Indonesia produces sweet granadillas (Passiflora ligularis) abundantly. Utilization of this fruit is extensive but not its albedo, eventhough such part of the fruit has been known as rich in fiber. Use of albedo as source for paper production comes to mind since at the other end, paper consumption is keep increasing without being supported by adequate wood resources. This research is a continuation of previous research that focused on paper production from sweet granadilla's albedo by acetosolv. In this research, such method is further modified by producing the pulp without firstly undertaking lipid removal. Addition of certain additives such as chitin, chitosan, and jelly is carried out in order to optimize its physical properties. Without removal of lipid, the resulted paper shows positive improvement of strength, elasticity, and water resistance. Addition of 1% (w/w) chitosan solution in acetic acid at the beginning of pulping process shows that chitosan is homogenously adsorbed and succeeds in improving its mechanical strength. Chitin adsorption is not homogenous, whilst jelly and carrageenan have been failed to be utilized as additives due to their gel properties.
