SYNTHESIS AND CHARACTERIZATION OF BIOETHANOL FROM BANANA PEEL (MUSA ACUMINNATA)
Abstract
ABSTRACT
This study investigates the production of bioethanol from Banana peels, an underutilized agricultural waste. The experiment involved several steps, including sample collection, pretreatment with H2SO4, fermentation using Saccharomyces cerevisiae, and distillation. The physicochemical properties of the produced bioethanol were evaluated, revealing a dark brown color, an unpleasant odor, and various chemical characteristics. Key findings include an iodine value of 16g I2/100g, acid value of 2.953 mg KOH/g, and a refractive index of 1.3726. Other properties such as density (1.147g/mL), specific gravity (0.956 g/cm³), cloud point (3°C), and a 60% yield were also recorded. Fourier-transform infrared spectroscopy (FTIR) analysis confirmed the presence of functional groups typically found in bioethanol, including O-H(3329.08cm-¹), C=O(1636.63cm-¹), and C-O(1079.80cm-¹ and 1049.40cm-¹) stretching. The results suggest that Banana peel could serve as a viable source for bioethanol production, providing an eco-friendly and renewable energy alternative. However, further purification is recommended to improve bioethanol quality and meet industry standards.
