Introduction

In the midst of increasingly urgent environmental issues, the search for innovative solutions to reduce the use of disposable plastic is very important. One interesting approach is the use of water hyacinth and chitosan fiber as raw material for making environmentally friendly packaging. The use of biodegradable materials has gained significant attention in recent years due to the growing concern about the environmental impact of plastic waste. Water hyacinth and chitosan fiber are two promising materials that can be used to create biodegradable plastics.

Background

Water hyacinth (Eichhornia crassipes) is a water plant that thrives in various regions and can be found in ponds, lakes, and rivers. It is known to cause problems in waterways due to its rapid growth and ability to block water flow. However, this plant can also be a source of sustainable raw materials. Chitosan, on the other hand, is a derivative of chitin obtained from sea animal shells. It has biodegradable and non-toxic properties, making it an ideal material for creating biodegradable plastics.

Methodology

In a study, a biodegradable plastic composite was made from water hyacinth and glycerol with chitosan modified as plasticizer. The manufacturing process began by mixing water hyacinth fibers, chitosan, and rice flour in a certain ratio. The mixture was stirred at a speed of 50 rpm and temperature between 90-100 ° C for 30 minutes. After that, 10 ml of glycerol was added and the mixture was stirred again at the same temperature for 30 minutes. This process ended with a plastic printing which was then heated in an oven at 60-70 ° C for 24 hours. Mechanical and physical tests were carried out to measure the properties of test objects such as tensile strength, elasticity, density, and biodegradation.

Results

The results showed that the optimal tensile strength was achieved at a value of 3.88 MPa with a variation of chitosan 30%. The best elasticity was measured at 10.691% also in the same variation in chitosan. Meanwhile, the optimal density reached 1,543 g/mm³ on the chitosan variation of 40%. In terms of biodegradation, when the sample was soaked in water for 7 days, the biodegradation rate reached 91.7% with a 40% chitosan variation, and increased to 93.3% after 14 days with the same variation.

Analysis and Benefits of Utilization of Water Hyacinth and Chitosan

Utilization of water hyacinth as an alternative raw material in the plastic industry has many advantages. Water hyacinth is a water plant that thrives and can be found in various regions, making it a source of sustainable raw materials. In addition, the processing and utilization of water hyacinth can help overcome the problem of blockage of waterways that are often caused by the growth of this plant.

Chitosan, which is a derivative of chitin obtained from sea animal shells, also has biodegradable and non-toxic properties. When combined with water hyacinth, chitosan provides additional strength and improves the physical properties of the resulting plastic composite. This shows the potential to replace conventional plastic made from petroleum.

Conclusion

The development of environmentally friendly packaging from this combination not only provides solutions to disposable plastic problems, but also supports the principle of circular economy by utilizing sustainable and decomposed resources. In addition, this product can also be a special attraction in the market, especially among consumers who care about the environment.

Future Directions

The success in this study shows the importance of collaboration between technology, sustainability, and innovation in creating products that are not only environmentally friendly but also meet the quality standards needed in the packaging industry. By continuing to explore local potential such as water hyacinth and develop the right technology, we can create a greener and sustainable future.

Recommendations

Based on the results of this study, the following recommendations can be made:

Further research is needed to optimize the composition of water hyacinth and chitosan to achieve better physical properties.
The development of large-scale production of biodegradable plastics from water hyacinth and chitosan is necessary to meet the increasing demand for environmentally friendly packaging.
Collaboration between industries, academia, and government is essential to promote the use of biodegradable plastics and reduce plastic waste.

Limitations

This study has several limitations that need to be addressed in future research. These include:

The use of a small sample size, which may not be representative of the larger population.
The lack of control over the processing conditions, which may affect the physical properties of the resulting plastic composite.
The need for further research to optimize the composition of water hyacinth and chitosan to achieve better physical properties.

Future Research Directions

Future research directions include:

Investigating the use of other biodegradable materials, such as cornstarch and sugarcane, as alternatives to water hyacinth and chitosan.
Developing new technologies to improve the production efficiency and reduce the cost of biodegradable plastics.
Conducting life cycle assessments to evaluate the environmental impact of biodegradable plastics and compare them to conventional plastics.

Conclusion

In conclusion, the utilization of water hyacinth and chitosan fiber as raw material for making poly lactic acid as environmentally friendly packaging is a promising approach to reduce plastic waste and promote sustainability. Further research is needed to optimize the composition of water hyacinth and chitosan, develop large-scale production, and promote the use of biodegradable plastics.
