Abstract

Guru sebagai orang yang berhadapan langsung dengan siswa dituntut untuk memiliki keterampilan literasi dasar dan numerasi dalam menciptakan kegiatan pembelajaran yang berkualitas. Faktanya masih banyak guru yang kurang mengembangkan kemampuan literasi dasar dan numerasinya dalam merancang kegiatan pembelajaran yang efektif dan produktif. Untuk membantu guru mengembangkan kemampuan literasi dasar dan numerasi, perlu dilakukan pendampingan melalui program pengabdian kepada masyarakat. Metode yang digunakan yaitu metode deskriptif melalui metode ceramah, diskusi interaktif dan pendampingan kepada guru mitra. Hasil kegiatan menunjukkan adanya peningkatan wawasan dan kemampuan literasi dasar dan numerasi guru dalam merancang dan mengembangkan kegiatan pembelajaran IPA yang efektif dan produktif. Hal ini ditunjukkan dari peningkatan kemampuan guru dalam mengembangkan perangkat pembelajaran berupa rencana pembelajaran, bahan ajar, LKPD, media dan instrumen tes berbasis literasi dasar dan numerasi. Peningkatkan kemampuan guru ini, juga diharapkan dapat meningkatkan kemampuan siswa dalam literasi yang pengukurannya melibatkan permasalahan berbasis keterampilan berpikir tingkat tinggi sebagaimana tertuang pada Asesmen Kompetensi Minimum (AKM) yang mengukur kemampuan bernalar tentang teks dan angka (literasi dan nurmerasi) yang meliputi keterampilan memilah serta mengolah informasi, berpikir logis-sistematis dan bernalar menggunakan pengetahuan.

Abstract

Tobacco smoking is known to have adverse health effects, including an increased risk of cancer , cardiovascular diseases, and respiratory disorders. These health risks are largely attributed to the presence of toxic compounds in tobacco smoke, such as polycyclic aromatic hydrocarbons (PAHs) and cyanide, both of which are carcinogenic. One potential method to mitigate these harmful effects is by using adsorbent materials, such as polyurethane foam, as smoke filters. This study aims to: (1) analyze the characteristics of polyurethane foam modified with aluminum metal, (2) evaluate the adsorption capability of the material against carcinogenic compounds in cigarette smoke using GC-MS analysis, and (3) determine the optimal adsorbent composition for maximum foam performance. Material characterization was conducted using FTIR to identify functional groups, swelling degree tests to assess water absorption capacity, SEM-EDX to examine surface morphology and aluminum distribution, and GC-MS to identify the carcinogenic compounds adsorbed. FTIR analysis revealed the presence of N-H, C-H, C=O, and C-C functional groups in the polyurethane structure. The swelling degree test showed a positive result, indicating good water absorption ability. SEM-EDX analysis demonstrated that aluminum particles were successfully distributed within the foam’s pores, resulting in smaller pore sizes. Furthermore, GC-MS results confirmed the adsorption of several carcinogenic compounds, including pyridine, eugenol, and benzenamine. These findings suggest that aluminum-modified polyurethane foam has the potential to serve as an effective filtering material to reduce exposure to toxic compounds in tobacco smoke.

Abstract

Experiential Learning (EL) is one of the 21st century learning models that provides students with more real and applicable learning experiences. Although EL has been widely used in various learning, there is still no comprehensive synthesis of how EL can be effectively implemented in various learning contexts to achieve various learning outcomes. This research aims to identify and synthesise the effectiveness of EL in improving and developing various learning outcomes. This research uses the Systematic Literature Review (SLR) method by analysing search results from the Scopus, Erics, Web of Science, and Google Scholar databases, in the last 10 years (2025-2015). Based on the search results, 16 suitable articles were obtained based on the inclusion and exclusion criteria. The results of the analysis of this article review can be drawn conclusions and findings that EL has a good impact on improving various learning outcomes, such as improving academic achievement, critical thinking skills, higher order thinking skills, collaboration, learning motivation, self-learning readiness, activeness, pedagogical skills, and problem-solving skills both at the elementary, junior high school, high school/vocational school and university levels. This research provides a comprehensive synthesis of the effectiveness of EL in improving and developing various learning outcomes.

Abstract

Thinking creatively is a crucial higher-order skill that students must acquire when they graduate from university. This necessitates lecturers designing and developing learning processes that actively engage students while fostering their creative thinking abilities. This study aims to develop and validate general chemistry teaching materials on organic compounds and reactions using the PjBL-STEM model and evaluate their effectiveness in improving students' creative thinking skills. The study employed the Analysis, Design, Development, Implementation, and Evaluation (ADDIE) model. The teaching materials were designed as comprehensive books that adhered to the PjBL-STEM framework. Effectiveness was measured by analyzing improvements in students’ creative thinking abilities through quantitative testing. The results demonstrate that the PjBL-STEM-based teaching materials are valid and feasible for implementation. Their effectiveness in enhancing students' creative thinking abilities was statistically significant (t-count = 32.488; p = 0.000), with an average improvement of 42.725 ± 8.317. The development of PjBL-STEM-based teaching materials offers a valuable tool for chemistry education, effectively promoting creative thinking skills among students. This approach provides a practical framework for lecturers to design innovative, student-centered learning strategies.
