Analisa Karakteristik Asap Cair Hasil Pirolisis Biomassa Tempurung Kelapa dengan Metode Destilasi

Abstract

Coconut shell is one type of biomass from agricultural waste that can be utilized into liquid smoke, because coconut shell contains 26.5% cellulose, 27.7% hemicellulose and 29.4% lignin. Liquid smoke can be utilized as an antioxidant and food preservative. This study aims to determine the characteristics of liquid smoke after purification using distillation and filtration using active zeolite and activated carbon. The method used in this research is distillation with temperature variations of 100, 110, 120OC. Based on the results of the study, it is known that the characteristics of liquid smoke at a temperature of 100OC are pH 2.6; phenol content 10.96%; acid content 37.74%; specific gravity 1.011 gr/mL; clear yellowish color; and light smoke odor (not pungent), at a temperature of 110OC is pH 2.3; Phenol content 12.52%; Acid content 41.54%; Specific gravity 1.010 gr/mL; Yellow-brown color; and Moderate smoke odor (Slightly Pungent), at a temperature of 120OC pH 2.0; Phenol content 14.89%; Acid content 43.99%; Specific gravity 1.017 gr/mL; Yellow color; and Moderate smoke odor (Pungent). The quality of liquid smoke produced is close to the SNI 8985: 2021 standard which is the quality standard for liquid smoke.
