Abstract

This study aims to evaluate the usefulness and efficiency of the Ludo Kimia game as a teaching aid on acid and base materials in relation to the learning outcomes of SMA Nurfalah class XI students. This study used a Pretest-Posttest Control Group Design, with XI MIPA 1 class as the control group and XI MIPA 2 as the experimental group at Nurfalah School. Data collection used a practicality questionnaire and pretest-posttest assessment. Practicality was analyzed using the percentage score, while effectiveness was assessed using the N-Gain method. The results showed that teachers rated the Ludo Kimia game as very practical, while students rated it as quite practical. In terms of effectiveness, this game is considered quite effective in improving student learninfgg outcomes. The experimental class showed a greater increase in conceptual understanding than the control class, with an average posttest score of 77.14 and 70.15 respectively. The N-Gain value for the experimental class was 0.59 (medium category), while the control class obtained a value of 0.51 (low category). Furthermore, the hypothesis test showed a significant difference between the two groups, with t_hitung (3.62) > t_table (1.67) at the 0.05 significance level. In conclusion, the Ludo Kimia game is a very practical media for teachers, quite practical for students, and quite effective in improving student learning outcomes on the topic of acid-base. This game can be an alternative media in learning chemistry to increase engagement and academic achievement.

Abstract

This research explores the chemical constituents of bottled drinking water, emphasizing the presence of inorganic and organic pollutants, microplastics, and disinfection byproducts. Samples from five top-selling PET-bottled water brands were analyzed in triplicate under different storage temperatures (room temperature, 4°C, and 40°C). Various analytical techniques were employed: Atomic Absorption Spectroscopy (AAS) to quantify heavy metals (Pb, Cd, Sb), Gas Chromatography–Mass Spectrometry (GC-MS) to detect bisphenol A (BPA) and phthalates, Fourier Transform Infrared Spectroscopy (FTIR) for microplastic identification, and High-Performance Liquid Chromatography (HPLC) to assess trihalomethanes (THMs). Antimony (Sb) was consistently detected, with concentrations increasing markedly at elevated temperatures. BPA appeared in 60% of samples and showed a temperature-dependent increase and inverse correlation with pH. All samples contained microplastics (mean 22 ± 8 particles/L), primarily PET, polypropylene (PP), and polyethylene (PE). Although all contaminant levels were within regulatory thresholds, repeated intake under suboptimal storage conditions may raise cumulative exposure. The results emphasize the need for stricter regulatory measures, enhanced labeling for storage, and standardized guidelines concerning microplastics. This study enhances current understanding by demonstrating how storage conditions influence chemical leaching and potential health risks linked to long-term bottled water consumption.
