Abstract

Kegiatan demonstrasi edutaiment kimia merupakan salah satu pendekatan pembelajaran yang menarik untuk meningkatkan pemahaman siswa terhadap konsep kimia melalui kegiatan eksperimen yang menyenangkan. Penelitian ini bertujuan untuk menjelaskan sifat-sifat nitrogen cair dan pengaruhnya terhadap bahan biologis seperti telur ayam melalui eksperimen “Telur Mata Sapi Menggunakan Nitrogen Cair”. Metode yang digunakan berupa demonstrasi praktikum dengan pendekatan observasional deskriptif. Hasil pengamatan menunjukkan bahwa nitrogen cair bersuhu sangat rendah (–196°C) dapat membekukan telur secara instan tanpa menyebabkan reaksi kimia, melainkan hanya perubahan fisika yang reversibel. Kegiatan ini membantu siswa memahami konsep suhu, kalor, dan perubahan wujud zat melalui pengamatan langsung terhadap fenomena pendinginan ekstrem. Dengan demikian, penggunaan nitrogen cair dalam demonstrasi edutaiment kimia efektif meningkatkan ketertarikan serta pemahaman siswa terhadap konsep-konsep dasar kimia.

Abstract

This study aims to examine the impact of TikTok scrolling activity on the reward system of elementary school children's brains, focusing on fifth-grade students at SDN 2 Berangah. Repetitive scrolling behavior on the TikTok platform is suspected to trigger excessive dopamine release, potentially affecting children's concentration, learning motivation, and impulsive behavior. The research method used is descriptive qualitative, involving classroom observation, teacher interviews, and student questionnaires. The findings indicate that intensive TikTok usage leads to decreased learning focus and increased tendencies to seek instant stimulation. These results highlight the need for adaptive educational strategies in response to digital technology developments in elementary school environments.

Abstract

Chemical edutainment demonstrations represent an engaging instructional approach to enhance students’ understanding of chemical concepts through enjoyable experimental activities. This study aims to explain the properties of liquid nitrogen and its effects on biological materials such as chicken eggs through the experiment “Sunny-Side-Up Egg Using Liquid Nitrogen.” The method employed was a practical demonstration with a descriptive observational approach. The observations revealed that liquid nitrogen, with its extremely low temperature (–196°C), can instantly freeze eggs without inducing chemical reactions, but rather through reversible physical changes. This activity enables students to comprehend the concepts of temperature, heat, and phase transitions by directly observing extreme cooling phenomena. Therefore, the use of liquid nitrogen in chemical edutainment demonstrations proves effective in increasing students’ interest and understanding of fundamental chemical concepts.

Abstract

Social media represents a form of technological advancement that is unavoidable among students. There are various types of social media platforms that are currently popular, including Facebook, Instagram, WhatsApp, TikTok, YouTube, Twitter, and Blogger. Each platform has specific advantages that attract its users, making them spend extended periods navigating the digital world. The use of social media depends on individual behavior as well as environmental influences. This study aims to determine the effect of social media usage on students’ GPA. The research employs a quantitative descriptive and inferential approach, with data analyzed using one-way ANOVA, normality testing, and homogeneity testing. The sample consisted of 31 fourth-semester students from the Chemistry Education study program. The findings indicate that students most commonly use WhatsApp (24%) and Instagram (28%), followed by YouTube (9%), Facebook (10%), TikTok (16%), Line (4%), Snapchat (4%), and X (4%). The survey also revealed a striking result regarding the intensity of social media use: 74% of students reported using social media for more than 4 hours per day, while 26% used it for less than 4 hours. Students who used social media for less than 4 hours had an average GPA of 3.23, whereas those who used it for 4 or more hours had an average GPA of 3.21. The one-way ANOVA analysis resulted in a significance value of 0.908 > 0.05, indicating that H₀ is accepted, meaning there is no significant effect of social media usage duration on students’ GPA. The normality test yielded a significance value of 0.200 > 0.05, indicating that the data are normally distributed. Meanwhile, the homogeneity test produced a significance value of 0.770 > 0.05, showing that the data are homogeneous.
