Abstract

Wood Plastic Composite (WPCs) in this study is made from oil palm empty bunches (OP-EFB) which function as fillers and plastics that function as a matrix. This study aims to analyze the effect of the comparison of the composition of the empty fruit bunches of oil palm and HDPE plastic based on the physical and mechanical properties of WPCs. Comparison of the composition of OP-EFB and plastics used in this study were (60:40, 55:45, 50:50, 45:55, 40:60) with the addition of maleic anhydride (MAH) coupling agents and benzoyl peroxide (BPO) initiators. The board manufacturing process is carried out at a temperature of 170oC by pressing for 10 minutes. The results showed that the difference in the ratio of OP-EFB composition and HDPE plastic had a significant effect on the WPCs produced. The optimum ratio of OP-EFB fibers and HDPE plastics is the ratio of 45:55 with the density, water absorption, fracture strength (MOR), parallel surface compressive strength, surface perpendicular compression strength of 0.83 g / cm³, 0.21%, 180.86 kg / cm², 200.48 kg / cm², 47.13 kg / cm². The overall physical and mechanical properties of the WPC are in accordance with SNI 8154-2015 standards regarding wood-plastic composites.

Abstract

This study aims to determine the effect of adding stearic acid (SA) to a bioplastic mixture of cassava starch (CS) and polylactic acid (PLA). The bioplastic was produced using a solvent casting method. The addition of SA can affect the mechanical properties of the film. The maximum tensile strength of the film increased from 5.12 MPa (without SA) to 7.61 MPa (5% SA). The same trend also applies to the Young's modulus and elongation at break, which increased from 25.45 MPa and 20.17% to 35.02 MPa and 21.64% after the addition of 5% SA. This improvement in mechanical properties is supported by the compatibility of PLA and CS due to the optimal presence of SA. These findings prove that SA is an effective compatibilizer in improving the mechanical properties of PLA and CS-based bioplastics. The resulting film products have the potential to be used as environmentally friendly packaging materials that are competitive with synthetic materials such as Low-Density Polyethylene (LDPE) and Ethylene Vinyl Acetate (EVA).

Abstract

Sago liquid waste contains high levels of carbohydrates and has potential as a fermentation medium for bacterial cellulose production. However, its nutritional content requires enhancement by supplementing it with tea waste to achieve optimal yields. This study investigated the effect of varying tea waste additions on the characteristics of bacterial cellulose produced from kombucha fermentation based on sago liquid waste. The research method used a completely randomized design with five treatments (2, 4, 6, 8, and 10 g of tea dregs) and three replications. The observed parameters included yield, thickness, moisture content, cellulose content, and Fourier Transform Infrared (FTIR) spectroscopy. The results showed that increasing tea waste levels significantly affected all parameters (p < 0.05). The best treatment (10 g) resulted in a yield of 18.21%, a thickness of 13.47 mm, a moisture content of 47.57%, and a cellulose content of 52.43%. FTIR spectral analysis confirmed the characteristic peaks of bacterial cellulose, indicating the presence of crystalline β-1,4-glucan structures. The identification of cellulose type I is significant because it represents the native crystalline form of bacterial cellulose, which is associated with high mechanical stability, strong hydrogen bonding, and potential suitability for biopolymer applications. This study demonstrates that tea waste is an effective nutrient supplement that enhances the quality and quantity of bacterial cellulose derived from kombucha fermentation of sago liquid waste.

Abstract

The development of sustainable, high-performance energy storage systems is crucial for addressing the challenges associated with renewable energy integration and the limitations of conventional lithium-ion batteries. This study investigated the potential of an innovative electrolyte membrane for aluminum-air batteries, incorporating carbon quantum dots (CQDs) derived from rice husk charcoal and carbon nanotubes (CNTs) within a polyvinyl alcohol (PVA) matrix. CQDs were synthesized using a microwave-assisted technique, and CNTs were added to enhance the structural and conductive properties of the membranes. Three distinct membrane compositions were prepared: a base solution of PVA, HCl, and glycerol; a base solution with CQDs; and a base solution with CQDs and CNTs. Fourier Transform-Infrared (FT-IR) spectroscopy revealed enhanced intermolecular interactions and successful integration of the carbon nanomaterials within the polymer network. X-ray diffraction (XRD) analysis indicated a reduction in crystallite size from 11.27 nm (base membrane) to 9.65 nm (–14.36%) with CQDs and further to 8.29 nm (–26.47%) with CQDs + CNTs, suggesting improved amorphous characteristics that reinforce the membrane structure and facilitate ionic conductivity. Electrochemical impedance spectroscopy (EIS) demonstrated an increase in ionic conductivity from 4.98501 mS/cm (base membrane) to 5.51837 mS/cm with CQDs and 6.35292 mS/cm (+27.4%) with CQDs + CNTs. These findings highlight the synergistic effect of CQDs and CNTs in optimizing the ion migration pathways and charge transport within the electrolyte membrane. The utilization of rice husk charcoal as a precursor for CQDs aligns with sustainable practices and promotes the use of renewable resources. This study presents a promising approach for the development of advanced electrolyte membranes for aluminum-air batteries, contributing to efficient, environmentally friendly, and cost-effective energy storage solutions.

Abstract

The excessive and widespread usage of single-use plastics has led to a growing concern over the accumulation of non-biodegradable waste in natural environments, posing a serious threat to global ecosystems. Incorporating agricultural residues into polymer composites as reinforcements presents a sustainable alternative, offering benefits such as low cost, ease of processing, reduced environmental impact, lightweight characteristics, and biodegradability. This research investigates how the particle size of Delonix regia (D.regia) seed waste influences the physico-mechanical properties of a composite made from waste low density polyethylene (wLDPE). The study found that increasing the particle size of the filler led to a gradual reduction in tensile strength, elongation at break, flexural strength, and density of the composite by 15.75 %, 75.93 %, 24.08 % and 14.08 % respectively. Conversely, larger filler particles enhanced the composite’s hardness and impact resistance by 56.16 % and 76.07 % respectively. Additionally, water absorption increased with particle size, with the highest uptake observed in composites containing the largest particles and lowest in composites containing smallest particles.

Abstract

The increasing demand for lightweight, high-performance, and environmentally sustainable materials in the automotive industry has accelerated the adoption of adhesive bonding as an alternative to conventional joining techniques such as welding and mechanical fastening. Reliable prediction of stress distribution and debonding behavior in adhesively bonded composite–metal joints is therefore essential to ensure structural integrity under service loading. This study presents a comprehensive computational and experimental investigation of the tensile stress behavior of adhesively bonded single-side strap joints (ABSSSJ) formed between steel and hybrid sisal–glass reinforced high-density polyethylene (HDPE) composites for automobile side body panel applications. The hybrid composite adherend was modeled as an orthotropic laminate with a ([0°/+45°/90°/–45°/0°]) stacking sequence, while the adhesive layer was characterized using different epoxy systems (Araldite 2020, Araldite 2015, and AV138) with thicknesses ranging from 0.12 to 1.0 mm and elastic moduli between 1.85 and 6 GPa. An analytical variational method was employed to evaluate shear and peel stress distributions, and the results were verified using a cohesive zone model (CZM)-based finite element approach to simulate crack initiation and progressive debonding. Experimental tensile and shear tests were conducted to validate the numerical predictions. The results indicate that an adhesive thickness of approximately 0.75 mm provides an optimal balance between load transfer efficiency and stress reduction at the overlap edges. The numerical and analytical predictions exhibited strong agreement with experimental measurements, with a maximum deviation below 6%. The validated results demonstrate that hybrid sisal–glass reinforced HDPE composites, when combined with appropriate adhesive and joint design, offer a promising, lightweight, and sustainable solution for automotive side body panel structures.

Abstract

The development of active pharmaceutical packaging based on biodegradable materials is an important strategy to reduce dependence on single-use plastics and their environmental impact. Polyvinyl alcohol (PVA) is a potential biodegradable polymer, but it has limitations in terms of exposure to ultraviolet (UV) radiation and microbial contamination. This study aims to develop a modified PVA film with methanol-soluble phenolic extract of Spatholobus littoralis Hask as active pharmaceutical packaging with UV protection, antioxidant, and antibacterial functions. The phenolic extract was obtained through a maceration method using methanol as a solvent, while the PVA film was fabricated using the solution casting technique. The PVA film was modified with varying concentrations of phenolic extract of 0, 1.25, 2.5, and 5wt% (PPE0, PPE1.25, PPE2.5, and PPE5), then evaluated for its UV protection properties, antioxidant activity, and antibacterial activity. The results showed that the addition of S. littoralis phenolic extract was able to increase the ability of PVA films to block UV radiation completely (100%) in the 200–400 nm wavelength range. Antioxidant activity testing using the DPPH method showed an increase in free radical scavenging ability as the concentration of phenolic extract increased. In addition, the modified PVA film showed significant antibacterial activity against Staphylococcus aureus and Escherichia coli. These findings indicate that S. littoralis Hask phenolic extract has potential as a natural bioactive agent in the development of environmentally friendly and multifunctional active pharmaceutical packaging, with dual protection capabilities against UV degradation and microbial contamination. This research makes an important contribution to the development of sustainable pharmaceutical packaging materials based on renewable natural resources.

Abstract

The use of renewable natural fibers as reinforcements in biodegradable matrices has been boosted by the development of sustainable polymer materials. The purpose of this work is to examine the properties of bio-composites made of polyvinyl alcohol (PVA) reinforced with micro-cellulose fibers that are isolated from the underused plant resource Paederia foetida (MSPf). After retting and alkaline and bleaching treatments, micro-cellulose was obtained and added to PVA at a weight percentage of 5% utilizing the solution casting technique. The biocomposites' mechanical, thermal, water absorption, and morphological characteristics were assessed. When MSPf was added, PVA's tensile strength rose from 20.69 MPa to 23.10 MPa, and its elastic modulus increased dramatically, suggesting better stiffness and efficient stress transfer. The improvement is ascribed to the hydroxyl groups of PVA and cellulose having strong hydrogen bonds and good interfacial adhesion. Due to limited polymer chain mobility, elongation at break decreased, but the composite showed better structural integrity. After 36 h, water absorption attained an equilibrium value of 1.461%, indicating the creation of a compact fiber-matrix network. When compared to clean PVA, thermogravimetric analysis showed better thermal stability, and SEM verified strong interfacial compatibility and homogeneous dispersion. These results show that micro-cellulose derived from Paederia foetida is a viable sustainable reinforcement that can improve the performance of bio-composites based on PVA.
