Abstract

The application of probing and prompting techniques is the application of science and technology by conducting investigations or examinations by relating questions in the form of cause and effect aimed at encouraging or guiding the achievement of satisfactory learning outcomes. The application of probing and prompting techniques as a source of independent learning because it requires the involvement of students in exploring and guiding learning. The application of probing and prompting techniques is expected to make students more interactive in learning. So that student curiosity can increase in accordance with the expected learning objectives. This research was motivated because probing and prompting techniques had never been applied at SMA Negeri 4 Padangsidimpuan. This study aims to determine whether there is an influence of the application of probing and prompting techniques on students' curiosity and learning outcomes on oxidation reduction reaction material in class X MIA SMA Negeri 4 Padangsidimpuan. The data on the curiosity test of students in the experimental class was with an average of 49.37 and in the control class was with an average of 49.17, so students' curiosity was higher in the experimental class. Then classes that used Probing and Promting techniques obtained an average learning outcome test of 36.47 to 79, so there was an increase.

Abstract

This research aims to explore educational paradigms through various ideological lenses, namely fundamentalist, modernist and liberal, in the context of finding the influence between education and the three ideologies of fundamentalist, liberalism and modernism. In achieving this goal, this research adopts a qualitative approach to understand how each ideological view contributes to the development of holistic and inclusive education. By focusing on the discourse between maintaining traditional values in education and encouraging innovation to adapt to current and future needs, this research offers a comprehensive perspective on how educational institutions can embrace these aspects to create a dynamic and relevant learning ecosystem. It is hoped that the research results will provide insight for policy makers, educational practitioners and other stakeholders in formulating educational strategies that combine harmonization between respect for cultural heritage and the application of innovative approaches that encourage students' creativity and critical skills.

Abstract

The birth of the REACT Model was initiated by CORD in the United States. This learning approach includes five learning principles which include the relationship between concepts (Relating), direct experience (Experiencing), application in real situations (Appliying), cooperation between students (Cooperating) and transfer of learning to other situations (Transferring). This learning approach makes it easier for students to understand and master redox reaction material. The aim of the research is that it is hoped that through this research, it will be possible to find out to what extent the REACT learning model contributes to improving student learning outcomes in understanding the concept of redox reactions. This study is a quantitative study. The sampling method for this study is random sampling. Collect data through learning outcomes tests. In the experimental class the average score obtained after implementing the REACT learning model was 73.33 and 60.33 in the control class and the results of the independent t test using SPSS obtained a sig value of 0.025 < 0.05 which shows that the REACT learning model can improve results.

Abstract

The integration of augmented reality (AR) technology into education has gained attention as an innovative tool to enhance students' learning experiences, particularly for abstract concepts such as chemical bonding. E-modules that incorporate AR can provide three-dimensional visualizations, making complex topics more accessible and engaging. This study aims to develop and validate practical e-modules using AR technology to enhance students' spatial intelligence while incorporating local wisdom from Padangsidimpuan. The research follows a Research and Development (R&D) approach using the Analysis, Design, Development, Implementation, and Evaluation (ADDIE) model and a pretest-posttest control group design. Data were collected from three high schools in Padangsidimpuan using simple random sampling. Instruments included validation sheets (for material, media, and language), observation, user response questionnaires, and pretest-posttest tests to assess students' spatial intelligence. The e-module achieved high validation scores: 0.9 (material), 0.8 (media), and 0.9 (language). Student response rates were 80% (feasibility), 85% (AR usage), and 83.2% (language). Teachers provided an average response score of 88.6, indicating high practicality. The spatial intelligence assessment across the three schools yielded an average score of 0.85 in the high category. The AR-based e-modules effectively improve students' spatial intelligence by visualizing abstract chemical bonding concepts in 3D. This innovation contributes to enhancing chemistry education and preserving local wisdom in Padangsidimpuan, offering a model for future educational advancements.

Abstract

kan mas (Cyprinus carpio L) merupakan salah satu jenis ikan yang menjadi kegemaran masyarakat sumatera utara khususnya Tapanuli bagian selatan, Karena selain rasanya gurih juga harganya relatif murah. Ikan mas merupakan ikan air tawar yang penyebarannya tersebar di Sumatera utara khususnya di Tapanuli Selatan. Selain langsung dimasak, olahan menggunakan ikan mas juga di awetkan dengan cara pengasapan. Namun ikan asap hasil proses pengasapan ini mudah rusak karena kadar air yang terkandung didalamnya (sekitar 60%), selain itu pengasapan terbuka yang sering digunakan masyarakat dapat menyebabkan polusi udara. Penelitian ini bertujuan untuk menghasilkan alat dengan sistem pengasapan yang dapat meningkatkan kualitas dan jumlah ikan asap. Penelitian ini menggunakan ikan mas sebagai bahan baku dan tempurung kelapa sebagai bahan bakar. Lama waktu proses pengasapan adalah 10 jam dengan variasi laju alir udara suplai yaitu 6,5 m/s, 7,5m/s, dan 8,5 m/s. Temperatur ruang oven dijaga pada suhu 80-100oC. Rata-rata penurunan dan air pada kecepatan aliran udara 6.5 m/s adalah 62,22, sedangkan rata-rata penurunan dar air pada kecepatan aliran udara 7.5 m/s adalah 58,89, rata-rata penurunan dar air pada kecepatan aliran udara 8.5 m/s adalah 45,78.
