Abstract

Coffee is one of the most widely consumed beverages worldwide and contains various bioactive compounds, such as caffeine, chlorogenic acid, and polyphenols, which have the potential to affect the human digestive system. The increasing pattern of coffee consumption, especially in modern society, raises questions about its impact on digestive system performance. This article aims to analyze the effect of coffee consumption on human digestive system performance based on a review of various relevant scientific findings. This study uses a qualitative approach with a literature review method to examine the relationship between coffee consumption levels and human digestive system performance. The discussion focuses on the effects of coffee on gastric acid secretion, gastrointestinal motility, digestive enzyme activity, and physiological responses of the gastrointestinal tract. The results of the study indicate that coffee consumption in certain amounts can have a stimulating effect on the digestive system, such as increased intestinal motility and gastric secretion. However, excessive coffee consumption has the potential to cause digestive disorders, including gastric irritation and gastrointestinal discomfort. Therefore, the level of coffee consumption is an important factor in determining its effects on digestive system performance. The conclusion of this article emphasizes that coffee consumption should be done moderately to obtain its physiological benefits without causing negative impacts on the human digestive system.

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

The research-based enrichment module is a teaching material designed from recent studies and aligned with relevant learning content. This module aims to enrich students’ knowledge, improve their critical thinking skills, and enhance their understanding of current scientific concepts. This study investigated the effectiveness of a research-based enrichment module on karamunting plant identification in improving students’ learning outcomes. An experimental design with a pretest-posttest control group was applied. The population included 157 Grade X students at SMK Pertanian Pembangunan Negeri Sembawa. Using cluster sampling, 30 students from Grade X ATP 1 (control) and 30 from Grade X ATP 2 (experimental) were selected. The experimental group used the enrichment module, while the control group did not use any additional learning materials. Data were collected through cognitive learning outcome tests and analysed using descriptive statistics and a paired sample t-test. Results showed the experimental group achieved a mean post-test score of 81.67, compared to 70.50 in the control group. The paired sample t-test indicated a significant effect (p = 0.000, p 0.05). Thus, the enrichment module on karamunting identification significantly improved students’ cognitive learning outcomes.

Abstract

The research is motivated by the suboptimal use of video learning media, which does not meet the need for engaging, easily understandable, and relevant learning media that align with the current visual and digital learning habits of students. The learning media used are still not optimal, resulting in low student learning outcomes. This research was conducted with the aim of developing valid, practical, and effective learning video media using the CapCut application on the topic of the human circulatory system for 11th-grade students. The method used in this research is development research (RD) with the ADDIE model, which includes five stages: analysis, design, development, implementation, and evaluation. The subjects in this study were 30 students from class XI-7 for the 2024/2025 academic year. The data collection instrument was in the form of validation questionnaires from media, material, and language experts. The questionnaire measuring practicality was distributed to biology teachers and students, while the effectiveness was measured using a pretest-posttest. Data were analyzed descriptively using both quantitative and qualitative methods. The research results show that the developed video media has a validity level from media experts of 98.08% (very valid category), material experts of 92.5% (very valid category), and language experts of 100% (very valid category). Additionally, the response from teachers was 89.58% and the response from students was 93.5% (very practical category). The results of the effectiveness test using student test scores showed a pretest percentage of 67.26% and a posttest percentage of 84.6%. To see theimprovement in student learning outcomes, the N-Gain was calculated with a percentage of 50.99%, categorized as quite effective. Therefore, this CapCut-based learning video media can be used as an effective alternative media in the Biology learning process, especially on the topic of the human circulatory system.

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.
