Abstract

The development of coding and artificial intelligence (AI) learning in Indonesia faces the challenge of digital infrastructure inequality, especially in 3T (underdeveloped, frontier, outermost) areas. This study aims to design and test the Box Ocean Ecosystem Sorting Media (BOESM) learning media, an unplugged media that teaches programming logic and AI concepts through marine ecosystem concept classification activities. The study employs a 4D development model (Define, Design, Develop, Disseminate) involving elementary school teachers and students who lack adequate access to digital devices. Data collection techniques include field observation, interviews, questionnaires, expert validation, and analysis of pretests and posttests. BOESM utilizes concrete objects to simulate algorithmic thinking patterns (IF-THEN logic) by grouping marine components, including fish, sand, and plastic waste. The results of expert validation showed that the media was very feasible, and the field trial produced a moderate gain score (0.52), indicating an increase in students' understanding of computational thinking. As many as 92% of students reported enjoying learning without the use of digital devices. The study concluded that BOESM is effective in fostering algorithmic thinking and early AI literacy in technologically constrained environments and is an inclusive and cost-effective learning alternative.

Abstract

Social media has become an important part that cannot be separated from the education system, not only in Indonesia but throughout the world. This is a change in mindset in learning and sharing knowledge, including Biology. Biology requires students to be able to think at a high level, understand all concepts, and must be able to relate them to natural events or happenings or to other biological concepts. Learning media that can utilize social media is one of the supports for an optimal learning process. Using Canva-based Instagram Feed learning media will make it easier for students to understand and make decisions. This research aims to develop Instagram Feed media via Canva on valid Biology material. The method used in this research is Research and Development (RD) with the ADDIE model. Stages include Analysis, Design, Development, Implementation, and Evaluation. However, this research only reached the development stage. The products that have been developed are then validated by media experts and material experts. The results show that the learning media developed has an average of 87.00, which means that the Canva-based Instagram Feed media developed is feasible or suitable for use in the learning process.

Abstract

The diversity of ferns is very high, especially in Indonesia. Ferns (Pteridophyta) are a division of the kingdom Plantae whose members have true roots, stems and leaves, as well as carrying vessels. Ferns (Pteridophyta) live in moist areas (hygrophytes) both epiphytes (attached to trees, wood, rocks) and terrestrial (soil). The diversity of ferns is related to altitude and other abiotic factors such as temperature, pH, humidity and light intensity. This research used qualitative methods through fern exploration activities in the Batang Gadis National Park, specifically at Sopo Tinjak Resort 6. The research results obtained 8 types of ferns in Resort 6 of the Batang Gadis Mandailing Natal National Park Area, North Sumatera, Indonesia.

Abstract

Gel electrophoresis is a fundamental technique in molecular biology used to separate DNA fragments by size. However, limitations in laboratory facilities often hinder its implementation. This study aims to analyze students’ understanding of the operating principles of gel electrophoresis, the functions of its main components, and their ability to interpret DNA separation results through a virtual practicum on the LabXchange platform. The study employed a descriptive qualitative approach with 63 fifth-semester students from the Biology Education Program. Data were collected through observations during the simulation, analysis of DNA band patterns generated by the virtual experiment, and students’ responses in the worksheet. The findings indicate that the virtual simulation effectively visualizes the DNA migration process, enabling students to understand the roles of agarose gel, buffer, and electrical current in fragment separation. Students identified the relationship between fragment size and migration distance and evaluated the expected results based on electrophoresis theory. Thus, the virtual laboratory practicum proved to be an effective alternative learning method for enhancing conceptual understanding and analytical skills in gel electrophoresis.

Abstract

Science students play a vital role in the advancement of information and technology; therefore, environmental awareness is a crucial component of sustainable behavior. This study aims to examine the level of environmental awareness among science students and the factors influencing it. A descriptive qualitative approach was employed, with data collected through observations, interviews, and literature reviews. The research respondents consisted of science students from the biology, chemistry, and physics study programs. The findings indicate that science students generally demonstrate a moderate level of environmental awareness, particularly in terms of knowledge. However, this awareness is not yet fully reflected in strong attitudes and consistent pro-environmental behaviors in daily life. Therefore, sustained efforts by educational institutions are necessary to enhance students’ environmental understanding and active participation in environmental protection.
