Abstract

Science process skills (SPS) are one of the skills needed in the chemistry learning process, in order to gain a complete understanding of the concepts. This skills categorized into two types; basic and integrated. This research aimed to develop a product of Augmented Reality (AR) learning media then to know its feasibility, practicality, and effectiveness on students’ basic SPS on acid base learning. The research adopted Research and Development (R&D) with 4-D model consisted of define, design, develop, and disseminate stages. Questionnaire was used to measure the feasibility and practicality. Then, the obtained data were analyzed by qualitative and quantitative descriptive. In addition, SPS test was used to measure the effectiveness of AR learning media and the data were analyzed by the test of One-way ANOVA, Tukey’s Post Hoc test, and General Linear Model (GLM) Univariate. The result showed that the AR learning media is feasible, practical, and effective with big influence to support students’ basic SPS on acid base learning.

Abstract

Penggunaan laboratorium fisika dasar memiliki peran penting dalam meningkatkan kompetensi mahasiswa Pendidikan Fisika Universitas Negeri Manado. Namun, keterbatasan panduan eksperimen yang sistematis dan mudah diakses seringkali menjadi kendala dalam pelaksanaan praktikum yang efektif. Penelitian ini bertujuan mengembangkan e-book panduan eksperimen berbasis FlipHTML5 sebagai sarana pembelajaran interaktif bagi mahasiswa. Metode yang digunakan adalah model pengembangan 4D (Define, Design, Develop, Disseminate). Validasi produk dilaksanakan oleh 7 reviewer menggunakan instrumen kuisioner aspek materi, bahasa, dan media, sedangkan kepraktisan diujikan kepada 20 mahasiswa. Hasil analisis menunjukkan e-book ini sangat layak dengan skor rerata tiap aspek di atas 4,20 dan sangat praktis dengan skor rerata 4,40. PEKA RASA memudahkan mahasiswa mengakses, memahami dan memberikan instruksi eksperimen yang jelas. Dengan demikian e-book ini berimplikasi pada kualitas pembelajaran laboratorium yang lebih adaptif terhadap kebutuhan digital, berpotensi menjadi media pembelajaran interaktif yang mendukung efektivitas laboratorium dan dapat dikembangkan lebih lanjut untuk alat laboratorium lainnya. Development of an e-book guide to basic physics laboratory experiments as an interactive learning tool Abstract: Using a basic physics laboratory has a vital role in improving the competence of Physics Education students at Manado State University. However, the limitations of a systematic and easily accessible experimental guide are often an obstacle to effective practicum implementation. This research aims to develop a FlipHTML5-based experiment guide e-book as an interactive learning tool for students. The method used is the 4D development model (Define, Design, Develop, Disseminate). Product validation was carried out by 7 reviewers using questionnaire instruments on material, language, and media aspects, while practicality was tested on 20 students. The analysis results show that this e-book is very feasible, with an average score of each aspect above 4.20, and very practical, with an average score of 4.40. PEKA RASA makes it easy for students to access, understand, and provide clear experimental instructions. Thus, this e-book has implications for the quality of laboratory learning that is more adaptive to digital needs, has the potential to become an interactive learning media that supports laboratory effectiveness, and can be further developed for other laboratory equipment.

Abstract

This quantitative research focuses on defining the profile of students’ Higher Order Thinking Skills (HOTS) using Two-Tier Multiple Choice Test (TTMCT) instrument. The research carried out in SMAN 2 Toraja Utara, Indonesia. From the entire 11th grade science, 109 students were chosen as participant by purposive sampling. TTMCT consisting of 15 questions about acid base concepts with the cognitive domains of analyzing (C4 and evaluating (C5) was used. Before its implementation, the test underwent a rigorous validation and reliability process. The validation provided confidence in the instrument's ability to effectively measure the intended variables and The Cronbach's alpha coefficient of this instrument is 0.71. This study presents two comprehensive results: firstly, students’ HOTS profile is dominated in good category with an average score of 63.83, and secondly, the comparison of cognitive level: analyzing (C4) with the mean percentage is 71.32% then evaluating (C5) cognitive level with the mean percentage is 60.80%.

Abstract

SPSS (Statistical Product and Service Solution) is a statistical analysis software widely used in quantitative research. A socialization program on SPSS usage for students of the Faculty of Mathematics, Natural and Earth Sciences (FMIPAK) at Manado State University (UNIMA) aimed to enhance their understanding and skills in data processing, result interpretation, and overcoming challenges such as limited statistical uses and software access. The activity was conducted through three main stages: introduction to the SPSS interface, technical training (descriptive analysis, parametric and non-parametric tests), and consultation sessions to address specific student inquiries. Active participation indicated high enthusiasm, with evaluation results showing an improved ability to operate SPSS and interpret analytical outputs independently. Technical issues, such as internet connectivity during software downloads, provided lessons for future event preparations. This program not only supports academic tasks (e.g., thesis completion) but also equips students with analytical competencies relevant to professional settings. Training programs are necessary to strengthen mastery of modern statistical tools, ensuring students are prepared for research challenges and competitive job market demands.

Abstract

Atap Tongkonan Tanete, rumah adat masyarakat Toraja di Sulawesi Selatan, merupakan warisan budaya yang kaya akan nilai filosofis dan estetika. Penelitian ini bertujuan untuk menganalisis struktur atap Tongkonan dari perspektif sains, khususnya melalui konsep kesetimbangan benda tegar dan integral. Untuk menganalisis prinsip-prinsip fisika dan matematika yang mendasari desainnya. Penelitian ini menggunakan pendekatan kualitatif – deskriptif yang menggabungkan observasi lapangan, wawancara dengan pemangku kepentingan lokal, dan studi literatur tentang arsitektur Tongkonan dan prinsip-prinsip fisika. Data dianalisis menggunakan perangkat lunak GeoGebra untuk memodelkan bentuk atap sebagai fungsi kuadrat dan menghitung luas area bawah serta panjang kurva dengan menggunakan integral. Hasil menunjukkan bahwa bentuk lengkung atap Tongkonan memastikan distribusi beban yang merata. Analisis ini membuktikan bahwa kearifan lokal masyarakat Toraja dalam membangun Tongkonan mengintegrasikan prinsip-prinsip fisika dan matematika.

Abstract

Metacognitive awareness is essential in fostering students' ability to regulate their own learning processes, especially in complex subjects like analytical chemistry. This study investigates the effectiveness of a Problem Based Learning (PBL) model assisted by Blended Learning in enhancing metacognitive awareness among university students in the topic of UV-Vis spectroscopy. Using a quasi-experimental design, two groups were compared: an experimental group receiving PBL combined with Blended Learning, and a control group receiving conventional PBL. Data collection involved pretest and posttest cognitive assessments, metacognitive awareness questionnaires, and observation of student engagement on the Edmodo platform. The results demonstrate significant improvement in the experimental group’s posttest cognitive scores (mean = 85.59) compared to the control group (mean = 77.37), with effects also observed in metacognitive awareness and self-regulation skills (p < 0.05). These findings suggest that integrating Blended Learning into the PBL framework can effectively enhance cognition, metacognitive skills, and student motivation in chemistry education. The study encourages the adoption of this blended instructional strategy and further research on its wider applicability.
