THE EFFICACY OF CARICA PAPAYA STEM LEAVES AS AN ALTERNATIVE MATERIAL FOR PAPER

Abstract

Paper production has become one of the major issues faced by the industry. The rate of deforestation continues to increase due to the manufacturing of commercial paper sheets, which also contributes to pollution. To address this issue, the researchers aimed to develop non-wood paper using Carica papaya stem leaves in order to reduce dependence on conventional paper production materials. This study employed a quantitative method with an experimental research design. The paper production process involved several procedures. Papaya stems were collected, cut, and soaked in a basin, after which they were rinsed and boiled with water and sodium hydroxide. The boiled Carica papaya stems were then ground to achieve a pulpy consistency, and the pulp was bleached using chlorine. The mixture was placed in a basin, mixed with water, and evenly distributed using a deckle on a flat surface lined with cotton fabric. A sponge was used to absorb excess water, and the sheet was set aside in an open area to dry until the paper was formed. The results indicated that the physical properties of paper produced from papaya stem leaves differed from those of commercial paper. The papaya-based paper exhibited a distinct texture due to differences in fold lines. During folding tests, paper made from papaya stem leaves broke more easily compared to traditional paper. Overall, papaya stem paper demonstrated lower tear endurance but showed comparable performance to commercial paper in terms of fire resistance and water absorption. The findings demonstrate that Carica papaya stems have the potential to be used as a raw material for paper production. Utilizing papaya stem leaves as an alternative material may contribute to reducing reliance on wood-based paper and support more sustainable paper manufacturing practices.
