Abstract

Water hyacinth is a waste in waters that can damage the balance of aquatic ecosystems because of its rapid growth, which can reach 3% in a day. One utilization of water hyacinth waste is to be used as filler material for decorative particleboard. This study aims to look at the physical and mechanical characteristics of particleboard with surface coating treatment using silane coupling agent solution.. Water hyacinth fiber was selected as an alternative filler material for the particle board composite due to its abundant availability and potential fiber properties. The surface of the particle boards was modified using a silane coupling agent (KH550) to enhance the bond quality between components. The water hyacinth powder was first alkalized with NaOH and distilled water (1:5) for 1 hour, then mixed with epoxy resin in a 40:60 weight ratio. The compaction process was carried out using a hydraulic hot press at 2 bar pressure and 50°C temperature for 10 minutes. The resulting particle boards were tested for density, moisture content, water absorption, and thickness swelling. Flexural testing was conducted in accordance with ASTM D790-03, and tensile strength testing followed ASTM D638-14. Surface morphology was observed using a scanning electron microscope (SEM). The results showed that the application of a silane coupling agent improved the bond between the matrix and filler, and the produced particle boards met the quality standards for density, moisture content, water absorption, thickness swelling, flexural strength, and tensile strength.

Abstract

Landfills often become a source of complex environmental problems, especially in urban areas. Poorly managed waste not only poses aesthetic issues but also creates breeding grounds for various organisms that can potentially cause health problems for humans. This study aimed to identify fly species found in a landfill using fresh shrimp bait and to evaluate the effectiveness of the bait in attracting various fly species. The research was conducted at four bait placement points in the landfill area of Mojoarum, Surabaya. Observations were made at 07.00-09.00 and 15.00-17.00. Fresh shrimp bait was used to capture flies, which were then reared and identified based on their morphological characteristics. The results revealed four fly species: Chrysomya megacephala (331 individuals), Musca domestica (74 individuals), Fannia sp. (21 individuals), and Sarcophaga haemorhoidalis (6 individuals). C. megacephala was the most dominant species, indicating that the landfill provides ideal conditions for this species. M. domestica was also found in significant numbers, demonstrating its adaptability to the landfill environment. The fresh shrimp bait proved effective in attracting C. megacephala and M. domestica, but less effective for Fannia sp. and S.  haemorhoidalis. These findings provide important insights into the composition of fly species in landfills and their implications for waste management and environmental health. Improved waste management is necessary to reduce the health risks posed by flies, particularly those species that can act as disease vectors.

Abstract

This study aims to synthesize chalcone derivative compounds (E)-1-(4-Chlorophenyl)-3-(3-Hydroxyphenyl)Prop-2-En-1-One (CX) in alkaline conditions through a stirring method using a magnetic stirrer. 4 chloro acetophenone was reacted with 3 hydroxy benzaldehyde using ethanol p.a as a solvent and 60% KOH as a base catalyst. Furthermore, purification was carried out by recrystallization using ethanol p.a solvent and a yield of 72.67% was obtained. The purity test of the compound was carried out using TLC and melting point tests. Furthermore, the reaction compound was tested for activity as an antidiabetic in silico. In silico studies were carried out to predict the interaction of compounds with proteins (1GFY.pdb). In silico studies show that the cDOCKER energy value obtained by the original COL ligand is higher than the CX compound obtained. The results of the COL ligand docking with the 1GFY protein have a cDOCKER energy value of -49.4051 kcal/mol and have four hydrogen bonds that bind to the important amino acid residues Gly220, Arg221, Ser216 and Asp181. While the docking of the synthetic compound ligand (CX) produces a cDOCKER energy value of -29.293 kcal/mol and shows 3 hydrogen bonds to the important amino acid residues Ser216, Asp181 and Lys120. Based on these results, it is known that the CX compound has the potential to be used as an antidiabetic candidate compound.

Abstract

Increased production in industries tends to increase burden and complexity of waste produced. For this reason, it was necessary to develop materials that have good degradation capabilities and into environmental products. In this research, the MnO2 has been synthesized using the strategy of coprecipitation and reducing agents. The as-synthesized MnO2 is then used for the degradation of methylene blue. The results of this study indicate that different strategy of coprecipitation and reducing agents produce different MnO2 and has unique properties as nano-hierarchical microstructure. Using citric acid as a reducing agent results in a hierarchical structure of α-MnO2 and Mn2O3, while oxalic acid produces a hierarchical structure of β-MnO2 and Mn2O3. To optimize the degradation of Palm Oil Mill Waste which contains a high concentration of pollutants, it still needs to be improved. From the parameters pH, chemical oxygen demand, oil & grease, and total suspended solids, the best degradation efficiency of each parameter was achieved at pH 8.8, 16.3%, 43.5% and 56.6%.

Abstract

The Talang Gulo landfill site in Jambi City does not yet receive clean water services from PDAM, so the community uses dug wells to get water needs. The aim of this research is to analyze the heavy metal content in the well water of residents around the Talang Gulo TPA and determine the effectiveness of using water hyacinth plants (Eichhornia crassipes) in reducing the heavy metal Cadmium (Cd) content in the well water of residents around the Talang Gulo TPA. This research is experimental research and analysis of heavy metal concentrations using Atomic Absorption Spectrophotometry (AAS). Based on the research results, the metal concentrations of Cd, Fe, Cr and Cu in residents' well water were respectively 0.054 mg/L; 1.023 mg/L; 0.062 mg/L; and 0.509 mg/L. The level of contamination/pollution of Cd metal is in the highly polluted category, the highest compared to Fe, Cr and Cu metals. After phytoremediation was carried out using water hyacinth plants for 7, 14, 21 and 28 days, the highest level of effectiveness of water hyacinth plants in reducing Cd metal was obtained on the 21st day, namely 93.61%. So, it can be concluded that water hyacinth plants are very effective in reducing the concentration of Cd metal in well water.
