Abstract

English extracurricular activities are one of the school's strategies to improve students' English language skills, especially at the elementary level. This study aims to determine the effect of English extracurricular activities on students' English proficiency improvement. This research employed a quantitative approach using a quasi-experimental method with a one-group pretest-posttest design. The population consisted of all students at SD Cinta Budaya Medan who participated in the English extracurricular program. A purposive sampling technique was used to select 30 active participants. Data were collected through English language proficiency tests administered before and after the extracurricular program and analyzed using the Wilcoxon Signed Rank Test. The findings show a significant improvement in students’ English skills after participating in the program. This study presents a novelty by highlighting the effectiveness of extracurricular activities as a non-formal educational intervention that positively impacts language acquisition. The implication encourages schools to maximize extracurricular programs as an integral part of the learning process outside formal instructional hours.

Abstract

Traditional file sharing systems that rely on centralized servers face various challenges. problems such as vulnerability to censorship, blocking, and server failures.This research focuses on the need for file sharing technology that is more secure, censorship-resistant, and does not rely on a single central authority. Challenge the main challenge in developing a new file sharing system is how to overcome the limitations of network scale, slow access speed, and lack of incentives for node providers. Research purposes this is to analyze the role of the InterPlanetary File System (IPFS) in building a censorship-resistant file sharing infrastructure and evaluate its benefits and constraints compared to conventional file sharing systems. Findings from the literature study show that IPFS has advantages in data decentralization, increasing information availability, and strengthening resistance to censorship. Research results also revealed that although IPFS is able to overcome many weaknesses of traditional systems, further development is still needed in terms of network efficiency and user incentives. In conclusion, IPFS has great potential to become the main foundation in a future digital ecosystem that is more open, secure, and free from third-party intervention.

Abstract

Social media has become a primary platform for Generation Z to access various types of information, including health education. This study aims to analyze the impact of health education content on social media on behavioral changes towards a healthy lifestyle among Generation Z. The research employs a quantitative approach through a survey involving 53 respondents aged 17-22 years. The findings indicate that health education content on social media effectively raises awareness of the importance of a healthy lifestyle, including balanced nutrition, sufficient physical activity, stress management, and mental health awareness. Additionally, influencers and online communities play a significant role in shaping sustainable healthy habits. However, this study also highlights the challenge of misinformation and hoaxes, which can affect understanding and decision-making regarding health. Therefore, improving media literacy is crucial for Generation Z to differentiate between credible and unreliable information. Furthermore, the involvement of healthcare professionals in producing educational content is essential to ensure accuracy. Thus, social media can be optimized as a more effective, reliable, and impactful health education platform for Generation Z.

Abstract

This study aims to produce a valid and reliable Science Process Skills (KPS) assessment instrument in learning Physics temperature and heat material. The research is a Research and Development study with the ADDIE model. The research was conducted at Dr. Wahidin Sudirohusodo Junior High School in Medan. The sample in the study came from 2 physics education lecturers and 3 physics teachers. The instruments in this study were a 15-item multiple choice KPS test sheet and a validation questionnaire. Data collection techniques in the form of tests and validation questionnaires. The KPS indicators studied were observing, formulating hypotheses, identifying variables, interpreting data, communicating, and applying concepts. Data analysis is quantitative and qualitative data analysis with the help of the SPSS version 21 application. The results validation value of 34%, language validation of 31% and validation of 35% with decent criteria, reliability of 0.862 high criteria. This finding explains that the KPS instrument is very valid and reliable to be used in learning physics temperature and heat material.

Abstract

This study examines the effect of Quibot, a chatbot-based learning medium, on students’ learning outcomes and learning motivation in mathematics learning at the junior high school level. The study was motivated by the limited integration of interactive digital media and its impact on students’ academic performance. A quantitative quasi-experimental design was employed involving 60 eighth-grade students of Yayasan Perguruan Sultan Iskandar Muda, divided into an experimental group using Quibot and a control group using conventional learning methods. Learning outcomes were measured using a validated multiple-choice mathematics achievement test, while learning motivation was assessed through a Likert-scale questionnaire. Data were analyzed using normality and homogeneity tests, followed by one-way ANOVA for learning outcomes and Welch’s t-test for learning motivation. The results showed a significant difference in learning outcomes between the two groups, F(1,58) = 4.65, p = 0.035, with a moderate effect size (η² = 0.074). However, no significant difference was found in learning motivation (p = 0.871). These findings indicate that Quibot effectively improves students’ academic achievement but does not significantly influence learning motivation within a short intervention period. This study highlights the role of chatbot-based learning media as an instrumental tool in supporting cognitive learning outcomes.

Abstract

Covid-19 which is endemic in Indonesia has damaged the entire fabric of Indonesian society, one of which is in the field of education. Education in Indonesia has not been able to be carried out normally as usual since mid-March 2020. This research aims to compare student learning outcomes before and after the Covid-19 outbreak in the Visual Communication Design (DKV) Department of SMK Negeri 10 Medan. The type of research that will be used is observational research. with a comparative or longitudinal research design. The population of this study were all students of the DKV Department at SMK Negeri 10 Medan who took Informatics subjects. This research sample was taken using a stratified random sampling method. Researchers used quantitative data analysis techniques. Data analysis shows a significant decline in student informatics learning outcomes after the COVID-19 outbreak compared to before the outbreak. The availability of devices such as computers or tablets and a stable internet connection greatly influences the effectiveness of online learning. Students who receive support and guidance from their families during online learning show better learning outcomes. Interactive teaching methods and the use of various online learning tools can improve student learning outcomes.
