“…Moreover, the ability of yeast to convert sugar is increased. In contrast to the research [16][17][18] that used a different fermentation raw material, namely sorghum starch, where the results of the study showed that the result of fermenting with the SSF method was more optimum compared to the SHF method. This can be seen from the concentration of ethanol produced with the SSF method resulted in a concentration in ethanol of 111,9 g/L with a 20% starch concentration used.…”

In 2021, Indonesia’s banana production is expected to reach 8.74 million tons. This substantial volume of bananas will generate a notable quantity of banana peel waste, constituting approximately one-third of the total banana fruit mass. Remarkably, banana peel waste retains 18.5% carbohydrates, which can be effectively converted into glucose, serving as a valuable feedstock for ethanol production. This research is focused on the ethanol production derived from Tanduk banana peel waste, employing a comparative analysis of the Separated Hydrolysis Fermentation (SHF) and Simultaneous Saccharification and Fermentation (SSF) techniques. Additionally, it explored varying raw material concentrations, specifically 200, 250, and 300 g/L. The SSF method integrated the use of cellulase enzymes, while the SHF method relied on HCl for the hydrolysis process. Microbial fermentation was facilitated by Saccharomyces cerevisiae, with a fermentation duration of 96 hours and sample collection at 12-hour intervals. The results demonstrated that higher concentrations of banana peel waste yield increased glucose production during the hydrolysis process, consequently leading to greater ethanol produced. The concentration of 300 g/L banana peel waste is optimal for producing ethanol in both procedures. However, the SHF approach demonstrates a superior ethanol concentration of 51%, surpassing the 33.7% achieved by the SSF method.

“…Pretreatment was carried out by adding 0.1 M NaOH to corncob powder, which was then hydrolyzed using an HCl solution. The results showed that the higher the acid concentration, the higher the ethanol content obtained [12]. The production of bioethanol from lignocellulosic materials requires four main process units, namely pretreatment, to break down lignocellulosic bonds and separate lignin from cellulose and hemicellulose polymer chains.…”

“…The more enzymes added, the greater the level of bioethanol produced because more glucose is converted to bioethanol. Microorganisms grow and develop activities to change the fermented material into the desired product in the fermentation process [12]. The optimum process of fermentation depends on the type of organism; adding factors that affect the fermentation process are temperature, initial pH of fermentation, inoculum, substrate, and nutrient content of the medium.…”

Penelitian ini bertujuan untuk menentukan pengaruh waktu terhadap kadar bioetanol dari kulit jagung manis dengan proses fermentasi. Sehingga pada penelitian selanjutnya ini bertujuan untuk mengoptimalisasi proses delignifikasi dengan variasi konsentrasi larutan penetralisasi NaOH. Berdasarkan tabel hasil analisa, kadar etanol tidak terdeteksi. Hal ini kemungkinan dipengaruhi pada tahap delignifikasi dan fermentasi. Pada proses delignifikasi kesalahan yang dilakukan yaitu kelebihan pada penambahan aquades dan NaOH yang seharusnya aquades sebanyak 1350 ml dan NaOH sebanyak 150 ml itu ditambahkan untuk semua sampel yang dipakai. Tetapi disini penggunaan aquades 1350 ml dan NaOH 150 ml digunakan pada setiap sampel. Refluks dilakukan selama 1,2 dan 3 jam. Serbuk kulit jagung dicuci dengan aquades dan dikeringkan. Penggantian pencucian dengan pemerasan, menyebabkan masih terdapat NaOH demikian juga kandungan lignin pada sampel tersebut.
