Abstract

Aim: This study aims to determine the potency of horsetail plant to remove heavy metal concentration. Methodology and Results: Data was obtained from fifty-four (54) horsetails which were divided into three batches of 12, 18, and 24 plants respectively. Furthermore, the experimental method with the subsurface flow system treatment was used with two samplings for seven days. The results showed that the first, second and third batches gave a 6.83%, 10.28%, and 16.26% impact on reducing concentration of Fe respectively with an approximate average of 11%. Therefore, the detention time of the leachate constructed wetland reactors significantly reduced the Fe contaminant. Conclusion, significance, and impact of study: This research provides a solution to mitigate the environment by adopting the accumulator of Horsetail plants (Equisetem hyemale) in the constructed wetlands reactor experiment. From the three reactors approximately 0.03 mg/L of heavy metal iron was removed after a seven day run. Therefore, horsetail plant showed a positive impact in reducing environmental pollution, a trend adoptable in wastewater and leachate treatment technology in Indonesia.

Abstract

Roof tiles play a vital role in the construction industry hagoslot by providing protection from the sun's heat and rain. The quality of roof tiles largely depends on the materials used and the manufacturing process, as these factors significantly affect the tiles' mechanical properties. Kangkung pagar (Ipomoea carnea) is one type of alternative natural fiber material that can be utilized in the creation of composite materials. This study aims to explore the potential of Ipomoea carnea powder as an alternative material for producing polymer roof tiles, as well as to examine how variations in the composition of powder and sand influence the mechanical properties of these tiles. The method for producing roof tiles is based on powder metallurgy. The composition of the powder and sand used varies in the following ratios: 10% powder to 50% sand, 20% powder to 40% sand, and 30% powder to 30% sand. Additionally, a fixed composition of 30% polyester resin and 10% asphalt is used. The initial process involves mixing the materials according to these predetermined ratios. The resulting mixture is then molded and compacted under a pressure of 200 kg/cm². Characterization of the mechanical properties includes proximate analysis, calculation of porosity and density, flexural strength testing, and hardness testing.The study's results indicated that the properties of polymer roof tiles are significantly influenced by the composition of the powder and sand used during their manufacture. The findings revealed a porosity value of 0.209%, a density of 0.994%, a flexural strength of 2.270 MPa, and an optimum hardness of 19.1 BHN. The addition of 10% powder increased the hardness value by only 0.4% while decreasing the flexural strength by 0.5%. Overall, the use of Ipomoea Carnea powder was not effective in enhancing the mechanical properties of the polymer roof tiles, as both the flexural strength and hardness values remained below those of commercially available polymer roof tiles.

Abstract

Heat exposure can influence the changes in hardness and flexural strength of composites made from eggshell particles and bamboo fibers. The composite samples were prepared through cold compaction at 5 MPa for 2 hours. The materials were combined based on the following volume fractions: 50% epoxy resin, 10% alumina, 10% graphite, 5% zinc oxide (ZnO), and a 25% mixture of eggshell particles and bamboo fibers. The composite samples were then heated to 200°C for 1 hour. The final step involved curing, which required heating the samples in an electric oven at 150°C for 1 hour. Using a weighting method, the composite containing 25% eggshell particles achieved the optimal result, with a multi response performance index (MRPI) of 42.43. This composite exhibited hardness, modulus of elasticity (MOE), modulus of rupture (MOR), and strain values of 70.24 Shore D, 37.65 MPa, 8.58 MPa, and 0.78%, respectively. Conversely, the sample with 25% bamboo fiber and no eggshell particles demonstrated the highest flexural strength at 12.06 MPa, while the sample containing 25% eggshell particles recorded the highest hardness of 70.24 Shore D.

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.
