Characterization Of Organic Ink From Hydrochar-Based Cellulose Synthesis Of Durian Skin Waste Reinforced By Acasia Substance As Printing Ink Printing

Abstract

Durian peel waste is one of the solid wastes from durian fruit that has not been processed optimally into something more useful. The purpose of this study was to synthesize durian skin waste through several stages combination method they are mechanical processes, chemical processes, and physical processes. The synthesis of hydrochad from cellulose from durian skin waste that has been produced is then mixed with a variety of alcohol with a concentration of 96% reinforced with acacia gum obtained from gum arabic and then tested for characterization to see the potential of hydrochar as a basic ingredient for making organic ink. The analysis carried out is an analysis of the density and viscosity of organic ink produced from hydrochard cellulose from durian skin waste. The results of the characterization of organic ink from durian skin waste indicate that hydrochard as an organic ink material has the potential to be used as a basic material for making organic ink that is environmentally friendly and biodegradable. Organic ink density analysis shows that the organic ink produced is still appropriate and close to the density standard that has been determined by Indonesian national standards. Furthermore, the viscosity analysis also showed the same results, approaching the determined Indonesian national standard (SNI).

Utilization of Palm Oil Waste into Liquid Smoke in Cellulose Commercial Starch Nano Fiber Composite as Antimicrobial Substances in the Manufacturing of Food Packaging

“…Because it allows microbial substances to live and develop in the pores of the bioplastic used in food packaging. This research aims to make food packaging made from biodegradable plastic that is resistant to the growth of microbial substances or bacteria that are not good for health with the help of smoke liquid synthesized from solid palm oil waste [7].…”
