Abstract

Guru Kinayan, located at the foothills of mount Sinabung in Karo regency, is characterized by several geothermal manifestations, highlighting the necessity of studying its geothermal potential. This research aims to assess the geothermal prospects of the area through 2-D electrical resistivity, geomagnetic surveys, and (XRD) methods. To acquire 2-D resistivity data, a Wenner Schlumberger array with a 5-meter electrode spacing was utilized, and the data were processed using Res2Dinv. Geomagnetic surveys were conducted using a PPM, with the results analyzed using Mag2dc and Surfer 13 to determine susceptibility results. The analysis of rock composition was performed using XRD. The 2-D resistivity results indicated resistivity values ranging from 1 to 1250 Ωm. Values between 1 and 20 Ωm indicated as alluvium, indicating a reservoir for geothermal, while resistivity values >1000 indicates as limestone, which indicated as a heat conductor. The magnetic residual map shows geomagnetic values (20 to 380 nT), suggesting a geothermal source, and the susceptibility values ranging (0.0013 x 10³ to 0.0088 x 10³) indicates the presence of igneous rocks, specifically andesite lava and pyroclastic rocks. The XRD results show arsenopirit and quartz in the geothermal area. Based on the integrated results, the study area has significant geothermal potential.

Abstract

After the covid 19 period ended, learning at Medan State University was conducted face-to-face and online, creating good learning media and design is part of the effort to achieve learning objectives effectively as mandated by the education system. This study aims to develop hybrid learning multimedia assisted by telegram, which is feasible, practical and makes students independent and influential. The research was conducted at the Physics Department of State University of Medan. The phases that will be carried out during the research are needs analysis, design of learning multimedia, development and validation of learning multimedia, implementation of multimedia to students, and internal and external evaluation. The resulting product is a learning multimedia that will be applied to partners, namely students of the Physics Department who take Modern Physics courses. This multimedia was sent to the Telegram group class of 2021 B and 2021 C students. The results of this study are: (a) the percentage of assessment scores for learning multimedia from material experts is 81% and the percentage of assessment scores from media experts is 83% (b) the percentage of student independence questionnaires is 83.8% (c) the percentage of student practicality questionnaires is 88.2% (d) N-gain for PSPF 2021-B is obtained, the result obtained is 0.23 because N-gain <0.23 in the low category and N-gain for PSPF 2021-C is obtained, the result obtained is 0.3 in the medium category.

Abstract

Science process skills are very important for students to apply scientific methods and develop knowledge in order to gain new knowledge or enrich existing knowledge. Science process skills can be facilitated through learning with a Project Based Learning (PjBL) model. This research aims to identify and analyze research trends of PjBL model to improve science process skill in science learning. This research method is descriptive and analytical. The data used in this research was obtained from documents indexed by Google Scholar from 2015-2024 using Publish or Perish and Dimension.ai. Research procedures use PRISMA guidelines. The data identified and analyzed are the type of publication, publication source, and the title of research on PjBL model to improve science process skill in science learning that is widely cited. The data analysis method uses bibliometric analysis assisted by VOS viewer software. The results of the analysis show that research trend on PjBL model to improve science process skill in science learning indexed by Google Scholar from 2015 to 2024 has experienced a fluctuating increase. However, in 2024 there will be a decline in the research trend on it. There are many documents in the form of articles, proceedings, chapters, preprints and edited books that discuss research into the PjBL model to improve science process skill in science learning. Key words that are often used in research about it are local wisdom, inquiry model, PBL, scientific attitude, etc.

Abstract

The rapid advancement of technology has significantly transformed various sectors, including education, leading to the emergence of e-learning. This approach utilizes electronic media to facilitate faster and more efficient absorption of learning materials by students. One form of e-learning is the Computer Assisted Instruction (CAI) model, which integrates information technology components such as communication tools, audio, video, and images into a cohesive multimedia platform. The implementation of CAI in e-learning enables flexible learning delivery by allowing educators to present instructional content and engage learners interactively, whether in one-on-one sessions or in small groups. This model enhances the learning experience by incorporating tutorials and multimedia presentations. Physics, as a branch of natural science, plays a critical role in shaping human reasoning and intellectual development. It investigates the fundamental elements of the universe, the forces acting upon them, and the resulting interactions, ranging from subatomic particles to cosmic phenomena. Natural Science itself is more than just the accumulation of knowledge in the form of facts or theories—it also involves systematic inquiry and discovery processes. Applying the CAI model in high school physics education, particularly in the topic of straight-motion kinematics, is expected to improve students’ comprehension and conceptual understanding. Based on evaluations from media and subject matter experts, as well as product testing, the instructional media developed has been rated highly feasible, receiving an 86% approval score from users.
