Introduction

Pineapple leaves are a common waste product in many agricultural areas, including the North Tapanuli region in Indonesia. These leaves are rich in cellulose, a biodegradable and renewable resource that can be used to produce various products, including cellulose nanocrystalline (NCC). NCC is a highly valued material due to its unique properties, such as high density, strength, and ability to form strong tissues. In this study, we aim to synthesize NCC from pineapple leaves using the acid hydrolysis method and investigate its effects on the quality of recycled paper.

Background

Pineapple leaves are an abundant waste product in many agricultural areas, particularly in the North Tapanuli region in Indonesia. These leaves are rich in cellulose, a biodegradable and renewable resource that can be used to produce various products, including cellulose nanocrystalline (NCC). NCC is a highly valued material due to its unique properties, such as high density, strength, and ability to form strong tissues. The production of NCC from pineapple leaves offers a sustainable and environmentally friendly approach to reducing waste and promoting the development of more efficient and sustainable technology.

Materials and Methods

The extraction process of NCC from pineapple leaves was carried out using the acid hydrolysis method. This method involves the use of sulfuric acid to break down the amorphous fractions in cellulose, resulting in the production of NCC. The extraction process was carried out for 60 minutes and continued with ultrasonication. The resulting NCC was then characterized using transmission electron microscopy (TEM) and X-ray diffraction (XRD) to determine its structure and crystallinity.

Results

The results of the TEM analysis showed that the NCC extraction was successfully carried out, as evidenced by the rod-shaped structure produced. The XRD analysis showed a crystallinity level of 78% and a crystalline size of 2.35 Nm. These results indicate that the NCC produced from pineapple leaves has a high degree of crystallinity and a well-defined structure.

Effects of NCC on the Quality of Recycled Paper

The NCC obtained from pineapple leaves was mixed into used newspaper pulp with various ratios, namely 0%, 1.5%, 3%, 5%, and 8%. The results showed that the addition of NCC improved the mechanical properties of paper, particularly tensile strength. This is caused by the interaction of hydrogen bonds between NCC and pulp. The maximum increase in tensile strength was achieved by adding 5% NCC.

Additional Analysis and Explanation

The quality of paper is strongly influenced by the raw material. By using NCC from pineapple leaves, the paper recycling process can be increased, as the NCC has superior mechanical properties. Nanocrystalline cellulose is known for its high density and ability to form a strong tissue, which can strengthen the structure of paper. When the NCC is added to the paper pulp, the physical and chemical interaction between the paper fiber and the NCC serves to increase cohesion and strengthen the bonds between fiber.

Furthermore, the use of pineapple leaves as a source of cellulose not only provides economic benefits through reducing waste, but also has a positive impact on the environment. The use of agricultural waste in the production of high-quality paper raw materials shows a sustainable approach that is in line with the principles of the circular economy. This has the potential to open new opportunities in the paper industry, especially in areas rich in agricultural waste.

Conclusion

In conclusion, this study shows that the use of NCCs produced from pineapple leaves can significantly improve the quality of recycled paper, and offer an environmentally friendly and sustainable method in the paper industry. The use of abundant local resources not only reduces the environmental impact of waste, but also helps in the development of more efficient and sustainable technology.
