Abstract

Particleboard is a composite material based on lignocellulose that can be produced from agricultural waste, serving as an alternative to traditional wood products. This study utilized waste from oil palm fronds and empty fruit bunches as raw materials for the production of particleboard. The oil palm fronds were processed into filler particles of varying sizes: 80-mesh, 60-mesh, and 35-mesh. The composition of the raw materials included 50% oil palm frond particles, 15% empty fruit bunch fiber, 20% PVAc adhesive, and 15% epoxy resin. The particleboard was manufactured using a single-punch cold-press process at a pressure of 0.30 MPa for 120 minutes, followed by curing at 150°C for 60 minutes. Various characteristics of the particleboard were tested, including density, water content, thickness swelling, modulus of rupture (MOR), and modulus of elasticity (MOE). The results indicated that the particle size of 80-mesh yielded the best properties, with a density of 0.88 g/cm³, a water content of 5.51.6%, thickness swelling of 1.13%, a MOR of 19.79 MPa, and a MOE of 1.08 GPa. All specimens met the standards set by SNI 03-2105-2006 for density, water content, thickness swelling, and MOR; however, the MOE value did not meet the required standards.

Abstract

Adhesive technology has seen significant advancements in recent years. Compared to welding or threaded joints, adhesives provide a straightforward mechanism for joining material interfaces. Due to practicality allows for the potential development of adhesives with strengths comparable to those of traditional joints. In this study, a modified type of Polyvinyl Acetate (PVAc) adhesive was utilized as a binder for mahogany wood surfaces. The choice of PVAc adhesive is due to its common use in everyday applications, particularly in the woodworking industry. Additionally, this adhesive is relatively safe for both health and the environment. The study examined three types of adhesives: PVAc white adhesive, PVAc yellow adhesive, and a combination of the PVAc white and yellow adhesive. These adhesives were used to bond the wood surfaces, and the bond strength at the interface was evaluated through a flexural test. The results showed that the adhesive strength of white adhesive reached 111 MPa, while the mixed adhesive and yellow adhesive exhibited flexural strengths of 74.2 MPa and 63.4 MPa, respectively. Notably, the presence of white glue was found to enhance the flexural strength of mahogany wood even in the absence of adhesive.

Abstract

Clean and healthy air are major topics around the globe. It is because poor air quality hurts human health and is even responsible for the deaths of millions of people. This work develops exhaust pipes containing filters to reduce the pollutants emitted by motorcycles. There are three pollutant concentrations measured here: CO2, CO, and HC. The measurements were taken before and after the filter system so that the pollutant reduction could be calculated.  The maximum pollutant reduction of the filter system: 6.1 % of CO2, 8.0 % of CO, and 651.0 ppm of HC. The primary mechanism of this filter is the physical trapping of pollutants. When the gas flows through the exhaust pipe, the pollutants in the stream are attached to the filter due to direct contact. This change can be visually observed in the filter color, which darkens after use in the exhaust pipe. However, a limitation of this work is its short-term experiment, which lasted only five minutes, indicating a key area for future research. It is also necessary to have alternative filters that are sustainable and can work properly in high-temperature conditions.
