Utilizing Agricultural Waste: Paper Making from a Mixture of Pineapple Fiber and Rice Straw Fiber

Introduction

The concept of circular economy has gained significant attention in recent years, emphasizing the importance of utilizing waste materials to create economic value products. One such example is the production of paper from plant fibers, which can help reduce the demand for wood pulp and minimize the environmental impact of paper manufacturing. This study explores the potential use of pineapple crested fibers and rice straw fibers in paper making, with a focus on determining the optimal composition of the fiber mixture that produces the highest quality paper.

Background

Pineapple crested fibers and rice straw fibers are two types of agricultural waste that can be utilized in paper making. Pineapple crested fibers are obtained from the pineapple plant, while rice straw fibers are derived from the rice plant. Both types of fibers have been shown to have potential in paper production, but their properties and characteristics differ significantly. Pineapple crested fibers have been found to have high tensile strength and resistance to tearing, while rice straw fibers have been shown to have good absorbency and durability.

Methodology

This study aimed to determine the optimal composition of the pineapple and rice straw fiber mixture that produces the highest quality paper. Six combinations of fiber composition were tested, namely 100%: 0%, 80%: 20%, 60%: 40%, 40%: 60%, 20%: 80%, and 0%: 100%. The paper making process included the following stages:

Fiber Softening: The fibers were softened using a 1.5% NaOH solution at 100 ° C to break down the lignin and pectin in the fibers.
Bleaching: The fibers were bleached using chlorine to remove any impurities and improve their color.
Mixing: The fibers were mixed according to the desired composition to create a uniform blend.
Paper Making: The blended fibers were then formed into paper sheets using a machine.

Results

The results of the study showed that paper with a composition of 40% pineapple fiber and 60% rice straw fiber produced the best quality. This paper had a tensile index of 16,945 nm/g and a torn index of 3,719 x 10-3 Nm2/g, which met the SNI 14-1308-1998 standards. This indicates that a mixture of pineapple and rice straw fibers can produce paper with good strength and endurance.

In comparison, paper made from 100% pineapple fiber had a tensile index of 16,819 nm/g and a torn index of 3,046 x 10-3 nm2/g, while paper made from 100% rice straw fiber had a tensile index of 13,745 nm/g and a torn index of 3,559 x 10-3 Nm2/G.

Discussion

The results of this study have several important implications. Firstly, this research proves that agricultural waste such as pineapple crested and rice straw can be utilized into added value products. Secondly, this research provides information about the optimal composition of the fiber mixture that produces the highest quality paper. Thirdly, this research opens opportunities for the development of the local raw material-based paper industry and environmentally friendly paper production.

Conclusion

This study demonstrates the potential of utilizing pineapple crested fibers and rice straw fibers in paper making. The results show that a mixture of 40% pineapple fiber and 60% rice straw fiber produces the best quality paper, meeting the SNI 14-1308-1998 standards. This research encourages more optimal and sustainable use of agricultural waste and contributes to the development of environmentally friendly paper industries.

Future Directions

Future research can focus on optimizing the paper making process to improve the quality and properties of the paper produced. Additionally, the study can be extended to explore the use of other agricultural waste materials in paper production, such as sugarcane bagasse and corn stalks.
