Abstract

This study aims to explore students' perceptions of the use of animated video media in the learning process at SMAN 18 Medan. Animation-based instructional media are believed to enhance students' interest, understanding, and motivation, particularly when dealing with abstract material. This research employs a descriptive qualitative method by distributing questionnaires to students who have participated in learning sessions utilizing animated videos. The data were analyzed thematically. The findings indicate that students have a positive perception of the use of animated videos, as they help facilitate easier comprehension of the material, increase concentration, and make the learning process more engaging. However, some students still prefer direct instruction from the teacher. Therefore, it is recommended to combine animated video media with traditional teaching methods to create a more effective learning process that accommodates diverse student learning styles.

Abstract

Bad odor and bacterial growth in shoes are common issues experienced by many users, primarily due to the damp conditions after use. Widely available synthetic chemical-based shoe deodorants often raise health concerns and have a negative impact on the environment. Furthermore, corncobs, an abundant agricultural waste product, are underutilized, despite their carbon content and porous structure that have the potential to absorb odors and inhibit bacterial growth. This study aims to test the effectiveness of processed corncobs as a natural deodorant in reducing odor and bacteria in shoes. The research method used a qualitative approach through literature review and interviews with several informants to obtain data on community needs and the potential use of corncobs. The results indicate that corncobs have significant ability to absorb odors and reduce moisture, thereby suppressing the growth of odor-causing bacteria in shoes. Furthermore, the use of corncobs as a natural deodorant is considered safer, environmentally friendly, and has economic prospects due to its readily available and low-cost raw materials.
