Abstract

The Gewang plant (Corypha utan Lamk) is an endemic plant that grows in the dominant vegetation of Timor Tengah Selatan (South Central Timor Regency). Nira is obtained from the gewang tree (Corypha utan Lamk) by inserting the what flower stems and then stored in a container for further fermentation with a mixture of red oak (Saccharum officinarum Linn), the hanging roots of the chickpeas (Ficus benjamina), the stems of the schleichera (Schleichera oleosa), the stem of the beetle (Ziziphus mauritiana L.), and the forest stems. (Piper aduncum L.). This study aims to study and describe the process of making sopi timor and analyze the scientific concepts that exist in the process. Based on the results of the study of the production of this sopi timor, public knowledge of fermentation and separation of solutions can be used as one of the materials to teach science content in the classroom with a local cultural approach. In the relationship between ESD and a Merdeka curriculum, there is a similar pattern of teachers taking a role in studying science in a contextual way that can be sourced from local cultures. It is intended for students to engage in meaningful learning processes because the context of their learning is related to their daily lives. The results of this research can be used as recommendations in context-based chemistry, biology, and physics learning in accordance with the culture in the South Central Timor Regency.

Abstract

Artificial Intelligence (AI) is advancing rapidly, and the increasing reliance on AI technology brings several advantages, such as improved efficiency, enhanced personalization, and smarter decision-making. However, this growing dependency also raises concerns regarding the epistemological foundations of AI. This study aims to examine the epistemology of AI development through qualitative research using a literature review approach. AI is a fusion of science and technology. Classical sources of knowledge, such as sensory experience, rationality, and testimony, remain crucial in human efforts to understand reality, despite AI offering sophisticated tools for data analysis and prediction. The knowledge produced by AI is complex and varies depending on the context and the type of system employed. AI’s complex algorithms, often perceived as a "black box," make it challenging to understand how AI arrives at specific conclusions, raising questions about the validity and reliability of its knowledge. Thus, understanding how AI functions, evaluating its sources, comparing them with other knowledge sources, and applying common sense are essential when analyzing AI-generated data.

Abstract

The process of learning science is inseparable from the nature of science, which includes knowledge about methods (epistemology), the process of science formation (ontology), and the values  and  beliefs  supporting  the  development of  science  (axiology). This  study  aims  to examine and explain Lavoisier’s law of conservation of mass (Lavoisier Law) through the lenses of epistemology, ontology, and axiology. The research employs a descriptive qualitative method, with document analysis involving the collection, analysis, and interpretation of non-numerical data from various articles published in both national and international journals. The results of this study reveal that the ontological analysis of Lavoisier’s law of conservation of mass can be observed through Lavoisier's experimental facts. The epistemological analysis of Lavoisier’s law explains how Antoine Lavoisier discovered the law and how its validity can be assessed. The axiological analysis of Lavoisier’s law is understood as a study of how the law is applied or utilized and its connection to moral and ethical considerations. The concept of Lavoisier’s law of conservation of mass can be taught using a real-world applications inquiry approach, involving activities such as conducting chemical reaction simulations, product design projects, and real- world case analyses. The real-world applications level can help students improve their skills in data collection and interpretation based on experiments, making predictions, and constructing logical arguments based on scientific evidence, as well as making and justifying decisions based on the obtained evidence

Abstract

Tradisi "mamat" atau konsumsi sirih pinang merupakan bagian penting dari kehidupan masyarakat di Kabupaten Timor Tengah Selatan (TTS), Nusa Tenggara Timur. Selain memperkuat ikatan sosial dan budaya, tradisi ini memiliki implikasi kesehatan melalui kandungan kimiawi sirih dan pinang. Penelitian ini bertujuan menganalisis tradisi "mamat" dari perspektif etnosains dan mengintegrasikannya dalam pembelajaran sains melalui pendekatan Education for Sustainable Development (ESD). Metode penelitian menggunakan pendekatan kualitatif deskriptif dengan studi literatur dengan mengumpulkan, menelaah, dan mensintesis informasi dari 26 artikel terkait etnosains, sirih pinang, dan aspek sosial dari aktivitas mengonsumsi sirih pinang. Hasil kajian menunjukkan bahwa sirih mengandung senyawa antiseptik, sedangkan pinang mengandung alkaloid stimulan. Namun, konsumsi jangka panjang berpotensi menyebabkan masalah kesehatan seperti kanker mulut. Studi ini juga mengusulkan integrasi tradisi "mamat" ke dalam pembelajaran sains untuk memberikan pemahaman mendalam kepada siswa mengenai perlunya keseimbangan antara pelestarian budaya dan pengelolaan risiko kesehatan. Simpulan dari penelitian ini menekankan pentingnya menggabungkan nilai-nilai budaya dengan pengetahuan ilmiah untuk mendorong kesadaran siswa tentang keberlanjutan sosial dan kesehatan.

Abstract

The Basic Chemistry Practicum I and II are integral components of the chemistry education curriculum, designed to develop students' Science Process Skills (SPS). However, the effectiveness of these programs is often constrained by misalignment between course objectives and practicum modules, insufficient laboratory facilities, and a lack of structured assessment tools. This study aims to evaluate the implementation of these practicum programs using the CIPP (Context, Input, Process, Product) evaluation model. A mixed-methods approach involved document analysis, questionnaires, and checklists. The evaluation was conducted within the Chemistry Education Study Program at a university in East Nusa Tenggara, Indonesia, with participants including 17 third-semester students, one lecturer, and one laboratory assistant. The findings reveal that while the practicum programs contribute to the achievement of learning outcomes, several issues remain. There are inconsistencies between the Semester Learning Plan (RPS) and practicum modules, particularly regarding the sequencing of materials and skill development targets. Students demonstrated moderate mastery of basic and integrated SPS but still required significant support in hypothesis formulation, data interpretation, and understanding of experimental variables. The study also found that instructional strategies and evaluation tools were not fully optimized to foster independent scientific inquiry. To enhance the program's effectiveness, the study recommends revising practicum modules to align more closely with course objectives, integrating interactive media such as virtual simulations, and developing formal assessment instruments to measure SPS development comprehensively. These improvements will better prepare students for complex laboratory work and strengthen their scientific reasoning as future educators.

Abstract

This study investigates the variations in the preparation of Semester Learning Plans (SLP) for the Basic Chemistry 1 course across 19 chemistry education programs at 31 universities in Indonesia. The study focuses on key aspects such as material coverage, learning methods, evaluation techniques, book references, and learning media used in each SLP. Using a qualitative descriptive approach and content analysis of 19 SLP documents, the study reveals significant diversity in the covered topics, teaching methods, and evaluation techniques employed across institutions. Core topics like stoichiometry and atomic structure are taught universally, but there is notable variation in specialized content such as green chemistry, air pollution, and tropical rainforests. The learning methods are primarily interactive, with group discussions and project-based learning being the most dominant. However, no program explicitly integrates the scientific method into its curriculum. Evaluation techniques vary, with most programs combining written exams and practical projects. This research concludes that the variations in SLP reflect institutional efforts to align curricula with local needs and global trends. It recommends expanding the sample scope in future studies and including qualitative data such as interviews with lecturers and student surveys for a more comprehensive understanding of how SLP impacts learning outcomes.
