Biopolymer manufacturing from pectin extraction of jackfruit waste to increase oil production in EOR

Abstract

This research was conducted with the aim of making an alternative, nature-based biopolymer formed from the extraction of jackfruit peel pectin as a substitute for commercial polymers. The manufacture of this biopolymer is carried out by means of laboratory tests using conventional methods with a chemical extraction process on jackfruit skin. The raw material used is jackfruit skin (Artocarpus integer). Processing of jackfruit skin into pectin is carried out by several procedures such as extraction using citric acid, purification of pectin with 96% ethanol, FTIR characterization test, density test, viscosity test, shear rate test, and the effect of salinity. The FTIR test showed that pectin was formed after the extraction step, as evidenced by the structure of the pectin-forming groups which was similar to commercial pectin. The deposition of impurity particles contained in the pectin content is evidenced by the lack of optimal pectin to increase the viscosity of water. The increase in viscosity will occur as the concentration of pectin increases. Jackfruit pectin is able to survive in solutions that have high salinity, as evidenced by the higher the salinity of the solution, the thickening process continues.
