Abstract

The objective of this work is to explain the harms of plastics present in water as they affect humans and relations. Plastics are major polymers in contemporary dealings of human endeavors. They are synthesized through the addition or condensation of monomer units and serve humans with their distinguishing benefits such as the ability to be processed to various things by molding. Extensive uses of plastics show that all human activities use plastic for one purpose or the other. Water utilized by humans is in constant contact with plastics indicating a probable pollution that affects human health. This paper reviews the role of water in the body (systems), types of plastics, types of plastics, harm to animals, concerned behaviors of plastics, harmful contents, and management. There is a need for enlightenment, and strict laws (policies).

Abstract

Biosynthesis of gold nanoparticles using banana peels is considered more economical and has been proven to produce gold nanoparticles that have various applications in the medical field. Therefore, the production of gold nanoparticles needs to be developed on an industrial scale. This paper aims to determine the feasibility of a gold nanoparticle biosynthesis project using banana peels on an industrial scale. The economic evaluation method uses an analysis of several economic evaluation parameters such as GPM (Gross Profit Margin), BEP (Break-Even Point), CNPV (Cumulative Net Present Value), PBP (Payback Period), and PI (Profitability Index). The results show that on an industrial scale, it is assumed that the amount of AuNP production in one year is 120 L. The total price required for production in one year is 3,125,204.84 USD with annual sales of 3,240,000 USD so that the total price is 114,795.16 USD per year. Under ideal conditions, the PBP analysis shows that the project will have a profit in the 3rd year, and the PI analysis shows that the initial capital costs can be covered since the 4th year. The results of the analysis in some non-ideal conditions indicate that project losses will occur. Based on the economic evaluation, it can be concluded that the production of industrial-scale gold nanoparticles by biosynthetic methods using banana peels can be carried out with anticipation of losses that will occur due to changes in some ideal conditions.

Abstract

This research aims to describe student activities during the application of project-based worksheets, analyze scientific performance, and analyze the characteristics of the resulting kaolin soap with the addition of kefir curd. The research method used is pre-experimental with a one-shot case study research design. The research subjects were 34 students of XI grade in an Islamic school in Bandung, Indonesia. The results of the research show that the percentage of student activity during the application of the worksheet is 87 in the very good category. The highest average score was 94 with a very good category at the stage of carrying out the research. The students' scientific performance ability in applying worksheets reached 86 in the very good category. The highest average score is 92 with the very good category found in the indicator for interpreting data. The results of the characterization of the kaolin soap produced follow Indonesian National standard No. 3532:2021 with a pH value of 10, the foam stability values respectively from highest to lowest are 89, 85, 83, 60, and 50%. Based on the organoleptic test, the soap has a solid texture and smells like clay with a bone-white color. This shows that the implementation of project-based worksheets can be carried out well

Abstract

In critical care, the co-administration of intravenous drugs often leads to physical incompatibilities, resulting in harmful precipitates. This study evaluated the nature of drug-induced precipitation in terms of size, shape, and quantity. Twelve drugs previously reported to be incompatible were tested with infusion fluids. Particle detection was conducted using an Olympus CX41 microscope with a 1 µm detection limit, enhanced by darkfield microscopy for better sensitivity. Particle size was analyzed using Feret’s diameter via the Optilab imaging system. Precipitates ranged from 5–150 µm, with smaller particles (<10 µm) seen in furosemide and subvisible particles (10–50 µm) in cefotaxime, chloramphenicol, and paracetamol. Visible particles were noted in acyclovir, ampicillin, meropenem, phenobarbital, and phenytoin. Most macro-precipitates were acicular, while micro-precipitates tended to be irregular. Particle counts ranged from 80 to 2,000 particles/mL. The findings highlight the clinical risk of particulate contamination due to drug incompatibilities, emphasizing the need for careful medication management.

Abstract

Recovering materials from waste is a viable solution for managing paint-related organic solvent waste. This study focuses on the extraction of organic solvents from paint residues, which contain resins and pigments, to produce a renewed solvent. The method selected for recovery was distillation, which was used for optimizing the separation conditions for the solvents from their waste impurities. Using a batch distillation apparatus with a 30-L capacity, experiments were conducted at varying operating temperatures (120, 130, 140, 150, and 160°C) under a consistent vacuum pressure of 0.9 bar. The optimal results indicated that at 160°C and a vacuum pressure of 0.9 bar, a naphtha solvent with a 66.37% recovery rate was achieved at 19.91 L and an initial feed volume. This method of solvent recovery not only holds promise for waste reduction but also contributes significantly to environmental protection by minimizing pollutants.

Abstract

The Balanites aegyptiaca is an important tree found in some African countries. This study aimed to assess the seeds of the Balanites aegyptiaca physicochemically and phytochemically. pH, Moisture, ash, protein, and lipid contents of Balanites aegyptiaca seeds are 5.8, 2.10%, 5.6%, 17.5%, and 10.7%, respectively. The mineral elements analysis showed that the Balanites aegyptiaca is rich in calcium (247.4 mg/100 g), potassium (140 mg/100 g), sodium (30 mg/100 g), magnesium (24.6 mg/100 g), iron (8.50 mg/100 g) and zinc (5.50 mg/100 g). The result suggests that the seeds of Balanites aegyptiaca fruits could contribute greatly towards meeting the human nutritional requirement for normal growth. The presence of several phytochemical compounds showed high therapeutic potential of Balanites aegyptiaca and it can take for medicinal purposes after determining the seeds pharmacologically.

Abstract

This study explores the Lewis acid/base interactions of divalent metal ions—copper (II), lead (II), and mercury (II)—with Lewis bases 2-naphthol and caffeine in an ethanol solvent. Utilizing the method of continuous variation, absorbance data were analyzed to understand these interactions. Absorbance data analyzed through Job's plot revealed distinct interaction patterns. For the copper (II) system, the Job's plot did not exhibit a maximum, indicating a lack of significant cooperative interaction, with absorbance values fluctuating without a clear pattern. In contrast, the lead (II) and mercury (II) systems demonstrated clear maxima with both 2-naphthol and caffeine, evidencing cooperative interactions. Specifically, the Job plot for lead (II) with 2-naphthol peaked at an absorbance of 1.25 at a mole ratio of 1:1, and for mercury (II) with caffeine, a maximum absorbance of 1.40 was observed at the same stoichiometry. These results indicate a 1:1 stoichiometry for the adducts formed, suggesting that the interactions of these metal ions with the bases can be described by the Eigen-Wilkins mechanism. This mechanism may thus account for the adduct formation involving the class B Lewis acids studied in a non-aqueous medium, highlighting a distinctive aspect of their chemical behavior.

Abstract

In the present paper, the electrodynamic and photovoltaic devices were analyzed. The methods used were modeling of accumulated loads, differential geometry for Solitonials, and generalized Piezo-electricity. Models for dynamic capacitors in the WFB are derived. The analysis is based on observations and experimental results. The experiment was done by providing AC-power background and attaching an NPN-Sun-Catcher. Then, the designed equipment was evaluated in terms of the one-way elasto-electricity and photovoltaic process. The realizations of this designed equipment are suitable for educational purposes. And, this equipment with small encapsulated components operating in higher-power applications can be implemented as realistic solutions for solar-related uses.
