Abstract

This research aims to identify the potential of medicinal plants in Pampang Village, Samarinda, East Kalimantan, which can be used as a source of chemistry learning at the junior and senior high school levels. This research used a descriptive method with a qualitative approach. Data collection was carried out through observation, interviews, and documentation. The research subjects, namely 11 residents of Pampang Village, were determined using purposive sampling. Data analysis used interactive model analysis, and data validity is measured using data triangulation techniques. The results of the research show that there are 20 medicinal plants that the people of Pampang Village widely used and eight medicinal plants have the potential to be used as a source of chemistry learning. These medicinal plants were sambung nyawa, meniran, bajakah, betel, seri, turmeric, coconut, and tamarind eggplant. These plants related to materials separating mixtures, reaction rates, functional groups, lipids, acid and base indicators, electrolyte and non-electrolyte solutions, acids and bases, chemical changes, and redox. Therefore, this can be used as a reference and consideration for chemistry teachers in the learning process. to help students understand chemistry lessons closely related to everyday life.

Abstract

Berpikir kritis ialah salah satu kemampuan yang wajib dimiliki siswa dalam menghadapi tantangan abad ke-21. Kemampuan ini membantu siswa untuk berpikir secara logis, serta mampu mengevaluasi berbagai informasi yang mereka terima, khususnya di era digital. Tujuan penelitian ini adalah untuk menemukan perbedaan antara model Process Oriented Guided Inquiry Learning (POGIL) dan model Discovery Learning pada kemampuan berpikir kritis siswa pada materi aditif dengan metode penelitian kuantitatif. Populasi penelitian yakni semua siswa kelas VIII SMP Negeri 2 Samarinda yang terdiri dari sebelas kelas. Penentuan dilaksanakan dengan teknik cluster random sampling yang tersusun dari dua kelas yakni kelas eksperimen 1 memakai model Discovery learning (DL) dan kelas eksperimen 2 memakai model Process Oriented Guided Inquiry Learning (POGIL). Desain penelitian ini memakai post-test only group design. Instrumen yang digunakan pada penelitian ini adalah instrument tes berupa soal uraian (essay) dengan menggunakan 6 indikator berdasarkan Fisher meliputi mengidentifikasi masalah, menyusun alternatif pemecahan masalah, mengumpulkan infomasi relevan, mengungkapkan pendapat, membuat kesimpulan, mengevaluasi argumen. Data dianalisis dengan memakai uji Independent Sample T-test. Hasil analisis menunjukkan jika siswa pada kelas yang menerapkan Process Oriented Guided Inquiry Learning (POGIL) (69,27) mempunyai rata-rata kemampuan berpikir kritis yang lebih tinggi dibandingkan dengan siswa pada kelas Discovery Learning (59,90). Aktivitas guru dan siswa menunjukkan bahwa tingkat keterlibatan dalam pembelajaran Discovery learning mencapai 93% dan tingkat keterlibatan dalam pembelajaran Process Oriented Guided Inquiry Learning (POGIL) mencapai 97%. Dengan demikian, terdapat perbedaan kemampuan berpikir kritis antara model Process Oriented Guided Inquiry Learning (POGIL) dengan model Discovery Learning (DL).

Abstract

Kompetensi pedagogik merupakan salah satu keterampilan utama yang harus dimiliki oleh calon guru kimia untuk menciptakan pembelajaran yang efektif dan bermakna. Penelitian ini bertujuan untuk meningkatkan kompetensi pedagogik calon guru kimia melalui pembelajaran mikro reflektif. Metode yang digunakan adalah Penelitian Tindakan Kelas (PTK) yang dilaksanakan dalam tiga siklus. Setiap siklus terdiri atas tahapan perencanaan, pelaksanaan, observasi, dan refleksi. Subjek penelitian adalah mahasiswa semester 6 Program Studi Pendidikan Kimia Universitas Mulawarman. Data dikumpulkan melalui lembar observasi, jurnal reflektif, angket, dan dokumentasi. Hasil penelitian menunjukkan bahwa pembelajaran mikro reflektif mampu meningkatkan kompetensi pedagogik calon guru kimia secara bertahap. Pada siklus pertama, peserta mulai mengenali kelemahan dalam perencanaan dan pelaksanaan pembelajaran. Melalui refleksi, perbaikan dilakukan pada siklus kedua dan ketiga, yang berfokus pada penggunaan metode pembelajaran, manajemen kelas, dan evaluasi pembelajaran. Peningkatan signifikan terlihat pada keterampilan mahasiswa calon guru kimia dalam dua aspek, yaitu keterampilan mengajar dan keterampilan membuat perangkat ajar, setelah melakukan praktik mengajar melalui tiga siklus. Penelitian ini menyimpulkan bahwa pembelajaran mikro reflektif merupakan pendekatan yang efektif untuk mengembangkan kompetensi pedagogik mahasiswa calon guru kimia.

Abstract

Concepts in chemistry, such as colloids, remain challenging for students who struggle to grasp them, and current instructional media used by teachers have not optimally visualized these concepts. This study aims to analyze students’ needs for Articulate Storyline 3–based interactive learning media, supported by Canva, for the colloid topic. Employing a descriptive quantitative design, the study sampled one chemistry teacher and 40 twelfth-grade students from SMA IT Granada Samarinda selected through purposive sampling. Data were collected via questionnaires and an unstructured interview with the teacher. The questionnaire’s validity and reliability were evaluated using Pearson’s Product-Moment correlation in IBM SPSS 27, and questionnaire data were analyzed using descriptive percentage statistics. Findings indicate that 84.5% of students have adequate access to digital devices, 83% prefer visually oriented learning media, and 76.5% express a need for interactive learning tools. The proposed interactive media, developed with Articulate Storyline 3 and Canva, are expected to include instructional videos, interactive exercises, and simple educational games aligned with colloid concepts, making learning more engaging and accessible. This study can serve as a foundation for further development of innovative, adaptive interactive learning media.

Abstract

Understanding chemical reaction rates requires practical experiences that allow students to observe factors influencing reaction speed. However, limited laboratory equipment and materials in many schools hinder the implementation of meaningful experiments. This study aims to determine the learning media needs of Class XI students for the development of reaction rate experimental videos at SMA Negeri 7 Malinau. A total of 17 students (n = 17) and one science teacher participated in the study. Data were collected using questionnaires and interviews, then analyzed through descriptive, qualitative, and quantitative approaches. The results show that 88.24% of students experience difficulties in learning reaction rate concepts, 76.47% perceive that videos help their understanding, and 100% agree that experimental videos are needed as learning resources. These findings highlight the urgent need for offline, visually engaging, and easy-to-understand experimental videos to support students’ conceptual understanding in contexts with limited laboratory facilities. The results of this needs analysis will directly inform the content design, structure, and visual features of the reaction rate experimental videos to be developed.

Abstract

This study aims to analyze students' needs as a basis for developing ethnoscience-based chemistry teaching materials on chemical equilibrium by integrating the context of the mangrove ecosystem in Paser Regency, East Kalimantan. The study used a quantitative descriptive approach with a survey design of 40 grade XI students at SMA Negeri 1 Tanah Grogot through a Likert scale questionnaire compiled based on 13 indicators and grouped into four dimensions, namely the relevance of teaching materials, conceptual understanding, learning experience and technology involvement, and the integration of ethnoscience and local wisdom. The research findings indicate that the teaching materials used are still abstract and have not optimally accommodated the local context, while students show a high need for additional teaching materials and learning related to the mangrove ecosystem.. This study contributes to the development of ethnoscience-based chemistry education by demonstrating the potential of mangrove ecosystems as a local context for learning chemical equilibrium. The empirical evidence obtained provides a foundation for the development of ethnoscience-based teaching materials that can connect abstract chemical concepts with local environmental phenomena close to students' lives.
