Styrofoam (Extruded Polystyrene) waste can be used as a soundproofing material. This study aims to determine the effect of the particle composition of Styrofoam and epoxy resin on the performance of soundproofing composites. The composition between Styrofoam particles and epoxy resin is 20:20; 20:30; and 20:50 grams. Sound absorption test using PVC impedance tube 100 cm long, 15 cm diameter, and 5 mm thick. The variation in the placement distance of the composite from the sound source is 25; 50; and 75 cm and was measured using the sound level meter application. This type of test sound uses a single tone in the frequency range of 0-600 Hz which is recorded per 5 seconds. Composite performance analysis is reviewed based on media density, composite morphological characteristics of Image-J software, and sound absorption coefficient values. The results showed that the greater the composition had increased the density value of composite particles accompanied by a decrease in pore area in the composite media which resulted in a sound absorption coefficient of 15.61 dB at a composition of 20:50 with a distance of 25 cm from the sound source.

“…Some starch is extracted from grains such as rice, corn, or wheat, while others are extracted from tubers such as potato and cassava [4]. Many studies have described the use of starch as the matrix of biodegradable foam in conjunction with various types of fiber to create degradable EPS-like foams [1,2,[5][6][7][8][9][10][11][12][13][14][15][16][17][18]. Cassava starch is the cheapest starch in Indonesia when compared to other prevalent starches.…”

Our previous investigation revealed that the addition of water hyacinth fiber (WHF) and polyvinyl alcohol (PVA) enhanced the mechanical properties of cassava starch-based foam. However, the effect of PVA concentration on the mechanical properties of starch foam is still unclear. Therefore, this study examined the effects of various concentrations of PVA on the foam’s quality and production process. Four levels of PVA (0, 1, 2, and 3% w/w) were tested on the mixed dough of cassava starch and 15% of WHF. The foam was made by baking the dough on a thermopressing machine at a temperature of 190 °C for 3 min. The quality level of foams was determined by their physical and mechanical (compressibility, water adsorption, density, color appearance, and biodegradability) properties as well as the practicality of the dough preparation and baking processes. As a result, the addition of PVA significantly affects the mechanical properties and ease of making dough. A higher concentration of PVA contributed to a better mixture of the dough, resulting in a smoother mixing process that led to foams with stronger mechanical properties. Nevertheless, the application of 2% and 3% PVA did not make a significant difference in the mechanical and physical properties. Foam with 2% PVA showed 32 N/mm2 of compressibility, 10% water absorptivity, 12% water content, and good biodegradability, with 87% of the material lost during 30 days of burial in the soil.

“…One such study used the cellulose and starch form banana stems to construct biofoam, which decomposes 90% in 30 days and absorbs 11% of the water in just one minute of soaking (Fatrozi et al, 2020). Sumardiono et al (2021) made biofoam by utilizing cassava flour and corn fiber which produces biofoam with 25.45% water absorption in 1 minute of soaking Study and Characterization of Biofoam From Bagasse (Saccharum officinarum L.) with Chitosan Addition time and decomposes in the soil 20.25% within 14 days. Based on these studies, biofoams are a foam made from natural products such as agricultural waste (Sumardiono et al, 2021;Alexander et al, 2023).…”

The increase in styrofoam waste can cause environmental pollution, therefore efforts are required to reduce the use of styrofoam. One of them is by replacing it with biofoam made from agricultural industry waste such as bagasse because if this garbage is not used, it may cause environmental issues. Bagasse has a potential to be utilized as biofoam. This research aims to extract cellulose from bagasse through delignification and bleaching processes, as well as synthesize and characterize biofoam using cellulose from bagasse with the addition of chitosan variations of 2, 3.5, 5, and 6.5 g. The stages of this research are the extraction of cellulose from bagasse waste with FTIR and XRD analysis, making biofoam and biofoam characterization tests. The results of cellulose extraction from bagasse are O-H, C-H and C-O functional groups that indicate the presence of cellulose. In XRD analysis, the cellulose sample has a crystallinity index of 70.74%. Biofoam based on sugarcane bagasse cellulose with the addition of 2 g chitosan has the best characterization, which has a density of 1.23 g/mL, with a water absorption value of 46.03% at 24 hours immersion and biodegradability of 20.68% for 28 days.
