Abstract

PISA and TIMSS results have been used as a basis for educational reform, but unfortunately, teachers’ understanding of PISA and TIMSS tests is rarely investigated. We evaluated 149 sophomore preservice chemistry teachers’ achievement in TIMSS and PISA-like test. As a way to reflect on TIMSS and PISA results, we compared preservice chemistry teachers’ achievement to PISA and TIMSS results for Indonesia and the international students. Results suggested that, to a certain degree, preservice chemistry teachers have a better chemical literacy than Indonesian students and a somewhat similar chemical literacy with international students.

Abstract

This research is intended to synthesize Sn-ZIF-8 with an environmentally friendly hydrothermal method by exploring the potential of the utilization of aqueous solvents as the main solvent. Sn-ZIF-8 material has been successfully synthesized with water solvent at room temperature and has been characterized using XRD, FTIR, and SEM instrumentation to determine the extent of synthesis success. In this study, the use of Sn doping varied from 5, 10, and 15%, while MeIM, NH4OH, and water precursors were kept constant. Instrumentation observations showed the XRD patterns of Sn-ZIF-8 compounds for percentages of 5, 10, and 15% of Sn2+ displayed specific peaks of ZIF-8 at 2 = 7.24, 10.28, 12.62, 16.34, and 17.92. Meanwhile, the FTIR spectra of all synthesized solids presented the same functional group absorption peaks as the simulated ZIF-8 solids. SEM observation revealed a regular crystal shape of Sn-ZIF-8 without any contaminant on its surface. The characterization results show no change in the basic structure and the addition of other structures from ZIF-8. The implication of this finding can be utilized as a reference source for synthesizing inorganic materials using eco-friendly stages without affecting the synthesized product

Abstract

Air Masin Village is a rice farming center currently facing serious challenges in sustainable production. Over the past five years, rice productivity has declined by 15%, allegedly due to the excessive use of synthetic fertilizers and pesticides. This practice has led to soil fertility degradation and increased pest resistance to chemical pesticides. In response to these issues, this community service program was designed to introduce locally sourced plant-based biostimulants as an environmentally friendly agricultural solution. Biostimulants have the potential to improve soil health, stimulate plant growth, and increase resilience to biotic and abiotic stress. This community service program aims to provide training to farmers in Air Masin Village on the techniques for producing and applying locally sourced plant-based biostimulants, thereby reducing dependence on synthetic chemical inputs. Furthermore, this program also aims to increase farmers' capacity in managing sustainable agricultural systems and open new business opportunities in the production and marketing of biostimulants. Several methods and stages of implementation were implemented, including identifying partner problems, activity outreach, training in the production of plant-based biostimulants, biostimulant effectiveness testing, farm management training, operational assistance, and finally, monitoring and evaluation. The training that has been implemented has had a positive impact on the local community, namely by changing mindsets and behavior regarding the importance of environmentally friendly agriculture.

Abstract

The Merdeka Curriculum requires interactive digital media, but chemistry learning, especially on chemical bonding material, is still dominated by limited and uninteresting media. Previous studies have produced useful teaching materials, but they are generally small in scale, not yet integrated with PBL, or have not maximized the features of digital flipbooks, so there is still a need for more innovative media. This study developed a flipbook medium based on Problem-Based Learning (PBL) to enhance the effectiveness of chemical bonding instruction. The purpose of this research was to determine the needs, feasibility, practicality, and attractiveness of the developed flipbook. This research employed a Research and Development (R&D) design using the ADDIE model, which includes the stages of analysis, design, development, implementation, and evaluation. The instruments used consisted of interview questionnaires, needs analysis questionnaires, expert validation questionnaires (media and material), as well as practicality and attractiveness questionnaires. The research subjects were chemistry teachers and high school students at public senior high schools in Langsa City. The results of the teacher needs assessment showed a percentage of 71.1%, categorized as “needed.” Media and material expert validations yielded average scores of 0.87 and 0.83, respectively, both classified as “highly feasible.” The media trials with teachers and students resulted in practicality and attractiveness scores of 95% and 83.09%, respectively, categorized as “highly practical” and “highly attractive.” It can be concluded that the PBL-based flipbook developed in this study is practical, useful, and engaging in supporting more effective learning processes. Therefore, this medium can support the implementation of the Merdeka Curriculum through interactive digital learning. Keywords: flipbook; problem-based learning; chemical bonding. Abstrak. Kurikulum Merdeka menuntut media digital yang interaktif, tetapi pembelajaran kimia, terutama pada materi ikatan kimia masih didominasi media yang terbatas dan kurang menarik. Penelitian sebelumnya menghasilkan bahan ajar yang bermanfaat, namun umumnya berskala kecil, belum terintegrasi PBL, atau belum memaksimalkan fitur flipbook digital, sehingga masih terdapat kebutuhan akan media yang lebih inovatif. Penelitian ini mengembangkan media flipbook berbasis Problem Based Learning (PBL) untuk meningkatkan efektivitas pembelajaran ikatan kimia. Tujuan dari penelitian ini adalah untuk mengetahui kebutuhan, kelayakan, kepraktisan dan kemenarikan media flipbook yang dikembangkan. Jenis penelitian ini merupakan penelitian pengembangan (R&D) yang menggunakan model ADDIE yang meliputi tahap analisis, perancangan, pengembangan, implementasi, dan evaluasi. Instrumen yang digunakan meliputi angket wawancara, angket analisis kebutuhan, angket validasi ahli (media dan materi) serta angket kepraktisan dan kemenarikan. Subjek penelitian ini adalah guru kimia dan siswa SMA Negeri di Kota Langsa. Hasil penilaian kebutuhan guru menunjukkan persentase 71,1% yang diklasifikasikan sebagai “dibutuhkan”. Validasi oleh ahli media dan ahli materi menghasilkan skor rata-rata 0,87 dan 0,83 yang termasuk dalam kategori “sangat layak”. Uji coba media dengan guru dan siswa menghasilkan kepraktisan sebesar 95% dan kemenarikan sebesar 83,09%, yang keduanya termasuk dalam kategori “sangat praktis” dan “sangat menarik”. Dapat disimpulkan bahwa flipbook berbasis PBL yang dikembangkan dinilai praktis, bermanfaat dan menarik untuk mendukung proses pembelajaran yang lebih efektif. Sehingga media ini dapat mendukung implementasi Kurikulum Merdeka berbasis pembelajaran digital interaktif.
