Abstract

Purpose of the study: The main objective of this study is to identify students' knowledge of Occupational Safety and Security. Methodology: One hundred and eighty three (183) students of the Chemistry Education study program, Faculty of Tarbiyah and Teacher Training, Syarif Hidayatullah State Islamic University, Jakarta, participated in answering the test on Occupational Safety and Security. This test was developed based on three Occupational Safety and Security indicators, namely storing, general work procedures (handling), and disposal of hazardous chemicals. Main Findings: Based on data analysis, it was found that on average students have insufficient knowledge about the three Occupational Safety and Security indicators (38%). In detail, the indicator for storing is 33%, general work procedures is 34%, and the last is for disposing of hazardous chemicals is 47%. The results obtained have not been able to show students' general knowledge about Occupational Safety and Security, but can be an early warning to realize the importance of Occupational Safety and Security knowledge for students when experimenting in a chemistry laboratory. Novelty/Originality of this study: This study examines the level of knowledge of Chemistry Education students regarding the principles of (Occupational Safety and Security) in the laboratory, which is an innovative step in increasing awareness and implementation of safety protocols in practical learning.

Abstract

Purpose of the study: The aim of this study was to produce SnO2 nanoparticles by electrochemical method using tin metal and hydrochloric acid as electrolyte solution. Methodology: Synthesis of SnO₂ nanoparticles was carried out using an electrochemical method with tin electrodes and HCl solution. Variations in potential (10–100 V) and HCl concentration (0.005–0.06 M) were observed for optimization. Characterization using UV-Vis, FTIR, XRD, and Zeta Sizer showed that this method was effective in producing SnO₂ nanoparticles with crystal structure, composition, and size distribution that could be optimized. Main Findings: This study successfully synthesized SnO₂ nanoparticles from tin metal using an electrochemical method with HCl solution. The optimum potential for electrolysis was 60 V, with a HCl concentration of 0.06 M producing the largest nanoparticles (83.11 nm) at a wavelength of 207 nm and an absorbance of 3.068. XRD characterization showed a diffraction pattern according to the SnO₂ standard, while FTIR confirmed the Sn–O vibration at 580 cm⁻¹. Novelty/Originality of this study: The characterization results show a correlation between HCl concentration with nanoparticle size and absorbance wavelength, which provides new insights into controlling the optical properties and structure of SnO₂ nanoparticles.

Abstract

Purpose of the study: This study aims to compare the accuracy and reliability of Inductively Coupled Plasma Optical Emission Spectroscopy and Atomic Absorption Spectrometry in analyzing heavy metal contents specifically lead (Pb) and chromium (Cr) in textile wastewater. Methodology: The study employed a descriptive experimental method using water samples collected from a river suspected of contamination by textile waste. Tools used include AAS (APHA.322 B-2005), ICP OES (IK/LEL-ITS/ICP), and various laboratory glassware. Sample preparation followed SNI 6989.57:2008, and analytical validation included precision, accuracy, linearity, LOD, and LOQ testing. Main Findings: Both methods showed acceptable validation values, with linear regression coefficients (R²) above 0.995. ICP OES and AAS demonstrated good precision (%RSD ≤ 2%) and recovery rates between 93%–105%. However, significant differences were found between the two instruments (p = 0.012). Pb and Cr concentrations at discharge points exceeded regulatory limits. Novelty/Originality of this study: This study presents a comparative evaluation of ICP OES and AAS in the context of environmental monitoring, providing essential insights into their suitability for detecting heavy metals in complex wastewater matrices.

Abstract

Purpose of the study: This study investigates the effect of electrode quantity and voltage on MnO₂ nanoparticle yield and characteristics under acidic and basic conditions, while also evaluating MnO₂'s potential as an electrocatalyst in metal-air batteries. Methodology: Synthesis of MnO₂ was carried out by electrolysis of KMnO₄ solution with stirring using a magnetic stirrer. In acidic conditions, H₂SO₄ was used and the electrolysis process lasted for 30 minutes, while in basic conditions, 0.1 M KOH was used up to pH 9 and electrolysis for 24 hours. The research variables included voltage (2V and 4V) and the number of carbon electrodes (1 pair and 4 pairs). The electrolysis results were separated using a centrifuge, washed with demineralized water, and dried in a furnace. Main Findings: MnO₂ from electrolysis in acidic conditions tends to have a low crystalline structure, while in basic conditions it is amorphous with a larger surface area. The addition of electrodes and voltage reduces the surface area and increases particle agglomeration. Cyclic voltammetry tests show the ability of MnO₂ to reduce O₂ at all variables, in accordance with the standard oxygen reduction potential. Linear polarization tests show that MnO₂ synthesized in acidic conditions has better electrocatalytic activity than that synthesized in basic conditions. Novelty/Originality of this study: This study contributes data on the effect of electrolysis parameters on the yield and characteristics of MnO₂ as an electrocatalyst, and shows the best synthesis conditions for application in metal-air batteries.

Abstract

Purpose of the study: This study explores simple visible light spectroscopy to measure maximum absorption wavelengths in Fe(SCN)₃ and CuSO₄ solutions, analyzing the impact of light filters on absorption spectra. Methodology: This study exposed Fe(SCN)₃ and CuSO₄ solutions to tungsten lamp light, passing through a collimator and diffraction grating. Spectral data, recorded by a camera, compared filtered and unfiltered conditions. Absorbance, determined from light intensity differences, revealed characteristic wavelengths with maximum absorbance for each solution, visualized through wavelength-absorbance graphs. Main Findings: The maximum absorption wavelengths for Fe(SCN)₃ were 481 nm (with filter) and 472 nm (without filter), while for CuSO₄, they were 570 nm (with filter) and 553 nm (without filter). Monochromatic filters enhanced accuracy, aligning Fe(SCN)₃ closer to theoretical values and reducing CuSO₄ deviations to 20 nm (filtered) compared to 37 nm (unfiltered). Novelty/Originality of this study: The novelty of this study lies in the development of a simple visible light-based spectrophotometer by utilizing easily accessible tools and materials, such as tungsten lamps and CMOS cameras, to understand the maximum absorption peaks of Fe(SCN)₃ and CuSO₄ solutions. In addition, this study explores the effect of using light filters on the accuracy of spectrum data, providing a practical alternative for spectroscopy experiments in resource-limited learning environments.
