Studi Pemanfaatan Spirulina Plantesis dan Chlorella Pyrenoidosa Selama Kultivasi: Implikasinya Terhadap Produksi Bioetanol

Abstract

This study investigates the potential of Spirulina platensis and Chlorella pyrenoidosa in microalgae cultivation for bioethanol production. Microalgae are highly efficient in absorbing carbon dioxide through photosynthesis, making them a promising resource for reducing global warming and providing a sustainable biofuel alternative. Over a 30-day cultivation period, changes in color intensity were monitored for both microalgae species using Python-based simulations. The findings indicated notable differences in color intensity between Spirulina and Chlorella, which corresponded to distinct growth phases and biomass accumulation. By optimizing fluid dynamics and carbon dioxide absorption, it is possible to produce microalgal biomass rich in carbohydrates. This biomass can then be processed into bioethanol through hydrolysis and fermentation. Therefore, leveraging photobioreactor technology and optimizing cultivation parameters presents an eco-friendly solution for sustainable bioethanol production from microalgae.
