Isolasi Lignin Limbah Kulit Batang Sagu Dengan Metode Organosolv

---

ABSTRACT
Sago bark is a byproduct of the sago starch filtering process that contains lignocellulosic components. The separation of these lignocellulosic components can be achieved through a lignification process. One chemical method of delignification employs an organosolv solvent. This research aims to determine the optimal concentrations of formic acid and acetic acid to achieve the highest lignin yield from sago bark waste and to characterize the lignin obtained.The study was conducted using Response Surface Methodology (RSM) with a central composite design (CCD), resulting in 13 experimental units. The treatments involved varying concentrations of formic acid and acetic acid across three levels for each factor. Observations were made on yield, water content, ash content, and acidity. The data obtained from this research were analyzed using analysis of variance (ANOVA), which included the significance of the P-value related to the model, lack of fit, and the difference between the adjusted R-squared and predicted R-squared for adequate precision. The analysis was performed using Design Expert 13 software.The results indicated that variations in formic acid concentrations had a significant effect on yield, water content, ash content, and acidity. Specifically, a concentration of 53% formic acid and 78% acetic acid produced the highest yield of 32.108%, with a water content of 5.524%, an ash content of 6.933%, and an acidity level of 2.006.
