation time is 6% yeast mass and 48 hours of fermentation time.

Benefits and Implications

This study provides important information in the optimization of bioethanol production from durian seeds. By determining the combination of yeast mass and proper fermentation time, the efficiency of bioethanol production can be increased. This opens opportunities to utilize durian seed waste as renewable energy raw materials, reduce dependence on fossil fuels, and encourage economic development based on local resources.

Recommendations and Suggestions

Further research needs to be done to examine the effect of other factors such as fermentation temperature and yeast type on bioethanol production from durian seeds.
Further research is needed to evaluate the potential of durian bioethanol as an alternative fuel, including testing the quality and bioethanol performance produced.

Conclusion

The utilization of durian seeds as a source of bioethanol is an important step in an effort towards renewable and sustainable energy. The development of technology and optimization of the bioethanol production process of durian seeds can make a significant contribution to environmental sustainability and energy security.

Future Research Directions

Future research should focus on optimizing the bioethanol production process from durian seeds, including the effect of other factors such as fermentation temperature and yeast type. Additionally, further research is needed to evaluate the potential of durian bioethanol as an alternative fuel, including testing the quality and bioethanol performance produced.

Limitations of the Study

This study has several limitations, including the use of a limited number of yeast mass variations and fermentation times. Additionally, the study only examined the effect of yeast mass and fermentation time on bioethanol production from durian seeds, and did not consider other factors that may affect the production process.

Conclusion

In conclusion, this study provides important information on the effect of yeast mass and fermentation time on bioethanol production from durian seeds. The results of this study suggest that the optimal combination of yeast mass and fermentation time is 6% yeast mass and 48 hours of fermentation time. This study has implications for the development of technology and optimization of the bioethanol production process of durian seeds, and can make a significant contribution to environmental sustainability and energy security.
