Purpose of the study: This study aims to determine the effect of Kahoot game media on students' interest and learning outcomes in chemistry lessons.

Methodology: The method used is an experimental method with a quantitative approach to determine the level of interest and learning outcomes of students and to compare the level of interest and learning outcomes of students in the control class and the experimental class.

Main Findings: The results of the t-test show a significance value of 0.000, then Sig. ˂ 0.05 so that there is an influence between the Kahoot game media and students' interest in learning. These results are supported by observation data with a significance value of 0.015, then Sig. ˂ 0.05. So it can be concluded that there is an influence between the Kahoot game media and students' interest in learning. The results of the Mann-Whitney test show a significance value of 0.749, then Sig. ˃ 0.05 so that it can be concluded that there is no significant influence between the use of Kahoot game media and students' learning outcomes.

Novelty/Originality of this study: The novelty of this study lies in the use of Kahoot game media as an interactive approach to improve students' interest and learning outcomes in abstract and complex Chemistry lessons. This study is also relevant in the context of post-pandemic digital learning that demands technology-based innovation.

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.

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.

From Risk to Safety: Applying Job Safety Analysis in Organic Chemistry Practicals for Future Chemistry Educators

Dwi Ahmad Nur Ramadhani, Basil Marasinghe, Marilyn B. Castillo — Sat, 21 Jun 2025 00:00:00 +0700

Purpose of the study: This study aims to determine the use of Job Safety Analysis in analyzing potential hazards in Organic Chemistry practicums as an effort to implement occupational safety and security for chemistry education students.

Methodology: The method used is descriptive qualitative. The sample of this study was 41 students of the Chemistry Education Study Program. The instruments used were the Job Safety Analysis observation sheet and semi-structured interviews. The stages in analyzing potential hazards using the Job Safety Analysis method are (1) choosing a job, (2) determining the work steps, (3) identifying and analyzing potential hazards in each step of the work and (4) making efforts to control potential hazards.

Main Findings: The results of the study showed 16 potential hazards identified using the Job Safety Analysis method. The results of the analysis of the risk level value (Risk Level) of potential hazards in all work steps divided into four stages of the practicum showed that 19% were (Extreme Risk-Very High Risk), 27% were (High Risk-High Risk), 19% were (Moderate Risk-Moderate Risk) and 35% were (Low Risk-Low Risk).

Novelty/Originality of this study: This study provides an innovative contribution to the development of occupational safety culture in educational environments by integrating JSA as a preventive measure based on practical risk analysis.

Which Is More Reliable? ICP-OES vs AAS for Chromium and Lead Analysis in Heavy Metal Monitoring

Seerwan Fadhil Shawkat, Shimaa A Ahmed, Sumaira Nadeem — Sat, 21 Jun 2025 00:00:00 +0700

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.
