Manufacture and Characterization of Acoustic Boards from a Mixture of Rattan Skin Fiber and Acetate Polyvinyl Adhesive

Introduction

The use of acoustic materials in various industries, such as construction and interior design, has become increasingly important in recent years. Effective acoustic materials are needed to reduce noise and create comfortable spaces. In this study, we focus on the manufacture and characterization of acoustic boards from a mixture of rattan skin fiber and acetate polyvinyl adhesive (PVAC). The main objective of this research is to develop a sustainable and effective acoustic material that meets the technical needs of the industry.

Materials and Methods

The materials used in this study include rattan skin fiber and PVAC adhesive. The rattan skin fiber was obtained from local sources, while the PVAC adhesive was purchased from a reputable supplier. The mixture of rattan skin fiber and PVAC adhesive was prepared in various proportions, ranging from 80% to 100% rattan fiber composition. The specimens were then tested for their sound absorption properties using the impedance tube method.

Results

The results of the study showed that the maximum noise reduction coefficient (NRC) value of the acoustic material reached 0.9, obtained from specimens with 90% rattan fiber composition and 10% PVAC adhesive. This value is in accordance with the standard set by ISO 11654, which requires a minimum NRC value of 0.8 for sound absorbent materials. The αW value of the acoustic material ranged from 0.15 to 1, which is also in accordance with the standard.

In addition to the sound absorption properties, the density of the acoustic material was also tested. The results showed that the density of the material ranged from 0.486 to 1,021 g/cm³, which is within the range set by the SNI standard 01–4449-2006. The tensile strength and flexural strength of the acoustic material were also tested, and the results showed that the tensile force ranged from 5.27 to 42.66 MPa, while the flexible force ranged from 12.63 to 19.82 MPa.

Discussion

The results of the study showed that the acoustic material produced from the mixture of rattan skin fiber and PVAC adhesive meets the technical requirements set by the industry. The high NRC value of the material indicates that it is effective in absorbing sound waves and reducing unwanted sound reflections. The density of the material is also within the range set by the standard, indicating that it is stable and durable.

The tensile and flexible strength of the acoustic material also indicate that it is able to withstand the load and pressure without damage. This makes it suitable for use in various applications, ranging from meeting rooms to recording studios. The use of rattan skin fiber in the production of acoustic material also contributes to environmental sustainability, as rattan is a renewable resource.

Conclusion

In conclusion, the manufacture and characterization of acoustic boards from a mixture of rattan skin fiber and acetate polyvinyl adhesive has been successfully carried out. The results of the study showed that the acoustic material produced meets the technical requirements set by the industry, including the sound absorption properties, density, and tensile and flexible strength. The use of rattan skin fiber in the production of acoustic material also contributes to environmental sustainability.

Recommendations

Based on the results of the study, the following recommendations are made:

The use of rattan skin fiber in the production of acoustic material should be continued, as it contributes to environmental sustainability.
The proportion of rattan fiber composition in the mixture should be optimized to achieve the highest NRC value.
The density of the material should be further optimized to achieve the highest stability and endurance.
The tensile and flexible strength of the material should be further tested to ensure that it can withstand the load and pressure without damage.

Future Research Directions

Future research directions include:

The use of other natural ingredients in the production of acoustic material, such as bamboo or sugarcane.
The optimization of the proportion of rattan fiber composition in the mixture to achieve the highest NRC value.
The development of new acoustic materials that are more sustainable and effective.

Limitations of the Study

The limitations of the study include:

The use of a limited number of specimens in the study, which may not be representative of the entire population.
The use of a single type of PVAC adhesive, which may not be representative of all types of PVAC adhesives.
The lack of testing of the acoustic material in real-world applications, such as meeting rooms or recording studios.
