Making Hydrogels from Durian Skin Cellulose (Durio Zibethinus Murr.) With Aluminum Sulfate Cross-Binding: A Novel Approach to Waste Management and Sustainable Product Development

Introduction

In recent years, there has been a growing interest in developing sustainable and eco-friendly products from agricultural waste. One such waste material is durian skin, which is often discarded and considered a nuisance. However, durian skin contains cellulose, lignin, and starch, making it a potential source of raw material for hydrogel production. Hydrogels are three-dimensional networks of polymer chains that can absorb and retain large amounts of water, making them suitable for various applications, including medical, agricultural, and pharmaceutical industries. In this article, we will discuss the process of making hydrogels from durian skin cellulose, including cellulose isolation steps and the use of aluminum sulfate as a cross binder.

Background

Cellulose is a polymer compound found in plant cell walls, which has hydrophilic properties that make it suitable for use in hydrogel applications. Durian skin, as agricultural waste, is often not utilized optimally, resulting in waste management problems. However, the process of making hydrogel from durian skin not only supports waste management but also produces useful products in various fields. The use of durian skin as a raw material for hydrogel production is a novel approach to waste management and sustainable product development.

Objective

The main purpose of this study is to isolate cellulose from durian skin and bind it with aluminum sulfate to produce hydrogels that have good mechanical and functional properties. The objective of this study is to develop a sustainable and eco-friendly method for producing hydrogels from durian skin, which can be used in various applications.

Method

The process of making hydrogel begins by mixing durian skin powder in sodium hydroxide solution (NaOH). This process includes several important stages:

  1. Alkalization: Durian skin is soaked in NaOH solution to remove lignin and other impurities.
  2. Delignification and Bleaching: This process aims to get pure cellulose that is clean and ready for use.
  3. CMC Synthesis: After getting cellulose, carboxymethylation is carried out by adding sodium monocloroacetate. The resulting CMC is dissolved in distilled water until it reaches a concentration of 4%.
  4. Addition of Aluminum Sulfate: Aluminum sulfate cross-binding solution with varied concentrations (0.3%, 0.4%, and 0.5%) is added to the CMC solution.

After this process, the hydrogel formed was tested to identify functional groups, surface morphology, and elements contained using various analytical techniques, including Fourier Transform Infrared Spectroscopy (FTIR), Scanning Electron Microscopy (SEM), and Energy Dispersive X-Ray Spectroscopy (EDX).

Results

The results of cellulose isolation showed an efficiency of 50%, with a total of 1250 grams of cellulose that was successfully taken from durian skin. CMC synthesis produces 1000 grams of products that meet the desired criteria. Hydrogel examination through FTIR shows that the spectrum produced is in accordance with the specified specifications. In addition, in testing the swelling ratio, gel fraction, and other characterization, hydrogels with aluminum sulfate concentrations 0.4% show the best results compared to other concentrations.

Discussion

The results of this study demonstrate that durian skin is a potential source of raw material for hydrogel production. The use of aluminum sulfate as a cross binder is effective in producing hydrogels with good mechanical and functional properties. The efficiency of cellulose isolation is 50%, which is a significant achievement considering the complexity of the process. The results of FTIR analysis show that the hydrogel produced meets the specified specifications, indicating that the process is effective in producing hydrogels with the desired properties.

Conclusion

From this study, it can be concluded that durian skin is a potential source to produce hydrogels. With the addition of aluminum sulfate solutions at the right concentration, the resulting hydrogel meets various qualitative and quantitative conditions. Utilization of durian skin as a raw material for hydrogel not only provides solutions to waste problems but also opens new opportunities in developing environmentally friendly natural ingredients. This study demonstrates the potential of durian skin as a sustainable and eco-friendly source of raw material for hydrogel production, which can be used in various applications.

Future Directions

This study provides a novel approach to waste management and sustainable product development. Future studies can focus on optimizing the process of cellulose isolation and CMC synthesis to improve the efficiency of hydrogel production. Additionally, the use of aluminum sulfate as a cross binder can be explored further to develop new hydrogel products with improved mechanical and functional properties.
