Abstract

Structural modification of the sensor is necessary to improve the sensitivity of cyanide ion (CN⁻) detection, which has a threshold of 1.9 × 10⁻⁶ M according to WHO. This study aims to evaluate the potential of (E)-2-(benzoxazol-2-yl)-3-phenylacrylonitrile (S6) as a benzoxazole-based cyanide ion sensor through a computational approach. This study used DFT/B3LYP/6-31G(d) and TD-DFT methods to analyze electronic properties, molecular interactions, absorption shifts, binding constants, detection limits, and electrostatic potential maps. The results show that the addition of a dicyanovinyl group to S6 produced a HOMO energy of -5.9247 eV, a LUMO energy of -3.2493 eV, and an energy gap (ΔE) of 2.6754 eV. The interaction of S6 with CN⁻ formed the S6-CN complex through nucleophilic addition and N-H···N≡C hydrogen bonding, which narrowed ΔE to 2.3829 eV and induced a bathochromic shift of 69 nm from 352 nm to 421 nm. The binding constant k_bind value of 1.25 × 10⁴ M⁻¹ and detection limit of 1.4 × 10⁻⁵ M indicate that S6 has 31-fold higher sensitivity than S5. The ESP map confirms that N-H, with a value of +45.2 kcal/mol, acts as the active site. The conclusion of this study affirms that the dual mechanism in S6 supports high selectivity toward CN⁻ and contributes to the rational design of benzoxazole-based cyanide sensors.

Abstract

Rapid detection of cyanide ions (CN⁻) with a WHO threshold of 1.9 × 10⁻⁶ M requires the development of an economical and selective colorimetric sensor. This study aims to evaluate 1-phenyl-1H-benzimidazole (S5) as a candidate CN⁻ sensor through a computational approach. This study used DFT/B3LYP/6-31G(d) and TD-DFT methods to analyze electronic properties, molecular interactions, UV-Vis spectral shifts, binding constants, detection limits, and electrostatic potential maps. The calculation results show that S5 has a HOMO energy of -5.5325 eV, a LUMO energy of -2.5569 eV, and an energy gap (ΔE) of 2.9757 eV. The interaction of S5 with CN⁻ formed the S5-CN complex through N-H···N≡C hydrogen bonding, which narrowed ΔE to 2.6578 eV or decreased it by 0.3179 eV. This narrowing of ΔE induced a bathochromic shift in the UV-Vis spectrum, which serves as the basis for color change. The binding constant k_bind value of 2.9 × 10³ M⁻¹ and detection limit of 4.36 × 10⁻⁴ M indicate that S5 has moderate affinity, but its sensitivity remains low. The ESP map confirms that N-H acts as the active site. The conclusion of this study affirms that although S5 is selective toward CN⁻, its detection limit remains 230 times above the WHO threshold, indicating that further structural modification is required. This study provides an initial contribution to establishing S5 as a basic framework for the design of next-generation benzimidazole-based cyanide sensors.

Abstract

This study was motivated by the need to develop innovative, visual, and concise learning media to support students’ understanding of the aldol reaction topic in the Mechanisms and Synthesis of Organic Compounds (MSSO) course. This study aims to analyze the need for developing a chemistry magazine on the topic of aldol reactions, particularly crossed aldol reactions. This descriptive study with a mixed-method approach involved 31 Chemistry Education students at the University of Mataram from the 2022 cohort who had taken the MSSO course. The research instruments included a needs analysis questionnaire consisting of nine questions, semi-structured interview guidelines for three informants, and a document analysis sheet. Quantitative data were analyzed using descriptive percentages, whereas qualitative data were analyzed through the stages of data reduction, data presentation, and conclusion drawing. The results showed that all students (100%) experienced difficulties in understanding the mechanism of crossed aldol reactions, while the available learning media, namely PowerPoint presentations and textbooks, were considered ineffective by 100% of respondents. In addition, 93.5% of students strongly agreed that a chemistry magazine was the desired learning medium. Students’ preferences for reading supplements included colorful layouts (87.1%), a combination of text and images (90.3%), and a communicative language style (83.9%). These findings indicate a gap between students’ need for innovative, visual, and concise reading supplements and the reality of learning, which still relies on conventional media. The conclusion of this study affirms that the results of the needs analysis serve as an important basis for developing a chemistry magazine on crossed aldol reaction material as a valid, practical, and effective reading supplement.

Abstract

Although students’ critical thinking skills have received wide attention in educational research, studies that specifically examine the implementation of the POE2WE learning model at the senior high school level remain relatively limited. This study aimed to analyze the effect of the POE2WE learning model on the critical thinking skills of Grade XI students at SMAN 8 Mataram in the 2025/2026 academic year. A quantitative approach with a quasi-experimental method was employed, using a pretest–posttest control group design involving 64 students selected through purposive sampling. Data were collected using an essay test consisting of five items that had been tested for validity and reliability, then analyzed through normality and homogeneity tests, followed by hypothesis testing using a t-test at a 0.05 significance level. The results showed a statistically significant difference in critical thinking skills between students taught using the POE2WE learning model and those receiving conventional instruction, with a significance value of 0.004 (< 0.05). These findings contribute to the development of constructivist learning theory and provide empirical support for the effectiveness of the POE2WE model in enhancing students’ critical thinking skills in the senior high school context. The study concludes that the POE2WE learning model plays an important role in developing critical thinking skills and deserves consideration as an alternative instructional approach in classroom practice.

Abstract

Penelitian ini bertujuan untuk analisis awal sikap peduli lingkungan dan pemahaman ilmiah siswa SMA pada mata pelajaran Kimia sebagai landasan awal pengembangan perangkat pembelajaran berbasis etnosains-STEM. Metode yang digunakan adalah survei deskriptif dengan subjek 120 siswa kelas X, XI, dan XII yang mengikuti pembelajaran Kimia dari tiga wilayah berbeda: Kota Mataram (n=92), Lombok Barat (n=19), dan Lombok Utara (n=9). Instrumen berupa angket tertutup dengan empat indikator: sikap peduli lingkungan (W), pemahaman dampak aktivitas manusia terhadap ekosistem air (X), kesediaan terlibat dalam konservasi (Y), serta pengaruh pembelajaran Kimia terhadap kesadaran isu energi dan keberlanjutan (Z). Data dianalisis secara deskriptif persentatif dan uji chi-square (α=0,05). Hasil penelitian menunjukkan bahwa secara keseluruhan sikap peduli lingkungan siswa tergolong tinggi (72,5%), kesediaan terlibat dalam konservasi juga tinggi (74,2%), dan pembelajaran Kimia telah meningkatkan kesadaran isu energi dan keberlanjutan pada 74,6% siswa. Namun, pemahaman siswa tentang dampak aktivitas manusia terhadap ekosistem air hanya mencapai 49,7% (kategori sedang), sehingga terdapat kesenjangan sebesar 22,8 poin persentase antara sikap dan pemahaman. Berdasarkan wilayah, kesenjangan terbesar terdapat di Kota Mataram (-26,1 poin), disusul Lombok Utara (-22,3 poin), dan terkecil di Lombok Barat (-10,6 poin). Hasil uji chi-square menunjukkan bahwa secara statistik tidak terdapat perbedaan signifikan antar ketiga wilayah pada semua indikator (p-value > 0,05), artinya karakteristik siswa relatif sama meskipun secara deskriptif terdapat variasi. Sehingga,. perangkat pembelajaran dapat dirancang dengan memperhatikan konteks lokal masing-masing wilayah meskipun secara statistik tidak terdapat perbedaan signifikan.

Abstract

Implementation of Integrated Problem-Based Learning and Storytelling Technique on Learning Outcomes and Attitudes Towards Chemistry. Objective: This study aims to analyze the effect of problem-based learning (PBL) integrated with storytelling on learning outcomes and attitudes towards chemistry in basic chemistry courses. Methods: This experimental study employed a pretest-post-test control group design. The sample consisted of 99 new students from the Faculty of Agricultural Technology enrolled in basic chemistry courses, with 49 students in the experimental group and 50 in the control group. The research instruments included a critical thinking test with 15 validated multiple-choice questions (Cronbach's alpha = 0.817) and an attitude towards chemistry instrument based on four categories (Cronbach's alpha = 0.765). Data analysis was performed using MANOVA. Results: The results showed that the N-gain of student learning outcomes was higher in the experimental group compared to the control group. Similarly, students' attitudes towards chemistry in the experimental group, which received PBL with storytelling integration, were higher in all categories than those in the control group. The highest attitude scores in the experimental group were in the categories of attitude towards chemistry material and confidence in learning chemistry, while the lowest score was in the category of attitude towards chemistry laboratory work. In the control group, the highest score was in the category of the tendency to learn chemistry, with the lowest score matching the experimental group's lowest category. The MANOVA test indicated a significant effect of PBL with storytelling integration on both learning outcomes and attitudes towards chemistry. Conclusion: Implementing problem-based learning integrated with storytelling in basic chemistry courses positively influences learning outcomes and attitudes towards chemistry, with the experimental group showing better results compared to the control group. Keywords: attitudes towards chemistry, critical thinking, storytelling, problem based learning.DOI: http://dx.doi.org/10.23960/jpp.v14.i2.202477
